[PMID: 39133165 PMCID: PMC11346793 DOI: 10.18632/aging.206059] [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: 01/24/2024] [Accepted: 07/16/2024] [Indexed: 08/13/2024]
Abstract
OBJECTIVE Colon cancer is a common malignant tumor of the gastrointestinal system, which is characterized by high morbidity and mortality. The purpose of this study was to analyze the expression and biological role of miR-181a-2-3p in colon cancer and to investigate the molecular mechanism of its regulatory effect on colon cancer through stimulator of interferon genes (STING). METHODS Real-time reverse transcription polymerase chain reaction (qRT-PCR) assay was used to detect the expression of miR-181a-2-3p in colon cancer cell lines and normal intestinal epithelial cells. After overexpression of miR-181a-2-3p in colon cancer cell lines SW480 and HT29, cells were examined by CCK8, Transwell, and flow cytometry assays for alterations in proliferation, migration, apoptosis, and cell cycle. Target genes of miR-181a-2-3p were predicted by bioinformatics and validated by dual luciferase assays. Rescue experiments were performed to explore the role of STING in the effect of miR-181a-2-3p. The effect of miR-181a-2-3p on colon cancer proliferation in vivo was validated by nude mouse tumorigenicity assay. RESULTS miR-181a-2-3p was lowly expressed in both colon cancer tissues and cell lines. Overexpression of miR-181a-2-3p led to reduced proliferation and migration, increased apoptosis, and altered cell cycle in colon cancer cell lines SW480 and HT29. STING was a target gene of miR-181a-2-3p. Increased STING expression partially counteracted the effect of overexpression of miR-181a-2-3p on colon cancer cell lines. miR-181a-2-3p also suppressed colon cancer proliferation in vivo. CONCLUSION miR-181a-2-3p inhibits the proliferation and oncogenicity of colon cancer, and its molecular mechanism could be inhibited by STING.

Abstract
Colon cancer (CC) is a tumor of the large intestine. miR-92b-3p is often deregulated in the tumorigensis. Here, the role of miR-92b-3p in the development of CC was investigated. miR-92b-3p and Kruppel-like factor 3 (KLF3) expression was examined in CC tissues and cells. miR-92b-3p inhibitor or KLF3 overexpression vector was transfected into CC cells, respectively to observe its role in CC cell proliferation, invasion, migration, and apoptosis. The targeting relationship between miR-92b-3p and KLF3 was validated. Meanwhile, rescue experiments were performed by co-transfection of miR-92b-3p inhibitor and KLF3 siRNA, followed by determining CC cell proliferation, invasion, migration, and apoptosis. Higher miR-92b-3p and lower KLF3 expression levels were observed in CC tissues and cells. miR-92b-3p inhibition or KLF3 overexpression reduced proliferation, invasion, and migration whereas induced apoptosis of CC cells. KLF3 was validated to be the target gene of miR-92b-3p. Depletion of KLF3 could reverse the antitumor role of miR-92b-3p inhibition in CC cells. miR-92b-3p augments CC development through inhibiting KLF3, which may confers a novel way to develop future treatment target.

Abstract
MiRNAs are short stranded single non-coding oligonucleotides that play an important role in regulating gene expression. MiRNAs are stable in RNase enriched environments such as human body fluids and their dysregulation or abnormal abundance in human body fluids as a diagnostic biomarker has been associated with several diseases. Due to the low concentration of miRNAs, it is difficult to detect using interactive methods (ideal detection limit is femtomolar range). However, clinicians lack sensitive and reliable methods for quantifying miRNA. Microfluidic devices integrated with electrochemical, optical (fluorometric, SERs, FRET, colorimetric), electrochemiluminescence and photoelectrochemical signal readout led to development innovative diagnostic device test, can probably overcome the limitations of the traditional methods. In the present review, microfluid methods for the sensitive and selective recognition of miRNA in various biological matrices are surveyed. Also, advantages and limitation of recognition methods on the performance and efficiency of microfluidic based biosensing of miRNAs are critically investigated. Finally, the future perspectives on the diagnosis of disease based on microfluidic analysis of miRNAs are provided.

miR-1266-3p Suppresses Epithelial-Mesenchymal Transition in Colon Cancer by Targeting P4HA3. Anal Cell Pathol (Amst) 2022; 2022:1542117. [PMID: 35433237 PMCID: PMC9010195 DOI: 10.1155/2022/1542117] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2021] [Accepted: 03/19/2022] [Indexed: 12/13/2022] Open
Abstract
Numerous studies have been conducted to demonstrate that miRNA is strongly related to colon cancer progression. Nevertheless, there are few studies regarding the function for miR-1266-3p in colon cancer, and the molecular mechanism remains poorly know. Our study was designed to examine the level of miR-1266-3p expression among the colon cancer tissue and cell and to study the role and regulatory mechanism for miR-1266-3p among colon cancer's malignant biologic behavior. First, we found that miR-1266-3p expression was distinctly lower in colonic carcinoma tissues and cells than in nontumor ones, and the prognosis of low miR-1266-3p patients was distinctly worse than that of high miR-1266-3p patients. Second, we predicted that the target gene of miR-1266-3p was prolyl 4-hydroxylase subunit alpha 3 (P4HA3) through bioinformatics, and the targeting relationship between the two was verified by a dual luciferase assay report. Furthermore, miR-1266-3p inhibited the growth and metastasis of colon cancer in vitro as well as in vivo, and this effect could be alleviated by overexpressing P4HA3. Even more importantly, our study demonstrated that miR-1266-3p inhibited epithelial-mesenchymal transition (EMT) by targeting P4HA3. In conclusion, miR-1266-3p could inhibit growth, metastasis, and EMT in colon cancer by targeting P4HA3. Our discoveries might offer a novel target for colon cancer diagnosis and treatment.

Evaluation of miR-330-3p and BMI1 Expression in Colorectal Cancer Patients, Healthy Adjacent Tissues, and Polypoid Adenomatous Lesions. INTERNATIONAL JOURNAL OF MOLECULAR AND CELLULAR MEDICINE 2022; 11:334-345. [PMID: 37727645 PMCID: PMC10506674 DOI: 10.22088/ijmcm.bums.11.4.334] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/11/2022] [Revised: 05/17/2023] [Accepted: 07/15/2023] [Indexed: 09/21/2023]
Abstract
MicroRNAs (miRNAs) have emerged as essential gene expression regulators associated with human diseases such as colorectal cancer (CRC). The purpose of this study was to evaluate the expression of miR-330-3p and its target gene BMI1 in tissue samples of patients with CRC, polyp, and healthy adjacent tissue samples and their association with clinicopathological and demographic factors such as age, tumor stage, grade, and lymph node invasion of the tumor. Following the extraction of total RNA from approximately 50 mg of colon and rectum tissue of 82 patients with CRC, 13 polypoid lesions, and 26 marginal healthy tissues using RiboEx reagent, cDNA synthesis was performed, and then quantitative real-time PCR was used to detect the expression levels of miR-330-3p and BMI1. Alterations in the gene expression were assessed using the 2(-∆∆ CT) method. The expression of miR-330-3p in all of the CRC samples was significantly lower than in adjacent healthy tissues and polyp (P<0.001). BMI1 was up-regulated in 97.9% of CRC tissue compared to healthy adjacent tissues and polyps (P<0.001). A negative reverse correlation between the miR-330-3p and BMI1 gene was observed in the CRC samples (r= -0.882, P<0.001). Down-regulation of miR-330-3p and BMI1 overexpression strongly correlates with higher tumor stage and lymph node invasion. The AUC for miR-330-3p and BMI1expression was 0.982 (sensitivity, 98.5%; specificity, 78.8%), and 0.971 (sensitivity, 97.6%; specificity, 84.6%) (P<0.001), respectively. Our results indicated that miR-330-3p and BMI1 expression probably could be considered potential diagnostic or prognostic biomarkers for CRC patient.

Abstract
Aim: To investigate the effects of SKA3 on cell proliferation and metastasis in non-small-cell lung cancer (NSCLC) and its underlying mechanism. Methods: Immunohistochemistry was employed to analyze the expression of SKA3 in NSCLC. CCK-8 assay, EdU assay, Transwell assay and flow cytometry analysis were employed to assess cell proliferation, metastatic potential and apoptosis in vitro, respectively. A lung metastasis model was used to evaluate metastasis of NSCLC cells in vivo. A luciferase reporter gene assay was conducted to verify the targeting relationship. Results: SKA3 exhibited high expression in NSCLC tissues and cells. Overexpression of SKA3 remarkably accelerated cell proliferation and metastasis and suppressed apoptosis of NSCLC cells and promoted lung metastasis in a mouse model. miR-128-3p repressed SKA3 expression by targeting it. Conclusion: miR-128-3p inhibited the progression of NSCLC through targeting SKA3.

Abstract
Hepatocellular carcinoma (HCC) has a high dead rate partly due to late diagnosis. This study aimed to investigate the prognostic value of miR-937 in HCC and its role in the HCC progression. HCC tissue and adjacent non-cancerous tissues (NCT) (n = 125) were detected about the expression level of miR-937 via real-time quantitative PCR. The relationship between miR-937 expression and each important clinical characteristic was evaluated. And the prognostic significance of miR-937 was assessed by Kaplan-Meier curve and Cox regression analysis. CCK-8 and Transwell assays were conducted to observe the effects of miR-937 on HCC cell proliferation, migration, and invasion. The miR-937 expression was upregulated in HCC tissues, as well as in HCC cell lines. The upregulation of miR-937 showed a significant association with lymph node metastasis and TNM stage. Upregulation of miR-937 predicted poor prognosis of HCC patients. Overexpression of miR-937 promoted HCC cell ability of proliferation, migration, and invasiveness, while knockdown of miR-937 inhibited these cellular behaviors. miR-937 expression was upregulated in HCC and may serve as a promising prognostic factor and treated target for HCC patients. miR-937 might exert a promoter role in HCC through accelerated tumor cell proliferation, migration, and invasion.

Cell Signal 2020; 77:109818. [PMID: 33144185 DOI: 10.1016/j.cellsig.2020.109818] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2020] [Revised: 09/25/2020] [Accepted: 10/22/2020] [Indexed: 12/18/2022]
Abstract
Breast cancer is one of the most frequent cancers in women and the globally leading cause of cancer-related deaths. Bioinformatics and experimental analyses found that miR-937-5p may play a proto-oncogenic role in breast cancer; however, the specific effects and the molecular mechanism need further investigation. GSEA-KEGG and GSEA-GO suggested that miR-937-5p might be related to cell cycle and DNA replication. The experimental data indicated that miR-937-5p inhibition significantly repressed the proliferation of breast carcinoma cells and elicited S-phase cell cycle arrest. Meanwhile, the protein levels of proliferating marker ki-67 and cell cycle regulators Cyclin A2, Cyclin B1, CDK1, and Cyclin D1 were also decreased by miR-937-5p inhibition. miR-937-5p could directly bind to and negatively regulate SOX17. SOX17 overexpression also significantly repressed the proliferation of breast carcinoma cells and elicited S-phase cell cycle arrest and decreased ki-67, β-catenin, c-Myc, Cyclin A2, Cyclin B1, Cyclin D1, and CDK1 protein contents. More importantly, the effects of miR-937-5p were reversed by SOX17.
