Ahmed Balboula, PhD

Assistant Professor, Division of Animal Sciences

Microtubules, Centrosome, Meiosis, Oocyte, Fertility

Ahmed Balboula, assistant professor in animal sciences, is working to understand how chromosome segregation is regulated in female gametes (oocytes). During the early stages of pregnancy, chromosome mis-segregation can result in aneuploidy (abnormal number of chromosomes in a cell), the leading genetic cause of miscarriages and congenital abnormalities. His work has implications for both animal and human health. Balboula recently received R35 grant (Outstanding Investigator Award) through the National Institute of General Medicine (NIGMS, NIH) totaling $1.9 million for a five-year period. Funding is for a project titled Mechanisms Underpinning Meiotic Spindle Formation and Behavior. Balboula is a reproductive biologist, interested in cell biology and genetics. He is aiming to understand molecular mechanisms that regulate oocyte meiosis and preimplantation embryo development.

Susanta Behura, PhD

Assistant Professor, Division of Animal Sciences

Fetal brain development, Developmental Origin of Health & Diseases (DOHaD)

Behura performs interdisciplinary research in the areas of reproductive biology. He applies informatics and data science tools in diverse research projects relating to reproduction and development, functional genomics, bioinformatics and computation biology. His lab investigates molecular and cellular regulation of fetal brain development, primarily in mice and pigs. His lab uses multiomics data from transcriptomics, epigenetics, metabolomics, proteomics, and single-cell genomics assays to address questions relating to the regulation of brain-placental axis, effects of sex on brain development and aging, and maternal effects on developmental origin of health and diseases (DOHaD). Placenta plays key roles in fetal brain development, and inadequate placental support can impact developmental process of the brain that increases risk of brain diseases in adult life. Behura lab performs both wet-lab and computational research to study regulation of the placental adaptive functions that safeguard fetal brain development. A long-term goal of the lab is to dissect the mechanisms of how these early-life perturbations impact brain health and disease later in life particularly during aging. Behura is also affiliated with the University of Missouri Institute for Data Science and Informatics, and the Interdisciplinary Neuroscience Program that helps him perform interdisciplinary research in collaboration with other faculty members.

Dan Bergstralh, PhD

Associate Professor, Division of Biological Sciences

Epithelial Tissue Architecture

Epithelia are the most common tissue type in animals. They can be found at organ boundaries, where they perform functions including absorption (the intestine), secretion (glands), filtration (kidneys), and gas exchange (the lungs). Epithelia are typically organized into sheets of cells that are one-cell thick, and our lab aims to understand how these sheets develop and are maintained. Epithelia are the most common source of carcinomas (solid tumors) and a hallmark of these cancers is a loss of the architecture and organization of their epithelial origin.

The Finegan Bergstralh Lab is currently working on two problems. 1) How do epithelial cells figure out the right direction in which to divide? 2) What happens when they don’t? These questions sit at the intersection of basic cell and developmental biology, biomedical research, and the physical sciences, so we take an interdisciplinary approach to answering them; our lab members come from several scientific backgrounds and use a range of techniques that includes traditional genetics, protein biochemistry, advanced light microscopy, and computational modelling.

Ramji Bhandari, PhD

Associate Professor, Division of Biological Sciences

Environmental Impact and Epigenetics

Dr. Bhandari is currently an Associate Professor in the Division of Biological Sciences in the Division of Biological Sciences at the University of Missouri Columbia. Before joining MU, he was an Associate Professor at the University of North Carolina at Greensboro. He is a reproductive biologist by education and environmental health scientist and epigeneticist by training. His research group investigates how gene-environment interactions lead to reproductive and metabolic diseases within the gut-liver-gonad axis. They use chemicals to which humans are exposed as environment, epigenetic mechanisms as drivers, and altered health outcomes, mainly reproductive and metabolic health, as phenotypic traits. They take comparative, molecular, cellular, and bioinformatics approaches and in vitro 3D human cell co-culture and in vivo animal models (fish and rodents) in research. Using advanced research tools, including next-generation whole genome and epigenome sequencing, artificial intelligence, transgenesis, and CRISPR-Cas9/dCas9-mediated genome/epigenome editing, they explore mechanisms underlying environmental exposure-induced altered health outcomes in the gut-liver-gonad axis in the exposed generations and their unexposed offspring in subsequent generations. Their research will lead to the development of diagnostic and predictive biomarkers for environmental health and disease. Dr. Bhandari has been supported by funding from the National Institutes of Health, the U.S. Geological Survey, the University of Missouri, and the University of North Carolina as a principal investigator. He is developing research projects in collaboration at the national and international levels as an MPI and co-PI. He has published three book chapters and 56 peer-reviewed articles. Several manuscripts are currently under peer review. He serves on several local, domestic, and international committees in various capacities, federal grant review panels, and journal editorial boards.

The standard of care in urogynecology is rapidly changing as new research is published. Fortunately for mid-Missouri women, much of that research is completed by Foster and his team of physicians, advanced practice nurses and basic science researchers — including the new standard for using antibiotics after urinary incontinence surgery. Dr. Foster also seeks to impact care through involvement in positions of national leadership. He currently serves as treasurer of the American Urogynecologic Society, the nation’s flagship organization for doctors committed to helping women with pelvic symptoms adversely impacting quality of life.

Rodney Geisert, PhD

Professor, Division of Animal Sciences

Reproductive Physiology

The long term research goal of my research has focused on elucidating the expression of genes involved with regulation of early conceptus development and uterine function. My research described and identified the cellular and molecular processes involved with rapid trophoblastic elongation of pig conceptuses during early gestation. Research has defined the role of conceptus estrogen secretion in establishment and maintenance of pregnancy in the pig and the cause of embryonic loss following exposure to exogenous estrogens during the first week of pregnancy. My laboratory’s research has established that specific cellular changes in progesterone and estrogen receptors are involved with critical events in uterine secretion and embryonic development and placental attachment in the pig. We demonstrated that PR in the uterine epithelium disappeared after Day 10 of the estrous cycle and pregnancy. With the loss of epithelial PR, an increase in ER occurs which can be activated through conceptus release of estrogen during the period of rapid trophoblastic elongation. Conceptus elongation and estrogen release are both essential for maintenance of pregnancy in the pig. Although conceptus estrogen synthesis and release has clearly implicated in maternal recognition of pregnancy in the pig by others, we were the first to indicate the need for two phases of conceptus estrogen secretion to establishment of pregnancy to term in sows.

Jonathan Green, PhD

Associate Professor, Department of Animal Sciences

Reproductive Physiology and Molecular Biology

The emphasis of the Green lab is to characterize some of the interactions that take place between the ungulate conceptus/placenta and the maternal system. Some of these studies have been directed toward examining global changes in mRNA expression patterns throughout development by using high-throughput sequencing methods. Other projects are more focused; they involve characterization of certain peptidase and peptidase inhibitor gene families produced by the placenta and the uterine endometrium in livestock. A peptidase gene family of particular interest is the pregnancy associated glycoprotein (PAG) family. The PAGs are a particularly large grouping of genes (dozens have been described within ruminant species). They were initially identified as antigens circulating in the sera of pregnant cows. They are also known to accumulate at the placenta-uterine interface. The PAGs are related to aspartic peptidases although some contain mutations at their catalytic centers that render them unable to function as peptidases. Much of the laboratory’s work on these proteins involves optimizing assays for their detection in the blood and milk of pregnant cattle. Other studies are focused on understanding the functional role that these proteins are playing during the establishment and maintenance of pregnancy in domestic ungulates.

Mark Hunter, MD

Associate Professor, Department of OB/GYN & Women’s Health

Director, Division of Gynecologic Oncology

Gynecologic Oncology, Obstetrics and Gynecology

Dr. Hunter specializes in gynecologic oncology. With nearly twenty years in practice, he has expertise in the diagnosis and treatment of ovarian, uterine, cervical, vaginal and vulvar cancers. In addition to his clinical practice, Hunter also works to advance medical technology. Many women who develop uterine cancer require a hysterectomy, a removal of the uterus. Traditionally, the surgery leaves a large scar and results in several weeks’ recovery time. Dr. Hunter has developed a prototype surgical device that would allow hysterectomies to be performed less invasively. Dr. Hunter has also been an early adopter of new medical innovations. For many of his cancer patients, he operates using the da Vinci Surgical System. This advanced device decreases incision size and reduces complications — in many cases, enabling the patient to go home the same day.

Rong Li, PhD

Assistant Research Professor, Department of OB/GYN & Women’s Health

Uterine Biology, Transcriptional Factor Regulation, Uterine Receptivity During Endometriosis

Dr. Rong Li, PhD’s research focuses on uterine biology during physiological and pathological conditions. During natural pregnancy, Dr. Li identified the critical roles of TRIM28, acting as a PGR co-regulator, to modulate the uterine biology both in cultured human endometrial stromal cells and in mouse models. Meanwhile, Dr. Li discovered epithelial PGR can regulate the uterine receptivity through LIF expression at glandular epithelium and FOXO1 nuclear localization at luminal epithelium. At this time, she is researching endometriosis associated uterine receptivity defects using the mouse endometriosis model established by Dr. Jae Wook Jeong. Dr. Li plans to conduct the novel technology scRNA-seq and spatial transcriptome to identify the spatial and cellular changes in the ectopic and eutopic uterus during endometriosis. These results may answer the important questions in the field such as “how ectopic endometrial lesions affect the eutopic uterus” and “ how the changes in the eutopic uterus lead to infertility”.

Matthew Lucy, PhD

Professor, Division of Animal Science

Molecular Endocrinology

Dr. Matt Lucy is known for his work on the reproductive physiology of high-producing dairy cows. The research program examines the physiological processes regulating fertility in dairy cows and explores practical methods to restore fertility in infertile animals. An important focus is early embryonic loss; one of the most-pressing reproductive problems facing the dairy industry today. Uterine disease early postpartum is an important factor associated with early embryonic loss. His current research, therefore, examines mechanisms through which early postpartum disease can imprint uterine tissue and reduce uterine receptivity long-term. Studies in the laboratory range from basic (cell culture, bulk RNA-seq, single cell sequencing, spatial transcriptomics, etc.) to applied (whole animal field trials).

Assistant Professor in Beef Reproduction, Extension & Research, Division of Animal Science

Cellular and Molecular Processes Controlling Reproduction

The emphasis of my research program is to understand and manipulate the endocrine, cellular and molecular processes controlling the reproductive tract function of cattle to optimize the chances of conception after a given service. My ultimate goal is to produce more kilograms of calves per unit of cow that enters the beef production system.

Our laboratory conducts studies on the topics of hormonal control of the estrous cycle and early embryonic losses in beef cattle. Specifically, we investigate progesterone-based strategies to improve efficiency of estrous synchronization programs for beef cows, embryo-maternal communication, and new fertility-promoting molecules. The research studies involve use of steroid assays, ultrasound, molecular techniques, and omics approaches. Our laboratory is also committed to promoting the use of reproductive biotechnologies in cow-calf operations.

Amanda Patterson, PhD

Assistant Professor, Department of OB/GYN & Women’s Health and Division of Animal Sciences

Mechanisms of Uterine Repair, Uterine Stem Cells, Uterine Fibroids, Cancer Stem Cells

Research in the Patterson lab is focused on understanding mechanisms of uterine repair in health and disease. During pregnancy, the uterus is drastically remodeled to accommodate an embryo/fetus, and following parturition, the tissue must be repaired to allow for subsequent pregnancies. The repair process includes regeneration of the endometrium and likely involves multiple mechanisms including stem cells. We are interested in understanding how stem cells function in the repair process, what regulates their activity and what happens when they are mutated or not properly regulated. When stem cells and other mechanisms of uterine repair go awry, they may contribute to diseases such as endometriosis and endometrial cancer, and we want to understand how this happens so better diagnostics and therapeutics can be developed.

Randall Prather, PhD

Curators’ Distinguished Professor, Division of Animal Sciences

Director of the National Swine Resource and Research Center

Reproductive Physiology & Molecular Biology, Transgenic Pigs

Our laboratory’s research is focused on early embryo development in the pig. There is a 30% loss of potential conceptuses during the first month of development. We hope that by describing the cellular and molecular program of events that occur during development of the preimplantation pig embryo, the root causes of these losses can be identified and steps can be taken to reduce them. To that end we began by transcript profiling of reproductive tissues in pigs and cattle. Since then we have adopted deep sequencing technologies to identify both transcripts and methylated regions of the genome that are unique to different stages of embryogenesis. Along the way we used that information to improve systems of in vitro embryo production and further develop technology to mature oocytes, to activate oocytes, to in vitro fertilize oocytes, to culture oocytes and embryos, and to perform embryo transfer.

Pathophysiology of uterine diseases

Md Saidur Rahman received his D.V.M. and master’s degrees from Bangladesh Agricultural University and Ph.D. from Chung-Ang University in Korea. While a research professor and postdoctoral researcher at Chung-Ang University he investigated how environmental factors interact with the genome and proteome to shape phenotypic variations and diseases. He was particularly interested in studying Endocrine Disruptors’ (EDCs)’ impact of EDCs on reproduction and how reducing their exposures may limit negative health outcomes. He joined Mizzou’s Department of Obstetrics, Gynecology and Women’s Health as a faculty member in January 2023. His current research at Mizzou is devoted to studying the molecular mechanisms that regulate the pathophysiology of uterine diseases. His focus is on uterine biology, the development of therapeutic strategies for endometriosis, and the clinical management of endometrial cancer recurrence. He seeks to apply new techniques to reproductive research, including high-resolution imaging systems and engineered animal models that are phenotypically relevant to humans and non-human primates.

Current research areas include: the biological role of endometrial glands in uterine function using sheep and mouse models; the biological roles of exosomes in conceptus elongation and uterine interactions during early pregnancy in sheep; the genetic regulation of postnatal uterine development and function using mouse models; the physiological roles of Hydroxysteroid (11-Beta) Dehydrogenases and Cortisol during early pregnancy in sheep; improving the fertility of dairy cattle using translational genomics; reducing embryo mortality through improved understanding of embryo maternal communication in beef cattle; and, a systems biology approach to understand endometrial receptivity and pregnancy loss in beef cattle

R. Michael Roberts, PhD

Curators’ Distinguished Professor, Division of Animal Sciences

Reproductive and Developmental Biology

R Michael Roberts is a Curators’ Distinguished Professor at the University of Missouri, with appointments in Animal Sciences, Biochemistry and Veterinary Pathobiology. He is currently an investigator in the University of Missouri, Christopher S Bond Life Sciences Center. He gained his B.A. and D.Phil. in Plant Sciences from Oxford University, England, but since the mid 1970s has worked primarily as a reproductive biologist. Roberts’ is best known for his work on uterine secretions, and particularly the iron-binding acid phosphatase, uteroferrin, in the pig, and on how the early embryo signals its presence to the mother in ruminant species through the production of small proteins called interferons. More recently, Roberts has been studying the specification of trophoblast as it emerges from pluripotent precursor cells and the role of maternal diet in regulating the sex of her offspring. His work is supported primarily through Federal Agencies such as the National Institutes of Health (NIH) and the United States Department of Agriculture (USDA). Currently, Dr. Roberts’ attention is on finding the causes of pre-eclampsia and the effects of the Zika virus on human pregnancy.

Cheryl Rosenfeld, DVM, PhD

Professor, Division of Biomedical Sciences

Environmental Impact and Development

Dr. Rosenfeld specializes in studying the effects of maternal diet on offspring, exploring how the in-utero environment can shape risks for later disease. Her research with mice has yielded major breakthroughs. She has determined that an energy-rich maternal diet will result in more male mouse pups, while a restricted-calorie diet produces daughters more frequently. She also established a relationship between a certain hair-coat color and obesity and diabetes in mice. Most recently, the Rosenfeld lab has identified spatial learning disabilities in male deer mice whose mothers consumed a diet supplemented with bisphenol A, (BPA), a known endocrine disruptor and a common pollutant. This disability is expected to hinder the males in navigating to find mates; the finding has implications for deer mice populations exposed to BPA in the wild.

Professor, Division of Animal Sciences

Semen Analysis, Sperm Function, Fertilization

Since the early 90’s, Peter has studied mammalian gametogenesis, fertilization, and pre-implantation embryonic development with special emphasis on the gamete and zygotic ubiquitin-proteasome system (UPS). He was the first to describe the role of UPS in the regulation of mitochondrial inheritance and introduced a novel concept of extracellular UPS, which has been validated in reproduction and outside the reproductive biology field. In particular, Peter demonstrated the importance of sperm borne proteasomes for mammalian fertilization and the role of UPS in epididymal sperm quality control, a mechanism relevant to male fertility evaluation in livestock, and the diagnosis and treatment of human male fertility. Peter’s collaborative research on the biogenesis and post-fertilization processing of sperm head perinuclear theca influenced the optimization and safeguarding of assisted reproductive technologies/therapies such as in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI). Other notable collaborations include the development of transgenic pig model for the study of 26S proteasome and work on rodent model of human endometriosis. Recently, the Sutovsky laboratory has also been focusing on biomarker-based flow cytometric semen analysis and semen nanopurification aimed at improving conception rates in livestock artificial insemination (AI).
