SREBP1c ablation also promotes a compensatory upregulation of SREBP2, leading to increased hepatic cholesterol synthesis and cholesterol accumulation, linking DNL to cholesterol metabolism [46]
Unlike MT-1 whose linear backbone and tridecapeptide length confer preferential MC1R activity, MT-IIs cyclic heptapeptide structure produces a more compact, conformationally rigid pharmacophore with enhanced affinity at the centrally expressed MC3R and MC4R subtypes alongside maintained MC1R activity and generating the distinctive multi-system pharmacological profile that encompasses skin pigmentation through MC1R, pro-sexual and pro-erectile effects through hypothalamic and limbic MC3R/MC4R activation, and anorexia and energy balance modulation through hypothalamic MC3R/MC4R

the study also conducted in the wounded rat model showed their significant anti-inflammatory, angiogenic, and folliculogenic properties, thus promoting wound regeneration and healing ability [162]
