MicroRNAs Expressed in Visceral Adipose Tissue from Mice Fed High-Fat Diets Supplemented with Eicosapentaenoic Acid (EPA)
The goal of this subproject is to identify microRNAs (miRNAs) expressed in visceral (VIS) adipose tissue (gonadal fat from male C57BL/6 mice) and regulated by eicosapentaenoic acid (EPA). This will provide insight into microRNAs regulated by EPA and their potential role in obesity-associated inflammation. We performed small RNA-sequencing of white (VIS) adipose tissue from high-fat diet (45% kcal from fat) supplemented with EPA (45% Kcal from fat, 6.75% EPA). Using the Gunaratne Next-Generation pipeline (published in Creighton et al. 2009), miRNA expression profiles were identified. Counts of each unique read were normalized to total usable reads, and had 40 counts added. We mapped about 13.8 million sequence reads per sample to the Mus musculus genome (build mm 10). We are specifically interested in those miRNAs expressed in VIS fat from EPA-fed mice compared to HF-fed mice. Overall design: Method: We performed small RNA-sequencing of VIS fat from mice fed high-fat diet supplemented with EPA (45% Kcal from fat, 6.75% EPA). Results: Using the Gunaratne Next-Generation pipeline (published in Creighton et al. 2009), miRNA expression profiles were identified. Counts of each unique read were normalized to total usable reads, and had 40 counts added. We mapped about 13.8 million sequence reads per sample to the Mus musculus genome (build mm 10). Conclusion: Specific miRNAs are expressed in white adipose tissue from mice fed EPA-supplemented HF diets.
