Abstract or Artist's Statement

C1q TNF-related protein-3 (CTRP3) is effective at preventing high-fat diet-induced fatty liver; Recent studies have shown that overexpression of C1q TNF-related protein-3 (CTRP3) in mice fed a high alcohol diet can protect the animal from developing fatty liver disease, and therefore may be a possible treatment for alcoholic fatty liver disease (ALD). However, the possible effects of overexpression of CTRP3 on other tissue has not been widely investigated. If overexpression of CTRP3 proves to be harmful to other tissues, its use as a treatment for ALD would come into question. This study utilized kidney tissue from mice that were fed a high fat diet for 13-14 weeks. The feeding started when the mice were 7 weeks old and continued for 9 weeks. The mice were divided into 4 categories: wild-type/low fat diet, wild-type/high fat diet, transgenic/low fat diet, and transgenic/high fat diet. The kidneys were harvested and fixed in 4% paraformaldehyde and subsequently paraffin embedded. Sections were cut at 4µ and stained using three different staining techniques: standard H&E, Periodic Acid Schiff (PAS), and Masson’s Trichrome Staining. These three methods were utilized to better visualize possible effects on the tissue, i.e. changes in connective tissue deposition or basement membrane thicknesses, etc. Light microscopic examination of the tissues to date has revealed abnormalities in some of the kidney tubules in the transgenic high fat diet group. These same abnormalities have not been observed in the other treatment groups. This study is still in its early stages and much more in-depth investigation is needed to determine which of the tubules of the nephron are affected, and what this effect is. If this study confirms that overexpression of CTRP3 coupled with a high fat diet is harmful to kidney tissues, the use of CTRP3 in the treatment of ALD would require careful monitoring of the patient’s diet.
