Core Tip

Core tip: Aberrant co-expression of phosphorylated form of glycogen synthase kinase-3β (pS9GSK-3β) and β–catenin proteins and their association with tumor stage, tumor type, smoking/tobacco chewing status and shorter overall survival probabilities of urinary bladder cancer patients validate them as potential markers of diagnostic/prognostic significance in disease pathogenesis. Observed histopathological association of nuclear Cyclin D1 identifies it as a marker of potential relevance in tumors with altered pS9GSK-3β/β-catenin proteins. These results rule out the possible post translational activation of target genes examined, by pS9GSK-3β/β-catenin/T-cell factor/lymphoid enhancer factor transcriptional complex in bladder tumorigenesis.
