PinX1 is down-regulated and EMT process is promoted in nasopharyngeal CD133⁺ CSCs. a The mRNA expressions of PinX1, E-cadherin, Vimentin, Snail1, Twist1, and Zeb1 in nasopharyngeal CD133⁺ CSCs and CD133⁻ cells as determined by RT-qPCR. b The protein levels of PinX1, E-cadherin, Vimentin, Snail1, Twist1, and Zeb1 in nasopharyngeal CD133⁺ CSCs and CD133⁻ cells as measured by western blot analysis. The grey value of the protein was normalized to that of the corresponding GAPDH. ** p < 0.01 vs. nasopharyngeal CD133⁻ CSCs, *** p < 0.001 vs. nasopharyngeal CD133⁻ CSCs
