PGC-1α (Peroxisome proliferator-activated receptor gamma coactivator 1-alpha) is a transcriptional coactivator that plays a crucial role in regulating cellular energy metabolism, including mitochondrial biogenesis and function. PGC-1α is also involved in various cellular processes, including cell growth, differentiation, and survival.
In some cancers (for example, certain melanomas, breast cancers, and prostate cancers), elevated levels of PGC-1α have been observed.
– Increased PGC-1α may enhance mitochondrial function and support the energetic and biosynthetic demands of tumor cells, especially under metabolic stress or during metastasis.
