Mass spectrometry-based analysis on the impact of iron status and whole blood donation on the global plasma proteome

Description

Blood donation is generally considered to be safe, however to ensure blood donor health it is important to monitor the impact of a whole blood donation. Study design and methods Here, we used quantitative mass spectrometry to assess the global plasma proteomic impact of longitudinal whole blood donation in 5 new and 4 regular donors over a period of 180 days as well as the effect on iron status, by selecting 78 donors based on high levels of ferritin and hemoglobin. The majority of plasma proteins were stable between whole blood donors and demonstrated a low coefficient of variation, irrespective to iron status or donors status (new or regular). Longitudinal analysis showed limited differences between the plasma proteomes of regular and new upon a whole blood donation, apart from a consistent and significant short-term decrease in fibronectin. Plasma protein levels measured with MS highly correlated with blood count and lipid parameters, validating our MS-approach. Based on protein co-expression, we observed protein complexes of diverse biological processes, platelet and neutrophil signatures, complement and immune responses with a highly correlating cluster of IGHM, IGJ and CD5L. We showed higher inter- than intra-individual variation, most notably of immunoglobulins and allelic variants for alpha-1 antitrypsin. Overall, this study shows that whole blood donation has limited impact for both new and regular donors apart from short-term decreases in fibronectin and that varying iron statuses do not affect the global plasma proteome. We showed that individual specific signatures were reflected on the plasma proteome as well as detection of allelic variants [dataset license: CC0 1.0 Universal (CC0 1.0)]

Click here to queue conversion of this dataset's submitted spectrum files to open formats (e.g. mzML). This process may take some time.

When complete, the converted files will be available in the "ccms_peak" subdirectory of the dataset's FTP space (accessible via the "FTP Download" link to the right).
Number of distinct conditions across all analyses (original submission and reanalyses) associated with this dataset.

Distinct condition labels are counted across all files submitted in the "Metadata" category having a "Condition" column in this dataset.

"N/A" means no results of this type were submitted.
Number of distinct biological replicates across all analyses (original submission and reanalyses) associated with this dataset.

Distinct replicate labels are counted across all files submitted in the "Metadata" category having a "BioReplicate" or "Replicate" column in this dataset.

"N/A" means no results of this type were submitted.
Number of distinct technical replicates across all analyses (original submission and reanalyses) associated with this dataset.

The technical replicate count is defined as the maximum number of times any one distinct combination of condition and biological replicate was analyzed across all files submitted in the "Metadata" category. In the case of fractionated experiments, only the first fraction is considered.

"N/A" means no results of this type were submitted.
Originally identified proteins that were automatically remapped by MassIVE to proteins in the SwissProt human reference database.

"N/A" means no results of this type were submitted.
Number of distinct protein accessions reported across all analyses (original submission and reanalyses) associated with this dataset.

"N/A" means no results of this type were submitted.
Number of distinct unmodified peptide sequences reported across all analyses (original submission and reanalyses) associated with this dataset.

"N/A" means no results of this type were submitted.
Number of distinct peptide sequences (including modified variants or peptidoforms) reported across all analyses (original submission and reanalyses) associated with this dataset.

"N/A" means no results of this type were submitted.
Total number of peptide-spectrum matches (i.e. spectrum identifications) reported across all analyses (original submission and reanalyses) associated with this dataset.

"N/A" means no results of this type were submitted.
Number of distinct proteins quantified across all analyses (original submission and reanalyses) associated with this dataset.

Distinct protein accessions are counted across all files submitted in the "Statistical Analysis of Quantified Analytes" category having a "Protein" column in this dataset.

"N/A" means no results of this type were submitted.
Number of distinct proteins found to be differentially abundant in at least one comparison across all analyses (original submission and reanalyses) associated with this dataset.

A protein is differentially abundant if its change in abundance across conditions is found to be statistically significant with an adjusted p-value <= 0.05 and lists no issues associated with statistical tests for differential abundance.

Distinct protein accessions are counted across all files submitted in the "Statistical Analysis of Quantified Analytes" category having a "Protein" column in this dataset.

"N/A" means no results of this type were submitted.
This dataset may not contain all raw spectra data as originally deposited in PRIDE. It has been imported to MassIVE for reanalysis purposes, so its spectra data here may consist solely of processed peak lists suitable for reanalysis with most software.
