Expression analyses of total GSK3α/β, p-GSK3α/β (Tyr279/216) and p-GSK3α/β (Ser21/9) in permanent HNSCC cell lines UT-SCC-16A/B and UT-SCC-60A/B showed no correlation between the different expression levels (Figure 4A). This evidence concerns the gene GSK3A and head and neck squamous cell carcinoma.
