Web4 apr. 2024 · Gene expression of peroxisome proliferator-activated receptor-gamma coactivator 1alpha (PGC-1alpha), which is a master regulator of mitochondrial biogenesis, was decreased in the hippocamus of gonadectomized rats. Significant overexpression of PGC1-alpha in the stress-subjected rats. Web7 sep. 2024 · PGC-1 α has been reported to activate the production of VEGF through the estrogen-related receptor α - (ERR α -) dependent pathway [ 98 ]. PGC-1 α was shown to regulate HIF-1 α activity. Increased PGC-1 α expression enhances oxygen consumption, resulting in decreased local oxygen tension and increased HIF-1 α stability [ 99 ].

WebPGC1a and PGC1b are tissue-specific transcrip-tional coactivators of the PPAR-c coactivator-1 fam-ily, as it has been shown in goldfish, among others [28]. Both factors have been implicated in the regula-tion of mitochondrial biogenesis. Recently, Necdin has been identified as a novel regulator of PGC1a in stud- Web1 mrt. 2006 · The interaction of PGC-1α with its cognate transcription factor targets is shown linked to specific organ systems. For example, PGC-1α coactivates members of the PPAR nuclear receptor transcription factor family, to activate the expression of genes involved in mitochondrial fatty acid oxidation.
WebCREB acts through calcium and the protein kinase A pathway in the corticostriatal region (a component of the central nervous system that plays a major role in learning). This process is mediated by glutamate and DA signals. Many genes that are responsible for the generation and phosphorylation of CREB are dependent on NMDA and DA D1 receptors.
