PG - 568894 LID - 10.3389/fcell.2020.568894 [doi] LID - 568894 AB - Tendinopathy is a common musculoskeletal disorder that mainly affects athletes and people of older age. Tumor necrosis factor-alpha (TNF-alpha) plays an important role in initiating tendinopathy. Tectorigenin, an extract component of Belam-canda Chinesis, possesses anti-inflammatory and anti-apoptosis activity. The present study was established to investigate the role of tectorigenin against the pathogenetic effects of TNF-alpha on tendon-derived stem cells (TDSCs) in vivo and in vitro. The findings indicated that TNF-alpha is able to induce TDSC inflammation, apoptosis, and ossification, as well as activate nuclear factor-kappa B and mitogen-activated protein kinase (MAPK). Furthermore, the results confirmed that tectorigenin is able to inhibit the TNF-alpha-induced inflammation, apoptosis, and ossification. Tectorigenin treatment decreases activation of NF-kappa B and MAPK signaling in TDSCs. Tectorigenin ameliorates tendinopathy in the in vivo rat model. Thus, these data reveal that tectorigenin can serve as a potential treatment for tendinopathy. CI - Copyright (c) 2020 Moqbel, Xu, Chen, Xu, He, Wu, Ma, Ran, Wu and Xiong.
