FTO and obesity due to melanocortin 4 receptor deficiency: To visualize the relative expression profile of these proteins coding genes (expanded white and brown gene-sets) in adipocytes, we used transcriptional data from our recent study [25] on ex vivo differentiated primary human subcutaneous (SC) and deep neck (DN) brown adipocytes, with or without FTO rs1421085 intronic SNP (obesity-risk allele).
