Figure 8From: Epigallocathechin gallate, polyphenol present in green tea, inhibits stem-like characteristics and epithelial-mesenchymal transition in nasopharyngeal cancer cell lines Expression of stemness genes was blocked by EGCG. The expression of stem cell genes (Oct4, Sox2, Klf4) of TW01 sphere-derived cells treated with EGCG was measured by the q-RT-PCR. Decreasing expression of OCT4 and Klf4 was accompanied with EGCG dosage. Data is represented mean ± SD. * or # means significantly different from respective controls, p < 0.05.Back to article page
