Ran GTPase is an independent prognostic marker in malignant melanoma which promotes tumour cell migration and invasion.

Aims: Ran GTPase is involved in nucleocytoplasmic shuttling of proteins and is overexpressed in several cancers. The expression of Ran in malignant melanoma (MM) and its functional activity have not been described and were investigated in this study.

Methods: The prognostic value of Ran expression was tested in a series of 185 primary cutaneous MM cases using immunohistochemistry.

Cten promotes Epithelial-Mesenchymal Transition (EMT) in colorectal cancer through stabilisation of Src.

Cten is an oncogene promoting EMT in many signaling pathways, namely through Snail. We investigated whether Cten function could be mediated through Src. Cten levels were modulated by forced expression in HCT116 and gene knockdown in SW620 CRC (colorectal cancer) cell lines.

TGFβ1-induced cell motility but not cell proliferation is mediated through Cten in colorectal cancer.

Cten (C-terminal tensin-like) is a member of the tensin protein family found in complex with integrins at focal adhesions. It promotes epithelial-mesenchymal transition (EMT) and cell motility. The precise mechanisms regulating Cten are unknown, although we and others have shown that Cten could be under the regulation of several cytokines and growth factors.
