Abstract
Esophageal adenocarcinoma (EAC) occurs following a series of histological changes through epithelial-mesenchymal transition (EMT). A variable expression of normal and aberrant genes in the tissue can contribute to the development of EAC through the activation or inhibition of critical molecular signaling pathways. Gene expression is regulated by various regulatory factors, including transcription factors and microRNAs (miRs). The exact profile of miRs associated with the pathogenesis of EAC is largely unknown, though some candidate miRNAs have been reported in the literature. To identify the unique miR profile associated with EAC, we compared normal esophageal tissue to EAC tissue using bulk RNA sequencing. RNA sequence data was verified using qPCR of 18 selected genes. Fourteen were confirmed as being upregulated, which include CDH11, PCOLCE, SULF1, GJA4, LUM, CDH6, GNA12, F2RL2, CTSZ, TYROBP, and KDELR3 as well as the downregulation of UGT1A1. We then conducted Ingenuity Pathway Analysis (IPA) to analyze for novel miR-gene relationships through Causal Network Analysis and Upstream Regulator Analysis. We identified 46 miRs that were aberrantly expressed in EAC compared to control tissues. In EAC tissues, seven miRs were associated with activated networks, while 39 miRs were associated with inhibited networks. The miR-gene relationships identified provide novel insights into potentially oncogenic molecular pathways and genes associated with carcinogenesis in esophageal tissue. Our results revealed a distinct miR profile associated with dysregulated genes. The miRs and genes identified in this study may be used in the future as biomarkers and serve as potential therapeutic targets in EAC.

Abstract
LincRNA-P21 is a tumor suppressor in esophageal squamous cell carcinoma (ESCC). Cell adhesion modules play vital roles in cell-cell and cell-extracellular matrix (ECM) interactions and malignant cancer progression. In this study, we investigate whether lincRNA-P21 exerts its functions by regulating the cell adhesion molecule cadherin 5 (CDH5) in ESCC. Moreover, the RNA binding protein (RBP) mediators of lincRNA-P21 and CDH5 are further examined. Cell viability, growth and migratory ability are assessed by calcein-AM/PI double staining, CCK-8, EdU, Transwell, and wound healing assays. The expression of collagen I and fibronectin is examined by immunofluorescence (IF). LincRNA-P21 and CDH5 are quantified by RT-qPCR and western blot analysis. Potential lincRNA-P21 targets are identified by RNA sequencing. RBPs that can interact with lincRNA-P21 and CDH5 are identified by RNA immunoprecipitation (RIP) assay. LincRNA-P21 knockdown increases cell viability, growth, cell migration, and collagen I and fibronectin expression in ESCC cells. LincRNA-P21 depletion induces the dysregulation of 316 genes, including CDH5, in TE-1 cells. CDH5 is identified as a downstream molecule of lincRNA-P21 given its close correlation with cell adhesion, ECM reconstruction, and cancer progression. LincRNA-P21 exerts its functions by negatively regulating CDH5 expression. YTH domain containing 1 (YTHDC1) mediates the regulatory effect of lincRNA-P21 on CDH5. LincRNA-P21 knockdown elevates cell viability and growth, promotes cell migration, and induces ECM reorganization by upregulating CDH5 via RBP YTHDC1 in ESCC.

Abstract
T-2 toxin and selenium deficiency are considered important etiologies of Kashin-Beck disease (KBD), although the exact mechanism is still unclear. To identify differentially expressed microRNAs (DE-miRNAs) in the articular cartilage of rats exposed to T-2 toxin and selenomethionine (SeMet) supplementation, thirty-six 4-week-old Sprague Dawley rats were divided into a control group (gavaged with 4% anhydrous ethanol), a T-2 group (gavaged with 100 ng/g·bw/day T-2 toxin), and a T-2 + SeMet group (gavaged with 100 ng/g·bw/day T-2 toxin and 0.5 mg/kg·bw/day SeMet), respectively. Toluidine blue staining was performed to detect the pathological changes of articular cartilage. Three rats per group were randomly selected for high-throughput sequencing of articular cartilage. Target genes of DE-miRNAs were predicted using miRanda and RNAhybrid databases, and the Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway were enriched. The network map of miRNA-target genes was constructed using Cytoscape software. The expression profiles of miRNAs associated with KBD were obtained from the Gene Expression Omnibus database. Additionally, the DE-miRNAs were selected for real-time quantitative PCR (RT-qPCR) verification. Toluidine blue staining demonstrated that T-2 toxin damaged articular cartilage and SeMet effectively alleviated articular cartilage lesions. A total of 50 DE-miRNAs (28 upregulated and 22 downregulated) in the T-2 group vs. the control group, 18 DE-miRNAs (6 upregulated and 12 downregulated) in the T-2 + SeMet group vs. the control group, and 25 DE-miRNAs (5 upregulated and 20 downregulated) in the T-2 + SeMet group vs. the T-2 group were identified. Enrichment analysis showed the target genes of DE-miRNAs were associated with apoptosis, and in the MAPK and TGF-β signaling pathways in the T-2 group vs. the control group. However, the pathway of apoptosis was not significant in the T-2 + SeMet group vs. the control group. These results indicated that T-2 toxin induced apoptosis, whereas SeMet supplementation antagonized apoptosis. Apoptosis and autophagy occurred simultaneously in the T-2 + SeMet group vs. T-2 group, and autophagy may inhibit apoptosis to protect cartilage. Compared with the GSE186593 dataset, the evidence of miR-133a-3p involved in apoptosis was more abundant. The results of RT-qPCR validation were consistent with RNA sequencing results. Our findings suggested that apoptosis was involved in articular cartilage lesions induced by T-2 toxin, whereas SeMet supplementation antagonized apoptosis, and that miR-133a-3p most probably played a central role in the apoptosis process.

Abstract
BACKGROUND Oesophageal carcinoma (EC) is one of the types of prevalent malignant cancer in the globe. Many researchers reported the vital role played by long-coding RNAs in EC. In the current research, we investigated the mechanisms of the action of lncRNA BBOX1-AS1 in EC progression. METHODS In EC tissues and EC cells, the expression levels of miR-361-3p along with COL1A1 and BBOX1-AS1 were detected through RT-qPCR or western blotting. MiR-361-3p interactions with BBOX1-AS1 or COL1A1 were verified through Luciferase reporter and RIP tests. Loss of function combined with caspase-3 activity, CCK-8 and Transwell assays was performed to investigate cell apoptosis, proliferation and migration, respectively. Knockdown of BBOX1-AS1 was used for evaluating BBOX1-AS1 effects on tumour development in vivo. RESULTS BBOX1-AS1 was remarkably elevated in EC tissues and cells. In addition, the silencing of BBOX1-AS1 attenuated the cell viability, cell migration and enhanced cell apoptosis of EC, as well as suppressed EC tumour formation in vivo. Moreover, BBOX1-AS1 was found to be a sponge of miR-361-3p, which downregulated miR-361-3p expression. MiR-361-3p inhibitor rescued the anti-tumour effect of BBOX1-AS1 knockdown on the progression of EC. Furthermore, we discovered that miR-361-3p specially bound to COL1A1 3'UTR and downregulated COL1A1 and COL1A1 reduction declined the promoting effect of silencing miR-361-3p on EC cell malignant phenotypes. CONCLUSION BBOX1-AS1 facilitated the EC development and malignancy via miR-361-3p/COL1A1 axis, indicating BBOX1-AS1 could be a novel therapy target for the diagnostic of EC.

Abstract
Abstract
Colorectal cancer (CRC) is a common malignant gastrointestinal tumor. Long noncoding RNAs (lncRNAs) are revealed to be critically involved in CRC progression, providing new direction for exploring the pathogenesis of CRC. This study aimed to explore the biological functions and regulatory mechanisms of lncRNA AC125257.1 in CRC. Western blotting and reverse-transcription quantitative polymerase chain reaction were used for the measurement of gene expression. Cell counting kit-8 assay and flow cytometry analysis were used to explore the effects of AC125257.1 on CRC cell viability and apoptosis. RNA pull-down and immunoprecipitation assays were performed for validating the binding between AC125257.1 and its potential downstream microRNA. Results showed that lncRNA AC125257.1 expression was upregulated in CRC cells and tumor tissues. AC125257.1 enhanced cell viability and suppressed apoptosis of CRC cells. Moreover, the knockdown of AC125257.1 suppressed CRC progression in vitro and inhibited tumor growth in vivo. miR-133a-3p was revealed to bind with AC125257.1 in CRC cells. CASC5 was proved to be targeted by miR-133a-3p. Moreover, rescue assays indicated that the knockdown of AC125257.1 suppressed the pathogenic overexpression of CASC5. To conclude, AC125257.1 aggravates CRC development via miR-873-5p/CASC5 axis. Our findings might suggest a novel perspective that AC125257.1 may become the target for CRC treatment.

Abstract
Engagement of regulated cell death in keratinocytes plays a crucial role in the pathogenesis and development of skin disorders associated with UV radiation. However, it remains unclear how microRNAs (miRNAs) participate in the regulation of UV-caused keratinocyte death. In this study, we found that miR-133a-3p was decreased in the epidermis of UVB-challenged mice and UVB-irradiated keratinocyte cell line HaCaT cells. The intradermal injection of agomir miR-133a-3p ameliorated skin damage of UVB-challenged mice, especially epidermal necrosis. Meanwhile, the injection inhibited apoptosis indicator PARP cleavage and pyroptosis indicator GSDME cleavage in the epidermis. In UVB-challenged HaCaT cells, transfection of miR-133a-3p mimic or inhibitor alleviated or aggravated UVB-induced apoptosis and GSDME-mediated pyroptosis respectively. miR-133a-3p was also involved in the effects of metformin treatment on alleviating skin damage in UVB-challenged mice and on inhibiting apoptosis and GSDME-mediated pyroptosis in UVB-irradiated HaCaT cells. We confirmed that CYLD is a target gene of miR-133a-3p and participates in the protective effects of miR-133a-3p on inhibiting UVB-caused apoptosis and GSDME-mediated pyroptosis in keratinocytes. This study indicates a pivotal role for miR-133a-3p of keratinocytes in UVB-caused skin damage. Alleviating skin photodamage by restoring the decrease of miR-133a-3p can be considered a potential therapeutic approach.

Abstract
Fracture healing is a complex process with multiple overlapping metabolic and differentiation phases. Small non-coding RNAs are involved in the regulation of fracture healing and their presence in circulation is under current interest due to their obvious value as potential biomarkers. Circulating microRNAs (miRNAs) have been characterized to some extent but the current knowledge on tRNA-derived small RNA fragments (tsRNAs) is relatively scarce, especially in circulation. In this study, the spectrum of circulating miRNAs and tsRNAs was analysed by next generation sequencing to show their differential expression during fracture healing in vivo. Analysed tsRNA fragments included stress-induced translation interfering tRNA fragments (tiRNAs or tRNA halves) and internal tRNA fragments (i-tRF), within the size range of 28–36 bp. To unveil the expression of these non-coding RNAs, genome-wide analysis was performed on two months old C57BL/6 mice on days 1, 5, 7, 10, and 14 (D1, D5, D7, D10, and D14) after a closed tibial fracture. Valine isoacceptor tRNA-derived Val-AAC 5′end and Val-CAC 5′end fragments were the major types of 5′end tiRNAs in circulation, comprising about 65 % of the total counts. Their expression was not affected by fracture. After a fracture, the levels of two 5′end tiRNAs Lys-TTT 5′ and Lys-CTT 5′ were decreased and His-GTG 5′ was increased through D1-D14. The level of miR-451a was decreased on the first post-fracture day (D1), whereas miR-328-3p, miR-133a-3p, miR-375-3p, miR-423-5p, and miR-150-5p were increased post-fracture. These data provide evidence on how fracture healing could provoke systemic metabolic effects and further pinpoint the potential of small non-coding RNAs as biomarkers for tissue regeneration.

Abstract
There is evidence suggesting the participation of non-coding RNAs in male reproductive dysfunction induced by lead, and the significance of microRNAs has been highlighted recently because of their essential roles in gene regulatory networks. To comprehensively understand the functions of miRNA and the regulatory networks, RNA sequencing was carried out to obtain miRNA expression profiles in mice testes exposed to low dose Pb for 90 days at the onset of puberty. In total, 44 differentially expressed miRNAs with 26 up-regulated and 18 down-regulated were identified between 200 mg/L Pb group and control group (p < 0.05). Enrichment analysis confirmed that the target genes of DE miRNAs might participate in the metabolism of testicular cells. Furthermore, a miRNA-mRNA co-expression network consisting of 19 miRNAs and 106 mRNAs and a competing endogenous RNA network of lncRNA-miRNA-mRNA including 179 genes were established. Finally, the expressions of 4 miRNAs (mmu-miR-451a, mmu-miR-133a-3p, mmu-miR-1a-3p and mmu-miR-486a-3p) and 4 mRNAs (Gramd1b, Tcf7l2, Mov10 and Srcin1) involved in regulatory networks were verified by RT-qPCR. In conclusion, our research might provide targets for the mechanism studies of miRNAs in reproductive toxicity of Pb.

Abstract
Collagen type I alpha 1 (COL1A1), a member of the collagen family, is involved in epithelial-mesenchymal transition, which is closely linked to malignant tumorigenesis. COL1A1 is highly expressed in various cancers and regulates various cellular processes, including cell proliferation, metastasis, apoptosis, and cisplatin resistance. COL1A1 is also associated with cancer progression and prognosis; elevated COL1A1 expression is associated with poor prognosis in cancer patients. However, the main role of COL1A as a cancer-promoting factor in specific tumors has not been reported. Additionally, the protein levels and mechanisms of action of this protein differ among tumor types. This review discusses current research progress concerning COL1A1 in different tumor types, and then summarizes its contributions to cancer progression, thus providing a basis for follow-up research and potential targets for cancer treatment.

Abstract
Parathyroid hormone is the main endocrine regulator of extracellular calcium and phosphorus levels. Secondary hyperparathyroidism–induced endothelial dysfunction may be related to calcium homeostasis disorders. Here, we investigated the effects of parathyroid hormone on human umbilical vein endothelial cells (HUVECs) and characterized the involvement of store-operated Ca2+ entry (SOCE) and the nuclear factor of activated T cells (NFAT) signaling pathway. We used immunoblot experiments to find that parathyroid hormone significantly enhanced the expression of the Orai1 channel, a type of channel mediating SOCE, SOCE activity, and Orai1-mediated proliferation of HUVECs but did not increase Orai2 and Orai3. RNA-seq was utilized to identify 1,655 differentially expressed genes (823 upregulated and 832 downregulated) in parathyroid hormone–treated HUVECs as well as enhanced focal adhesion signaling and expression levels of two key genes, namely, COL1A1 and NFATC1. Increased protein and mRNA expression levels of COL1A1 and NFATC1 were confirmed by immunoblotting and quantitative RT-PCR, respectively. Cytosol and nuclei fractionation experiments and immunofluorescence methods were used to show that parathyroid hormone treatment increased NFATC1 nuclear translocation, which was inhibited by a calcineurin inhibitor (CsA), a selective calmodulin antagonist (W7), an Orai channel inhibitor (BTP2), or Orai1 small interfering RNA (siRNA) transfection. Parathyroid hormone also increased COL1A1 expression, cell migration, and proliferation of HUVECs. The PTH-induced increase in HUVEC migration and proliferation were inhibited by CsA, W7, BTP2, or COL1A1 siRNA transfection. These findings indicated that PTH increased Orai1 expression and Orai1-mediated SOCE, causing the nuclear translocation of NFATC1 to increase COL1A1 expression and COL1A1-mediated HUVEC migration and proliferation. These results suggest potential key therapeutic targets of Orai1 and the downstream calmodulin/calcineurin/NFATC1/COL1A1 signaling pathway in parathyroid hormone–induced endothelial dysfunction and shed light on underlying mechanisms that may be altered to prevent or treat secondary hyperparathyroidism–associated cardiovascular disease.

Abstract
Objective To investigate the tumorigenic role of spen paralogue and orthologue C-terminal domain-containing 1 (SPOCD1) in hepatocellular carcinoma (HCC) and identify the upstream regulatory mechanism. Methods We analyzed SPOCD1 and miR-133-3p expression in normal and HCC tissues from the Cancer Genome Atlas and UALCAN databases, and in normal hepatocytes and HCC cell lines by real-time quantitative polymerase chain reaction and western blot. We identified the miR-133a-3p-binding site on the SPOCD1 3ʹ-untranslated region using TargetScan. Hierarchical regulation was confirmed by luciferase assay and miR-133a-3p overexpression/silencing. Cell proliferation, migration, invasion, and colony formation were assessed by MTT, scratch, transwell, and clonogenic assays, respectively. Results SPOCD1 was highly expressed in HCC tissues and cell lines, while miR-133a-3p expression was significantly downregulated. Kaplan–Meier analysis indicated that high SPOCD1 expression was significantly associated with poor survival. TargetScan and luciferase reporter assay revealed that SPOCD1 was the downstream target of miR-133a-3p. Overexpression of miR-133a-3p significantly inhibited the expression of SPOCD1, while miR-133a-3p knockdown significantly increased SPOCD1 expression. Conclusion SPOCD1, regulated by miR-133a-3p, promotes HCC cell proliferation, migration, invasion, and colony formation. This study provides the first evidence for the role of the miR-133a-3p/SPOCD1 axis in HCC tumorigenesis.

Abstract
This article describes several recent examples of miRNA governing the regulation of the gene expression involved in bone matrix construction. We present the impact of miRNA on the subsequent steps in the formation of collagen type I. Collagen type I is a main factor of mechanical bone stiffness because it constitutes 90–95% of the organic components of the bone. Therefore, the precise epigenetic regulation of collagen formation may have a significant influence on bone structure. We also describe miRNA involvement in the expression of genes, the protein products of which participate in collagen maturation in various tissues and cancer cells. We show how non-collagenous proteins in the extracellular matrix are epigenetically regulated by miRNA in bone and other tissues. We also delineate collagen mineralisation in bones by factors that depend on miRNA molecules. This review reveals the tissue variability of miRNA regulation at different levels of collagen maturation and mineralisation. The functionality of collagen mRNA regulation by miRNA, as proven in other tissues, has not yet been shown in osteoblasts. Several collagen-regulating miRNAs are co-expressed with collagen in bone. We suggest that collagen mRNA regulation by miRNA could also be potentially important in bone metabolism.

Abstract
Background and Aim: Some studies have verified that miR-133a played an inhibitory role in several cancers. Whereas, the effect of miRNA-133a in colorectal cancer (CRC) has not been fully elucidated. Our study aims to confirm UBA2 as a direct target gene of miRNA-133a and explore the upstream modulatory molecules of miR-133a. In addition, their impacts on the biological characteristics of CRC cells were assessed. Methods: QRT-PCR analyzed miR-133a expression levels in colorectal cells including HCT116, SW48 cells and human normal colorectal cell line NCM460. A serial biological experiment assessed miR-133a effects on cell proliferation, migration, invasion and apoptosis capacities in HCT116 and SW48 cells. MiRNA targeting gene prediction and a dual luciferase assay were employed to confirm miR-133a-targeted UBA2. Transcription factors (TFs) FOXD3 was identified as an upstream regulator of miR-133a via JASPAR. The influence of miR-133a and FOXD3 on UBA2 expression was analyzed by qRT-PCR or western blot. Results: miR-133a was lowly expressed in CRC cells. High miRNA-133a expression suppressed the proliferation, migration, invasion and enhanced apoptosis capacities of CRC cells. MiR-133a targeted the UBA2 mRNA 3ʹUTR area and reduced UBA2 protein expression. We also unveiled that FOXD3 high-expression significantly raised miR-133a expression and diminished UBA2 expression. We also discovered that high miR-133a expression augmented the effects of elevated FOXD3 expression on CRC cell proliferation, migration and invasion, whereas, low miR-133a expression generated the opposite outcomes. Conclusion: FOXD3 induced miRNA-133a directly targeting UBA2 could affect the progression and growth of CRC.

Abstract
Background: Gastrointestinal cancers patients might experience multiple primary tumors in the digestive tract. Therefore, identifying potential biomarkers can help us better understand the underlying mechanism. From the GEO database, four profiles of gastrointestinal cancers were gathered for the screening process, and six hub genes were found by bioinformatics analysis. Collagen type I alpha 1 chain (COL1A1), one of the hub genes, is a component of the extracellular matrix and is critical for tumor microenvironment. However, the expression level, signaling pathway, prognostic prediction, and immunological value of COL1A1 in different cancers remain unclear. Methods: We comprehensively analyzed gene expression and genetic alteration patterns of COL1A1 among 33 types of malignancies from The Cancer Genome Atlas (TCGA) and the Genotype-Tissue Expression projects. Besides, we explored the correlation of COL1A1 with cancer prognosis, immune infiltrates, PD-L1, tumor mutational burden (TMB)/microsatellite instability status (MSI), and the pathway and drug sensitivity of co-expressed genes. Results: The results showed that COL1A1 was highly expressed and associated with poor prognosis in the majority of cancers. The most common alteration type of COL1A1 was missense mutation, and COL1A1 was associated with poor prognosis in KIRP, LGG, MESO, SKCM, and STAD. For the immunologic significance, COL1A1 expression was closely related to high TMB in THYM, LAML, ACC, KICH, PRAD, and LGG, and high MSI in TGCT, MESO, PRAD, COAD, SARC, and CESC. In addition, COL1A1 was positively correlated with the abundance of CAFs, macrophages, and tumor-infiltrating lymphocytes. However, it was negatively correlated with CD8+ T cells mainly in CESC, HNSC-HPV+, and SKCM. Besides, as a component of the extracellular matrix, COL1A1 was involved in the activation of epithelial-mesenchymal transition (EMT), and high expression of HTRA1 was resistant to multiple drugs. Conclusion:COL1A1 can serve as a prognostic and immunological biomarker in different cancers.

Abstract
Recently, miR-133a-3p has been identified as a marker for human colorectal cancer (CRC) and the association between miR-133a-3p and aquaporin 1 (AQP1) has been described in endothelial cells. However, the regulatory functions of the miR-133a-3p/AQP1 axis remain unclear in CRC. The present study analyzed the expression of miR-133a-3p and AQP1 in CRC tissues (n=56) and cell lines using reverse transcription-quantitative PCR and western blot analysis. The χ2 test was used to assess the associations between miR-133a-3p/AQP1 and clinicopathological features of patients with CRC. Next, the functional role of miR-133a-3p/AQP1 in CRC was evaluated in vitro by performing Cell Counting Kit-8 and Transwell assays. Moreover, the online software tool TargetScan7.1 was used to predict AQP1 as the target gene of miR-133a-3p, followed by validation using a luciferase reporter assay. The results showed that miR-133a-3p was significantly downregulated, while AQP1 was upregulated in CRC tissues and cell lines compared with corresponding controls. Clinically, it was demonstrated that miR-133a-3p/AQP1 expression was significantly associated with tumor TNM stage (P=0.020). Functional experiments indicated that miR-133a-3p-overexpression remarkably suppressed, while knockdown promoted, cell proliferation, migration and invasion in CRC cells. Mechanically, AQP1 was identified and validated as a target gene of miR-133a-3p in CRC cells. The expression level of AQP1 mRNA was not correlated with miR-133a-3p expression in CRC tissues. Furthermore, AQP1-knockdown induced, while overexpression reversed, the suppressive effects of miR-133a-3p on CRC cells. Taken together, these findings suggested that miR-133a-3p might be a tumor suppressor by suppressing cell proliferation, migration and invasion via targeting AQP1.

Abstract
Non-coding microRNAs (miRNAs) have been proposed to play diverse roles in cancer biology, including epithelial-mesenchymal transition (EMT) crucial for cancer progression. Previous comparative studies revealed distinct expression profiles of miRNAs relevant to tumorigenesis and progression of oral cancer. With putative targets of these miRNAs mostly validated in vitro, it remains unclear whether similar miRNA-target relationships exist in vivo. In this study, we employed a hybrid approach, utilizing both Drosophila melanogaster and human oral cancer cells, to validate projected miRNA-target relationships relevant to EMT. Notably, overexpression of dme-miR-133 resulted in significant tissue growth in Drosophila larval wing discs. The RT-PCR analysis successfully validated a subset of its putative targets, including Pde1c. Subsequent experiments performed in oral cancer cells confirmed conserved targeting of human PDE1C by hsa-miR-133. Furthermore, the elevated level of miR-133 and its targeting of PDE1C was positively correlated with enhanced migrative ability of oral cancer cells treated with LPS, along with the molecular signature of a facilitated EMT process induced by LPS and TGF-β. The analysis on the RNAseq data also revealed a negative correlation between the expression level of hsa-miR-133 and the survival of oral cancer patients. Taken together, our mammal-to-Drosophila-to-mammal approach successfully validates targeting of PDE1C by miR-133 both in vivo and in vitro, underlying the promoted EMT phenotypes and potentially influencing the prognosis of oral cancer patients. This hybrid approach will further aid to widen our scope in investigation of intractable human malignancies, including oral cancer.

Abstract
The role of lncRNA HCP5 in esophageal squamous cell carcinoma (ESCC) remains unknown despite its involvement in different malignancies. MTT assay, EdU assay, TUNEL assay, transwell assay, and sphere formation assay were conducted to reveal ESCC cell viability, proliferation, apoptosis, migration, invasion, and stemness characteristics. FISH and subcellular fraction assays were performed to reveal the subcellular location of HCP5 in ESCC cells. Luciferase reporter assay and RIP assay were conducted to explore the downstream axis of HCP5. Our findings revealed that HCP5 expression was at a higher level in ESCC tissues and cells compared to that in control tissues and cells. Additionally, HCP5 promoted ESCC cellular activities by promoting proliferation, migration, invasion ability and stemness characteristics of ESCC cells as well as suppressing cell apoptosis. Furthermore, we found that HCP5 bound with miR-139-5p to upregulate PDE4A via the competing endogenous RNA network in ESCC cells. Importantly, HCP5 was discovered to stimulate the PI3K/AKT/mTOR signaling by regulating the downstream target genes. Finally, rescue assays indicated that HCP5 promoted ESCC cell growth by activating the PDE4A-medaited PI3K/AKT/mTOR pathway. HCP5 promotes ESCC cellular development by modulating the miR-139-5p/PDE4A pathway and stimulating the PI3K/AKT/mTOR signaling pathway, which may be conducive for the improvement of ESCC treatment.

Abstract
Background Gefitinib is an epidermal growth factor receptor tyrosine kinase inhibitor (EGFR‐TKI), clinically used to treat patients with non‐small cell lung cancer driven by EGFR mutations. Unfortunately, EGFR‐TKI resistance has become a clinical problem for the effective treatment of NSCLC patients. The purpose of this study was to explore the effect and mechanism of miR‐133a‐3p on the gefitinib sensitivity of NSCLC cells. Methods The gefitinib‐resistant PC9 (PC9/GR) cells were established through repeated long‐term exposure to gefitinib for half a year. Then, PC9/GR cells were transfected with miR‐133a‐3p mimics and PC9 cells were transfected with miR‐133a‐3p inhibitors to increase or decrease the expression of miR‐133a‐3p. CCK‐8 assay, colony formation assay, and caspase‐3 activity assay were employed to detect cell resistance to gefitinib. Quantitative real‐time PCR and Western blotting were used to evaluate the levels of miR‐133a‐3p, SPAG5, and other related genes. Starbase database was used to predict the target gene of miR‐133a‐3p and the prognosis of NSCLC patients. Target gene of miR‐133a‐3p was verified through dual‐luciferase reporter gene assay. Results MiR‐133a‐3p was significantly downregulated in gefitinib‐resistant cell line PC9/GR vs. gefitinib‐sensitive cell line PC9. Overexpression of miR‐133a‐3p increased the sensitivity of NSCLC cells to gefitinib and vice versa. Furthermore, SPAG5 is an important target gene of miR‐133a‐3p, and SPAG5 can reverse miR‐133a‐3p‐mediated gefitinib sensitivity of NSCLC cells. Conclusions These findings indicated that miR‐133a‐3p/SPAG5 axis played a vital role in acquired resistance to gefitinib in NSCLC cells, and miR‐133a‐3p may represent a potential therapeutic strategy for the treatment of human NSCLC.

Abstract
Proliferative vitreoretinopathy (PVR) is a serious ophthalmic disease and characterized by the formation of proliferative membranes by retinal pigment epithelial (RPE) cells. In PVR, the contraction and traction of the fibrocellular membranes cause retinal detachment, which can cause reduction surgery for retinal detachment to fail. Fibroblast growth factor-2 (FGF-2) causes RPE cells to form extracellular matrix (ECM), promotes chemotaxis, mitosis, and positively promotes the disease process of PVR. Plumbagin (PLB) is a plant small molecule naphthoquinone compound. It has the functions in anti-tumor, anti-inflammatory, inhibit proliferation. We tried to investigate the possible effects of PLB on the biological behavior of ARPE-19 cells induced by FGF-2 and its underlying mechanisms. Our study confirmed that proliferation, migration, and invasion of ARPE-19 cells induced by FGF-2 (10 ng/ml) were significantly inhibited by PLB. PLB also significantly inhibits the expression of MMP-2/-9, collagen I Alpha 1 (Col1A1), collagen IV Alpha 1 (Col4A1), collagen VI Alpha 1 (Col6A1), and the phosphorylation of FGF receptor (FGFR)-1, FGFR-2, ERK, p38, JNK of FGF-2-induced ARPE-19 cells. In summary, PLB inhibits FGF-2-stimulated proliferation, migration, and invasion of ARPE-19 cells, which may take place through inhibiting the expression of MMP-2/-9, Col1A1, Col4A1, Col6A1, and the mitogen-activated protein kinase (MAPK) pathway. PLB may have a preventive effect on proliferation, migration, and invasion of FGF-2-induced ARPE-19 cells.

Abstract
Esophageal cancer (EC) is one of the deadliest cancers worldwide. However, reliable biomarkers for early diagnosis, or those for the prognosis of therapy, remain unfulfilled goals for its subtype esophageal squamous cell carcinoma (ESCC). The purpose of this study was to identify reliable biomarkers for the diagnosis and prognosis of ESCC by gene chip re-annotation technique and downstream bioinformatics analysis. In our research, the GSE53624 dataset was downloaded from the GEO database. Then, we reannotated the gene expression probe and obtained the gene expression matrix. Differential expressed genes (DEGs) were found by R packages and they were subjected to Gene Ontology enrichment analysis and protein–protein interaction (PPI) network construction. As a result, a total of 28,885 mRNA probes were reannotated, among which 210 down-regulated and 80 up-regulated DEGs were screened out. By combining these genes set in clinical prognosis information and Western blot analysis, we found four genes with diagnostic and prognostic significance, including MMP13, SPP1, MMP10, and COL1A1. Furthermore, markers of infiltrating immune cells exhibited different DEG-related immune infiltration patterns.

Abstract
Long-chain noncoding RNAs (lncRNAs) are involved in a wide range of biological and pathological processes in ovarian cancer. The purpose of this study was to investigate the effects of EZH2-mediated ABHD11-AS1 promoter on the pathogenesis of ovarian cancer. The expression levels of EZH2, ABHD11-AS1 and miR-133a-3p were examined in ovarian cancer tissues using reverse transcription-quantitative PCR. Cell proliferation was evaluated using cell counting kit 8 assay, and cell invasion/migration was determined using a Transwell assay. Cell apoptosis was evaluated using flow cytometry. Dual luciferase assay was performed to confirm the interaction between ABHD11-AS1 and miR-133a-3p. The binding site of H3K27me3 on ABHD11-AS1 promoter was confirmed by ChIP. The expression of ABHD11-AS1 was significantly upregulated in ovarian cancer samples, and its levels were closely associated with lymph node metastasis, tumor stage and 3-year survival rate. Furthermore, interference of ABHD11-AS1 suppressed the proliferation, migration and invasion of ovarian cancer cells, while cell apoptosis was promoted. Additionally, miR-133a-3p could be a novel target of ABHD11-AS1, and EZH2-mediated H3K27me3 protein might bind to ABHD11-AS1 promoter directly. Moreover, rescue experiments indicated that the effects caused by ABHD11-AS1 knockdown on the malignant characteristics of ovarian cancer cells were notably enhanced by miR-133a-3p mimics, whereas the influences on cell growth and metastasis induced by overexpressed ABHD11-AS1 were abrogated by the restoration of miR-133a-3p expression. In summary, EZH2-mediated enrichment of H3K27me3 on ABHD11-AS1 promoter could regulate the progression of ovarian cancer via miR-133a-3p. Therefore, EZH2/ABHD11-AS1/miR-133a-3p axis might be a putative candidate for targeted treatment of ovarian cancer.

Abstract
Preeclampsia (PE) is a major cause of the pregnancy morbidity and mortality over the world. Disorganized placentation caused by trophoblast cell abnormity is one of main risk factors to induce PE. MiR-133a-3p has been shown to contain regulatory effects on oxidative stress in the cardiomyocytes. But the effects of miR-133a-3p on oxidative stress-induced apoptosis in the trophoblast cells remain unknown. In this study, trophoblast HTR-8/SVneo cells were transfected with miR-133a-3p mimics and inhibitor. H2O2 (250 microM) treatment of cells was adopted to induce oxidative stress. A series of typical molecular and cellular experiments was subsequently performed in order to investigate this issue. It was found that miR-133a-3p overexpression attenuated the oxidative stress induced by H2O2 through reduced ROS and MDA levels and enhanced antioxidase activities in the trophoblast cells. Overexpressed miR-133a-3p was shown to relieve the oxidative stress-induced apoptosis of HTR-8/SVneo cells. At molecular levels, a direct binding effect of miR-133a-3p on BACH1 was verified. Moreover, miR-133a-3p overexpression also enhanced BACH1 downstream Nrf2/HO-1 signaling to activate antioxidant genes. It is collectively demonstrated that miR-133a-3p can relieve the oxidative stress-induced apoptosis in the trophoblast cells through the BACH1/Nrf2/HO-1 signaling pathway via targeting BACH1 directly. This regulatory mechanism of miR-133a-3p in the trophoblast cells under oxidative stress may give a new perspective for oxidative stress-induced trophoblast cell abnormality and be useful to study more pathological mechanisms of PE.

Abstract
Background The aim of this study was to investigate the circ_0004370 expression in EC, its effects on cell proliferation, apoptosis, migration, invasion, and epithelial–mesenchymal transition (EMT) process, and the underlying regulatory mechanisms in EC. Methods The protein levels of COL1A1 and EMT-related proteins were detected by western blot. The role of circ_0004370 on cell viability, proliferation, and apoptosis was analyzed by Cell Counting Kit-8 (CCK-8) assay, colony formation assay, and flow cytometry, respectively. The transwell assay was used to examine cell migration and invasion. The binding sites between miR-1301-3p and circ_0004370 or COL1A1 were predicted by starbase software and confirmed by dual-luciferase reporter assay and RNA pull-down assay. Results We discovered that circ_0004370 was remarkably upregulated in EC tissues and cells. Knockdown of circ_0004370 inhibited cell proliferation, migration as well as invasion, and promoted apoptosis in vitro, while its effect was rescued by miR-1301-3p inhibition. And circ_0004370 mediated the EMT process in EC cells. Moreover, we explored its regulatory mechanism and found that circ_0004370 directly bound to miR-1301-3p and COL1A1 was verified as a target of miR-1301-3p. COL1A1 was highly expressed in EC cells and upregulation of COL1A1 reversed the effects of miR-1301-3p on cell proliferation, migration, invasion, and apoptosis. In addition, silencing of circ_0004370 reduced tumor volumes and weights in vivo. We showed that circ_0004370/miR-1301-3p/COL1A1 axis played the critical role in EC to regulate the cell activities. Conclusion Circ_0004370 promotes EC proliferation, migration and invasion, and EMT process and suppresses apoptosis by regulating the miR-1301-3p/COL1A1 axis, indicating that circ_0004370 may be used as a potential therapeutic target for EC.

Abstract
MicroRNAs (miRNAs) can post-transcriptionally regulate the expression of cancer-relevant genes via binding to the 3'-untranslated region (3'-UTR) of the target mRNAs. MiR-133a, as a miRNA, participate in tumorigenesis, progression, autophagy and drug-resistance in various malignancies. Based on the recent insights, we discuss the functions of miR-133a in physiological and pathological processes and its potential effects on cancer diagnosis, prognosis and therapy.

Abstract
Background To undertake a bioinformatics analysis to identify abnormally expressed genes [also referred to as differentially expressed genes (DEGs)] and their functions in esophageal carcinoma (ESCA). Methods DEGs (i.e., GSE100942, GSE17351, GSE26886, and GSE77861) were obtained from a gene expression omnibus database. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses were performed using online tools from the Database for Annotation, Visualization and Integrated Discovery. A protein-protein interaction network was then constructed based on the Search Tool for the Retrieval of Interacting Genes website. Cytoscape software was used to identify the top 20 DEGs located in the central region of the network. For the overall survival analysis, a Kaplan-Meier analysis was conducted of the Gene Expression Profiling Interactive Analysis website, and collagen (COL) 1A2 was selected to detect the molecular mechanism of COL1A2-small interfering ribonucleic acid (siRNA) in the following ESCA cell lines: Eca109 and TE-1. Next, the expression of COL1A2-messanger ribonucleic acid was determined using real-time quantitative polymerase chain reaction. The expression of COL1A2 was also verified by Western blot. Cell proliferation was measured by colony-forming and MTT assays, and migration and invasion by the transwell assay. Results Based on the GEO database and screening out the hub gene, we identified that COL1A2 was abnormally expressed in ESCA. With a series of in vitro experiments, the expression of COL1A2 was defined as higher in Eca109 and TE-1. Conclusions COL1A2 was highly expressed in ESCA tissue samples. Additionally, the proliferation and metastasis of Eca109 and TE-1 cell lines were significantly attenuated by siRNA-COL1A2-mediated small interference. Notably, the expression level of COL1A2 was obviously related to the Akt and epithelial-mesenchymal transition (EMT) pathways.

Abstract
BACKGROUND Hypopharyngeal and esophageal squamous cell carcinoma (ESCC) are the most common double primary tumors with poor prognosis. Intensive work has been made to illuminate the etiology, but the common carcinogenic mechanism remains unclear. Thus, we conducted the study to seek to find the common gene signatures and key functional pathways associated with oncogenesis and treatment in hypopharyngeal squamous cell carcinoma (HSCC) and ESCC by bioinformatic analysis. METHODS Three independent datasets (GSE2379, GSE20347, and GSE75241) were screened out from the Gene Expression Omnibus (GEO) database and the overlapping differentially expressed genes (DEGs) were identified using GEO2R online platform. Subsequently, the Gene Ontology (GO) annotation and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways enrichment analysis of DEGs were conducted using database for annotation, visualization and integrated discovery (DAVID). Meanwhile, the protein-protein interaction network (PPI) constructed by search tool for the retrieval of interacting genes (STRING) was visualized using Cytoscape. Afterwards, the most key module and hub genes were extracted from the PPI network using the Molecular Complex Detection plugin. Moreover, the gene expression profiling interactive analysis (GEPIA) was applied to verify the expression differences and conduct the survival analyses of hub genes. Finally, the interaction network of miRNAs and hub genes constructed by encyclopedia of RNA interactomes (ENCORI) was visualized using Cytoscape. RESULTS A total of 43 DEGs were identified, comprising 25 upregulated genes and 18 downregulated genes, which were mainly involved in the extracellular matrix-receptor interaction, collagen metabolic, epidermis development, cell adhesion, and PI3K/Akt signaling pathways. Subsequently, 12 hub genes were obtained and survival analysis demonstrated SERPINE1 and SPP1 were closely related to poor prognosis of patients with HSCC and ESCC. Finally, hsa-miR-29c-3p, hsa-miR-29a-3p, and hsa-miR-29b-3p were confirmed as the top 3 interactive miRNAs that target the most hub genes according to the interaction network of miRNAs and hub genes. CONCLUSION The common gene signatures and functional pathways identified in the study may contribute to understanding the molecular mechanisms involved in the carcinogenesis and progression of HSCC and ESCC, and provide potential diagnostic and therapeutic targets.

Abstract
Introduction MicroRNAs (miRNAs) are key modulators for gene expression via inducing translational repression or target gene degradation. miR-133a-3p was reported to stimulate or inhibit cancer progression but its role in hepatocellular carcinoma (HCC) remains to be explored. Methods Quantitative real-time PCR (RT-qPCR) was utilized to explore miR-133a-3p expression level in HCC cells. Dual-luciferase activity reporter assay was used to validate the direct interaction between miR-133a-3p and coronin-like actin-binding protein 1C (CORO1C). In addition, we analyzed the expression levels of miR-133a-3p and CORO1C in HCC tissues and normal tissues on the UCALAN website. Functional assays including cell counting kit-8 assay, colony formation assay, flow cytometry analysis and transwell invasion assay were conducted to explore the biological functions of miR-133a-3p in HCC. Results miR-133a-3p was found to have downregulated expression in HCC tissues and cells. Meanwhile, we showed that low miR-133a-3p levels were correlated with poorer overall survival of HCC patients. Overexpression of miR-133a-3p suppressed HCC cell growth and invasion but promoted cell apoptosis via targeting CORO1C. Discussion Our results revealed a novel mechanism of miR-133a-3p in regulating HCC progression and provided evidence that miR-133a-3p functions as a tumor suppressor in HCC.

Abstract
MicroRNAs (miRNAs) are involved in a series of pathology of spinal cord injury (SCI). Although, locally expressed miRNAs have advantages in studying the pathological mechanism, they cannot be used as biomarkers. The "free circulation" miRNAs can be used as biomarkers, but they have low concentration and poor stability in body fluids. Exosomal miRNAs in body fluids have many advantages comparing with free miRNAs. Therefore, we hypothesized that the specific miRNAs in the central nervous system might be transported to the peripheral circulation and concentrated in exosomes after injury. Using next-generation sequencing, miRNA profiles in serum exosomes of sham and subactue SCI rats were analyzed. The results showed that SCI can lead to changes of serum exosomal miRNAs. These changed miRNAs and their associated signaling pathways may explain the pathological mechanism of suacute SCI. More importantly, we found some valuable serum exosomal miRNAs for diagnosis and prognosis of SCI.

Abstract
It is unclear about the functional role of microRNA-133a-3p (miR-133a-3p) in intracranial aneurysm (IA). Hence, the aim of the present study was to investigate the regulatory role of miR-133a-3p on the regulation of vascular endothelial injury-induced IA through phosphoserine aminotransferase 1 (PSAT1)/glycogen synthase kinase 3β (GSK3β)/β-catenin signaling pathway. Normal intracranial arteriole tissues and IA tissues were gathered from patients with brain trauma and IA. The expression of miR-133a-3p, PSAT1, GSK3β, and β-catenin in tissues was determined by RT-qPCR and western blot analysis. The endothelial cells (ECs) of the human IA were cultured and treated with miR-133a-3p mimic and si-PSAT1 to determine their functions in endothelial cell migration, apoptosis, and proliferation. The expression of miR-133a-3p, PSAT1, GSK3β, β-catenin, Ki-67, CyclinD1, Bax, and Bcl-2 in ECs were tested by RT-qPCR or western blot analysis. Moreover, IA rat model was established to detect the pathological changes and the expression of miR-133a-3p, PSAT1, GSK3β, β-catenin, VEGF, and MMP-9 in IA tissues in vivo. Expression of miR-133a-3p was related to the number and size of IA. MiR-133a-3p expression was deceased and the PSAT1, GSK3β, and β-catenin expression was raised in IA. Restored miR-133a-3p and depleted PSAT1 alleviated the pathological change; reduced PSAT1, GSK3β, and β-catenin expression in IA; suppressed apoptosis and advanced proliferation and migration of IA ECs, as well as reduced VEGF and MMP-9 expression in IA tissues in vivo. Our study suggests that overexpression of miR-133a-3p or downregulation of PSAT1 restrains endothelial cell damage and advances endothelial cell proliferation via inhibiting the GSK3β/β-catenin pathway in IA. MiR-133a-3p might be a potential candidate marker and therapeutic target for IA.

Abstract
Background Placenta accreta spectrum (PAS) is a major cause of maternal morbidity and mortality in modern obstetrics, however, few studies have explored the underlying molecular mechanisms and biomarkers. In this study, we aimed to elucidate the regulatory RNA network contributing to PAS, comprising long non-coding (lnc), micro (mi), and messenger (m) RNAs, and identify biomarkers for the prediction of intraoperative blood volume loss. Methods Using RNA sequencing, we compared mRNA, lncRNA, and miRNA expression profiles between five PAS and five normal placental tissues. Furthermore, the miRNA expression profiles in maternal plasma samples from ten PAS and ten control participants were assessed. The data and clinical information were analyzed using R language and GraphPad Prism 7 software. Results Upon comparing PAS and control placentas, we identified 8,806 lncRNAs, 128 miRNAs, and 1,788 mRNAs that were differentially expressed. Based on a lasso regression analysis and correlation predictions, we developed a competing endogenous (ce) RNA network comprising 20 lncRNAs, 4 miRNAs, and 19 mRNAs. This network implicated a reduced angiogenesis pathway in PAS, and correlation analyses indicated that two miRNAs (hsa-miR‐490-3p and hsa-miR-133a-3p) were positively correlated to operation-related blood volume loss. Conclusions We identified a ceRNA regulatory mechanism in PAS, and two miRNAs that may potentially serve as biomarkers of PAS prognosis.

Abstract
Improved prostate cancer prognostic biomarkers are urgently needed. We previously identified the four-miRNA prognostic biomarker panel MiCaP ((miR-23a-3p × miR-10b-5p)/(miR-133a-3p × miR-374b-5p)) for prediction of biochemical recurrence (BCR) after radical prostatectomy (RP). Here, we identified an optimal numerical cut-off for MiCaP dichotomisation using a training cohort of 475 RP patients and tested this in an independent cohort of 281 RP patients (PCA281). Kaplan–Meier, uni- and multivariate Cox regression analyses were conducted for multiple endpoints: BCR, metastatic-(mPC) and castration-resistant prostate cancer (CRPC), prostate cancer-specific (PCSS) and overall survival (OS). Functional effects of the four MiCaP miRNAs were assessed by overexpression and inhibition experiments in prostate cancer cell lines. We found the numerical value 5.709 optimal for MiCaP dichotomisation. This was independently validated in PCA281, where a high MiCaP score significantly [and independent of the Cancer of the Prostate Risk Assessment Postsurgical (CAPRA-S) score] predicted BCR, progression to mPC and CRPC, and PCSS, but not OS. Harrell’s C-index increased upon addition of MiCaP to CAPRA-S for all endpoints. Inhibition of miR-23a-3p and miR-10b-5p, and overexpression of miR-133a-3p and miR-374b-5p significantly reduced cell survival. Our results may promote future implementation of a MiCaP-based test for improved prostate cancer risk stratification.

Abstract
As one of the most aggressive malignancies, osteosarcoma has high risks of death. Although long noncoding RNAs (lncRNAs) may promote the osteosarcoma progression as verified, the potential molecular mechanism of lncRNAs in osteosarcoma remains unknown. Herein, we analyzed lncRNA microarray of osteosarcoma and selected LINC01278 as the study object. Then, we found that the expression of LINC01278 tested by quantitative reverse-transcription polymerase chain reaction was enhanced in tumor tissues compared with the para-carcinoma tissues and related to clinical stage, distant metastasis in osteosarcoma. In addition, the clinical outcomes were poor in osteosarcoma patients with high LINC01278 level. Moreover, LINC01278 promoted proliferation and restrained apoptosis in osteosarcoma cells. Afterward, mechanistic studies turned out that LINC01278 was a competing endogenous RNA of parathyroid hormone type 1 receptor (PTHR1) in osteosarcoma by sponging miR-133a-3p, which was considered as a tumor inhibitor in osteosarcoma. Furthermore, PTHR1 downregulation restored the impacts of inhibited miR-133a-3p on the processes in osteosarcoma cells. Our findings clarified that the carcinogenic effect of LINC01278 in osteosarcoma was mediated through miR-133a-3p/PTHR1 signaling, creating a novel insight into good targets for the therapy and prognosis of osteosarcoma.

Abstract
The present study aimed to investigate the expression of cyclin-dependent kinase 6 (CDK6) and microRNA-126-5p (miR-126-5p) in esophageal cancer tissues and cells, and their effect on esophageal cancer cell proliferation and invasion, and to explore the potential molecular mechanisms. The relative expression levels of CDK6 and miR-126-5p in esophageal cancer tissue, paracancerous tissue, and HEEC and EC109 cells were determined and compared using reverse transcription-quantitative polymerase chain reaction (RT-qPCR). A miR-126-5p overexpression vector was constructed and a stable EC109 cell line expressing miR-126-5p was established. The EC109 cell line was transfected with a CDK6 small interfering RNA sequence. The rate of cell proliferation was determined using the WST-8 method, and cell invasion was determined using a Transwell assay. In addition, the relative expression levels of genes were determined using RT-qPCR; the relative expression levels of proteins were determined by western blot analysis; the binding sites of CDK6 and miR-126-5p were analyzed using TargetScan software; and the interaction of CDK6 and miR-126-5p was verified using dual-fluorescence reporter gene expression. Esophageal tissues and EC109 cells expressed higher levels of CDK6 but significantly lower levels of miR-126-5p compared with adjacent tissues and HEEC cells, and their correlation coefficient between esophageal tissues and matched adjacent tissues was -7.526. The overexpression of miR-126-5p and CDK6 knockdown in the EC109 cell line inhibited cell proliferation and invasion compared with the control and NC (negative control) groups. miR-126-5p overexpression reduced the relative expression level of CDK6, and CDK6 knockdown by siRNA increased the expression of miR-126-5p. miR-126-5p regulated CDK6 expression by binding to the 3'-untranslated region of its mRNA. Overexpression miR-126-5p inhibited the proliferation and migration of esophageal cancer cells by targeting CDK6 and negatively regulating its expression. These findings contribute to the understanding of the underlying molecular mechanism of esophageal cancer.

Abstract
MicroRNAs (miRNAs) are involved in a series of pathology of spinal cord injury (SCI). Although, locally expressed miRNAs have advantages in studying the pathological mechanism, they cannot be used as biomarkers. The "free circulation" miRNAs can be used as biomarkers, but they have low concentration and poor stability in body fluids. Exosomal miRNAs in body fluids have many advantages comparing with free miRNAs. Therefore, we hypothesized that the specific miRNAs in the central nervous system might be transported to the peripheral circulation and concentrated in exosomes after injury. Using next-generation sequencing, miRNA profiles in serum exosomes of sham and subactue SCI rats were analyzed. The results showed that SCI can lead to changes of serum exosomal miRNAs. These changed miRNAs and their associated signaling pathways may explain the pathological mechanism of suacute SCI. More importantly, we found some valuable serum exosomal miRNAs for diagnosis and prognosis of SCI.

Abstract
In this study, we present novel molecular mechanisms by which FOXO1 functions as a tumor suppressor to prevent the pathogenesis of nasopharyngeal carcinoma (NPC). First, we observed that FOXO1 not only controlled tumor stemness and metastasis, but also sensitized NPC cells to cisplatin (DDP) in vitro and in vivo. Mechanistic studies demonstrated that FOXO1-induced miR-200b expression through the GSK3β/β-catenin/TCF4 network-mediated stimulation of ZEB1, which reduced tumor stemness and the epithelial-mesenchymal transition (EMT) signal. Furthermore, we observed FOXO1 interaction with MYH9 and suppression of MYH9 expression by modulating the PI3K/AKT/c-Myc/P53/miR-133a-3p pathway. Decreased MYH9 expression not only reduced its interactions with GSK3β, but also attenuated TRAF6 expression, which then decreased the ubiquitin-mediated degradation of GSK3β protein. Increased GSK3β expression stimulated the β-catenin/TCF4/ZEB1/miR-200b network, which increased the downstream tumor stemness and EMT signals. Subsequently, we observed that chemically synthesized cinobufotalin (CB) strongly increased FOXO1-induced DDP chemosensitivity by reducing MYH9 expression, and the reduction in MYH9 modulated GSK3β/β-catenin and its downstream tumor stemness and EMT signal in NPC. In clinical samples, the combination of low FOXO1 expression and high MYH9 expression indicated the worst overall survival rates. Our studies demonstrated that CB potently induced FOXO1-mediated DDP sensitivity by antagonizing its binding partner MYH9 to modulate tumor stemness in NPC.
