Effect of VERU-111 on the expression of β-tubulin isotypes in PanCa cells. (A) Effect of VERU-111 on mRNA expression of βI, βIIa, βIIb, βIII, βIVa, βIVb, βV and βVI-tubulins in Panc-1 (i) and AsPC-1 (ii) cells. Briefly, cells were treated with the indicated concentrations of VERU-111 for 24 h. RNAs were isolated and transcribed for cDNA preparation. qPCR was performed to determine the mRNA expression of indicated tubulin isotypes. GAPDH was used as an internal control. Bar graphs represent relative fold expression of various tubulins mRNA. (Values mean ± SEM; n = 3). Asterisk (*) denotes the significant value p < 0.05. (B) Effect of VERU-111 on protein levels of various β-tubulin isotypes in Panc-1 (i) and AsPC-1(ii) cells. Cells were treated with vehicle or indicated concentrations of VERU-111 for 24 h and cell lysates were subjected for Western blot analysis. Equal loading of protein in each well was confirmed by stripping and re-probing of the blots with GAPD for all isoform were provided in Additional file 7: Figure S2
