These data suggest that aspirin exposure may alter the genomic and proteomic content of circulating platelets.
There is a direct correlation between the LDL content of circulating immune complexes and serum atherogenic potential [ 4].
Therefore, it is vital to continuously monitor the genetic content of circulating influenza strains and keep an eye out for new reassortants.
Tumor-derived nucleic acids can be detected as cell-free entities, attached to lipid or protein structures, or as content of circulating EVs or blood platelets [ 38, 40, 43, 116, 150, 155].
For this reason they hypothesized that the genomic response to a pharmacological 'challenge' with aspirin could be due to aspirin exposure that altered the genomic and protein content of circulating platelets.
Combining the findings in our previous study with the current results, we can assume that the poor effect of human serum obtained on the first 3 days after fracture for in vitro proliferation and differentiation of MSCs can be attributed to the low content of circulating growth factors.
From this point of view, our study finds a clinical implication and although we did not analyze the effect of aspirin on ARS gene expression or GpIIIa platelet expression, our data support both hypotheses and we can affirm that aspirin is able to alter the protein content of circulating platelets.
To quantify the content of circulating endothelial progenitors (CEPs) in lapatinib-treated A549 xenografts by flow cytometry analysis, a volume of 100-200 μL peripheral blood was pre-incubated for 30 min at 4°C with 200 μL PBS-EDTA-BSA (phosphate 10 mM, 3% EDTA, 2% bovine serum albumin pH 7.4).
Studies on the contents and role of circulating (apoptotic) MVs in lupus mice and patients are scarce and largely limited to in vitro-generated apoptotic MVs, which indeed contain lupus autoantigens, such as chromatin, and are recognized by lupus-derived autoantibodies [ 20- 23].
