Abstract
LncRNA HOTAIR has been reported to be associated with metabolic diseases of the liver. However, the effect of HOTAIR on non-alcoholic fatty liver disease (NAFLD) inflammation and its potential mechanism have not been reported. Genes and proteins expression were detected by qRT-PCR and Western blot respectively. The level of inflammatory cytokines was assessed by ELISA. HepG2 cell viability was detected by MTT assay. TG level and lipid accumulation were measured by Assay Kit and Oil red O staining, respectively. Direct binding relationship between HOTAIR and Serine/arginine splicing factor 1 (SRSF1), SRSF1 and MLX interacting protein like (MLXIPL) were confirmed by RNA-pull down and RIP assay. HOTAIR was highly expressed in free fatty acids (FFA)-treated HepG2 cells. HOTAIR knockdown alleviated FFA-induced inflammation of HepG2 cells. Then further analysis showed that HOTAIR and SRSF1 had a mutual binding relationship, and HOTAIR maintained MLXIPL mRNA stability via recruiting SRSF1 in HepG2 cells. Moreover, the inhibitory effect of HOTAIR knockdown on FFA-induced inflammation in HepG2 cells was reversed by MLXIPL overexpression. HOTAIR accelerates inflammation of FFA-induced HepG2 cells by recruiting SRSF1 to stabilize MLXIPL mRNA, which will help to find new effective strategies for NAFLD therapy.

Abstract
BACKGROUND The abnormal expression of long noncoding RNA (LncRNA) HOTAIR has been associated with synovial angiogenesis in rheumatoid arthritis (RA). The aim of this study is to investigate whether LncRNA HOTAIR plays a role in synovial angiogenesis in RA by regulating the phosphoinositide 3-kinase/protein kinase B (PI3K/AKT) pathway through the miR-126-3p/PIK3R2 axis. METHODS In this study, we conducted in vitro experiments by designing overexpression plasmids and small interfering RNAs targeting LncRNA HOTAIR and then transfected them into rheumatoid arthritis fibroblast-like synoviocytes (RA-FLS). We then co-cultured the RA-FLS with human umbilical vein endothelial cells (HUVEC) to establish a RA-FLS-induced HUVEC model. We investigated the effects of LncRNA HOTAIR on the proliferation, migration, lumen forming ability of HUVEC, as well as the expression of synovial endothelial cell markers, angiogenic factors, and the PI3K/AKT pathway. To validate the interactions between LncRNA HOTAIR, miR-126-3p, and PIK3R2, we used bioinformatics and luciferase reporter experiments. We also employed real-time fluorescence quantitative, Western blotanalysis, and immunofluorescence techniques to analyze the target genes and proteins. RESULTS The expression of LncRNA HOTAIR was upregulated in HUVEC induced by RA-FLS. The overexpression of LncRNA HOTAIR significantly increased the expression of vascular endothelial growth factor, basic fibroblast growth factor, CD34, and CD105 in HUVEC, promoting their proliferation, migration, and lumen formation. At the same time, the overexpression of LncRNA HOTAIR inhibited the expression of miR-126-3p, promoted the expression of PIK3R2, activated the PI3K/AKT pathway, and promoted the expression of PI3K, AKT and phosphorylated-AKT, while the silence of LncRNA HOTAIR reversed these expressions. Bioinformatics and double luciferase reporter gene experiments confirmed the targeting relationship among LncRNA HOTAIR, miR-126-3p, and PIK3R2. Finally, the rescue experiments showed that PI3K agonists could reverse the inhibitory effect of silent LncRNA HOTAIR on HUVEC. CONCLUSION LncRNA HOTAIR has the potential to activate the PI3K/AKT pathway, likely through the regulatory axis involving miR-126-3p/PIK3R2, consequently contributing to synovial angiogenesis in RA.

Wu M, Sun J, Wang L, Wang P, Xiao T, Wang S, Liu Q. The lncRNA HOTAIR via miR-17-5p is involved in arsenite-induced hepatic fibrosis through regulation of Th17 cell differentiation.

Abstract
Arsenic compounds are toxins that are widely distributed in the environment. Chronic exposure to low levels of these compounds can cause hepatic fibrosis and other damage. Th17 differentiation of CD4+ T cells and the secretion of IL-17 activates hepatic stellate cells (HSCs), which are involved in hepatic fibrosis, but their mechanisms in arsenic-induced hepatic fibrosis are unclear. We found, in arsenite-induced fibrotic livers of mice, increases of CD4+ T cell infiltration, Th17 cell nuclear receptor retinoic acid receptor-related orphan receptor γt (RORγt), and secretion of the pro-inflammatory cytokine IL-17. There were also elevated levels of the lncRNA, HOTAIR. For Jurkat cells, arsenite elevated levels of HOTAIR and protein levels of RORγt and IL-17A, decreased miR-17-5p, promoted Th17 cell differentiation, and released IL-17. The culture medium of arsenite-treated Jurkat cells activated LX-2 cells. Down-regulation of HOTAIR or up-regulation of miR-17-5p blocked arsenite-induced Th17 cell differentiation, which inhibited the LX-2 cell activation. However, down-regulation of HOTAIR and miR-17-5p reversed this inhibitory effect. For mice, silencing of HOTAIR diminished the hepatic levels of RORγt and IL-17A and alleviated arsenite-induced hepatic fibrosis. These results demonstrate that, for CD4+ T cells, arsenite promotes RORγt-mediated Th17 cell differentiation through HOTAIR down-regulation of miR-17-5p, and increases the secretion of cytokine IL-17A, which activates HSCs; the activated HSCs facilitate hepatic fibrosis. The findings reveal a new mechanism and a potential therapeutic target for arsenite-induced hepatic fibrosis.

Abstract
PURPOSE Long noncoding RNAs (lncRNAs) have been gradually regarded as influential indicators of various cancers. The present study aimed to identify the effects of lncRNA HOTAIR on cervical cancer progression. METHODS RNA and protein expressions were quantified by RT-qPCR and western blot assays. Fluorescence in situ hybridization (FISH) assay was carried out to examine the intracellular location of HOTAIR. Cancer cell viability and mobility were detected by CCK-8, colony formation, transwell and wound healing assays. Binding relationships between miR-331-3p and HOTAIR/RCC2 were validated by luciferase reporter assay. RESULTS RT-qPCR assays showed that HOTAIR levels were notably upregulated in cervical cancer tissues and cell lines. Furthermore, a fluorescence in situ hybridization (FISH) assay suggested that HOTAIR was mostly located in the cytoplasm of cancer cells, indicating a sponging function. CCK-8, colony formation, Transwell and wound-healing assays indicated that knockdown of HOTAIR in HeLa and SiHa cells significantly reduced cell growth, migration and invasion. Subsequently, miR-331-3p was proven to be the target molecule of HOTAIR. In addition, results from Pearson's correlation analysis indicated negative correlation between HOTAIR and miR-331-3p in cervical cancer tissues. HOTAIR negatively modulated miR-331-3p expression. Ultimately, the target gene of miR-331-3p was verified to be RCC2, and miR-331-3p negatively modulated RCC2 expression. In addition, analysis on clinical cervical cancer tissues confirmed the negative correlation between miR-331-3p and RCC2. HOTAIR and RCC2 showed oncogenic functions in HeLa and SiHa cells, while miR-331-3p exerted the reverse effect. CONCLUSIONS HOTAIR plays a carcinogenic role in cervical cancer by targeting the miR-331-3p/RCC2 axis. Moreover, clinical cervical cancer tissues confirmed the negative correlation between miR-331-3p with lncRNA HOTAIR and RCC2. These data suggested an underlying therapeutic target for cervical cancer.

Abstract
BACKGROUND Since the role of long non-coding RNA (lncRNA) HOTAIR is yet to be established in non-small cell lung cancer (NSCLC), we tried to explore the expression of lncRNA HOTAIR in NSCLC and evaluate the correlation between the combined detection of lncRNA HOTAIR and routine tumour markers and the pathological staging of lung cancer. METHODS This study prospectively included 148 patients with NSCLC selected from our hospital from January 2017 to September 2020 as the lung cancer group, and 148 healthy volunteers who referred for physical examination were selected as the control group. Fluorescence in situ hybridisation was used to detect the expression of lncRNA HOTAIR in the cancerous tissues and adjacent tissues of lung cancer patients; the immunofluorescence method was used to detect the serum NSE, CEA and CYFRA21-1 levels of the two groups of testers. Correlation analysis was used to evaluate any relation between cancer staging and markers. In addition, ROC curve analysis was used to estimate sensitivity, specificity, positive predictive value, and negative predictive value. RESULTS The expression of lncRNA HOTAIR in lung cancer tissues was higher than control or surrounding tissue (p < 0.05). Also, high levels of NSE, CEA and CYFRA21-1 were observed in lung cancer group (p < 0.05). In both N and T stage, the expression of lncRNA HOTAIR combined with NSE, CEA and CYFRA21-1 levels increased with the increase in the number of stages (p < 0.05). The results of single factor analysis showed that NSE, CEA, CYFRA21-1 and lncRNA HOTAIR all have appropriate diagnostic value for detecting lung cancer (specificity of 92.6, 91.5, 90.6, 86.9%, respectively and the sensitivity of 61.3, 62.9, 55.4, 52.3%, respectively). CONCLUSION LncRNA HOTAIR is a novel diagnostic test with high diagnostic value for detecting of pathological staging of NSCLC; however, the diagnostic accuracy of lncRNA HOTAIR is not higher than other tumour biomarkers.

Abstract
Long noncoding RNAs (lncRNAs) are a group of transcripts, more than 200 bp in size and regulate cell proliferation, differentiation and apoptosis. LncRNA HOX Transcript Antisense Intergenic RNA (HOTAIR) promotes tumor progression and increases cancer susceptibility by regulating microRNA expression and function. HOTAIR regulates miR-130a-3p expression in hepatocellular carcinoma cells. Bioinformatics analysis revealed that Suv39H1 contained a putative binding site for miR-130a-3p. We speculate that LncRNA HOTAIR promotes the proliferation and invasion/metastasis of breast cancer (BC) cells by targeting the miR-130a-3p/Suv39H1 axis. High HOTAIR expression facilitated BC cell growth and metastasis. HOTAIR functioned as a ceRNA by sponging miR-130a-3p and subsequently promoted Suv39H1-mediated AKT/mTOR signaling. Suv39H1 restoration abolished the effects of HOTAIR knockdown on BC cell growth and metastasis. HOTAIR facilitated the Suv39H1-mediated AKT/mTOR pathway by acting as a molecular sponge of miR-130a-3p.Our results provide a better understanding of the interactions of HOTAIR and miR-103a-3p/Suv39H1 in BC and a potential prognostic biomarker and therapeutic target for BC. HOTAIR expression is frequently up-regulated in BC. HOTAIR promotes BC cell proliferation and metastasis. HOTAIR acts as a ceRNA by sponging miR-130a-3p. Suv39H1 is a direct target of miR-130a-3p. HOTAIR plays a concogenic role in BC via Suv39H1-mediated AKT/mTOR pathway.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Hepatocellular carcinoma (HCC) is a liver malignancy which lacks effective treatment and has a poor prognosis. β-Elemene refers to a natural Curcuma wenyujin-derived single molecular entity, which exhibits various biological activities, and is especially well-known for it's antitumor properties. AIM OF THE RESEARCH LncRNA HOTAIR, SP1, and PDK1 have displayed oncogenic roles in many tumors, participating in the initiation and progression of cancers by mediating multiple signaling pathways. However, there are only a few reports about their roles and mutual relationship in the growth of HCC cells. Therefore, this study aimed to investigate the expression of LncRNA HOTAIR, SP1, and PDK1 and their interaction with β-Elemene in HCC cells. MATERIALS AND METHODS MTT, a Colony formation assay, and flow cytometry were employed to evaluate the growth of HCC and LO2 cells under β-Elemene. LncRNA HOTAIR, SP1 and PDK1 plasmids were transfected into HCC cells by a transient transfection assay, and the expression and interaction of LncRNA HOTAIR, SP1 and PDK1 were assessed via qRT-PCR and western blotting. RESULTS β-Elemene suppressed HCC cell growth through the downregulation of LncRNA HOTAIR, SP1 and PDK1. The results demonstrated a reciprocal interaction among LncRNA HOTAIR, SP1 and PDK1. Exogenous overexpression LncRNA HOTAIR or SP1 eliminated the suppressive effects of β-Elemene on them, and both of which regulated PDK1 expression in HCC cells. Additionally, exogenously overexpressed SP1 or LncRNA HOTAIR prevented β-Elemene inhibition of the protein-level expression of PDK1, whereas overexpressing PDK1 had no effect on SP1, though it still weakened the inhibition of cell growth and LncRNA HOTAIR expression by β-Elemene. CONCLUSION β-Elemene suppresses HCC cell proliferation via through the regulation of LncRNA HOTAIR, SP1, PDK1 and their interaction.

Abstract
Purpose Papillary thyroid carcinoma (PTC) is the most common type of thyroid cancer. LncRNA HOTAIR (HOx Transcript AntIsense RNA) and Galectin-3 are involved in PTC. This study explored the clinical effect of lncRNA HOTAIR/Galectin-3 on PTC patients. Methods Subjects were assigned into PTC (160 cases) and benign thyroid tumor groups (150 cases). Fasting peripheral venous blood was collected. LncRNA HOTAIR/Galectin-3 expressions in serum were detected. Subjects were assigned into HOTAIR/Glactin-3 high/low expression groups and their correlation with age, gender, BMI, tumor size, pathological stage, TSH, TPO-Ab, and TG-Ab in PTC was analyzed. Receiver operating characteristic (ROC) curve was conducted on diagnostic efficacy of HOTAIR or/and Galectin-3. The difference of area under the curve (AUC) was compared and analyzed. Results HOTAIR and Glactin-3 were higher in PTC group and correlated with tumor pathological stage. Higher HOTAIR/Glactin-3 expression indicated a more advanced TNM stage. LncRNA HOTAIR was positively correlated with TPO-Ab and TG-Ab. AUC of HOTAIR for PTC diagnosis was 0.895, with 96.00% specificity and 80.63% sensitivity. AUC of Glactin-3 for PTC diagnosis was 0.817, with 66.67% specificity and 78.75% sensitivity. AUC of HOTAIR combining with Glactin-3 for PTC diagnosis was 0.969 with 96.00% specificity and 87.50% sensitivity. AUC of lncRNA HOTAIR was higher than that of Glactin-3, while AUC of the combination was higher than that of lncRNA HOTAIR or Glactin-3. Conclusion LncRNA HOTAIR and Glactin-3 were highly expressed in PTC. The combination detection of lncRNA HOTAIR/Glactin-3 had higher diagnostic efficiency on the differential diagnosis of benign thyroid tumor and PTC.

Abstract
Ischemic stroke (IS), caused by a permanent or transient local reduction in blood supply to the brain, is one of the most widespread causes of public health problems in modern society. Long non-coding RNA (LncRNA) has been reported to be related to angiogenesis following IS. In this study, we explored the effect and potential molecular mechanism of lncRNA homeobox antisense non-coding RNA (HOTAIR) in IS. Permanent middle cerebral artery occlusion (pMCAO) model and oxygen and glucose deprivation (OGD) model were established. HOTAIR was increased in vivo and in vitro models post-ischemic. HOTAIR knockdown promoted neurological function recovery, manifesting in decreased modified neurological severity score, cerebral infarcted area, apoptosis and inflammation, and improved balance ability, spatial learning and memory ability. Silencing HOTAIR also improved the viability of OGD-induced N2a cells, and attenuated apoptosis and inflammation. HOTAIR can compete with KLF6 to bind to miR-148a-3p. miR-148a-3p knockdown or KLF6 overexpression partially reversed the effect of sh-HOTAIR on OGD-induced N2a cells. HOTAIR suppressed the activation of STAT3 pathway via the miR-148a-3p/KLF6 axis. To summarize, this study demonstrated that lncRNA HOTAIR absorbed miR-148a-3p and up-regulated KLF6 expression through ceRNA mechanism, and inhibited STAT3 pathway, promoted apoptosis and inflammation, and aggravated neurological injury post-IS.

Abstract
BACKGROUND/AIM There has been increasing evidence for the function of long non-coding RNA (lncRNA) in nasopharyngeal carcinoma (NPC). We aim to delve into the position of lncRNA HOX antisense intergenic RNA (HOTAIR), together with enhancer of zeste homolog 2 (EZH2), E-cadherin and trimethylation of lysine 27 on histone H3 (H3K27me3) in NPC. METHODS HOTAIR, EZH2, and E-cadherin expression in NPC tissues and cells were tested. NPC cell biological functions were examined through gain-of and loss-of function assays. The mechanism of lncRNA HOTAIR/E-cadherin/EZH2/H3K27 axis in NPC was decoded. RESULTS LncRNA HOTAIR and EZH2 were highly expressed in NPC, and E-cadherin was lowly expressed. Down-regulation of HOTAIR or EZH2 inhibited NPC cell progression and tumor growth. HOTAIR recruited histone methylase EZH2 to mediate trimethylation of H3K27 and regulated E-cadherin expression. CONCLUSION HOTAIR inhibits E-cadherin by stimulating the trimethylation of H3K27 to promote NPC cell progression through recruiting histone methylase EZH2.

Abstract
Traumatic brain injury (TBI) is one of the leading causes of death worldwide. Long non-coding RNAs (LncRNAs) have been reported to be closely associated with various diseases, but their roles in TBI has not been fully elucidated. The purpose of this study was to elucidate the underlying mechanism of LncRNA HOTAIR in TBI-induced microglial activation and inflammatory factor release. In vivo mouse TBI model and in vitro microglia activation model were established by Feeney's free-fall impact method and by LPS stimulation, respectively. The expression of LncRNA HOTAIR in activated microglia was detected by qRT-PCR. After shRNA knocked down, the expressions of LncRNA HOTAIR and microglia activation marker Iba-1 in microglia were detected by qRT-PCR and Western blot and by ELISA that detected the concentration of inflammatory factor in cell culture supernatants. The relationship between LncRNA HOTAIR and MYD88 in mouse microglia BV2 cells was observed by RNA pull-down assay. Furthermore, the effect of LncRNA HOTAIR on MYD88 stability was assessed by cycloheximide (CHX)-chase and by immunoprecipitation and ubiquitination assays that analyzed MYD88 ubiquitination. LncRNA HOTAIR was abnormally highly expressed in activated microglia. By Western blot and ELISA, the knockdown of LncRNA HOTAIR in microglia significantly repressed microglia activation and inflammatory factor release. By RNA pull-down assay, LncRNA HOTAIR could bind to MYD88 protein. Besides, by cycloheximide (CHX)-chase and immunoprecipitation and ubiquitination assays, the overexpression of the LncRNA HOTAIR enhanced the stability of MYD88 protein and inhibited Nrdp1-mediated ubiquitination of MYD88 protein. After the transfection of shRNA-HOTAIR and shRNA-HOTAIR+pcDNA-MYD88 into microglia, shRNA-HOTAIR could significantly inhibit the activation of microglia and the release of inflammatory factors, while these effects were reversed after the transfection of pcDNA-MYD88. Our experimental data indicated that LncRNA HOTAIR was highly expressed in activated microglia, and our further studies had found that the interference with LncRNA HOTAIR could repress microglia activation and inflammatory factor release via promoting Nrdp1-mediated ubiquitination of MYD88 protein.

Abstract
OATP1B1 is an important drug transporter with a complex regulatory mechanism. In this study, we wanted to investigate how LncRNA HOTAIR regulates the expression of OATP1B1 through its action on miR-206/miR-613 in HepG2 cells. The expression level of LncRNA HOTAIR, miR-206/miR-613, and OATP1B1 mRNA was detected by RT-qPCR, and the OATP1B1 protein level was detected by Western blot. The competitive endogenous RNA mechanism was validated by bioinformatics analysis and a dual-luciferase reporter gene assay. Our results showed that over- or under-expression of LncRNA HOTAIR correspondingly significantly increased or decreased the protein level of OATP1B1 in HepG2 cells, while no significant change in OATP1B1 mRNA level was observed. In addition, the stimulatory or inhibitory effect of LncRNA HOTAIR on OATP1B1 protein expression was correspondingly reversed by miR-206/miR-613 mimic or miR-206/miR-613 inhibitor. Finally, the reporter gene assay revealed that LncRNA HOTAIR can sponge miR-206/miR-613, which breaks the binding site of miR-206/miR-613 and OATP1B1 mRNA 3'-UTR, eliminating the stimulatory effect of LncRNA HOTAIR on OATP1B1 protein. Thus, we conclude that LncRNA HOTAIR can affect the expression of OATP1B1 in HepG2 cells by sponging miR-206/miR-613, which, in turn, prevents the binding of miR-206/miR-613 and OATP1B1 mRNA 3'-UTR.

Abstract
Osteosarcoma (OS) is a common primary malignant bone tumor among adolescences, and the emergence of multidrug resistance poses a huge challenge for clinical treatment of OS. LncRNA HOTAIR (HOX antisense intergenic RNA) has been reported to be associated with many malignancies, including OS. However, the underlying mechanisms of HOTAIR involved in drug resistance in OS are obscure. Our study showed that HOTAIR was upregulated in cisplatin (DDP)-resistant OS tissues and cells. HOTAIR knockdown decreased the DDP resistance, drug resistance-related gene expression, cell proliferation, and invasion and promoted apoptosis of Saos2/DDP, MG-63/DDP, and U2OS/DDP cells. Mechanism researches displayed that miR-106a-5p was downregulated in DDP-resistant OS tissues and cells. MiR-106a-5p directly bound with HOTAIR and was regulated by HOTAIR. Moreover, STAT3 was inhibited by miR-106a-5p at a post-transcriptional level, and the transfection of miR-106a-5p reversed the upregulation of STAT3 caused by HOTAIR overexpression. The increase or decrease of miR-106a-5p suppressed the effect of HOTAIR upregulation or downregulation on DDP resistance, cell proliferation, invasion, and apoptosis of Saos2/DDP, MG-63/DDP, and U2OS/DDP cells. What's more, the transfection of STAT3 siRNA reversed the decrease of DDP resistance, cell proliferation, and invasion and rescued the increase of apoptosis induced by miR-106a-5p inhibition. These data suggested that HOTAIR enhanced DDP resistance of Saos2/DDP, MG-63/DDP, and U2OS/DDP cells by affecting cell proliferation, invasion, and apoptosis via miR-106a-5p/STAT3 axis.

Abstract
BACKGROUND Intervertebral disc degeneration (IDD) has a complicated and enigmatic pathogenic process. Accumulating evidence shows that long non-coding RNAs (LncRNAs) play a role in the pathogenesis of IDD. This study aimed to investigate the expression and role of the LncRNA HOTAIR in IDD pathogenesis. METHODS Nucleus pulposus (NP) tissue samples from 10 patients with idiopathic scoliosis and 10 patients with lumbar disc herniation were collected. qRT-PCR was used to assess the expression of HOTAIR and ECM-related genes; western blotting was used to detect the expression of senescence biomarkers, apoptosis-related proteins, and Wnt/β-catenin pathway; flow cytometry was used to detect apoptosis; and the MTT assay was used to determine cell proliferation. Moreover, a classic needle-punctured rat tail model was used to investigate the role of HOTAIR in IDD in vivo. RESULTS The results showed that the expression of HOTAIR significantly increased during IDD progression. The overexpression of HOTAIR was found to induce nucleus pulposus (NP) cell senescence, apoptosis, and extracellular matrix (ECM) degradation. HOTAIR silencing by RNA interference in NP cells prevented interleukin-1β-induced NP cell senescence, apoptosis, and ECM degradation. Furthermore, we found that the Wnt/β-catenin pathway played a role in regulating HOTAIR to induce these changes in NP cells. Moreover, HOTAIR inhibition in a rat model effectively attenuated IDD symptoms in vivo. CONCLUSIONS Our findings confirmed that HOTAIR promoted NP cell senescence, apoptosis, and ECM degradation via the activation of the Wnt/β-catenin pathway, while silencing HOTAIR attenuated this degeneration process, indicating a potential therapeutic target against IDD.

Abstract
BACKGROUND Cartilage damage is a crucial feature involved in several pathological conditions characterized by joint disorders, such as osteoarthritis and rheumatoid arthritis. Accumulated evidences showed that Wnt/β-catenin pathway plays a role in the pathogenesis of cartilage damage. In addition, it is experimentally documented that lncRNA (long non-coding RNA) HOTAIR plays a key role in the regulation of Wnt/β-catenin pathway based on directly decreased WIF-1 expression. Further, it is reported that Wnt/β-catenin pathway is a potent pathway to regulate the expression of MMP-13, which is responsible for degradation of collagen type II in articular cartilage. It is increasingly recognized that systems modeling approach provides an opportunity to understand the complex relationships and direct quantitative analysis of dynamic network in various diseases. RESULTS A dynamic network of lncRNA HOTAIR-mediated Wnt/β-catenin pathway regulating MMP-13 is developed to investigate the dynamic mechanism of the network involved in the pathogenesis of cartilage damage. Based on the network modeling, the potential therapeutic intervention point Axin is predicted and confirmed by the experimental validation. CONCLUSIONS Our study provides a promising strategy for revealing potential dynamic mechanism and assessing potential targets which contribute to the prevention of the pathological conditions related to cartilage damage.

Abstract
BACKGROUND/AIMS The long noncoding RNA homeobox (HOX) transcript antisense intergenic RNA (HOTAIR) has been demonstrated to be a vital modulator in the proliferation and metastasis of ovarian cancer cells, but its potential molecular mechanism remains to be elucidated. In the current study, we aimed to uncover the biological role of lncRNA HOTAIR and its underlying regulatory mechanism in the progression and metastasis of ovarian cancer. METHODS HOTAIR expression was detected by quantitative RT-PCR (qRT-PCR) and northern blotting. The SKOV3 ovarian cancer cell line was chosen for the subsequent assays. In addition, the molecular mRNA and protein expression levels were examined by qRT-PCR and western blotting. The competitive endogenous RNA (ceRNA) mechanism was validated by bioinformatics analysis and a dual luciferase reporter gene assay. RESULTS HOTAIR expression was significantly higher in ovarian carcinoma tissues and cell lines than in the control counterparts. Both CCND1 and CCND2 were downstream targets of miR-206. The inhibition of HOTAIR elevated the expression of miR-206 and inhibited the expression of CCND1 and CCND2. Moreover, CCND1 and CCND2 were highly expressed in ovarian cancer tissues, and their expression was positively correlated with HOTAIR expression. Finally, the functional assays indicated that the anticancer effects of miR-206 could be rescued by the simultaneous overexpression of either CCND1 or CCND2 in ovarian cancer. CONCLUSION HOTAIR enhanced CCND1 and CCND2 expression by negatively modulating miR-206 expression and stimulating the proliferation, cell cycle progression, migration and invasion of ovarian cancer cells.

Abstract
Background MicroRNA-122 (miR-122), a pivotal liver-specific miRNA, is frequently repressed in hepatocellular carcinoma (HCC) and associated with poor prognosis. Long non-coding RNA (lncRNA) HOTAIR has been proved to function as an oncogene in multiple cancers including HCC. However, the relationship between HOTAIR and miR-122 in HCC remains largely unknown. Methods We investigated the function of HOTAIR and miR-122 in HCC cell models and a xenograft mouse model. The regulatory network between HOTAIR and miR-122 was further detected following overexpression or knockdown of HOTAIR. DNA methylation status of miR-122 promoter region, as well as expression levels of DNMTs, EZH2 and Cyclin G1 were analyzed. Findings In this study, we found that HOTAIR was highly expressed whereas miR-122 was suppressed in HCC, and HOTAIR negatively regulated miR-122 expression in HCC cells. Furthermore, knockdown of HOTAIR dramatically inhibited HCC cell proliferation and induced cell cycle arrest in vitro and suppressed tumorigenicity in vivo by upregulating miR-122 expression. Mechanistically, a CpG island was located in the miR-122 promoter region. HOTAIR epigenetically suppressed miR-122 expression via DNMTs-mediated DNA methylation. Moreover, HOTAIR upregulated DNMTs expression via EZH2. In addition, suppression of miR-122 induced by HOTAIR directly reactivated oncogene Cyclin G1 expression. Collectively, our results suggest that HOTAIR epigenetically suppresses miR-122 expression via DNA methylation, leading to activation of Cyclin G1 and promotion of tumorigenicity in HCC, which provide new insight into the mechanism of HOTAIR-mediated hepatocarcinogenesis via suppressing miR-122. HOTAIR is highly expressed in HCC, and negatively regulates miR-122 expression in HCC cells. HOTAIR increased HCC cell proliferation and tumor growth through downregulating miR-122 expression. HOTAIR epigenetically suppressed miR-122 expression via DNMTs-mediated DNA methylation. HOTAIR upregulated DNMTs expression via EZH2. HOTAIR increased cyclin G1 expression through repressing miR-122.

Abstract
OBJECTIVE This study investigated the role of long noncoding RNA (lncRNA) HOX transcript antisense RNA (HOTAIR) in kidney injury induced by urine-derived sepsis (US). MATERIALS AND METHODS An Escherichia coli suspension was injected into the distal ureter of adult male Sprague Dawley rats to establish a US model. Lipopolysaccharides (LPSs) were used to induce an in vitro septic model. The interaction between HOTAIR and microRNA 22 (miR-22) was detected by RNA precipitation and RNA pull-down assays. The expression of HOTAIR, miR-22, and high mobility group box 1 (HMGB1) were detected by quantitative real time polymerase chain reaction (qRT-PCR) and Western blot analyses. RESULTS Compared with a sham group, HOTAIR was upregulated in kidney tissues of the US group. HOTAIR was also upregulated in LPS-induced human renal tubular epithelial cells (HK-2). Furthermore, HOTAIR negatively regulated miR-22 and promoted apoptosis of HK-2 cells. HOTAIR also promoted HMGB1 expression and HK-2 cell apoptosis by inhibiting miR-22. In addition, the miR-22/HMGB1 pathway was involved in LPS-induced HK-2 cell apoptosis. In vivo experiments showed that HOTAIR negatively modulated miR-22 and positively modulated HMGB1 and that HOTAIR knockdown decreased renal function indicators (blood urea nitrogen [BUN] and serum creatinine). CONCLUSION HOTAIR was upregulated in sepsis-induced kidney injury, which promoted HK-2 cell apoptosis in kidney injury through the miR-22/HMGB1 pathway.

Abstract
Non-small-cell lung cancer (NSCLC) is one of the leading causes of cancer-related death worldwide, and the 5-year survival rate is still low despite advances in diagnosis and therapeutics. A long noncoding RNA (lncRNA) HOX antisense intergenic RNA (HOTAIR) has been revealed to play important roles in NSCLC carcinogenesis but the detailed mechanisms are still unclear. In the current study, we aimed to investigate the regulation between the lncRNA HOTAIR and p53 in the NSCLC patient samples and cell lines. Our results showed that HOTAIR expression was significantly higher in the cancer tissues than that in the adjacent normal tissue, and was negatively correlated with p53 functionality rather than expression. When p53 was overexpressed in A549 cells, the lncRNA HOTAIR expression was downregulated, and the cell proliferation rate and cell invasion capacity decreased as a consequence. We identified two binding sites of p53 on the promoter region of HOTAIR, where the p53 protein would bind to and suppress the HOTAIR mRNA transcription. Inversely, overexpression of lncRNA HOTAIR inhibited the expression of p53 in A549 cells. Mechanistic studies revealed that HOTAIR modified the promoter of p53 and enhanced histone H3 lysine 27 trimethylation (H3K27me3). These studies identified a specific negative regulation loop of lncRNA HOTAIR and p53 in NSCLC cells, which revealed a new understanding of tumorigenesis in p53 dysfunction NSCLC cells.
