Description

This dataset consists of semi-quantitative 10-plex TMT proteomics analysis of FACS-separated bone marrow cells obtained from 3 healthy bone marrow donors and 3 MDS-RS patients. The objective of this data collection was to assess several parameters on how the bone marrow of MDS-RS patients differs from that of healthy donors. The samples included in this analyses were 3 samples of sorted GPA+ erythroblasts pooled from 5 healthy donors (2+2+1) and 3 samples of sorted GPA+ erythroblasts plus 3 samples of purified ring sideroblats from 3 MDS-RS patients.

This dataset includes the raw mass spectra, QC and processed results.

Processing: In short, FACS-separated samples were snap frozen in liquid nitrogen. Cell pellets were lysed with 4 % SDS lysis buffer and prepared for mass spectrometry using a modified version of the SP3 protein clean up and digestion protocol published by Moggridge S. et al 2018.

Mixed probability and non-probability

Bone marrow (BM) and/or peripheral blood (PB) samples were collected from 36 MDS-RS and 3 MDS non-RS patients evaluated at Karolinska University Hospital, Huddinge, Sweden. Diagnostic procedures were performed according to the European LeukemiaNet recommendation and WHO classification for myeloid neoplasms. As the specific purpose was to dissect the pathobiology of SF3B1-mutant MDS-RS, all MDS-RS patients belonged to the SF3B1α category in the IPSS-M risk classification. RS presence was quantified according to standard clinical practice. Additional samples were collected from a total of 40 healthy normal bone marrow (NBM) donors for control purposes. Please note that a deidentified donor and experiment index is provided in the companion publication for this dataset, including clinical and mutational status. All source material was provided with written informed consent for research use, given in accordance with the Declaration of Helsinki.

In this dataset, samples from 3 MDS-RS patients and 3 healthy donors are included.
