Abstract:
:Vascular smooth muscle cell (VSMC) proliferation plays a key role in neointimal hyperplasia and restenosis. Here we report the role of the microRNA miR-142-5p and its downstream target genes on the proliferation of cultured VSMCs. miR-142-5p promoted VSMC proliferation by down-regulating B cell translocation gene 3 (BTG3). We found that BTG3 inhibited the expression of cell cycle regulatory genes and cell growth. As shown by luciferase reporter assay, miR-142-5p bound directly to the 3'-untranslated region of BTG3. Overexpression of miR-142-5p induced expression of cell cycle regulatory genes. Thus, BTG3, a novel, direct target of miR-142-5p, negatively regulates VSMC proliferation.
