RGS1 targeted by miR-191-3p inhibited the stemness properties of esophageal cancer cells by suppressing CXCR4/PI3K/AKT signaling. Acta Histochem 2024; 126:152190. [PMID: 39173233 DOI: 10.1016/j.acthis.2024.152190] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2024] [Revised: 07/27/2024] [Accepted: 08/15/2024] [Indexed: 08/24/2024]
Abstract
BACKGROUND Esophageal cancer is one of the most common malignant tumors in the world. It is urgent to prevent the development and progression of esophageal cancer. Cancer stem cells (CSCs) were reported to have the ability to initiate tumorigenesis, and reducing the stem cell-like characteristics of tumors is an important strategy to inhibit the occurrence and development of tumors. miRNAs are key regulators of the stemness of cancer. Here, we aimed to investigate the role and regulatory mechanism of miR-191-3p in the stemness properties of esophageal cancer cells. METHODS Esophageal cancer cells with stable expression of miR-191-3p were established by lentivirus system. CCK-8 assay, transwell assay, wound healing assay were used to evaluate the effect of miR-191-3p on proliferation and metastasis of esophageal cancer cells. The expression of stemness-related markers (NANOG, OCT4, SOX2), ALDH activity, sphere-forming assay and subcutaneous tumor model in nude mice were performed to evaluate the stemness properties of esophageal cancer cells in vitro and in vivo. Dual-luciferase reporter assay was used to verify the molecular mechanism. RESULT Here we found that overexpression of miR-191-3p promoted the stemness properties of esophageal cancer cells in vitro and in vivo, including increasing esophageal cancer cell proliferation and metastasis ability, the expression of stemness-related markers NANOG, OCT4, and SOX2, ALDH activity, the number of spheres formed and tumor growth. Bioinformatic analysis and dual-luciferase assay demonstrated that regulator of G protein signaling 1 (RGS1) was the directed target gene of miR-191-3p and attenuated the promotion effect of miR-191-3p on the stemness of esophageal cancer cells. Furthermore, we found that RGS1 knockdown activated the PI3K/AKT pathway by negatively regulating CXCR4 to promote the stemness of esophageal cancer cells. CONCLUSIONS Our findings revealed that RGS1 targeted by miR-191-3p inhibited the stemness of esophageal cancer cells by suppressing the CXCR4/PI3K/AKT pathway, which provide potential prognostic markers and therapeutic targets in the future.

Expert Rev Clin Immunol 2024; 20:913-926. [PMID: 38712535 DOI: 10.1080/1744666x.2024.2352484] [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: 12/06/2023] [Accepted: 05/03/2024] [Indexed: 05/08/2024]
Abstract
INTRODUCTION Vasculogenic mimicry (VM) alludes to the ability of cancer cells to organize on three-dimensional channel-like structures to obtain nutrients and oxygen. This mechanism confers an aggressive phenotype, metastatic potential, and resistance to chemotherapy resulting in a poor prognosis. Recent studies have been focused on the identification of microRNAs (miRNAs) that regulate the VM representing potential therapeutic targets in cancer. AREAS COVERED An overview of the roles of miRNAs on VM development and their functional relationships with tumor microenvironment. The functions of cancer stem-like cells in VM, and resistance to therapy are also discussed. Moreover, the modulation of VM by natural compounds is explored. The clinical significance of deregulated miRNAs as potential therapeutic targets in tumors showing VM is further highlighted. EXPERT OPINION The miRNAs are regulators of protein-encoding genes involved in VM; however, their specific expression signatures with clinical value in large cohorts of patients have not been established yet. We considered that genomic profiling of miRNAs could be useful to define some hallmarks of tumors such as stemness, drug resistance, and VM in cancer patients. However, additional studies are needed to establish the relevant role of miRNAs as effective therapeutic targets in tumors that have developed VM.

Mechanism of gambogic acid repressing invasion and metastasis of colorectal cancer by regulating macrophage polarization via tumor cell-derived extracellular vesicle-shuttled miR-21. Drug Dev Res 2024; 85:e22141. [PMID: 38349264 DOI: 10.1002/ddr.22141] [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: 08/03/2023] [Revised: 11/29/2023] [Accepted: 12/11/2023] [Indexed: 02/15/2024]
Abstract
Colorectal cancer (CRC) is a major cause of mortality and morbidity. Gambogic acid (GA) is a promising antitumor drug for treating CRC. We aimed to elucidate its mechanism in CRC invasion/metastasis via tumor cell-derived extracellular vesicle (EV)-carried miR-21. Nude mice peritoneal carcinomatosis (PC) model was subjected to GA treatment liver collection, followed by observation/counting of metastatic liver tissues/liver metastatic nodules by hematoxylin and eosin staining. miR-21 expression in metastatic liver tissues/CD68 + CD86, CD68 + CD206 cell percentages and M2 macrophage marker CD206 level in tumor tissues/interleukin (IL)-12 and IL-10 levels were determined by reverse transcription-quantitative polymerase chain reaction (RT-qPCR)/flow cytometry/enzyme-linked immunosorbent assay. HT-29 cells were treated with GA/miR-21 mimics/negative control for 48 h. miR-21 expression/cell proliferation/migration/invasion/apoptosis were assessed by RT-qPCR/cell counting kit-8/scratch assay/transwell assay/flow cytometry. EVs were extracted from HT-29 cells and identified by transmission electron microscope/nanoparticle tracking analysis/Western blot. IL-4/IL-13-induced macrophages/PC nude mice were treated with GA and EVs, with the internalization of EVs by macrophages assessed through the uptake test. After intraperitoneal injection of GA, PC nude mice exhibited decreased tumor cell density/irregular cell number/liver metastatic nodule number/miR-21 expression, and CRC cells manifested reduced CD68 + CD206 cells/IL-10/miR-21/proliferation/migration/invasion and increased CD68 + CD86 cells/IL-12/apoptosis, while these trends were opposite after miR-21 overexpression, implying that GA curbed CRC/cell invasion/metastasis and macrophage polarization by diminishing miR-21 levels. miR-21 was encapsulated in HT-29 cell-derived EVs. M2 polarization elevated CD206 cells/IL-10, which were decreased by simultaneous GA treatment. EVs could be uptaken by macrophages. CRC cell-EV-miR-21 annulled the suppression effects of GA on macrophage M2 polarization. GA suppressed macrophage M2 polarization by lessening tumor cell derived-EV-shuttled miR-21, thereby weakening CRC invasion/metastasis.

Abstract
Colorectal cancer (CRC) is among the leading causes of cancer mortality. The lifetime risk of developing CRC is about 5% in adult males and females. CRC is usually diagnosed at an advanced stage, and at this point therapy has a limited impact on cure rates and long-term survival. Novel and/or improved CRC therapeutic options are needed. The involvement of microRNAs (miRNAs) in cancer development has been reported, and their regulation in many oncogenic pathways suggests their potent tumor suppressor action. Although miRNAs provide a promising therapeutic approach for cancer, challenges such as biodegradation, specificity, stability and toxicity, impede their progression into clinical trials. Nanotechnology strategies offer diverse advantages for the use of miRNAs for CRC-targeted delivery and therapy. The merits of using nanocarriers for targeted delivery of miRNA-formulations are presented herein to highlight the role they can play in miRNA-based CRC therapy by targeting different stages of the disease.

Abstract
BACKGROUND Aberrant expression of miRNAs have been implicated in cancers, but the role of miRNAs in colorectal cancer (CRC) remains need to be elucidated. This study aimed to identify miRNAs that related to colorectal cancer (CRC) pathogenesis and determine the diagnostic value. METHODS Three GEO datasets (GSE128449, GSE35602 and GSE49246) with 131 samples were used to screen miRNAs that differential expression between tumor and control tissues. The expression of the identified miRNAs was validated in 50 clinical tissue samples and the GSE35834 dataset. The clinical significance of these miRNAs was analyzed in the TCGA dataset and clinical tissue samples. The expression of miRNAs in tissues and plasma samples were tested by RT-PCR assay in clinical samples, and their diagnostic value was determined. RESULTS The analysis of three GEO datasets revealed that miR-595 and miR-1237 were upregulated, while miR-126, miR-139, and miR-143 were downregulated in CRC tissues compared to control tissues. The differential expression of the five miRNAs in CRC tissues was confirmed using clinical tissue samples and GEO databases. There was no significant correlation between the TNM stage and tumor stage of CRC and any of the five miRNAs. Plasma expression of the miRNAs differed significantly between CRC and non-cancer patients, and each miRNA had moderate diagnostic value for CRC. Combining the five miRNAs provided better diagnostic potential for CRC than a single miRNA. CONCLUSIONS This study demonstrated that five miRNAs were related to the pathogenesis of CRC, but independent of the stage of CRC; Plasma expression of these miRNAs have moderate diagnostic value, and combination of these miRNAs showed better diagnostic ability in CRC.

Abstract
Cardiac fibrosis is a cause of morbidity and mortality in people with heart disease. Anti-fibrosis treatment is a significant therapy for heart disease, but there is still no thorough understanding of fibrotic mechanisms. This study was carried out to ascertain the functions of cytokine receptor-like factor 1 (CRLF1) in cardiac fibrosis and clarify its regulatory mechanisms. We found that CRLF1 was expressed predominantly in cardiac fibroblasts. Its expression was up-regulated not only in a mouse heart fibrotic model induced by myocardial infarction, but also in mouse and human cardiac fibroblasts provoked by transforming growth factor-β1 (TGF-β1). Gain- and loss-of-function experiments of CRLF1 were carried out in neonatal mice cardiac fibroblasts (NMCFs) with or without TGF-β1 stimulation. CRLF1 overexpression increased cell viability, collagen production, cell proliferation capacity, and myofibroblast transformation of NMCFs with or without TGF-β1 stimulation, while silencing of CRLF1 had the opposite effects. An inhibitor of the extracellular signal-regulated kinase 1/2 (ERK1/2) signaling pathway and different inhibitors of TGF-β1 signaling cascades, comprising mothers against decapentaplegic homolog (SMAD)-dependent and SMAD-independent pathways, were applied to investigate the mechanisms involved. CRLF1 exerted its functions by activating the ERK1/2 signaling pathway. Furthermore, the SMAD-dependent pathway, not the SMAD-independent pathway, was responsible for CRLF1 up-regulation in NMCFs treated with TGF-β1. In summary, activation of the TGF-β1/SMAD signaling pathway in cardiac fibrosis increased CRLF1 expression. CRLF1 then aggravated cardiac fibrosis by activating the ERK1/2 signaling pathway. CRLF1 could become a novel potential target for intervention and remedy of cardiac fibrosis.

Progression. Clin Med Insights Oncol 2022; 16:11795549221137399. [PMCID: PMC9716453 DOI: 10.1177/11795549221137399] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2022] [Accepted: 10/20/2022] [Indexed: 12/05/2022] Open
Abstract
Background: Colorectal cancer (CRC) has a high prevalence and poor prognosis. This study
aimed to identify biomarkers related to the clinical stage (I-IV) of
CRC. Methods: The LinkedOmics database was used as the discovery cohort, and two Gene
Expression Omnibus (GEO) databases (GSE41258 and GSE422848) served as
validation cohorts. The trend test of genes related to clinical stage (I-IV)
of CRC patients was identified by the Jonckheere-Terpstra test. The
cBioPortal database, Gene Expression Profiling Interactive Analysis (GEPIA)
and PrognoScan databases were used to explore the expression change and
prognostic value of clinical stage-related genes in CRC patients. CRC cells
overexpressed AGPAT5 were constructed and used for cell counting kit-8
(CCK-8), flow cytometric, and wound healing assays in vitro. Results: We identified four clinical stage-related genes, GSR, AGPAT5, CRLF1, and
NPR3, in CRC. The CNA frequencies of GSR, CRLF1, AGPAT5, and NPR3 occurred
in 11%, 2.4%, 13%, and 3% of patients, respectively. The expression of GSR
and AGPAT5 tended to decrease with CRC stage (I-IV) progression, and the
expression of CRLF1 and NPR3 tended to increase with CRC stage (I-IV)
progression. Compared with the normal group, AGPAT5 expression was markedly
decreased in stage IV CRC. Higher GSR and AGPAT5 expression levels were
associated with better overall survival (OS) and disease-free survival (DFS)
in CRC patients. Lower CRLF1 and NPR3 expression levels were associated with
better OS and DFS in CRC. GSR, CRLF1, AGPAT5, and NPR3 expression were
related to CRC progression, microsatellite instability, and tumour purity in
CRC. Furthermore, AGPAT5 was downregulated in CRC cell lines, and
overexpression of AGPAT5 inhibited cell proliferation and migration and
promoted cell apoptosis in CRC cells. Conclusion: Low AGPAT5 expression may serve as a poor prognostic factor and clinical
stage biomarker in CRC. In addition, AGPAT5 acts as a tumour suppressor in
CRC progression.

Dicer-mediated miR-200b expression contributes to cell migratory/invasive abilities and cancer stem cells properties of breast cancer cells. Aging (Albany NY) 2022; 14:6520-6536.

Abstract
Distant metastasis is the leading cause of death in patients with breast cancer. Despite considerable treatment advances, the clinical outcomes of patients with metastatic breast cancer remain poor. CSCs can self-renew, enhancing cancer progression and metastasis. Dicer, a microRNA (miRNA) processing–related enzyme, is required for miRNA maturation. Imbalanced Dicer expression may be pivotal in cancer progression. However, whether and how Dicer affects the stemness of metastatic breast cancer cells remains unclear. Here, we hypothesized that Dicer regulates the migration, invasion, and stemness of breast cancer cells. We established highly invasive cell lines (MCF-7/I-3 and MDA-MB-231/I-3) and observed that Dicer expression was conspicuously lower in the highly invasive cells than in the parental cells. The silencing of Dicer significantly enhanced the cell migratory/invasive abilities and CSCs properties of the breast cancer cells. Conversely, the overexpression of Dicer in the highly invasive cells reduced their migration, invasion, and CSCs properties. Our bioinformatics analyses demonstrated that low Dicer levels were correlated with increased breast cancer risk. Suppression of Dicer inhibited miR-200b expression, whereas miR-200b suppression recovered Dicer knockdown–induced migration, invasion, and cancer stem cells (CSCs) properties of the breast cancer cells. Thus, our findings reveal that Dicer is a crucial regulator of the migration, invasion, and CSCs properties of breast cancer cells and is significantly associated with poor survival in patients with breast cancer.

Abstract
The present study focused on identifying the immune-related signatures and exploring their performance in predicting the prognosis, immunotherapeutic responsiveness, and diagnosis of patients with colon cancer. Firstly, the immunotherapeutic response-related differential expressed genes (DEGs) were identified by comparing responders and non-responders from an anti-PD-L1 cohort using the edgeR R package. Then, the immunotherapeutic response related DEGs was intersected with immune-related genes (IRGs) to obtain the immunotherapeutic response and immune-related genes (IRIGs). Then, an immunotherapeutic response and immune-related risk score (IRIRScore) model consisting of 6 IRIGs was constructed using the univariable Cox regression analysis and multivariate Cox regression analysis based on the COAD cohort from the cancer genome atlas (TCGA) database, which was further validated in two independent gene expression omnibus database (GEO) datasets (GSE39582 and GSE17536) and anti-PD-L1 cohort. A nomogram with good accuracy was established based on the immune-related signatures and clinical factors (C-index = 0.75). In the training dataset and GSE39582, higher IRIRScore was significantly associated with higher TMN and advanced pathological stages. Based on the anti-PD-L1 cohort, patients who were sensitive to immunotherapy had significantly lower risk score than non-responders. Furthermore, we explored the immunotherapy-related signatures based on the training dataset. Kaplan-Meier curve revealed a high level of T cells regulatory (Tregs) was significantly related to poor overall survival (OS), while a high level of T cells CD4 memory resting was significantly related to better OS. Besides, the TMB value of patients in the high-risk group was significantly higher than those in a low-risk group. Moreover, patients in the high-risk group had significantly higher expression levels of immune checkpoint inhibitors. In addition, the immune-related signatures were applied to establish prediction models using the random forest algorithm. Among them, TDGF1 and NRG1 revealed excellent diagnostic predictive performance (AUC >0.8). In conclusion, the current findings provide new insights into immune-related immunotherapeutic responsiveness, prognosis, and diagnosis of colon cancer.

Front Genet 2022; 13:825318. [PMID: 35154284 PMCID: PMC8829120 DOI: 10.3389/fgene.2022.825318] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2021] [Accepted: 01/10/2022] [Indexed: 01/22/2023] Open
Abstract
Identifying cancer-related miRNAs (or microRNAs) that precisely target mRNAs is important for diagnosis and treatment of cancer. Creating novel methods to identify candidate miRNAs becomes an imminent Frontier of researches in the field. One major obstacle lies in the integration of the state-of-the-art databases. Here, we introduce a novel method, MIMRDA, which incorporates the miRNA and mRNA expression profiles for predicting miRNA-disease associations to identify key miRNAs. As a proof-of-principle study, we use the MIMRDA method to analyze TCGA datasets of 20 types (BLCA, BRCA, CESE, CHOL, COAD, ESCA, HNSC, KICH, KIRC, KIRP, LIHC, LUAD, LUSC, PAAD, PRAD, READ, SKCM, STAD, THCA and UCEC) of cancer, which identified hundreds of top-ranked miRNAs. Some (as Category 1) of them are endorsed by public databases including TCGA, miRTarBase, miR2Disease, HMDD, MISIM, ncDR and mTD; others (as Category 2) are supported by literature evidences. miR-21 (representing Category 1) and miR-1258 (representing Category 2) display the excellent characteristics of biomarkers in multi-dimensional assessments focusing on the function similarity analysis, overall survival analysis, and anti-cancer drugs’ sensitivity or resistance analysis. We compare the performance of the MIMRDA method over the Limma and SPIA packages, and estimate the accuracy of the MIMRDA method in classifying top-ranked miRNAs via the Random Forest simulation test. Our results indicate the superiority and effectiveness of the MIMRDA method, and recommend some top-ranked key miRNAs be potential biomarkers that warrant experimental validations.

Abstract
Cytokines and their receptors have a vital function in regulating various processes such as immune function, inflammation, haematopoiesis, cell growth and differentiation. The interaction between a cytokine and its specific receptor triggers intracellular signalling cascades that lead to altered gene expression in the target cell and consequent changes in its proliferation, differentiation, or activation. In this review, we highlight the role of the soluble type I cytokine receptor CRLF1 (cytokine receptor-like factor-1) and the Interleukin (IL)-6 cytokine CLCF1 (cardiotrophin-like cytokine factor 1) during development in physiological and pathological conditions with particular emphasis on Crisponi/cold-induced sweating syndrome (CS/CISS) and discuss new insights, challenges and possibilities arising from recent studies.
