Abstract Propofol has been widely used in lung cancer resections. Some studies have demonstrated that the effects of propofol might be mediated by microRNAs (miRNAs). This study aimed to investigate the effects and mechanisms of propofol on lung cancer cells by regulation of miR-1284. A549 cells were treated with different concentrations of propofol, while transfected with miR-1284 inhibitor, si-FOXM1, and their negative controls. Cell viability, migration, and invasion, and the expression of miR-1284, FOXM1, and epithelial–mesenchymal transition (EMT) factors were detected by CCK-8, Transwell, qRT-PCR, and Western blot assays, respectively. In addition, the regulatory and binding relationships among propofol, miR-1284, and… More >

Abstract The dysregulation of microRNAs (miRNAs) plays an important function in the onset and progression of gastric cancer (GC). In addition, aberrantly expressed miRNAs affect the chemosensitivity of GC cells to chemotherapeutic drugs. Hence, miRNA-based targeted therapy might be applied to treat patients with GC exhibiting chemotherapeutic resistance. In this study, miRNA-623 (miR-623) expression was downregulated in GC tissues and cell lines. Functional analysis showed that the restored miR-623 expression could inhibit the proliferation of GC cells and enhance their chemosensitivity to 5-FU via the cell apoptosis pathway. Cyclin D1 (CCND1) was identified as a direct target gene of miR-623 in… More >

Abstract Artemis is a key protein of NHEJ (nonhomologous end joining), which is the major pathway for the repair of IR-induced DSBs in mammalian cells. However, the expression of Artemis in tumors and the influence of silencing Artemis on tumor sensitivity to radiation have not been investigated fully. In this study, we investigated how the expression levels of Artemis may affect the treatment outcome of radiotherapy and chemotherapy in colorectal cancer cells. First, we found that the expression of Artemis is strong in some human rectal cancer samples, being higher than in adjacent normal tissues using immunohistochemical staining. We then knocked… More >

Abstract Long noncoding RNAs (lncRNAs) have been reported to play important roles in tumorigenesis. In the present study, we demonstrated that lncRNA forebrain embryonic zinc finger protein 1 (FEZF1) antisense RNA1 (FEZF1-AS1) is markedly upregulated in human lung adenocarcinoma (LAD) tissues and cell lines and is associated with poor prognosis. Loss of function revealed that deletion of FEZF1-AS1 expression significantly inhibited the LAD cell proliferation, invasion, and migration. Further studies revealed that downregulation of FEZF1-AS1 reduced mRNA and protein expression of its sense-cognate gene FEZF1 in LAD cells, and vice versa. Correlation analysis indicated that there was a positive correlation between… More >

Abstract Non-small cell lung cancer (NSCLC) represents the leading cause of cancer-related mortality worldwide. More and more reports have identified important roles for long noncoding RNAs (lncRNAs) in cancer development. ENST457720 expression was upregulated in lung adenocarcinoma in a microarray-based lncRNA screen. We determined the expression levels of ENST457720 in NSCLC tissues with quantitative real-time PCR and then studied their clinical significance. We explored the biological significance of ENST457720 with gain- and lossof-function analyses in vitro and in vivo. In this study, ENST457720 was expressed at higher levels in NSCLC tissues than in paired normal tissues. Higher ENST457720 expression was associated… More >

Abstract MicroRNAs (miRNAs) have been demonstrated to be essential regulators in the development and progression of various cancers. The role of miR-188-5p in gastric cancer (GC) has not been determined. In this study, we found that the expression of miR-188-5p was downregulated in GC tissues compared with adjacent normal tissues. The lowly expressed miR-188-5p was significantly associated with lymph node metastasis and advanced TNM stage. Moreover, overexpression of miR-188-5p significantly inhibited GC cell proliferation, migration, and invasion but promoted cellular apoptosis. Mechanistically, we identified transcription factor ZFP91 as a target gene of miR-188-5p in GC. We found that miR-188-5p overexpression significantly… More >

Abstract Laryngeal carcinoma is a type of head and neck carcinoma with a high incidence and mortality. Chemotherapy treatments of human laryngeal carcinoma may fail due to the development of chemoresistance. Tissue inhibitor of metalloproteinase 3 (TIMP-3) has been shown to be implicated in a number of pathological processes typical for cancer. The present study aims to investigate the involvement of TIMP-3 in the chemoresistance of laryngeal carcinoma. We showed that TIMP-3 expression was significantly decreased in chemoresistant laryngeal carcinoma tissues compared with chemosensitivity tissues. Patients with low TIMP-3 expression exhibited poorer overall survival than those with high TIMP-3 expression. Moreover,… More >

Abstract This study investigated the tumor-suppressive role of miR-148b in regulating endoplasmic reticulum metalloprotease 1 (ERMP1) expression and the oxidative stress response in endometrial cancer cells. Human endometrial cancer RL95-2 cells were used and transfected with miR-148b mimic, miR-148b inhibitor, or their scrambled negative control. Thereafter, the transfection efficiency was determined by RT-qPCR, and cell proliferation was assessed by MTT assay. The dual-luciferase reporter assay, Western blot, and RT-qPCR were conducted to determine the target gene of miR-148b. ERMP1 is a putative target of miR-148b, and thereby the overexpression and downregulation of ERMP1 on the proliferation of RL95-2 cells were assessed.… More >

Abstract Osteosarcoma is the most common primary malignant bone tumor in children and adolescents. This study aimed to explore the effects of long noncoding RNA CAT104 and microRNA-381 (miR-381) on osteosarcoma cell proliferation, migration, invasion, and apoptosis, as well as the underlying potential mechanism. We found that CAT104 was highly expressed in osteosarcoma MG63 and OS-732 cells. Knockdown of CAT104 significantly inhibited OS-732 cell proliferation, migration, and invasion, but promoted cell apoptosis. CAT104 regulated the expression of miR-381, and miR-381 participated in the effects of CAT104 on OS-732 cells. Zinc finger E-box-binding homeobox 1 (ZEB1) was a direct target gene of… More >

Abstract We aimed to investigate the significant role of long noncoding RNA X inactive specific transcript (XIST) in regulating tumor metastasis in colorectal cancer (CRC), as well as its possible mechanism. Expression of lncRNA XIST in CRC tissues and CRC cells was detected. CRC cells were transfected with pc-XIST, blank control si-XIST, or si-control, and then the effects of lncRNA XIST on CRC cell migration and invasion were investigated, along with the interaction between lncRNA XIST and miR-137. lncRNA XIST was upregulated in CRC tissues. Compared with HT29 cells that had low metastatic potential, XIST was markedly more highly expressed in… More >

Abstract MicroRNA-338-3p (miR-338-3p) has been reported to be a tumor suppressor in multiple cancer types. However, the biological role of miR-338-3p and its underlying mechanism in multiple myeloma (MM) remain unclear. In the present study, we investigated the biological role and potential of miR-338-3p in MM. We found that miR-338-3p was significantly decreased in newly diagnosed and relapsed MM tissues and cell lines. Overexpression of miR-338-3p in MM cells significantly inhibited proliferation and promoted apoptosis, caspase 3, and caspase 8 activity. Bioinformatics algorithm analysis predicted that cyclin-dependent kinase 4 (CDK4) was a direct target of miR-338-3p, and this was experimentally verified… More >

Abstract KIFC1 (kinesin family member C1) plays a critical role in clustering of extra centrosomes in various cancer cells and thus could be considered as a promising therapeutic target. However, whether KIFC1 is involved in the procession of renal cell carcinoma (RCC) still remains unclear. In this study, we found that KIFC1 was upregulated in RCC tissues and is responsible for RCC tumorigenesis (p<0.001). The high expression of KIFC1 correlates with aggressive clinicopathologic parameters. Kaplan–Meier analysis suggested that KIFC1 was associated with poor survival prognosis in RCC. Silencing KIFC1 dramatically resulted in inhibition of proliferation, delayed the cell cycle at G₂/M… More >
