Protein expression of KRT13 is decreased in WSN patient cells.

(A) Observation of oral mucosal epithelial cell morphology from normal and WSN patient.

(B) The growth curve of WSN patient cell line and normal control cell line (P < 0.05). (C) Quantification of KRT mRNA (P < 0.05). All images shown are representative and data are mean ± s.e.m. of n ≥ 3 independent experimental groups. Results are representative of three independent experiments. All experiments were performed at least three times with similar results. (D) Analysis of the protein expression between normal and WSN. (E) Analysis of the protein expression in oral mucosal epithelial cells with/without MG132 treatment.
