Front Oncol 2021; 11:671853. [PMID: 34221989 PMCID: PMC8250440 DOI: 10.3389/fonc.2021.671853] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2021] [Accepted: 04/26/2021] [Indexed: 12/26/2022] Open
Abstract
Background LncRNA-FGD5-AS1, as an oncogene, participates in the development and progress of various cancers. However, the exact role and the molecular mechanisms by which FGD5-AS1 regulates radiosensitivity in breast cancer (BC) remains largely unknown. Methods We used X-Ray weekly-dose-increase method to establish radiation-resistance cell lines. Bioinformatics tools analyze the expression of FGD5-AS1 in breast cancer tissue and evaluated the relationship between FGD5-AS1 and clinic-pathological features. CCK-8 and colony formation were used to analyze cell proliferation. Western blotting and qPCR were applied to detect protein and gene expression, respectively. RNA interference was used to knock down the endogenous gene expression. Luciferase reporter system and immunoprecipitates were applied to verify the target of FGD5-AS1. Result FGD5-AS1 was overexpressed in BC tissues and radiation-resistance cell lines. Higher levels of FGD5-AS1 predicted poorer clinical characteristics and prognosis. Loss-of-function FGD5-AS1 sensitized BC cells to X-ray, meanwhile, the cell gained radiation-resistance when exogenous FGD5-AS1 was expressed. FGD5-AS1 depletion arrested cells at G0/G1 and triggers cell apoptosis. The starBase database (ENCORI), predicted binding site of miR-497-5p in FGD5-AS1 sequence, and luciferase reporter system and immunoprecipitates verified miR-497-5p was the target of FGD5-AS1. Furthermore, MACC1 was predicted and verified as the target of miR-497-5p. Loss-of-function FGD5-AS1 sensitized ionizing radiation was rescued by the up-regulation of MACC1 and the inhibition of miR-497. Conclusion FGD5-AS1 displays an oncogene profile in CRC; patients with high expression of FGD5-AS1 should benefit less from radiotherapy and need a more frequent follow-up. Besides, FGD5-AS1 may be a potential therapeutic target for CRC.

Abstract
Objective To detect the expression of microRNA-338-3p (miR-338-3p) and MET transcriptional regulator MACC1 (MACC1) gene in different ovarian tissues, to analyze their relationships, their correlations to the clinicopathologic characteristics of epithelial ovarian cancer and their significant to the progression of ovarian cancer. Methods The expression of miR-338-3p and MACC1 gene in 20 specimens of normal ovarian tissues, 20 specimens of benign epithelial ovarian tumor and 65 specimens of epithelial ovarian cancer was detected by real-time PCR method. Their interrelationships and their correlations to the clinicopathologic characteristics of epithelial ovarian cancer were analyzed. Risk factors of recurrence and death were discussed by binary Logistic regression analysis. The relations between miR-338-3p and MACC1 expression and the survival of ovarian cancer were measured by Kaplan-Meier analysis. Results The expressions of miR-338-3p and MACC1 gene in epithelial ovarian cancer tissues were (0.331±0.038) and (0.774±0.025), significant differences were noted between epithelial ovarian cancer and normal ovarian tissues, benign ovarian tumors (F=77.916, P=1.205E-18; F=77.945, P=1.187E-18). In different ovarian tissues, miR-338-3p expression was negatively correlated to MACC1 expression (r = -0.968, P<0.0001). In epithelial ovarian cancer, lower expression of miR-338-3p and higher expression of MACC1 were associated with more advanced FIGO stage, higher histological grade and developed lymph node metastasis. Down-regulation of miR-338-3p was related with the recurrence (P=0. 005, OR=12.862, 95%CI: 2.120~78.026) and death (P=0. 007, OR=12.837, 95%CI: 2.205~81.389) of ovarian cancer patients, which was showed by binary Logistic regression analysis. Compared to other patients, the overall survival rate and progression free survival rate of patients with lower miR-338-3p and higher MACC1 expression were obviously poorer (χ2=16.955, P=7.219E-5; χ2=18.929, P=2.828E-5). Conclusions Down-regulation of miR-338-3p and up-regulation of MACC1 gene were closely related with the poor prognosis of epithelial ovarian cancer patients, which could served as bio-markers of the progression and recurrence of ovarian cancer.

Abstract
Colorectal cancer (CRC) is the fourth most frequent type of malignancy in the world. Metastasis accounts for >90% mortalities in patients with CRC. The metastasis-associated in colon cancer 1 (MACC1) gene has been identified as a novel biomarker for the prediction of metastasis and disease prognosis, particularly for patients with early-stage disease. Previous clinical studies demonstrated that MACC1 expression and polymorphisms in CRC tissues were indicators of metastasis, and that circulating transcripts in plasma were also significantly associated with the survival of patients. The present review describes the use of MACC1 beyond its utility in the clinic. By elucidating the upstream and downstream signal pathways of MACC1, the well-known mechanisms of MACC1-mediated cell proliferation, invasion, migration and epithelial-mesenchymal transition (EMT) are summarized, as well as the potential signaling pathways. Furthermore, the underlying mechanisms by which the overexpression of MACC1 causes cisplatin resistance are emphasized.

Abstract
MACC1 (Metastasis Associated in Colon Cancer 1) is a key driver and prognostic biomarker for cancer progression and metastasis in a large variety of solid tumor types, particularly colorectal cancer (CRC). However, no MACC1 inhibitors have been identified yet. Therefore, we aimed to target MACC1 expression using a luciferase reporter-based high-throughput screening with the ChemBioNet library of more than 30,000 compounds. The small molecules lovastatin and rottlerin emerged as the most potent MACC1 transcriptional inhibitors. They remarkably inhibited MACC1 promoter activity and expression, resulting in reduced cell motility. Lovastatin impaired the binding of the transcription factors c-Jun and Sp1 to the MACC1 promoter, thereby inhibiting MACC1 transcription. Most importantly, in CRC-xenografted mice, lovastatin and rottlerin restricted MACC1 expression and liver metastasis. This is-to the best of our knowledge-the first identification of inhibitors restricting cancer progression and metastasis via the novel target MACC1. This drug repositioning might be of therapeutic value for CRC patients.

Abstract
Metastasis-associated in colon cancer-1 (MACC1), has recently been identified as a key regulator in the progression of many cancers. However, its role in endometrial carcinoma (EC) remains unknown. MACC1 expression was determined in EC and normal endometrial tissues by immunohistochemistry. EC cell phenotypes and related molecules were examined after MACC1 downregulation by Small interfering RNA (siRNA) or microRNA (miRNA) transfection. We found that MACC1 was highly expressed in EC tissues than normal samples, and was significantly different in FIGO staging (I and II vs. III and IV), the depth of myometrial infiltration (<1/2 vs. ≥1/2), lymph nodes metastasis (negative vs. positive), besides, MACC1 overexpression was correlated with lower cumulative and relapse-free survival rate. MACC1 downregulation by siRNA transfection significantly induced G1 phrase arrest, suppressed EC cell proliferation, migration, and invasion. In addition, MACC1 downregulation also reduced expression of Cyclin D1 and Cyclin-dependent Kinase 2 (CDK2), N-cadherin (N-Ca), α-SMA, matrix metalloproteinase 2 (MMP2), and MMP9, but increased expression of E-cadherin (E-Ca). Bioinformatic predictions and dual-luciferase reporter assays indicate that MACC1 is a possible target of miR-23b. MiR-23b overexpression reduced MACC1 expression in vitro and induced G1 phrase arrest, suppressed cell proliferation, migration, and invasion. MiR-23b transfection also reduced Cyclin D1 and CDK2, N-Ca, α-SMA, MMP2, MMP9 expression, but increased E-Ca expression. Furthermore, the nude mouse xenograft assay showed that miR-23b overexpression suppressed tumour growth through downregulating MACC1 expression. Taken together, our results demonstrate for the first time that MACC1 may be a new and important diagnosis and therapeutic target of endometrial carcinoma.

Abstract
The metastasis-associated in colon cancer-1 (MACC1) gene was identified in 2009. Expression of MACC1 was found to be significantly upregulated in primary and metastatic colon carcinomas compared to normal tissues or adenomas. The induction of MACC1 occurs at the crucial step of transition from a benign to a malignant phenotype. The aim of this review was to summarise current results of non-clinical and clinical studies on the role of MACC1 in the carcinogenesis and progression of cancer, as well its potential therapeutic and prognostic significance. The gene encoding the HGF receptor MET is a transcriptional target of MACC1. In addition to promoting the proliferation, invasion, and migration of colon cancer cells in cell culture and tumour growth and metastasis in mouse models, MACC1 also contributes to carcinogenesis and progression of colorectal cancer through the β-catenin signalling pathway and mesenchymal-epithelial transition. MACC1 knockdown with si/sh RNA was investigated in cell lines of different types of cancer. MACC1 is a promising therapeutic target for antitumour and antimetastatic intervention strategies for cancers. Here, it is presented as a potential independent prognostic indicator of reduced overall survival as well as of the occurrence of distant metastasis in patients with different types of cancer.

Abstract
Background Human brain glioma is the most common endocranial tumor; its mortality and morbidity are very high. The objective of this study was to determine whether miR-338-3p can regulate malignant biological behaviors of glioma cells by targeted silencing of MACC1. Material/Methods The expression of miR-338-3p was detected by quantitative real-time PCR in brain glioma tissues and cell lines. Bioinformatics software was used to predict some potential target genes of miR-338-3p. Luciferase activities assay was used to verify the combination between target genes and miR-338-3p. And MACC1 protein expression was detected by Western blot. The apoptosis and proliferation ability were analyzed by MTT and flow cytometry assay. Results Compared with normal brain tissues and cells, miR-338-3p in glioma tissues and cell lines was confirmed to be expressed at low levels, and down-regulation of miR-338-3p tended to be correlated with worse histological grade. Up-regulation of miR-338-3p promoted apoptosis and sharply inhibited cell proliferation ability of U251 and U87 cells. The luciferase activities assay, biotin-avidin pull-down assay, and western blot analysis verified that MACC1 was a specific target gene of miR-338-3p. Subsequent experiments found that up-regulation of MACC1 significantly inhibited the apoptosis and increased the cell proliferation ability of U251 and U87 cells. The regulation effects of miR-338-3p on malignant biological behaviors of glioma cells can be partly reversed by up-regulation of MACC1. Conclusions Down-regulation of miR-338-3p was an independent prognostic biomarker associated with poor prognosis in glioma patients; miR-338-3p acted as a tumor-suppressing gene whose silencing can inhibit malignant biological behaviors of glioma cells. MACC1 was a specific target gene of miR-338-3p, which regulates malignant biological behaviors of glioma cells partly through directly silencing MACC1 expression.

Abstract
The consequence of a loss of balance between G-protein activation and deactivation in cancers has been interrogated by studying infrequently occurring mutants of trimeric G-protein α-subunits and GPCRs. Prior studies on members of a newly identified family of non-receptor guanine nucleotide exchange factors (GEFs), GIV/Girdin, Daple, NUCB1 and NUCB2 have revealed that GPCR-independent hyperactivation of trimeric G proteins can fuel metastatic progression in a variety of cancers. Here we report that elevated expression of each GEF in circulating tumor cells (CTCs) isolated from the peripheral circulation of patients with metastatic colorectal cancer is associated with a shorter progression-free survival (PFS). The GEFs were stronger prognostic markers than two other markers of cancer progression, S100A4 and MACC1, and clustering of all GEFs together improved the prognostic accuracy of the individual family members; PFS was significantly lower in the high-GEFs versus the low-GEFs groups [H.R = 5, 20 (95% CI; 2,15–12,57)]. Because nucleotide exchange is the rate-limiting step in cyclical activation of G-proteins, the poor prognosis conferred by these GEFs in CTCs implies that hyperactivation of G-protein signaling by these GEFs is an important event during metastatic progression, and may be more frequently encountered than mutations in G-proteins and/or GPCRs.

Abstract
Metastasis-associated in colon cancer-1 (MACC1), a newly identified oncogene, promotes tumor proliferation and invasion via the MET pathway. The purpose of this study is to determine the clinical significance of MACC1 and MET expression in the long-term survival and recurrence in a large cohort of gastric carcinoma patients following curative resection. We evaluated the prognostic value of MACC1 and MET expression using immunohistochemistry in 331 gastric adenocarcinoma patients. MACC1-positive patients had lower overall survival (OS) or event-free survival (EFS) rates than MACC1-negative patients (P=0.039 and P=0.044, respectively), while MET positivity itself was not associated with either OS or EFS. Multivariate analysis identified the expression level of MACC1 protein as an independent negative prognostic factor for OS or EFS (P=0.021 and P=0.016, respectively). This study suggests that MACC1 is an independent prognostic factor in gastric adenocarcinoma and that the prognostic impact of MACC1 may be associated with MACC1 partners other than MET.

Abstract
Metastasis associated in colon cancer-1 (MACC1) is a newly identified oncogene, and increasing evidence has suggested that its overexpression is associated with the development and progression in many tumors. Here, we perform a meta-analysis to assess the relationship between MACC1 overexpression and survival in solid tumors. Eligible studies were searched in Embase, PubMed, and Web of Science databases up to May 2014. Pooled hazard ratios (HRs) with 95% confidence intervals (CIs) were calculated to estimate the impact of MACC1 overexpression on survival using a random-effect model. A total of 20 eligible studies dealing with various tumors were included in the analysis: 17 were dealing with overall survival (OS), 7 were with relapse-free survival (RFS), and 3 were with disease-free survival (DFS). Combined results suggested a strong link between the high MACC1 expression and the poor overall survival (HR 2.11, 95% CI 1.59-2.80, P < 0.001). For relapse-free survival, overexpressed MACC1 was also a significant predictor, with a combined HR of 2.22 (95% CI 1.80-2.74, P < 0.001). Data from the three studies were combined to show that MACC1 overexpression had also an unfavorable impact on disease-free survival (HR 2.94, 95% CI 1.60-5.38, P < 0.001). Publication bias was not significant. The present meta-analysis showed that overexpression of MACC1 was significantly associated with poorer survival in solid tumors.
