Fig. 4From: Role of A2B adenosine receptor-dependent adenosine signaling in multi-walled carbon nanotube-triggered lung fibrosis in miceCVT-6883 inhibited profibrotic mediators in MWCNT exposure mice. a RT-qPCR was performed to determine the relative mRNA level of TGF-β1 in lung tissues. b The protein levels of TGF-β1, p-Smad3, and Smad3 in lung tissues were determined using western blot. Data represented the mean ± SEM (n = 3). *p < 0.05, versus control group. #p < 0.05, versus MWCNT groupBack to article page
