Carcinoma
New carcinoma study findings have been published by J. Meijer and colleagues
December 18th, 2008
According to recent research from Netherlands, "The chemokine CXCL12/SDF-1 and its receptor CXCR4 have been implicated in invasion, survival and proliferation of carcinoma cells. Recently, CXCR7 was identified as a second receptor for CXCL12." "We observed that CXCL12 promoted proliferation of CT26 colon and KEP1 mammary carcinoma cells, and this was blocked when CXCR7 was downregulated by 'intrakines' or RNAi, but not by CXCR4 inhibitors. The K1R mutant of CXCL12, which acts as a CXCR4 antagonist, also promoted proliferation through CXCR7 and is therefore a selective CXCR7 agonist. The effect of CXCR7 was not due to reduced apoptosis, and CXCR7 mediated chemotaxis of...
