YAP1 and obesity due to melanocortin 4 receptor deficiency: Similar to our findings, gene set enrichment analysis (GSEA) data revealed that YAP and lipid metabolism signatures were positively correlated with obese‐isolated E0771 cells than that in the chow diet group (Figure S3C, Supporting Information), suggesting that YAP and lipid metabolism may play an essential role in obesity‐associated breast tumorigenesis.
