MED1 and obesity due to melanocortin 4 receptor deficiency: Using Med1 ChIP-seq data from ChIP-Atlas (https://chip-atlas.org/), we noted that among the 74 genes upregulated in obesity-breast cancer signature, 48 genes were putative targets for Med1 recruitment (Fig. 3C, Supplementary Table 1), indicating its importance in obesity-breast cancer connection.
