Cím:Suppressing the PI3K/AKT Pathway by miR-30d-5p Mimic Sensitizes Ovarian Cancer Cells to Cell Death Induced by High-Dose Estrogen / Varga Alexandra, Márton Éva, Markovics Arnold, Penyige András, Balogh István, Nagy Bálint, Szilágyi Melinda

Megjegyzések:MicroRNAs are short non-coding RNA molecules that are involved in tumor development and are considered to be promising candidates in cancer therapy. Here, we studied the role of miR-30s in the pathophysiology of ovarian cancer. According to our results miR-30a-5p, miR-30d-5p, and miR-30e-5p were overexpressed in the estrogen receptor alpha (ER alpha)-expressing PEO1 cell line compared to A2780 that lacks this receptor. Furthermore, the expression of miR-30a-5p, miR-30d-5p, and miR-30e-5p were induced in response to high-dose estrogen treatment in PEO1 where intensive cell death was observed according to the induction of apoptosis and autophagy. Lacking or blocking ER alpha function reduced tolerance to high-dose estrogen that suggests the importance of ER alpha-mediated estrogen response in the maintenance of proliferation. MiR-30d-5p mimic reduced cell proliferation in both A2780 and PEO1. Furthermore, it decreased the tolerance of PEO1 cells to high-dose estrogen by blocking the ER alpha-mediated estrogen response. This was accompanied by decreased SOX4 expression that is thought to be involved in the regulation of the PI3K/AKT pathway. Blocking this pathway by AZD8835 led to the same results. MiR-30d-5p or AZD8835 sensitized PEO1 cells to tamoxifen. We suggest that miR-30d-5p might be a promising candidate in the therapy of ovarian cancer.

Megjegyzések:Background: Glioblastoma multiforme (GBM) is among the most aggressive cancers with a poor prognosis. Treatment options are limited, clinicians lack efficient prognostic and predictive markers. Circulating miRNAs?besides being important regulators of cancer development?may have potential as diagnostic biomarkers of GBM. (2) Methods: In this study, profiling of 798 human miRNAs was performed on blood plasma samples from 6 healthy individuals and 6 patients with GBM, using a NanoString nCounter Analysis System. To validate our results, five miRNAs (hsa-miR-433-3p, hsa-miR-362-3p, hsa-miR-195-5p, hsa-miR-133a-3p, and hsa-miR-29a-3p) were randomly chosen for RT-qPCR detection. (3) Results: In all, 53 miRNAs were significantly differentially expressed in plasma samples of GBM patients when data were filtered for FC 1 and FDR 0.1. Target genes of the top 39 differentially expressed miRNAs were identified, and we carried out functional annotation and pathway enrichment analysis of target genes via GO and KEGG-based tools. General and cortex-specific protein?protein interaction networks were constructed from the target genes of top miRNAs to assess their functional connections. (4) Conclusions: We demonstrated that plasma microRNA profiles are promising diagnostic and prognostic molecular biomarkers that may find an actual application in the clinical practice of GBM, although more studies are needed to validate our results.

Megjegyzések:Ovarian tumor is one of the leading causes of cancer among women. Patients are diagnosed at an advanced stage, usually. There is a need for new specific and sensitive biomarkers. Mitochondrial DNA copy number change was observed in various cancers. Our aim was to detect mitochondrial DNA copy number in whole blood (wb-mtDNA) and in plasma (cell-free and exosome encapsulated mtDNA) in patients with serous epithelial ovarian tumor. DNA was isolated from EDTA blood and plasma obtained from 24 patients and 24 healthy controls. Exosomes were isolated from cell-free plasma, and exosome encapsulated DNA (exoDNA) was extracted. Quantitative-real-time PCR was performed with Human Mitochondrial DNA (mtDNA) Monitoring Primer Set. Kruskall?Wallis and Mann?Whitney U test were used for data analysis. Wb-mtDNA copy number was significantly different among healthy controls and patients in multiple comparison (p?=?0.0090 considering FIGO stage independently, and p?=?0.0048 considering early- and late-stage cancers). There was a significant decrease among early-stage, all advanced stage and all cancer patients (FIGO I: 32.5?±?8.3, p?=?0.0061; FIGO III?+?IV: 37.2?±?13.7 p?=?0.0139; FIGO I?+?III?+?IV: 35.6?±?12.2, p?=?0.0017) or FIGO III patients alone (32.8?±?5.6, p?=?0.00089) compared to healthy controls. We found significant increase in copy number in exosomal mtDNA in cancer patients (236.0?±?499.0, p?=?0.0155), advanced-stage cancer patients (333.0?±?575.0, p?=?0.0095), of FIGO III (362.0?±?609.2, p?=?0.0494), and FIGO IV (304.0?±?585.0, p?=?0.0393) patients alone but not in samples of FIGO I patients (10.0?±?3.5, p?=?0.3907). In multiple comparison the increase was significant considering early- and late-stage cancers (p?=?0.0253). Cell-free mtDNA copy numbers were not increased significantly. We found the highest copy number of mtDNA in exosomes, followed by plasma and peripheral blood in late-stage cancer patients. We observed significant difference in wb-mtDNA copy number between healthy controls and both early- and late-stage cancer patients.

Megjegyzések:Introduction: miRNA molecules are short, non-coding sequences regulating gene expression after transcription. They are important in the development, progression and treatability of tumours. Single Nucleotide Polymorphism (SNP) is the most frequent type of genetic polymorphism. That is true also for miRNAs and their polymorphisms can cause alterations in the gene expression profile. miR-196a was also linked to the genesis of different tumours.Aim: Search for correlation between miR-196a polymorphism and development of ovarian cancer.Materials and Methods: 75 patients with ovarian cancer and 75 healthy persons were investigated. 15-16 mL blood anticoagulated with EDTA was drawn. DNA was isolated with silica absorption method and the melting curve of PCR products generated with LightSnip kit (TibMolbiol, Berlin, Germany) developed for miR-196a (rs11614913) SNP was determined by LightCycler 96 equipment. Allele and genotype frequencies were specified and Student t-test was applied for statistical analysis of data.Results: The Tm of PCR products were 55.5?C for T allele and 62.6?C for C allele with melting-curve analysis. T allele occurred in 32.66% in population of patients and in 40.66% in control group. Genotypes among control persons were 18.66% for TT, 44.0% for TC, and 37.33% CC, while in case of patients these frequencies were 12.0%, 41.33%, and 46.66%, respectively (p=0.3815).Conclusion: miR-196a influences the expression of 684 genes, it requires further complex investigation, whether it is involved in the development of ovarian cancer.

Megjegyzések:MicroRNAs play an essential role in the regulation of gene expression and tumor development. Single nucleotide polymorphism (SNP) can be observed in miRNAs and could influence gene expression. We aimed to identify miR-146a rs2910164 and miR-196a-2 rs11614913 polymorphisms in ovarian cancer patients and controls. 75 patients and 75 controls were involved. DNA was isolated from blood samples. MiR-146a rs2910164 and miR-196a-2 rs11614913 were determined by LightSnip kit. We used melting curve analysis for allele classification. Network analysis was made to find common target genes. We detected 72.67% G allele frequency of miR-146a rs2910164 in controls and 82.00% in patients group (p?=?0,053). GG, GC and CC genotypes occurred with 53.33%, 38.67% and 8.00% among controls, with 65.33%, 33.33% and 1.33% among patients, (p?=?0.0917). Allele C of miR-196a-2 rs11614913 occurred in 59.33% of controls and in 67.33% of patients (p?=?0.15). CC, CT and TT genotypes occurred with 37.33%, 44.00%, and 18.67% frequency in controls, with 46.67%; 41.33% and 12.00% in patients (p?=?0.3815). Network analysis found ATG9A, LBR, MBD4 and RUFY2 genes to be targets for both miRNAs. SNPs of miR-146a and miR-196a-2 showed no significant differences between patients and controls. More investigations are required to clarify the exact role of these SNPs in ovarian cancer.

Cím:Comparative Analysis of Transcriptomic Changes including mRNA and microRNA Expression Induced by the Xenoestrogens Zearalenone and Bisphenol A in Human Ovarian Cells / Éva Márton, Alexandra Varga, András Penyige, Zsuzsanna Birkó, István Balogh, Bálint Nagy, Melinda Szilágyi

ISSN:2072-6651
Megjegyzések:Xenoestrogens are natural or synthetic compounds that mimic the effect of endogenous estrogens and might cause cancer. We aimed to compare the global transcriptomic response to zearalenone (ZEA; mycotoxin) and bisphenol A (BPA; plastic additive) with the effect of physiological estradiol (E2) in the PEO1 human ovarian cell line by mRNA and microRNA sequencing. Estrogen exposure induced remarkable transcriptomic changes: 308, 288 and 63 genes were upregulated (log2FC > 1); 292, 260 and 45 genes were downregulated (log2FC < ?1) in response to E2 (10 nM), ZEA (10 nM) and BPA (100 nM), respectively. Furthermore, the expression of 13, 11 and 10 miRNAs changed significantly (log2FC > 1, or log2FC < ?1) after exposure to E2, ZEA and BPA, respectively. Functional enrichment analysis of the significantly differentially expressed genes and miRNAs revealed several pathways related to the regulation of cell proliferation and migration. The effect of E2 and ZEA was highly comparable: 407 genes were coregulated by these molecules. We could identify 83 genes that were regulated by all three treatments that might have a significant role in the estrogen response of ovarian cells. Furthermore, the downregulation of several miRNAs (miR-501- 5p, let-7a-2-3p, miR-26a-2-3p, miR-197-5p and miR-582-3p) was confirmed by qPCR, which might support the proliferative effect of estrogens in ovarian cells.

Cím:Comparative Analysis of Cell-Free miR-205-5p, let-7f-5p, and miR-483-5p Expression in Ovarian Cell Cultures and Plasma Samples of Patients with Ovarian Cancer / Éva Márton, Alexandra Varga, Beáta Soltész, András Penyige, János Lukács, Róbert Póka, Bálint Nagy, Melinda Szilágyi
Dátum:2021
Megjegyzések:The term liquid biopsy reveals a non-invasive diagnostic method that might be based on the quantification of cell-free microRNAs in body fluids. However, the identification of candidates for liquid biopsy is challenging. Our aim was to compare the cell-free expression of miR-483-5p, miR-205-5p, and let-7f-5p in ovarian cell cultures and plasma samples of patients with ovarian cancer. Both the intracellular and cell-free expression of miR-205-5p and let-7f-5p proved to be higher in the Estrogen Receptor ? (ER?) expressing PEO1 cell-line than in the estrogen non-sensitive A2780. Moreover, the expression of let-7f-5p was up-regulated in response to estradiol exposure that was diminished after the addition of an ER? selective antagonist. MiR-483-5p had lower intracellular and cell-free expression in PEO1. All these miRNAs had detectable expression level in plasma samples, among which miR-205-5p proved to be overexpressed in the plasma samples of patients with ovarian tumors compared to healthy controls and possessed an acceptable diagnostic potential with ROC-AUC 0.683 (95% CI 0.57?0.795). Functional annotation clustering of the target genes of miR-205-5p revealed several clusters involved in cancer development. We suggest that miR-205-5p might be a promising biomarker candidate in ovarian cancer that should be further analyzed in larger sample size.

Cím:The Cell-Free Expression of MiR200 Family Members Correlates with Estrogen Sensitivity in Human Epithelial Ovarian Cells / Éva Márton, Alexandra Varga, Lajos Széles, Lóránd Göczi, András Penyige, Bálint Nagy, Melinda Szilágyi

Megjegyzések:Exposure to physiological estrogens or xenoestrogens (e.g., zearalenone or bisphenol A) increases the risk for cancer. However, little information is available on their significance in ovarian cancer. We present a comprehensive study on the effect of estradiol, zearalenone and bisphenol A on the phenotype, mRNA, intracellular and cell-free miRNA expression of human epithelial ovarian cell lines. Estrogens induced a comparable effect on the rate of cell proliferation and migration as well as on the expression of estrogen-responsive genes (GREB1, CA12, DEPTOR, RBBP8) in the estrogen receptor ? (ER?)-expressing PEO1 cell line, which was not observable in the absence of this receptor (in A2780 cells). The basal intracellular and cell-free expression of miR200s and miR203a was higher in PEO1, which was accompanied with low ZEB1 and high E-cadherin expression. These miRNAs showed a rapid but intermittent upregulation in response to estrogens that was diminished by an ER?-specific antagonist. The role of ER? in the regulation of the MIR200B-MIR200A-MIR429 locus was further supported by publicly available ChIP-seq data. MiRNA expression of cell lysates correlated well with cell-free miRNA expression. We conclude that cell-free miR200s might be promising biomarkers to assess estrogen sensitivity of ovarian cells.

Megjegyzések:Ovarian cancer is the fifth most common cause of cancer death among women that is mostly due to the difficulty of early diagnosis. Circulating miRNAs proved to be reliable biomarkers in various cancers. We screened 9 miRNAs, which are involved in epithelial-mesenchymal transition, in the plasma samples of patients with malignant (n=28) or non-malignant (n=12) ovarian tumors and disease-free healthy volunteers (n=60) by qRT-PCR. The expression levels of miR200a, miR200b, miR200c, miR141, miR429, miR203a, miR34b (p<0.001) and miR34a (p<0.01) were significantly higher in the malignant samples than in healthy controls. MiR203a, miR141 (p<0.01), miR200a and miR429 (p<0.05) levels were also higher in malignant compared to non-malignant samples. ROC-AUC was the highest in the case of miR200c: 0.861 (95%CI=0.776-0.947). Spearman's rank correlation analysis revealed positive correlation between the plasma levels of the studied miRNAs that was the highest between miR200b and miR200c (rs = 0.774; p<0.001). Target analysis also suggested tight interaction between these miRNAs in the regulation of cancer development. The agreement of diagnostic tests based on miRNA levels and the standard CA125 or HE4 was weak according to Cohen's kappa values.

Megjegyzések:Ovarian cancer is one of the most common cancer types in women characterized by a high mortality rate due to lack of early diagnosis. Circulating miRNAs besides being important regulators of cancer development could be potential biomarkers to aid diagnosis. We performed the circulating miRNA expression analysis in plasma samples obtained from ovarian cancer patients stratified into FIGO I, FIGO III, and FIGO IV stages and from healthy females using the NanoString quantitative assay. Forty-five miRNAs were di erentially expressed, out of these 17 miRNAs showed significantly di erent expression between controls and patients, 28 were expressed only in patients, among them 19 were expressed only in FIGO I patients. Di erentially expressed miRNAs were ranked by the network-based analysis to assess their importance. Target genes of the di erentially expressed miRNAs were identified then functional annotation of the target genes by the GO and KEGG-based enrichment analysis was carried out. A general and an ovary-specific protein?protein interaction network was constructed from target genes. Results of our network and the functional enrichment analysis suggest that besides HSP90AA1, MYC, SP1, BRCA1, RB1, CFTR, STAT3, E2F1, ERBB2, EZH2, and MET genes, additional genes which are enriched in cell cycle regulation, FOXO, TP53, PI-3AKT, AMPK, TGF , ERBB signaling pathways and in the regulation of gene expression, proliferation, cellular response to hypoxia, and negative regulation of the apoptotic process, the GO terms have central importance in ovarian cancer development. The aberrantly expressed miRNAs might be considered as potential biomarkers for the diagnosis of ovarian cancer after validation of these results in a larger cohort of ovarian cancer patients.

Megjegyzések:CD24 is a small molecular weight cell-surface protein and an independent marker for poor prognosis in the different type of cancers. We aimed to determine the expression of CD24 in plasma, exosomes and ovarian tissue samples of serous ovarian cancer patients. We collected tissue and blood samples from 21 cases of serous ovarian cancer and eight healthy controls. We used silica adsorption method for isolation of RNA. The cDNA was synthesized using quantitative real-time PCR. We used beta-globin as a housekeeping gene for the normalization of the data. Protein-protein and miRNA networking were analyzed. There was a significant difference in the expression of CD24 in ovarian tissue between controls and patients (0.16?±?0.32 vs. 44.97?±?68.06; p?<?0.01), while CD24 did not show expression in each plasma and exosome samples. There was a correlation in the expression of CD24 and FIGO grading between controls and patients. CD24 expression was detected in exosomes in 38.1% of patients, mainly with FIGO III, and in their plasma in 9.5% of cases. Our network analysis shows LYN, SELP, FGR, and NPM1 proteins are interacting with CD24. Our study demonstrates higher expression of CD24 in ovarian cancer patients' tissue samples, and there is an association with FIGO classification. However, CD24 showed expression only in some cell-free plasma and exosome samples.
