Figure Lengend Snippet: SH2B1 deficiency refrained glycolysis of NSCLC cells. NSCLC cells were transfected with sh‐SH2B1#2 or SH2B1 overexpression plasmid for 48 h. (A–D) Glucose uptake (A), lactate production (B), ECAR (C), and OCR (D) of NSCLC cells were detected by commercial kits, respectively. (E) Protein abundance of HK2, GLUT1, PDK1, ENO1, and LDHA was assessed by western blotting. (F) GLUT1 expression in NSCLC tissues and paired normal lung tissues was evaluated by immunohistochemical staining. Scale bar = 50 µm. (G) RT‐qPCR analysis of SH2B1 and GLUT1 mRNA levels in NSCLC and normal lung tissues ( n = 40). (H) Correlation between SH2B1 and GLUT1 expression in NSCLC tissues was analyzed by the Pearson correlation analysis ( n = 40). (I) The correlation between SH2B1/GLUT1 expression and survival of NSCLC patients was analyzed by Kaplan‐Meier plotter ( n = 40). Student's t ‐test (for G) or one‐way ANOVA followed by Tukey's test (for A–E) was adopted for statistical analysis. * p < .05, ** p < .01, and *** p < .001.
