Abstract
Glioma remains the most frequent malignancy of the central nervous system. Recently, necroptosis has been identified as a cell death process that mediates the proliferation and development of tumor cells. LncRNAs play a key role in the diagnosis and treatment of various diseases. However, the impact that necrosis-related lncRNAs (NRLs) have on glioma remains unclear. In our studies, we selected 9 NRLs to construct a prognostic model. Meanwhile, we assessed the survival curves of these 9 NRLs. Our findings found ADGRA1-AS1 and WAC-AS1 were protective lncRNAs, while MIR210HG, LINC01503, CRNDE, HOXC-AS1, ZIM2-AS1, MIR22HG and PLBD1-AS1 were risk lncRNAs. Specifically, 12 immune cells, 25 immune-correlated pathways, and TME score were differentially expressed in the both risk groups. Additionally, the study predicted and validated the necroptosis-related lncRNA CRNDE/miR-23b-3p/IDH1 axis. CRNDE was strongly expressed in glioma specimens and several cell lines. Inhibiting CRNDE resulted in a substantial reduction in the proliferation and migration of U-118MG and U251 cells. Furthermore, the study predicted that CRNDE may exhibit oncogenic features by adsorbing miR-23b-3p and positively regulating IDH1 expression. Overall, the study constructed a prognostic model in glioma, and predicted a lncRNA CRNDE/miR-23b-3p/IDH1 axis, which could potentially be useful for gene therapy of glioma.

Abstract
OBJECTIVE To investigate the clinical and prognostic significance of long non-coding RNA (lncRNA) CRNDE expression in severe pneumonia and its correlation with the levels of inflammatory factors. METHODS In this retrospective study, 86 patients with severe pneumonia were selected as the observation group (OG), and 70 patients with non-severe pneumonia were selected as the control group (CG). The expression of lncRNA CRNDE was measured by real-time fluorescence quantitative reverse transcription polymerase chain reaction. The relationship between lncRNA CRNDE expression and clinical characteristics and prognosis of patients was analyzed. The correlation between lncRNA CRNDE expression and the levels of inflammatory factors related to severe pneumonia was also analyzed. RESULTS Relative expression of lncRNA CRNDE in OG was significantly higher than that in CG (P<0.05). The receiver operator characteristic (ROC) curve analysis revealed that lncRNA CRNDE expression could be used for the detection of severe pneumonia. The expression of lncRNA CRNDE was not related to gender, age, or smoking history (all P>0.05), but related to the pneumonia severity index (PSI) score, Acute Physiology and Chronic Health Evaluation (APACHE) II score, and procalcitonin (PCT), C-reactive protein (CRP), and D-dimer (DD) expression (P<0.05). Spearman correlation analysis revealed that lncRNA CRNDE expression was positively correlated with the expressions of PCT, CRP, and DD (r=0.908, 0.898, and 0.951, respectively, P<0.001). CONCLUSIONS lncRNA CRNDE is highly expressed in the serum of patients with severe pneumonia and is an independent risk factor for the poor prognosis of these patients. The expression of lncRNA CRNDE is also positively correlated with the levels of inflammatory factors in such patients, which can be used for the clinical detection of severe pneumonia.

Abstract
Background The long-noncoding RNA colorectal neoplasia differentially expressed (CRNDE) gene has been found to be upregulated in several solid tumors. Whether CRNDE affects osteosarcoma (OS) and its underling mechanism remains unknown. Methods Tumor tissues and corresponding normal tissues were collected from 45 patients with OS. Quantitative reverse transcription polymerase chain reaction (qRT-PCR) was applied to determine lncRNA CRNDE level in the tissues. Participants were divided into a high CRNDE group and a low CRNDE group according to the median value of lncRNA CRNDE expression detected by in situ hybridization (ISH). The differences between high and low expression of lncRNA CRNDE in patients were compared clinically by chi-square test. Kaplan-Meier survival analysis was applied to analyze the relationship between lncRNA CRNDE expression and patient survival. Subsequently, silencing or overexpression of lncRNA CRNDE were performed in MG63 and 143B cell lines, qRT-PCR was applied to verify the expression of lncRNA CRNDE, miR-136-5p, and MRP9; dual-luciferase reporter assay was used to evaluate the targeting relationship between miR-136-5p, lncRNA CRNDE, and Cell Counting Kit-8 (CCK8), wound-healing, and Transwell assays were used to analyze for cell proliferation, migration, and invasion, respectively, and western blot was used to detect expression in cells. Results The expression of CRNDE in OS tissues was higher than that in normal tissues. High lncRNA CRNDE expression was significantly associated with clinical stage, lung metastasis, and poor prognosis in OS patients. Additionally, overexpression of lncRNA CRNDE promoted proliferation and migration of OS cells. Bioinformatics analysis showed that lncRNA CRNDE competitively inhibited miR-136-5p through acting as a competitive endogenous RNA (ceRNA). It was also revealed that miR-136-5p is a binding target gene of lncRNA CRNDE and that MRP9 is involved in this process as a downstream target gene of miR-136-5p. Conclusions The lncRNA CRNDE promotes the proliferation and migration of OS cells by regulating the miR-136-5p/MRP9 pathway, and lncRNA CRNDE can be a significant marker of OS prognosis.

Abstract
Osteoarthritis (OA) is mainly characterized by articular cartilage degeneration, synovial fibrosis, and inflammation. LncRNA CRNDE (colorectal neoplasia differentially expressed) has been reported to be down-regulated in age-related OA, but its role in injury-induced OA needs to be further explored. In this study, an OA rat model was established using anterior cruciate ligament transection, and the adenovirus-mediated CRNDE overexpression (Ad-CRNDE) or DACT1 (dapper antagonist of catenin-1) interference (sh-DACT1) vectors were administered by intraarticular injection. Moreover, chondrocyte‑like ATDC5 cells were treated with IL-1β (10 ng/mL) to simulate OA conditions in vitro. We found that overexpression of CRNDE alleviated cartilage damage and synovitis in OA rats, and suppressed IL-1β-induced apoptosis, inflammation, and extracellular matrix (ECM) degradation in chondrocyte‑like ATDC5 cells, while silencing DACT1 effectively antagonized the protective effect of CRNDE both in vivo and in vitro. Mechanism studies revealed that DACT1 could act as a downstream target of CRNDE. By recruiting p300, CRNDE promoted the enrichment of H3K27ac in the DACT1 promoter, thus promoting DACT1 transcription. In addition, CRNDE hindered the activation of the Wnt/β-catenin pathway in IL-1β-stimulated cells by inducing DACT1 expression. In conclusion, CRNDE promoted DACT1 expression through epigenetic modification and restrained the activation of Wnt/β-catenin signaling to impede the progression of OA.

Abstract
BACKGROUND Activation of NLRP3 inflammasome in macrophages contributes greatly to IgA nephropathy (IgAN) progression. This study intended to investigate the underlying mechanism of NOD-like receptor family, pyrin domain containing 3 (NLRP3) inflammasome activation in the development of IgAN. METHODS We examined the expression levels of colorectal neoplasia differentially expressed (CRNDE), NLRP3 inflammasome-related proteins in peripheral blood mononuclear cells (PBMCs) and J774A.1 cells and detected inflammatory cytokine levels in the serum of IgAN patients and cell supernatants of in vitro IgAN model. RNA pull-down and RNA immunoprecipitation (RIP) experiments were conducted to evaluate the interaction between CRNDE and NLRP3. Then, the ubiquitin level of NLRP3 and its binding ability to TRIM family member 31 (TRIM31) were determined. RESULTS Compared with the control group, the expressions of CRNDE and NLRP3 inflammasome-related proteins in PBMCs and J774A.1 cells and levels of IL-1β, TNF-α and IL-12 in serum of IgAN patients and cell supernatants of IgA-IC-induced J774A.1 cells were all increased. CRNDE silencing down-regulated NLRP3 inflammasome-related proteins and the levels of IL-1β, TNF-α and IL-12 in cell supernatants, while NLRP3 overexpression reversed these effects. Additionally, CRNDE could interact with NLRP3 and promote NLRP3 expression. Furthermore, inhibition of CRNDE reduced NLRP3 protein level and promoted TRIM31-mediated NLRP3 ubiquitination and degradation. CONCLUSION CRNDE exacerbates IgA nephropathy progression through restraining ubiquitination and degradation of NLRP3 and facilitating NLRP3 inflammasome activation in macrophages.

Abstract
Due to persistent inconsistencies in the expression data of alcoholic liver disease (ALD), it is necessary to turn to “pre-laboratory” comprehensive analysis in order to accelerate effective precision medicine and transformation research. We screened pseudogene-derived lncRNA associated with ALD by comparative analysis of 2 independent data sets from GEO. Three lncRNAs (CRNDE, RBMS3-AS3, and LINC01088) were demonstrated to be potentially useful diagnostic markers in ALD. Among them, the expression of CRNDE is up-regulated. Therefore, we focus on CRNDE. Kyoto Encyclopedia of Genes and Genomes pathways analysis revealed higher CRNDE can activate MAPK signaling pathway, apoptosis, wnt signaling pathway, and hematopoietic cell lineage. Next, we established ALD animal model and verified the success of the modeling. The result showed ALD tissues in mice had significantly higher CRNDE levels than normal tissues. Moreover, the increase of IL-6 in the serum of mice in the low-dose group is related to the activation of inflammatory factors after alcohol-induced liver injury. In addition, alcohol can induce apoptosis, and knockdown of CRNDE can reduce apoptosis. Our integrated expression profiling identified CRNDE independently associated with ALD. CRNDE can facilitate inflammation and apoptosis in ALD.

Abstract
Objectives It is reported that long non‐coding RNA (lncRNA) colorectal neoplasia differentially expressed (CRNDE) targets microRNA (miR)‐33a, miR‐181a and miR‐495 to regulate inflammation process, while few studies report their clinical application for paediatric asthma management. Therefore, this study aimed to explore the interaction of lncRNA CRNDE with miR‐33a, miR‐181a and miR‐495, as well as their correlation with inflammation, exacerbation risk and severity in paediatric patients with asthma. Methods Asthmatic exacerbation children (N = 65), asthmatic controlled children (N = 65) and controls (N = 65) were recruited. LncRNA CRNDE, miR‐33a, miR‐181a and miR‐495 expressions in peripheral blood mononuclear cells were detected by RT‐qPCR. Besides, serum inflammatory cytokines (including TNF‐α, IL‐1β, IL‐6 and IL‐17) were determined by enzyme‐linked immunosorbent assay (ELISA). Results LncRNA CRNDE, miR‐33a and miR‐495 expressions were different, while miR‐181a expression was similar among asthmatic exacerbation children, asthmatic controlled children and controls. Moreover, lncRNA CRNDE negatively correlated with miR‐33a and miR‐495 in asthmatic exacerbation children and asthmatic controlled children, but not in controls. Further analyses showed that lncRNA CRNDE positively correlated with TNF‐α, IL‐1β, IL‐17 and exacerbation severity, while it negatively correlated with FEV1/FVC in asthmatic exacerbation children. Meanwhile, miR‐33a, miR‐181a and miR‐495 all negatively correlated with some individual inflammatory cytokines, while only miR‐33a negatively correlated with exacerbation severity in asthmatic exacerbation children. Conclusion LncRNA CRNDE correlates negatively with miR‐33a and miR‐495 and positively with inflammatory cytokines in asthmatic children.

Abstract
BACKGROUND Cardiomyocytes apoptosis is the basic pathological process of myocardial ischaemia/reperfusion (MI/R) injury, so inhibiting apoptosis of cardiomyocytes can effectively improve MI/R injury. Long non-coding RNA colorectal neoplasia differentially expressed (lncRNA CRNDE) can inhibit cell apoptosis, but its specific role in MI/R injury has not been studied. The aim of this study is to explore the specific effect of lncRNA CRNDE on cardiomyocytes apoptosis. METHODS MI/R model in vivo and hypoxia/re-oxygenation (H/R) model in vitro were constructed. Apoptotic levels were assessed by TUNEL staining assay. QRT-PCR was used to validate lncRNA CRNDE level in myocardial tissues and HL-1 cells. The protein expressions of YAP1, Bcl-2 and cleaved caspase-3 were detected by western blot analysis. Flow cytometry was used to determine the apoptosis rate of cardiomyocytes. RIP assay was used to detect the interaction between lncRNA CRNDE and YAP1. RESULTS The extent of cardiomyocytes apoptosis was significantly increased, and the levels of lncRNA CRNDE, YAP1 and Bcl-2 were down-regulated, while cleaved caspase-3 expression was up-regulated in MI/R mice and H/R-treated HL-1 cells. The expressions of YAP1 and Bcl-2 were decreased, while the expression of cleaved caspase-3 was increased after the knockdown of lncRNA CRNDE. Furthermore, lncRNA CRNDE could bind to YAP1 and regulated the protein level of YAP1 by ubiquitination and proteasomal degradation pathway. After transfection of Si-YAP1 in the H/R-treated HL-1 cells transfected with pc-DNA CRNDE, the protein level of Bcl-2 was decreased, while cleaved caspase-3 expression and the apoptosis rate were increased. CONCLUSION Our study suggested that lncRNA CRNDE could regulate YAP1 level by ubiquitination and proteasomal degradation pathway, thus inhibiting cardiomyocytes apoptosis in MI/R injury.

Abstract
BACKGROUND This study was performed to evaluate the diagnostic and prognostic value, as well as the role of long-chain noncoding RNA (lncRNA) colorectal neoplasia differentially expressed (CRNDE) in osteosarcoma (OS). MATERIALS AND METHODS A quantitative real-time polymerase chain reaction assay was to determine lncRNA CRNDE and microRNA-335-3p (miR-335-3p) expressions. The Kaplan-Meier analysis was to analyze the relationship between lncRNA CRNDE expression and survival in patients with OS. Receiver operating characteristic curves were to evaluate the diagnostic value of lncRNA CRNDE in OS. Bioinformatics analysis and luciferase reporter assays were used to predict and confirm the relationship between lncRNA CRNDE and miR-335-3p. Cell counting Kit-8 and transwell migration assays assessed the role of lncRNA CRNDE and miR-335-3p in OS cells. RESULTS lncRNA CRNDE expression was upregulated and miR-355-3p expression was downregulated in OS. In patients with OS, low lncRNA CRNDE expression demonstrated higher overall survival, whereas high lncRNA CRNDE expression was an independent poor prognostic factor. Furthermore, increased lncRNA CRNDE expression was associated with distant metastasis and the tumor-node-metastasis stage in patients with OS, which can be considered as an independent diagnostic biomarker in OS. We revealed that miR-335-3p was the target of lncRNA CRNDE. It also demonstrated that knockdown of lncRNA CRNDE inhibited OS cell proliferation, migration, and invasion, and inhibition of miR-355-3p promoted this effect. Finally, miR-335-3p partially mediated the stimulatory effects of lncRNA CRNDE in OS. CONCLUSION We demonstrated that lncRNA CRNDE is a potential diagnostic and prognostic biomarker for OS, and the lncRNA CRNDE/miR-335-3p axis participates in OS progression.

Abstract
Background This article focuses on the roles and mechanism of lncRNA CRNDE on the progression of HCC. Methods We used qRT-PCR to detect the expression of lncRNA CRNDE in HCC cells, normal cells and clinical tissues. MTT assay, FCM analysis, Transwell migration and invasion assay were used to detect the effects of lncRNA CRNDE on cell viability, apoptosis, migration and invasion of HCC cells. The expression of apoptosis-related proteins Bcl-2, Bax, Cleaved Caspase 3, Cleaved Caspase 9, EMT epithelial marker E-cadherin and mesothelial marker Vimentin were analyzed by Western blot. Online prediction software was used to predict the binding sites between lncRNA CRNDE and miR-539-5p, or miR-539-5p and POU2F1 3’UTR. Dual luciferase reporter assay, qRT-PCR and RNA pulldown were used to detect target-relationship between lncRNA CRNDE and miR-539-5p. Dual luciferase reporter assay, qRT-PCR, Western blot and Immunofluorescence were used to detect target-relationship between miR-539-5p and POU2F1. qRT-PCR was used to detect the expression of miR-539-5p and POU2F1 in clinical tissues. Rescue experiments was used to evaluate the association among lncRNA CRNDE, miR-539-5p and POU2F1. Finally, we used Western blot to detect the effects of lncRNA CRNDE, miR-539-5p and POU2F1 on NF-κB and AKT pathway. Results lncRNA CRNDE was highly expressed in HCC cells and HCC tissues compared with normal cells and the corresponding adjacent normal tissues. lncRNA CRNDE promoted the cell viability, migration and invasion of HCC cells, while inhibited the apoptosis and promoted the EMT process of HCC cells. lncRNA CRNDE adsorbed miR-539-5p acts as a competitive endogenous RNA to regulate POU2F1 expression indirectly. In HCC clinical tissues, miR-539-5p expression decreased and POU2F1 increased compared with the corresponding adjacent normal tissues. lncRNA CRNDE/miR-539-5p/POU2-F1 participated the NF-κB and AKT pathway in HCC.

Abstract
BACKGROUND This study aimed to test the hypothesis that long non-coding RNA (lncRNA) colorectal neoplasia differentially expressed (CRNDE) could exacerbate brain injury caused by intrauterine infection in neonatal rats. METHODS Intrauterine infection was induced in pregnant rats by lipopolysaccharide (LPS). After delivery, newborn rats with brain injury caused by intrauterine infection were randomly divided into control, control shRNA, and CRNDE shRNA groups. CRNDE expression in serum and amniotic fluid of pregnant rats and neonatal brain tissues were determined by quantitative real-time PCR (qRT-PCR). Morris water maze (MWM) task was used to test the spatial learning and memory ability. Histological examination and apoptosis detection were performed by hematoxylin and eosin (H&E) and terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining, respectively. Immunohistochemistry was conducted to evaluate the activation of astrocytes and microglia. RESULTS LncRNA CRNDE was highly expressed in serum and amniotic fluid of maternal rats and in brain tissues of offspring rats. Furthermore, shRNA-mediated CRNDE downregulation could rescue the spatial learning and memory ability, improve brain histopathological changes and cell death, and inhibit the activation of astrocytes and microglia caused by LPS. CONCLUSION CRNDE silencing possessed a cerebral protective effect in neonatal rats with brain injury caused by interauterine infection.

Abstract
Purpose Synchronous colorectal liver metastasis (SCLM) had limited availability of tools to predict survival and tumor recurrence. LncRNA CRNDE and lncRNA SNHG7 have been proven to be closely related to cancer progression. However, the predictive value of lncRNA CRNDE and lncRNA SNHG7 in cancer prognosis is still unclear. The purpose of this study was to investigate whether lncRNA CRNDE and lncRNA SNHG7 could be used as promising biomarkers for prognosis prediction of SCLM patients who underwent hepatectomy. Methods The expression profile of lncRNA CRNDE and lncRNA SNHG7 in serum of SCLM patients was examined by qRT-PCR. The relationship between lncRNA expression and clinicopathological characteristics was analyzed. The Cox proportional-hazards regression model and Kaplan-Meier analysis were performed to analyze the association between lncRNA expression and overall survival (OS) and tumor recurrence of SCLM patients. Results Levels of lncRNA CRNDE and lncRNA SNHG7 in patients who underwent recurrence or death were significantly higher than that of patients with recurrence-free or survival (P<0.01). Both lncRNA CRNDE high level and lncRNA SNHG7 high level showed a significant correlation with differentiation of primary tumor, invasion depth of primary focus, lymph node metastases, number of liver metastases, and liver metastasis grade. High levels of lncRNA CRNDE or lncRNA SNHG7 predicted shorter recurrence time, shorter OS time, higher recurrence rate and lower OS rate. Furthermore, lncRNA CRNDE and lncRNA SNHG7 were independent risk factors for high recurrence and poor OS in SCLM underwent hepatectomy. Conclusion Taken together, lncRNA CRNDE and lncRNA SNHG7 could be promising biomarkers for prediction of OS and tumor recurrence in SCLM underwent hepatectomy.

Abstract
OBJECTIVE This article aims to investigate the mechanism of microRNA-495 (miR-495) and long non-coding RNA CRNDE on the apoptosis of colonic epithelial cells in inflammatory bowel diseases (IBDs). METHODS The mouse model of IBD was induced by dextran sulfate sodium (DSS), and human colonic epithelial cell lines (HT-29, LOVO, and Caco-2) were treated with DSS, and received cell transfection. RNA interference was used to down-regulate CRNDE expression. RESULTS CRNDE and SOCS1 were highly expressed, but miR-495 was lowly expressed in the DSS-induced colitis tissues and colonic epithelial cell lines. Interference of CRNDE inhibited cell apoptosis of DSS-induced colonic epithelial cells. The interaction between CRNDE and miR-495 was confirmed by RNA immunoprecipitation and RNA pull-down assay. The target relationship between miR-495 and SOCS1 was confirmed by the luciferase reporter assay. CRNDE promoted DSS-induced colonic epithelial cell apoptosis via miR-495/SOCS1. CRNDE interference in DSS-induced colitis mouse model alleviated clinical manifestations of IBD. CONCLUSIONS Our findings demonstrated that CRNDE promoted DSS-induced colonic epithelial cell apoptosis via suppressing miR-495 and increasing SOCS1, indicating CRNDE as a novel target of treating IBD.

Abstract
Melanoma was the most malignant skin neoplasm with an increasing morbidity around the world. Although new immunotherapies and targeted therapies have emerged recently, the long-term survival of melanoma patients still remains low. To reveal effective diagnostic methods and therapeutic strategies, the potential mechanism of melanoma is urgently needed to be studied. Long non-coding RNAs (lncRNAs) have become an important regulatory factor in the occurrence and development of cancer, and it can be used as a new prognostic and diagnostic marker. In this study, we aimed to inspect the effects of lncRNA colorectal neoplasia differentially expressed (CRNDE) on the melanoma cell viability, invasion and migration. After microarray analysis, 106 dysregulated lncRNAs and 1187 abnormally expressed mRNAs were screened out. Further, the lncRNA CRNDE and CCL18 expression in melanoma tissues and cell lines were examined. It was determined that they were both overexpressed in melanoma tissues and cell lines. The down-regulation of lncRNA CRNDE and CCL18 induced melanoma cell apoptosis and inhibited cell viability. Then, miR-205 which had binding site with lncRNA CRNDE and CCL18 was involved in the next experiment, and it was down-regulated in melanoma that negatively correlated with lncRNA CRNDE expression. In addition, overexpression of miR-205 results in the restore of cell viability and aggressiveness. In conclusion, LncRNA CRNDE promotes the migration and invasion of melanoma by sponging miR-205 and releasing CCL18.

Abstract
The clinical significance and essential role of long non-coding RNA colorectal neoplasia differentially expressed (lncRNA CRNDE) have been well illuminated in various cancers. However, the function of CRNDE in intrahepatic cholangiocarcinoma (IHCC) has not been reported at present. The aim of the present study was to investigate the role of CRNDE in IHCC. Firstly, the relative expression of CRNDE was observed to be upregulated in IHCC cell lines and tissues. And high CRNDE expression was statistically associated with IHCC differentiation grade, lymph node metastasis, tumor-nodes-metastasis (TNM) stage and size. Survival analysis identified that high CRNDE expression is a predictor of worse overall survival (OS) and progression-free survival (PFS) in patients with IHCC. Moreover, high CRNDE expression was identified as an independent risk factor of IHCC poor OS and PFS. Further studies of in vitro assays suggested that CRNDE silencing could suppress the proliferation of HuCCT1 cells following CCK-8 and colony formation assays, while CRNDE ectopic expression in HCCC9810 cells promoted proliferation. Moreover, the migration and invasion of HuCCT1 cells were greatly repressed with CRNDE deficiency following Transwell and Matrigel assays. Accordingly, the motility of HCCC9810 cells was notably accelerated with CRNDE overexpression. Mechanistically, CRNDE was revealed to facilitate the epithelial-mesenchymal transition (EMT) of IHCC cells. In conclusion, these observations indicated that CRNDE could promote the clinical progression and metastasis of IHCC by facilitating EMT. CRNDE may be a novel prognostic marker and therapeutic target in IHCC.

Abstract
This study was intended to analyze effects of lncRNA CRNDE on cervical cancer cell growth and metastasis. Fifty pairs of cervical cancer tissues and corresponding adjacent tissues were collected. Expressions of long non-coding RNAs (lncRNAs) in tissue samples were detected by microarray analysis. Expression levels of CRNDE in cervical cancer cells and normal cells were detected by qRT-PCR. Cell-counting kit-8 (CCK-8) assay and clone formation assay were utilized to evaluate cell growth. Wound healing assay and Transwell assay were conducted to detect the migratory and invasive capability of cervical cancer cells. The expressions of CRNDE in cervical cancer tissues and cells were higher than those in normal tissues and cells. CCK-8 assay and clone formation assay showed that the knockdown of CRNDE could inhibit the cell proliferation of HeLa and C-33A cells. Wound healing assay indicated that the downregulation of CRNDE expression could suppress the cell migration. The result of a Transwell assay demonstrated that the number of invasion cells reduced in the CRNDE-si group in comparison with the Mock group. LncRNA CRNDE could promote the cell growth and stimulate the metastasis of cervical cancer cells.
