Abstract
BACKGROUND Long non-coding RNAs (lncRNAs) play a critical role in the development of ovarian cancer (OC). OBJECTIVE The study aimed to determine the role of LncRNA LINC01123 in OC bio-progression, which is upregulated in OC tissues during OC progression. METHODS Bioinformatics methods, GEPIA, and qRT-PCR were used to reveal the level and correlation of LINC01123, hsa-miR-516b-5p, and VEGFA, in OC cell lines. MTT, EdU, TUNEL, and Transwell assays were performed to assess the bioactivity of OC cell. Target sites of LINC01123 and hsa-miR-516b-5p were predicted using Starbase, and the potential linkage points of VEGFA and hsa-miR-516b-5p were predicted using TargetScan. These sites and linkage points were confirmed by double luciferase reporter assay. RESULTS LINC01123 was upregulated in OC cell lines and LINC01123 silencing suppressed the proliferation and metastasis of OC cells, but promoted cell apoptosis. hsa-miR-516b-5p was linked to LINC01123 and. VEGFA was downstream of hsa-miR-516b-5p. Importantly, silencing of hsa-miR-516b-5p reversed the inhibitory impact of si-LINC01123. The result of hsa-miR-516b-5p inhibitor + si-LINC01123 co-transfection were rescued by si-VEGFA. CONCLUSION LINC01123 promotes OC development by dampening miR-516b-5p function, and may be a novel target for treating OC.

Abstract
BACKGROUND Lung adenocarcinoma remains one of the most significant threats to human life as it involves multiple etiologies, including alteration of oncogenes or tumor-inhibitory genes. Long non-coding RNAs (lncRNAs) have been reported to have both cancer promoting and cancer inhibiting effects. In this work, we investigated the function and mechanism of lncRNA LINC01123 in lung adenocarcinoma. METHODS The expression of LINC01123, miR-4766-5p, and PYCR1 (pyrroline-5-carboxylate reductase 1) mRNA was analyzed by RT-qPCR. The protein expression levels of PYCR1 and the apoptosis-related proteins (Bax and Bcl-2) were determined by western blotting. Cell proliferation and migration were determined by CCK-8 and wound-healing assays, respectively. Tumor growth in nude mice and Ki67 immunohistochemical staining were used to determine the in vivo role of LINC01123. The putative binding relationships miR-4766-5p has with LINC01123 and PYCR1, which had been identified by analysis of public databases, were validated through RIP and dual-luciferase reporter assays. RESULTS LINC01123 and PYCR1 overexpression and miR-4766-5p downregulation were shown to occur in lung adenocarcinoma samples. LINC01123 depletion repressed lung adenocarcinoma cell growth and migration and blocked the development of solid tumors in an animal model. Moreover, LINC01123 bound directly to miR-4766-5p, the downregulation of which attenuated the anticancer effects of LINC01123 depletion in lung adenocarcinoma cells. MiR-4766-5p directly targeted downstream PYCR1 to suppress PYCR1 expression. The repressive effects of PYCR1 knockdown on the migration and proliferation of lung adenocarcinoma cells were also partly abolished by miR-4766-5p downregulation. CONCLUSION Downregulation of LINC01123 represses lung adenocarcinoma progression. This suggests that LINC01123 functions as an oncogenic driver in lung adenocarcinoma by controlling the miR-4766-5p/PYCR1 axis.

Abstract
Colorectal cancer (CRC) at an advanced stage of cancer has a lower 5-year survival rate. Research on the molecular biological mechanisms of CRC is helpful for disease prevention and treatment. Long non-coding RNAs (lncRNAs) were shown to be suitable as therapeutic targets for CRC. Previously, our research team found that LINC01123 promoted proliferation and metastasis in CRC by regulating miR-625-5p and the LIM and SH3 protein 1 (LASP1). Therefore, this study speculated that the molecular sponge effect of LINC01123 on miR-625-5p affected the process of CRC via regulating LASP1. The LINC01123-silenced CRC cell models (using the LOVO and SW480 cells) and xenograft tumor models were established to verify the above conjecture. As a result, it was found that silencing LINC01123 inhibited viability, proliferation, metastasis, and invasion but promoted apoptosis in LOVO and SW480 cells. Additionally, the knockdown of LINC01123 inhibited the LASP1, N-cadherin, PCNA, and Bcl-2 protein levels and raised the E-cadherin, Bax, and Caspase-3 protein levels in vitro. Furthermore, it showed that LINC01123, as a molecular sponge, targeted the miR-625-5p/LASP1 axis. The results of the xenograft tumor assay further verified the above effects of LINCO1123-silenced on tumor growth in vivo. And the miR-625-5p mimics treatment promoted the aforementioned effects of silencing LINC01123 on CRC cells while overexpressing LASP1 has an antagonistic effect to silencing LINC01123. In conclusion, this study suggests that silencing LINC01123 inhibits the process of CRC via sponging to the miR-625-5p/LASP1 axis. This finding hopes to provide research fundamentals on the biological mechanism study of CRC.

Abstract
The vast majority of human transcriptome is represented by various types of small RNAs with little or no protein-coding capability referred to as non-coding RNAs (ncRNAs). Functional ncRNAs include microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs), which are expressed at very low, but stable and reproducible levels in a variety of cell types. ncRNAs regulate gene expression due to miRNA capability of complementary base pairing with mRNAs, whereas lncRNAs and circRNAs can sponge miRNAs off their target mRNAs to act as competitive endogenous RNAs (ceRNAs). Each miRNA can target multiple mRNAs and a single mRNA can interact with several miRNAs, thereby creating miRNA-mRNA, lncRNA-miRNA-mRNA, and circRNA-miRNA-mRNA regulatory networks. Over the past few years, a variety of differentially expressed miRNAs, lncRNAs, and circRNAs (DEMs, DELs, and DECs, respectively) have been linked to cancer pathogenesis. They can exert both oncogenic and tumor suppressor roles. In this review, we discuss the recent advancements in uncovering the roles of DEMs, DELs, and DECs and their networks in aberrant cell signaling, cell cycle, transcription, angiogenesis, and apoptosis, as well as tumor microenvironment remodeling and metabolic reprogramming during hepatocarcinogenesis. We highlight the potential and challenges in the use of differentially expressed ncRNAs as biomarkers for liver cancer diagnosis and prognosis.

Abstract
Venous thromboembolism (VTE), a common condition in Western countries, is a cardiovascular disorder that arises due to haemostatic irregularities, which lead to thrombus generation inside veins. Even with successful treatment, the resulting disease spectrum of complications considerably affects the patient's quality of life, potentially leading to death. Cumulative data indicate that long non-coding RNAs (lncRNAs) may have a role in VTE pathogenesis. However, the clinical usefulness of these RNAs as biomarkers and potential therapeutic targets for VTE management is yet unclear. Thus, this article reviewed the emerging evidence on lncRNAs associated with VTE and with the activity of the coagulation system, which has a central role in disease pathogenesis. Until now, ten lncRNAs have been implicated in VTE pathogenesis, among which MALAT1 is the one with more evidence. Meanwhile, five lncRNAs have been reported to affect the expression of TFPI2, an important anticoagulant protein, but none with a described role in VTE development. More investigation in this field is needed as lncRNAs may help dissect VTE pathways, aiding in disease prediction, prevention and treatment.

Abstract
BACKGROUND Esophageal squamous cell carcinoma (ESCC) is one of the most lethal malignancies worldwide. Increasing evidence suggests that human papillomavirus (HPV) infection may be associated with the etiology of ESCC. However, the precise role of HPV in ESCC remains unclear. METHODS AND RESULTS Proliferation and apoptosis of ESCC cells upon infection with HPV16 E6 were detected using CCK-8 assays and Western blot analyses. The migration rate was measured with a wound healing assay, and a Transwell Matrigel invasion assay was used to detect the invasive ability. RT-qPCR was performed to detect the expression of E6AP, p53, and miR-34a. The proliferation rates were significantly higher in HPV16E6-transfected cell groups compared with the negative control groups. Bax protein expression was downregulated in HPV16E6-treated groups compared to the controls. The wound healing and Transwell Matrigel invasion assays indicated that HPV16 E6 infection could increase ESCC cell migration and invasion. Furthermore, E6AP, p53 and miR-34a expression were decreased in HPV16 E6-transfected cell lines. CONCLUSION Our results not only provide evidence that HPV16 E6 promotes cell proliferation, migration, and invasion in ESCC, but also suggests a correlation between HPV infection and E6AP, p53 and miR-34a expression. Consequently, HPV16 E6 may play an important role in ESCC development.

Abstract
Tuftelin (TUFT1) is highly expressed in various tumor types and promotes tumor growth and metastasis by activating AKT and other core signaling pathways. However, the effects of post-translational modifications of TUFT1 on its oncogenic function remain unexplored. In this study, we found that TUFT1 was SUMOylated at K79. SUMOylation deficiency significantly impaired the ability of TUFT1 to promote the proliferation, migration, and invasion of gastric cancer (GC) cells by blocking AKT/mTOR signaling pathway activation. SUMOylation of TUFT1 is mediated by the E3 SUMO ligase tripartite motif-containing protein 27 (TRIM27), and these two proteins regulate the malignant behavior of GC cells and AKT activation in the same pathway. TUFT1 binds to TRIM27 through its N-terminus, and decreased binding affinity of TUFT1 to TRIM27 significantly impairs its oncogenic effect. In addition, data collected from GC clinical samples indicated that the combined detection of TUFT1 and TRIM27 expression reflected tumor malignancy and patient survival with higher precision. In addition, we proved that SUMOylated TUFT1 is not only an upstream signal for AKT activation but also directly activates mTOR by forming a complex with Rab GTPase activating protein 1, which further inhibits Rab GTPases and promotes the perinuclear accumulation of mTORC1. Altogether, these data indicate that SUMOylated TUFT1 is the active form that affects GC progression through the AKT/mTOR signaling pathway and might be a promising therapeutic target or biomarker for GC progression.

Abstract
Flavonoids are known for potent antioxidant activity and antihyperlipidemia. As a result of the few antinutritional factors and high bioactive substances, such as flavonoids, sprouts of tartary buckwheat (Fagopyrum tataricum, STB) have become healthy food. This study aims to unravel the antihyperlipidemic effects of STB in vivo and its potential mechanism through transcriptomic and metabonomic analysis. The physiological parameters of mice administered the high-fat diet with or without 2.5 and 5% of STB for 10 weeks were recorded. Liquid chromatography-tandem mass spectrometry and RNA sequencing were applied to obtain the serum lipid metabolomic and hepatic transcriptomic profiling, respectively. Results revealed that STB could significantly alleviate the increase of body weight, liver, and abdominal adipose while ameliorating the lipid content in serum and insulin resistance of mice fed with a high-fat diet. Notably, the metabonomic analysis identified the core differential metabolites mainly enriched in the pathways, such as fat digestion and absorption, insulin resistance, and other processes. Transcriptomic results revealed that STB significantly altered the expression levels of PIK3R1, LRP5, SLC10A2, and FBXO21. These genes are involved in the PI3K-AKT signaling pathway, digestion and absorption of carbohydrates, and type II diabetes mellitus pathways. In this study, STB exhibited remarkable influence on the metabolism of lipids and glucose, exerting antihyperlipidemic effects. STB have the potential for the development and application of a lipid-lowering health food.

[PMID: 36098205 PMCID: PMC9575106 DOI: 10.1111/jcmm.17558] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2022] [Revised: 08/22/2022] [Accepted: 09/02/2022] [Indexed: 11/29/2022] Open
Abstract
Long noncoding RNAs (lncRNAs) are confirmed as the key regulators of hepatocellular carcinoma (HCC) occurrence and progression, but the role of AlkB homologue 3 antisense RNA 1 (ALKBH3-AS1) in HCC is unclear. We revealed the overexpression of ALKBH3-AS1 in HCC tissues. The upregulated levels of ALKBH3-AS1 were observed in HCC cells. ALKBH3-AS1 was expressed in the nucleus and cytoplasm of HCC cells. The high ALKBH3-AS1 expression was markedly associated with a decreased survival rate of HCC patients. ALKBH3-AS1 knockdown repressed and ALKBH3-AS1 overexpression enhanced HCC cell invasion and proliferation. ALKBH3-AS1 silencing restricted HCC growth in vivo. A significant positive correlation between ALKBH3-AS1 and ALKBH3 mRNA levels was confirmed in HCC specimens. ALKBH3-AS1 silencing reduced ALKBH3 expression by stabilizing its mRNA stability in HCC cells. Notably, the impact of ALKBH3 silencing on HCC cells was similar to that of ALKBH3-AS1 knockdown. ALKBH3 restoration prominently attenuated the suppressive effects resulting from ALKBH3-AS1 silencing in HCCLM3 cells. Hypoxia-inducible factor-1α (HIF-1α) transcriptionally activated ALKBH3-AS1 expression in hypoxic HCC cells. ALKBH3-AS1 knockdown markedly attenuated cell proliferation and invasion in hypoxic Huh7 cells. Collectively, HIF-1α-activated ALKBH3-AS1 exerted an oncogenic role by enhancing ALKBH3 mRNA stability in HCC cells.

Abstract
Among gynecological tumors, cervical cancer (CC) has the second-highest prevalence and mortality rate. α-Pinene is a bicyclic monoterpenoid compound extracted from pine needles that carried promising anticancer properties. Nevertheless, its effect on CC and the underlying mechanism has not yet been elucidated. Therefore, we investigated the effect of α-Pinene on apoptosis in CC via in vitro assays of flow cytometry (FCW), terminal deoxynucleotidyl transferase-mediated nick end labeling (TUNEL) assay, quantitative real-time polymerase chain reaction (qRT-PCR), and Western blot. Following that, we detected the proapoptotic function of α-Pinene on HeLa cells in vivo by TUNEL assay and immunofluorescence staining. Our results displayed that the α-Pinene inhibited the growth of HeLa cells and stalled the cells in the G0/G1 phase. Interestingly, we also detected that α-Pinene induced HeLa cells to apoptosis. The results investigated that α-Pinene induced HeLa cells apoptosis along with up-regulating the expression of Bax, Bid, caspase-9, caspase-3, miR-34a-5p, and down-regulating the expression of Bcl-2 in vitro. At the same time, the expression levels of target genes in vivo were consistent with those in vitro. Our experiment proved that α-Pinene promoted apoptosis, which will be used to hopefully maximize the therapeutic strategies in clinical studies in CC.

[PMID: 35836576 PMCID: PMC9273781 DOI: 10.3389/fgene.2022.900380] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2022] [Accepted: 06/13/2022] [Indexed: 02/05/2023] Open
Abstract
Background: This study aimed to screen potential drugs targeting a new prognostic gene signature associated with proliferation in hepatocellular carcinoma (HCC). Methods: CRISPR Library and TCGA datasets were used to explore differentially expressed genes (DEGs) related to the proliferation of HCC cells. Differential gene expression analysis, univariate COX regression analysis, random forest algorithm and multiple combinatorial screening were used to construct a prognostic gene signature. Then the predictive power of the gene signature was validated in the TCGA and ICGC datasets. Furthermore, potential drugs targeting this gene signature were screened. Results: A total of 640 DEGs related to HCC proliferation were identified. Using univariate Cox analysis and random forest algorithm, 10 hub genes were screened. Subsequently, using multiplex combinatorial screening, five hub genes (FARSB, NOP58, CCT4, DHX37 and YARS) were identified. Taking the median risk score as a cutoff value, HCC patients were divided into high- and low-risk groups. Kaplan-Meier analysis performed in the training set showed that the overall survival of the high-risk group was worse than that of the low-risk group (p < 0.001). The ROC curve showed a good predictive efficiency of the risk score (AUC > 0.699). The risk score was related to gene mutation, cancer cell stemness and immune function changes. Prediction of immunotherapy suggetsted the IC50s of immune checkpoint inhibitors including A-443654, ABT-888, AG-014699, ATRA, AUY-922, and AZ-628 in the high-risk group were lower than those in the low-risk group, while the IC50s of AMG-706, A-770041, AICAR, AKT inhibitor VIII, Axitinib, and AZD-0530 in the high-risk group were higher than those in the low-risk group. Drug sensitivity analysis indicated that FARSB was positively correlated with Hydroxyurea, Vorinostat, Nelarabine, and Lomustine, while negatively correlated with JNJ-42756493. DHX37 was positively correlated with Raltitrexed, Cytarabine, Cisplatin, Tiotepa, and Triethylene Melamine. YARS was positively correlated with Axitinib, Fluphenazine and Megestrol acetate. NOP58 was positively correlated with Vorinostat and 6-thioguanine. CCT4 was positively correlated with Nerabine. Conclusion: The five-gene signature associated with proliferation can be used for survival prediction and risk stratification for HCC patients. Potential drugs targeting this gene signature deserve further attention in the treatment of HCC.

Abstract
Lower extremity deep vein thrombosis (LEDVT) is a disorder of venous return caused by abnormal blood clotting. LEDVT can obstruct the lumen and is the third most common vascular disease after cerebrovascular disease and coronary artery disease. LncRNAs are associated with thrombosis and potentially affect the pathogenesis of DVT. However, no studies have reported the effect of LINC01123 on LEDVT. The aim of this study was to investigate the effect of LINC01123 on LEDVT in rats via the miR-125a-3p/interleukin 1 receptor type 1 (IL1R1) axis. Lentiviral vectors that altering LINC01123, miR-125a-3p and IL1R1 expression were pre-injected into the tail vein of rats, and an LEDVT model was established 1 day later. Detection of LINC01123, miR-125a-3p and IL1R1 expression was performed. Inflammatory factors in femoral venous blood, the length and weight of the thrombus, the histomorphological changes were determined in the rat model. The targeting relation of miR-125a-3p with LINC01123 or IL1R1 was verified. The results presented that LEDVT rats expressed high LINC01123 and IL1R1 and low miR-125a-3p expression levels. After silencing LINC01123 or elevating miR-125a-3p, the rate of thrombosis, length and weight of thrombus, and levels of inflammatory factors were reduced. The targeting relation was presented between miR-125a-3p with LINC01123 or IL1R1. Elevating IL1R1 was available to turn around the action of silence of LINC01123 on LEDVT rats. All in all, suppression of LINC01123 restrains LEDVT via miR-125a-3p to target IL1R1.

LINC01123 promotes immune escape by sponging miR-214-3p to regulate B7-H3 in head and neck squamous-cell carcinoma. Cell Death Dis 2022; 13:109. [PMID: 35115487 PMCID: PMC8814033 DOI: 10.1038/s41419-022-04542-0] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2021] [Revised: 12/30/2021] [Accepted: 01/14/2022] [Indexed: 12/24/2022]
Abstract
Numerous studies have shown that long noncoding RNAs (LncRNAs) are involved in the development and immune escape of head and neck squamous-cell carcinoma (HNSCC). However, the specific regulatory mechanisms by which LINC01123 regulates HNSCC and its correlation with immunity remain unclear. Therefore, this study’s primary purpose was to explore the mechanisms by which LINC01123 regulates the immune escape and progression of HNSCC. This study confirmed that LINC01123 is competitively bound to miR-214-3p, and miR-214-3p specifically targets B7–H3. The effects of LINC01123, B7–H3, and miR-214-3p on tumor progression, CD8+T-cell-mediated immune response, and the tumorigenicity of HNSCC in vitro and in vivo were examined through the downregulation or upregulation of LINC01123, B7–H3, and miR-214-3p. Our results indicated that LINC01123 and B7–H3 were highly expressed in HNSCC and are associated with poor prognosis in patients. Notably, overexpression of LINC01123 or B7–H3 or downregulation of miR-214-3p inhibited the function of CD8+T cells and promoted the progression of HNSCC. Therefore, LINC01123 acts as a miR-214-3p sponge to inhibit the activation of CD8+T cells and promote the progression of HNSCC by upregulating B7–H3.

Abstract
Long non-coding RNAs (lncRNAs) are critical drivers and suppressors of human hepatocellular carcinoma (HCC). The downregulation of transmembrane protein 220 antisense RNA 1 (TMEM220-AS1) is correlated with poor prognosis in HCC. Nevertheless, the role of TMEM220-AS1 in HCC and the underlying mechanism remains unclear. In this study, TMEM220-AS1 levels were markedly reduced in HCC tissues compared with noncancerous tissues. TMEM220-AS1 downregulation was confirmed in HCC cell lines. TMEM220-AS1 expression was associated with tumor stage, venous infiltration, tumor size, and survival of HCC patients. TMEM220-AS1 overexpression suppressed the migration, invasion, and proliferation of HCC cells. Interestingly, ectopic expression of TMEM220-AS1 increased TMEM220 levels in HCC cells. Decreased TMEM220 levels were observed in HCC tissues and cell lines. TMEM220 expression was positively correlated with TMEM220-AS1 levels in HCC tissue samples and TMEM220 downregulation was significantly correlated with reduced patient survival. TMEM220 overexpression suppressed HCC cell proliferation and mobility. TMEM220 knockdown eliminated the suppressive effect of TMEM220-AS1 in HCCLM3 cells. Mechanistically, TMEM220 overexpression reduced the nuclear accumulation of β-catenin and decreased MYC, Cyclin D1, and Snail1 mRNA levels in HCCLM3 cells. BIO, a GSK3β inhibitor, eliminated TMEM220-induced Wnt/β-catenin pathway inactivation and inhibited HCC cell proliferation and mobility. In conclusion, TMEM220-AS1 and TMEM220 were expressed at low levels in HCC patients. TMEM220-AS1 inhibited the malignant behavior of HCC cells by enhancing TMEM220 expression and subsequently inactivating the Wnt/β-catenin pathway.

Abstract
The main cause of steroid-induced necrosis of femoral head (SNFH) is excessive glucocorticoid (GC) intake. The aim of this article was to investigate the role of lncRNA NEAT1 as a molecular sponge to adsorb miR-23b-3p and regulate CYP1A2 in SNFH. Fluorescence in situ hybridization was used to localize lncRNA NEAT1. Human bone marrow mesenchymal stem cells (hBMSCs) were collected from patients with SNFH. The expression of lncRNA NEAT1, miR-23b-3p and CYP1A2 in hBMSCs were intervened. Compared to the control group, the lncRNA NEAT1 and CYP1A2 expression in the SNFH group was increased, while miR-23b-3p expression was decreased. GCs could inhibit the osteogenic differentiation of hBMSCs and upregulate the expression of lncRNA NEAT1. Knockdown of lncRNA NEAT1 could promote the proliferation and osteogenic differentiation of hBMSCs in the SNFH group. Overexpression of miR-23b-3p could partially counteract the effect of lncRNA NEAT1 on hBMSCs. CYP1A2 was confirmed to be a target of miR-23b-3p. Overexpression of CYP1A2 could partially rescue the effect of miR-23b-3p overexpression on hBMSCs. In conclusion, lncRNA NEAT1 as a ceRNA can adsorb miR-23b-3p and promote the expression of CYP1A2, which then inhibits the osteogenic differentiation of hBMSCs and promotes the progress of SNFH.

Abstract
Purpose Hepatocellular carcinoma (HCC), a malignant tumor that exists worldwide, has a high morbidity and mortality rate. Previous studies have reported that lncRNA NR2F1-AS1 plays a critical role in several cancers. Here, we aimed to investigate the biological function of NR2F1-AS1 and its molecular mechanism in the migration and invasion of HCC. Methods Quantitative real-time PCR (qRT-PCR) was performed to analyze NR2F1-AS1 expression in HCC. The biological function was investigated by transwell invasion and migration assays. The protein level was identified by Western blot. In addition, the downstream targets of NR2F1-AS1 and miR-642a were confirmed by luciferase reporter assays. Results NR2F1-AS1 was significantly upregulated in HCC and associated with the poor prognosis of HCC patients. Biological function experiments revealed that the silence of NR2F1-AS1 suppressed cell invasion and migration in HCC. More importantly, NR2F1-AS1 directly interacted with miR-642a and negatively regulated miR-642a. DEK was the target of miR-642a, and NR2F1-AS1 positively regulated DEK expression by suppressing miR-642a. Conclusion Taken together, it is the first time we discovered the interaction of NR2F1-AS1 with miR-642a in modulating HCC cell invasion and migration.

Abstract
Radiotherapy represents the most effective nonsurgical therapy, whereas acquired radioresistance remains a major challenge in glioma treatment. Deregulation of long noncoding RNAs (lncRNAs) is frequently involved in tumorigenesis. This study investigates the role of LINC01123 in radioresistance in glioma with molecules involved. LINC01123 was identified as the most upregulated gene in a glioma gene expression dataset GSE103227. LINC01123 was highly expressed in the radioresistant glioma tissues radioresistant glioma U251 (U251R) cells. Downregulation of LINC01123 reduced cell proliferation and colony formation abilities, as well as resistance to apoptosis of the U251R cells after 4 Gy X-ray irradiation. The micro(mi)RNA-151a gene (miR-151a) was a poorly expressed miRNA in glioma, and it was a target of LINC01123. The centromere protein B gene (CENPB) mRNA was a direct target of miR-151a and demonstrated a positive correlation with LINC01123 in glioma tissues and cells. Further inhibition of miR-151a or overexpression of CENPB restored radioresistance of glioma cells. In addition, silencing of LINC01123 suppressed growth of xenograft tumors formed by U251R cells in nude mice. To conclude, the present study demonstrates that LINC01123 serves as a sponge for miR-151a and upregulates CENPB expression to increase the radioresistance of glioma cells in vitro and in vivo.

Abstract
OBJECTIVE Oral squamous cell carcinoma (OSCC) is a malignant tumor. This study aimed to investigate the role of a long noncoding RNA (lncRNA), LINC01123, in OSCC prognosis and progression and to explore the underlying mechanisms. STUDY DESIGN OSCC tissues were collected from 102 patients, and 4 OSCC cell lines were analyzed. The expression levels of LINC01123 and miR-34a-5p were estimated using quantitative real-time polymerase chain reaction (qRT-PCR). Cell counting kit-8 (CCK-8) and Transwell assays were used to assess the proliferation, migration, and invasion of OSCC cells. Kaplan-Meier survival analysis was used to analyze the prognostic value of LINC01123 in OSCC. RESULTS The analysis results showed that LINC01123 was overexpressed in OSCC tumor tissues; also, the prognosis of patients with OSCC with high LINC01123 expression levels was poor. The knockdown of LINC01123 inhibited the proliferation, migration, and invasion of OCSS cells. MiR-34a-5p was a target of LINC01123, and its inhibitor could reverse the effect of silenced LINC01123 on the progression of OSCC. CONCLUSIONS Highly expressed LINC01123 was associated with poor prognosis of OSCC and regulated OSCC cell proliferation, invasion, and migration by sponging miR-34a-5p. Therefore, the LINC01123/miR-34a-5p axis may provide new ideas for the prognosis and treatment of OSCC.

J Cancer 2021; 12:4099-4108. [PMID: 34093813 PMCID: PMC8176253 DOI: 10.7150/jca.58097] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2021] [Accepted: 04/27/2021] [Indexed: 12/15/2022] Open
Abstract
Recent reports show that long noncoding RNA (lncRNA) FIRRE contributes to the proliferation, apoptosis resistance, and invasion of colorectal cancer and diffuse large B-cell lymphoma. However, the biological function of FIRRE in hepatocellular carcinoma (HCC) remains unknown. Here, we disclosed that the FIRRE level was frequently increased in HCC compared to nontumor tissues. Compared with normal liver cells, we also confirmed the upregulated level of FIRRE in HCC cells. Notably, the FIRRE high expression was related to malignant clinical features, including advanced TNM stage and tumor size ≥5 cm, and conferred to worse survival of HCC. Functionally, FIRRE knockdown repressed the proliferation and glycolysis of HCCLM3 cells. Overexpression of FIRRE strengthened Huh7 cell proliferation and glycolysis. Notably, FIRRE positively regulated the glycolic enzyme 6-phosphofructo-2-kinase/fructose-2,6-biphosphatase 4 (PFKFB4) expression in HCC cells. PFKFB4 was highly expressed and positively associated with FIRRE level in HCC tissues. The upregulated expression of PFKFB4 was associated with high tumor grade and advanced TNM stage. TCGA data revealed that the PFKFB4 high expression indicated a poor prognosis of HCC. Mechanistically, modulating FIRRE level did not affect the stability of PFKFB4 mRNA. FIRRE was mainly distributed in HCC cells' nucleus and promoted PFKFB4 transcription and expression via cAMP-responsive element-binding protein (CREB). PFKFB4 could abolish the effects of FIRRE knockdown on HCC cell proliferation and glycolysis. To conclude, the highly expressed FIRRE facilitated HCC cell proliferation and glycolysis by enhancing CREB-mediated PFKFB4 transcription and expression.

TUFT1 Facilitates Metastasis, Stemness, and Vincristine Resistance in Colorectal Cancer via Activation of PI3K/AKT Pathway. Biochem Genet 2021; 59:1018-1032. [PMID: 33634374 DOI: 10.1007/s10528-021-10051-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2020] [Accepted: 02/10/2021] [Indexed: 12/22/2022]
Abstract
Since the incidence and mortality of colorectal cancer (CRC) are increasing in recent years, the research on the pathogenesis of colorectal cancer has attracted more and more attention. Here, our results confirmed that the mRNA expression level and proteins accumulation of TUFT1 were significantly increased in CRC tissues from late-stage CRC patients (III + IV) (p < 0.001), indicated by qPCR and IHC assay. The TUFT1 expression was positively correlated with tumor stage by analyzing 126 specimens from CRC patients. Next, we found that up-regulation of TUFT1 enhanced the migration and invasion of LoVo cells, whereas the down-regulation of TUFT1 observably weakened the migration and invasion of SW837 cells, indicating that TUFT1 promotes the metastasis of CRC cells. In addition, TUFT1 overexpression increased the number of mammary spheres and vincristine resistance of LoVo cells by sphere formation assay and measuring the IC50 value, suggesting the TUFT1 promotes stemness and the vincristine resistance of CRC cells. Finally, we found that TUFT1 overexpression increased p-AKT in LoVo cells, while down-regulation of TUFT1 decreased the p-AKT levels in SW837 cells. Therefore, we determined that the function of TUFT1 in CRC depends on PI3K/AKT pathway. Taken together, these data demonstrated that TUFI1 facilitates metastasis, stemness, and vincristine resistance of colorectal cancer cells via activation of PI3K/AKT pathway, which might act as a promising therapeutic target for CRC.
