Fig. 1From: Inhibition of lung cancer cells and Ras/Raf/MEK/ERK signal transduction by ectonucleoside triphosphate phosphohydrolase-7 (ENTPD7)Expression characteristics of ectonucleoside triphosphate phosphohydrolase-7 (ENTPD7) (a) The Cancer Genome Atlas (TCGA) was used to determine the differential mRNA expression of ENTPD7 in patients at different lung cancer TNM stages. b Comparison of survival rates of patients at different ENTPD7 expression levels. c, d Streptavidin-perosidase (SP) staining was performed to detect ENTPD7 protein in lung tissues (n = 44) and adjacent tissues (n = 44). e, f Quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot were performed to determine ENTPD7 mRNA and protein expression levels in different lung cells lines. All PCR reactions and protein assays were performed in triplicate. GAPDH was used as an internal control. *P < 0.05, **P < 0.01, versus BEAS2B groupBack to article page
