Apoptosis
Study findings on apoptosis are outlined in reports from University of Heidelberg
September 2nd, 2008
According to a study from Mannheim, Germany, "Marked reduction in apoptosis is a hallmark of early colon tumour growth and the vast majority of these tumours exhibit a loss of expression of the glycoprotein carcinoembryonic-antigen-related cell adhesion molecule 1 (CEACAM1). We recently reported that the CEACAM1 functions as a mediator of apoptosis implicating this cell surface protein in early tumour development." "However, the mechanistic involvement of CEACAM1 in cell death pathways is unclear. Here, we show that apoptosis triggers cleavage of the long form of CEACAM1 (CEACAM1-4L) at intracellular and extracellular sites in Jurkat cells and HEK293 cells. Signalling...
