Targeting IL6/JAK2/STAT3 signaling for suppression of A549-F3 metastasis in vivo. a Brain metastases were determined by bioluminescence imaging. b Histogram showed incidence of brain metastasis in the different groups. c Photon flux detected from brain-metastatic focus in the different groups. d Brain metastases were determined by bioluminescence imaging. e Histogram showed incidence of brain metastasis in the different groups. f Photon flux detected from brain-metastatic focus in the different groups. g Kaplan–Meier estimates of the cumulative probability of brain metastasis among. NSCLC patients according to the level of IL6 in serum. h Kaplan–Meier survival curves of NSCLC patients with IL6 high expression and IL6 low expression. i Proposed model for IL6/JAK2/STAT3 activation in M2-microglia to promote colonization of brain-metastatic cells. Data are mean ± SD. *P < 0.05; **P < 0.01
