Abstract
Background Detection of cancer in patients with thyroid nodules requires sensitive and specific diagnostic modalities that are accurate and inexpensive. This study aimed to identify a potential microRNA(miRNA) panel to detect papillary thyroid carcinoma (PTC). Methods Following a comprehensive literature review as well as miRNA target predictor databases, Real-time PCR was used to quantify the expression of candidate miRNAs in 59 tissue specimens from 30 patients with PTC and 29 patients with benign nodules. A receiver operating characteristic (ROC) curve analysis was used to assess the accuracy of miRNA expression levels compared to the pathology report as the gold standard. Based on prediction results, four miRNAs, including miR-9, miR-20b, miR-221, and miR-222, were selected to evaluate their expression level in Iranian thyroid samples. Results A significant difference between the tissue expression level of miR-20b, miR-9, miR-222, and miR-221 was detected in the PTC group compared with non-PTC (P < 0.05). The area under the curves for the included miRs were 1, 0.98, 0.99, 0.98, and 1, respectively. Conclusion Our results confirmed deregulations of miR-20b as well as miR-222, miR-221, and miR-9 in PTC and, therefore, could be used as a helpful miRNA panel to differentiate PTC from benign nodules, which results in the more efficient clinical management of PTC patients.

Abstract
CCDC (coiled-coil domain-containing) is a coiled helix domain that exists in natural proteins. There are about 180 CCDC family genes, encoding proteins that are involved in intercellular transmembrane signal transduction and genetic signal transcription, among other functions. Alterations in expression, mutation, and DNA promoter methylation of CCDC family genes have been shown to be associated with the pathogenesis of many diseases, including primary ciliary dyskinesia, infertility, and tumors. In recent studies, CCDC family genes have been found to be involved in regulation of growth, invasion, metastasis, chemosensitivity, and other biological behaviors of malignant tumor cells in various cancer types, including nasopharyngeal carcinoma, lung cancer, colorectal cancer, and thyroid cancer. In this review, we summarize the involvement of CCDC family genes in tumor pathogenesis and the relevant upstream and downstream molecular mechanisms. In addition, we summarize the potential of CCDC family genes as tumor therapy targets. The findings discussed here help us to further understand the role and the therapeutic applications of CCDC family genes in tumors.

Abstract
Colorectal cancer (CRC) is the third most common cancer worldwide. Previous research revealed that microRNA 130b-3p (miR-130b-3p) significantly upregulated in CRC patients can be detected in feces from patients with such a neoplasm. In this study, the biological role and molecular mechanism of miR-130b-3p in CRC were explored. The miR-130b-3p level in CRC tissues, feces and cell lines was measured using RT-qPCR analysis. CCK-8, EdU, TUNEL, flow cytometry, Western blotting, and in vivo experiments were performed to explore the biological function of miR-130b-3p in CRC progression. For this purpose, 16 BALB/c nude mice were assigned to two groups. The experiment lasted for four months. Bioinformatics analysis and luciferase reporter assay were used to investigate the regulatory mechanism related to miR-130b-3p. In our research, miR-130b-3p was upregulated in CRC tissues and cells and it was detected in feces from CRC patients. Moreover, miR-130b-3p inhibition suppressed CRC cell proliferation and promoted cell apoptosis in vitro as well as repressed CRC tumor growth in vivo. Mechanistically, miR-130b-3p directly targeted the 3'untranslated region (UTR) of chromodomain helicase DNA binding protein 9 (CHD9) and negatively regulated CHD9 expression. Furthermore, CHD9 played an anti-oncogenic role in CRC. Inhibition of CHD9 expression was likely to be a key mechanism by which miR-130b-3p increased CRC cell growth, with a target protector experiment revealing miR-130b-3p influenced proliferation via direct inhibition of CHD9. MiR-130b-3p promotes the progression and tumorigenesis of CRC at least partially by targeting CHD9.Abbreviations: CRC: Colorectal cancer; miR-130b-3p: microRNA 130b-3p; CHD9: chromodomain helicase DNA binding protein 9; UTR: untranslated region; FIT: fecal immunochemical test; AAs: advanced adenomas.

Circular RNA circDNA2 upregulates CCDC6 expression to promote the progression of gastric cancer via miR-149-5p suppression. MOLECULAR THERAPY. NUCLEIC ACIDS 2021; 26:360-373. [PMID: 34552818 PMCID: PMC8426470 DOI: 10.1016/j.omtn.2021.05.021] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/11/2020] [Accepted: 05/26/2021] [Indexed: 02/06/2023]
Abstract
Circular (circ)RNAs are widely involved in gastric cancer (GC) pathogenesis, and coiled-coil domain containing 6 (CCDC6) is a fused partner of multiple oncogenes; however, the underlying mechanisms of how circRNAs regulate CCDC6 expression in the progression and prognosis of GC remain unclear. Here, we discovered the circRNA derived from the DNA2 gene locus (circDNA2) through RNA sequencing. By performing quantitative real-time PCR and fluorescence in situ hybridization (FISH) assays with a human tissue microarray, circDNA2 was found to be highly expressed in GC tissues and associated with lymphatic invasion of GC patients. Knockdown of circDNA2 expression suppressed the proliferation of GC cells by reducing CCDC6 expression. Mechanistically, circDNA2 acted as a microRNA (miR)-149-5p sponge, which was confirmed to target CCDC6 by RNA pulldown and dual-luciferase reporter assays and rescue experiments. Both low miR-149-5p expression and high CCDC6 expression were related to unfavorable prognosis in GC patients. Moreover, GC patients with low miR-149-5p expression had shorter overall survival and a higher risk of chemotherapy resistance than those with high miR-149-5p expression. In summary, circDNA2 contributes to the growth and lymphatic metastasis of GC by upregulating CCDC6 expression by sponging miR-149-5p. The circDNA2/miR-149-5p/CCDC6 axis might be developed as a therapeutic target and prognostic indicator for GC.

Abstract
Exosomes are an important carrier for cell communication. miRNAs in exosomes are potential biomarkers and therapeutic targets in different types of cancer. However, the role of exosomal miRNAs in medulloblastoma (MB) patients is largely unknown. In this study, we reported that there was a higher level of miR-130b-3p in exosomes derived from MB patient plasma compared with exosomes from healthy control plasma. Exosomes from MB patient plasma could transfer miR-130b-3p to an MB cell line and played suppressor roles for cell proliferation. miR-130b-3p suppressed MB tumorigenesis by targeting a previously unknown target, serine/threonine-protein kinase 1 (SIK1), through the p53 signaling pathways. In addition, we found an unreported role of SIK1 in promoting MB tumor growth and an SIK1 inhibitor could inhibit MB cell proliferation. This research provides new insight into the molecular mechanism of MB and may provide a new therapeutic strategy for MB treatment.

Abstract
BACKGROUND Diabetes mellitus exacerbates myocardial ischemia/reperfusion (MI/R) injury by incompletely understood mechanisms. Adipocyte dysfunction contributes to remote organ injury. However, the molecular mechanisms linking dysfunctional adipocytes to increased MI/R injury remain unidentified. The current study attempted to clarify whether and how small extracellular vesicles (sEV) may mediate pathological communication between diabetic adipocytes and cardiomyocytes, exacerbating MI/R injury. METHODS Adult male mice were fed a normal or a high-fat diet for 12 weeks. sEV (from diabetic serum, diabetic adipocytes, or high glucose/high lipid-challenged nondiabetic adipocytes) were injected intramyocardially distal of coronary ligation. Animals were subjected to MI/R 48 hours after injection. RESULTS Intramyocardial injection of diabetic serum sEV in the nondiabetic heart significantly exacerbated MI/R injury, as evidenced by poorer cardiac function recovery, larger infarct size, and greater cardiomyocyte apoptosis. Similarly, intramyocardial or systemic administration of diabetic adipocyte sEV or high glucose/high lipid-challenged nondiabetic adipocyte sEV significantly exacerbated MI/R injury. Diabetic epididymal fat transplantation significantly increased MI/R injury in nondiabetic mice, whereas administration of a sEV biogenesis inhibitor significantly mitigated MI/R injury in diabetic mice. A mechanistic investigation identified that miR-130b-3p is a common molecule significantly increased in diabetic serum sEV, diabetic adipocyte sEV, and high glucose/high lipid-challenged nondiabetic adipocyte sEV. Mature (but not primary) miR-130b-3p was significantly increased in the diabetic and nondiabetic heart subjected to diabetic sEV injection. Whereas intramyocardial injection of a miR-130b-3p mimic significantly exacerbated MI/R injury in nondiabetic mice, miR-130b-3p inhibitors significantly attenuated MI/R injury in diabetic mice. Molecular studies identified AMPKα1/α2, Birc6, and Ucp3 as direct downstream targets of miR-130b-3p. Overexpression of these molecules (particularly AMPKα2) reversed miR-130b-3p induced proapoptotic/cardiac harmful effect. Finally, miR-130b-3p levels were significantly increased in plasma sEV from patients with type 2 diabetes mellitus. Incubation of cardiomyocytes with diabetic patient sEV significantly exacerbated ischemic injury, an effect blocked by miR-130b-3p inhibitor. CONCLUSIONS We demonstrate for the first time that miR-130b-3p enrichment in dysfunctional adipocyte-derived sEV, and its suppression of multiple antiapoptotic/cardioprotective molecules in cardiomyocytes, is a novel mechanism exacerbating MI/R injury in the diabetic heart. Targeting miR-130b-3p mediated pathological communication between dysfunctional adipocytes and cardiomyocytes may be a novel strategy attenuating diabetic exacerbation of MI/R injury.

Abstract
Chemotherapeutic drugs that induce DNA damage have the potential to kill cancer cells, but DNA repair protects cells from damage‐induced cell death. Thus, eliminating DNA repair is a potential approach to overcome cell drug resistance. In this study, we observed that the gene expression of C‐terminal binding protein interacting protein (CTIP) was promoted by TNF‐α stimulation and prevented TNF‐α‐induced double‐strand breaks (DSBs) in the genomes of cervical cancer cells. The putative miR‐130b targeted site within 3′ untranslated region (UTR) of CTIP mRNA was identified through in silico analysis and confirmed based on experimental data. By targeting the CTIP gene, miR‐130b caused the accumulation of DSBs and accelerated cell apoptosis in combination with poly ADP ribose polymerase (PARP) inhibitors. Additionally, overexpression of the CTIP gene elevated cancer cell viability by promoting proliferation while miR‐130b antagonized CTIP‐stimulated cell reproduction. Consequently, miR‐130b destruction of DNA repair should be employed as a strategy to treat cervical cancer. Significance of the study Cervical cancer threatens the health of women all over the world. In this study, we observed that miR‐130b was able to cause the accumulation of DNA double‐strand breaks through suppressing the gene expression of C‐terminal binding protein interacting protein and to accelerate cell apoptosis by preventing DNA damage repairs in cervical cancer cells. As far as we know, the impact of miR‐130b on the DNA double‐strand break repair and on the cell apoptosis induced by the destruction of DNA repair in cervical cancer cells was firstly documented. It is reasonable to believe that miR‐130b destruction of DNA repair may be employed as a strategy to treat cervical cancer in the future.

Abstract
The microRNA-146b-5p (miR-146b-5p) is known to be involved in the development of papillary thyroid cancer (PTC); however, the underlying mechanism is unclear. Here we have investigated the biological functions and underlying molecular mechanisms of miR-146b-5p in PTC. The expression of miR-146b-5p was assessed in 92 pairs of PTC and adjacent normal tissues and showed correlation with the clinicopathological status such as the tumour size. Effects of miR-146b-5p and its direct target, coiled-coil domain containing 6 (CCDC6), on cell proliferation, migration, invasion, and cell cycle were evaluated through gain- and loss-of-function studies in vitro and in vivo. The expression of CCDC6 was further examined in 187 PTC cases and was found to be correlated with the clinicopathological status. Overexpression of miR-146b-5p was observed in PTC tissues that correlated with advanced PTC. miR-146b-5p promoted cell proliferation, migration, invasion, and cell cycle progression in vitro, whereas CCDC6 reversed this effect. miR-146b-5p promoted PTC growth in a subcutaneous mouse model in vivo, whereas overexpression of CCDC6 exerted the opposite effect. In conclusion, miR-146b-5p expression correlated with advanced PTC and promoted PTC development by targeting CCDC6 in vitro and in vivo; it could, therefore, serve as a promising target for PTC treatment.

Abstract
Tumour necrosis factor alpha (TNF-α) is a multifunctional cytokine and has the capacity both to promote cell growth and to kill tumour cells by inducing cell apoptosis. However, many tumour cells develop resistance to the toxic effects of TNF-α. Thus, understanding the mechanism underlying the resistance of tumours to TNF-α toxicity and finding ways to overcome this resistance are urgently needed. In this study, we discovered that two cervical cancer cell lines, Hela and Siha, showed null responses to TNF-α cytotoxicity. However, in these cell lines, TNF-α stimulation promoted the expression of miR-130b and downregulated the expression of PTEN gene, which encodes a dual-specificity phosphatase that acts as a tumour suppressor. Blockade of miR-130b function or overexpression of PTEN gene sensitized cells to TNF-α cytotoxicity. Regression analyses revealed that there were reverse relationships between the cellular levels of miR-130b and PTEN mRNA in cervical cancer cells. Gain- and loss-of-function assays demonstrated that there were causal relationships between the increase in miR-130b levels and the reduction in PTEN mRNA or PTEN protein levels. In silico analysis revealed that there were two miR-130b target sites within the 3'UTR of PTEN mRNA and experimental evidences demonstrated that miR-130b repressed the expression of PTEN gene by binding directly to the 3'UTR of PTEN mRNA. These data suggest miR-130b expression as a target to be inhibited to make tumour cells more sensitive to the toxic impact of TNF-α.

De Martino M, Palma G, Azzariti A, Arra C, Fusco A, Esposito F. The HMGA1 Pseudogene 7 Induces miR-483 and miR-675 Upregulation by Activating Egr1 through a ceRNA Mechanism. Genes (Basel) 2017; 8:genes8110330. [PMID: 29149041 PMCID: PMC5704243 DOI: 10.3390/genes8110330] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2017] [Revised: 11/08/2017] [Accepted: 11/09/2017] [Indexed: 02/06/2023] Open
Abstract
Several studies have established that pseudogene mRNAs can work as competing endogenous RNAs and, when deregulated, play a key role in the onset of human neoplasias. Recently, we have isolated two HMGA1 pseudogenes, HMGA1P6 and HMGA1P7. These pseudogenes have a critical role in cancer progression, acting as micro RNA (miRNA) sponges for HMGA1 and other cancer-related genes. HMGA1 pseudogenes were found overexpressed in several human carcinomas, and their expression levels positively correlate with an advanced cancer stage and a poor prognosis. In order to investigate the molecular alterations following HMGA1 pseudogene 7 overexpression, we carried out miRNA sequencing analysis on HMGA1P7 overexpressing mouse embryonic fibroblasts. Intriguingly, the most upregulated miRNAs were miR-483 and miR-675 that have been described as key regulators in cancer progression. Here, we report that HMGA1P7 upregulates miR-483 and miR-675 through a competing endogenous RNA mechanism with Egr1, a transcriptional factor that positively regulates miR-483 and miR-675 expression.

BMC Cancer 2017; 17:170. [PMID: 28259135 PMCID: PMC5336640 DOI: 10.1186/s12885-017-3158-z] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2016] [Accepted: 02/24/2017] [Indexed: 12/31/2022] Open
Abstract
Background Loss of CBX7 expression has been described in several malignant neoplasias, including human colon and thyroid carcinomas proposing CBX7 as a tumor suppressor gene with a key role in cancer progression. This role is supported from the development of benign and malignant neoplasias in Cbx7 null mice. The aim of our work has been to investigate the mechanisms underlying the CBX7 oncosuppressor activity by analyzing the microRNAs (miRNAs) regulated by CBX7. Methods The miRNA expression profiles of the mouse embryonic fibroblasts (MEFs) null for Cbx7 and the wild-type counterpart were analyzed by the miRNACHIP microarray and then validated by qRT-PCR. To asses KRAS as target of miR-155 we evaluated the protein levels after transfection of the synthetic miR-155. Human colon carcinoma samples have been investigated for the expression of CBX7 and miR-155. Results Twenty miRNAs were found upregulated and nine, including miR-155, downregulated in cbx7-null MEFS in comparison with the wild-type ones. Then, we focused on miR-155 since several studies have shown its deregulated expression in several human malignancies and, moreover, was the most downregulated miRNA. Subsequently, we searched for miR-155 target genes demonstrating that KRAS protein levels are directly modulated by miR-155. A direct significant correlation (r = 0.6779) between CBX7 and miR-155 expression levels was found in a set of human colon carcinoma tissue samples. Conclusion miR-155 is positively regulated by CBX7 in MEFs and colon carcinomas, and has KRAS as one of the target genes likely accounting for the anti-apoptotic activity ascribed to miR-155 in some tissue contexts.
