Figure Lengend Snippet: Fig. 2. Stimulation of STAT3-BCL2 axis by AURKB. (A) Gene set enrichment (GSEA) data of upregulated STAT3 target genes in the H1993 PR-S2 cells. (B) Protein expressions of p-STAT3, STAT3, and GAPDH. (C) Protein expressions of p-STAT3, STAT3, p-AURKB, AURKB, and GAPDH after barasertib single or PHA665752 combination treatment of indicated drug concentration for 48 h. (D) Immunoblot analysis of the H1993 and H1993 PR-S2 cells transfected with scramble and siAURKB for 48 h. (E) and (F) The indicated protein ex pressions of the GFP and AURKB-GFP virus-infected H1993 stable cell lines and MG132 treatment for the indicated treatment time. The line graph represents the protein stability of p-STAT3. (G) and (H) RT-qPCR and immunoblotting measured the expressions of STAT3 downstream targets. (I) mRNA expression of BCL2 after treatment of 10, 100, and 1000 nM concentrations of barasertib. (J) mRNA expression levels of BCL2 and STAT3 in the scramble or siSTAT3 transfected H1993 and H1993 PR-S2 cells. (K) Protein expression of cleaved-caspase3 and BCL2 after treatment with barasertib for 48 h. The error bars represent the mean ± SEM (n = 3). Statistical analysis was performed using a two-sample t-test. ns, not significant; *p < 0.05; **p < 0.01; ***p < 0.001.
