Program Director/Principal Investigator (Last, First, Middle): Rankin, Gary O 72these chemokines. Clinical correlations revealed a positive association with the increase inchemokines to increased presence of congestive heart failure.More samples are being analyzed to validate and confirm our findings. Validation of the biomarkerswill also be performed using cell culture studies.Aim 3: MiRNAs are 18-25 nucleotides long and regulate gene expression. These miRNAs influencethe expression of a gene by either degrading or repressing the target mRNA. This aim investigatesthe genome wide differences in miRNA profile in EF and compares them to subcutaneous fat (SF)from all patients recruited. We will also investigate if there were sex specific changes in miRNAprofile in the epicardial fat. As a preliminary study, the human miRNA microarray consisting of over88 miRNAs relevant to humans was performed on the RNA isolated from EF and SF obtained frompatients (n=8/sex). Threshold values were then used to compare miRNA expression in the EF ofeach patient. The SF samples from the respective patients were used as the control group whendetermining miRNA expression. Upon completion and initial review of the data, we found severalinteresting findings. Females had no up-regulated expression while males had 27 up-regulatedmiRNAs in EF. Females had 13 while males had 16 down-regulated miRNAs. MiR 122, MiR 196-b,MiR 302c, and MiR 210 all showed decreased expression in both males and females and remainsa cause for further study. Statistical validations of our initial findings are still to be performed.Whole genome miRNA arrays (800 miRNAs in humans) have been performed in approximately 8patients. miRNAs were isolated from both epicardial and subcutaneous fat and whole genomemiRNA was performed using the Roche 480 system. Data analysis will be performed with theassistance of the Bio-informatics core.3. Human Subjects targeted/planned enrollment and an inclusion enrollment report is attached (seeattached excel file)4.
