Abstract:

Hypertrophic scar (HS) is a condition characterized by excessive synthesis and deposition of collagen. There are many clinical methods to alleviate HS, but most of them are accompanied by many complications. To investigate the effects ofβ-Elemene, extracted from the ginger family plant Wenyujin, on human hypertrophic scar fibroblast (hHSFs). Cultured hHSFs and human normal fibroblasts, observed the effect of β-Elemene on apoptosis, extracellular matrix, and endoplasmic reticulum stress (ERS) by western blot, Real Time-PolymeraseChain Reaction (RT-PCR), and flow cytometry. Based on our findings, it is clear that β-Elemene could inhibit the expression of α-smooth muscle actin (α-SMA), collagen I, and fibronectin, reduced collagen deposition. Further studies had found that β-Elemene could increase the expression of ERS-related proteins CHOP and Calnexin in a dose-dependent manner, thereby promoting the aggregation of cleaved-caspase-3 and inducing hHSFs to undergo poptosis. This process may depend on the regulation of P53. The results of our study indicates that β-Elemene induced hHSFs to undergo apoptosis though ERS pathway in a P53-dependent manner, which means that our research provided a new strategy for the development of drugs for the treatment of HS.
