Here, we show that the prostate cancer stem cell (pCSC)-like traits, such as accelerated activity of aldehyde dehydrogenase 1 (ALDH1), enrichment of CD49f+ fraction, and sphere forming efficiency, are attenuated by SFN treatment.
To further analyze the consequences of hypoxic upregulation on stem cell proliferation and HIF1α signaling, CSC subpopulations from murine TRAMP-C1 cells (Sca-1(+)/CD49f(+)) as well as from a human prostate cancer cell line (CD44(+)/CD49f(+)) were isolated and characterized.
