Figure Lengend Snippet: Spironolactone selectively induces cell death and inhibits the growth of cancer cells. A549, PANC-1, PC-9, and PC-9-OR (osimertinib-resistant) ( a ), cancer stem cell lines (A549 CSLC and PANC-1 CSLC) ( b ), and IMR90 normal human fibroblasts ( c ) were treated without (as control) or with the indicated concentrations of spironolactone (SPL) for three days, and the numbers of viable and dead cells (left panels) as well as the percentage of dead cells (right panels) were then assessed. Values in the graphs represent the means ± SD of triplicate samples of a representative experiment repeated with similar results. * p < 0.05.

Figure Lengend Snippet: Spironolactone decreases survivin expression and survivin reductions imitate the chemosensitizing effects of spironolactone. Cells treated with or without 25 µM spironolactone (SPL) for three days were subjected to an immunoblot analysis for survivin expression ( a , b ). YM155, a pharmacological survivin inhibitor, at the concentration of 10 nM and the knockdown of survivin reduced survivin expression in cancer cells (A549) ( c ). The pharmacological or genetic inhibition of survivin sensitized cancer cells (A549) to chemotherapeutic reagents (GEM, gemcitabine, 0.1 µM; OSI, osimertinib, 2 µM) ( d ). * p < 0.05.

Figure Lengend Snippet: Spironolactone induces similar effects in GS-Y01, a glioma stem cell line, to those in cancer stem cells (CSCs) of Non-small cell lung cancer (NSCLC) and pancreatic cancer. GS-Y01 cells were treated without (as control) or with the indicated concentrations of spironolactone (SPL) for three days, and the numbers of viable and dead cells (left panel) as well as the percentage of dead cells (right panel) were then assessed ( a ). Cells treated with or without spironolactone (SPL) for three days were subjected to an immunoblot analysis for survivin expression ( b ). Glioma stem cells were treated with the indicated chemotherapeutic reagents (OSI, osimertinib) in the absence or presence of spironolactone (SPL) for three days, and the numbers of viable and dead cells (left panel) as well as the percentage of dead cells (right panel) were then assessed ( c ). Values in the graphs represent the means ± SD of triplicate samples of a representative experiment repeated with similar results. * p < 0.05.

Figure Lengend Snippet: Spironolactone sensitizes cancer cells to osimertinib in vivo. Mice (five for each group) were subcutaneously implanted with A549 cells. After the confirmation of tumor formation, mice were treated with or without osimertinib and/or spironolactone as detailed in the Materials and Methods. Tumor volume ( a ) and mouse body weight ( b ) were measured, and the results obtained are presented in the graphs as the means ± SD of each group. * p < 0.05, compared with control group in ( a ) and comparison between spironolactone treatment group and combination group in ( b ).
