One of the major healthcare issues found almost worldwide, especially in the United States, is the obesity epidemic. Obesity is known to have deleterious effects on many body/organ systems. C1q TNF-related protein-3 (CTRP3) is effective at preventing high-fat diet-induced fatty liver. With these two factors taken into consideration, this study explores the possible effects of a high caloric diet on the muscle wall of the uterus, i.e., the myometrium, and how over-expression of CTRP3 may modify those effects. We hypothesize that consumption of excessive amounts of fat and sugar will have detrimental effects on the dual layers of the mouse myometrium. For this study, 17 mice were divided into 4 treatment groups: wild type/low fat diet, wild type/high fat diet, CTRP3-overexpressing/low fat diet, and CTRP3-overexpressing/high fat diet. The mice were placed on their respective diets at 7 weeks of age with a feeding duration of 12 weeks. At the conclusion of the feeding protocol, the female reproductive tissues were harvested and fixed in 4% paraformaldehyde and subsequently paraffin embedded. The uterine horns of each mouse were painstakingly paraffin embedded in a vertical position so that cross sections of the uterus could be obtained and measured. These 4ยต sections were stained using standard H&E staining techniques and visualized under light microscopy. A randomization grid was utilized to determine measurement locations on the tissue. For each animal, 15 measurements were made of the outer longitudinal layer of the uterine horn, as well as 15 measurements of the inner circular layer, and 15 measurements of the thickness of the two layers combined. Two-way ANOVA was used to determine if any changes seen were statistically significant. At the time of the writing of this abstract, no appreciable differences have been found between the treatment groups, although there will be more data and final statistics completed before the presentation of our findings.
