Transglutaminase 2 Stimulates Cell Proliferation and Modulates Transforming Growth Factor-Beta Signaling Pathway Independently of Epithelial-Mesenchymal Transition in Hepatocellular Carcinoma Cells.

ABSTRACT: Transglutaminase 2 (TG2) is a multifunctional protein and plays a role in cancer progression. We previously identified TG2 as an early-recurrence biomarker in hepatocellular carcinoma (HCC). TG2-knockdown (shTG2) and control (shCtl) HCC cell lines were used for comparative analyses to clarify the molecular mechanisms underlying the contribution of this protein to HCC malignancy. The proliferation of shTG2 cells was slightly but significantly decreased compared with that of shCtl cells. Differential gene expression profiling based on GeneChip arrays revealed the enrichment of the PI3K-Akt signaling pathway and showed that the expression of Dickkopf-1 and -3 (DKK1 and DKK3, respectively), inhibitors and modulators of the Wnt/β-catenin signaling pathway, was increased in shTG2 cells.
