Jacksi M, Schad E, Tantos A. Morphological Changes Induced by TKS4 Deficiency Can Be Reversed by EZH2 Inhibition in Colorectal Carcinoma Cells. Biomolecules 2024; 14:445. [PMID: 38672463 PMCID: PMC11047920 DOI: 10.3390/biom14040445] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2024] [Revised: 03/30/2024] [Accepted: 04/04/2024] [Indexed: 04/28/2024] Open
Abstract
BACKGROUND The scaffold protein tyrosine kinase substrate 4 (TKS4) undergoes tyrosine phosphorylation by the epidermal growth factor receptor (EGFR) pathway via Src kinase. The TKS4 deficiency in humans is responsible for the manifestation of a genetic disorder known as Frank-Ter Haar syndrome (FTHS). Based on our earlier investigation, the absence of TKS4 triggers migration, invasion, and epithelial-mesenchymal transition (EMT)-like phenomena while concurrently suppressing cell proliferation in HCT116 colorectal carcinoma cells. This indicates that TKS4 may play a unique role in the progression of cancer. In this study, we demonstrated that the enhancer of zeste homolog 2 (EZH2) and the histone methyltransferase of polycomb repressive complex 2 (PRC2) are involved in the migration, invasion, and EMT-like changes in TKS4-deficient cells (KO). EZH2 is responsible for the maintenance of the trimethylated lysine 27 on histone H3 (H3K27me3). METHODS We performed transcriptome sequencing, chromatin immunoprecipitation, protein and RNA quantitative studies, cell mobility, invasion, and proliferation studies combined with/without the EZH2 activity inhibitor 3-deazanoplanocine (DZNep). RESULTS We detected an elevation of global H3K27me3 levels in the TKS4 KO cells, which could be reduced with treatment with DZNep, an EZH2 inhibitor. Inhibition of EZH2 activity reversed the phenotypic effects of the knockout of TKS4, reducing the migration speed and wound healing capacity of the cells as well as decreasing the invasion capacity, while the decrease in cell proliferation became stronger. In addition, inhibition of EZH2 activity also reversed most epithelial and mesenchymal markers. We investigated the wider impact of TKS4 deletion on the gene expression profile of colorectal cancer cells using transcriptome sequencing of wild-type and TKS4 knockout cells, particularly before and after treatment with DZNep. Additionally, we observed changes in the expression of several protein-coding genes and long non-coding RNAs that showed a recovery in expression levels following EZH2 inhibition. CONCLUSIONS Our results indicate that the removal of TKS4 causes a notable disruption in the gene expression pattern, leading to the disruption of several signal transduction pathways. Inhibiting the activity of EZH2 can restore most of these transcriptomics and phenotypic effects in colorectal carcinoma cells.

CircRNA-associated ceRNA regulatory networks as emerging mechanisms governing the development and biophysiopathology of epilepsy. CNS Neurosci Ther 2024; 30:e14735. [PMID: 38676299 PMCID: PMC11053249 DOI: 10.1111/cns.14735] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2023] [Revised: 03/17/2024] [Accepted: 04/07/2024] [Indexed: 04/28/2024] Open
Abstract
The etiology of epilepsy is ascribed to the synchronized aberrant neuronal activity within the brain. Circular RNAs (circRNAs), a class of non-coding RNAs characterized by their circular structures and covalent linkage, exert a substantial influence on this phenomenon. CircRNAs possess stereotyped replication, transience, repetitiveness, and paroxysm. Additionally, MicroRNA (miRNA) plays a crucial role in the regulation of diverse pathological processes, including epilepsy. CircRNA is of particular significance due to its ability to function as a competing endogenous RNA, thereby sequestering or inhibiting miRNA activity through binding to target mRNA. Our review primarily concentrates on elucidating the pathological and functional roles, as well as the underlying mechanisms, of circRNA-miRNA-mRNA networks in epilepsy. Additionally, it explores the potential utility of these networks for early detection and therapeutic intervention.

Abstract
The "oxygen effect" improves radiation efficacy; thus, tumor cell oxygen concentration is a crucial factor for improving lung cancer treatment. In the current study, we aimed to identify aerobic exercise-induced changes in oxygen concentrations in non-small cell lung cancer (NSCLC) cells. To this end, an NSCLC xenograft mouse model was established using human A549 cells. Animals were subsequently subjected to aerobic exercise and radiation three times per week for 2 weeks. Aerobic exercise was performed at a speed of 8.0 m/m for 30 min, and the tumor was irradiated with 2 Gy of 6 MV X-rays (total radiation dose 12 Gy). Combined aerobic exercise and radiation reduced NSCLC cell growth. In addition, the positive effect of aerobic exercise on radiation efficacy through oxygenation of tumor cells was confirmed based on hypoxia-inducible factor-1 and carbonic anhydrase IX expression. Finally, whole-transcriptome analysis revealed the key factors that induce oxygenation in NSCLC cells when aerobic exercise was combined with radiation. Taken together, these results indicate that aerobic exercise improves the effectiveness of radiation in the treatment of NSCLC. This preclinical study provides a basis for the clinical application of aerobic exercise to patients with NSCLC undergoing radiation therapy.

Abstract
AIMS We analyzed the differentially expressed proteins (DEPs) in serum and urine in order to provide new potential biomarkers for MM. METHODS Data-Independent Acquisition-based proteomics of serum and urine was performed to identify potential biomarkers for MM patients. Then we performed Western Blotting (WB), ELISA along with their ROC curve analysis to confirm DEPs. RESULTS A total of 1653 proteins in serum and 4519 proteins in urine were identified using Data-Dependent Acquisition method. VCP was the only protein that showed significant differences in different comparison groups in both serum and urine. Pathway analysis revealed that protein processing in the endoplasmic reticulum was the most relevant pathway associated with MM. Furthermore, the increased expression of HSP90B1, VCP, CTSA, HYOU1, PDIA4, and RAB7A was detected by WB. The results of ELISA indicated that a combination of VCP and CTSA provided a high area under curve (AUC) value of 0.883 (95 % CI, 0.769-0.997, p < 0.001) to diagnose NDMM. The combination of VCP, CTSA, ALB, and HGB exhibited better performance (AUC = 0.981), with 100 % specificity and 86.7 % sensitivity. CONCLUSION These findings suggest VCP and CTSA exhibit potential as biomarkers for MM, which may be helpful in the molecular mechanisms and pathogenesis upon further investigation.

Microrna 2024; 13:56-62. [PMID: 38231064 PMCID: PMC11275315 DOI: 10.2174/0122115366266024240101075745] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2023] [Revised: 11/10/2023] [Accepted: 11/16/2023] [Indexed: 01/18/2024]
Abstract
BACKGROUND Colorectal cancer (CRC) is the third most common cancer in the world. Noncoding RNAs or microRNAs (miRNAs; miRs) biomarkers can play a role in cancer carcinogenesis and progression. Specific KRAS and EGFR mutation are associated with CRC development playing a role in controlling the cellular process as epigenetic events. Circulating serum miRs can serve for early diagnosis, monitoring, and prognosis of CRC as biomarkers but it is still unclear, clinically. OBJECTIVE To determine potential biomarkers of circulating serum miR-133b and miR-206 in CRC patients Methods: Bioinformatic prediction of microRNA was screened followed by TargetScanHuman7.2, miRTar2GO, miRDB, MiRanda, and DIANA-microT-CDS. Forty-four CRC serum (19 locally advanced, 23 distant advanced CRC) and 12 normal serum samples were subsequently extracted for RNA isolation, cDNA synthesis, and miR validation. The candidate circulating serum miR-133b and miR-206 were validated resulting in a relative expression via quantitative RT-PCR. Relative expression was normalized to the spike-internal control and compared to normal samples as 1 using the -2ΔΔCt method in principle. RESULTS Our results represented 9 miRs of miR-206, miR-155-5p, miR-143-3p, miR-193a-3p, miR-30a- 5p, miR-30d-5p, miR-30e-5p, miR-543, miR-877-5p relate to KRAS-specific miRs, whereas, 9 miRs of miR-133b, miR-302a-3p, miR-302b-3p, miR-302d-3p, miR-302e, miR-520a-3p, miR-520b, miR-520c- 3p and miR-7-5p relevance to EGFR-specific miRs by using the bioinformatic prediction tools. Our results showed a decreased expression level of circulating serum miR-133b as well as miR-206 associating with CRC patients (local and advanced metastasis) when compared to normal (P < 0.05), significantly. CONCLUSION The circulating serum miR-133b and miR-206 can serve as significant biomarkers for monitoring the clinical outcome of progression with metastatic CRC patients. Increased drug-responsive CRC patients associated with crucial molecular intervention should be further explored, clinically.

Abstract
BACKGROUND MicroRNAs (miRNAs) are widely involved in cell metabolism, and their abnormal expression is involved in the regulation of ovarian cancer development, metastasis, and recurrence. The current study aimed to explore the potential mechanism and prognostic value of miRNAs related to the targeted regulation of oxidized low-density lipoprotein receptor 1 (OLR1) expression in ovarian cancer. METHODS A prospective study was conducted including 132 ovarian cancer patients. Patients were followed up for 36 months. The dual-luciferase reporter gene detection was used to verify the targeting relationship between miRNA and OLR1. Cell Counting Kit-8 assay, flow cytometric analysis, transwell migration, and invasion assays were performed to address the malignant biological behaviors of ovarian cancer cells. RESULTS OLR1 protein and gene expression levels were significantly higher in ovarian cancer tissues and cell lines than in adjacent tissues and normal ovarian epithelial cells. OLR1 depletion facilitated apoptosis and impeded cell proliferation, migration, and invasion in ovarian cancer. Predictive software and dual-luciferase reporter assays showed that miR-106b-5p, miR-93-5p, miR-3129-5p, miR-199b-3p, and miR-4465 targeted OLR1 expression. Functionally, the introduction of miR-106b-5p, miR-93-5p, miR-3129-5p, miR-199b-3p, and miR-4465 mimics abrogated the aggressive phenotype in ovarian cancer cells. Lastly, compared with adjacent tissues, the levels of miR-106b-5p, miR-93-5p, miR-3129-5p, miR-199b-3p, and miR-4465 in cancer tissues were significantly lower (P<0.001). Compared with high miR-106b-5p, high miR-93-5p, high miR-3129-5p, high miR-199b-3p, high miR-4465 group and low OLR1 group, the low miR-106b-5p, low miR-93-5p, low miR-3129-5p, low miR-199b-3p, low miR-4465 group and high OLR1 group have significantly higher recurrence (all P<0.05) and higher mortality (all P<0.05). The identification value of recurrence assessment model [Y = 4.267+0.336*(miR-106b-5p)+0.168*(miR-93-5p)+1.847*(miR-3129-5p)+2.119*(miR-199b-3p)+0.872*(miR-4465)-3.408*(OLR1)] was high with an AUC of 0.918. The prognosis assessment model [Y = 3.914+0.143*(miR-106b-5p)+0.102*(miR-93-5p)+0.115*(miR-3129-5p)+1.369*(miR-199b-3p)+0.186*(miR-4465)-0.334*(OLR1)] also had high identification value with an AUC of 0.934. CONCLUSION The combined detection of miR-106b-5p, miR-93-5p, miR-3129-5p, miR-199b-3p, miR-4465, and OLR1 is expected to become a molecular biomarker for the long-term prognostic assessment of ovarian cancer.

Abstract
Colorectal cancer (CRC) is the most common gastrointestinal tumor worldwide, which is a severe malignant disease that threatens mankind. Cathepsin G (CTSG) has been reported to be associated with tumorigenesis, whereas its role in CRC is still unclear. This investigation aims to determine the function of CTSG in CRC. Our results indicated that CTSG was inhibited in CRC tissues, and patients with CTSG low expression have poor overall survival. Functional experiments revealed that CTSG overexpression suppressed CRC cell progression in vitro and in vivo, whereas CTSG suppression supports CRC development cells in vitro and in vivo. Mechanistically, CTSG overexpression suppressed Akt/mTOR signaling mechanism and elevated apoptotic-associated markers, and CTSG silencing activated Akt/mTOR signaling mechanisms and inhibited apoptotic-associated markers. Furthermore, the Akt suppression signaling pathway by MK2206 abolishes CTSG-silenced expression-induced cell viability and Bcl2 up-regulation in vitro and in vivo. Altogether, these outcomes demonstrate that CTSG may act as a tumor suppressor gene via Akt/mTOR/Bcl2-mediated anti-apoptotic signaling inactivation, and CTSG represents a potential therapeutic target in CRC.

Abstract
Rheumatoid arthritis (RA) is a chronic progressive autoimmune disease of unknown etiology. Human fibroblast-like synoviocytes (HFLSs) are the main effector cells for synovial hyperplasia and invasion in RA. Long non-coding RNAs (lncRNAs) play key roles in several autoimmune diseases, including RA. We investigated the effects of lncRNA HOX transcript antisense intergenic RNA (HOTAIR) on the pathological behavior of HFLSs in RA. The microRNAs (miRNAs) with potential binding sites for lncRNA HOTAIR were predicted using Starbase v2.0. TargetScan (http://www.targetscan.org) was used to analyze the potential target genes of miR-106b-5p. The interactions were further verified using a dual-luciferase reporter assay. RNA and protein expression was determined using quantitative reverse transcription polymerase chain reaction (qRT-PCR) and western blotting. The proliferation, cell invasion and migration, and cell apoptosis of HFLSs in RA was detected by the 3-(4,5-dimethylthiazol)-2,5-diphenyl-tetrazolium bromide (MTT) assay, transwell assay, and flow cytometry (FCM). The dual luciferase reporter assay confirmed the interactions between lncRNA HOTAIR and miR-106b-5p and between miR-106b-5p and SMAD family member 7 (SMAD7). The qRT-PCR results indicated that the expression of lncRNA HOTAIR was markedly decreased and that of miR-106b-5p was markedly increased in HFLSs of RA. Cell proliferation, invasion, and migration of HFLSs were inhibited by lncRNA HOTAIR upregulation, and the expression of miR-106b-5p was negatively regulated by lncRNA HOTAIR in HFLSs. Apoptosis of HFLS cells was improved by the overexpression of lncRNA HOTAIR. All the effects of lncRNA HOTAIR upregulation on HFLSs were reversed after the overexpression of miR-106b-5p. Smad7 was identified as a target gene of miR-106b-5p, and the effects of downregulation of miR-106b-5p on HFLSs could be abolished by silencing Smad7. We found that lncRNA HOTAIR was significantly downregulated in the HFLSs of patients with RA. Moreover, lncRNA HOTAIR influenced cell growth, migration, invasion, and apoptosis in HFLSs through the miR-106b-5p/Smad7 axis.

Abstract
Cathepsin A (CTSA) is overexpressed in various types of cancer and is linked to poor clinical outcomes. However, the clinical application of CTSA in HCC has not been explored. In this study, we examined the protein level of CTSA in the archived HCC samples from 161 patients by Immunohistochemistry (IHC). The high protein level of CTSA was significantly correlated to the poor clinicopathological parameters, such as TNM stage, serum AFP level, tumor differentiation, liver cirrhosis, Child-Pugh class, vascular invasion, tumor encapsulation, tumor recurrence, and patient death. In addition, multivariate Cox regression analysis indicated that high CTSA expression was an independent prognostic factor of OS and RFS. We also analyzed the area under the curve (AUC) of the time-dependent receiver operating characteristic (ROC) of CTSA expression for 1-, 3-, and 5-year OS and RFS prediction. Furthermore, we constructed a nomogram that exhibited excellent prediction performance, which was validated by the calibration curve and decision curve analysis. Together, our study demonstrated that CTSA protein level is strongly associated with poor clinical outcome of HCC patients and may be used as a potential diagnostic and prognostic biomarker in HCC.

Abstract
This study aims to investigate the function and mechanism of microRNA-106b-5p (miR-106b-5p) in cervical cancer (CC). Quantitative reverse transcription-polymerase chain reaction (qRT-PCR) was performed to determine miR-106b-5p expression in CC tissues and normal gastric tissues. Cell counting kit-8 (CCK-8) and colony formation assays were used to analyze the regulatory effects of miR-106b-5p on CC cells' proliferative ability. Wound healing and Transwell assays were conducted to detect the effects of miR-106b-5p on cell migration and invasion. Besides, TargetScan was used to predict the potential target genes of miR-106b-5p. The interaction between miR-106b-5p and fibroblast growth factor 4 (FGF4) was proved by qRT-PCR, Western blot, and dual-luciferase reporter gene assay. MiR-106b-5p expression was down-regulated in CC tissues compared to non-tumorous tissues. The expression of miR-106b-5p was associated with the lymphatic node metastasis, FIGO stage and differentiation of CC. Functional assays revealed that miR-106b-5p overexpression suppressed CC cell proliferation, migration and invasion while miR-106b-5p inhibitor had the opposite effects. In addition, FGF4 was identified as a target gene of miR-106b-5p, and FGF could be negatively regulated by miR-106b-5p. MiR-106b-5p may serve as a tumor suppressor in CC, which can inhibit CC growth and metastasis by down-regulating FGF4 expression.

[PMID: 35317779 PMCID: PMC8941792 DOI: 10.1186/s12885-022-09404-8] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2021] [Accepted: 03/02/2022] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Several studies have documented the key role of microRNAs (miRNAs) in esophageal squamous cell carcinoma (ESCC). Although the expression of the 15-hydroxyprostaglandin dehydrogenase (HPGD) gene and miR-106b-5p are reportedly linked to cancer progression, their underlying mechanisms in ESCC remain unclear. METHODS mRNA and miRNA expression in ESCC tissues and cells were analyzed using RT-qPCR. Luciferase and RNA pull-down assays were used to identify the interaction between miR-106b-5p and HPGD. Xenograft and pulmonary metastasis models were used to assess tumor growth and metastasis. CCK-8, BrdU, colony formation, adhesion, cell wound healing, Transwell, and caspase-3/7 activity assays, and flow cytometry and western blot analyses were used to examine the function of miR-106-5p and HPGD in ESCC cell lines. RESULTS The findings revealed that miR-106b-5p expression was upregulated in ESCC tissues and cell lines. miR-106b-5p augmented cellular proliferation, colony formation, adhesion, migration, invasion, and proportion of cells in the S-phase, but reduced apoptosis and the proportion of cells in G1-phase. Silencing of miR-106-5p inhibited tumor growth in vivo and pulmonary metastasis. Although HPGD overexpression suppressed proliferation, colony formation, adhesion, migration, and invasion of ESCC cells, it promoted apoptosis and caused cell cycle arrest of the ESCC cells. The results also indicated a direct interaction of HPGD with miR-106b-5p in ESCC cells. Furthermore, miR-106b-5p inhibited HPGD expression, thereby suppressing ESCC tumorigenesis. CONCLUSION Our data suggest that miR-106b-5p enhances proliferation, colony formation, adhesion, migration, and invasion, and induces the cycle progression, but represses apoptosis of ESCC cells by targeting HPGD. This suggests that the miR-106b-5p/HPGD axis may serve as a promising target for the diagnosis and treatment of ESCC.

Abstract
The objective of this study was to investigate modulatory mechanism of miR-106b-5p and tissue inhibitor of metalloproteinases 2 (TIMP2) on cervical squamous cell carcinoma cells. Differentially expressed genes in CSCC were analyzed via bioinformatics analysis. The targeting impact of miR-106b-5p on TIMP2 was validated through dual-luciferase assay and RNA immunoprecipitation assay. MiR-106b-5p level and TIMP2 mRNA level were assessed via qRT-PCR. TIMP2 protein level was measured via western blot. Malignant behaviors of CSCC cells were evaluated by functional experiments. The EMT and apoptosis-related proteins were determined via western blot. MiR-106b-5p was noticeably elevated in CSCC cells. Its downstream target was TIMP2. MiR-106b-5p and TIMP2 levels were inversely correlated. MiR-106b-5p overexpression fostered malignant phenotypes of CSCC cells, and vice versus. TIMP2 overexpression weakened the promotive impact of forced expression of miR-106b-5p on CSCC cell growth. EMT was facilitated by forced expression of miR-106b-5p. MiR-106b-5p regulates the progression of CSCC cells via targeting TIMP2, which may provide novel value for development of therapeutic targets for CSCC.

Abstract
OBJECTIVE Parkinson's disease (PD) is a neurodegenerative disease caused by the loss of dopaminergic neurons. Here, we aimed to explore the function of LncRNA PART1 in PD and its underlying mechanisms. METHODS An in vivo MPTP-induced mouse model of PD was generated and the SH-SY5Y cells were treated with MPP+ to induce neuronal damage in vitro. The expressions of LncRNA PART1 and microRNA-106b-5p were assessed by RT-qPCR. The level of caspase 3 protein was detected by western blot. CCK8 assay and Annexin V/PI staining were used for detecting cell viability and survival rate, respectively. The interactions between microRNA-106b-5p and LncRNA PART1 or MCL1 were determined by RNA pull-down assay, RIP assay and DLR assay. The levels of inflammatory cytokines were assessed by ELISA, and the levels of LDH, ROS or SOD were verified using the appropriate assay kits. RESULTS The expression of LncRNA PART1 was decreased in PD model in vivo and in vitro (all P<0.05). In SH-SY5Y cells treated with MPP+, the overexpression of LncRNA PART1 increased cell viability and reduced cell apoptosis, the secretion of inflammatory cytokines and oxidative stress reaction (all P<0.05). Furthermore, LncRNA PART1 sponged microRNA-106b-5p which directly targeted MCL1 and thus regulated the expression of MCL1. LncRNA PART1 attenuated the injury of SH-SY5Y cells induced by MPP+ via targeting microRNA-106b-5p and enhancing MCL1 expression. CONCLUSION LncRNA PART1 could alleviate the damage effects of MPP+ on SH-SY5Y cells by regulating microRNA-106b-5p/MCL1 axis, suggesting the potential therapeutic value of LncRNA PART1 as a target in PD.

Abstract
OBJECTIVE The aim of this study was to investigate the role and molecular regulatory mechanisms of baicalin in oral squamous cell carcinoma (OSCC) progression. DESIGN Gene expression in OSCC cells was detected by quantitative reverse transcription polymerase chain reaction (RT-qPCR). OSCC cell viability, migration, invasion and stemness were measured by 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), 5-ethynyl-2'-deoxyuridine (EdU), wound healing, Transwell, and sphere formation assays. The target genes of miR-106b-5p were predicted using bioinformatic tools. The interaction between microRNA-miR-106b-5p (miR-106b-5p) and disabled homolog 2 (DAB2) was confirmed by a luciferase reporter assay. TOP/FOP-Flash reporter assay and western blot analysis were used to analyze the activity of the Wnt/β-catenin pathway. RESULTS Baicalin inhibited OSCC cell viability, migration, invasion, and stemness. Baicalin downregulated miR-106b-5p expression. In addition, MiR-106b-5p upregulation reversed the effects of baicalin on OSCC cells. As a target gene of miR-106b-5p, DAB2 was negatively regulated by miR-106b-5p and upregulated by baicalin in OSCC cells. MiR-106b-5p activated Wnt/β-catenin pathway in OSCC cells by inhibiting DAB2. Baicalin suppressed Wnt/β-catenin pathway by upregulating DAB2. In rescue assays, miR-106b-5p overexpression-induced promotion of OSCC cellular processes was attenuated by DAB2 upregulation. CONCLUSIONS Baicalin exerts anti-tumor effects in OSCC by inhibiting the miR-106b-5p-Wnt/β-catenin pathway via upregulating DAB2.

Abstract
In this study, we investigated the mechanistic role and prognostic significance of IGSF10 in lung adenocarcinoma. Oncomine database analysis showed that IGSF10 expression was significantly reduced in most cancer types, including lung adenocarcinoma (LUAD). In the TCGA-LUAD dataset, IGSF10 expression correlated positively with proportions of tumor-infiltrated B cells, CD4+ T cells, CD8+ T cells, neutrophils, macrophages, and dendritic cells. Kaplan-Meier survival analysis showed that overall survival of patients with low IGSF10 expression was significantly shorter than those with high IGSF10 expression. MiRWalk2.0 database analysis and dual luciferase reporter assays confirmed that miR-106b-5p suppressed IGSF10 expression by binding to its 3’UTR. MiR-106b-5p levels inversely correlated with IGSF10 expression in the TCGA-LUAD dataset. Moreover, inhibition of miR-106b-5p significantly decreased in vitro proliferation, migration, and invasion by LUAD cells, whereas miR-106b-5p overexpression reversed those effects. These results demonstrate that IGSF10 is an independent prognostic factor for LUAD. Furthermore, miR-106b-5p suppressed IGSF10 expression in LUAD tissues by binding to its 3’UTR, which makes IGSF10 and miR-106b-5p potential prognostic biomarkers and therapeutic targets in LUAD patients.

Abstract
Cathepsin A (CTSA) is a lysosomal protease that regulates galactoside metabolism. The previous study has shown CTSA is abnormally expressed in various types of cancer. However, rarely the previous study has addressed the role of CTSA in hepatocellular carcinoma (HCC) and its prognostic value. To study the clinical value and potential function of CTSA in HCC, datasets from the Cancer Genome Atlas (TCGA) database and a 136 HCC patient cohort were analyzed. CTSA expression was found to be significantly higher in HCC patients compared with normal liver tissues, which was supported by immunohistochemistry (IHC) validation. Both gene ontology (GO) and The Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses demonstrated that CTSA co-expressed genes were involved in ATP hydrolysis coupled proton transport, carbohydrate metabolic process, lysosome organization, oxidative phosphorylation, other glycan degradation, etc. Survival analysis showed a significant reduction both in overall survival (OS) and recurrence-free survival (RFS) of patients with high CTSA expression from both the TCGA HCC cohort and 136 patients with the HCC cohort. Furthermore, CTSA overexpression has diagnostic value in distinguishing between HCC and normal liver tissue [Area under curve (AUC) = 0.864]. Moreover, Gene set enrichment analysis (GSEA) showed that CTSA expression correlated with the oxidative phosphorylation, proteasome, and lysosome, etc. in HCC tissues. These findings demonstrate that CTSA may as a potential diagnostic and prognostic biomarker in HCC.

Abstract
BACKGROUND Long non-coding RNA (lncNRA) forkhead box D3 antisense RNA 1 (FOXD3-AS1) has been proved to promote or suppress the occurrence and development of multiple types of human tumors. However, the function and mechanism of FOXD3-AS1 in non-small cell lung cancer (NSCLC) are scarcely understood. METHODS qRT-PCR was used for detecting FOXD3-AS1, miR-150 and SRC kinase signaling inhibitor 1 (SRCIN1) mRNA expression in NSCLC tissues, and the relationship between pathological characteristics of NSCLC patients and FOXD3-AS1 expression level was analyzed. With human NSCLC cell lines H1299 and A549 as cell models, CCK-8 and BrdU assays were employed for detecting cancer cell proliferation, and Transwell assay was employed for detecting cell invasion ability. Dual luciferase reporter gene assay and RNA immunoprecipitation (RIP) assay were used for the verification of the targeting relationshipe between FOXD3-AS1 and miR-150, and Western blot was employed for detecting SRCIN1 protein expression. RESULTS FOXD3-AS1 expression was significantly reduced in NSCLC tissues and cell lines, and low expression of FOXD3-AS1 was closely related to positive lymph node metastasis and relatively high tumor grade. FOXD3-AS1 over-expression inhibited the proliferation and invasion of H1299 cell lines, while its knockdown promoted the proliferation and invasion of A549 cells. Additionally, it was confirmed that FOXD3-AS1 suppressed the expression of miR-150 by targeting it, and up-regulated the expression of SRCIN1. CONCLUSIONS FOXD3-AS1 indirectly enhances the expression of SRCIN1 by targeting miR-150, thereby inhibiting NSCLC progression.

Abstract
Osteoarthritis (OA) is a common degenerative joint disease that affects people worldwide. The interaction between fibroblast-like synoviocytes (FLSs) and chondrocytes may play a vital role in OA disease pathology. However, the underlying mechanisms by which FLSs exert regulatory effects on chondrocytes still need to be elucidated. Exosomes, small membrane vesicles secreted from living cells, are known to play a variety of roles in mediating cell-to-cell communication through the transferring of biological components such as non-coding RNAs and proteins. Here, we investigate the cellular processes of chondrocytes regulated by FLS-derived exosomes and the mechanisms of action underlying the functions of exosomes in OA pathogenesis. We observed that exosome-mediated cartilage repair was characterized by increased cell viability and migration as well as alleviated matrix degradation. Using chondrocyte cultures, the enhanced cellular proliferation and migration during exosome-mediated cartilage repair was linked to the exosomal lncRNA H19-mediated regulation of the miR-106b-5p/TIMP2 axis. Transfection of miR-106-5p mimics in chondrocytes significantly decreased cell proliferation and migration, promoted matrix degradation characterized by elevated MMP13 and ADAMTS5 expression, and reduced the expression of COL2A1 and ACAN in chondrocytes. Furthermore, we found that TIMP2 was directly regulated by miR-106-5p. Co-transfections of miR-106-5p mimics and TIMP2 resulted in higher levels of COL2A1 and ACAN, but lower levels of MMP13 and ADAMTS5. Together, these observations demonstrated that the lncRNA H19 may promote chondrocyte proliferation and migration and inhibit matrix degradation in OA possibly by targeting the miR-106b-5p/TIMP2 axis. In the future, H19 may serve as a potential therapeutic target for the treatment of OA.

Abstract
Long known as digestive organelles, lysosomes have now emerged as multifaceted centers responsible for degradation, nutrient sensing, and immunity. Growing evidence also implicates role of lysosome-related mechanisms in pathologic process. In this review, we discuss physiological function of lysosomes and, more importantly, how the homeostasis of lysosomes is disrupted in several diseases, including atherosclerosis, neurodegenerative diseases, autoimmune disorders, pancreatitis, lysosomal storage disorders, and malignant tumors. In atherosclerosis and Gaucher disease, dysfunction of lysosomes changes cytokine secretion from macrophages, partially through inflammasome activation. In neurodegenerative diseases, defect autophagy facilitates accumulation of toxic protein and dysfunctional organelles leading to neuron death. Lysosomal dysfunction has been demonstrated in pathology of pancreatitis. Abnormal autophagy activation or inhibition has been revealed in autoimmune disorders. In tumor microenvironment, malignant phenotypes, including tumorigenesis, growth regulation, invasion, drug resistance, and radiotherapy resistance, of tumor cells and behaviors of tumor-associated macrophages, fibroblasts, dendritic cells, and T cells are also mediated by lysosomes. Based on these findings, a series of therapeutic methods targeting lysosomal proteins and processes have been developed from bench to bedside. In a word, present researches corroborate lysosomes to be pivotal organelles for understanding pathology of atherosclerosis, neurodegenerative diseases, autoimmune disorders, pancreatitis, and lysosomal storage disorders, and malignant tumors and developing novel therapeutic strategies.

Abstract
Intriguingly, microRNAs (miRs) transferred as cargo in extracellular vesicles (EVs) can modulate wound healing through their regulation of fibroblast functions. In this study, we investigated the effects of miR‐106b transfer via EVs derived from human umbilical vein endothelial cells (HUVECs) on skin wound healing. Dual‐luciferase reporter gene assay identified that miR‐106b could target and inhibit JMJD3. RT‐qPCR analysis showed EVs isolated from HUVECs had enriched expression of miR‐106b. LL29 fibroblast cells and HaCaT keratinocytes were co‐cultured with HUVEC‐derived EVs, in which miR‐106b had been up‐regulated or down‐regulated by its mimic or inhibitor. The co‐culture with HUVEC‐derived EVs increased miR‐106b expression, and reduced the viability and adhesion of LL29 and HaCaT cells, whereas the inhibition of miR‐106b in HUVEC‐derived EVs enhanced the viability and adhesion of LL29 and HaCaT cells through up‐regulation of JMJD3. Next, we showed that JMJD3 overexpression enhanced LL29 and HaCaT cell viability and adhesion through elevating RIPK3, which induced the phosphorylation of AKT during the wound‐healing process. We next developed a mouse skin wound model to investigate the actions of miR‐106b in vivo after 14 days. The delivery of miR‐106b via HUVEC‐derived EVs delayed wound healing through suppression of collagen I content and angiogenesis, but had no effects on pro‐inflammatory cytokines. In conclusion, miR‐106b from HUVEC‐derived EVs inhibits JMJD3 and RIPK3, leading to the inhibition of skin wound healing, thus constituting a new therapeutic target.

Abstract
Although a certain proportion of intramucosal carcinomas (IMCs) of the stomach does metastasize, the majority of patients are currently treated with endoscopic resection without lymph node dissection, and this potentially veils any existing metastasis and may put some patients in danger. In this regard, biological markers from the resected IMC that can predict metastasis are warranted. Here, we discovered unique miRNA expression profiles that consist of 21 distinct miRNAs that are specifically upregulated (miR-628-5p, miR-1587, miR-3175, miR-3620-5p, miR-4459, miR-4505, miR-4507, miR-4720-5p, miR-4742-5p, and miR-6779-5p) or downregulated (miR-106b-3p, miR-125a-5p, miR-151b, miR-181d-5p, miR-486-5p, miR-500a-3p, miR-502-3p, miR-1231, miR-3609, and miR-6831-5p) in metastatic (M)-IMC compared to nonmetastatic (N)-IMC, or nonneoplastic gastric mucosa. Intriguingly, most of these selected miRNAs showed stepwise increased or decreased expression from nonneoplastic tissue to N-IMC to M-IMC. This suggests that common oncogenic mechanisms are gradually intensified during the metastatic process. Using a machine-learning algorithm, we demonstrated that such miRNA signatures could distinguish M-IMC from N-IMC. Gene ontology and pathway analysis revealed that TGF-β signaling was enriched from upregulated miRNAs, whereas E2F targets, apoptosis-related, hypoxia-related, and PI3K/AKT/mTOR signaling pathways, were enriched from downregulated miRNAs. Immunohistochemical staining of samples from multiple institutions indicated that PI3K/AKT/mTOR pathway components, MAPK1, phospho-p44/42 MAPK, and pS6 were highly expressed and the expression of SMAD7, a TGF-β pathway component, was decreased in M-IMC, which could aid in distinguishing M-IMC from N-IMC. The miRNA signature discovered in this study is a valuable biological marker for identifying metastatic potential of IMCs, and provides novel insights regarding the metastatic progression of IMC.

Abstract
Cancer is a global health concern, and the prognosis of patients with cancer is associated with metastasis. Multistep processes are involved in cancer metastasis. Accumulating evidence has shown that cancer cells acquire the capacity of anoikis resistance and anchorage-independent cell growth, which are critical prerequisite features of metastatic cancer cells. Multiple cellular factors and events, such as apoptosis, survival factors, cell cycle, EMT, stemness, autophagy, and integrins influence the anoikis resistance and anchorage-independent cell growth in cancer. Noncoding RNAs (ncRNAs), such as microRNAs (miRNAs) and long noncoding RNAs (lncRNAs), are dysregulated in cancer. They regulate cellular signaling pathways and events, eventually contributing to cancer aggressiveness. This review presents the role of miRNAs and lncRNAs in modulating anoikis resistance and anchorage-independent cell growth. We also discuss the feasibility of ncRNA-based therapy and the natural features of ncRNAs that need to be contemplated for more beneficial therapeutic strategies against cancer.

Renin angiotensin system genes are biomarkers for personalized treatment of acute myeloid leukemia with Doxorubicin as well as etoposide. PLoS One 2020; 15:e0242497.

Abstract
Despite the availability of various treatment protocols, response to therapy in patients with Acute Myeloid Leukemia (AML) remains largely unpredictable. Transcriptomic profiling studies have thus far revealed the presence of molecular subtypes of AML that are not accounted for by standard clinical parameters or by routinely used biomarkers. Such molecular subtypes of AML are predicted to vary in response to chemotherapy or targeted therapy. The Renin-Angiotensin System (RAS) is an important group of proteins that play a critical role in regulating blood pressure, vascular resistance and fluid/electrolyte balance. RAS pathway genes are also known to be present locally in tissues such as the bone marrow, where they play an important role in leukemic hematopoiesis. In this study, we asked if the RAS genes could be utilized to predict drug responses in patients with AML. We show that the combined in silico analysis of up to five RAS genes can reliably predict sensitivity to Doxorubicin as well as Etoposide in AML. The same genes could also predict sensitivity to Doxorubicin when tested in vitro. Additionally, gene set enrichment analysis revealed enrichment of TNF-alpha and type-I IFN response genes among sensitive, and TGF-beta and fibronectin related genes in resistant cancer cells. However, this does not seem to reflect an epithelial to mesenchymal transition per se. We also identified that RAS genes can stratify patients with AML into subtypes with distinct prognosis. Together, our results demonstrate that genes present in RAS are biomarkers for drug sensitivity and the prognostication of AML.

Abstract
Simple Summary This article describes an emerging area of significant interest in cancer and cell death and the relationships shared by these through the transcriptional regulation of cathepsin protease genes by micro-RNAs that are connected to p53 activation. While it has been demonstrated that the p53 protein can directly regulate some cathepsin genes and the expression of their upstream regulatory micro-RNAs, very little is known about what input the p53 isoform proteins may have in regulating this relationship. Herein, we draw attention to this important regulatory aspect in the context of describing mechanisms that are being established for the micro-RNA regulation of cathepsin protease genes and their collective use in diagnostic or prognostic assays. Abstract As the direct regulatory role of p53 and some of its isoform proteins are becoming established in modulating gene expression in cancer research, another aspect of this mode of gene regulation that has captured significant interest over the years is the mechanistic interplay between p53 and micro-RNA transcriptional regulation. The input of this into modulating gene expression for some of the cathepsin family members has been viewed as carrying noticeable importance based on their biological effects during normal cellular homeostasis and cancer progression. While this area is still in its infancy in relation to general cathepsin gene regulation, we review the current p53-regulated micro-RNAs that are generating significant interest through their regulation of cathepsin proteases, thereby strengthening the link between activated p53 forms and cathepsin gene regulation. Additionally, we extend our understanding of this developing relationship to how such micro-RNAs are being utilized as diagnostic or prognostic tools and highlight their future uses in conjunction with cathepsin gene expression as potential biomarkers within a clinical setting.

Abstract
Temporal lobe epilepsy (TLE) is common intractable epilepsy that affects the patient's lives. The circular RNA circ_ANKMY2 (circ_ANKMY2) has been reported to be abnormally expressed in TLE. Nevertheless, the role and mechanism of circ_ANKMY2 in TLE are unclear. A human neuroblastoma cell line (SK-N-AS) was used for a series of studies. Expression levels of circ_ANKMY2, miR-106b-5p, and Forkhead Box Protein 1 (FOXP1) mRNA in TLE tissues were assessed through quantitative real-time polymerase chain reaction (qRT-PCR). Cell colony formation, proliferation, and apoptosis were determined by cell colony formation, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), or flow cytometry assays. The levels of FOXP1 protein, Ki67, B cell lymphoma (Bcl-2), Bcl-2 Associated X (Bax), and Cleaved caspase-3 were evaluated by western blot analysis. The relationship between circ_ANKMY2 or FOXP1 and miR-106b-5p was verified with dual-luciferase reporter assay. We observed that circ_ANKMY2 and FOXP1 expression were reduced while miR-106b-5p expression was increased in TLE tissues. Overexpression of circ_ANKMY2 decreased spontaneous recurrent seizures (SRSs) in rat TLE model and blocked cell colony formation, proliferation, and induced cell apoptosis in SK-N-AS cells. Importantly, circ_ANKMY2 was verified as a sponge for miR-106b-5p. In addition, miR-106b-5p mimics abolished circ_ANKMY2 elevation-mediated effects on colony formation, proliferation, and apoptosis of SK-N-AS cells. Also, FOXP1 served as a target for miR-106b-5p. And FOXP1 silencing overturned the effects of miR-106b-5p inhibitors on the colony formation, proliferation, and apoptosis of SK-N-AS cells. In sum, circ_ANKMY2 modulated TLE advancement via regulation of FOXP1 expression through sponging miR-106b-5p, and circ_ANKMY2 might be an underlying target for the improvement of TLE.

Abstract
The function of microRNAs (miRs) is associated with the development and progression of various malignancies, with miRs presenting stably in the serum. The current study assessed the role of miR-1246 and miR-106b in the serum of patients with esophageal squamous cell carcinoma (ESCC). A comprehensive microarray analysis of miR expression was performed using the serum of patients with ESCC, which were subsequently validated via reverse transcription-quantitative PCR. A total of 55 test samples were obtained from Chiba University and 101 validation samples were gained from Chiba Cancer Center. The results revealed that miR-1246 expression significantly increased and miR-106b expression significantly decreased in each cohort. Receiver operating characteristic analysis revealed that the area under the curve (AUC) value of miR-1246 was 0.816 (sensitivity, 72.7%; specificity, 69.2%) and 0.779 (sensitivity, 71.3%; specificity, 70.6%) for the test and validation cohorts, respectively. The AUC of miR-106b was 0.716 (sensitivity, 65.5%; specificity, 61.6%) and 0.815 (sensitivity, 74.3%; specificity, 73.5%), respectively. In addition, the AUC of the miR-1246/miR-106b ratio was 0.901 (sensitivity, 80.0%; specificity, 80.0%) and 0.903 (sensitivity, 82.1%; specificity, 82.3%), respectively, which indicated a higher diagnostic ability compared with that of miR-1246 or miR-106b alone. The high miR-1246/miR-106b ratio group was associated with clinicopathological factors such as depth of invasion, progression, lymph node metastasis, and poor prognosis. Therefore, effective biomarkers may be generated by combining individual miRs obtained by comprehensive analysis of ESCC patient sera.

Abstract
Chronic myeloid leukemia (CML) results from a translocation between chromosomes 9 and 22, which generates the Philadelphia chromosome. This forms BCR/ABL1, an active tyrosine kinase protein that promotes cell growth and replication. Despite great progress in CML treatment in the form of tyrosine kinase inhibitors, allogeneic-hematopoietic stem cell transplantation (allo-HSCT) is currently used as an important treatment alternative for patients resistant to these inhibitors. Studies have shown that unregulated expression of microRNAs, which act as oncogenes or tumor suppressors, is associated with human cancers. This contributes to tumor formation and development by stimulating proliferation, angiogenesis, and invasion. Research has demonstrated the potential of microRNAs as biomarkers for cancer diagnosis, prognosis, and therapeutic targets. In the present study, we compared the circulating microRNA expression profiles of 14 newly diagnosed patients with chronic phase-CML and 14 Philadelphia chromosome-negative patients after allo-HSCT. For each patient, we tested 758 microRNAs by reverse transcription quantitative polymerase chain reaction (RT-qPCR) analysis. The global expression profile of microRNAs revealed 16 upregulated and 30 downregulated microRNAs. Target genes were analyzed, and key pathways were extracted and compared. Bioinformatics tools were used to analyze data. Among the downregulated miRNA target genes, some genes related to cell proliferation pathways were identified. These results reveal the comprehensive microRNA profile of CML patients and the main pathways related to the target genes of these miRNAs in cytogenetic remission after allo-HSCT. These results provide new resources for exploring stem cell transplantation-based CML treatment strategies.

[PMID: 33061574 PMCID: PMC7520100 DOI: 10.2147/cmar.s260537] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2020] [Accepted: 08/07/2020] [Indexed: 12/11/2022] Open
Abstract
Purpose Long non-coding RNA plasmacytoma variant translocation 1 (PVT1) has been revealed to involve in the progression of CRC. However, the precise mechanisms of PVT1 in action remain unclear. Methods The expression of PVT1, microRNA-106b-5p (miR-106b-5p) and four jointed box 1 (FJX1) was measured using quantitative real-time polymerase chain reaction (qRT-PCR) or Western blot, respectively. Cell proliferation was investigated by 3-(4,5)-dimethylthiahiazo (−z-y1)-3,5-di-phenytetrazoliumromide assay. Transwell assay was used to determine cell migration and invasion. The correlation between miR-106b-5p and PVT1 or FJX1 was confirmed using luciferase reporter assay. The effects of PVT1 in vivo were assessed using mice xenograft model. Results PVT1 was up-regulated in CRC tissues and cell lines, especially in CRC tissues with high-grade, and highly expressed PVT1 predicted worse prognosis. Functional experiments demonstrated that PVT1 deletion inhibited CRC cell proliferation, migration and invasion in vitro and suppressed tumor growth in vivo. MiR-106b-5p was confirmed to be a target of PVT1, and inhibition of miR-106b-5p reversed the inhibitory effects of PVT1 knockdown on CRC cell malignant phenotypes. In addition, we found miR-106b-5p directly targeted FJX1, and miR-106b-5p-mediated inhibition on CRC cell proliferation, migration and invasion was attenuated by FJX1 up-regulation. Importantly, it was also proved that PVT1 could indirectly regulate FJX1 expression via targeting miR-106b-5p. Conclusion Knockdown of PVT1 impaired cell proliferation, migration and invasion in CRCs via regulating miR-106b-5p/FJX1 axis, which provided a novel insight into the development of therapeutic strategies for CRC patients.

Circular noncoding RNA circMBOAT2 is a novel tumor marker and regulates proliferation/migration by sponging miR-519d-3p in colorectal cancer. Cell Death Dis 2020; 11:625.

Abstract
Colorectal cancer (CRC) is a common malignant tumor with a poor prognosis. However, its pathogenesis has not been fully elucidated, accounting for poor overall survival. Circular RNA (circRNA) is a class of noncoding RNAs discovered many years ago. Only recently have they been re-evaluated for their important roles in the regulation of gene expression. Studies have confirmed that circRNAs have important biological functions in a variety of malignant tumors. This study aimed to characterize one circRNA derived from the MBOAT2 gene and termed it circMBOAT2, which has been reported to promote prostate cancer progression. CircMBOAT2 is highly expressed in both CRC tissues and serum samples, and has a correlation with tumor stage. The receiver-operating characteristic curves suggested that circMBOAT2 acted as a novel diagnostic tumor marker in CRC. Univariate and multivariate analyses showed that the levels of circMBOAT2 in tissues were independent prognostic markers of CRC. Further functional studies revealed that circMBOAT2 served as a microRNA (miRNA) sponge of miR-519d-3p and promoted the proliferation, migration, and invasion of CRC cells. Also, circMBOAT2 regulated cell proliferation and migration by competitively binding to miR-519d-3p and targeting troponin-associated protein (TROAP) in CRC cells. These results suggested that circMBOAT2 might be a novel potential biomarker of CRC.

Abstract
MicroRNAs (miRNAs), as a class of small, well-conserved, non-coding RNA molecules, hold the capacity to post-transcriptionally suppress the expression of over 50% protein-coding genes. Emerging and accumulating evidence suggests that miRNAs function as the master regulators of multiple pathophysiological processes, and play important roles in diverse human diseases, especially in tumorigenesis and progression. MiR-106b-5p, a member of miR-106b seed family, has been demonstrated to be aberrantly expressed in human solid malignancies, and to play paradoxically opposing functions as an oncomiR or a tumor suppressor in tumor development. In addition, it has been recently reported to be a promising biomarker for prognostic evaluation for cancer patients. In the present review, we provided an overview to summarize the present findings of miR-106b-5p in cancer research fields, thereby establishing comprehensive understanding of its diverse functions and clinical implications in human cancers.

Abstract
Cathepsin A (CTSA) is a lysosomal protease that is abnormally expressed in various types of cancer; however, the function of CTSA in lung adenocarcinoma (LUAD) is unknown. The aim of the present study was to investigate the role of CTSA during LUAD development in vitro. The Cancer Genome Atlas (TCGA) database was used to analyze the expression of CTSA mRNA in LUAD tissues. CTSA was significantly upregulated in LUAD tissues compared with normal lung tissues. To explore the effect of CTSA on LUAD in vitro, LUAD A549 cells were transfected with CTSA small interfering RNA and the hallmarks of tumorigenesis were investigated using cell proliferation, cell cycle, wound healing, invasion and western blot assays. Following CTSA knockdown, proliferation of LUAD cells was decreased and an increased proportion of LUAD cells were arrested at the G0/G1 phase, with altered expression of critical cell cycle and proliferative marker proteins, including p53, p21 and proliferating cell nuclear antigen. Moreover, CTSA knockdown decreased the migration and invasion of A549 cells, as determined by wound healing, invasion, and western blotting assays. The expression levels of key proteins involved in epithelial-mesenchymal transition were analyzed by western blotting. CTSA knockdown enhanced the expression of E-cadherin, but decreased the expression of N-cadherin and β-catenin in A549 cells. To the best of our knowledge, the present study suggested for the first time it has been identified that CTSA may serve as a tumor promoter in LUAD, enhancing the malignant progression of LUAD cells by promoting cell proliferation, migration and invasion. The results suggested that CTSA may serve as a novel therapeutic target for LUAD.

Abstract
Noncoding RNAs (ncRNAs), especially microRNA (miRNA) and long noncoding RNA (lncRNA), have an impact on a variety of important biological processes during colon adenocarcinoma (COAD) progression. This includes chromatin organization, transcriptional and posttranscriptional regulation, and cell-cell signaling. The aim of this study is to identify the ncRNA-regulated modules that accompany the progression of COAD and to analyze their mechanisms, in order to screen the potential prognostic biomarkers for COAD. An integrative molecular analysis was carried out to identify the crosstalks of gene modules between different COAD stages, as well as the essential ncRNAs in the posttranscriptional regulation of these modules. 31 ncRNA regulatory modules were found to be significantly associated with overall survival in COAD patients. 17 out of the 31 modules (in which ncRNAs played essential roles) had improved the predictive ability for COAD patient survival compared to only the mRNAs of those modules, which were enriched in the core cancer hallmark pathways with closer interactions. These suggest that the ncRNAs' regulatory modules not only exhibit close relation to COAD progression but also reflect the dynamic significant crosstalk of genes in the modules to the different malignant extent of COAD.

Abstract
Acute pulmonary embolism (APE) is a common cause of acute cardiovascular failure and has a high morbidity and mortality rate. Inhibiting the excessive proliferation and migration of pulmonary artery smooth muscle cells (PASMCs) is a potential treatment strategy following an APE. Various microRNAs (miRNAs/miRs) have been shown to regulate cell proliferation, apoptosis and other physiological processes. However, the specific mechanisms underlying the action of multiple miRNAs are still not understood in APE. In the present study, the role of miR‑106b‑5p on APE was demonstrated in platelet‑derived growth factor (PDGF)‑induced PASMCs in vitro and in an APE‑mouse model in vivo. The results showed that miR‑106b‑5p expression was downregulated in PDGF‑induced PASMCs and APE mice, and NOR1 levels were upregulated. Proliferating cell nuclear antigen (PCNA) expression levels in cells and proliferation of PASMCs proliferation and migration were reduced following treatment with miR‑106b‑5p agomiR, and increased following treatment with miR‑106b‑5p antagomiR. miR‑106b‑5p targeted the 3' untranslated region of NOR‑1 mRNA and reduced NOR1 expression. NOR1 overexpression reversed the effects of miR‑106‑5p on PDGF‑induced PASMCs. The functional roles of miR‑106b‑5p in PDGF‑induced PASMCs and an APE mouse‑model, and the underlying molecular mechanisms were evaluated. AgomiR‑106b‑5p improved APE‑induced mortality and pulmonary vascular proliferation in mice. These data suggest that miR‑106‑5p is a novel regulator of proliferation of PASMCs and of pulmonary vascular remodeling through PDGF‑induced PASMCs in an APE mouse model via targeting NOR1. These results expand the understanding of the pathogenesis underlying APE and highlight potential novel therapeutic targets.

Abstract
MicroRNA (miR)-106b-5p has been reported to act as both an oncogene and tumor suppressor in several tumors. The aim of the present study was to investigate the biological function of miR-106b-5p in osteosarcoma (OS). miR-106b-5p expression was observed to be significantly increased in OS tissues and cell lines. MTT assay and flow cytometry analysis determined that miR-106b-5p inhibitor transfection suppressed OS cell proliferation and induced cell cycle G0/G1 phase arrest. Furthermore, bioinformatics analysis and a luciferase reporter assay demonstrated that cyclin-dependent kinase inhibitor 1A (CDKN1A) was a potential target of miR-106b-5p. p21 protein expression was found to be significantly increased by miR-106b-5p downregulation in OS cells. Further analysis demonstrated that CDKN1A was downregulated in OS tissues and was negatively correlated with miR-106b-5p expression. Furthermore, upregulation of CDKN1A expression mimicked, whilst CDKN1A knockdown reversed the suppressive effects of miR-106b-5p inhibitor on OS cell proliferation and cell cycle progression. In summary, the present data suggested that miR-106b-5p promotes cell proliferation and cell cycle progression by directly targeting CDKN1A in OS.

Abstract
BACKGROUND Multidimensional data mining from an integrated environment of different data sources is frequently performed in computational system biology. The molecular mechanism from the analysis of a complex network of gene-miRNA can aid to diagnosis and treatment of associated diseases. METHODS In this work, we mainly focus on finding inflammatory bowel disease (IBD) associated microRNAs (miRNAs) by biclustering the miRNA-target interactions aided by known IBD risk genes and their associated miRNAs collected from several sources. We rank different miRNAs by attributing to the dataset size and connectivity of IBD associated genes in the miRNA regulatory modules from biclusters. We search the association of some top-ranking miRNAs to IBD related diseases. We also search the network of discovered miRNAs to different diseases and evaluate the similarity of those diseases to IBD. RESULTS According to different literature, our results show the significance of top-ranking miRNA to IBD or related diseases. The ratio analysis supports our ranking method where the top 20 miRNA has approximately tenfold attachment to IBD genes. From disease-associated miRNA network analysis we found that 71% of different diseases attached to those miRNAs show more than 0.75 similarity scores to IBD. CONCLUSION We successfully identify some miRNAs related to IBD where the scoring formula and disease-associated network analysis show the significance of our method. This method can be a promising approach for isolating miRNAs for similar types of diseases.

Abstract
Glioma is one of the most common malignant tumors and shows a high metastasis rate and poor prognosis. Abnormal expression of long non-coding RNAs (lncRNAs) contributes to various human tumors including gliomas. This study aimed to investigate the regulatory role of the antisense RNA of growth arrest special 5 (GAS5-AS1), a novel lncRNA, in gliomas. Expression of GAS5-AS1 and microRNA-106b-5p (miR-106b-5p) in glioma tissues and cells was detected by quantitative reverse transcription PCR, northern blotting, or fluorescent in situ hybridization. Cell proliferation, migration, and invasion were analyzed by CCK-8 and Transwell assays. BALB/c nude mice were used to establish a glioma xenograft animal model by subcutaneous injection of U251 cells transfected with small interfering RNA targeting GAS5-AS1. A dual-luciferase reporter assay was conducted to confirm the targeting relationship between GAS5-AS1 and miR-106b-5p. GAS5-AS1 expression was downregulated in glioma tissues and cells, and upregulation of GAS5-AS1 expression inhibited glioma cell proliferation, migration, and invasion. GAS5-AS1 expression was correlated with the glioma tumor grade. In nude mice, upregulation of GAS5-AS1 markedly suppressed glioma tumor growth. GAS5-AS1 overexpression significantly increased the miR-106b-5p level in glioma cells, and GAS5-AS1 expression was negatively related to miR-106b-5p expression in glioma tissues. Overexpression of miR-106b-5p reversed the inhibitory effects of GAS5-AS1 upregulation on glioma cell proliferation and metastasis, while restoration of TUSC2 rescued the proliferation and invasion of glioma cells transfected with miR-106b-5p mimics. In summary, lncRNA GAS5-AS1 inhibited glioma proliferation, migration, and invasion by sponging miR-106b-5p and regulating the expression of TUSC2. Our results suggest GAS5-AS1 as a novel target for the treatment and prognosis prediction of gliomas.

Abstract
Prostate cancer (PCa) is the most common malignancy among males worldwide, and is one of the leading causes of cancer‑related mortality. MicroRNAs (miRs) are a type of endogenous, noncoding RNA that serve a key role in pathological processes, and have been demonstrated to be involved in the formation and progression of PCa. Previous studies have reported that miR‑106b acts as an oncogene; however, the specific effects of miR‑106b on PCa have not been fully elucidated. The present study aimed to investigate the role and underlying molecular mechanisms of miR‑106b in the initiation and progression of PCa. In this study, miR‑106b was reported to be overexpressed and la‑related protein 4B (LARP4B) was downregulated in PCa tissues compared with paracancerous tissues. In addition, LARP4B was identified as a target gene of miR‑106b by bioinformatics prediction analysis and a dual luciferase reporter gene assay. Furthermore, MTT, wound healing and Transwell assays were performed to evaluate PCa cell viability, and migration and invasive abilities. The data revealed that inhibition of miR‑106b significantly suppressed the viability, migration and invasion of PCa cells. In addition, inhibition of miR‑106b significantly suppressed the mRNA and protein expression of cancer‑related genes, including matrix metalloproteinase‑2, cluster of differentiation 44 and Ki‑67, and increased that of the tumor suppressor, mothers against decapentaplegic homolog 2. Collectively, the findings of the present study indicated that miR‑106b may target LAR4B to inhibit cancer cell viability, migration and invasion, and may be considered as a novel therapeutic target in PCa.

Abstract
The recent developments in Cathepsin protease research have unveiled a number of key observations which are fundamental to further our understanding of normal cellular homeostasis and disease. By far, the most interesting and promising area of Cathepsin biology stems from how these proteins are linked to the fate of living cells through the phenomenon of Lysosomal Leakage and Lysosomal Membrane Permeabilisation. While extracellular Cathepsins are generally believed to be of central importance in tumour progression, through their ability to modulate the architecture of the Extracellular Matrix, intracellular Cathepsins have been established as being of extreme significance in mediating cell death through Apoptosis. With these two juxtaposed key research areas in mind, the focus of this review highlights recent advancements in how this fast-paced area of Cathepsin research has recently evolved in the context of their mechanistic regulation in cancer research.
