Johnnie Ray Cox Term Chair in Biomedical Research
Lab rotations are currently available in this lab. Please contact Dr. Kim.
My research for almost 30 years has focused on obesity, insulin resistance, and type 2 diabetes and explores the molecular link between inflammation and insulin resistance using transgenic mice with elegant in vivo metabolic experiments and molecular approaches. My research also investigates the role of inflammation and altered metabolism in diabetic heart disease.

Rotation Projects Our rotation projects are in the area of diabetes and obesity, and we are interested in basic mechanisms of cell proliferation, differentiation and communication. Diabetes is highly correlated with obesity, but why obesity causes disease in some humans and not others is not understood. Amazingly, we still don’t understand how adipose tissue grows in human adults. A better understanding of this fascinating process can give us insight into basic mechanisms of cell growth, differentiation and communication, as well as mechanisms of disease, not only diabetes but also cancer and developmental defects. During your rotation, you will work on an important piece of a larger project, that has a well-defined outcome. Thus, your successful completion of the rotation project will allow you to be included at the time of publication of the work. Project 1: Adipose tissue is not only formed by adipocytes, but by other cells such as endothelial, mural and immune cells. Also, there are multiple kinds of adipocytes with different functions. We have recently developed conditions to develop adipose tissue from humans in-vitro (adipose tissue “organoids”). From this tissue we have been able to separated single cells, and find that they grow into different kinds of clones. We are now conducting RNAseq on >300 of those clones, to determine how many cell types exist in human adipose tissue, and what their roles are. In this rotation, you will be able to analyze RNAseq data to define what genes characterize these cells, and you will use virus transduction to create immortalized cells for further study. Project 2: Adipose tissue has many functions besides storing and releasing lipids. It also has to coordinate metabolism in the whole body. We have found that human “beige” adipose tissue, which is found in people who are metabolically healthy, expresses genes for secreted factors that communicate with the immune system and the brain. These include IL-33 and enkephalins. In this project you will knockout these genes, and investigate whether this changes the function of adipose tissue when we implant it into immune compromised mice.

Thus the ability to direct gene editing in adipocytes in vivo has great potential in developing therapeutic strategies for obesity, type 2 diabetes and cardiovascular complications. Alternatively, an ex vivo approach is also feasible since adipose cells can be genetically altered in vitro prior to implantation into mice with beneficial effects. Such projects are designed to be performed in collaboration with other Czech lab members with the goal of specifically deleting or editing genes in adipose depots that drive increases in fatty acid oxidation, energy expenditure and systemic metabolic activity. Exciting preliminary data at the “proof of principle” stage has been achieved and this project is designed to focus on specific genes of high interest for therapeutics. Signaling by the lipogenesis pathway through Acetyl CoA: A major function of adipocytes is to store calories as triglyceride, in part through the process of fatty acid synthesis (lipogenesis). This metabolic pathway involves a number of metabolites including Acetyl CoA, which is also a substrate for acetylation reactions that modify proteins such as histones. Thus metabolic flux through adipocyte lipogenesis may also function as a signaling pathway to the nucleus to modulate transcription via levels of Acetyl CoA that accumulate during this process. This rotation project is designed to test this idea at the molecular level by monitoring histone acetylations and resultant transcriptional events during changes in Acetyl CoA levels caused by altering physiological conditions such as exercise, obesity and diabetes. If this concept is correct, the project could lead to developing therapeutic strategies for metabolic disease based on targeting lipogenic enzymes.

Potential Rotations for Students Characterize the Leydig cell phenotype of different KO and transgenic models of specific genes relevant to reproductive development to determine the role of these genes in Leydig cell development: i.e. GPR54, androgen receptor, etc. Examine the mechanisms underlying the inhibitory effects of dioxin on Leydig cell steroidogenesis and investigate the developmental basis of this. Investigate the role of MIS in the development of Leydig cell tumors. Examine MIS signaling in Leydig cells.
