Project description:To investigate the microRNAs (miRNAs) expression profiles in human apheresis platelet under platelet storage lesion (PSL), and predict the potential biomarkers in the process of PSL. miRNAs profiles of platelets were tested by illumina HiSeq2500 between PSL and nonPSL. 13 miRNAs were chosen to validate by real-time PCR, the result was consistent with the sequencing results.
Project description:To investigate the long noncoding RNA (lncRNA) expression profiles in human apheresis platelet during the storage, and predict the potential biological function of lncRNAs in the process of platelet storage lesion. LncRNAs profiles of platelets were tested by Agilent Human lncRNA Array at 2nd, 5th, and 8th day during storage. Seven lncRNAs and four mRNAs were chosen to validate by real-time PCR, the result was consistent with the microarray. Bioinformatics method was applied to predict the function of lncRNAs.
Project description:Circulating platelets from Sickle cell disease (SCD) patients express distinct gene expression patterns that regulate function. The objective of this study is to identify a role of post-transcriptional regulation of the platelet transcriptional signaling by microRNAs. Comparison of microRNA expression in platelets from SCD patients and control subjects, from 2 cohorts-University of Pittsburgh and National Institutes of Health.

Project description:To compare immature and mature platelet transcriptome Methods: reticulated or immature platelets(RPs) were defined as the platelets with the highest thiazole orange staining intensity (15% highest, RNAhigh) according to previous experiences and mature platelets were defined as the platelet with the 30% lowest thiazole orange staining intensity (RNAlow) and sorted (supplemental Figure S1D). RPs have a prothrombotic transcriptomic profile
Project description:Investigation of miRNA expression level changes of human platelets stored for 2, 5 and 8 days,and to explore the mechanism of storage lesions of human platelets.
Project description:To compare immature and mature platelet transcriptome Methods: reticulated or immature platelets(RPs) were defined as the platelets with the highest thiazole orange staining intensity (15% highest, RNAhigh) according to previous experiences and mature platelets were defined as the platelet with the 30% lowest thiazole orange staining intensity (RNAlow) and sorted (supplemental Figure S1D). We detected more than 1700 differentially expressed gene, incluning activation receptors RPs have a prothrombotic transcriptomic profile
Project description:Human platelets collected from healthy donors according to standard international protocols were pooled and stored at 4ºC during 7 days. The small RNA population changes across the days were evaluated by NGS aproach. The smallRNA population was evaluated at fresh platelets and after 1 day, 2 days, 3 days, 4 days, 5 days and 7 days of storage at 4ºC.
