J Cancer Res Clin Oncol 2023; 149:6883-6899. [PMID: 36810816 DOI: 10.1007/s00432-023-04624-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2022] [Accepted: 01/27/2023] [Indexed: 02/24/2023]
Abstract
BACKGROUND Colorectal cancer (CRC) is one of the most frequently diagnosed cancers. Polo-like kinase 1 (PLK1), a member of the serine/threonine kinase PLK family, is the most investigated and essential in the regulation of cell cycle progression, including chromosome segregation, centrosome maturation and cytokinesis. However, the nonmitotic role of PLK1 in CRC is poorly understood. In this study, we explored the tumorigenic effects of PLK1 and its potential as a therapeutic target in CRC. METHODS GEPIA database and immunohistochemistry analysis were performed to evaluate the abnormal expression of PLK1 in CRC patients. MTT assay, colony formation and transwell assay were performed to assess cell viability, colony formation ability and migration ability after inhibiting PLK1 by RNAi or the small molecule inhibitor BI6727. Cell apoptosis, mitochondrial membrane potential (MMP) and ROS levels were evaluated by flow cytometry. Bioluminescence imaging was performed to evaluate the impact of PLK1 on CRC cell survival in a preclinical model. Finally, xenograft tumor model was established to study the effect of PLK1 inhibition on tumor growth. RESULTS First, immunohistochemistry analysis revealed the significant accumulation of PLK1 in patient-derived CRC tissues compared with adjacent healthy tissues. Furthermore, PLK1 inhibition genetically or pharmacologically significantly reduced cell viability, migration and colony formation, and triggered apoptosis of CRC cells. Additionally, we found that PLK1 inhibition elevated cellular reactive oxygen species (ROS) accumulation and decreased the Bcl2/Bax ratio, which led to mitochondrial dysfunction and the release of Cytochrome c, a key process in initiating cell apoptosis. CONCLUSION These data provide new insights into the pathogenesis of CRC and support the potential value of PLK1 as an appealing target for CRC treatment. Overall, the underlying mechanism of inhibiting PLK1-induced apoptosis indicates that the PLK1 inhibitor BI6727 may be a novel potential therapeutic strategy in the treatment of CRC.

Lipid Handling Protein Gene Expression in Colorectal Cancer: CD36 and Targeting miRNAs. LIFE (BASEL, SWITZERLAND) 2022; 12:life12122127. [PMID: 36556492 PMCID: PMC9786157 DOI: 10.3390/life12122127] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/30/2022] [Revised: 12/09/2022] [Accepted: 12/14/2022] [Indexed: 12/24/2022]
Abstract
The reprogramming of lipid metabolism has been highlighted in colorectal cancer (CRC) studies, suggesting a critical role for the scavenger receptor CD36 and fatty acid synthase (FASN) in this malignancy. In this study, we analyzed the gene expression levels of CD36, FASN, the cell surface glypican 4 (GPC4), and the two transporters SLC27A3 and SLC27A4 in 39 paired tumoral and peritumoral tissues from patients with CRC compared with 18 normal colonic mucosae. Moreover, the levels of seven miRNAs targeting CD36 and most of the analyzed genes were evaluated. We found a significant impairment of the expression of all the analyzed genes except GPC4 as well as the differential expression of miR-16-5p, miR-26b-5p, miR-107, miR-195-5p, and miR-27a-3p in the colonic mucosa of CRC patients. Interestingly, CD36 and miR-27a-3p were downregulated and upregulated, respectively, in tumoral tissues compared to peritumoral and control tissues, with a significant negative correlation in the group of patients developing lymph node metastasis. Our results sustain the relationship between CRC and fatty acid metabolism and emphasize the importance of related miRNAs in developing new therapeutic strategies.

[PMID: 35710754 PMCID: PMC9203801 DOI: 10.1038/s41419-022-04750-8] [Citation(s) in RCA: 19] [Impact Index Per Article: 9.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2021] [Revised: 03/09/2022] [Accepted: 03/18/2022] [Indexed: 01/21/2023]
Abstract
Colorectal cancer (CRC) is one of the most prevalent and lethal malignancies. Exploring the underlying molecular mechanisms is very helpful for the development of new therapy. Here, we investigated the function of circMETTL3/miR-107/PER3 in CRC. Human CRC tissues from diagnosed CRC patients and six CRC cell lines, one normal human colon cell line were used. qRT-PCR and western blotting were performed to determine expression levels of RUNX3, circMETTL3, miR-107, PER3, and proliferation-, and migration-related proteins. CCK-8, colony formation assay, transwell assay, and scratch wound assay were utilized to assess CRC cell proliferation and invasion. ChIP, EMSA, biotin-pull down, RIP assay, and dual luciferase reporter assay were performed to validate interactions of RUNX3/METTL3 promoter, circMETTL3/miR-107, and miR-107/PER3. FISH was used to characterize circMETTL3. MSP was employed to measure methylation level. Nude mouse xenograft model was used to determine the effects on tumor growth and metastasis in vivo. RUNX3, circMETTL3, and PER3 were diminished while miR-107 was elevated in CRC tissues and cells. Low levels of RUNX3 and circMETTL3 correlated with poor prognosis of CRC. Overexpression of RUNX3, circMETTL3, or PER3 suppressed while miR-107 mimics promoted, CRC cell proliferation and invasion, as well as tumor growth and metastasis in vivo. Mechanistically, RUNX3 bound to METTL3 promoter and activated circMETTL3 transcription. circMETTL3 directly bound with miR-107 which targeted PER3. circMETTL3/miR-107 regulated CRC cell proliferation and invasion via PER3. CircMETTL3, transcriptionally activated by RUNX3, restrains CRC development and metastasis via acting as a miR-107 sponge to regulate PER3 signaling.

Abstract
Hypoxia in cancer is a thoroughly studied phenomenon, and the logical cause of the reduction in oxygen tension is tumor growth itself. While sustained hypoxia leads to death by necrosis in cells, there is an exquisitely regulated mechanism that rescues hypoxic cells from their fatal fate. The accumulation in the cytoplasm of the transcription factor HIF-1α, which, under normoxic conditions, is marked for degradation by a group of oxygen-sensing proteins known as prolyl hydroxylases (PHDs) in association with the von Hippel-Lindau anti-oncogene (VHL) is critical for the cell, as it regulates different mechanisms through the genes it induces. A group of microRNAs whose expression is regulated by HIF, collectively called hypoxaMIRs, have been recognized. In this review, we deal with the hypoxaMIRs that have been shown to be expressed in colorectal cancer. Subsequently, using data mining, we analyze a panel of hypoxaMIRs expressed in both normal and tumor tissues obtained from TCGA. Finally, we assess the impact of these hypoxaMIRs on cancer hallmarks through their target genes.

Abstract
Hypopharyngeal squamous cell carcinoma (HSCC) is one of the most common head and neck cancers, with a worst prognosis owing to its aggressivity. MicroRNA-107 (miR-107) is reported to regulate the progression of various cancers. Nevertheless, its implied function in HSCC remains unclear. This study is aimed to exploring the roles and potential mechanisms of miR-107 in HSCC. We found that miR-107 expression was significantly decreased in HSCC tissues compared with the para-cancer tissues. Moreover, miR-107 overexpression by miR-107 mimics decreased FaDu cell viability, led to cell cycle arrest in G1/S phase, accelerated apoptosis, and reduced cell migration and invasion. MiR-107 possibly resulted in deactivation of the phosphatidylinositol 3-kinase (PI3K)/Akt pathway, evidenced by the decrease of phosphorylated (p-) PI3K and p-Akt. Besides, dual-luciferase reporter assay confirmed that miR-107 might bind to the 3’UTR of Nin one binding protein 1 (NOB1), and elevated NOB1 expression in HSCC tissues and a negative correlation between miR-107 and NOB1 were found. Rescue assays demonstrated the significant roles of miR-107 in FaDu cell behavior by modulating NOB1. In addition, the tumorigenic potential of miR-107 in vivo was conducted. It was found that miR-107 overexpression in FaDu cells significantly inhibited tumor growth and led to inactivation of the PI3K/Akt signaling. The above findings revealed that miR-107 could suppress FaDu cell proliferation, migration, invasion and induced apoptosis by targeting NOB1 through the PI3K/Akt pathway, suggesting that miR-107/NOB1 axis may exert a key role in FaDu HSCC development.

Abstract
Background The incidence of gallbladder carcinoma (GBM) in China has increased in recent years. Here, the functional mechanism of lncRNA TTN-AS1 in GBC was preliminary elucidated. Methods The expression levels of lncRNA TTN-AS1, miR-107, and HMGA1 in tissues and cell lines were assessed by RT-qPCR. Cell proliferation was measured by MTT assays. Cell invasion and migration abilities were evaluated by Transwell assays. The relationship between miR-107 and lncRNA TTN-AS1 or HMGA1 was confirmed by luciferase reporter assay. Results Upregulation of lncRNA TTN-AS1 and downregulation of miR-107 were detected in GBC. Furthermore, the expressions between TTN-AS1 and miR-107 were mutually inhibited in GBC. Functionally, lncRNA TTN-AS1 promoted cell viability and motility in GBC by sponging miR-107. In addition, miR-107 directly targets HMGA1. And HMGA1 can be positively regulated by lncRNA TTN-AS1 in GBC. Furthermore, HMGA1 promoted GBC progression by interacting with lncRNA TTN-AS1/miR-107 axis. Conclusion LncRNA TTN-AS1 acted as a tumor promoter in GBC by sponging miR-107 and upregulating HMGA1.

[PMID: 34175590 DOI: 10.1016/j.phymed.2021.153603] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/23/2020] [Revised: 05/10/2021] [Accepted: 05/16/2021] [Indexed: 02/08/2023]
Abstract
BACKGROUND Apigenin (API) is a naturally occurring plant-derived flavone, which is abundantly present in common fruits and vegetables, and shows little or no toxicity of daily diet. The treatment of colorectal cancer is limited by high recurrence rate and multidrug resistance. PURPOSE The purpose of this study was to explore the potential therapeutic effect and possible mechanisms of API on colorectal cancer cells. METHODS Cell proliferation and apoptosis of human colon cancer cell line HCT116 was assessed after API treatment. A comprehensive transcriptome profile of API-treated HCT116 cells was acquired by high-throughput sequencing. The regulation of miRNA215-5p and E2F1/3 were identified by bioinformatics analyses. An inhibitor of miRNA215-5p, inhibitor 215, was applied to confirm the role of this microRNA played in the anti-cancer effect of API. Luciferase reporter gene assay was performed to identify targeting relationship between miRNA215-5p and E2F1/3. RESULT API significantly promoted cell apoptosis and anti-proliferation of HCT116 cells in a dose-dependent manner. Bioinformatics analyses identified several altered miRNAs among which the expression of miRNA-215-5p showed markedly increased. Meanwhile, the expression of E2F1 and E2F3 was decreased by API, which was associated with miRNA215-5p. Luciferase reporter gene assay showed miRNA-215-5p could directly bind to 3' UTR of E2F1/3. Inhibition of miRNA-215-5p significantly inhibited apoptosis and cell cycle arrest at G0/G1 phase induced by API. CONCLUSIONS The result of this study confirmed the anti-cancer effect of API on human colorectal cancer cells and investigated the underlying mechanism by a comprehensive transcriptome profile of API-treated cells.

Abstract
Background The prognosis of pancreatic cancer (PC) is relatively dismal due to the lack of effective therapy. In this study, we explored the specific functions and molecular mechanisms of miR-107 to uncover effective therapeutic targets for PC. Method The miR-107 expression in PC cell lines was assessed via quantitative real-time polymerase chain reaction (qRT-PCR). Besides, online bioinformatics analysis was adopted to predict the underlying targets of miR-107. Meanwhile, TCGA database was employed to explore the prognosis of PC patients. In addition, MTT and transwell assays were conducted to explore the PC cells’ biological functions. Result MiR-107 was remarkably increased in PC cells which could promote the proliferation, invasion and migration of PC cells. In addition, miR-107 could directly down-regulate TGFBR3 expression through binding to TGFBR3 3’UTR. Survival analysis from TCGA suggested that PC patients with higher miR-107 expression was significantly involved in poorer prognosis. Conclusion We concluded that miR-107 promoted proliferation, invasion and migration of PC cells via targeting TGFBR3, which may provide novel underlying therapeutic targets.

Abstract
Background Abnormally expressed in various tumors, long non-coding RNAs (lncRNAs) feature prominently in tumor development, yet little is still known regarding the functional roles of lncRNA AFAP1 antisense RNA 1 (AFAP1-AS1) in ovarian cancer (OC). Methods The relative expression levels of lncRNA AFAP1-AS1, microRNA (miR)-107 and pyruvate dehydrogenase kinase isozyme 4 (PDK4) mRNA were assessed by quantitative real-time PCR. PDK4, PCNA and cyclin D1 expression levels were determined using Western blot analysis. Bioinformatics analysis and dual-luciferase gene reporter assay were conducted for identifying and validating the binding sequences between AFAP1-AS1 and miR-107, as well as between miR-107 and PDK4. Cell counting kit-8 assay was employed for detecting cell proliferation. Cell migration and invasion abilities were examined using Transwell assays. Results The present study revealed that AFAP1-AS1 expression was elevated in OC cells and tissues. AFAP1-AS1 expression and FIGO stage were positively correlated. AFAP1-AS1 knockdown repressed OC cell proliferation, migration and invasion. AFAP1-AS1 functioned as a sponge of miR-107, and miR-107 reversed the effects of AFAP1-AS1 on OC cells. It was validated that miR-107 was able to bind to PDK4, and AFAP1-AS1 regulated PDK4 expression by competitively binding with miR-107. Additionally, miR-107 modulated OC cell proliferation, migration and invasion via targeting PDK4. Conclusions LncRNA AFAP1-AS1 serves as a tumor driver in the pathogenesis of OC via the miR-107/PDK4 axis.

Abstract
Long non-coding RNA (lncRNA) FYVE, RhoGEF and PH domain containing 5 antisense RNA 1 (FGD5-AS1) has been reported as an oncogene in colorectal cancer, promoting its tumorgenesis. The present paper focused on searching the potential function of FGD5-AS1 in non-small cell lung carcinoma (NSCLC). There are connections between the expression of lncRNA FGD5-AS1 and human NSCLC tumor growth and progression. Also, the relationships between FGD5-AS1, hsa-miR-107 and mRNA fibroblast growth factor receptor like 1 (FGFRL1) are going to test their interaction in NSCLC cell lines, which may cause a series of biological behaviors of NSCLC cells. qRT-PCR analysis was conducted to test the expression of RNAs in different situation. CCK-8 experiment and clone formation assay were performed to assess proliferation of NSCLC cells. Also, connection between FGD5-AS1 and hsa-miR-107 were investigated by luciferase reporter assay and RNA pull-down assay. Rescue experiments were performed to verify the modulating relationship between FGD5-AS1, hsa-miR-107 and FGFRL1. High-level expression of FGD5-AS1 was found in NSCLC. FGD5-AS1 may promote the proliferation of NSCLC cells. Also, the combination between hsa-miR-107, FGD5-AS1 and NSCLC have been proved, which means they can play an interaction function in NSCLC cells. Thence, we concluded that lncRNA FGD5-AS1 promotes non-small cell lung cancer cell proliferation through sponging hsa-miR-107 to up-regulate FGFRL1.

Abstract
Colorectal cancer is one of the most common cancers in the world. This study aimed to investigate the correlation between microRNA-107 (miR-107) expression level and the prognosis in colorectal cancer patients with its clinical significance. 80 cases of cancer tissues and 15 cases of adjacent cancer tissues were collected from colorectal cancer patients treated with surgery from February 2006 to January 2010. The expression of miR-107 was detected by real-time PCR. The correlation between miR-107 expression and clinic pathological factors and survival time of patients was statistically analyzed. The expression level of miR-107 in cancer tissues (0.0213 ± 0.0096) was significantly higher than that in adjacent tissues (0.0355 ± 0.0487). The expressions of miR-107 in patients with different TNM stages, Dukes stages, and lymph node metastasis rates were significantly different (P < 0.05). Cox proportional hazards regression model showed that miR-107 may be an independent factor affecting the prognosis of colorectal cancer patients (P < 0.05). The hazard ratio (HR) was 5.165. MiR-107 is highly expressed in colorectal cancer tissues and is closely related to the pathogenesis, progression, and metastasis of colorectal cancer. MiR-107 is expected to become a new molecular marker to assist the diagnosis, treatment effect and prognosis evaluation of colorectal cancer, and may also become a new target for colorectal cancer biotherapy.

Long non-coding RNA MIR503HG inhibits the proliferation, migration and invasion of colon cancer cells via miR-107/Par4 axis. Exp Cell Res 2020; 395:112205. [PMID: 32738347 DOI: 10.1016/j.yexcr.2020.112205] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2020] [Revised: 07/06/2020] [Accepted: 07/26/2020] [Indexed: 12/24/2022]
Abstract
PURPOSE Colon cancer is a common caner with high death rate in the world. The study aimed to detect the effect and mechanism of long non-coding RNA (LncRNA) MIR503HG on colon cancer. METHODS The MIR503HG expression was measured in colon cancer tissues and cell lines by qRT-PCR. The proliferation, apoptosis, migration and invasion of colon cancer cells were measured by MTT, flow-cytometry, wound healing and transwell assay. The protein expression of E-cadherin, N-cadherin, and Vimentin was detected by Western blot. The target relationships among MIR503HG, miR-107 and Par4 were predicted by StarBase and TargetScan, and verified by luciferase reporter and RNA pull-down assay. The xenograft tumor model was constructed in mice to verify the inhibitory effect of MIR503HG in vivo. RESULTS The expression of MIR503HG was decreased in colon cancer tissues and cell lines. MIR503HG overexpression inhibited cell proliferation, migration and invasion, promoted cell apoptosis, down-regulated N-cadherin and Vimentin, and up-regulated E-cadherin in colon cancer. MIR503HG negatively regulated its target miR-107. MiR-107 overexpression reversed the anti-tumor effects of MIR503HG overexpression on colon cancer cells. Par4 was a target of miR-107, which was positively regulated by MIR503HG. The promoting effects of MIR503HG silencing on colon cancer cells were eliminated by Par4 overexpression. CONCLUSION MIR503HG regulated Par4 via sponging miR-107 in colon cancer, which promoting a new idea for the treatment of colon cancer.

Abstract
Purpose Hepatocellular carcinoma (HCC) is one of the leading causes of cancer‐related death worldwide. Numerous analyses have revealed the abnormal expression of long non‐coding RNAs (lncRNAs) in HCC cells. This study aims to explore biological functions of lncRNA TMPO‐AS1 (TMPO antisense RNA 1) in HCC cell proliferation, apoptosis, invasion and migration. Methods The gene expression in HCC tissues and cell lines were measured by qRT‐PCR. The role of TMPO‐AS1 in HCC was confirmed by CCK‐8, colony formation, TUNEL, transwell and western blot as well as by in vivo experiments. RNA pull down and luciferase reporter assays were utilized to prove the binding relationship between TMPO‐AS1/FOXK1 (forkhead box K1) andmiR‐329‐3p. Rescue assays elucidated the regulatory effects of TMPO‐AS1/miR‐329‐3p/FOXK1/AKT/mTOR pathway on cellular activities in HCC. Results TMPO‐AS1was upregulated in HCC tissues and cells and its depletion inhibits HCC cell proliferation, invasion, migration, and EMT process as well as tumor growth. Furthermore, TMPO‐AS1 could bind with miR‐329‐3p, which suppressed HCC cell proliferation. FOXK1 served as the target gene of miR‐329‐3p and TMPO‐AS1 upregulated FOXK1 by sponging miR‐329‐3p in HCC cells. Additionally, FOXK1 overexpression or miR‐329‐3p inhibitor neutralized the repressing effects of TMPO‐AS1 knockdown on HCC development. Finally, it verified that TMPO‐AS1 could regulate AKT/mTOR pathway via FOXK1 to promote HCC. Conclusion TMPO‐AS1 contributes to HCC progression by sponging miR‐329‐3p to activate FOXK1‐mediated AKT/mTOR signaling pathway.

Abstract
Cardiac hypertrophy (CH) is a common cardiac disease and is closely associated with heart failure. Protocadherin 17 (PCDH17) was reported to aggravate myocardial infarction. Present study was designed to illustrate the impact of PCDH17 and the mechanism of PCDH17 expression regulation in CH. CH model in vivo and in vitro was established by transverse aortic constriction (TAC) and Ang‐II treatment. Hypertrophy was evaluated in PMC and H9c2 cells by examining cell surface area and hypertrophic markers. Results demonstrated that PCDH17 was up‐regulated in CH in vivo and in vitro. PCDH17 knock‐down alleviated hypertrophic response in Ang‐II‐induced cardiomyocytes. By means of ENCORI database and a series of mechanism assays, miR‐322‐5p and miR‐384‐5p were identified to interact with and inhibit PCDH17. Next, lncRNA SNHG14 (small nucleolar RNA host gene 14) was validated to sponge both miR‐322‐5p and miR‐384‐5p to elevate PCDH17 level. The subsequent rescue assays revealed that miR‐322‐5p and miR‐384‐5p restored SNHG14 depletion‐mediated suppression on hypertrophy in Ang‐II‐induced cardiomyocytes. Besides, Sp1 transcription factor (SP1) was verified as the transcription factor activating both SNHG14 and PCDH17. Both SNHG14 and PCDH17 reversed SP1 knock‐down‐mediated repression on hypertrophy in Ang‐II‐induced cardiomyocytes. Together, present study first uncovered ceRNA network of SNHG14/miR‐322‐5p/miR‐384‐5p/PCDH17 in Ang‐II‐induced cardiomyocytes.

Abstract
Background Long‐term use of doxorubicin (DOX) is limited by cumulative dose‐dependent cardiotoxicity. Objectives Identify plasma extracellular vesicle (EV)‐associated microRNAs (miRNAs) as a biomarker for cardiotoxicity in dogs by correlating changes with cardiac troponin I (cTnI) concentrations and, echocardiographic and histologic findings. Animals Prospective study of 9 client‐owned dogs diagnosed with sarcoma and receiving DOX single‐agent chemotherapy (total of 5 DOX treatments). Dogs with clinically relevant metastatic disease, preexisting heart disease, or breeds predisposed to cardiomyopathy were excluded. Methods Serum concentration of cTnI was monitored before each treatment and 1 month after the treatment completion. Echocardiography was performed before treatments 1, 3, 5, and 1 month after completion. The EV‐miRNA was isolated and sequenced before treatments 1 and 3, and 1 month after completion. Results Linear mixed model analysis for repeated measurements was used to evaluate the effect of DOX. The miR‐107 (P = .03) and miR‐146a (P = .02) were significantly downregulated whereas miR‐502 (P = .02) was upregulated. Changes in miR‐502 were significant before administration of the third chemotherapeutic dose. When stratifying miRNA expression for change in left ventricular ejection fraction, upregulation of miR‐181d was noted (P = .01). Serum concentration of cTnI changed significantly but only 1 month after treatment completion, and concentrations correlated with left ventricular ejection fraction and left ventricular internal dimension in diastole. Conclusion and Clinical Significance Downregulation of miR‐502 was detected before significant changes in cTnI concentrations or echocardiographic parameters. Further validation using a larger sample size will be required.

Abstract
BACKGROUND Prostate cancer (PCa) is the second most frequent cancer and the fifth leading cause of cancer-related death in men while the mechanisms remain unclear. METHODS Differentially expressed mRNAs (DEmRNAs) and miRNAs (DEmiRNAs) between PCa and non-tumor controls were identified by using microarray analysis. Functional annotation of DEmRNAs, construction of protein-protein interaction (PPI) network and prediction of upstream transcription factors and downstream target DEmRNAs of DEmiRNAs were conducted to further research functions of key DEmRNAs and DEmiRNAs. Validation of selected DEmRNAs and survival analysis were conducted by using The Cancer Genome Atlas (TCGA). RESULTS Total of 91 DEmRNAs and 62 DEmiRNAs were obtained. Thrombospondin-4 precursor (THBS4) was the most significantly up-regulated DEmRNA whose product was predicted to interact with the hub protein of the PCa-specific PPI network, collagen type I alpha 1 chain (COL1A1). Both ATP binding cassette subfamily C member 4 (ABCC4) and endothelin receptor type B (EDNRB) have great prognostic value for PCa. Thrombospondin type 1 domain containing 4 (THSD4) was a down-regulated DEmRNA regulated by several cancer-related miRNAs including has-miR-107, hsa-miR-3175 and hsa-miR-484. Two miRNAs (hsa-miR-428 and hsa-miR-4284) involve in PCa by regulating BMP5-BAMBI interaction and TGF-beta signaling pathway. The expression of selected DEmRNAs between PCa and non-tumor controls in TCGA was consistent with that in our microarray analysis, generally. CONCLUSIONS Key DEmRNAs and DEmiRNAs between PCa and non-tumor controls were identified in this study which provided clues for exploring the molecular mechanism and developing potential biomarkers and therapeutic target sites for PCa.

Abstract
PURPOSE To investigate the effect of miR-107 on the growth and metastasis of gastric cancer (GC) and elucidate the probable mechanisms. METHODS The expression of miR-107 and FAT4 in GC tissues and cells were detected using qRT-PCR. Bioinformatics and dual luciferase reporter gene assays were used to analyze the relationship between miR-107 and FAT4. miR-NC, miR-107 inhibitor, pcDNA3.1-FAT4 and siRNA-FAT4 were transfected into AGS and MKN-45 GC cell lines, respectively. The proliferation and migration abilities of GC cells after transfection were evaluated using the MTT assay, scratch test and transwell assay. The expression of epithelial-mesenchymal transition (EMT) markers: E-cadherin, N-cadherin, vimentin and related proteins of the PI3K/AKT signaling pathway were determined using western blot. The xenograft tumors of nude mice were observed to assess the tumorigenicity of GC cells in vivo. RESULTS MiR-107 was up-regulated, while FAT4 was down-regulated in GC tissues and cells (P < 0.05); FAT4 was targeted and negatively regulated by miR-107. Down-regulating miR-107 or up-regulating FAT4 inhibited the GC cells proliferation, migration, invasion and tumorigenicity, and could also reduce the expression of N-cadherin, vimentin, p-PI3K and p-Akt expression and up-regulate E-cadherin. CONCLUSIONS miR-107 promotes growth and metastasis in GC via activation of PI3K-AKT signaling by targeting FAT4, which may be a target for GC treatment.

Abstract
Background While microRNAs (miRNAs) are known to play a critical role in the progression of colorectal cancer, the role of miR-107 remains unknown. We evaluated its role and explored the underlying mechanism. Materials & methods MTT, wound-healing, transwell migration and transwell invasion assays were performed to evaluate the role of miR-107 in SW629 cell proliferation, migration and invasion. Real time-PCR and dual-luciferase reporter gene, TFR1 overexpression and western blotting assays were used to explore the underlying mechanism. Results MiR-107 is downregulated in colorectal cancer tissues and several human colorectal cancer cell lines. Low miR-107 expression often indicates a poor survival rate for colorectal cancer patients. MiR-107 suppresses the proliferation, migration and invasion of SW620 cells by negatively regulating transferrin receptor 1 (TFR1). Conclusion MiR-107 suppresses the metastasis of colorectal cancer and could be a potential therapy target in colorectal cancer patients.

Abstract
PURPOSE To investigate the effects of microRNAs-107 (miR-107) on autophagy, proliferation, and migration of breast cancer cells and its mechanism by targeting high mobility group protein B1 (HMGB1). METHODS Real-time polymerase chain reaction assay was used to detect the expression of miR-107 in breast cancer and its cell lines. In MDA-MB-231 and MDA-MB-453 breast cancer cells, the expression of p62, Beclin1 protein, and the changes of cell proliferation and migration after overexpression of m miR-107 were detected by Western blotting, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, and transwell assays. Target Scan online prediction, dual luciferase reporter gene, and Western blot were used to verify the targeting relationship between miR-107 and HMGB1. The effects of silencing HMGB1 expression on p62, Beclin1 protein expression, cell proliferation, and migration ability were detected. The transfected MDA-MB-453 cells were inoculated into the right axilla of the nude mice, the tumor volume and weight were weighed, and the expression of miR-107, HMGB1, p62, and Beclin1 in the tumor were detected. RESULTS The expression of miR-107 was downregulated in breast cancer tissues and cell lines (P < 0.01). The expression of p62 protein was upregulated (P < 0.01), while Beclin1 protein was downregulated (P < 0.01) and cell proliferation and migration ability were decreased (P < 0.01) after overexpressing miR-107 in MDA-MB-231 and MDA-MB-453 cells. The results of TargetScan online prediction, dual luciferase reporter gene, and Western blot showed that miR-107 could regulate HMGB1 expression. The expression of p62 protein was upregulated (P < 0.01), while Beclin1 protein was downregulated (P < 0.01) and cell proliferation and migration ability were decreased (P < 0.01) after silencing HMGB1 in MDA-MB-231 and MDA-MB-453 cells. The results of xenograft experiments showed that miR-107 could delay tumor growth and inhibit autophagy. CONCLUSION miR-107 could inhibit cell autophagy, proliferation, and migration of breast cancer cells by targeting HMGB1.

Shen L, Hu Y, Lou J, Yin S, Wang W, Wang Y, Xia Y, Wu W. CircRNA‑0044073 is upregulated in atherosclerosis and increases the proliferation and invasion of cells by targeting miR‑107. Mol Med Rep 2019; 19:3923-3932. [PMID: 30864721 DOI: 10.3892/mmr.2019.10011] [Citation(s) in RCA: 43] [Impact Index Per Article: 8.6] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2018] [Accepted: 09/13/2018] [Indexed: 11/05/2022] Open
Abstract
Circular RNAs (circRNAs) are endogenous non‑coding RNAs implicated in atherosclerosis. The aim of the present study was to explore the function of circRNA‑0044073 in atherosclerosis. Reverse transcription quantitative polymerase chain reaction assays were used to measure the expression levels of circRNA‑0044073, microRNA (miRNA/miR)‑107, janus kinase 1 (JAK1), signal transducer and activator of transcription 3 (STAT3), B‑cell lymphoma 2 (Bcl‑2) and v‑myc avian myelocytomatosis viral oncogene homolog (c‑myc) in in blood cells from patients with atherosclerosis. RNA pull‑down and luciferase reporter assays were then used to determine the association between circRNA and miR expression, and miR and gene expression, respectively. Matrigel invasion assay and flow cytometry were used to analyze cell invasion and cell cycle. Western blot analysis and ELISA were used to evaluate the expression levels of proteins. It was identified that the expression of circRNA‑0044073 was upregulated and the expression of miR‑107 was downregulated in atherosclerotic blood cells. Overexpression of circRNA‑0044073 promoted the proliferation of human vascular smooth muscle cells (HUVSMCs) and human vascular endothelial cells (HUVECs), while overexpression of miR‑107 inhibited their proliferation. In addition, circRNA‑0044073 suppressed the levels of miR‑107 via a sponge mechanism. Lipopolysaccharide (LPS) affected the proliferation of HUVSMCs and HUVECs, and also resulted in changes in circRNA‑0044073 expression levels. CircRNA‑0044073 promoted the proliferation and invasion of HUVSMCs and HUVECs in spite of the opposite effect observed with LPS treatment. The JAK/STAT signaling pathway was activated in patients with atherosclerosis. CircRNA‑0044073 favored the activation of the JAK/STAT signaling pathway and inflammation in HUVSMCs and HUVECs. These data indicate that circRNA‑0044073 is upregulated in atherosclerosis and promotes the proliferation and invasion of cells by targeting miR‑107 and activating the JAK/STAT signaling pathway, potentially offering a target for novel treatment strategies against atherosclerosis.

Abstract
Abstract
The present study aims to determine the potential biomarkers and uncover the regulatory mechanisms of the long-noncoding RNA (lncRNA) TINCR/miR-107/CD36 axis in colorectal cancer (CRC). Aberrantly-expressed lncRNAs and differential-expressed genes were identified by analyzing the dataset GSE40967. Gene set enrichment analysis was employed, and Cytoscape software helped in establishing the co-expression network between lncRNAs and genes. Quantitative reverse transcription-polymerase chain reaction (RT-PCR) analysis contributes to examining the expression levels of lncRNA TINCR, miR-107 and CD36. The dual luciferase assay was used to validate the association between miR-107 and lncRNA TINCR or CD36. The EdU incorporation assay was employed, and flow cytometry was employed to detect cell apoptosis with the tumor xenograft model being utilized. Significantly dysregulated lncRNAs and mRNAs were identified. The peroxisome proliferator-activated receptor (PPAR) signaling pathway in CRC tissues was down-regulated. The loss of TINCR expression was associated with CRC progression. The expression levels of the TINCR and CD36 were down-regulated. We identified miR-107 as an inhibitory target of TINCR and CD36. Overexpression of TINCR could inhibit cell proliferation and promote apoptosis. MiR-107 overexpression in CRC cells induced proliferation and impeded apoptosis. A regulatory function of the lncRNA TINCR/miR-107/CD36 axis in CRC was revealed. LncRNA TINCR overexpression exerted suppressive influence on CRC progression through modulating the PPAR signaling pathway via the miR-107/CD36 axis.

[PMID: 30441811 PMCID: PMC6266399 DOI: 10.3390/cancers10110440] [Citation(s) in RCA: 37] [Impact Index Per Article: 6.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2018] [Revised: 11/06/2018] [Accepted: 11/08/2018] [Indexed: 02/06/2023] Open
Abstract
Colorectal cancers have become the second leading cause of cancer-related deaths. In particular, acquired chemoresistance and metastatic lesions occurring in colorectal cancer are a major challenge for chemotherapy treatment. Accumulating evidence shows that long non-coding (lncRNAs) are involved in the initiation, progression, and metastasis of cancer. We here discuss the epigenetic mechanisms through which lncRNAs regulate gene expression in cancer cells. In the second part of this review, we focus on the role of lncRNA Urothelial Cancer Associated 1 (UCA1) to integrate research in different types of cancer in order to decipher its putative function and mechanism of regulation in colorectal cancer cells. UCA1 is highly expressed in cancer cells and mediates transcriptional regulation on an epigenetic level through the interaction with chromatin modifiers, by direct regulation via chromatin looping and/or by sponging the action of a diversity of miRNAs. Furthermore, we discuss the role of UCA1 in the regulation of cell cycle progression and its relation to chemoresistance in colorectal cancer cells.

Abstract
MicroRNAs are short regulatory RNAs that posttranscriptionally modulate gene expression and thus play crucial roles in controlling cancer-onset, growth, and progression processes. miR107, a highly conserved microRNA that maps to intron 5 of the PANK1 gene, contributes to the regulation of normal and tumor biological processes. Studies have reported that miR107 has oncogenic or tumor-suppressor functions in different human tumors. The pleiotropic functions of miR107 in various cancers are achieved via its targeting different genes that are involved in tumor proliferation, invasiveness, metastasis, angiogenesis, and chemotherapy-response pathways. The carcinogenicity or cancer-suppressor effects of miR107 occur in a tissue- and cell-specific manner, and the expression level of miR107 can be affected by various factors, including epigenetic and genetic factors, treatment exposure, and daily diet. A comprehensive analysis of the current literature suggests that miR107 functions as a central element in the regulation of cancer networks and can be used as a potential diagnostic and prognostic biomarker and drug target for therapeutic intervention.

Abstract
BACKGROUND Colon cancer, one of the most common causes of cancer-related deaths, arises from adenomatous polyps. In these years, circulating microRNAs (miRNAs) have attracted increasing attention as novel biomarkers for colon cancers. The dysregulated circulating miRNAs in patients with colon adenomas has not been well-understood. METHODS Here, we aimed to identify miRNA profile in the serum of patients with colon adenomas or colon cancer by using microarray. Then we validated eight differentially expressed miRNAs (DEMs) by qRT-PCR and predicted their targets. RESULTS We identified 26 DEMs from Adenomas versus Normal comparison (11 up-regulations and 15 down-regulations), 72 DEMs from Cancer versus Normal comparison (19 up-regulations and 53 down-regulations) and 17 DEMs from Cancer versus Adenomas comparison (4 up-regulations and 13 down-regulations). Moreover, three DEMs identified from Cancer versus Normal comparison were included in the list of DEMs identified from Cancer versus Adenomas comparison, and may be specific diagnostic biomarkers for colon cancer. Five down-regulated miRNAs identified from Cancer versus Normal comparison were included in the list of DEMs identified from Adenomas versus Normal comparison, and may be important for the development of colon polyps and cancer. CONCLUSIONS We discovered 8 circulating miRNAs associated with colon adenomas and colon cancer, and these miRNAs may potentially serve as noninvasive screening biomarkers for colon cancer. Our study is useful for expanding our understanding in the development of colon adenomas and colon cancer, and thus provide novel insights into colon cancer pathogenesis and prevention.
