The early response of αB-crystallin to a single bout of aerobic exercise in mouse skeletal muscles depends upon fiber oxidative features
2019
Besides its substantial role in eye lens, αB-crystallin (HSPB5) retains fundamental function in striated muscle during physiological or pathological modifications. In this study, we aimed to analyse the cellular and molecular factors driving the functional response of HSPB5 protein in different muscles from mice subjected to an acute bout of non-damaging endurance exercise or in C2C12 myocytes upon exposure to pro-oxidant environment, chosen as “in vivo” and “in vitro” models of a physiological stressing conditions, respectively.To this end, red (GR) and white gastrocnemius (GW), as sources of slow-oxidative and fast-glycolytic/oxidative fibers, as well as the soleus (SOL), mainly composed …
Role of the small heat shock protein alphaB-crystallin in pulmonary fibrosis and its implication in the signaling pathway of the Transforming Growth …
2013
Idiopathic pulmonary fibrosis (IPF) has no effective current treatment. It is characterized by a sub-pleural onset and the presence of myofibroblasts, responsible for the excessive extracellular matrix synthesis. Transforming Growth Factor (TGF)-β1 is considered as the major profibrotic cytokine. Its signaling pathway occurs through the Smads proteins, including Smad4. TGF-β1 allows the differentiation of lung fibroblasts and epithelial and mesothelial cells into myofibroblasts. AB-crystallin is a small heat shock protein overexpressed in liver, renal and vascular fibrosis and can be induced by TGF-β1. In this study, we assessed the role of αB-crystallin in pleural and pulmonary fibrosis. W…
