beta-D-galactose-containing glycoproteins were prepared from cells P-388 leukemia and from P-388 leukemia cells with induced resistance to doxorubicin. It was shown by HPLC method that plasma membranes from resistant cells contain 4-4.5% P-glycoproteins and plasma membranes from sensitive cells
BACKGROUND
Various cytomorphologic and biochemical markers of apoptosis are found in different compartments (plasma membrane, cytoplasm, nucleus, and mitochondria) of target cells. Although the plasma membrane is an easily accessible cellular compartment, relatively little is known about its changes
Recently, we found increased levels of alpha-d-mannose- and beta-d-galactose-containing glycoproteins in plasma membrane of the apoptotic murine leukemia L1210 cells (Bilyy & Stoika 2003). That indicator was suggested to be a novel marker of apoptosis in L1210 cells. The aim of our present work was
Post-polymerization modification of a poly(pentafluorostyryl) backbone with β-d-galactose and a terpyridine platinum complex yields a well-defined material that represents the first example of a metal-conjugated glycopolymer. It reveals anti-proliferative activity, no detectable necrotic
We recently established that an increased expression of alpha-D-mannose (Man)- and beta-D-galactose-rich plasma membrane glycoproteins (GPs) is characteristic for apoptotic cells in vitro [Bilyy, R.O., Stoika, R.S., 2003. Lectinocytochemical detection of apoptotic murine leukemia L1210 cells.
