The expression of GSK3α and GSK3β
proteins in the tumor/ normal tissues of various anatomical sites of the mouth. (A) Representative immunostaining showing the differential expression of GSK3α and GSK3β from consecutive sections in various types of oral tumor tissue samples as indicated in the figure. (a, b) SCC (cheek); (c, d) Mucoepidermoid carcinoma (palate); (e, f) Adamantinoma (mandible); (g, h) SCC (gingiva); (i, j) SCC (lower mandible); (k, l) Adenoid cystic carcinoma (palate); (m, n) Basal cell carcinoma (lip); (o, p) Acinic cell carcinoma (parotid gland); (q, r) Mucoepidermoid carcinoma (root of the tongue). (s, t) Normal salivary gland, (u, v) Mucoepidermoid carcinoma (parotid gland) (w, x) and SCC (lip) showed differential expression of GSK3α and GSK3β. The maximum intense immunoreactivity of GSK3β was observed in SCC compared to other types of oral tumors. Original magnification 100X. (B) Overexpression of GSK3β is significantly higher in SCC than in the other types of (non-SCC) oral cancers (p < 0.0001).
