BCL2 and Parkinson disease: The bcl-2 mRNA expression was elevated (Figures 2(a) and 2(b)) and caspase-3 mRNA expression was decreased (Figures 2(c) and 2(d)) after the PD cell model was processed with CM-CUR, CM-MSC, and CUR for 48 h and showed statistically significant difference compared with the model group (∗∗p < 0.01).
