CircC3P1 attenuated pro-inflammatory cytokine production and cell apoptosis in acute lung injury induced by sepsis through modulating miR-21.

ABSTRACT: Acute lung injury (ALI) induced by sepsis is characterized by an inflammatory process related to the up-regulation of inflammatory cytokines and chemokines. In the present study, we explored the role of circC3P1 in sepsis-induced ALI in vitro and in vivo. The caecal ligation and puncture (CLP)-induced sepsis model was established through CLP surgery. Forty adult male C57BL/6 mice were randomly assigned into sham, CLP, CLP + vector and CLP + circC3P1 (each n = 10). Primary murine pulmonary microvascular endothelial cells (MPVECs) were transfected with circC3P1 or empty vector 24 hours prior to LPS treatment via Lipofectamine 2000. The expressions of circC3P1, tumour necrosis factor-α (TNF-α), interleukin-6 (IL-6) and IL-1β were evaluated after 6-h LPS treatment. Cell apoptosis was evaluated
