The role of microRNAs in platelet biology during storage.
Platelet storage lesions seriously affect the quality of stored platelets, even causing them to be ineffective in vivo after transfusion. Past research have been focused on what mechanism(s) cause the formation of storage lesions. One proposed mechanism is microRNAs (miRNAs)-based molecular regulation of the platelet mRNAs that are relevant to the storage lesion. Platelets continue to translate proteins from mRNA while in a storage environment. A strong correlation exists between the platelet transcriptome and its subsequent proteomic profile, which supports de novo platelet translational capabilities. Thus, miRNA may play a crucial role in platelet biology during storage conditions. Importantly, this suggests the exciting possibility of post-transcriptional regulation of gene expression in platelets that are in storage. Given this, the differential profiling of miRNAs could be a useful tool in identifying changes to ex vivo stored platelets. Any identified miRNAs could then be considered as potential markers to assess the viability of platelet concentrates. The present review summarizes the current experimental and clinical evidence that clarifies the role miRNAs play during platelet ex vivo storage.
