Research Question

"PGC-1α is known to enhance mitochondrial function and antioxidant responses, yet overexpression increased susceptibility to MPTP-induced neuronal death. This contradicts the expected neuroprotective role and challenges PGC-1α as a therapeutic target in PD. Gap type: contradiction Source paper: Pgc-1α overexpression downregulates Pitx3 and increases susceptibility to MPTP toxicity associated with decreased Bdnf. (2012, PloS one, PMID:23145024)"
