Abstract
In recent years, microRNAs (miRNAs or miRs) have been increasingly studied for their role in cancer and have shown potential as cancer biomarkers. miR‑143‑3p and miR‑143‑5p are the mature miRNAs derived from pre‑miRNA‑143. At present, there are numerous studies on the function of miR‑143‑3p in cancer progression, but there are no systematic reviews describing the function of miR‑143‑3p in cancer. It is widely considered that miR‑143‑3p is downregulated in most malignant tumors and that upstream regulators can act on this gene, which in turn regulates the corresponding target to act on the tumor. In addition, miRNA‑143‑3p can regulate target genes to affect the biological process of tumors through various signaling pathways, such as the PI3K/Akt, Wnt/β‑catenin, AKT/STAT3 and Ras‑Raf‑MEK‑ERK pathways. The present review comprehensively described the biogenesis of miR‑143‑3p, the biological functions of miR‑143‑3p and the related roles and mechanisms in different cancer types. The potential of miR‑143‑3p as a biomarker for cancer was also highlighted and valuable future research directions were discussed.

Microrna 2024; 13:56-62. [PMID: 38231064 PMCID: PMC11275315 DOI: 10.2174/0122115366266024240101075745] [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: 08/22/2023] [Revised: 11/10/2023] [Accepted: 11/16/2023] [Indexed: 01/18/2024]
Abstract
BACKGROUND Colorectal cancer (CRC) is the third most common cancer in the world. Noncoding RNAs or microRNAs (miRNAs; miRs) biomarkers can play a role in cancer carcinogenesis and progression. Specific KRAS and EGFR mutation are associated with CRC development playing a role in controlling the cellular process as epigenetic events. Circulating serum miRs can serve for early diagnosis, monitoring, and prognosis of CRC as biomarkers but it is still unclear, clinically. OBJECTIVE To determine potential biomarkers of circulating serum miR-133b and miR-206 in CRC patients Methods: Bioinformatic prediction of microRNA was screened followed by TargetScanHuman7.2, miRTar2GO, miRDB, MiRanda, and DIANA-microT-CDS. Forty-four CRC serum (19 locally advanced, 23 distant advanced CRC) and 12 normal serum samples were subsequently extracted for RNA isolation, cDNA synthesis, and miR validation. The candidate circulating serum miR-133b and miR-206 were validated resulting in a relative expression via quantitative RT-PCR. Relative expression was normalized to the spike-internal control and compared to normal samples as 1 using the -2ΔΔCt method in principle. RESULTS Our results represented 9 miRs of miR-206, miR-155-5p, miR-143-3p, miR-193a-3p, miR-30a- 5p, miR-30d-5p, miR-30e-5p, miR-543, miR-877-5p relate to KRAS-specific miRs, whereas, 9 miRs of miR-133b, miR-302a-3p, miR-302b-3p, miR-302d-3p, miR-302e, miR-520a-3p, miR-520b, miR-520c- 3p and miR-7-5p relevance to EGFR-specific miRs by using the bioinformatic prediction tools. Our results showed a decreased expression level of circulating serum miR-133b as well as miR-206 associating with CRC patients (local and advanced metastasis) when compared to normal (P < 0.05), significantly. CONCLUSION The circulating serum miR-133b and miR-206 can serve as significant biomarkers for monitoring the clinical outcome of progression with metastatic CRC patients. Increased drug-responsive CRC patients associated with crucial molecular intervention should be further explored, clinically.

Int Immunopharmacol 2023; 119:110137.

Abstract
Extracellular vesicles (EVs) exhibit pivotal functions in cancer via intercellular communication through shuttling microRNA (miRNA) and protein. Therefore, we aim to elucidate the function of EVs containing miR-143-3p derived from M2 macrophages in colorectal cancer (CRC). EVs derived from M2 macrophages were isolated and characterized. Expression changes in miR-143-3p were calculated in the EVs. The effects of M2 macrophage-derived EV carrying miR-143-3p on cell biological processes and in vivo tumorigenic ability concerning ZC3H12A were examined. EVs derived from M2 macrophages could stimulate the aggressive tumor biology of CRC cells. Meanwhile, in vivo results showed that M2 macrophage-derived EVs facilitated tumor growth and epithelial-mesenchymal transition. M2 macrophage-secreted EVs could transfer miR-143-3p to CRC cells, in which miR-143-3p bound to the 3'UTR of ZC3H12A and inhibited its expression, leading to elevation of the expression of transcription factor C/EBPβ. Overall, M2 macrophage-derived EV miR-143-3p inhibits ZC3H12A gene and increases C/EBPβ expression to facilitate the development of CRC, which provides novel targets for the molecular treatment of CRC.

Abstract
BACKGROUND No effective early diagnostic biomarkers are available for colorectal cancer (CRC). Therefore, we sought to identify new biomarkers that could identify CRC from progression as a pre-cancerous lesion to its invasive form. Recent studies have shown that microRNAs (miRs) are associated with the onset of cancer invasion and progression. AIMS We hypothesized that the identification of miRs associated with CRC might be useful to detect this disease at early stages. METHODS We conducted an integrated analysis of 79 isolated colorectal tumor glands, including adenomas, intramucosal cancers, and invasive CRCs that showed a microsatellite stable phenotype using GeneChip miRNA 4.0 microarray assays. The colorectal tumors we examined were divided into 2 cohorts (42 in the first cohort and 37 in the second cohort). RESULTS First, cluster analysis was performed to stratify expression patterns of multiple miRs that were pooled according to the following criteria: fold change in expression (< -2.0 or > 2.0), p < 0.05, and mature miRs. As a result, the expression patterns of pooled miRs were subdivided into 3 subgroups that were correlated with tumor grade. Each subgroup was characterized by specific miRs. In addition, we found that specific miRs, including miR-140-3p and miR-378i, were closely associated with cancer invasion. Finally, we analyzed paired dysregulated miRs between adenomatous and cancerous components present within the same tumor. DISCUSSION We showed that several miRs were dysregulated during progression from adenoma to intramucosal cancer. Specific miRs may have key roles in progression from intramucosal tumor to invasive CRC.

Abstract
OBJECTIVE Colorectal cancer is one of the most common gastrointestinal tumors. The role of Wnt7b as a ligand of the Wnt signaling pathway in colorectal cancer remains to be studied. Through bioinformatics online analysis, we found that Wnt7b is abnormally highly expressed in a variety of gastrointestinal tumors. This study mainly explored the effects of Wnt7b regulating the Wnt/β-catenin signaling pathway on the proliferation, migration, and invasion of SW480 cells in colorectal cancer. METHODS AND RESULTS Applying the TCGA data set, Wnt7b was found to be highly expressed in most gastrointestinal tumor samples. Real-time quantitative PCR(q-PCR), Western blotting(WB) results showed that Wnt7b was significantly higher expressed in colorectal cancer cell lines compared with normal intestinal epithelial cells. SW480 cells transfected with the sh-Wnt7b showed successful knockdown of Wnt7b. MTT colorimetry showed the proliferation ability of sh-Wnt7b group decreased significantly compared with the non-transfected group. The results of double staining flow cytometry showed that the sh-Wnt7b group had more apoptosis. Cell scratch test showed that the cell migration rate of sh-wnt7b group considerably reduced. The Transwell invasion experiment demonstrated that the number of cell invasions in the sh-Wnt7b group decreased significantly. After SW480 cells was transfected with sh-Wnt7b, the protein levels of β-catenin, CCND1, and CD44 in this group of cells were detected to be reduced by WB, and the same results were obtained by q-PCR detection of mRNA. CONCLUSION Wnt7b is highly expressed in colorectal cancer cells, which may affect the proliferation, migration, and invasion of colorectal cancer cells by activating the Wnt/β-catenin signaling pathway.

Abstract
The gastrointestinal (GI) tract in mammals is comprised of dozens of cell types with varied functions, structures, and histological locations that respond in a myriad of ways to epigenetic and genetic factors, environmental cues, diet, and microbiota. The homeostatic functioning of these cells contained within this complex organ system has been shown to be highly regulated by the effect of microRNAs (miRNA). Multiple efforts have uncovered that these miRNAs are often tightly influential in either the suppression or overexpression of inflammatory, apoptotic, and differentiation-related genes and proteins in a variety of cell types in colorectal cancer (CRC). The early detection of CRC and other GI cancers can be difficult, attributable to the invasive nature of prophylactic colonoscopies. Additionally, the levels of miRNAs associated with CRC in biofluids can be contradictory and, therefore, must be considered in the context of other inhibiting competitive endogenous RNAs (ceRNA) such as lncRNAs and circRNAs. There is now a high demand for disease treatments and noninvasive screenings such as testing for bloodborne or fecal miRNAs and their inhibitors/targets. The breadth of this review encompasses current literature on well-established CRC-related miRNAs and the possibilities for their use as biomarkers in the diagnoses of this potentially fatal GI cancer.

Abstract
BACKGROUND Circular RNAs (circRNAs) play crucial roles in multiple cancers, including colorectal cancer (CRC). Here, we explored the role of circRNA ArfGAP with coiled-coil, ankyrin repeat and PH domains 2 (circ-ACAP2) in the progression and radioresistance of CRC. METHODS Quantitative real-time polymerase chain reaction (qPCR) and Western blot assay were used to detect RNA and protein expression, respectively. The proliferation, apoptosis, migration, invasion and radioresistance of CRC cells were determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, flow cytometry, transwell migration assay, transwell invasion assay and colony formation assay. The target interaction between microRNA-143-3p (miR-143-3p) and circ-ACAP2 or frizzled class receptor 4 (FZD4) was verified by dual-luciferase reporter assay. Murine xenograft model was established to explore the role of circ-ACAP2 in vivo. RESULTS The expression of circ-ACAP2 was prominently enhanced in CRC tissues and cell lines. Circ-ACAP2 facilitated the proliferation, migration, invasion and radioresistance whereas inhibited the apoptosis of CRC cells. MiR-143-3p was a direct target of circ-ACAP2 in CRC cells. Circ-ACAP2 promoted the progression and radioresistance of CRC partly by sponging miR-143-3p. MiR-143-3p interacted with the 3' untranslated region (3'UTR) of FZD4 in CRC cells, and FZD4 overexpression partly reversed miR-143-3p-mediated effects in CRC cells. Wnt/β-catenin signalling was modulated by circ-ACAP2/miR-143-3p/FZD4 axis in CRC cells. CONCLUSION Circ-ACAP2 contributed to the development and radioresistance of CRC partly through targeting miR-143-3p/FZD4 axis, which provided novel potential diagnostic and therapeutic targets for CRC.

Abstract
BACKGROUND Gastric cancer is a prevalent malignant around the world. Aberrantly expression of microRNAs (miRNAs) contributes to the progression of tumors. The aim of this study was to investigate the expression and role of miR-892a in gastric cancer. METHODS A total of 119 gastric cancer patients were enrolled in this study. And the expression of miR-892a in gastric cancer tissues and cells was measured using RT-qPCR analysis. Kaplan-Meier plotter and multivariate Cox regression analysis were used to explore the prognostic value of miR-892a in gastric cancer. The biological function of miR-892a in gastric cancer cells was evaluated using CCK-8 assays and Transwell assays. RESULTS The expression of miR-892a was high-expressed in gastric cancer tissues and cells. The miR-892a expression was associated with tumor size, differentiation, lymph node metastasis, and TNM stages. Gastric cancer patients with high miR-892a expression showed a short overall survival rate. Overexpression of miR-892a promoted cell proliferation, migration, and invasion of gastric cancer cells. CONCLUSION miR-892a was upregulated and predictor of poor prognosis in gastric cancer patients. The miR-892a in gastric cancer cells significantly promoted cell proliferative, migratory, and invasive properties. Furthermore, miR-892a may be served as a prognostic marker as well as a therapeutic target for gastric cancer.

Abstract
The aberrant expression of microRNAs in known to play a crucial role in carcinogenesis. Here, we evaluated the miRNA expression profile of sigmoid colon cancer (SCC) compared to adjacent-to-tumor (ADJ) and sigmoid colon healthy (SCH) tissues obtained from colon biopsy extracted from Brazilian patients. Comparisons were performed between each group separately, considering as significant p-values < 0.05 and |Log2(Fold-Change)| > 2. We found 20 differentially expressed miRNAs (DEmiRNAs) in all comparisons, two of which were shared between SCC vs. ADJ and SCC vs. SCH. We used miRTarBase, and miRTargetLink to identify target-genes of the differentially expressed miRNAs, and DAVID and REACTOME databases for gene enrichment analysis. We also used TCGA and GTEx databases to build miRNA-gene regulatory networks and check for the reproducibility in our results. As findings, in addition to previously known miRNAs associated with colorectal cancer, we identified three potential novel biomarkers. We showed that the three types of colon tissue could be clearly distinguished using a panel composed by the 20 DEmiRNAs. Additionally, we found enriched pathways related to the carcinogenic process in which miRNA could be involved, indicating that adjacent-to-tumor tissues may be already altered and cannot be considered as healthy tissues. Overall, we expect that these findings may help in the search for biomarkers to prevent cancer progression or, at least, allow its early detection, however, more studies are needed to confirm our results.

Circular RNA circ_0000043 promotes endometrial carcinoma progression by regulating miR-1271-5p/CTNND1 axis. Arch Gynecol Obstet 2020; 303:1075-1087. [PMID: 33128584 DOI: 10.1007/s00404-020-05849-z] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2020] [Accepted: 10/16/2020] [Indexed: 10/23/2022]
Abstract
BACKGROUND Circular RNAs (circRNAs) are involved in a variety of biological processes, including tumorigenesis. However, the exact role and molecular mechanisms of circ_0000043 in endometrial carcinoma (EC) remain largely unknown. METHODS Quantitative real-time polymerase chain reaction (qRT-PCR) was carried out to determine the expression levels of circ_0000043, microRNA-1271-5p (miR-1271-5p) and catenin delta 1 (CTNND1). 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and flow cytometry were used to measure cell proliferation, cell apoptosis and cell cycle distribution, respectively. Cell migration and invasion were assessed by transwell assay. Western blot assay was performed to examine the protein expression of matrix metalloproteinase 2 (MMP2), MMP9 and CTNND1. The interaction between miR-1271-5p and circ_0000043 or CTNND1 was predicted by starBase and confirmed by dual-luciferase reporter assay. The mice xenograft model was established to investigate the role of circ_0000043 in vivo. RESULTS Circ_0000043 and CTNND1 were highly expressed and miR-1271-5p was lowly expressed in EC tissues and cells. Knockdown of circ_0000043 inhibited the progression of EC by inhibiting cell proliferation, migration, invasion and tumor growth (in vivo) and promoting apoptosis. MiR-1271-5p was a direct target of circ_0000043 and its inhibition reversed the inhibitory effect of circ_0000043 knockdown on the progression of EC cells. In addition, CTNND1 was a downstream target of miR-1271-5p, and miR-1271-5p overexpression inhibited EC cell proliferation, migration and invasion and induced apoptosis by targeting CTNND1. Moreover, circ_0000043 positively regulated CTNND1 expression by sponging miR-1271-5p. CONCLUSION Circ_0000043 knockdown inhibited the progression of EC by regulating miR-1271-5p/CTNND1 axis, which might provide a promising circRNA-targeted therapy for EC.

Abstract
MicroRNAs (miRNAs) are potential biomarkers of neoplastic lesions, but additional information on dysregulated miRNA expression during progression of the adenoma-adenocarcinoma sequence may be helpful to identify the role of miRNAs in this sequence. We examined the expression levels of 13 miRNAs (hsa-miRNA-19a-3p, hsa-miRNA-21-5p, hsa-miRNA-27a-3p, hsa-miRNA-27b-3p, hsa-miRNA-31-5p, hsa-miRNA-34b-3p, hsa-miRNA-125b-5p, hsa-miRNA-143-3p, miRNA-191-5p, hsa-miRNA-193b-3p, hsa-miRNA-195-5p, hsa-miRNA-206 and hsa-let-7a-5p) that are closely associated with colorectal carcinogenesis in 40 conventional adenomas (tubular and tubulovillous adenomas), 20 intramucosal carcinomas (IMCs) and 60 invasive colorectal cancers (iCRCs) using reverse-transcription polymerase chain reaction. These 120 tumors were divided into two cohorts, that is, cohort 1 (60 cases) and cohort 2 (for validation; 60 cases). We analyzed the expression levels of these miRNAs in the first step (adenoma→IMC) and second step IMC→iCRC) of the adenoma-carcinoma sequence in both cohorts. Although no significant differences in the expression of any of the 13 miRNAs were found between adenomas and IMCs consistently in both cohorts, the expression levels of hsa-miRNA-125b-5p, hsa-miRNA-143-3p, and hsa-miRNA-206 were significantly upregulated in iCRC in both cohorts compared with those in IMC. The current results suggest that certain miRNAs, including hsa-miRNA-125b-5p, hsa-miRNA-143-3p and hsa-miRNA-206, are candidate markers that play critical roles in the progression of IMC to iCRC.

[PMID: 32945436 PMCID: PMC7453500 DOI: 10.3892/mmr.2020.11427] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2019] [Accepted: 07/06/2020] [Indexed: 12/30/2022] Open
Abstract
Long non-coding RNAs (lncRNAs) are widely studied in cancer pathogenesis. Accumulating evidence has demonstrated that lncRNAs are involved in the cellular progression of colorectal cancer (CRC). However, the regulatory mechanism of lncRNA TMPO-antisense (AS)1 in CRC has not been fully elucidated. The present study aimed to elucidate the role and regulatory mechanisms of lncRNA TMPO-AS1 in CRC. In the present study, the expression levels of TMPO-AS1 and microRNA-143-3p (miR-143-3p) were detected using reverse transcription-quantitative PCR assay. The relative protein expression levels were measured via western blot analysis. MTT and Transwell assays were used to determine cell proliferation, migration and invasion, while a luciferase reporter assay was performed to assess the relationship between TMPO-AS1 and miR-143-3p. In addition, a tumor animal model was used to investigate the effect of TMPO-AS1 on tumor growth in CRC in vivo. TMPO-AS1 expression was increased and miR-143-3p expression was decreased in CRC cells. TMPO-AS1 knockdown and miR-143-3p overexpression significantly inhibited cell proliferation, migration and invasion of CRC cells. Luciferase reporter assay results demonstrated that miR-143-3p was a direct target of TMPO-AS1. Inhibition of miR-143-3p could alleviate the suppressive effects of TMPO-AS1 deletion on cell proliferation, migration and invasion of CRC cells. Furthermore, TMPO-AS1 deletion could inhibit tumor growth in CRC in vivo. It was concluded that TMPO-AS1 regulated cell proliferation, migration and invasion of CRC cells by targeting miR-143-3p. These findings provided a new regulatory network and therapeutic target for the treatment of CRC.

Abstract
Colorectal cancer (CRC) is a common malignancy with high mortality. However, the roles of miR-425-5p and its underlying mechanism in CRC remain unknown. Here, RT-qPCR confirmed that miR-425-5p expression was increased by miR-425-5p mimic in SW480 cells and decreased by miR-425-5p inhibitor in LOVO cells. CCK-8, flow cytometry, wound healing and transwell assays revealed that the increased miR-425-5p promoted cell viability, cell cycle entry, migration and invasion in CRC. Besides, miR-425-5p overexpression induced epithelial-mesenchymal transition (EMT) with upregulation of Fibronectin, N-cadherin, Vimentin, and downregulation of E-cadherin. Moreover, miR-425-5p overexpression induced c-myc, Cyclin D1 and MMP7 levels, and promoted β-catenin translocation to the nucleus. Knockdown of miR-425-5p exerted opposite effects. Luciferase reporter assay indicated that miR-425-5p directly targeted CTNND1. Overexpression of miR-425-5p repressed CTNND1 expression at mRNA and protein levels. Silencing of CTNND1 had the inhibitory effect of miR-425-5p inhibitor on cell proliferation, migration, invasion, EMT, and the activation of β-catenin signaling pathway. Furthermore, miR-425-5p promoted tumor growth and metastasis in vivo. In conclusion, miR-425-5p may promote tumorigenesis and metastasis through activating CTNND1-mediated β-catenin pathway, which may provide therapeutic targets for human CRC.

Abstract
MicroRNAs (miRs) have shown tremendous potential to act as therapeutic targets for cancer treatment. In this context, the present study was designed to investigate the potential of miR-143 in the treatment of breast cancer. Results showed that miR-143 to be significantly (P < 0.05) downregulated in breast cancer tissues and cell lines. The miR-143 has inhibitory effect on CAMA-1cell growth which was manifested as significant (P < 0.05) decline in loss of viability of cancer cells. The loss of cell viability was revealed to be due to the induction of apoptotic cell death as evident from acridine orange/ethidium bromide (AO/EB) and 4′,6-diamidino-2-phenylindole (DAPI) staining assays. The apoptotic cell percentage was found to be 35.7% in miR-143 mimics transfected in comparison to 6.4% in miR-NC transfected cells. The western blot analysis showed that miR-143 caused enhancement in Bax and suppression in Bcl-2 expression in CAMA-1 cells. The miR-143 also suppressed the bone metastasis of the CAMA-1 cells by suppressing the expression of Jag1 and deactivation of the Rho-signalling pathway. The transwell assays also showed considerable anti-metastatic effects of miR-143 on CAMA-1 cells. Taken together, miR-143 has growth inhibitory anti-metastatic effect on breast cancer and thus may prove beneficial in breast cancer treatment.

Abstract
Background Long non-coding RNAs (lncRNAs) have been certified to be involved in the occurrence and growth of diverse cancers, including CRC. The purpose of the research was to explore the effects of lncRNA KCNQ1 overlapping transcript 1 (KCNQ1OT1) on proliferation, migration, invasion, and apoptosis in CRC cells and its mechanism. Methods The levels of KCNQ1OT1 and miR-329-3p were examined by quantitative real-time polymerase chain reaction (qRT-PCR) in CRC tissues and cells. The mRNA and protein levels of catenin delta-1 (CTNND1) were measured by qRT-PCR and western blot analysis, respectively. The targets of KCNQ1OT1 and miR-329-3p were predicted by online software and confirmed by luciferase reporter assay. The cell proliferation, migration, invasion, and apoptosis were examined using 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT), transwell, and apoptosis assay. The expression levels of CyclinD1, Bcl-2, MMP9, Cleaved-casp-3, and E-cadherin in SW480 and LS1034 cells were gauged by western blot analysis. Xenograft tumor model was structured to prove the biological role of KCNQ1OT1 of CRC in vivo. Results The levels of KCNQ1OT1 and CTNND1 were significantly increased in CRC tissues and cells. Knockdown of KCNQ1OT1 suppressed proliferation, migration, invasion, and induced apoptosis in CRC cells. Conversely, CTNND1 overexpression reversed the impact of KCNQ1OT1 knockdown on CRC cells. Moreover, CTNND1 was verified as a direct target of miR-329-3p, and miR-329-3p could specially bind to KCNQ1OT1. Also, the down-regulation of KCNQ1OT1 triggered the CRC progress by up-regulating CTNND1 expression in CRC cells. Besides, KCNQ1OT1 knockdown inhibited CRC tumor growth through the miR-329-3p/CTNND1 axis in vivo. Conclusion Our results indicated that KCNQ1OT1 could positively regulate CTNND1 expression by sponging miR-329-3p, thereby boosting the progression of CRC. Our findings provided the underlying therapy targets for CRC.

Abstract
Regulation of microRNA (miRNA) expression has been extensively studied with respect to colorectal cancer (CRC), since CRC is one of the leading causes of cancer mortality worldwide. Transcriptional control of miRNAs creating clusters can be, to some extent, estimated from cluster position on a chromosome. Levels of miRNAs are also controlled by miRNAs "sponging" by long non-coding RNAs (ncRNAs). Both types of miRNA regulation strongly influence their function. We focused on clusters of miRNAs found to be down-regulated in CRC, containing miR-1, let-7, miR-15, miR-16, miR-99, miR-100, miR-125, miR-133, miR-143, miR-145, miR-192, miR-194, miR-195, miR-206, miR-215, miR-302, miR-367 and miR-497 and analysed their genome position, regulation and functions. Only evidence provided with the use of CRC in vivo and/or in vitro models was taken into consideration. Comprehensive research revealed that down-regulated miRNA clusters in CRC are mostly located in a gene intron and, in a majority of cases, miRNA clusters possess cluster-specific transcriptional regulation. For all selected clusters, regulation mediated by long ncRNA was experimentally demonstrated in CRC, at least in one cluster member. Oncostatic functions were predominantly linked with the reviewed miRNAs, and their high expression was usually associated with better survival. These findings implicate the potential of down-regulated clusters in CRC to become promising multi-targets for therapeutic manipulation.

Abstract
The aim of the present study was to explore the roles of microRNA-1307-3p (miR-1307-3p) in colorectal cancer (CRC). Firstly, the expression level of miR-1307-3p in CRC cells was measured using reverse transcription-quantitative PCR. Subsequently, Cell Counting Kit-8 and Transwell invasion assays were performed to evaluate the effects of miR-1307-3p on CRC cell proliferation and invasion, respectively. Bioinformatics tools and dual luciferase reporter assays were used to validate the targets of miR-1307-3p. Rescue experiments were performed to confirm tumor suppressor candidate 5 (TUSC5) as a functional target of miR-1307-3p. miR-1307-3p levels were revealed to be upregulated in CRC cells when compared with the normal human epithelial cell line. Knockdown of miR-1307-3p inhibited CRC cell growth and invasiveness. Bioinformatics analysis and dual-luciferase activity reporter assays demonstrated that miR-1307-3p binds the 3'-untranslated region of TUSC5. Finally, rescue experiments validated that miR-1307-3p was able to regulate CRC cell behaviors via regulating TUSC5 expression. Together, the current results indicate that miR-1307-3p functions as an oncogenic miRNA via targeting TUSC5 in CRC.

Abstract
Background Numerous literatures have demonstrated that circular RNAs (circRNAs) are involved in multiple types of tumors. However, the effects of circRNAs in melanoma are not very clear. In this study, we aimed to investigate the roles and mechanisms of circ-FOXM1 in melanoma. Methods Quantitative real-time polymerase chain reaction (qRT-PCR) was conducted to determine the expression of circ-FOXM1, microRNA-143-3p (miR-143-3p), and Flotillin 2 (FLOT2) mRNA. 3-(4,5-Dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) assay, flow cytometry analysis, and transwell assay were employed to test cell proliferation, apoptosis, and invasion, respectively. The glucose consumption and lactate production were examined by specific kits. Western blot assay was utilized for the detection of hexokinase2 (HK2), pyruvate kinase isozyme type M2 (PKM2), and FLOT2. Dual-luciferase reporter assay and RNA immunoprecipitation (RIP) assay were employed to verify the targeting association between miR-143-3p and circ-FOXM1 or FLOT2. A murine xenograft model was established to explore the effect of circ-FOXM1 in vivo. Results Circ-FOXM1 was elevated and miR-143-3p was reduced in melanoma tissues and cells. Circ-FOXM1 deficiency impeded cell proliferation, invasion, and glycolysis and facilitated cell apoptosis in melanoma in vitro and tumorigenesis in vivo. Circ-FOXM1 acted as a sponge of miR-143-3p and the impacts of circ-FOXM1 silencing on cell proliferation, apoptosis, invasion, and glycolysis were overturned by miR-143-3p deletion. Moreover, FLOT2 was a target gene of miR-143-3p and FLOT2 overexpression rescued the inhibitory effect of miR-143-3p on melanoma progression. Conclusion Circ-FOXM1 facilitated the development of melanoma by upregulating FLOT2 through miR-143-3p.

Abstract
Purpose Colorectal cancer (CRC) is the third most common cancer, and the second leading cause of cancer death worldwide. Dysregulation of microRNAs has been shown to modulate glucose metabolic reprogramming in CRC. However, the functional role of miR-4999-5p in the CRC glucose metabolic shift has not been characterized. Patients and Methods The levels of miR-4999-5p and PRKAA2 were evaluated by RT-qPCR. Univariate and multivariate survival analyses were conducted to evaluate the prognostic value of miR-4999-5p. Cell proliferation was assessed using the CCK-8 and colony formation assays. Extracellular acidification rate, glucose uptake, cellular glucose-6-phosphate level, and lactate production were evaluated to assess the effects of miR-4999-5p on CRC glycolysis. Dual-luciferase reporter assay was conducted to investigate the direct interaction between miR-4999-5p and PRKAA2. Mouse xenograft models were established to assess the functions of miR-4999-5p in vivo. Results miR-4999-5p was highly expressed in CRC tissues and cell lines. In addition, miR-4999-5p was associated with tumor differentiation and TNM stage, and elevated expression of miR-4999-5p was an independent predictor of poorer overall survival. Furthermore, miR-4999-5p promoted cell proliferation and glycolysis in CRC. miR-4999-5p targeted PRKAA2 to exert its tumor-promoting functions, and PRKAA2 knockdown rescued decreased cell proliferation and glycolysis in miR-4999-5p-silenced CRC cells. In vivo experiments showed that miR-4999-5p promoted CRC growth. Conclusion miR-4999-5p facilitated cell growth and glucose metabolic reprogramming through direct targeting of PRKAA2. Our results showed that miR-4999-5p may be a novel prognostic marker and therapeutic target for CRC.

Yang Y, Li S, Cao J, Li Y, Hu H, Wu Z. RRM2 Regulated By LINC00667/miR-143-3p Signal Is Responsible For Non-Small Cell Lung Cancer Cell Progression. Onco Targets Ther 2019; 12:9927-9939. [PMID: 31819489 PMCID: PMC6876211 DOI: 10.2147/ott.s221339] [Citation(s) in RCA: 27] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2019] [Accepted: 10/04/2019] [Indexed: 12/12/2022] Open
Abstract
Background Non-small cell lung cancer (NSCLC) is a common and fatal cancer worldwide with a very low 5-year overall survival rate. Ribonucleotide reductase M2 subunit (RRM2), a small subunit of the ribonucleotide reductase complex, has been found to be an oncogenic role in a variety of tumors including NSCLC. However, the regulatory mechanism of RRM2 in NSCLC is not clear. Increasing evidence suggests that non-coding RNAs (ncRNAs) including miRNAs and lincRNAs may promote or inhibit tumor initiation and development through regulating the expression of oncogenic genes. It is interesting to find ncRNAs which play important role in regulating RRM2 expression. Materials and methods The expression levels of RRM2, LINC0066 and miR-143-3p in NSCLC tumor tissues and cell lines were detected using qRT-PCR. The regulatory relationships among RRM2, LINC0066 and miR-143-3p were predicted using database analysis and verified by luciferase reporter assay and RIP analysis. The proliferation ability of NSCLC cells was assessed using CCK8 and colony formation assays. The expression of related proteins was determined by Western blot. In vivo effect of RRM2, LINC0066 and miR-143-3p to NSCLC were detected through xenograft experiments. Results In this study, we found RRM2 was upregulated in NSCLC tumor and cell lines, and the aberrant upregulation predicted a poor prognosis. Then, we predicted and confirmed that RRM2 was negatively regulated by miR-143-3p. Further study implied that LINC00667 acted as a ceRNA by sponging miR-143-3p and regulated RRM2 expression indirectly. Moreover, we found that the growth of NSCLC was regulated by LINC00667/miR-143-3p/RRM2 signal pathway both in vitro and in vivo. LINC00667 and RRM2 promoted the tumor growth while miR-143-3p inhibited it. Conclusion Our study revealed a LINC00667/miR-143-3p/RRM2 signal pathway that played an important role in the progress of NSCLC, which might be potential therapeutic targets for NSCLC.

[PMID: 31521891 DOI: 10.1016/j.biopha.2019.109424] [Citation(s) in RCA: 37] [Impact Index Per Article: 7.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2019] [Revised: 08/28/2019] [Accepted: 08/31/2019] [Indexed: 12/29/2022] Open
Abstract
BACKGROUND Pancreatic ductal adenocarcinoma (PDAC) is a malignant tumor with high mortality and metastasis, which is difficult to diagnose and treat. MicroRNA-143-3p (miR-143-3p) acts as a tumor suppressor in various cancers. However, its role in pancreatic ductal adenocarcinoma has not been explored. Here we examined the potential role and mechanism of miR-143-3p in PDAC. METHODS The levels of miR-143-3p and KRAS mRNA in matched PDAC and normal tissues as well as PDAC cell lines were determined by quantitative RT-PCR. The effect of miR-143-3p on cell proliferation was evaluated by Cell Counting Kit-8 assay, colony-forming assay and a mouse subcutaneous transplantation model. Transwell assay, wound healing assay and a mouse orthotopic implantation model were conducted to examine the role of miR-143-3p on cell migratory and invasive capacities. The target gene and mechanisms of miR-143-3p were explored by qRT-PCR, western blot and luciferase assays. RESULTS The expression of miR-143-3p was down-regulated in PDAC tissues compared with the paired adjacent normal tissues. Cell proliferative, migratory and invasive capacities in PDAC cells were significantly decreased by miR-143-3p up-regulation. Moreover, we identified KRAS as a direct target of miR-143-3p, revealed its expression to be inversely correlated with miR-143-3p in PDAC samples. Up-regulated expression of KRAS partially reversed the phenotypes induced by miR-143-3p overexpression. What's more, KRAS could activate the ERK signaling pathway, which is associated with tumorigenesis. CONCLUSIONS MiR-143-3p may suppress tumorigenesis in PDAC by targeting KRAS. This might provide a theoretical basis for miR-143-3p in treatment of pancreatic cancer.
