miR-136 Inhibits Malignant Progression of Hepatocellular Carcinoma Cells by Targeting Cyclooxygenase 2

MicroRNAs (miRNAs) play a vital role in regulating tumor progression. Dysregulated miR-136 expression was linked to the development of various human cancers. In the present study, we investigated the expression and relationship of miR-136 and COX2 in hepatocellular carcinoma (HCC) using relevant experiments, involving CCK-8, Transwell assay, and luciferase reporter assay. We demonstrated that miR-136 expression is obviously decreased in HCC tissues and cells, and negatively correlated with the expression of COX2 mRNA. In vitro assay revealed that overexpression of miR-136 significantly changed the expression of proliferation- and metastasis-related proteins and inhibited the proliferation, migration, and invasion of HepG2 and Hep3B cells. Dual-luciferase reporter assay validated that the 3′-untranslated region (3′-UTR) of COX2 is a direct target of miR-136. Furthermore, COX2 siRNA partially enhanced the miR-136 overexpression-induced inhibitory effects. In conclusion, miR-136 was vital in the regulation of HCC cell proliferation and metastasis by targeting COX2. Thus, our findings provided novel evidence that miR-136 might be recommended as a potential target for the diagnosis and treatment of HCC patients.

Abstract Background: Long non-coding RNAs (lncRNAs) have obtained growing attention due to their potential effects as novel regulators in various tumors. This study aimed to investigate the expression and roles of lncRNA ZFPM2-AS1 in the progression of hepatocellular carcinoma (HCC). Methods: Transwell was used to determine migration and invasion of HCC cells in vitro. The lung metastasis mouse model was established to detect tumor metastasis of HCC in vivo. The direct binding of miR-3612 to 3'UTR of DAM15 was confirmed by luciferase reporter assay. The expression of ZFPM2-AS1 and miR-3612 in HCC specimens and cell lines were detected by real-time PCR. The correlation among ZFPM2-AS1 and miR-3612 were disclosed by a dual-luciferase reporter assay, RIP assay and biotin pull-down assay.Results: In present study, we found that ZFPM2-AS1 was up-regulated in HCC tissues and cells and its upregulation was associated with TNM stage, vascular invasion, and poor prognosis of HCC patients. Functionally, gain- and loss-of-function experiments indicated that ZFPM2-AS1 promoted cell migration, invasion and EMT progress in vitro and in vivo. ZFPM2-AS1 could function as a competing endogenous RNA (ceRNA) by sponging miR-3612 in HCC cells. Mechanically, miR-3612 inhibited HCC metastasis and alternation of miR-3612 reversed the promotive effects of ZFPM2-AS1 on HCC cells. In addition, we confirmed that ADAM15 was a direct target of miR-3612 in HCC and mediated the biological effects of miR-3612 and ZFPM2-AS1 in HCC. Curcumin, an active derivative from turmeric, exerts its anticancer effects through ZFPM2-AS1/miR-3612/ADAM15 pathway. Our data identified ZFPM2-AS1 as a novel oncogenic lncRNA and correlated malignant clinical outcomes in HCC patients. Conclusions: ZFPM2-AS1 performed as oncogenic role via targeting miR-3612 and subsequently promoted ADAM15 expression in HCC. Our results revealed that ZFPM2-AS1 could be a potential prognostic biomarker and therapeutic target for HCC.

Background/Aims: Previous studies have demonstrated that long non-coding RNAs (lncRNAs) may play critical roles in cancer biology, including Hepatocellular carcinoma (HCC). The HOXA cluster antisense RNA2 (HOXA-AS2) lncRNA plays an important role in carcinogenesis, however, the underlying role of HOXA-AS2 in HCC remains unknown. The present study examined the effects of HOXA-AS2 on the progression of HCC, and explored the underlying molecular mechanisms. Methods: Quantitative real-time PCR was used to detect HOXA-AS2 expression in HCC tissues and cell lines. Furthermore, the effects of HOXA-AS2 silencing and overexpression on cell proliferation, cell cycle, apoptosis, migration, and invasion were assessed in HCC in vitro and in vivo. Furthermore, bioinformatics online programs predicted and luciferase reporter assay were used to validate the association of HOXA-AS2 and miR-520c-3p in HCC cells. Results: We observed that HOXA-AS2 was up-regulated in HCC tissues and cell lines. In vitro experiments revealed that HOXA-AS2 knockdown significantly inhibited HCC cells proliferation by causing G1 arrest and promoting apoptosis, whereas HOXA-AS2 overexpression promoted cell growth. Further functional assays indicated that HOXA-AS2 significantly promoted HCC cell migration and invasion by promoting EMT. Bioinformatics online programs predicted that HOXA-AS2 sponge miR-520c-3p at 3’-UTR with complementary binding sites, which was validated using luciferase reporter assay. HOXA-AS2 could negatively regulate the expression of miR-520c-3p in HCC cells. MiR-520c-3p was down-regulated and inversely correlated with HOXA-AS2 expression in HCC tissues. miR-520c-3p suppressed cell proliferation, invasion and migration in HCC cells, and enforced expression of miR-520c-3p attenuated the oncogenic effects of HOXA-AS2 in HCC cells. By bioinformatic analysis and dual-luciferase reporter assay, we found that miR-223-3p directly targeted the 3’-untranslated region (UTR) of Glypican-3 (GPC3), one of the key players in HCC. GPC3 was up-regulated in HCC tissues, and was negatively correlated with miR-520c-3p expression and positively correlated with HOXA-AS2 expression. Conclusion: In summary, our results suggested that the HOXA-AS2/miR-520c-3p/GPC3 axis may play an important role in the regulation of PTC progression, which could serve as a biomarker and therapeutic target for HCC.

The expression of miR-126 and serine‐arginine protein kinase 1 (SRPK1) are linked to tumor development; nevertheless, its role in the tumor growth and invasion of gastric cancer (GC) and the underlying mechanism have not been clarified. Here the expression and role of miR-126 and SRPK1 were investigated in GC tissues and cells by in vitro assay, and then targets of miR-126 were identified by dual-luciferase reporter assay. In this study, miR-126 expression was downregulated and associated with lymph node metastasis and poor prognosis as well as SRPK1 expression. In vitro assay revealed that miR-126 obviously inhibited the proliferative and invasive capabilities of GC cells. The dual-luciferase reporter assay showed that miR-126 targets the 3′-UTR of SRPK1 and downregulates its expression. SRPK1 overexpression promoted cell migration and invasion. In conclusion, the reduced expression of miR-126 is suggestive of the risk of GC recurrence and metastasis, and miR-126 functions as a tumor suppressor by targeting SRPK1 expression in the development of GC.

Objective: LncRNAs are non-coding RNAs exerting vital roles in the occurrence and development of various cancer types. This study tended to describe the expression pattern of FENDRR in colorectal cancer (CRC), and further investigate the role of FENDRR in CRC cell biological behaviors. Methods: Gene expression profile of colon cancer was accessed from the TCGA database, and then processed for differential analysis for identification of differentially expressed lncRNAs and miRNAs. Some in vitro experiments like qRT-PCR, MTT, colony formation assay, wound healing assay and Transwell assay were performed to assess the effect of FENDRR on cell biological behaviors. Dual-luciferase reporter assay was conducted to further validate the targeting relationship between FENDRR and miR-424-5p, and rescue experiments were carried out for determining the mechanism of FENDRR/miR-424-5p underlying the proliferation, migration and invasion of CRC cells. Results: Bioinformatics analysis suggested that FENDRR was significantly down-regulated in CRC tissue, and low FENDRR was intimately correlated to poor prognosis. FENDRR overexpression could greatly inhibit cell proliferation, migration and invasion. Besides, there was a negative correlation between FENDRR and miR-424-5p. Dual-luciferase reporter assay indicated that miR-424-5p was a direct target of FENDRR. Rescue experiments discovered that FENDRR exerted its role in cell proliferation, migration and invasion in CRC via targeting miR-424-5p. Conclusion: FENDRR is poorly expressed in CRC tissue and cells, and low FENDRR is responsible for the inhibition of cell proliferation, migration and invasion of CRC by means of targeting miR-424-5p.

Background and Objective: Accumulating evidence supports that fibroblast-like synovial cells (FLS) plays a vital role in the pathogenesis of rheumatoid arthritis (RA). miR-1246 has been reported to be up-regulated in the sera of RA patients. The purpose of the present research was to determine the potential role of miR-1246 in RA and the underlying mechanisms. Methods: miR-1246, GSK3β and AXIN2 levels were determined by RT-qPCR. By exploiting miR-1246 inhibitor, shRNA-GSK3β and shRNA-AXIN2, we detected the effects of miR-1246, GSK3β and AXIN2 on cell proliferation, apoptosis and inflammation in RA-FLSs. Bioinformatics analysis predicted the binding sites of miR-1246 to AXIN2, miR-1246 to GSK3β. Moreover, luciferase reporter assay verified the binding relationship. Results: In comparison with normal human FLSs, higher levels of miR-1246 existed in RA-FLSs. Downregulation of miR-1246 inhibited cell proliferation, inflammation and β-catenin expression, and promoted cell apoptosis. Furthermore, bioinformatic analysis and dual-luciferase reporter assay identified AXIN2 or GSK3β as a target gene of miR-1246. Downregulation of miR-1246 enhanced AXIN2 and GSK3β expression in RA-FLSs. Besides, co-transfection with shRNA-GSK3β or shRNA-AXIN2 partly reversed the regulatory effects of miR-1246 inhibitor in RA-FLSs. Conclusions: Collectively, our in vitro experiments proved that downregulation of miR-1246 might alleviate RA pathogenesis by targeting AXIN2 and GSK3β via Wnt/β-Catenin axis.

Abstract Background Accumulating data have established that microRNAs (miRNAs) play significant regulatory roles in the carcinogenesis and progression of ovarian cancer (OC). MiR-425-5p was reported to function in various tumors. However, the roles and underlying mechanism of miR-425-5p involvement in OC development and progression are unclear. Methods A comprehensive strategy of data mining, computational biology, and real-time polymerase chain reaction was employed to identify the involvement of miR-425-5p in OC progression. The effect of miR-425-5p on the proliferation, migration, and invasion of OC cells was determined using Cell Counting Kit-8, wound-healing, and Matrigel invasion assays, respectively. Luciferase assay was performed to evaluate the interactions between miR-425-5p and MAGI2-AS3 or AFF4. Results miR-425-5p was significantly up-regulated in OC tissues and cells. The luciferase reporter assay revealed that miR-425-5p was negatively regulated by MAGI2-AS3. Silencing miR-425-5p inhibited the proliferation, migration, and invasion of OC cells in vitro. Bioinformatics analysis and luciferase reporter assay revealed that AFF4 was the target gene of miR-425-5p. Moreover, AFF4 expression was significantly decreased in OC and was closely related to the good prognosis of patients with OC. AFF4 overexpression inhibited the proliferation, migration, and invasion of OC cells in vitro. By contrast, silencing AFF4 promoted the proliferation, migration, and invasion of OC cells in vitro. Finally, AFF4 suppression rescued the inhibitory effect of silencing miR-425-5p on the proliferation, migration, and invasion of OC cells. Conclusion To the best our knowledge, this is the first study to demonstrate that miR-425-5p overexpression in OC is negatively regulated by MAGI2-AS3. Moreover, miR-425-5p promotes the proliferation, migration, and invasion of OC cells by targeting AFF4, suggesting that miR-425-5p/AFF4 signaling pathway represented a novel therapeutic target for patients with OC.

Abstract Background: Hepatocellular carcinoma (HCC) is a common malignancy of the digestive system. A novel long non-coding RNA, ENSG00000236199 (lncRNA-199) , whose role in tumors has not been reported, especially in HCC. Methods: The expression of lncRNA-199 and miR-576-5p were detected by Real-time quantitative polymerase chain reaction (RT-qPCR), NRIP1 was measured by Western blotting. HCC cell proliferation and metastasis of HCC were examined using functional tests. Luciferase reporter assay was performed to confirm the relationship between lncRNA-199 and miR-576-5p, between miR-576-5p and NRIP1. Results: LncRNA-199 was frequently down-regulated in HCC and this down-regulation was negatively correlated with prognosis. Overexpression of lncRNA-199 could inhibit the growth and metastasis of HCC, while knockdown lncRNA-199 had the opposite effect. Down-regulated lncRNA-199 also could induce epithelial-mesenchymal transformation (EMT). Luciferase reporter assay demonstrated lncRNA-199 could modulate NRIP1 by sponge miR-576-5p. Conclusion: LncRNA-199 inhibited growth and metastasis through miR-576-5p/NRIP1 axis in HCC. This study revealed a novel unknown lncRNA function in malignant tumors, especially in HCC. At the same time, the regulatory mechanism of lncRNA-199 in HCC was clarified.

Objective: We aimed to investigate the mechanism of the regulatory axis of miR-196b/AQP4 underlying the invasion and migration of lung adenocarcinoma (LUAD) cells. Methods: LUAD miRNA and mRNA expression profiles were downloaded from TCGA database and then differential analysis was used to identify the target miRNA. Target gene for the miRNA was obtained via prediction using 3 bioinformatics databases and intersection with the differentially expressed mRNAs searched from TCGA-LUAD. Then, qRT-PCR and western blot were used to validate the expression of miR-196b and AQP4. Dual-luciferase reporter assay was performed to confirm the targeting relationship between miR-196b and AQP4. Transwell assay was used to investigate the migration and invasion of LUAD cells. Results: MiR-196b was screened out by differential and survival analyses, and the downstream target gene AQP4 was identified. In LUAD, miR-196b was highly expressed while AQP4 was poorly expressed. Besides, overexpression of miR-196b promoted cell invasion and migration, while overexpression of AQP4 had negative effects. Moreover, the results of the dual-luciferase reporter assay suggested that AQP4 was a direct target of miR-196b. In addition, we also found that overexpressing AQP4 could suppress the promotive effect of miR-196b on cancer cell invasion and migration. Conclusion: MiR-196b promotes the invasion and migration of LUAD cells by down-regulating AQP4, which helps us find new molecular targeted therapies for LUAD.

Acute Myeloid

Background/Aims: Among different molecular candidates, there is growing data to support that long noncoding RNAs (lncRNAs) play a significant role in acute myeloid leukemia (AML). HOXA-AS2 is significantly overexpressed in a variety of tumors and associated with anti-cancer drug resistance, however, little is known regarding the expression and function of HOXA-AS2 in the chemoresistance of AML. In this study, we aimed to determine the role and molecular mechanism of HOXA-AS2 in adriamycin-based chemotherapy resistance in AML cells. Methods: Quantitative real-time PCR was used to detect HOXA-AS2 expression in the BM samples and ADR cell lines, U/A and T/A cells. Furthermore, the effects of HOXA-AS2 silencing on cell proliferation and apoptosis were assessed in vitro by CCK8 and flow cytometry, and on tumor growth in vivo. Furthermore, bioinformatics online programs predicted and luciferase reporter assay were used to validate the association of HOXA-AS2 and miR-520c-3p in AML. Results: In this study, we showed that HOXA-AS2 is significantly upregulated in BM samples from AML patients after treatment with adriamycin-based chemotherapy and in U/A and T/A cells. Knockdown of HOXA-AS2 inhibited ADR cell proliferation in vitro and in vivo and promoted apoptosis. Bioinformatics online programs predicted that HOXA-AS2 sponge miR-520c-3p at 3’-UTR with complementary binding sites, which was validated using luciferase reporter assay and anti-Ago2 RIP assay. HOXA-AS2 could negatively regulate the expression of miR-520c-3p in ADR cells. S100A4 was predicted as a downstream target of miR-520c-3p, which was confirmed by luciferase reporter assay. Conclusion: Our results suggest that HOXA-AS2 plays an important role in the resistance of AML cells to adriamycin. Thus, HOXA-AS2 may represent a therapeutic target for overcoming resistance to adriamycin-based chemotherapy in AML.
