Figure 5From: Deoxycholate promotes survival of breast cancer cells by reducing the level of pro-apoptotic ceramideDC promotes expression of Flk-1, which is prevented by Z-guggulsterone. (a) RT-PCR for the expression of Flk-1 in 4T1 cells. (b) Immunoblot for the expression of Flk-1. (c) Flow cytometry for the expression of CD44 and Flk-1 in 4T1 cells cultivated in serum-free medium with or without DC. Note that CD44 and Flk-1 were co-expressed. DC, sodium deoxycholate; Gug, guggulsterone (50 μmol/l).Back to article page
