Abstract
Background and Objectives Irbesartan has been widely used in the clinical treatment of diabetic kidney disease (DKD). However, the molecular mechanism of its delay of DKD disease progression has not been fully elucidated. The aim of the present study was to investigate the mechanism of irbesartan in the treatment of DKD. Materials and Methods C57BL/KsJ db/db mice were randomly divided into the model group and irbesartan-treated group. After treatment with irbesartan for 12 weeks, the effects on blood glucose, body weight, 24-h urinary albumin, and renal injuries were evaluated. Microarray was used to determine the differentially expressed genes (DEGs) in the renal cortex of mice. |Log FC| <0.5 and false discovery rate (FDR) <0.25 were set as the screening criteria. Kyoto Encyclopedia of Genes and Genomes (KEGG), gene ontology (GO), protein-protein interaction (PPI) network and modules, and microRNA (miRNA)-DEGs network analysis were applied to analyze the DEGs. Furthermore, quantitative real-time polymerase chain reaction (qRT-PCR) was used to validate the results of microarray. Results The present study demonstrated irbesartan could significantly improve the renal function in db/db mice through decreasing 24-h urinary albumin and alleviating the pathological injury of kidney. Irbesartan may affect the expression of numerous kidney genes involved in circadian rhythm, cell cycle, micoRNAs in cancer, and PI3K-AKT signaling pathway. In the miRNA-DEGs network, miR-1970, miR-703, miR-466f, miR-5135, and miR-132-3p were the potential targets for irbesartan treatment. The validation test confirmed that key genes regulating circadian rhythm (Arntl, Per3, and Dbp) and cell cycle (Prc1, Ccna2, and Ccnb2) were restored in db/db mice on treatment with Irbesartan. Conclusion Generally, irbesartan can effectively treat DKD by regulating the circadian rhythm and cell cycle. The DEGs and pathways identified in the study will provide new insights into the potential mechanisms of irbesartan in the treatment of DKD.

Role of Hippocampal miR-132-3p in Modifying the Function of Protein Phosphatase Mg2+/Mn2+-dependent 1 F in Depression. Neurochem Res 2023:10.1007/s11064-023-03926-8. [PMID: 37036545 DOI: 10.1007/s11064-023-03926-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2022] [Revised: 03/15/2023] [Accepted: 03/28/2023] [Indexed: 04/11/2023]
Abstract
Depression is a common, severe, and debilitating psychiatric disorder of unclear etiology. Our previous study has shown that protein phosphatase Mg2+/Mn2+-dependent 1F (PPM1F) in the hippocampal dentate gyrus (DG) displays significant regulatory effects in depression-related behaviors. miR-132-3p plays a potential role in the etiology of depression. This study explored the effect of miR-132-3p on the onset of depression and the possible underlying mechanism for modulating PPM1F expression during the pathology of depression. We found that miR-132-3p levels in the hippocampus of depressed mice subjected to chronic unpredictable stress (CUS) were dramatically reduced, which were correlated with depression-related behaviors. Knockdown of miR-132-3p in hippocampal DG resulted in depression-related phenotypes and increased susceptibility to stress. miR-132-3p overexpression in hippocampal DG alleviated CUS-induced depression-related performance. We then screened out the potential target genes of miR-132-3p, and we found that the expression profiles of sterol regulatory element-binding transcription factor 1 (Srebf1) and forkhead box protein O3a (FOXO3a) were positively correlated with PPM1F under the condition of miR-132-3p knockdown. Finally, as anticipated, we revealed that the activities of Ca2+/calmodulin-dependent protein kinase II (CAMKII) and adenosine 5'-monophosphate (AMP)-activated protein kinase (AMPK) were reduced, which underlies the target signaling pathway of PPM1F. In conclusion, our study suggests that miR-132-3p was designed to regulate depression-related behaviors by indirectly regulating PPM1F and targeting Srebf1 and FOXO3a, which have been linked to the pathogenesis and treatment of depression.

Abstract
Cadmium (Cd) is an environmental pollutant produced by industrial activities, which has no known physiological benefits to organisms. In our previous study, the transcriptomic profiles of carp head kidney exposed to Cd was analyzed by genomics technique, and confirmed that miRNAs are important in the head kidney injury of carp induced by Cd, but the specific biological mechanism was unclear. In order to further explore the effect of Cd on carp head kidney lymphocyte damage, we established a model of Cd exposure in vitro. The results showed that Cd could increase the expression of Bax (Bcl-2 associated X protein), Caspase9 (Cysteinyl aspartate specific proteinase 9) and Caspase3 (Cysteinyl aspartate specific proteinase 3), inhibit the expression of Bcl-2 (B cell lymphoma/leukemia 2), and induce apoptosis of carp head kidney lymphocytes. In our previous study, we screened the differentially expressed miRNA in Cd-treated lymphocytes by high-throughput sequencing, and found that there was a significant difference in the expression of miR-9-5p. The expression trend of miR-9-5p in the vitro model was the same as that of high-throughput sequencing. We screened the differentially expressed gene FKBP5 (FK506-binding protein 51) in lymphocytes treated with Cd. It was confirmed by double luciferase reporter gene analysis that FKBP5 was the target gene of miR-9-5p. We established the overexpression/knockdown model of miR-9-5p in carp head kidney lymphocyte in vitro. The results showed that miR-9-5p could inhibit the expression of FKBP5, increase the phosphorylation level of Akt, inhibit apoptosis and improve the cell survival rate in carp head kidney lymphocytes. Together, Cd could down-regulate the expression of miR-9-5p, target up-regulate the expression of FKBP5, inhibit the phosphorylation of Akt, and promote the apoptosis of carp head kidney lymphocytes through mitochondrial pathway.

Abstract
Cadmium (Cd) is one of the most harmful environmental pollutants and has been found to have adverse effects on the gut. However, the toxic effects and potential mechanism of Cd on intestinal epithelial cells (IECs) are poorly understood. This study evaluated the effects of Cd exposure (0, 0.25, 0.5, 1, 2, and 4 μM) on IEC-6 cells in terms of cell viability and apoptosis, as well as apoptosis-associated gene expression. The results indicated that low doses (0.25- 1 μM) of Cd exhibited hormetic effects, while high doses of Cd (2 and 4 μM) reduced cell viability. The apoptotic effect increased in a dose-dependent pattern. Moreover, the mRNA levels of the Bcl-2, Bax and Caspase 3 genes were altered, which was in agreement with their protein expression. Based on sequencing analysis, the expression pattern of the microRNAs (miRNAs) changed significantly in the 2 μM Cd-treated group. QRT-PCR verified that 7 miRNAs, including miR-124-3p and miR-370-3p, were all upregulated with dose-effect relationship. Besides, transfection of miR-124-3p and miR-370-3p mimics /inhibitor and Bcl-2 siRNA into IEC-6 cells verified that these two miRNAs could regulate Cd-induced apoptosis by targeting Bcl-2. Finally, the direct targeting relationship between miR-370-3p and Bcl-2 gene was confirmed by luciferase reporter assay. Overall, the results demonstrated that Cd exposure could induce apoptosis in IEC-6 cells. The potential mechanism may be interference with the regulation of Bcl-2 gene expression by miR-370-3p and miR-124-3p.

Abstract
Background: Diabetic retinopathy (DR) is the most important manifestation of diabetic microangiopathy. MicroRNAs (miRNAs), members of non-coding RNAs, have been frequently reported to regulate various diseases including DR. MiR-124-3p is involved in DR based on bioinformatics. The current study aimed to investigate the role of miR-124-3p in high glucose (HG)-treated human retinal microvascular endothelial cells (HRMECs), an in vitro model of DR. Methods: Bioinformatics analysis was applied to reveal the targets downstream miR-124-3p. A series of assays including CCK-8, luciferase reporter, western blot, and tube formation assays were used to explore the function and mechanism of miR-124-3p in HG-stimulated HRMECs. Results: We found out that miR-124-3p was downregulated in HG-stimulated HRMECs. Functionally, miR-124-3p overexpression restrained the HG-induced cell injury of HRMECs. Mechanistically, we predicted 5 potential target mRNAs of miR-124-3p. G3BP stress granule assembly factor 2 (G3BP2) was validated to bind with miR-124-3p. Rescue assays showed that miR-124-3p suppressed cell injury of HG-stimulated HRMECs through G3BP2. In addition, miR-124-3p regulated the p38MAPK signaling pathway by G3BP2, and G3BP2 promoted injury of HG-treated HRMECs through the activation of the p38MAPK signaling pathway. Conclusion: MiR-124-3p suppressed the dysfunctions of HG-treated HRMECs by targeting G3BP2 and activating the p38MAPK signaling. This new discovery provided a potential biomarker for DR treatment.

Abstract
AIMS Focal segmental glomerulosclerosis (FSGS) is the common cause of chronic renal disease worldwide. Although there are many etiologic factors which have common theme of podocyte injury conclusive etiology is not clearly understood. In this study, we aimed to explore the role of autophagy in the pathogenesis of podocyte injury, which is the key point in disease progression, and the roles of intrarenal microRNAs and the prorenin receptor (PRR) in the 5/6 nephrectomy and adriamycin nephropathy models of FSGS. MAIN METHODS For experimental FSGS model, 5/6 nephrectomy and adriamycin nephropathy models were created and characterized in adult Sprague Dawley rats. Microarray analysis was performed on FSGS and control groups that was confirmed by q-RT-PCR. Beclin1, LC3B, PRR, ATG7 and ATG5 expression were evaluated by western blotting and immunohistochemistry. Also, Beclin1 and PRR expression were measured by ELISA. Glomerular podocyte isolation was performed and autophagic activity was evaluated in podocytes before and after transfection with miRNA mimic and antagonists. KEY FINDINGS Glomerular expression of Beclin1, LC3B, PRR, ATG7 and ATG5 were significantly lower in the 5/6 nephrectomy than adriamycin nephropathy group and in both groups lower when compared to control groups. Western blot results were consistent with immunohistochemical data. Electron microscopy revealed signs of impaired autophagy in FSGS. Autophagic activity decreased significantly after miR-214, miR-132 and miR-34c mimics and increased after transfection with antagonists. SIGNIFICANCE These results showed that the role of autophagic activity and decreased expression of PRR in FSGS pathogenesis and miR-34c, miR-132 and miR-214 could be a potential treatment strategy by regulating autophagy.

Objective Tuberous sclerosis complex (TSC) is a rare autosomal dominant disease characterized by lesions throughout the body. Our previous study showed the abnormal up-regulation of miRNAs plays an important part in the pathogenesis of TSC-related renal angiomyolipoma (TSC-RAML). circRNAs were known as important regulators of miRNA, but little is known about the circRNAs in TSC-RAMLs. Methods Microarray chips and RNA sequencing were used to identify the circRNAs and mRNAs that were differently expressed between the TSC-RAML and normal kidney tissue. A competitive endogenous RNA (ceRNA) regulatory network was constructed to reveal the regulation of miRNAs and mRNAs by the circRNAs. The biological functions of circRNA and mRNA were analyzed by pathway analysis. Microenvironmental cell types were estimated with the MCP-counter package. Results We identified 491 differentially expressed circRNAs (DECs) and 212 differentially expressed genes (DEGs), and 6 DECs were further confirmed by q-PCR. A ceRNA regulatory network which included 6 DECs, 5 miRNAs, and 63 mRNAs was established. Lipid biosynthetic process was significantly up-regulated in TSC-RAML, and the humoral immune response and the leukocyte chemotaxis pathway were found to be down-regulated. Fibroblasts are enriched in TSC-RAML, and the up-regulation of circRNA_000799 and circRNA_025332 may be significantly correlated to the infiltration of the fibroblasts. Conclusion circRNAs may regulate the lipid metabolism of TSC-RAML by regulation of the miRNAs. Fibroblasts are enriched in TSC-RAMLs, and the population of fibroblast may be related to the alteration of circRNAs of TSC-RAML. Lipid metabolism in fibroblasts is a potential treatment target for TSC-RAML. Supplementary Information The online version contains supplementary material available at 10.1186/s40246-021-00344-1.

Abstract
MicroRNAs are a group of short non-coding RNAs (miRNAs), which are epigenetically involved in gene expression and other cellular biological processes and can be considered as potential biomarkers for cancer detection and support for treatment management. This review aims to amass the evidence to reach the molecular mechanism and clinical significance of miR-132 in different types of cancer. Dysregulation of miR-132 level in various types of malignancies, including hepatocellular carcinoma, breast cancer, colorectal cancer, gastric cancer, lung cancer, prostate cancer, osteosarcoma, pancreatic cancer, and ovarian cancer have reported, significantly decrease in its level, which can be indicated to its function as a tumor suppressor. miR-132 is involved in cell proliferation, migration, and invasion through cell cycle pathways, such as PI3K, TGFβ or hippo signaling pathways, or on oncogenes such as Ras, AKT, mTOR, glycolysis. miR-132 could be potentially a candidate as a valuable biomarker for prognosis in various cancers. Through this study, we proposed that miR-132 can potentially be a candidate as a prognostic marker for early detection of tumor development, progression, as well as metastasis.

Abstract
Background MicroRNAs (miRNAs) often appear as oncogenes or tumor suppressor genes. The aim of this research was to examine miR-132-3p and Kruppel-like factor 7 (KLF7) effects in the development of non-small cell lung cancer (NSCLC). Methods We used quantitative reverse transcription polymerase chain reaction (qRT-PCR) to determine miR-132-3p expression in tissue specimens and 6 cells (A549, H1650, H292, H1299, H1944, BEAS-2b). Luciferase report forecasted the targeting relationship between miR-132-3p and KLF7. The expression of KLF7 and interstitial protein was determined by western blot. Proliferation test and Transwell assay were adopted for examining cell development. The Cell Counting Kit-8 (CCK-8) colorimetric method was used to observe the effects of miR-132-3p and KLF7 on the proliferation, metastasis, and invasion of NSCLC tumor cells. In order to determine whether the metastasis of NSCLC tumor cells was epithelial-mesenchymal transition (EMT)-mediated, supplementary experiments with E-cadherin and vimentin were performed. Results An increased expression of miR-132-3p was detected in NSCLC. Its mimic promoted the proliferation of tumor cells. As an immediate site of miR-132-3p, KLF7 was reversely adjusted via miR-132-3p and restrained the development of tumor cells in NSCLC, the effects of which were attenuated via KLF7 over-expression. Besides, the presence of EMT-related diversions was confirmed in NSCLC. Conclusions By targeting KLF7, miR-132-3p was capable of promoting the proceeding of NSCLC tumor cells. We discovered miR-132-3p/KLF7 route may exhibit curative target for NSCLC.

Abstract
Objective: This study aimed to observe the effect of miR-9-5p and CPEB3 on hepatocellular carcinoma (HCC) cells, and investigate the underlying targeting regulatory mechanism. Materials & methods: Various experiments like CCK-8, colony formation assay, wound healing assay and Transwell were performed for cancer cell activities detection, including cell proliferation, growth activity, migration and invasion. Results: MiR-9-5p was found to be highly expressed in HCC cells, while CPEB3 was poorly expressed (p < 0.05). The overexpression of miR-9-5p and the silencing of CPEB3 both could significantly promote cell proliferation, migration and invasion (p < 0.05). In addition, miR-9-5p could target to downregulate CPEB3 expression, thus accelerating cell proliferation, migration, invasion and epithelial-mesenchymal transition process in HCC. Conclusion: MiR-9-5p can target CPEB3, thereby promoting cell proliferation, migration and invasion in HCC. The axis of miR-9-5p/CPEB3 is expected to become a potential therapeutic target beneficial for HCC patients.

Abstract
OBJECTIVES To investigate the clinical utility of serum microRNA levels (miR-9-5p and miR-128-3p) in the diagnosis and prognosis of early-stage acute ischemic stroke (AIS). METHODS We compared the differences in serum miR-9-5p and miR-128-3p levels between patients with AIS and healthy individuals (controls). The serum levels of miR-9-5p and miR-128-3p were quantified using quantitative real-time PCR, and the association of each miRNA with AIS was determined using receiver operator characteristic curve analysis. The predictive value of these indices in the diagnosis of early-stage AIS was evaluated in conjunction with that of computed tomography findings and neuron-specific enolase levels. The prognosis of patients with AIS was evaluated three months after their discharge from hospital using the modified Rankin scale, which classifies the prognosis as either favorable or poor. Logistic regression analysis was used to analyze the correlation between miR-9-5p and miR-128-3p levels and patient prognosis. RESULTS The serum levels of miR-9-5p and miR-128-3p were upregulated in patients with AIS relative to those in healthy individuals. A pronounced correlation was identified between serum miR-9-5p and miR-128-3p levels and patient prognosis, with high levels of both miRNAs being associated with poor patient outcomes. CONCLUSION Assessment of serum miR-9-5p and miR-128-3p levels is important for the early diagnosis and prognosis of AIS.

MicroRNA-124-3p affects myogenic differentiation of adipose-derived stem cells by targeting Caveolin-1 during pelvic floor dysfunction in Sprague Dawley rats. ANNALS OF TRANSLATIONAL MEDICINE 2021; 9:161.

Abstract
Background The aim of this study was to investigate using myogenic differentiation of adipose stem cells for the treatment of female pelvic floor dysfunction (PFD) and aimed to further study the influences of microRNA-124-3p (miR-124-3p) in the process of myogenic differentiation of adipose-derived stem cells (ADSCs) through targeting Caveolin-1 (Cav1) during PFD in Sprague Dawley (SD) rats. Methods The ADSCs were separated from 6–8-week-old female SD rats (n=25) and were cultivated. Then, we observed the cell status and conducted fat and osteogenic experiments. We then constructed an ADSC-green fluorescent protein (GFP) stable transfer strain. Flow cytometry was used to identify the positive rates of CD44, CD90, and CD45 in ADSCs and ADSC-GFP. Real-time quantitative polymerase chain reaction (qRT-PCR) and western blotting were used to mRNA and protein expression levels. Myogenic differentiation of ADSCs was measured with immunofluorescence methods. A dual-luciferase reporter assay was executed to affirm whether Cav1 was a target of miR-124-3p. Results The isolated ADSCs cells were in good condition under the microscope. The results of flow cytometry showed that the positive rate of CD44 and CD90 was high, and the positive rate of CD45 was low in ADSCs and ADSC-GFP. Under normal culture conditions, ADSCs-GFP cells can be massively adipated and osteogenic. After 5-Aza induced ADSC-GFP myogenic differentiation, the level of miR-124-3p was significantly increased. We found that MiR-124-3p mimics promoted the myogenic differentiation of ADSCs. Moreover, we discovered that Cav1 was a target gene of miR-124-3p and was negatively regulated by miR-124-3p. The results of leak point pressure (LPP), hematoxylin and eosin (HE), and Masson showed that the collagen fiber content of the PFD group was lower than that of the control group; the collagen fiber content of ADSC-GFP, 5-Aza, or miR-124-3p mimics were increased after intervention. Furthermore, the outcomes qRT-PCR, western blotting, and immunofluorescence suggested that miR-124-3p facilitated the survival ADSC-GFP fat transplantation by regulating many key factors in vivo. Conclusions These results proofed that miR-124-3p could accelerate myogenic differentiation of ADSCs by down-regulating Cav1 to improve PFD in SD rats, which will pave the way for therapeutic delivery of miRNA targeting PFD disease.

Abstract
RAS p21 protein activator 1 (RASA1), also known as p120-RasGAP, is a RasGAP protein that functions as a signaling scaffold protein, regulating pivotal signal cascades. However, its biological mechanism in renal cell carcinoma (RCC) remains unknown. In the present study, RASA1, F-box/WD repeat-containing protein 7 (FBXW7), and miR-223-3p expression were assessed via quantitative reverse transcription-polymerase chain reaction (qRT-PCR) and Western blot. Then, the targeted correlations of miR-223-3p with FBXW7 and RASA1 were verified via a dual-luciferase reporter gene assay. CCK-8, flow cytometry, and Transwell assays were implemented independently to explore the impact of RASA1 on cell proliferation, apoptosis, migration, and cell cycle progression. Finally, the influence of RASA1 on tumor formation in RCC was assessed in vivo through the analysis of tumor growth in nude mice. Results showed that FBXW7 and RASA1 expression were decreased in RCC tissues and cell lines, while miR-223-3p was expressed at a higher level. Additionally, FBXW7 and RASA1 inhibited cell proliferation but facilitated the population of RCC cells in the G0/G1 phase. Altogether, RASA1 may play a key role in the progression of RCC by decreasing miR-223-3p and subsequently increasing FBXW7 expression.

Abstract
Background Large amounts of researches indicate that non-coding RNAs play a crucial role in many malignancies. However, the potential mechanisms of non-coding RNAs involved in osteosarcoma tumorigenesis remain elusive. Materials and Methods The expression of long non-protein coding RNA 691 (lncRNA 691) in cell lines and paired osteosarcoma tissues was compared by qRT-PCR assay. Then, we explored the tumor suppressor function of lncRNA 691 with MTS and colony formation assay. Flow cytometry results showed lncRNA 691 can enhance cell apoptosis. Then, we predicted and verified the negative regulation relationship with miRNA and the miRNA’s target gene. Lastly, we revealed the tumorigenesis function of lncRNA-691/miRNA/target gene axis in osteosarcoma. Results In our study, we disclosed that lncRNA 691 had low expression levels in osteosarcoma cell lines and tissues. Overexpression of lncRNA 691 could suppress the cell proliferation and induce cell apoptosis in MG-63 cell line. Then, bioinformatics analyses were performed and miR-9-5p was found to negatively regulate the lncRNA 691 expression and promote the osteosarcoma tumorigenesis in vitro. PTEN was predicted as the target gene of miR-9-5p. Luciferase reporter assay and RIP assay demonstrated the regulatory network of lncRNA 691/miR-9-5p/PTEN. We revealed that PTEN was downregulated by the overexpression of miR-9-5p and upregulated by the overexpression of lncRNA 691. At last, the apoptosis-associated protein of the lncRNA 691/miR-9-5p/PTEN/PI3K/AKT was further demonstrated. Conclusion LncRNA 691/miR-9-5p could regulate the tumorigenesis by regulating the PTEN/PI3K/AKT signal pathway in osteosarcoma.

Abstract
In the early stage of ovarian cancer (OC), molecular biomarkers are critical for its diagnosis and treatment. Nevertheless, there is little research on the mechanism underlying tumorigenesis in OC. Herein, we aimed to explore whether long noncoding RNA (lncRNA) HAND2-AS1 participated in the regulation of the cell proliferation, migration, and apoptosis of OC by regulating B-cell lymphoma 2 like 11 (BCL2L11) and microRNA-340-5p (miR-340-5p). Differentially expressed lncRNAs in OC were screened by microarray-based analysis. HAND2-AS1, BCL2L11, and miR-340-5p expression was assessed in normal ovarian and OC tissues and human OC cell lines. Then, the relationships among HAND2-AS1, BCL2L11, and miR-340-5p were explored. Ectopic expression and depletion experiments were applied to analyze the effects of HAND2-AS1, miR-340-5p and BCL2L11 on migration, invasion, and proliferation of OC cells, as well as apoptosis. Lastly, the tumor xenograft in nude mice was conducted to test the tumorigenesis in vivo. In silico analysis displayed poor expression of HAND2-AS1 in OC. HAND2-AS1 specifically sponged with miR-340-5p which was found to directly target BCL2L11. Importantly, HAND2-AS1 or BCL2L11 overexpression or miR-340-5p downregulation resulted in reduction of cell invasion and migration, together with decrease of cell proliferation and increase of cell apoptosis in OC. Besides, high-expressed HAND2-AS1 inhibited the tumorigenesis in nude mice. To sum up, these data suggests HAND2-AS1 as an anti-oncogene in OC through upregulation of BCL2L11 by competitively binding to miR-340-5p, which demonstrates that there are potential diagnosis and therapy values of HAND2-AS1 in OC.

Abstract
MicroRNAs (miRNAs/miRs) have been reported to be closely associated with numerous human diseases, including cholangiocarcinoma (CCA). However, the number of miRNAs known to be involved in CCA is limited, and the association between miR-132-3p and CCA remains unknown. In the present study, the clinical role of miR-132-3p and its potential signaling pathways were investigated by multiple approaches. Reverse transcription-quantitative PCR (RT-qPCR), CCA-associated Gene Expression Omnibus (GEO), ArrayExpress and Sequence Read Archive (SRA) miRNA-microarray or miRNA-sequencing data were screened, and meta-analyses were conducted, in order to calculate the receiver operating characteristic (ROC) curve and standardized mean difference (SMD). The predicted target genes of miR-132-3p were obtained from 12 online databases and were combined with the downregulated differentially expressed genes identified in the RNA-sequencing data of CCA. Gene Ontology annotation and pathway analysis were performed in WebGestalt. Protein-protein interaction analyses were conducted in STRING. The Cancer Genome Atlas (TCGA) mRNA expression profiles were used to validate the expression levels of hub genes at the mRNA level. The Human Protein Atlas was used to identify the protein expression levels of hub genes in CCA tissues and non-tumor biliary epithelium. The meta-analyses comprised 10 groups of RT-qPCR data, eight GEO microarray datasets and one TCGA miRNA-sequencing dataset. The SMD of miR-132-3p in CCA was 0.75 (95% CI: 0.25, 1.24), which indicated that miR-132-3p was overexpressed in CCA tissues. This finding was supported by a summary ROC value of 0.80 (95% CI: 0.76, 0.83). The pooled sensitivity and specificity were 0.81 (95% CI: 0.59, 0.93) and 0.71 (95% CI: 0.58, 0.81), respectively. The relative expression level of miR-132-3p in the early stage of CCA (stages I–II) was 6.8754±0.5279, which was markedly lower than that in the advanced stage (stages III–IVB), 7.3034±0.3267 (P=0.003). Consistently, the miR-132-3p level in low-grade CCA (grades G1-G2) was 6.7581±0.5297, whereas it was 7.1191±0.4651 in patients with high-grade CCA (grades G3-G4) (P=0.037). Furthermore, 555 potential target genes of miR-132-3p in CCA were mainly enriched in the ‘Focal Adhesion-PI3K-Akt-mTOR-signaling pathway’. In conclusion, upregulation of miR-132-3p may serve a pivotal role in the tumorigenesis and progression of CCA by targeting different pathways. Further in vitro and in vivo studies are required to support the current findings.

[PMID: 31480990 PMCID: PMC6769294 DOI: 10.1098/rsob.190074] [Citation(s) in RCA: 34] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2019] [Accepted: 07/24/2019] [Indexed: 12/25/2022] Open
Abstract
The aim of this study was to analyse the expression pattern and elucidate the mechanistic involvement of long non-coding RNA LINC00467 in hepatocellular carcinoma (HCC). The relative expression of LINC00467 and microRNA (miR)-9-5p was determined by real-time polymerase chain reaction. Cell viability was measured using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. The cell proliferation was analysed by cell counting. Cell migration and invasion were monitored by Transwell assay. The luciferase reporter assay was employed to investigate the regulatory effect of miR-9-5p on LINC00467 and peroxisome proliferator-activated receptor alpha (PPARA). The endogenous PPARA protein was quantified by western blotting. It was found that LINC00467 was aberrantly decreased in HCC. The ectopic expression of LINC00467 significantly suppressed cell viability, proliferation, migration and invasion. LINC00467 functioned as a sponge for miR-9-5a and negatively regulated miR-9-5p expression. We also identified PPARA as the direct target of miR-9-5p. siRNA-mediated knockdown of PPARA in LINC00467-proficient cells promoted cell viability, migration and invasion. Our data indicate the critical involvement of LINC00467/miR-9-5p/PPARA signalling in the incidence and progression of HCC.

Abstract
To investigate the expression status of FAM98A and its potential involvement in endometrial carcinoma, the relative expression of FAM98A in clinical endometrial carcinoma tissues was analyzed by immunohistochemistry and real-time polymerase chain reaction. Endogenous FAM98A protein was determined by Western blotting. The overall survival was calculated by the Kaplan-Meier's analysis. Cell growth/viability/proliferation was evaluated by cell counting, 3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide assay, and clonogenic assay, respectively. Cell apoptosis was determined by the Annexin V/7-AAD double-staining methods followed by flow cytometry analysis. The regulatory effect of miR-142-3p on FAM98A was interrogated by luciferase reporter assay. Aberrant overexpression of FAM98A was found in endometrial carcinoma both in vitro and in vivo. Furthermore, high level of FMA98A was associated with poor prognosis. FAM98A deficiency in Ishikawa and RL95-2 cells significantly inhibited cell growth, cell viability, and cell proliferation. In addition, FAM98A-knockdown stimulated remarkable cell apoptosis, which might be mediated by down-regulation of BCL2 and up-regulation of BAX. Mechanistically, it was demonstrated that miR-142-3p directly targeted FAM98A, and modulated its expression. In conclusion, we unraveled the oncogenic properties of FAM98A in endometrial carcinoma and highlighted the miR-142-3p-FAM98A signaling in this disease.

Chen L, Hu W, Li G, Guo Y, Wan Z, Yu J. Inhibition of miR-9-5p suppresses prostate cancer progress by targeting StarD13. Cell Mol Biol Lett 2019; 24:20. [PMID: 30899277 PMCID: PMC6408831 DOI: 10.1186/s11658-019-0145-1] [Citation(s) in RCA: 38] [Impact Index Per Article: 7.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2018] [Accepted: 02/25/2019] [Indexed: 12/21/2022] Open
Abstract
Background This study aims to investigate the effects of inhibiting microRNA-9-5p (miR-9-5p) on the expression of StAR-related lipid transfer domain containing 13 (StarD13) and the progress of prostate cancer. Methods The mRNA expression levels of miR-9-5p and StarD13 were determined in several prostate cancer cell lines. We chose DU145 and PC-3 cells for further research. The CCK8 assay was used to measure the cell viability. The cell invasion and wound-healing assays were respectively applied to evaluate invasion and migration. The expression of E-cadherin (E-cad), N-cadherin (N-cad) and vimentin were measured via western blot. DU145 and PC-3 cells overexpressing StarD13 were generated to investigate the variation in proliferation, invasion and migration. A luciferase reporter assay was used to identify the target of miR-9-5p. Results Our results show that miR-9-5p was highly expressed and StarD13 was suppressed in prostate cancer cells. MiR-9-5p inhibition repressed the cells’ viability, invasion and migration. It also increased the expression of E-cad and decreased that of N-cad and vimentin. StarD13 overexpression gave the same results as silencing of miR-9-5p: suppression of cell proliferation, invasion and migration. The bioinformatics analysis predicted StarD13 as a target gene of miR-9-5p. Quantitative RT-PCR, western blot analysis and the dual-luciferase reporter assay were employed to confirm the prediction. Conclusion Our results show that miR-9-5p plays a powerful role in the growth, invasion, migration and epithelial–mesenchymal transition (EMT) of prostate cancer cells by regulating StarD13. A therapeutic agent inhibiting miR-9-5p could act as a tumor suppressor for prostate cancer.
