Abstract

Melanoma is one of the most deadly skin cancers. T‑cadherin is an atypical member of the cadherin superfamily as it lacks the transmembrane and cytoplasmic domains and is anchored to cell membranes through glycosylphosphatidylinositol (GPI) anchors. T‑cadherin downregulation is associated with a poorer prognosis in various carcinomas, such as lung, ovarian, cervical and prostate cancer, while in the majority of cancer cell lines, T‑cadherin re‑expression inhibits cell proliferation and invasiveness, increases susceptibility in apoptosis and reduces tumor growth in in vivo models. The functional relevance of T‑cadherin gene expression in melanoma progression remains to be clarified. The present study was designed for this purpose. The T‑cadherin gene was transfected into B16F10 melanoma cells to express T‑cadherin in the cells which were originally deficient in T‑cadherin expression. The proliferation, invasiveness, apoptosis and cell cycle of the transfected B16F10 melanoma cells were analyzed. The present study showed that the expression of T‑cadherin in B16F10 melanoma cells markedly reduced cell proliferation and permeation through Matrigel‑coated membranes, representing invasiveness. The percentage of early apoptotic cells and cells in the G2/M phase of the cell cycle was markedly increased compared with either parental B16F10 (without transfection) or empty pEGFP‑N1 (without T‑cadherin gene)‑transfected B16F10 cells, suggesting G2/M arrest, with similarity between the parental and empty pEGFP‑N1‑transfected B16F10 cells. T‑cadherin is important in melanoma progression and may be a possible target for therapy in melanoma and certain other types of cancer.
