Substitution of valine (Val) for aspartic acid (Asp) at codon 814 constitutively activates murine c-kit receptor tyrosine kinase (KIT), and Asp816Val mutation, corresponding to murine Asp814Val mutation, is found in patients with mastocytosis and acute myelocytic leukemia. However, the signal transduction pathways responsible for oncogenesis by the Asp814Val mutant (KIT(Val814)) are not fully u...
BACKGROUND In large-scale epidemiology, bloodspot sampling by fingerstick onto filter paper has many advantages, including ease and low costs of collection, processing and transport. We describe the development of an enzyme-linked immunoassay (ELISA) for quantifying insulin from dried blood spots and demonstrate its application in a large trial. METHODS We adapted an existing commercial kit (...
Most mouse thymocytes undergoing positive selection are found on one of two pathways; the c-Kit+ and the c-Kit- pathways. Here, we show that c-Kit and interleukin-7 receptor (IL-7R)-mediated signals support positive selection during the transition from the subpopulation that first expresses cell surface T cell receptor (TCR)-the TCRalpha/betaloCD4(int)/CD8(int) (DPint) c-Kit+ cells to TCRalpha/...
KIT is a cell surface tyrosine kinase receptor whose ligand stem cell factor (SCF) triggers homodimerization and activation of downstream effector pathways involved in cell survival, proliferation, homing, or differentiation. KIT-activating mutations are major oncogenic drivers in subsets of acute myeloid leukemia (AML), in mast cell leukemia, and in gastrointestinal stromal tumors (GIST). The ...
Use of dried blood spots for the determination of plasma concentrations of nevirapine and efavirenz.
OBJECTIVES Plasma concentrations are frequently used for therapeutic drug monitoring of antiretroviral drugs. Dried blood spot sampling offers a patient-friendly and easy alternative to plasma sampling. However, dried blood spot concentrations are not necessarily equal to plasma concentrations and therefore the objective of this work was to establish the relationship between nevirapine and efav...
