FIGURE 4.

Bar graphs showing % AzMC fluorescence. Graph A compares Paclitaxel (10 nM) with and without HMPSNE; graph B compares Capecitabine (10 μM) with and without HMPSNE; graph C compares Doxorubicin (1 μM) with and without HMPSNE. Statistical significance is indicated by asterisks.

Effects of HMPSNE (100 µM), either alone or in combination with various chemotherapeutic drugs, such as (A) paclitaxel, (B) capecitabine, (C) doxorubicin, on H2S levels in MDA-MB-231 cells. The data are presented as the means ± SEMs of three independent experiments; *P < 0.05 and **P < 0.01 indicate significant differences between the indicated groups.
