Figure Lengend Snippet: Western blot analysis and densitometry measurements of treated TNBC cell lines with arachidin-1 (A-1, 0.1, and 1 µM). Western blot images of ( A ) PARP and cleaved PARP, GAPDH loading control. ( B ) Full-length caspase-8, GAPDH loading control; ( C ) cleaved caspase-9, vinculin loading control; and ( D ) survivin, GAPDH loading control. Lysates (60 µg of total protein) of MDA-MB-231 and MDA-MB-436 cells treated with A-1 were analyzed by western blotting. The relative densitometry of ( E ) full-length PARP, ( F ) cleaved PARP, ( G ) caspase-8, ( H ) cleaved caspase-9, and ( I ) survivin protein levels were analyzed by comparing to the loading control. Cells with 0.01% DMSO were used as controls. Data represents mean ± SD from three or more independent experiments. * p < 0.05, ** p < 0.001, **** p < 0.0001 versus control in MDA-MB-231, # p < 0.05, ## p < 0.001, #### p < 0.00001 versus control in MDA-MB-436, and ns = not significant from control.
