CEBPD and obesity due to melanocortin 4 receptor deficiency: This is because inhibition of DNER upregulates C/EBPd expression and keeps hAMSCs in a quiescent state, which bypasses the MCE and in turn produces more fat and larger lipid droplets, ultimately resulting in abnormal accumulation and obesity (Ponce‐de‐Leon et al. 2022; Park et al. 2010).
