Project description:This study investigates the proteomic alterations in bone marrow neutrophils isolated from 5-8 week old Gfi1+/-, Gfi1K403R/-, Gfi1R412X/-, and Gfi1R412X/R412X mice using the SWATH-MS technique. This dataset consists of 26 raw MS files, comprising 13 DDA (for spectral library generation)and 13 DIA (for SWATH) runs on a TripleTOF 5600 plus (SCIEX). Our findings revealed significant changes in the expression of neutrophil granule proteins and NADPH-oxidase complex components in Gfi1-mutant neutrophils.
Project description:Local renin antiotensin systems have been identified for many extra-renal sites. Bone marrow has been proposed as one such site, although the nature of the renin-expressing cell type(s) has not been established. Affymetrix microarrays were used to characterize the expression profile of renin-expressing GFP positive cells. Green fluorescent protein positive cells were sorted from whole bone marrow collected from adult transgenic mice. Bone marrow from several mice was collected and pooled on the day of a FACS sort. A portion of this was reserved for RNA extraction while the remainder was sorted. RNA was prepared with Trizol. Bone marrow collection and sorting was performed 3 times so that microarrays could be run in triplicate.
