CASP3 and Parkinson disease: The expression level of cleaved caspase-3 (p < 0.01) was observed to be elevated in the SN of PD mice whereas attenuated expression of cleaved caspase-3 (p < 0.05) was observed in the drug-treated group, which shows the antiapoptotic property of CGA in the parkinsonian mouse model (Figure 4(c)).
