Abstract This study was designed to investigate the role of miR-183 in modulating cell growth and apoptosis of tongue squamous cell carcinoma SCC25 cell line. Human squamous epithelial cell and squamous cell carcinoma cell line SCC25 was used, and miR-183 was inhibited. Cell growth, colony formation, and apoptotic rate, as well as the expression of caspase 3 and BCL-xL, were detected. Results showed that miR-183 was significantly overexpressed in the SCC25 cell line when compared with normal control. The miR-183 inhibitor reduced cell growth and colony formation, while the apoptosis percentage was significantly increased. The expression More >

Abstract Acute lymphoblastic leukemia (ALL) is the most common childhood malignancy and causes a high rate of mortality in affected adults. Many subtypes of ALL exist with disruptions in distinct genetic pathways, including those regulated by miRNAs. Here we identify miR-187-5p as being highly upregulated in B-cell ALL and a driver of cellular proliferation and suppressor of apoptosis. We show that miR-187-5p directly targets the 3'-UTR of DKK2 to mediate these effects. We further determine that inhibition of DKK2 by miR-187-5p in Nalm-6 B cells leads to inappropriate activation of Wnt/β-catenin signaling. Together, these findings reveal More >

Abstract Procaine (PCA) is a conventional chemotherapeutic agent for osteosarcoma. Recent studies have proposed that the growth-inhibitory effect of PCA is through regulation of microRNAs (miRNAs). miR-133b has been proven to be a tumor suppressor in osteosarcoma, but whether it is involved in the antitumor effects of PCA on osteosarcoma has not been investigated. In this study, we aimed to explore the effects of PCA on osteosarcoma MG63 cells by regulation of miR-133b, as well as its underlying mechanisms. MG63 cells were treated with different concentrations of PCA, and cell viability, apoptosis, and miR-133b expression were… More >

Abstract Some microRNAs (miRs) have been demonstrated to play promoting or tumor-suppressing roles in the development and progression of hepatocellular carcinoma (HCC). However, the regulatory mechanism of miR-98-5p in HCC still remains largely unclear. In the present study, our data showed that miR-98-5p was significantly downregulated in 84 cases of HCC tissues compared to the matched adjacent nontumor tissues. In addition, downregulation of miR-98-5p was associated with tumor size, portal vein tumor embolus, node metastasis, and clinical stage in HCC. HCC patients with low expression of miR-98-5p showed a shorter survival time compared with those with… More >

Abstract Choriocarcinoma is one of the gestational trophoblastic neoplasias (GTNs) that originate in the chorionic villi and the extravillous trophoblast. Long noncoding RNAs (lncRNAs) are a type of non-protein-coding RNAs that have recently been implicated in human tumorigenesis. The present study investigated the role of the lncRNA LINC00261 in cell proliferation, metastasis, and apoptosis in choriocarcinoma cell lines. The transcription level of LINC00261 was significantly lower in choriocarcinoma tissues and in choriocarcinoma cell lines. Overexpression of LINC00261 caused a decrease in cell proliferation and arrested the cell cycle at the G₀/G₁ phase. Furthermore, overexpression of LINC00261 inhibited More >

Abstract Cervical cancer is one of the most common cancers in females, with a high incidence and mortality around the world. However, the pathogenesis in cervical cancer is not completely known. In the present study, we investigated the role of miR-126-5p and Bcl2l2 in cervical cancer cells. First, miR-126-5p expression was aberrantly downregulated in human cervical cancer tumor tissues in comparison with normal tissues, as evaluated by RT-PCR. Consistently, the levels of miR-126-5p were also significantly reduced in cervical cancer cell lines when compared to normal cervical epithelial cells. Flow cytometric analysis showed that the rate… More >

Abstract Esophageal squamous cell carcinoma (ESCC) is one of the most common malignant cancers with high mortality around the world. However, the regulatory mechanism of ESCC carcinogenesis is not completely known. Here we demonstrate the novel role of miR-202 in regulating ESCC cell apoptosis. The analysis of data obtained from the GEO database showed that the expression of miR-202 is aberrantly decreased in tumor tissue from ESCC patients and cultured ESCC cell lines. After transfection with miR-202 mimic or inhibitor, the apoptotic capacity of ESCC cells was significantly increased by miR-202 overexpression but reduced by miR-202… More >

Abstract Ovarian cancer remains as one of the most threatening malignancies for females in the world. This study investigated the pivotal role of miR-940 in the progression of ovarian cancer and to reveal the possible molecular mechanism of its action. Ovarian cancer OVCAR3 cells were transfected with the miR-940 vector, miR-940 inhibitor, and/or small interfering RNA (siRNA) targeting PKC-d (si-PKC-δ), respectively. After transfection, cell viability and cell apoptosis were analyzed, as well as cell proliferation and apoptosis-related protein expression. Compared to the control, miR-940 upregulation suppressed cell viability but induced cell apoptosis. miR- 940 upregulation increased… More >
