Figure 3 MaR1 increased NO concentrations and iNOS levels in THS-induced lung tissues. MaR1 or physiological saline were injected into THS-induced lung injury models. (A) The levels of NO were assessed. (B) qRT-PCR was used to measure the iNOS mRNA levels. (C) Western blot assay was adopted to assess the iNOS protein expression. ** P<0.01 versus Sham; #, ## P<0.01 versus THS+saline group. MaR1 – Maresin-1; NO – nitrogen oxide; iNOS – inducible nitric oxide synthase; THS – trauma hemorrhagic shock; qRT-PCR – quantitative real-time polymerase chain reaction; mRNA – messenger RNA.
