The level of Bcl-w and HIF-1α expression increases in tissues and plasma of lung cancer patients

(A) Expression of Bcl-w and HIF-1α was confirmed by immunohistochemistry (IHC) staining in tissues of lung cancer patients (scale bars, 200 μm). (B) Bcl-w mRNA levels in the plasma of lung cancer patients were detected by quantitative real-time PCR: normal (n = 8) versus lung cancer (n = 8). (C) Levels of HIF-1α mRNA in the plasma of lung cancer patients were detected by quantitative real-time PCR: normal (n = 12) versus lung cancer (n = 13). The data are presented as mean ± SD. ∗p < 0.05. Student’s t test.
