In the catalepsy test, compared with the CTRL group, the relative descent latency in the Bar test was increased in PD rats, whereas EGCG decreased the relative descent latency in the Bar test; moreover, EGCG did not increase the relative descent latency in Bar test in PD rats when CID755673 was used to inhibit the PKD1 expression and Ad-PARP-1 was used to activate the Parthanatos (Figure 2e). The gene discussed is PARP1; the disease is Parkinson disease.
