CD95 promotes tumour growth

Fas (CD95) expression in myeloid cells promotes

Vascular endothelial growth factor-C-mediated lymphangiogenesis promotes tumour metastasis.

Metastasis is a frequent and lethal complication of cancer. Vascular endothelial growth factor-C (VEGF-C) is a recently described lymphangiogenic factor. Increased expression of VEGF-C in primary tumours correlates with dissemination of tumour cells to regional lymph nodes. However, a direct role for VEGF-C in tumour lymphangiogenesis and subsequent metastasis has yet to be demonstrated. Here w...

Chronic Restraint Stress Promotes Lymphocyte Apoptosis by Modulating Cd95 Expression

Depending on the duration and severity, psychological tension and physical stress can enhance or suppress the immune system in both humans and animals. Although it is well established that stress alters the release of various hormones and neurotransmitters, the mechanisms by which stress affects immune responses remain elusive. We report here that mice subjected to chronic 12-hour daily physica...

Carbon monoxide promotes Fas/CD95-induced apoptosis in Jurkat cells.

A properly functioning immune system is dependent on programmed cell death/apoptosis at virtually every stage of lymphocyte development and activity. Carbon monoxide (CO), an enzymatic product of heme oxyenase-1, has been shown to possess anti-apoptotic effects in a number of different model systems. The purpose of the present study was to expand on this knowledge to determine the role of CO in...

The death receptor CD95 activates the cofilin pathway to stimulate tumour cell invasion.

The death receptor CD95 promotes apoptosis through well-defined signalling pathways. In colorectal cancer cells, CD95 primarily stimulates migration and invasion through pathways that are incompletely understood. Here, we identify a new CD95-activated tyrosine kinase pathway that is essential for CD95-stimulated tumour cell invasion. We show that CD95 promotes Tyr 783 phosphorylation of phospho...
