Background: Recent studies revealed that the hypoglycemic hormone, glucagon-like
peptide-1 (GLP-1), acted as an important modulator in osteogenesis of bone marrow derived
mesenchymal stem cells (BMSCs).
Objectives: The aim of this study was to identify the specific microRNA (miRNA) using
bioinformatics analysis and validate the presence of differentially expressed microRNAs with their
target genes after GLP-1 receptor agonist (GLP-1RA) administration involved in osteogenesis of
Methods: MiRNAs were extracted from BMSCs after 5 days’ treatment and sent for highthroughput
sequencing for differentially expressed (DE) miRNAs analyses. Then, the expression
of the DE miRNAs was verified by the real-time RT-PCR analyses. Target genes were predicted,
and highly enriched GOs and KEGG pathway analysis were conducted using bioinformatics
analysis. For the functional study, two of the target genes, SRY (sex determining region Y)-box 5
(SOX5) and G protein-coupled receptor 84 (GPR84), were identified.
Results: A total of 5 miRNAs (miRNA-509-5p, miRNA-547-3p, miRNA-201-3p, miRNA-201-5p,
and miRNA-novel-272-mature) were identified and differentially expressed among groups. The
expression of miRNA-novel-272-mature was decreased during the osteogenic differentiation of
BMSCs, and GLP-1RA further decreased its expression. MiRNA-novel-272-mature might interact
with its target mRNAs to enhance osteogenesis. The lower expression of miRNA-novel-272-
mature led to an increase in SOX5 and a decrease in GPR84 mRNA expression, respectively.
Conclusion: Taken together, these results provide further insights to the pharmacological
properties of GLP-1RA and expand our knowledge on the role of miRNAs-mRNAs regulation
network in BMSCs’ differentiation.
