Abstract
Stem cell therapy provides a hope to no option heart disease patient group. Stem cells work via different mechanisms of which paracrine mechanism is reported to justify most of the effects. Therefore, identifying the control arms for paracrine cocktail production is necessary to tailor stem cell functions in disease contextual manner. In this study, we describe a novel paracrine cocktail regulatory axis, in stem cells, to enhance their cardioprotective abilities. We identified that HSF1 knockout resulted in reduced cardiac regenerative abilities of mesenchymal stem cells (MSCs) while its overexpression had opposite effects. Altered exosome biognesis and their miRNA cargo enrichment were found to be underlying these altered regenerative abilities. Decreased production of exosomes by MSCs accompanied their loss of HSF1 and vice versa. Moreover, the exosomes derived from HSF1 depleted MSCs showed significantly reduced candidate miRNA expression (miR-145, miR-146, 199-3p, 199b and miR-590) compared to those obtained from HSF1 overexpressing MSCs. We further discovered that HSF1 mediates miRNAs' enrichment into exosomes via Y binding protein 1 (YBX1) and showed, by loss and gain of function strategies, that miRNAs' enrichment in mesenchymal stem cell derived exosomes is deregulated with altered YBX1 expression. It was finally demonstrated that absence of YBX1 in MSCs, with normal HSF1 expression, resulted in significant accumulation of candidate miRNAs into the cells. Together, our data shows that HSF1 plays a critical role in determining the regenerative potential of stem cells. HSF1 does that by affecting exosome biogenesis and miRNA cargo sorting via regulation of YBX1 gene expression.
