The accumulation of exosome-associated microRNA-1246 and microRNA-150-3p in human red blood cell suspensions
BACKGROUND: Transfusion-related immunomodulation (TRIM) can be caused by exosomes, in which case, microRNAs (miRNAs) are one critical factor impacting exosome behavior. This study aims to investigate and analyze the expression profiles of exosomal miRNA in red blood cell (RBC) suspensions during storage and to identify potential TRIM-related miRNAs as well as their potential functions.
METHODS: A total of 25 packs of RBC suspensions were randomly collected. Exosome were extracted by ultracentrifugation and then identified and characterized by nanoparticle tracking analysis (NTA), transmission electron microscopy (TEM) and western blot (WB). Exosomal miRNA profiles were acquired using gene chips in five packs on week 1 and week 5. The expression data were compared from the two time points identifying accumulated miRNAs with statistical significance and their predicted targeting genes were analyzed. Based on the gene chip results, quantitative reverse transcription-polymerase chain reactions (qRT-PCR) were performed to verify miRNA accumulation in the rest 20 packs sampling on week 1, 3 and 5.
RESULTS: Gene chip analysis revealed that most exosomal miRNAs were enriched as the storage period progressed. Compared to samples from week 1, week 5 samples exhibited a total of 539 differential miRNA expressions, among which, 159 were statistically significant (P < 0.05) and 148 (93.08%) were accumulated. In the bioinformatics functional analysis, significant immunoregulatory annotations related to the thyroid hormone, mitogen-activated protein kinase (MAPK), focal adhesion and RAS signaling pathways were identified. The top 17 differential expression miRNAs were validated by qRT-PCR. The results confirmed that all the 17 miRNAs were accumulated with increasing storage time. In particular, miRNA-1246 and miRNA-150-3p were the most enriched strands by more than 150-folds in the 5-week storage period.
CONCLUSIONS: As storage progressed, numerous exosomal miRNAs accumulated in the RBC suspensions, which are informatically connected to multiple immuno-signaling pathways. MiRNA-1246 and miRNA-150-3p may be essential mediators impacting the immunoregulation functions of exosomes in RBC suspensions, considering their significant accumulating scales. Further research should therefore focus on the relationship between these miRNAs and TRIM.
