Abstract Peroxisome proliferator-activated receptor gamma coactivator 1α (PGC-1α) is a master transcriptional coactivator responsible for regulating cellular energy metabolism and mitochondrial biogenesis across high-energy tissues such as the heart, skeletal muscle, and brown adipose tissue. To orchestrate its regulatory functions, PGC-1α interacts with a diverse array of transcription factors such as peroxisome proliferator-activated receptors (PPARs), estrogen-related receptors (ERRs), and nu
