1. How does incremental load training regulate TGF-β1/TAK1/MKK3/p38MAPK signaling pathway?
Incremental load training improves renal fibrosis by regulating the TGF-β1/TAK1/MKK3/p38MAPK signaling pathway. This pathway plays a crucial role in the development of renal fibrosis, a condition characterized by the excessive accumulation of extracellular matrix proteins in the kidneys. Incremental load training has been shown to modulate this signaling pathway, leading to the activation of autophagy and subsequent reduction in renal fibrosis. The study conducted by Chuncha Bao et al. (2019) demonstrated that incremental load training in aged mice resulted in the regulation of the TGF-β1/TAK1/MKK3/p38MAPK signaling pathway, ultimately improving renal fibrosis. This finding suggests that incremental load training can be a potential therapeutic approach for the treatment of renal fibrosis in aged individuals.
