Abstract
BACKGROUND Oral squamous cell carcinoma (OSCC) is a common malignant tumor associated with poor prognosis. MicroRNAs (miRNAs) play crucial regulatory roles in the cancer development. However, the role of miRNAs in OSCC development and progression is not well understood. METHODS We sought to establish a dynamic Chinese hamster OSCC animal model, construct miRNA differential expression profiles of its occurrence and development, predict its targets, and perform functional analysis and validation in vitro. RESULTS Using expression and functional analyses, the key candidate miRNA (miR-181a-5p) was selected for further functional research, and the expression of miR-181a-5p in OSCC tissues and cell lines was detected. Subsequently, transfection technology and a nude mouse tumorigenic model were used to explore potential molecular mechanisms. miR-181a-5p was significantly downregulated in human OSCC specimens and cell lines, and decreased miR-181a-5p expression was observed in multiple stages of the Chinese hamster OSCC animal model. Moreover, upregulated miR-181a-5p significantly inhibited OSCC cell proliferation, colony formation, invasion, and migration; blocked the cell cycle; and promoted apoptosis. BCL2 was identified as a target of miR-181a-5p. BCL2 may interact with apoptosis- (BAX), invasion- and migration- (TIMP1, MMP2, and MMP9), and cell cycle-related genes (KI67, E2F1, CYCLIND1, and CDK6) to further regulate biological behavior. Tumor xenograft analysis indicated that tumor growth was significantly inhibited in the high miR-181a-5p expression group. CONCLUSION Our findings indicate that miR-181a-5p can be used as a potential biomarker and provide a novel animal model for mechanistic research on oral cancer.

Huang S, Chen M, Yu H, Lin K, Guo Y, Zhu P. Co‑expression of tissue kallikrein 1 and tissue inhibitor of matrix metalloproteinase 1 improves myocardial ischemia‑reperfusion injury by promoting angiogenesis and inhibiting oxidative stress. Mol Med Rep 2020; 23:166. [PMID: 33355364 PMCID: PMC7789088 DOI: 10.3892/mmr.2020.11805] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2020] [Accepted: 11/23/2020] [Indexed: 11/05/2022] Open
Abstract
Myocardial ischemia/reperfusion (I/R) injury is a serious complication of reperfusion therapy for myocardial infarction. At present, there is not an effective treatment strategy available for myocardial I/R. The present study aimed to investigate the effects of human tissue kallikrein 1 (hTK1) and human tissue inhibitors of matrix metalloproteinase 1 (hTIMP1) gene co‑expression on myocardial I/R injury. A rat model of myocardial I/R injury and a cell model with hypoxia/reoxygenation (H/R) treatment in cardiac microvascular endothelial cells (CMVECs) were established, and treated with adenovirus (Ad)‑hTK1/hTIMP1. Following which, histological and triphenyl‑tetrazolium‑chloride staining assays were performed. Cardiac function was tested by echocardiographic measurement. The serum levels of oxidative stress biomarkers in rats and the intracellular reactive oxygen species (ROS) levels in CMVECs were measured. Additionally, experiments, including immunostaining, reverse transcription‑quantitative PCR, western blotting, and MTT, wound healing, Transwell and tube formation assays were also performed. The results of the present study demonstrated that Ad‑hTK1/hTIMP1 alleviated myocardial injury and improved cardiac function in myocardial I/R model rats. Ad‑hTK1/hTIMP1 also significantly enhanced microvessel formation, decreased matrix metalloproteinase (MMP)2 and MMP9 expression, and reduced oxidative stress in myocardial I/R model rats. Furthermore, Ad‑hTK1/hTIMP1 significantly enhanced proliferation, migration and tube formation in H/R‑treated CMVECs. Additionally, Ad‑hTK1/hTIMP1 significantly decreased intracellular ROS production and γ‑H2A.X variant histone expression levels in H/R‑treated CMVECs. In conclusion, the results of the present study demonstrated that co‑expression of hTK1 and hTIMP1 genes displayed significant protective effects on myocardial I/R injury by promoting angiogenesis and suppressing oxidative stress; therefore, co‑expression of hTK1 and hTIMP1 may serve as a potential therapeutic strategy for myocardial I/R injury.

TIMP-1 inhibits proliferation and osteogenic differentiation of hBMSCs through Wnt/β-catenin signaling. Biosci Rep 2019; 39:BSR20181290. [PMID: 30473539 PMCID: PMC6328886 DOI: 10.1042/bsr20181290] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2018] [Revised: 11/03/2018] [Accepted: 11/19/2018] [Indexed: 01/01/2023] Open
Abstract
The present study aimed to evaluate the effect of tissue inhibitor of metalloproteinase-1 (TIMP-1) on the proliferation and osteogenic differentiation potential of human bone marrow-derived MSCs (hBMSCs). hBMSCs with stable TIMP-1 overexpression or TIMP-1 knockdown were generated. Osteogenic differentiation was assessed by Alizarin Red S staining, alkaline phosphatase (ALP) activity and expression of specific markers. Compared with the vehicle controls, TIMP-1 knockdown significantly promoted the growth of hBMSCs. TIMP-1 knockdown up-regulated β-catenin and cyclin D1 proteins. During osteogenic differentiation, TIMP-1 knockdown elevated the deposition of calcium nodules, ALP activity and the mRNA levels of the osteogenic markers sex determining region Y-box 9 (Sox9), CCAAT-enhancer-binding protein and peroxisome proliferator-activated receptor γ. During osteogenic differentiation, TIMP-1 knockdown significantly enhanced the up-regulation of osteocalcin proteins. Meanwhile, TIMP-1 overexpression attenuated the Wnt/activator Wnt3a-induced up-regulation cyclin D1 and Runt-related transcription factor 2 (RUNX-2) (during osteogenic differentiation) proteins, while TIMP-1 knockdown restored the inhibitor Dickkopf 1-induced inhibition effect on the expression of β-catenin, cyclin D1 and RUNX-2. TIMP-1 plays a negative regulatory role in the proliferation and osteogenesis of hBMSCs, at least partially, through Wnt/β-catenin signaling.
