From: The dietary bioflavonoid quercetin synergizes with epigallocathechin gallate (EGCG) to inhibit prostate cancer stem cell characteristics, invasion, migration and epithelial-mesenchymal transition

Inhibition of Nanog enhances the effects of EGCG on CSC spheroid formation. CD133+ and CD44+ CSCs were isolated from PC-3 cells and plated in six-well ultralow attached plates at a density of 1,000 cells/ml. (A), CSCs were transduced with either scrambled shRNA or Nanog shRNA expressing lentiviral vector (pLKO.1), and cell lysates were collected and western blot analysis was performed using anti-Nanog antibody. (B), CSC/scrambled and CSC/Nanog shRNA were seeded as described above and treated with EGCG (0-80 μM). After 7 days, spheroids were collected and cell suspentions were prepared and viable cells were counted by trypan blue assay. Data represent mean ± SD. * or ** = significantly different from control, P < 0.05.
