Abstract
Evidence has accumulated demonstrating that long noncoding RNAs (lncRNAs) participate in the initiation and progression of cancers. In this study, we found that the lncRNA nuclear paraspeckle assembly transcript 1 (NEAT1) is significantly increased in both cervical cancer tissues and cell lines. Overexpression of NEAT1 promoted the proliferation and migration of cervical cancer cells. Molecular studies uncovered that NEAT1 functions as competitive endogenous RNA (ceRNA), binding the micro-RNA miR-9-5p and suppressing its expression. However, we consistently found that when NEAT1 was highly expressed, it attenuated the inhibitory effect of miR-9-5p on the expression of PTEN and POU2F1, which are the targets of miR-9-5p. Consistent with the negative regulation of NEAT1 on miR-9-5p, restoration of miR-9-5p inhibited the growth-promoting effects of NEAT1 on cervical cancer cells. Taken together, these results indicated that NEAT1 plays an important role in the regulation cervical cancer cell growth by targeting miR-9-5p. Our findings characterized the possible mechanism of NEAT1 in cervical cancer.

Abstract
CCEPR (cervical carcinoma expressed PCNA regulatory lncRNA) has been found to be upregulated and enhance cell proliferation in human cancers. However, the role of CCEPR in osteosarcoma remains to be discovered. In this study, we found CCEPR expression was elevated in osteosarcoma tissue specimens and cell lines compared with adjacent normal tissue specimens and osteoblast cell line, respectively. Meanwhile, osteosarcoma patients with advanced stage or tumor size greater than 8 cm had higher expression of CCEPR than patients with early stage or tumor size less than or equal to 8 cm, respectively. Survival analysis suggested that osteosarcoma patients with high CCEPR expression had a worse overall survival rate than those with low CCEPR expression. The in vitro study indicated that CCEPR positively regulated proliferating cell nuclear antigen (PCNA) expression in osteosarcoma cells and silencing of CCEPR inhibited osteosarcoma cell proliferation through decreasing PCNA expression. In conclusion, CCEPR is a potential prognostic predictor and functions as oncogenic long non-coding RNA (lncRNA) to regulate cell proliferation via PCNA in osteosarcoma.

Long non-coding RNA FAM83H-AS1 is regulated by human papillomavirus 16 E6 independently of p53 in cervical cancer cells. Sci Rep 2019; 9:3662.

Abstract
High-risk human papillomavirus (HPV) infection is one of the first events in the process of carcinogenesis in cervical and head and neck cancers. The expression of the viral oncoproteins E6 and E7 are essential in this process by inactivating the tumor suppressor proteins p53 and Rb, respectively, in addition to their interactions with other host proteins. Non-coding RNAs, such as long non-coding RNAs (lncRNAs) have been found to be dysregulated in several cancers, suggesting an important role in tumorigenesis. In order to identify host lncRNAs affected by HPV infection, we expressed the high-risk HPV-16 E6 oncoprotein in primary human keratinocytes and measured the global lncRNA expression profile by high-throughput sequencing (RNA-seq). We found several host lncRNAs differentially expressed by E6 including GAS5, H19, and FAM83H-AS1. Interestingly, FAM83H-AS1 was found overexpressed in HPV-16 positive cervical cancer cell lines in an HPV-16 E6-dependent manner but independently of p53 regulation. Furthermore, FAM83H-AS1 was found to be regulated through the E6-p300 pathway. Knockdown of FAM83H-AS1 by siRNAs decreased cellular proliferation, migration and increased apoptosis. FAM83H-AS1 was also found to be altered in human cervical cancer tissues and high expression of this lncRNA was associated with worse overall survival, suggesting an important role in cervical carcinogenesis.

Abstract
Plasmacytoma variability translocation 1 (PVT1), an oncogene, has been reported to be highly expressed in many tumors, including human glioma, gastric cancer, and non-small cell lung cancer. Functionally, it could also regulate the development of tumor cells. However, its specific roles and pathogenesis in human gliomas are still not clear. This study investigated the function and mechanism of PVT1 knockdown in the proliferation and malignant transformation of human gliomas. We first examined the expression levels of PVT1 and miR-424 in human glioma tissues and cell lines. We also used gene manipulation techniques to explore the effects of PVT1 knockdown on cell viability, migration, invasion, and miR-424. We found that PVT1 knockdown effectively inhibited cell viability, migration, and invasion of human glioma cells and increased miR-424 expression. Based on the negative correlation between PVT1 and miR-424, we then confirmed the direct interaction between PVT1 and miR-424 using RNA immunoprecipitation (RIP) and luciferase reporter assays. Further, we established a xenograft nude mouse model to determine the role and mechanism of PVT1 on tumor growth in vivo. In addition, PVT1 knockdown was shown to promote miR-424 in vivo. In summary, the present study demonstrated that PVT1 knockdown could negatively regulate miR-424 to inhibit human glioma cell activity, migration, and invasiveness. PVT1 knockdown could negatively regulate miR-424 to inhibit cellular activity, migration, and invasiveness in human gliomas, which explained the oncogenic mechanism of PVT1 in human gliomas. It also suggested that PVT1 might be a novel therapeutic target for human gliomas.

Abstract
Accumulating research works have reported that long noncoding RNAs (lncRNAs) are involved in various cancers, including cervical cancer. LncRNA DGCR5 has been identified in many cancers. However, the biological role of DGCR5 in cervical cancer remains barely known. We aimed to investigate the biological function of DGCR5 in cervical cancer progression. Here, in our current study, we observed that DGCR5 was downregulated in human cervical cancer cell lines (MS751, SiHa, HeLa, and HT-3) compared with the primary normal cervical squamous cells (NCSC1 and NCSC2). Then, DGCR5 was restrained by transfection with lenti-virus-short hairpin RNA (LV-shRNA) while induced by LV-DGCR5 in HeLa and C33A cells. Silence of DGCR5 obviously induced cervical cancer cell viability and cell proliferation. Reversely, upregulation of DGCR5 inhibited HeLa and C33A cell survival and proliferation. Furthermore, silencing of DGCR5 increased cervical cancer cell colony formation ability and decreased cell apoptosis, whereas its overexpression exhibited an opposite process. Moreover, DGCR5 suppressed migration and invasion capacity of cervical cancer cells. The Wnt signaling is integral in numerous biological processes. Here, we found that Wnt signaling was strongly activated in cervical cancer cells. Downregulation of DGCR5 contributed to cervical cancer progression by activating Wnt signaling. Subsequently, in vivo animal models were used to confirm that DGCR5 suppressed cervical cancer via targeting Wnt signaling. In conclusion, we reported that DGCR5 was involved in cervical cancer progression via modulating the Wnt pathway.

Abstract
Although growing evidence has demonstrated that the long non-coding RNA DLEU1 is involved in the progression of various cancers, its functional role and underlying mechanisms have not been explored in cervical cancer (CC). In this study, we found that DLEU1 was up-regulated in both CC tissues and CC cell lines, and overexpression of DLEU1 was significantly correlated with shorter patient survival. Knockdown of DLEU1 suppressed CC cell proliferation and invasion, whereas overexpression of DLEU1 promoted the proliferation and invasion of CC cells. Bioinformatics analysis was used to elucidate the potential correlation between DLEU1 and miR-381. Moreover, qRT-PCR analysis, luciferase reporter assay and RNA immunoprecipitation assay confirmed that DLEU1 inhibited the expression of miR-381, and revealed a direct interaction between DLEU1 and miR-381. In addition, we demonstrated that miR-381 directly targeted HOXA13 in CC cells. The restoration of HOXA13 expression reversed DLEU1 knockdown or miR-381 overexpression-mediated suppression of cell proliferation and invasion. These results suggested that DLEU1 can promote CC cell proliferation and invasion via the miR-381/HOXA13 axis.

Abstract
Cervical cancer remains a malignant type of tumor and is the fourth leading cause of cancer-related death among females. MALAT1 has been identified as a tumor oncogene in various cancers. Our present study aimed to explore the biological role of MALAT1 in cervical cancer. We observed that MALAT1 was significantly upregulated in human cervical cancer cell lines compared with the ectocervical epithelial cells. MALAT1 was repressed by transfection with LV-shMALAT1, whereas increased by LV-MALAT1 in HeLa and Caski cells. Silencing of MALAT1 obviously reduced cervical cell viability, induced cell apoptosis, and repressed cell invasion capacity. Conversely, overexpression of MALAT1 exhibited an opposite phenomenon. Furthermore, miR-429 was predicted as a direct target of MALAT1, and it was dramatically decreased in cervical cancer cells. It has been shown that miR-429 plays a crucial role in cervical cancer progression. In our current study, the targeting correlation between MALAT1 and miR-429 was confirmed by luciferase reporter assays and RIP experiments. Finally, in vivo animal models were established, and we indicated that MALAT1 inhibited cervical cancer progression via targeting miR-429. These findings revealed that MALAT1 can sponge miR-429 and regulate cervical cancer pathogenesis in vivo and in vitro. In conclusion, we indicated that the MALAT1/miR-429 axis was involved in cervical cancer development.

Abstract
BACKGROUND HOX transcript antisense RNA (HOTAIR) is a long non-coding RNA (lncRNA) widely involved in the progression of numerous malignancies. Whereas, the potential molecular mechanism of HOTAIR involved in cervical cancer progression is still needed to be elaborated. METHODS The expression of HOTAIR and miR-143-3p were detected in cervical cancer tissues and cells by qRT-PCR. MTT and flow cytometry analysis were performed to measure cell proliferation and apoptosis. Bioinformatics, Dual-Luciferase reporter and RIP were used to analyze the possible correlation between HOTAIR, miR-143-3p and BCL2. The expression of Bax and BCL2 was detected by western blot. Mice xenograft model was established to confirm the role of HOTAIR on tumor growth in vivo. RESULTS HOTAIR expression was elevated while miR-143-3p expression was reduced in cervical cancer tissues and cell lines. HOTAIR knockdown suppressed proliferation and enhanced apoptosis in cervical cancer cells. Moreover, HOTAIR could function as a sponge for miR-143-3p. The inhibitory effect of HOTAIR knockdown on cervical cancer cells growth was abolished following decrease of miR-143-3p expression. Furthermore, HOTAIR promoted BCL2 expression by modulating miR-143-3p. BCL2 overexpression attenuated the tumor-suppressive effect of miR-143-3p in cervical cancer. Finally, the carcinogenicity of HOTAIR was validated in mice. CONCLUSIONS HOTAIR promoted cervical cancer cell growth by modulating BCL2 via miR-143-3p, hinting a novel regulatory mechanism and potential therapeutic target in cervical cancer.

Abstract
Long non coding RNAs (lncRNAs) are involved in modulating the expression of other non-coding RNAs (ncRNA), such as microRNAs, or target proteins through the epigenetic, transcriptional, or post-transcriptional regulations. Genomic mutations in cancer reside inside regions that do not code for proteins and these regions are often transcribed into long non coding RNAs (lncRNAs). Emerging evidences have revealed an intense involvement of lncRNAs in the cancer development and progression. Recently, emerging evidences have depicted that the phytochemicals interact with lncRNAs to modulate their activities. Such findings are highly important for the identification of therapeutic strategies against diseases that are particularly associated with an aberrant lncRNA signaling. This review aims at deciphering the role of lncRNAs in the cancer development and progression, and their regulation by various phytochemicals.

Abstract
Recent studies have indicated that long noncoding RNAs (lncRNAs) play a pivotal role in almost all physiological cellular processes, including every stage of cancer development. Given that hypoxia in the tumor microenvironment is involved in the malignant behavior of tumors, such as invasion and metastasis, we investigated the cytoplasmic and nuclear localization of lncRNAs in colorectal cancer cells. A cell culture under hypoxic conditions revealed several lncRNAs, such as LINC00152, whose levels were increased in the cytoplasm of colorectal cancer cells. A database study indicated that LINC00152 shares microRNA-binding sites, such as miR-138 and miR-193, with the hypoxia-inducible factor 1 (HIF1), thus suggesting that LINC00152 could possibly function as a competing endogenous RNA that can augment Hif1 translation in the cytoplasm of hypoxic colorectal cancer cells. Moreover, the data presented in the studies of surgically resected samples showed that patients with colorectal cancer exhibiting high LINC00152 expression were associated with a worsened survival rate; this supports the suggested oncogenic function of LINC00152 in the cytoplasm under hypoxic conditions. The present study demonstrated that lncRNA networks could provide diagnostic tools and novel therapeutic targets against colorectal cancer cells.

Wei AW, Li LF. Long non-coding RNA SOX21-AS1 sponges miR-145 to promote the tumorigenesis of colorectal cancer by targeting MYO6. Biomed Pharmacother 2017; 96:953-959. [PMID: 29217166 DOI: 10.1016/j.biopha.2017.11.145] [Citation(s) in RCA: 44] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2017] [Revised: 11/27/2017] [Accepted: 11/28/2017] [Indexed: 01/03/2023] Open
Abstract
Emerging evidences have proved that long non-coding RNAs (lncRNAs) act as important molecular regulator in the tumor progression, including colorectal cancer (CRC). LncRNA SOX21-AS1 has been verified as oncogenic molecular in other cancers and tumorigenesis. In present study, our team investigates the clinical characteristic and molecular function in CRC carcinogenesis. Results showed that lncRNA SOX21-AS1 expression was significantly over-expressed in CRC tissue samples and cells. The aberrant over-expression of SOX21-AS1 indicated poor prognosis of CRC patients. In vitro and in vivo validation experiments, SOX21-AS1 silencing inhibited the proliferation, invasion, and decreased the tumor growth of CRC cells. Moreover, miR-145 was proved to be the target of SOX21-AS1, besides, myosin VI (MYO6) was found to be one of the targets of miR-145 using bioinformatics prediction programs and rescue confirmation experiments. In summary, our study reveals the tumorigenic effect of lncRNA SOX21-AS1 in CRC cells via targeting miR-145/MYO6, providing a novel insight for CRC carcinogenesis.
