The engulfment of dying cells is a specialized form of phagocytosis that is extremely conserved across evolution. In the worm, it is genetically controlled by two parallel pathways, which are only partially reconstituted in mammals. We focused on the recapitulation of the CED-1 defined pathway in mammalian systems. We first explored and validated MEGF10, a(More)
Multicellular animals rapidly clear dying cells from their bodies. Many of the pathways that mediate this cell removal are conserved through evolution. Here, we identify srgp-1 as a negative regulator of cell clearance in both Caenorhabditis elegans and mammalian cells. Loss of srgp-1 function results in improved engulfment of apoptotic cells, whereas(More)
The low density lipoprotein receptor-related protein (LRP-1) binds and mediates the endocytosis of multiple ligands, transports the urokinase-type plasminogen activator receptor (uPAR) and other membrane proteins into endosomes, and binds intracellular adaptor proteins involved in cell signaling. In this paper, we show that in murine embryonic fibroblasts(More)
Engulfment of apoptotic cells by phagocytes is important throughout development and adult life. When phagocytes engulf apoptotic cells, they increase their cellular contents including cholesterol and phospholipids, but how the phagocytes respond to this increased load is poorly understood. Here, we identify one type of a phagocyte response, wherein the(More)
The GTPase Arf6 regulates multiple cellular processes, including endocytosis, secretion, phagocytosis, cell adhesion, and cell migration [1, 2]. The Arf6-specific GAP ACAP1 is a negative regulator of Arf6-mediated signaling [3-7]. However, regulation of ACAP1- and Arf6-mediated signaling by other cellular proteins is not well understood. GULP/CED-6 is a(More)
A novel nanowire-structured polypyrrole-cobalt composite, PPy-CTAB-Co, is successfully synthesized with a surfactant of cetyltrimethylammounium bromide (CTAB). As an electro-catalyst towards oxygen reduction reaction (ORR) in alkaline media, this PPy-CTAB-Co demonstrates a superior ORR performance when compared to that of granular PPy-Co catalyst and also a(More)
Objective: Rs1495741 has been identified to infer N-acetyltransferase 2 (NAT2) acetylator phenotype, and to decrease the risk of bladder cancer. However, a number of studies conducted in various regions showed controversial results. To quantify the association between rs1495741 and the risk of bladder cancer, and to estimate the interaction effect of this(More)
