A. Comparison of fold changes of P2RX3 expression in undifferentiated H1 hESCs and hESC-derived NPCs treated with EtOH. P2RX3 in undifferentiated hESCs was downregulated and conversely upregulated in NPCs with increased EtOH concentration. Bars are mean ± SEM from triplicates; significant (p<0.05) difference from control (one-way ANOVA). B. The level of CNTNAP4 and P2RX3 in H1 NPC was induced by treatment with 20 mM EtOH. Co-treatment with 1 μM dihydromyricetin (DHM), a flavonoid component of herbal medicines that counters acute EtOH intoxication, significantly interfered the effect of EtOH, demonstrating the specificity of EtOH’s effect on the gene expression. Bars are mean ± SEM from triplicates; significant (p<0.05) difference from control (one-way ANOVA). C. Relative protein levels of P2RX3 in undifferentiatied H9 hESCs and H9 NPC cell lines treated with 0, 20, and 50 mM EtOH for 48 hrs. From Western analysis, we have confirmed alcohol-induced downregulation of P2RX3 in undifferentiated hESCs and upregulation in NPCs.
