Research Finds New Link Between Inflammation and Cancer

 

Virginia Commonwealth University Massey Cancer Center researchers have uncovered a new link between chronic inflammation and cancer. Although cancers do not always cause inflammation, chronic inflammation is known to help tumor cells grow. In an article published in the June issue of Nature, VCU Massey scientists Sarah Spiegel, Ph.D., and Tomasz Kordula, Ph.D., and their co-authors examine how sphingosine-1-phosphate (S1P), a lipid mediator in the blood that influences immune cell circulation, also regulates inflammation and cancer. They reported that S1P is a missing cofactor that is required for the activity of TRAF2, the key regulator of NF-kappaB, which acts as a master on-off switch in controlling inflammation and cancer.
