分子时钟REV-ERBα是调节肺损伤的核心,REV-ERBα丰度降低介导对促纤维化损伤的敏感性并加剧纤维化进展。在这项研究中,我们确定REV-ERBα在博莱霉素和甲型流感病毒(IAV)诱导的纤维化中的作用。博莱霉素暴露降低了REV-ERBα的丰度,夜间给予博莱霉素的小鼠显示肺纤维化加重。Rev-erbα激动剂(SR9009)治疗可预防博莱霉素诱导的小鼠胶原蛋白过度表达。与WT感染的小鼠相比,感染IAV的Rev-erbα全杂合子(Rev-erbα Het)小鼠的胶原和赖氨酰氧化酶水平升高。此外,在人肺成纤维细胞中,Rev-erbα激动剂(GSK 4112)防止TGFβ诱导的胶原和赖氨酰氧化酶过度表达,而Rev-erbα拮抗剂加剧了这种过度表达。总之,这些结果表明,REV-ERBα的缺失通过促进胶原和赖氨酰氧化酶表达而加剧了纤维化反应,而Rev-erbα激动剂则可抑制肺纤维化的发生。本研究为Rev-erbα激动剂治疗肺纤维化提供了可能。分子钟REV-ERBα调节纤维化期间的肺损伤,但REV-ERBα在纤维化发生中的作用仍不清楚。在这里,作者表明,REV-ERBα在纤维化过程中与赖氨酰氧化酶-胶原轴相互作用,并证明了Rev-erbα激动剂对肺纤维化的治疗潜力。
Molecular clock REV-ERBα is central to regulating lung injuries, and decreased REV-ERBα abundance mediates sensitivity to pro-fibrotic insults and exacerbates fibrotic progression. In this study, we determine the role of REV-ERBα in fibrogenesis induced by bleomycin and Influenza A virus (IAV). Bleomycin exposure decreases the abundance of REV-ERBα, and mice dosed with bleomycin at night display exacerbated lung fibrogenesis. Rev-erbα agonist (SR9009) treatment prevents bleomycin induced collagen overexpression in mice. Rev-erbα global heterozygous (Rev-erbα Het) mice infected with IAV showed augmented levels of collagens and lysyl oxidases compared with WT-infected mice. Furthermore, Rev-erbα agonist (GSK4112) prevents collagen and lysyl oxidase overexpression induced by TGFβ in human lung fibroblasts, whereas the Rev-erbα antagonist exacerbates it. Overall, these results indicate that loss of REV-ERBα exacerbates the fibrotic responses by promoting collagen and lysyl oxidase expression, whereas Rev-erbα agonist prevents it. This study provides the potential of Rev-erbα agonists in the treatment of pulmonary fibrosis. The molecular clock REV-ERBα regulates lung injury during fibrosis, but the role of REV-ERBα in fibrogenesis remains unknown. Here, the authors show that REV-ERBα interacts with the lysyl oxidase-collagen axis during fibrogenesis and demonstrate the therapeutic potential of Rev-erbα agonist against lung fibrosis.
