Abstract
Prostate cancer (PCa) has become the most frequently occurring cancer among western men according to the latest report, and patients’ prognosis is often poor in the event of tumor progression, therefore, many researches are devoted to exploring the molecular mechanism of PCa metastasis. MicroRNAs (miRNA) have proved to play an important role in this process. In present study, by combining clinical samples with public databases, we found that miR-629-5p increased to varying degrees in primary localized PCa tissues and metastatic PCa tissues compared with adjacent normal tissues, and bioinformatics analysis suggested that high level of miR-629-5p was related to poor prognosis. Functionally, miR-629-5p drove PCa cell proliferation, migration and invasion in vitro, and promoted growth of PCa cells in vivo. Moreover, A-kinase Anchor Protein 13 (AKAP13) was screened as a direct target of miR-629-5p, that expression was negatively correlated with the malignant phenotype of tumor cells. In the end, through verification in clinical specimens, we found that AKAP13 could be independently used as a clinical prognostic indicator. Overall, the present study indicates that miR-629-5p plays an oncogenic role in PCa by targeting AKAP13, which provides a new idea for clinical diagnosis and treatment of complex refractory PCa.

Gao C, Gao J, Zeng G, Yan H, Zheng J, Guo W. MicroRNA-629-5p promotes osteosarcoma proliferation and migration by targeting caveolin 1. ACTA ACUST UNITED AC 2021; 54:e10474. [PMID: 33886809 PMCID: PMC8055186 DOI: 10.1590/1414-431x202010474] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2020] [Accepted: 12/15/2020] [Indexed: 12/16/2022]
Abstract
Osteosarcoma is a highly malignant tumor that occurs in the bone. Previous studies have shown that multiple microRNAs (miRNAs) regulate the development of osteosarcoma. This study aimed to explore the role of miR-629-5p and its target gene, caveolin 1 (CAV1), in osteosarcoma development. To analyze the expression of miR-629-5p and CAV1 mRNA in osteosarcoma tissues and cell lines, qRT-PCR analysis was performed. Dual-luciferase reporter experiments were subsequently performed to validate the relationship between CAV1 and miR-629-5p. CCK8 assay was used to measure osteosarcoma cell proliferation, and wound-healing assay was performed to study their migratory phenotype. Our findings revealed that miR-629-5p was overexpressed in osteosarcoma tissues and cells, and thereby enhanced cell proliferation and migration. Further, we validated that miR-629-5p targets CAV1 mRNA directly. CAV1 expression, which was negatively correlated with miR-629-5p expression, was found to be downregulated in osteosarcoma tissue samples. Moreover, our data showed that an increase in CAV1 level led to a decline in osteosarcoma cell proliferation and migration, which could be rescued by miR-629-5p upregulation. Overall, our study confirmed that miR-629-5p promoted osteosarcoma proliferation and migration by directly inhibiting CAV1.

Abstract
Globally, breast cancer is the most frequently diagnosed cancer in women, and it remains a substantial clinical challenge due to cancer relapse. The presence of a subpopulation of dormant breast cancer cells that survived chemotherapy and metastasized to distant organs may contribute to relapse. Tumor microenvironment (TME) plays a significant role as a niche in inducing cancer cells into dormancy as well as involves in the reversible epithelial-to-mesenchymal transition (EMT) into aggressive phenotype responsible for cancer-related mortality in patients. Mesenchymal stem cells (MSCs) are known to migrate to TME and interact with cancer cells via secretion of exosome- containing biomolecules, microRNA. Understanding of interaction between MSCs and cancer cells via exosomal miRNAs is important in determining the therapeutic role of MSC in treating breast cancer cells and relapse. In this study, exosomes were harvested from a medium of indirect co-culture of MCF7-luminal and MDA-MB-231-basal breast cancer cells (BCCs) subtypes with adipose MSCs. The interaction resulted in different exosomal miRNAs profiles that modulate essential signaling pathways and cell cycle arrest into dormancy via inhibition of metastasis and epithelial-to-mesenchymal transition (EMT). Overall, breast cancer cells displayed a change towards a more dormant-epithelial phenotype associated with lower rates of metastasis and higher chemoresistance. The study highlights the crucial roles of adipose MSCs in inducing dormancy and identifying miRNAs-dormancy related markers that could be used to identify the metastatic pattern, predict relapses in cancer patients and to be potential candidate targets for new targeted therapy.

[PMID: 32669977 PMCID: PMC7350616 DOI: 10.1186/s12935-020-01396-4] [Citation(s) in RCA: 23] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2020] [Accepted: 07/01/2020] [Indexed: 02/08/2023] Open
Abstract
Background Researches validate that circular RNAs (circRNAs) are dysregulated in a variety of malignancies and play an important role in regulating the malignant phenotype of tumor cells. Nevertheless, the role of circ_0000527 in retinoblastoma (RB) and its regulatory mechanisms remain largely unknown. Methods Real-time PCR (RT-PCR) was used to detect circ_0000527 and miR-646 expression in RB tissues and cells. The LRP6 expression in RB cells was detected by Western blot. The relationship between circ_0000527 expression and the clinicopathological parameters of RB patients was analyzed. Cell proliferation, apoptosis and metastasis were monitored by cell counting kit-8 (CCK-8), flow cytometry, and Transwell assay. The dual-luciferase reporter gene assay and RIP assay were employed to verify the targeting relationship between circ_0000527 and miR-646, miR-646 and LRP6. Results Circ_0000527 was highly expressed in both RB and RB cell lines, whose high expression level and degree of differentiation were significantly correlated with the increase in cTNM staging level. Overexpression of circ_0000527 contributed to RB cell proliferation, migration, invasion and suppressed cell apoptosis, while knocking down circ_0000527 inhibited the above malignant biological behavior. The underlying mechanism suggested that functioning as a endogenous competitive RNA, circ_0000527 directly targeted miR-646 and positively regulated LRP6 expression. Conclusion Circ_0000527 enhances the proliferation and metastasis of RB cells by modulating the miR-646/LRP6 axis.

Abstract
Purpose Osteosarcoma (OS) is an invasive bone tumor that primarily affects children and adolescents. MicroRNA-629 (miR-629) acts as an oncogene involved in the development of various cancers. This study aims to reveal the clinical significance and biological function of miR-629 in OS. Patients and Methods The levels of miR-629 expression in tissues and cells were detected through quantitative real-time polymerase chain reaction (qRT-PCR). Chi-square test was used to evaluate the relationship between miR-621 expression and clinical parameters in patients with OS. Survival analysis was performed by the Kaplan-Meier method. Cox regression analysis of the effect of miR-629 expression on the prognosis of OS patients. CCK-8 and Transwell experiments were used to demonstrate the effect of miR-629 on OS cell function. Results Compared with the controls, miR-629 levels were significantly elevated in patients with OS (P < 0.001), Furthermore, miR-629 upregulation showed significantly associated with clinical stage (P = 0.011), distant metastasis (P = 0.003) and poor survival (log rank test, P = 0.013) in OS patients. miR-629 might be a potential prognostic biomarker for OS (HR = 2.890, 95% CI = 1.126-7.416, P = 0.027). Cell function experiments proved that the high expression of miR-629 promoted cell proliferation, migration, and invasion of OS. Conclusion All experimental results demonstrated that miR-629 as an oncogene promotes the tumor cell growth, migration and invasion of OS, and miR-629 may act as a novel prognostic biomarker and therapeutic target for patients with this malignant tumor.

Abstract
Some new treatment methods have been explored to delay the recurrence of colorectal cancer (CRC). Early diagnosis plays an important role in the improvement of curative effect. The conventional methods used to diagnose and monitor CRC are fecal occult blood test (FOBT) and colonoscopy. However, FOBT has an unsatisfactory sensitivity, while colonoscopy is expensive and invasive. As new biomarkers, microRNAs, which can be detected in CRC tissues, cells, and body fluid as tumor suppressors or oncogenes, can be used in early diagnosis, the monitoring of metastasis and treatment, as well prognostic evaluation of CRC. This article reviews the diagnostic and prognostic value of microRNAs in CRC.
