The effects of visfatin on MUC16, MUC8, MUC5B, MUC5AC, and MUC4 expression in NCI-H292 cells. RT-PCR showed that visfatin induced remarkable MUC8 and MUC5B mRNA expression. However, visfatin did not definitely induce MUC16, MUC5AC, and MUC4 mRNA expression. Images are representative of three separate experiments performed in triplicate. Bars indicate the mean ± S.D. of three independent experiments performed in triplicate. * P < 0.05 compared with zero value.
