Teaching
I take great personal satisfaction from my work as an educator at the University of Missouri-Columbia. Individuals involved in education (both professors and students) have an obligation to respect the process of education and promote excellence at all levels. My responsibility as an educator is to perform at a high level both inside (formal lecture setting) and outside (one-on-one time with students) the classroom. I expect my students to perform at a high level as well. Rigorous academic training is no longer optional. It is a necessity for students that want to tackle the intellectual challenges of the 21st century. The animal science profession (including agribusiness people, researchers, and educators) needs motivated and knowledgeable people. My job is to motivate and train those people.
I am primarily involved in graduate education. Most of my students become involved in science or education. For graduate students, I believe that their educational experience must include research (scholarship) as well as formal coursework in a classroom setting. Formal coursework is important because it is the last opportunity for graduate students to learn new information in a structured environment. Once students begin their professional careers, there is little time to go back and learn the basics. Graduate students should not waste their last opportunity for formal training by taking the minimum number of classes or neglecting the classes that they take.
As educators, we have an obligation to present the most up-to-date information and present it in a format that is stimulating to our students. I give traditional lectures in Animal Science (AS) 8420 (Endocrinology). I find that this format is the fastest way to convey the tremendous amount of new information in endocrinology. I also think that students like lectures as long as they are stimulating and interesting. I keep things interesting by interjecting new discoveries reported in Science magazine as well as the popular press. Students pick-up on this and bring in articles that they find interesting. When a student brings in an article, I photocopy it and present it to the class. The emphasis on current literature helps students feel that they are learning up-to-date and relevant information.
I give challenging exams in Endocrinology because I believe that the best courses are those that demand excellence from students. Not unexpectedly, I find that students are eager to rise to the challenge of a difficult exam. I praise the class when they do well and I chastise the class when they do poorly. It is all part of the process of showing them that I care about them, I am committed to the subject, and I want them to learn the material.
One innovative way that I involve students in AS 8420 is through “minipapers.” Minipapers are one-page summaries of research papers. Four times during the semester, I select a topic and ask students to find a recent research article. Students are encouraged to find “interesting” papers (something a little different or unusual usually gets the best grade). I grade the papers and then we devote one day for informal presentations of selected papers. It is a lot of fun because students get a chance to informally talk about endocrinology. One topic that I really like is “endocrine changes in our daily lives.” I ask the students to find a paper on hormones whose concentrations change when we do things. The most interesting papers with the most interesting activities get the highest grades. We’ve discussed hormonal changes during marathon running, mountain climbing, sky diving, sleeping, movie watching (horror, erotic, action), eating, etc. (you name it, we’ve talked about it!). We have a lot of laughs about how our endocrine systems respond to lots of different things. The focus is on having fun and reinforcing the idea that what we are learning is relevant to our everyday lives.
I cannot understate the importance of enthusiasm when teaching. This is an aspect of my personality that students consistently comment upon. I try to convey excitement and amazement for the material that I present. Students pick up on my actions and are motivated to truly listen to my words. My greatest satisfaction comes when a student stops by after class and asks for more information. That tells me that I have sparked a desire to learn outside of the classroom.
You may notice some references to football in the comments below. Why do I talk about football in endocrinology? First, it humanizes me as a lecturer. I relate to the students on a neutral subject about which they probably know as much as I do. It also helps the class to get to know each other. Most graduate students did their undergraduate work away from MU. I keep track of the football scores from their respective undergraduate institutions. On Monday morning, I compliment the winners and also tease the losers, especially when they played MU. We also have two informal contests every year. The first contest is to predict the score of the MU-Nebraska football game. This started out as a joke (mid 90’s) but has become a greater challenge lately because the MU teams are better. The winner gets an MU t-shirt (I won this past year, a first!). The contest relates back to the idea of getting to know each other and having some fun. I also award a frozen turkey to the best minipaper of the year. It has become quite a contest with students vying to find the most interesting paper.
This past year I incorporated some long-overdue technology into my endocrinology lectures. Chalk and blackboards always frustrated me because you erase (and essentially lose) everything you write down. I am also allergic to chalk dust (something I inherited from my dad). Pre-made PowerPoint presentations are too structured for the interactive environment that we have in class. The Animal Science Department recently outfitted several lecture rooms with computers, write-on computer screens, and computer projectors. I use the write-on computer screen and projector instead of a blackboard (Smart Notebook software). The Smart Notebook is great because a series of individual “blackboards” are created. I can go back and forth between boards during lecture. At the end of lecture I save all of the blackboards as a single PDF file. I print out the PDF (a record of the lecture) and post the PDF on MU libraries ERES (electronic reserve). Students who missed class or missed a point made in class can access the notes in ERES. Several students commented on how much they liked this new technology. I liked it as well because it was simple, easy to use, and fit into my existing lecture format. The computer projector also allows me to use the National Center for Biotechnology Information (NCBI) structure data base to show three dimensional models of hormones and their receptors. The use of the web in class exposes students to scientific resources and demonstrates the power of the web as a teaching, research and discovery tool.
I’ve commented on classroom teaching but I have not touched upon graduate training (M.S. and Ph.D. students working in my laboratory). Some might argue that graduate training and classroom teaching are two different things but I apply the same elements to both forms of teaching. The mentor of a graduate student must demand excellence and challenge the student, care about the student as a person, instill enthusiasm and love for science, and have fun in the process. I think that I create these things for the graduate students in my laboratory.
I teach Endocrinology in the fall and Reproductive Biology Seminar (AS 8413) in the winter. Animal Science 8413 is a seminar course that students in reproductive biology can take to fulfill a seminar requirement. Students practice public speaking by presenting a seminar based on a recent scientific paper. I work with students by listening and critiquing their seminar before it is given to the rest of the students and faculty. After the formal seminar is presented, I prepare a memo that includes an evaluation of the presentation.
One goal for my teaching was to use the internet to improve my classes. Therefore, I attended the ET@MO Faculty Institute in January 2002. Using what I learned, I introduced a new “online” (WebCT) version of AS 8413 in winter 2002. The WebCT site for the course has the syllabus, general information for students, an online discussion, seminar calendar, class email, study questions, and a link to ERES. Students post their PowerPoint presentations and their papers (PDF files) on ERES. Students taking the class are asked to look at the PowerPoint presentations and comment on them in the online discussion. They also must read the paper and answer an online study question. Grading and feedback are all done online.
The WebCT course actually creates some additional work for me, but I use the online format anyway. Many of the students will go on to pursue teaching careers. I want to expose them to the online technology that is available for teaching. I also want to show them that as a teacher you can adapt and evolve with new technology. I will not use WebCT in 2005 because I have temporarily moved away from an emphasis on the current literature. The 2005 topic is “100 years of Reproductive Biology at MU.” Students have been assigned one of eight famous reproductive biologists who were either MU faculty or trained at MU. The list of faculty begins with Frederick Mumford; the first dean of the College of Agriculture. Students will study the life of each person and present a biography at our regular weekly seminar.
I’ve tried to convey my teaching philosophy. It boils down to a commitment to excellence, a sincere belief in higher education, a love for students and learning, a little bit of enthusiasm and a dose of fun. I think that these principles go a long way toward a meaningful college education.

Extension
Summary of Activities
There is no extension appointment associated with my position. Nevertheless, the applied aspects of my laboratory’s work are of interest to farmers and veterinarians. Members of my laboratory and myself are experts in the field of ovarian and uterine (pregnancy diagnosis) ultrasonography in cattle and swine. A second important area of applied research is our work with the controlled internal drug releasing (CIDR) device for estrous synchronization in cattle. I offer expert advice on the CIDR to farmers, veterinarians, and extension agents. My laboratory also presents general information on livestock reproduction to a wide range of audiences.

Research
Statement of the Problem
I study the reproductive biology of farm animals. Reproduction is important to farmers because the rate at which a farmer can produce youngstock (calves, piglets, lambs, etc.) determines the overall profitability of a farm. Pregnant animals, therefore, are very valuable whereas infertile animals have very little value. In dairy cattle, the value is not in the calf but in the milk that the mother produces after she has a calf. To make milk, however, the dairy cow must give birth to a calf. The value of pregnancy can be illustrated by comparing the value of a pregnant animal with that of a nonpregnant animal. A pregnant dairy cow is worth approximately $1400 because she will eventually calve and produce milk. A nonpregnant, infertile dairy cow is worth about $300 and can only be sold for meat. Therefore, $1100 is lost because the cow is not pregnant. As illustrated by the preceding example, a pregnancy is very valuable to a farmer. Therefore, my research focuses on how to maximize the number of pregnant animals in a herd.
There are several physiological constraints to the establishment of pregnancy. First, the female may not have regular reproductive cycles. This type of failure is called anestrus and is common among farm animals during the postpartum period. Essentially, the reproductive system is not functioning.
A second, perhaps more frustrating type of reproductive failure occurs after the female has successfully mated. The oocyte (female gamete) may be released but may not be fertilized. If the oocyte is fertilized then the embryo may die prematurely inside the uterus. This phenomenon is known as “early embryonic death.” Early embryonic death is a major cause of pregnancy loss in farm animals. The underlying mechanisms for this loss are poorly understood. A combination of genetic and environmental factors may be involved.
A single scientist cannot study all aspects of reproduction in farm animals. I study follicular development; the process by which the follicle grows prior to ovulation. Follicular development is one component of anestrus because follicles fail to grow normally and ovulate in anestrus animals. Follicular development is also one component of early embryonic death. Although the follicle may appear normal, it can release an oocyte that is incapable of fertilization or incapable of normal development after fertilization.
Causes of Anestrus and Infertility
The primary cause of anestrus in postpartum farm animals is inadequate nutrition. In beef cattle, inadequate nutrition occurs during the winter when pasture conditions are very poor and animals cannot forage for adequate food. Farmers can supplement the diet of a wintering cow but their efforts often fall short of the nutrient requirements. In springtime, the cow calves but she may be too thin because of weight loss during the winter. Pastures improve in the springtime but the additional energy demands of lactation may prevent the cow from gaining weight while consuming the springtime grasses. The end result is a nutritionally anestrus cow that cannot become pregnant during the springtime breeding season (about 60 to 90 days after calving). If she fails to become pregnant, she must be sold as a cull cow after her calf is weaned.
Postpartum dairy cows and pigs are fed ad libitum amounts of high-energy diets during lactation. Nevertheless they also suffer from anestrus. The reason is that the amount of energy that the animal can partition to milk exceeds the amount of energy that she can consume. When faced with the energy deficit, the postpartum dairy cow and pig use body fat to support the lactation. Like the postpartum beef cow, the weight loss caused by fat mobilization in dairy cattle and pigs leads to anestrus and infertility. The cost of any delay in pregnancy can be very high ($2 to 4 in lost income per day). Pigs must be in estrus within seven to ten days after their young are weaned. Otherwise the postpartum pig will become asynchronous with her farrowing group and may be culled for reproductive failure.
Mechanisms Linking Nutrition to Reproduction
How does undernutrition affect reproduction in farm animals? Anestrus occurs when the follicle fails to ovulate. To ovulate, follicles depend on hormones and growth factors that are produced locally (i.e., within the follicles) as well as externally (i.e., outside the follicle from other tissues). One class of hormones [the gonadotropins: luteinizing hormone (LH) and follicle stimulating hormone (FSH)] arises from the pituitary and stimulates follicular growth. Of the two gonadotropins, LH is the most notably affected by nutrition. In normal animals, LH is secreted in pulses that hormonally stimulate follicular growth. Undernutrition blocks LH pulses and therefore blocks follicular growth. The mechanism through which undernutrition blocks LH pulses is complex and poorly understood because LH is ultimately under the control of higher brain centers that are difficult to explore scientifically.
In addition to LH, the ovary also depends on the hormonal actions of several growth factors. These growth factors include growth hormone (GH) and insulin-like growth factors (IGF-I and IGF-II). Insulin-like growth factors-I and –II are related hormones but IGF-I has greater potency and may be more important than IGF-II for a variety of functions in adult animals. Insulin-like growth factor-II, however, is an important fetal hormone. The IGFs induce the expression of receptors for LH and FSH. Therefore, without a minimum level of IGF, the ovarian cells cannot respond properly to LH or FSH because they fail to express gonadotropin receptors. The IGFs that act on the ovary come from two sources. There is local production of IGFs by ovarian cells (autocrine/paracrine IGF) as well as external production of IGF by the liver.
Areas of Research
We study both GH and IGF-I. Growth hormone is a pituitary hormone that promotes growth. Receptors for growth hormone are located throughout the body. The largest concentration of GH receptors, however, is found within the liver. Growth hormone acts on the liver and causes the synthesis and secretion of IGF-I. The IGF-I secreted from the liver acts as an endocrine hormone by stimulating a variety of cells throughout the body (including ovarian cells). One of the endocrine consequences of inadequate nutrition is a decrease in blood concentrations of IGF-I. The decrease in blood IGF-I is caused by a decrease in liver IGF-I synthesis and secretion. Liver IGF-I synthesis is decreased because the liver does not respond to GH in animals that are undernourished. Our hypothesis is that the decrease in blood IGF-I in undernourished animals causes a reduction in gonadotropin signaling within the ovary. The loss of gonadotropin signaling drives the animal into anestrus.
Growth hormone, IGF-I, and ovarian function. We examine aspects of this hypothesis in molecular (basic) as well as whole animal (applied) studies. The work on GH began during my Ph.D. when we demonstrated that dairy cows injected with exogenous GH have an increased amount of follicular growth on the ovary [17, 18 (the numbers correspond to journal articles listed in this dossier)]. Our early work showing greater follicular growth in GH-treated cows was also confirmed in later studies in my laboratory at the University of Missouri (37, 38). Exogenous GH increases blood concentrations of GH and IGF-I. The fact that cows treated with exogenous GH had greater follicular growth suggested that the ovarian follicles respond positively to increased concentrations of GH and (or) IGF-I. A critical question that needed to be addressed, however, was whether or not GH could act on the ovary directly. The alternative possibility was that the actions of GH were solely mediated by an increase in liver IGF-I secretion that was caused by the exogenous GH (i.e., an endocrine mechanism for GH action). I examined this possibility during my postdoctoral work at Monsanto. Bovine ovaries were tested for GH receptor expression (19). We found that the corpus luteum (CL; structure that forms after ovulation of the follicle) was a rich source of GH receptor mRNA and protein. Follicles, however, had very little GH receptor. From this work, we hypothesized that the CL may respond to GH (because CL contains the GH receptor) but follicles were probably responding to the increase in blood IGF-I that occurred during GH treatment. We later found that exogenous GH (22) and placental lactogen (23; placental lactogen is GH-like molecule produced by the placenta) could affect the growth of the CL. These early studies formed the basis for my first USDA grant entitled “Effects of growth hormone on functions of the corpus luteum in cattle.” Several publications arose from this grant including one that showed greater progesterone synthesis in luteal cells treated with GH (28).
Ovarian gene expression for GH and IGF genes. When we began our work, little was known about the local architecture of GH receptor, IGF-I or IGF-II gene expression within the bovine or porcine ovary. We addressed this question in a series of studies that employed in situ hybridization. In situ hybridization is a powerful technique because it allows you to examine mRNA expression within histological sections. We did studies in both cattle and pigs to determine where the GH receptor and IGF genes were expressed (32, 33, 40, 57). Our sow work was funded by a USDA grant entitled “Follicular growth in sows.” We confirmed that there is very little GH receptor within the follicle but abundant GH receptor within the CL. The research also showed that IGF-I mRNA was located within the granulosa cells of the follicle whereas IGF-II mRNA was located in the theca cells (cell layer immediately outside the granulosa cell layer). Our data on IGF-I gene expression were unique because other groups failed to detect IGF-I in ovarian granulosa cells. We also examined IGF binding proteins and showed that growing follicles made less IGF binding protein than non-growing follicles (40, 57). Binding proteins block the actions of IGF-I. The data suggested, therefore, that low IGF binding protein may be one mechanism to increase IGF action within the growing follicle. We are expanding our search for genes involved in follicular growth by sequencing EST from porcine ovary (Monsanto Pig Genome Project). We have created cDNA libraries from fetal ovary, neonatal ovary, prepubertal ovary, and follicle (2 mm to 8 mm) and sequenced approximately 12,000 cDNA (67; see also abstract no. 91). The cDNA are organized into a database and are being used to create porcine ovary microarrays. These arrays will be a unique resource available to investigators inside and outside the University of Missouri.
Nutritional regulation of reproduction in sows. In addition to our work on gene expression in pig ovary, we also perform whole animal research in sow reproduction. Our whole animal research is funded by our current USDA grant entitled “Interval to ovulation in weaned sows.” We discovered that ovarian follicular development before weaning is heterogeneous and that multiple patterns of development are seen when individual sows are compared. Based on our most recent data, we have developed a conceptual model for follicular growth and estrus in weaned sows. The model includes endocrine mechanisms (i.e., individual differences in insulin, IGF-I, LH, and FSH), behavior mechanisms (relationship between follicular growth and the initiation of estrus) and morphological mechanisms (i.e., timing of weaning relative to ovarian follicular development). We summarized the model in a presentation to the Sixth International Symposium on Pig Reproduction in Columbia, Missouri (see Book Chapter no. 8).
Molecular biology of the GH receptor. When we first discovered GH receptor in the ovary, we wanted to know whether or not the receptor was different from the traditional form of the GH receptor found in the liver. We isolated cDNA clones for GH receptor and found that the GH receptor in ovary was different from that found in the liver (31). The difference, however, was not within the portion of the cDNA that encoded protein. Instead, the difference in the cDNA was within exon 1 (the region associated with GH receptor promoter). These data led us to the conclusion that the GH receptor gene is under the control of several gene promoters. The transcript that we discovered in the bovine ovary (GH receptor 1B) arose from the second of three GH receptor promoters (P2; 31). We later showed that P2 was active in most bovine tissues (41). The liver expresses both the P1 and P2 promoters (41). Our work in the bovine agrees with work in other species showing at least two GH receptor promoters. We also showed that a third promoter (P3) is active in the bovine (47). The P3 promoter is similar to P2 in tissue distribution and activity. Our publication on P3 was the first report in any species showing a third GH receptor promoter.
We knew that the liver could respond to GH by increasing IGF-I synthesis and secretion. We also knew that the reproductive tract could produce IGF-I (i.e., local IGF-I synthesis). Thus, we wondered whether or not the IGF-I within the reproductive tract was under GH control. To address this question, we treated cows and pigs with GH and examined the expression of IGF-I within the reproductive tract (25, 34, 45). Surprisingly we found that IGF-I mRNA expression within the ovary and uterus was independent of GH. In other words, unlike the liver, where GH can control IGF-I synthesis, the IGF-I in reproductive tissues was expressed constitutively. We examined the question in another way by testing ovarian IGF-I gene expression in heifers that were deficient in GH (30). The GH deficiency was induced by immunization against GH releasing factor and causes low blood IGF-I concentrations. We found that ovarian IGF-I gene expression was unaffected by the GH deficiency. Therefore, GH was not controlling ovarian IGF-I. Growth hormone deficient heifers (with low blood IGF-I), however, had less follicular growth. Thus, normal blood IGF-I concentrations were necessary for normal follicular growth. We made similar findings when we examined follicular growth in a line of cattle with a GH receptor deficiency that led to high blood GH but low blood IGF-I concentrations (39, 52).
The liver produces about 80% of the IGF-I circulating in blood. The synthesis and secretion of liver IGF-I depends on the amount and activity of the GH receptor in the liver. Furthermore, the GH receptor in liver is under nutritional control. It was important, therefore, to explore the molecular control of the GH receptor gene. Much of this work from our laboratory was funded through our third USDA grant “Structure and function of the growth hormone receptor gene in cattle.” As mentioned above, the GH receptor is under the control of at least three promoters (P1, P2, and P3). We were the first laboratory to clone P1 from cattle (26) and show that a genetic polymorphism was present within P1 (44). The polymorphism that we discovered can be used to predict animal growth (58). We have also completed an initial characterization of P1 and P2 in the pig (53). In cattle, the P2 and P3 are similar because both are constitutive promoters that are active in a wide variety of cell types. Within the genome, P2 and P3 are within 800 bp of each other and share a common enhancer element containing a GC and CAAT box (47, 54). We characterized the enhancer by DNAse footprinting, gel shift, and cell transfection analyses. The enhancer is required for normal promoter activity because promoter activity is lost when the enhancer is mutated or deleted. Transcription factors that bind the enhancer have a ubiquitous expression pattern and this explains why we detect P2 and P3 transcripts within almost every bovine tissue (41, 47). In vitro analyses of P1 demonstrated that hepatocyte nuclear factor-4 (HNF-4) is one of the transcription factors controlling P1 activity (65). Hepatocyte nuclear factor-4 is highly enriched in liver and is a logical candidate for a transcription factor controlling liver-specific expression of P1. Our lab was the first to demonstrate the importance of HNF-4 in liver-specific GH receptor expression.
Perhaps the most important GH receptor promoter is P1. The P1 is the liver-specific promoter for GH receptor. The P1 is important because it contributes to the total amount of GH receptor in liver. Furthermore, the efficiency of translation for P1 mRNA may be greater than the efficiency of translation for P2 mRNA (59). P1 is not a constitutive promoter like P2 and P3. Therefore, the activity of P1 changes with the physiology of the animal. For example, P1 activity increases after birth (70), increases in response to GH (51) and insulin (78) and increases in late-pregnant cows (51). We recently discovered that P1 activity is specifically down regulated in periparturient cows that have low blood IGF-I concentrations (50). The next step in our investigations is to specifically demonstrate that P1 activity controls the amount of GH receptor protein and GH receptor second messenger activity in liver. We also want to determine the physiological mechanisms that lead to the rapid decrease in P1 activity in periparturient cattle (50). These most recent studies are funded by our current USDA grant entitled “Growth hormone receptor 1A in periparturient dairy cattle.”
Conclusions
In the preceding paragraphs, I have attempted to present the current status of my research program and place it into the context of animal agriculture. Our studies focus on GH and IGF-I. Changes in blood IGF-I affect the ovary because IGF-I syngerizes with gonadotropins to stimulate ovarian function. Ovarian IGF-I is a summation of local (paracrine/autocrine) and liver (endocrine) components. Therefore, developmental and nutritional changes in liver GH receptor and IGF-I affect ovarian function through changes in the blood concentrations of IGF-I. We want to understand GH receptor and IGF-I gene expression. If both genes can be understood, and ultimately controlled, we may be able to increase the number of pregnant animals in a herd by managing GH receptor and IGF-I gene expression.

SERVICE
Description of Service Assignment
I serve in a variety of capacities at the local and national level. Much of my present service time is spent reviewing manuscripts for journals and reviewing grants for granting agencies. I am a proponent of the peer review process and believe that faculty must devote some of their time for this work. In past years, I served as a member and chairman of the National as well as Midwestern ASAS/ADSA Physiology committees. At the campus level, I serve as Leader of the F21C Animal Reproductive Biology Cluster (appointed October 2004) and organize the F21C Animal Reproductive Biology Seminar series. I am appointed to several departmental committees.

F21C Reproductive Biology Fall Seminar Series
One of my informal assignments is to organize the fall semester F21C Reproductive Biology Faculty Seminar series (Wednesdays at 4 pm; 1996 to present). This work involves filling the seminar calendar (approximately 15 dates), sending out fliers, setting up the room before seminar, and introducing the speakers. Approximately 30 people attend the seminar weekly.
