From: TGF-β1, IL-6 and TNF-α in Bronchoalveolar Lavage Fluid: Useful Markers for Lung Cancer?
Comparison of TGF-β1, IL-6 and TNF-α levels in bronchoalveolar lavage fluid between benign and malignant groups.
The levels of TGF-β1 were significantly higher in lung cancer patients than those in benign diseases (P = 0.003, Mann-Whitney U-test) (A); no significant difference of IL-6 (P = 0.61, Student's t-test) (B) or TNF-α (P = 0.72, Student's t-test) (C) levels was found between malignant and nonmalignant groups. Horizontal lines represent the median values for TGF-β1; Horizontal lines represent the mean values for IL-6 and TNF-α.
