The effect of CHIP on the mobilization of autologous CD34+ peripheral blood stem cells (PBSC) has not been reported. This study uses a DNA-based targeted candidate gene approach to identify the presence of somatic mutations in ASXL1, DNMT3A, JAK2, SF3B1, TET2 and TP53 in CD34+ haematopoietic progenitor cell-apheresis products of 96 patients who undergo PBSC mobilization for autologous stem cell transplantation (ASCT). Variants were identified in a significantly greater proportion of patients who experience poor CD34+ PBSC mobilization. A DNA-based targeted candidate gene array is able to predict poor CD34+ PBSC mobilization and may be deployed pre-emptively to minimize mobilization and graft failures.Mammalian phospholipase C (PLC) isozymes are major signaling nodes that regulate a wide range of cellular processes. Dysregulation of PLC activity has been associated with a growing list of human diseases such as cancer and Alzheimer's disease. However, methods to directly and continuously monitor PLC activity at membranes with high sensitivity and throughput are still lacking. We have developed XY-69, a fluorogenic PIP2 analog, which can be efficiently hydrolyzed by PLC isozymes either in solution or at membranes. Here, we describe the optimized assay conditions and protocol to measure the activity of PLC-γ1 (D1165H) with XY-69 in lipid vesicles. The described protocol also applies to other PLC isozymes.Phosphoinositides play important roles in the regulation of protein recruitment at specialized membrane domains, protein activity, and membrane dynamics. Phosphoinositide-protein interplay occurs via multiple mechanisms and proteins associate with membranes through different binding patterns. Determinations of membrane-binding mode and membrane penetration depth of proteins in lipid bilayer are thus important steps in
