ABSTRACT
Peroxisome proliferator-activated receptor (PPAR) is a transcriptional coactivator that binds to a diverse range of transcription factors. PPAR coactivator 1 (PGC-1) coactivators possess an extensive range of biological effects in different tissues, and play a key part in the regulation of the oxidative metabolism, consequently modulating the production of reactive oxygen species, autophagy, and mitochondrial biogenesis. Owing to these findings, a large body of studies, aiming to establish the role of PGC-1 in the neuromuscular system, has shown that PGC-1 could be a promising target for therapies targeting neuromuscular diseases. Among these, some evidence has shown that various signaling pathways linked to PGC-1 are deregulated in muscular dystrophy, leading to a reduced capacity for mitochondrial oxidative phosphorylation and increased reactive oxygen species (ROS) production. In the light of these results, any intervention aimed at activating PGC-1 could contribute towards ameliorating the progression of muscular dystrophies. PGC-1 is influenced by different patho-physiological/pharmacological stimuli. Natural products have been reported to display modulatory effects on PPAR activation with fewer side effects in comparison to synthetic drugs. Taken together, this review summarizes the current knowledge on Duchenne muscular dystrophy, focusing on the potential effects of natural compounds, acting as regulators of PGC-1.
ABSTRACT
Inflammation plays a pivotal role in atherogenesis. In addition to being a potent predictive and prognostic marker for major cardiovascular events, recent evidence indicates that C-reactive protein (CRP) might directly promote atherogenesis by exerting direct effects on vascular cells. Thus, CRP will become important novel pharmaceutical targets for the treatment of atherosclerosis. This review presents an overview of the current knowledge about the pathological role of CRP in atherosclerosis initiation and progression.
