PEBP1 and obesity due to melanocortin 4 receptor deficiency: Thirteen miRNAs previously linked to obesity were quantified, and RKIP expression was evaluated at the mRNA level and by immunohistochemistry, including phosphorylated RKIP (pRKIP).<h4>Results</h4>Of the 13 miRNAs analyzed, miR-23a-3p and miR-543 were upregulated in T2DM (p = 0.032 and p = 0.009, respectively), whereas miR-320a-3p was downregulated (p = 0.009).
