Abstract:
:This study explored the effects and mechanisms of dopamine D1 receptors (DR1) activation on the apoptosis of osteosarcoma cells (OS732).The DR1 agonist SKF-38393 decreased the viability of OS732 cells and increased their rate of apoptosis, whereas the DR1 antagonist SCH-23390 abolished the effects of SKF-38393. In OS732 cells, overexpression of DR1 increased the rate of apoptosis, caspase-9 and -3 expression, and the release of cytochrome c (Cyt c), reduced Bcl-2 expression, inhibited extracellular signal-regulated kinase 1/2 (ERK1/2) phosphorylation, and induced phosphorylation of p38 mitogen-activated protein kinase (p38 MAPK) and c-Jun N-terminal kinase (JNK). These results suggest that activation of DR1 induces osteosarcoma cell apoptosis via changes to the MAPK pathway.
