- MicroRNA-221-3p (miR-221-3p) impacts lipid metabolism and adipocyte differentiation, showing that overexpression inhibits fat storage and key adipogenic genes, while its inhibitor promotes fat accumulation.
- Global lipid analysis revealed that miR-221-3p overexpression disrupts fat synthesis and alters lipid profiles by increasing ceramides and sphingomyelins while decreasing diacylglycerols.
- Additionally, high levels of miR-221-3p in breast cancer patients' adipose tissue suggest it may enhance cancer cell growth and invasion, indicating a link between fat metabolism and cancer development.
