Abstract
Lung adenocarcinoma (LUAD) poses a significant global health burden owing to its high incidence rate and unfavorable prognosis, driven by frequent recurrence and drug resistance. Understanding the biological mechanisms underlying LUAD is imperative to developing advanced therapeutic strategies. Recent research has highlighted the role of dysregulated microRNAs (miRNAs) in LUAD progression through diverse signaling pathways, including the Wnt and AKT pathways. Of particular interest is the novel pathological mechanism involving the interaction between competing endogenous RNAs (ceRNAs) and miRNAs. This review critically analyzed the impact of aberrant miRNA expression on LUAD development, shedding light on the associated signaling pathways. It also highlighted the emerging significance of ceRNA‑miRNA interactions in LUAD pathogenesis. Elucidating the intricate regulatory networks involving miRNAs and ceRNAs presents a promising avenue for the development of potential therapeutic interventions and diagnostic biomarkers in LUAD. Further research in this area is essential to advance precision medicine approaches and improve patient outcomes.

TIAM2 Contributes to Osimertinib Resistance, Cell Motility, and Tumor-Associated Macrophage M2-like Polarization in Lung Adenocarcinoma. Int J Mol Sci 2022; 23:ijms231810415. [PMID: 36142328 PMCID: PMC9499457 DOI: 10.3390/ijms231810415] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2022] [Revised: 09/05/2022] [Accepted: 09/05/2022] [Indexed: 11/30/2022] Open
Abstract
Background: Osimertinib-based therapy effectively improves the prognosis of lung adenocarcinoma (LUAD) patients with epidermal growth factor receptor mutations. However, patients will have cancer progression after approximately one year due to the occurrence of drug resistance. Extensive evidence has revealed that lipid metabolism and tumor-associated macrophage (TAM) are associated with drug resistance, which deserves further exploration. Methods: An osimertinib resistance index (ORi) was built to investigate the link between lipid metabolism and osimertinib resistance. The ORi was constructed and validated using TCGA and GEO data, and the relationship between ORi and immune infiltration was discussed. Weighted gene co-expression network analysis based on the M2/M1 macrophage ratio determined the hub gene TIAM2 and the biological function of TIAM2 in LUAD was verified in vitro. Results: ORi based on nine lipid metabolism-related genes was successfully constructed, which could accurately reflect the resistance of LUAD patients to osimertinib, predict the prognosis, and correlate with M2-like TAM. Additionally, TIAM2 was found to increase osimertinib tolerance, enhance cell motility, and promote M2-like TAM polarization in LUAD. Conclusions: The lipid metabolism gene is strongly connected with osimertinib resistance. TIAM2 contributes to osimertinib resistance, enhances cell motility, and induces M2-like TAM polarization in LUAD.

Abstract
Background Given that long non-coding RNAs (lncRNAs) involved in the tumor initiation or progression of the endometrium and that competing endogenous RNA (ceRNA) plays an important role in increasingly more biological processes, lncRNA-mediated ceRNA is likely to function in the pathogenesis of uterine corpus endometrial carcinoma (UCEC). Our present study aimed to explore the potential molecular mechanisms for the prognosis of UCEC through a lncRNA-mediated ceRNA network. Methods The transcriptome profiles and corresponding clinical profiles of UCEC dataset were retrieved from Clinical Proteomic Tumor Analysis Consortium (CPTAC) and The Cancer Genome Atlas (TCGA) databases respectively. Differentially expressed genes (DEGs) in UCEC samples were identified via "Edge R" package. Then, an integrated bioinformatics analysis including functional enrichment analysis, tumor infiltrating immune cell (TIIC) analysis, Kaplan-Meier curve, Cox regression analysis were conducted to analyze the prognostic biomarkers. Results In the CPTAC dataset of UCEC, a ceRNA network comprised of 36 miRNAs, 123 lncRNAs and 124 targeted mRNAs was established, and 8 of 123 prognostic-related Differentially Expressed long noncoding RNAs (DElncRNAs) were identified. While in the TCGA dataset, a ceRNA network comprised of 38 miRNAs, 83 lncRNAs and 110 targeted mRNAs was established, and 2 of 83 prognostic-related DElncRNAs were identified. After filtered by risk grouping and Cox regression analysis, 10 prognostic-related lncRNAs including LINC00443, LINC00483, C2orf48, TRBV11-2, MEG-8 were identified. In addition, 33 survival-related Differentially Expressed messenger RNA (DEmRNAs) in two ceRNA networks were further validated in the Human Protein Atlas Portal (HPA) database. Finally, six lncRNA/miRNA/mRNA axes were established to elucidate prognostic regulatory roles in UCEC. Conclusions Several prognostic lncRNAs are identified and prognostic model of lncRNA-mediated ceRNA network is constructed, which promotes the understanding of UCEC development mechanisms and potential therapeutic targets.

Abstract
Background The pivotal role of long noncoding RNAs (lncRNAs) in cancer immune responses has been well established. This study was conducted with the aim of exploring the molecular mechanism of lncRNA small nucleolar RNA host gene 12 (SNHG12) in immune escape of non-small cell lung cancer (NSCLC). Methods Expression of lncRNA SNHG12, programmed cell death receptor ligand 1 (PD-L1), ubiquitin-specific protease 8 (USP8), and human antigen R (HuR) in NSCLC tissues and cells was measured, and their binding relationship was determined. NSCLC cell proliferation and apoptosis were assessed. Peripheral blood mononuclear cells (PBMCs) were co-cultured with NSCLC cells. The ratio of CD8+ T cells, PBMC proliferation, and inflammatory factors were determined. lncRNA SNHG12 localization was assessed via subcellular fractionation assay. The half-life period of mRNA was determined using actinomycin D. Xenograft tumor models were established to confirm the role of lncRNA SNHG12 in vivo. Results LncRNA SNHG12 was found to be prominently expressed in NSCLC tissues and cells, which was associated with a poor prognosis. Silencing lncRNA SNHG12 resulted in the reduction in proliferation and the promotion of apoptosis of NSCLC cells, while simultaneously increasing PBMC proliferation and the ratio of CD8+ T cells. Mechanically, the binding of lncRNA SNHG12 to HuR improved mRNA stability and expression of PD-L1 and USP8, and USP8-mediated deubiquitination stabilized the protein level of PD-L1. Overexpression of USP8 or PD-L1 weakened the inhibition of silencing lncRNA SNHG12 on the immune escape of NSCLC. Silencing lncRNA SNHG12 restricted tumor growth and upregulated the ratio of CD8+ T cells by decreasing USP8 and PD-L1. Conclusion LncRNA SNHG12 facilitated the immune escape of NSCLC by binding to HuR and increasing PD-L1 and USP8 levels.

Abstract
In cancer biology, ETS transcription factors promote tumorigenesis by mediating transcriptional regulation of numerous genes via the conserved ETS DNA-binding domain. MicroRNAs (miRNAs) act as posttranscriptional regulators to regulate various tumor-promoting or tumor-suppressing factors. Interactions between ETS factors and miRNAs regulate complex tumor-promoting and tumor-suppressing networks. This review discusses the progress of ETS factors and miRNAs in cancer research in detail. We focused on characterizing the interaction of the miRNA/ETS axis with competing endogenous RNAs (ceRNAs) and its regulation in posttranslational modifications (PTMs) and the tumor microenvironment (TME). Finally, we explore the prospect of ETS factors and miRNAs in therapeutic intervention. Generally, interactions between ETS factors and miRNAs provide fresh perspectives into tumorigenesis and development and novel therapeutic approaches for malignant tumors.

Abstract
E2F8 can modulate development and progression of various cancers including cervical cancer, breast cancer and hepatocellular carcinoma. But its mechanism in lung adenocarcinoma (LUAD) remains underexplored. In this study, we conducted a series of experiments including qRT-PCR, western blot, CCK-8, scratch healing assay, Transwell, and flow cytometry. Through these assays, we confirmed the notable overexpression of E2F8 in LUAD and its promoting effects on LUAD cell proliferation, migration and invasion. Subsequently, microRNA-1-3p that was negatively associated with E2F8 expression was identified through bioinformatics analysis. qRT-PCR was then carried out for quantification of microRNA-1-3p expression, which displayed low microRNA-1-3p expression in LUAD cells. In addition, dual-luciferase reporter gene assay was utilized for validating the targeted relationship between microRNA-1-3p and E2F8. The results denoted that microRNA-1-3p could bind to the promoter region of E2F8. Finally, the results of rescue experiment revealed that microRNA-1-3p negatively modulated E2F8 level. It regulated NF-κB pathway to repress LUAD cell proliferative, migratory, and invasive properties, lead to cell cycle arrest in G0/G1 phase, and enhance cell apoptosis level. This study unraveled that microRNA-1-3p/E2F8 constrained LUAD malignant progression through NF-κB pathway, which may provide possible targets for LUAD diagnosis and treatment.

Abstract
OBJECTIVE To seek out the mechanism by which C1QTNF6 mediates lung adenocarcinoma (LUAD). METHODS Differentially expressed mRNAs and miRNAs in LUAD were analyzed using bioinformatics. In LUAD cells, C1QTNF6 mRNA and miR-184 expression were evaluated with qRT-PCR, and C1QTNF6 protein level was assessed by western blot. Cellular behaviors were assessed by colony formation, CCK-8, Transwell, and wound healing methods. The binding ability of miR-184 to C1QTNF6 was observed by dual-luciferase assay. RESULTS High expression of C1QTNF6 in LUAD stimulated cancer cellular behaviors. MiR-184 was lowly expressed in LUAD and downregulated C1QTNF6 expression. MiR-184 restrained LUAD cell processes by targeting C1QTNF6. CONCLUSION MiR-184 repressed LUAD cell processes via mediating C1QTNF6. MiR-184 and C1QTNF6 are expected to be indicators for LUAD treatment.

Long non-coding RNA GAS6-AS1 enhances breast cancer cell aggressiveness by functioning as a competing endogenous RNA of microRNA-215-5p to enhance SOX9 expression. Exp Ther Med 2022; 23:109.

Abstract
Long non-coding (lnc) RNAs play crucial functions in human cancer. However, until recently, the involvement of the lncRNA GAS6-AS1 in breast cancer (BCa) malignancy has not been studied exhaustively. The roles and underlying mode of action of GAS6-AS1 action in BCa progression were examined through functional experiments. A decline in GAS6-AS1 level led to a significant decrease in BCa cell proliferation, and the ability for colony formation. Here, GAS6-AS1 competed as endogenous RNA by sequestering microRNA-215-5p (miR-215-5p) causing an enhanced expression of SRY-box transcription factor 9 (SOX9). The effects of silencing GAS6-AS1 on BCa malignant phenotypes could be ameliorated by inhibiting miR-215-5p or restoring SOX9. Thus, GAS6-AS1 acted as a lncRNA that drives tumor in BCa, and enabled progression of BCa through miR-215-5p /SOX9 axis regulation. These outcomes show that the GAS6-AS1/miR-215-5p/SOX9 axis is a potentially effective target for cancer treatment and management.

Abstract
Spindle and Kinetochore Associated Complex Subunit 3 (SKA3) is crucial for anaphase mitosis. However, the relationship between SKA3 and lung adenocarcinoma (LUAD) has not been fully clarified. Differentially expressed genes were first identified by analyzing data from TCGA. It was found that miR-133b was significantly lowly expressed in LUAD, while SKA3 was remarkably highly expressed. Cell Counting Kit-8 (CCK8), wound healing assay and Transwell assay uncovered that overexpressing miR-133b could inhibit the proliferation, invasion and migration of LUAD cells. In addition, the targeting relationship between miR-133b and SKA3 was also verified by dual-luciferase analysis. Moreover, it was proved by the rescue assay that the overexpression of miR-133b significantly downregulated SKA3 in LUAD cells. All in all, these findings revealed the role of miR-133b and SKA3 in regulating the proliferation, migration, and invasion of LUAD cells. This study could yield new information about the mechanisms of LUAD.

Abstract
Resistance against conventional chemotherapeutic agents is one of the main reasons for tumor relapse and poor clinical outcomes in cancer patients. Various mechanisms are associated with drug resistance, including drug efflux, cell cycle, DNA repair and apoptosis. Doxorubicin (DOX) is a widely used first-line anti-cancer drug that functions as a DNA topoisomerase II inhibitor. However, DOX resistance has emerged as a large hurdle in efficient tumor therapy. Furthermore, despite its wide clinical application, DOX is a double-edged sword: it can damage normal tissues and affect the quality of patients’ lives during and after treatment. It is essential to clarify the molecular basis of DOX resistance to support the development of novel therapeutic modalities with fewer and/or lower-impact side effects in cancer patients. Long non-coding RNAs (lncRNAs) have critical roles in the drug resistance of various tumors. In this review, we summarize the state of knowledge on all the lncRNAs associated with DOX resistance. The majority are involved in promoting DOX resistance. This review paves the way to introducing an lncRNA panel marker for the prediction of the DOX response and clinical outcomes for cancer patients.

Abstract
Long non-coding (lnc)RNA ABHD11-AS1 participates in the development and progress of various cancers, but its role in colorectal cancer (CRC) remains poorly known. In the present study, public database analysis and quantitative reverse transcription PCR of CRC and normal tissues showed that ABHD11-AS1 was overexpressed in CRC and associated with poor prognosis in CRC patients. Both in vitro and in vivo experiments demonstrated that loss-of-function of ABHD11-AS1 attenuated the proliferation, migration, and invasion of CRC cells and induced their apoptosis. Transcriptome sequencing and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis indicated that the phosphoinositide 3 kinase (PI3K)/Akt signaling pathway is a potential target of ABHD11-AS1. Additionally, we noted that ABHD11-AS1 deficiency reduced integrin subunit alpha (ITGA)5 expression, and impaired the phosphorylation of P85, focal adhesion kinase (FAK), and Akt1 in CRC cell lines and tumor tissues of nude mice. Furthermore, we observed that ITGA5 overexpression abrogated the effect of ABHD11-AS1 knockdown on the proliferation and invasion abilities of CRC cells. Taken together, our studies suggest that lncRNA ABHD11-AS1 promotes proliferation, migration, and invasion in CRC by activating the ITGA5/Fak/PI3K/Akt signaling pathway, and that the ITGA5/Fak/PI3K/Akt axis is a promising target for CRC therapy.

Abstract
Diffuse large B-cell lymphoma (DLBCL) remains to be a high aggressive and invasive malignancy with enigmatic etiology. Ectopic expression of long non-coding RNAs is widely involved in the progression of human cancers. We discovered that LINC00857 level was remarkably elevated in DLBCL tissues compared with non-tumor controls. High LINC00857 level predicts lower survival rate, more advanced tumor node metastasis and larger tumor size. LINC00857 overexpression promoted DLBCL cell proliferation and facilitated cell cycle as evidenced by elevated Cyclin D1 and proliferating cell nuclear antigen (PCNA) accompanying with reduced p21 level. LINC00857 overexpression also suppressed DLBCL cell apoptosis as evidenced by elevated Bcl-2 protein level, reduced Bax and cleaved caspase-3 protein levels. On the contrary, LINC00857 knockdown using short hairpin RNAs inhibited DLBCL cell proliferation yet induced cell apoptosis. LINC00857 knockdown also repressed tumor growth in vivo, concomitant with decreased Ki67 level. Besides, microRNA miR-370 was down-regulated in DLBCL tissues and served as a competitive endogenous RNA (ceRNA) target of LINC00857. We further validated that chromobox homolog 3 (CBX3) served as a downstream target gene of miR-370-3p. LINC00857 level was reversely correlated with miR-370-3p level yet positively correlated with CBX3 level. In addition, CBX3 overexpression alleviated the impact of LINC00857 knockdown on DLBCL cell survival. In conclusion, our findings indicated that LINC00857 contributes to DLBCL proliferation and lymphomagenesis through regulating miR-370-3p/CBX3 axis.

Abstract
BACKGROUND ZNF674-AS1, a recently characterized long noncoding RNA, shows prognostic significance in hepatocellular carcinoma and glioma. However, the expression and function of ZNF674-AS1 in non-small cell lung cancer (NSCLC) are unclear. METHODS In this work, we investigated the expression of ZNF674-AS1 in 83 pairs of NSCLC specimens and adjacent noncancerous lung tissues. The clinical significance of ZNF674-AS1 in NSCLC was analyzed. The role of ZNF674-AS1 in NSCLC growth and cell cycle progression was explored. RESULTS Our data show that ZNF674-AS1 expression is decreased in NSCLC compared to normal tissues. ZNF674-AS1 downregulation is significantly correlated with advanced TNM stage and decreased overall survival of NSCLC patients. Overexpression of ZNF674-AS1 inhibits NSCLC cell proliferation, colony formation, and tumorigenesis, which is accompanied by a G0/G1 cell cycle arrest. Conversely, knockdown of ZNF674-AS1 enhances the proliferation and colony formation of NSCLC cells. Biochemically, ZNF674-AS1 overexpression increases the expression of p21 through downregulation of miR-423-3p. Knockdown of p21 or overexpression of miR-423-3p blocks ZNF674-AS1-mediated growth suppression and G0/G1 cell cycle arrest. In addition, ZNF674-AS1 expression is negatively correlated with miR-423-3p in NSCLC specimens. CONCLUSIONS ZNF674-AS1 suppresses NSCLC growth by downregulating miR-423-3p and inducing p21. This work suggests the therapeutic potential of ZNF674-AS1 in the treatment of NSCLC.

Abstract
Long non-coding (lnc) RNAs serve crucial functions in human cancers. However, the involvement of the lncRNA B4GALT1-antisense RNA 1 (AS1) in non-small cell lung cancer (NSCLC) has not been extensively studied. Reverse transcription-quantitative PCR was performed to detect B4GALT1-AS1 levels in NSCLC tissues and cell lines. Potential influences of B4GALT1-AS1 on biological functions of NSCLC were assessed through a series of in vitro experiments, and the molecular mechanism was determined via RNA immunoprecipitation (RIP) and bioinformatics analyses. The results of the present study demonstrated that knockdown of B4GALT1-AS1 significantly attenuated the proliferative ability and clonality of H1299 and A549 cells. In the present study, B4GALT1-AS1 competed as an endogenous RNA by sequestering microRNA-30e (miR-30e) leading to an enhanced expression of SRY-box transcription factor 9 (SOX9). The effects of silencing B4GALT1-AS1 on NSCLC cells proliferation could be ameliorated by inhibiting miR-30e or restoring SOX9. Hence, B4GALT1-AS1 acted as a lncRNA that drives tumor progression in NSCLC via the regulation of the miR-30e/SOX9 axis. The findings of the present study indicated that the B4GALT1-AS1/miR-30e/SOX9 axis maybe an effective target for NSCLC treatment and management.

[PMID: 32944001 PMCID: PMC7491190 DOI: 10.1186/s12935-020-01543-x] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2020] [Accepted: 09/05/2020] [Indexed: 12/24/2022] Open
Abstract
Background It has been well documented that long non-coding RNAs (lncRNAs) regulate numerous characteristics of cancer, including proliferation, migration, metastasis, apoptosis, and even metabolism. LncRNA BCYRN1 (BCYRN1) is a newly identified brain cytoplasmic lncRNA with 200 nucleotides that was discovered to be highly expressed in tumour tissues, including those of hepatocellular carcinoma, gastric cancer and lung cancer. However, the roles of BCYRN1 in colorectal cancer (CRC) remain obscure. This study was designed to reveal the role of BCYRN1 in the occurrence and progression of CRC. Methods RT-PCR was used to detect the expression level of BCYRN1 in tumour tissues and CRC cell lines. BCYRN1 was knocked down in CRC cells, and cell proliferation changes were evaluated by cell counting kit-8 (CCK-8), 5-ethynyl-2′-deoxyuridine (EdU), and Ki-67 and proliferating cell nuclear antigen (PCNA) expression assays. Cell migration and invasion changes were evaluated by wound healing, Transwell and invasion-related protein expression assays. Flow cytometry analysis was used to assess whether BCYRN1 regulates the apoptosis of CRC cells. The dual luciferase reporter gene detects the competitive binding of BCYRN1 to miR-204-3p. In vivo experiments were performed to evaluate the effect of BCYRN1 on tumour development. TargetScan analysis and dual luciferase reporter gene assays were applied to detect the target gene of miR-204-3p. Rescue experiments verified that BCYRN1 affects CRC by regulating the effect of miR-204-3p on KRAS. Results We found that compared with normal tissues and human intestinal epithelial cells (HIECs), CRC tumour tissues and cell lines had significantly increased BCYRN1 levels. We further determined that knockdown of BCYRN1 inhibited the proliferation, migration, and invasion and promoted the apoptosis of CRC cells. In addition, bioinformatics analysis and dual luciferase reporter assay showed that BCYRN1 served as a competitive endogenous RNA (ceRNA) to regulate the development of CRC through competitively binding to miR-204-3p. Further studies proved that overexpression of miR-204-3p reversed the effects of BCYRN1 on CRC. Next, TargetScan analysis and dual luciferase reporter assay indicated that KRAS is a target gene of miR-204-3p and is negatively regulated by miR-204-3p. A series of rescue experiments showed that BCYRN1 affected the occurrence and development of CRC by regulating the effects of miR-204-3p on KRAS. In addition, tumorigenesis experiments in a CRC mouse model confirmed that BCYRN1 downregulation effectively inhibited tumour growth. Conclusions Our findings suggest that BCYRN1 plays a carcinogenic role in CRC by regulating the miR-204-3p/KRAS axis.

Abstract
Pulmonary neuroendocrine neoplasms (NENs) are classified into low-grade neuroendocrine tumors and high-grade neuroendocrine carcinomas (NECs). There are significant differences in therapeutic strategies of the different NEN subtypes, and therefore, precise classification of pulmonary NENs is critical. However, challenges in pulmonary NEN classification include overlap of diagnostic histological features among the subtypes and reduced or negative expression of neuroendocrine markers in poorly differentiated pulmonary NECs. Recently, transcription factor insulinoma-associated protein 1 (INSM1) was identified as a sensitive marker of neuroendocrine and neuroepithelial differentiation. In this study, INSM1 expression was detected by immunohistochemistry in greater than 94% of pulmonary NENs, indicating that it is a highly sensitive marker of pulmonary NENs and is useful to detect poorly differentiated pulmonary NECs. Although there are well-established morphological and immunohistologic criteria to diagnose pulmonary NENs, there is no universal consensus regarding prognostic markers of pulmonary NENs. Studies have shown that non-small cell lung cancers express long non-coding RNAs (lncRNAs), which regulate gene expression, epithelial-to-mesenchymal transition, and carcinogenesis. We characterized expression and function of lncRNAs, including HOX transcript antisense RNA (HOTAIR), maternally expressed 3 (MEG3), and prostate cancer antigen 3 (PCA3) in pulmonary NENs, including typical carcinoid tumors, atypical carcinoid tumors, small cell lung carcinoma (SCLC/NEC), and large cell neuroendocrine carcinoma (LCNEC/NEC). In situ hybridization and real-time polymerase chain reaction studies showed higher expression (p < 0.01) of all lncRNAs in SCLC/NEC. Small interfering RNA studies indicated a role for MEG3 and PCA3 in tumor proliferation. Therefore, these lncRNAs may serve as prognostic indicators of pulmonary NEN aggressiveness and as possible therapeutic targets.

[PMID: 32818819 DOI: 10.1016/j.molimm.2020.07.021] [Citation(s) in RCA: 36] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2020] [Revised: 07/27/2020] [Accepted: 07/30/2020] [Indexed: 01/04/2023]
Abstract
Here, we aimed to investigate the role of long noncoding RNA (lncRNA) THRIL in septic-induced acute lung injury. C57BL/6 mice were injected with Adenoviruses (Ad)-shTHRIL or negative control (NC) before caecal ligation and puncture (CLP) operation. MPVECs were transfected with Ad-shTHRIL or NC, followed by lipopolysaccharide (LPS) treatment. MiR-424 and Rho-associated kinase 2 (ROCK2) were predicted and verified as direct targets of THRIL and miR-424, respectively, by using dual-luciferase reporter assay. ROCK2 overexpression vector and shTHRIL were co-transfected into mouse pulmonary microvascular endothelial cells for 24 h before LPS treatment. Our results showed that THRIL was highly expressed in the lung of sepsis mice. CLP triggered severe lung injury and apoptosis in mice, which was abolished by THRIL knockdown. Moreover, CLP treatment visibly increased protein concentration, the number of total cell of neutrophils, and macrophages in bronchoalveolar lavage fluid (BALF). Besides, elevated protein levels of tumor necrosis factor-α, interleukin-1β, and interleukin-6 were observed in both lung and BALF. However, inhibition of THRIL reduced the number of inflammatory cells and the production of pro-inflammatory cytokines in sepsis mouse model. The effect of THRIL on inflammatory response and apoptosis in the lung was confirmed in sepsis cell model. Moreover, mechanistic studies have shown that THRIL up-regulated ROCK2 level through sponging miR-424. Furthermore, ROCK2 overexpression reversed the inhibitory effects of THRIL knockdown on LPS-induced inflammatory response and apoptosis. Overall, in vivo and in vitro results suggested that THRIL accelerates sepsis-induced lung injury by sponging miR-424 and further restoring ROCK2.

Abstract
OBJECTIVE This study aimed at probing into the effect of lncRNA NCK1-AS1 on proliferation, migration and invasion of non-small cell lung cancer (NSCLC) cells and its regulatory function on miR-512-5p/p21 molecular axis. METHODS Quantitative real-time polymerase chain reaction (qRT-PCR) was used to assess the expressions of NCK1-AS1 and miR-512-5p in NSCLC tissues and cell lines. The alterations of cell proliferation, migration, invasion and cell cycle were examined by cell counting kit-8 (CCK-8) assay, BrdU experiment, Transwell experiment and flow cytometry, respectively. The dual-luciferase reporter assay and RNA immunoprecipitation experiment were performed to validate the binding relationships between miR-512-5p and NCK1-AS1, and miR-512-5p the 3'UTR of p21 mRNA. Western blot was used to determine the effects of NCK1-AS1 and miR-512-5p on p21 protein expression. RESULTS NCK1-AS1 expression was up-regulated in NSCLC tissues and cells, and its high expression was correlated with shorter overall survival time and faster progression of patients. Overexpression of NCK1-AS1 promoted NSCLC cell proliferation, migration and invasion, and accelerated the cell cycle, whereas NCK1-AS1 siRNA inhibited these malignant biological behaviors, and arrested cell cycle. NCK1-AS1 could bind to miR-512-5p, p21 was verified as a target gene of miR-512-5p, and NCK1-AS1 could up-regulate the expression of p21 in NSCLC cells via repressing miR-512-5p expression. CONCLUSION NCK1-AS1 promotes NSCLC progression by regulating miR-512-5p/p21 molecular axis.
