Circular RNA has Circ 001372-Reduced Inflammation in Ovalbumin-Induced Asthma Through Sirt1/NFAT5 Signaling Pathway by miRNA-128-3p.

In this study, we sought to investigate the prospective role of circ 001372 in modifying inflammation in ovalbumin-induced asthma. In the vivo model of asthma, the serum of circ 001372 was reduced. Down-regulation of circ 001372 increased inflammation reaction (TNF-α, IL-1β, IL-6, and IL-18) and induced COX-2 and iNOS protein expression in vitro model through activation of NFAT5 and suppression of Sirt1. Up-regulation of circ 001372 decreased inflammation reaction (TNF-α, IL-1β, IL-6, and IL-18) in vitro model through inactivation of NFAT5 and induction of Sirt1 by miRNA-128-3p. The miRNA-128-3p lowered the effects of circ 001372 on inflammation in vitro model. The Sirt1 inhibitor reduced the effects of circ 001372 on inflammation in vitro model. Our results revealed the serum of circ 001372 against inflammation in ovalbumin-induced asthma through Sirt1/NFAT5 by miRNA-128-3p.
