Proteomic analysis of leukocytes upon Plekhm1-KO


ABSTRACT: Leukemia cells instruct their surrounding bone marrow microenvironment (BMM) rendering it hospitable to leukemia cell survival. Conversely, how cells of the BMM influence leukemia progression is less well understood. Pleckstrin homology domain family M member 1 (PLEKHM1) serves as a hub between fusion and secretion of intracellular vesicles. Here, we performed TMT-based quantitative proteomics to investigate the proteome of BMM-derived leucocytesfrom mice lacking Plekhm1 compared to wild-type animals, which have been transplanted withBCR-ABL1-expressing bone marrow cells.

Leukemia cells reciprocally interact with their surrounding bone marrow microenvironment (BMM), rendering it hospitable to leukemia cell survival, for instance through the release of small extracellular vesicles (sEVs). In contrast, we show here that BMM deficiency of pleckstrin homology domain family M member 1 (PLEKHM1), which serves as a hub between fusion and secretion of intracellular vesicles and is important for vesicular secretion in osteoclasts, accelerates murine BCR-ABL1+ B-cell acute  ...[more]
