A. The images (left panel) and weighs (right panel) of xenografts generated by the control cells and G9a-attenuated H1299 (compared to the control xenografts, * P < 0.05. B. Representative images for H&E and G9a, H3K9me2 and pFAK IHC staining in the xenograft tissues of the control and G9a-attenuated H1299 cancer cells (scale bar: 200 μm). C. left panel, Representative GFP images for liver metastasis (the upper of left panel) and lung metastasis (the lower of left panel) formed by the GFP-labeled control and G9a-attenuated H1299 cells. Right panel, Statistical analysis of the metastasized cells and the number of nodules in liver (the upper of right panel) and lung (the right of lower panel) (** P < 0.01, compared to the control cells). D&E. Representative images for G9a (E) proteins and pFAK (F) proteins scored as 0, 1+, 2+, 3+ in NSCLC tissues (Scale bar: 200 μm). F. Cross distribution and correlation of G9a IHC scores to pFAK IHC scores in 159 NSCLC tissues. X axis is for G9a IHC scores, Y axis is for pFAK scores. Number in dot is the sample size with various G9a and pFAK. R is the Spearman’s correlation coefficient for G9a and pFAK. G. Schematic diagram of the potential mechanisms for G9a-enhanced metastasis, modulated FAK and NF-κB signaling pathways, and related therapeutic implications in NSCLC.
