Although previous studies have found that Mir802 was up-regulated in the adipose tissue during obesity (Zhang et al., 2020; Kornfeld et al., 2013; Ge et al., 2022; Goga et al., 2021), the function of Mir802 was focused on cancers (Gao et al., 2021), liver (Seok et al., 2021; Ni et al., 2021), small intestine (Goga et al., 2021), and pancreas (Ge et al., 2022). The gene discussed is MIR802; the disease is obesity due to melanocortin 4 receptor deficiency.
