Abstract

The human Periodontal Ligament Stem Cells (hPDLSCs) exhibit self-renewal capacity and clonogenicity potential. The Extracellular Vesicles (EVs) secreted by hPDLSCs are particles containing lipids, proteins, mRNAs, and non-coding RNAs, among which microRNAs, that are important in intercellular communication. The purpose of this study was the analysis of the non-coding RNAs contained in the EVs derived from hPDLSCs using Next Generation Sequencing. Moreover, our data were enriched using bioinformatic tools. The analysis highlighted the presence of non-coding RNAs and five microRNAs: MIR24-2, MIR142, MIR335, MIR490, and MIR296. Our results show that these miRNAs target the genes classified in two terms of the Gene Ontology: "Ras protein signal transduction" and "Actin/microtubule cytoskeleton organization." Noteworthy, the in-deep analysis of our EVs highlights that the miRNAs could be implicated in the silencing of proto-oncogenes involved in 12 different types of tumors.

Keywords: cytokinesis; extracellular vesicles; human periodontal ligament stem cells; microRNAs; next generation sequencing; non-coding RNAs.

Representation of the biological processes in which the genes targeted by the miRNAs in EVs are mainly involved. The miRNAs MIR24, MIR142, MIR335, MIR296, and MIR490 mainly target genes belonging to the “Cellular processes” category of the Gene Ontology. More specifically, the genes fall into two sub-categories “Ras protein signal transduction” and “Actin/microtubule cytoskeleton organization.” The genes involved in these subprocesses are characteristic of the pathways represented in the outer ring.
