Plasma TGF-β1 was up-regulated in NSCLC patients and was negatively correlated with lncRNA HAND2-AS1
ELISA data showed that plasma levels of TGF-β1 were significantly up-regulated in NSCLC patients than in healthy controls (A) (*P<0.05). Pearson’s correlation coefficient showed that plasma levels of lncRNA HAND2-AS1 and TGF-β1 were negatively correlated in NSCLC patients (B) but not in healthy controls (C).
