Abstract
MiRNAs could play an important role in tumorigenesis and progression. The oncoprotein MDM2 (murine double minute 2) was identified as a negative regulator of the tumour suppressor p53. This study aims to analyse the expression of the MDM2 target miRNA candidates (miR-3613-3p, miR-371b-5p and miR-3658) and the MDM2 gene in oral squamous cell carcinoma tumour and margin samples and their association with the selected socio-demographic and clinicopathological characteristics. The study group consisted of 50 patients. The miRNAs and MDM2 gene expression levels were assessed by qPCR. The expression analysis of the miRNAs showed the expression of only one of them, i.e., miR-3613-3p. We found no statistically significant differences in the miR-3613-3p expression in tumour samples compared to the margin samples. When analysing the effect of smoking on miR-3613-3p expression, we demonstrated a statistically significant difference between smokers and non-smokers. In addition, we showed an association between the miR-3613-3p expression level and some clinical parameters in tumour samples (T, N and G). Our study demonstrates that miR-3613-3p overexpression is involved in the tumour progression of OSCC. This indicates that miR-3613-3p possesses potential prognostic values.

Abstract
The pluripotency factor, OCT4 gene is a stemness marker that is involved in the tumorigenicity of different cancer types and knowing about molecular mechanisms of its regulation is crucially important. To date, a few microRNAs (miRNAs) are known to be regulators of OCT4 gene expression. Looking for the novel miRNAs which are capable of regulating OCT4 gene expression, our bioinformatics analysis introduced hsa-miR-3658 (miR-3658) as a bona fide candidate. Then, RT-qPCR results indicated that miR-3658 expression is decreased in colorectal cancer (CRC) tumor tissues, compared with normal pairs. Furthermore, RT-qPCR and western blot analysis showed that the OCT4 gene has been down-regulated following the miR-3658 overexpression. Consistently, dual-luciferase assay supported the direct interaction of miR-3658 with the 3'-UTR sequence of OCT4 gene. Unlike in HCT116 cells, overexpression of miR-3658 in SW480 cells brought about growth inhibition, cell cycle arrest and reduced cell migration, detected by flow cytometry, and scratch test assay. Overall, these findings demonstrated that miR-3658 as a tumor suppressor miRNA exerts its effect against OCT4 gene expression, and it has the potential of being used as a prognostic marker and therapeutic target against colorectal cancer.

Abstract
Osteogenic differentiation of dental pulp stem cells (DPSCs) is considered as a promising strategy in posterior maxilla tooth implantation. Information on the function and mechanisms of long non-coding RNAs (lncRNAs) in osteogenic differentiation of DPSCs is growing, however, the mechanism of LINC00968 and miR-3658 in regulating osteogenic differentiation of DPSCs still needs to be explored. In this study, the LINC00968 and miR-3658 expression level was upregulated and downregulated in DPSCs and peri-implantitis DPSCs (pDPSCs) treated with bone morphogenic protein (BMP)2, respectively. Moreover, the effects of LINC00968 and miR-3658 on BMP2-induced osteogenic differentiation of DPSCs in vitro using Alizarin Red S staining, alkaline phosphatase (ALP) activity, quantitative real time PCR and Western blot assays showed that overexpression of LINC00968 significantly promoted mineralized bone matrix, alkaline phosphatase (ALP), runt-related transcription factor 2 (RUNX2), and osterix (OSX) expression levels for osteogenic differentiation of DPSCs and pDPSCs; and overexpression of miR-3658 showed an opposite result that inhibited osteogenic differentiation of DPSCs and pDPSCs. Luciferase reporter assay showed that luciferase activities of LINC00968-WT reporter and RUNX2-WT reporter were strongly suppressed by miR-3658 overexpression. In addition, the miR-3658 upregulation interfered ectopic bone formation in vivo stimulated by LINC00968. In general, we had identified a novel molecular pathway involving LINC00968/miR-3658/RUNX2 during DPSCs and pDPSCs differentiation into osteoblasts, which might facilitate bone anabolism.
