Insights into the genetic and epigenetic mechanisms governing X-chromosome-linked-miRNAs expression in cancer; a step-toward ncRNA precision. Int J Biol Macromol 2025; 289:138773. [PMID: 39675615 DOI: 10.1016/j.ijbiomac.2024.138773] [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: 12/04/2024] [Revised: 12/09/2024] [Accepted: 12/11/2024] [Indexed: 12/17/2024]
Abstract
Sex chromosomes play a significant role in establishing sex-specific differences in gene expression, thereby contributing to phenotypic diversity and susceptibility to various diseases. MicroRNAs (miRNAs), which are small non-coding RNAs encoded by both the X and Y chromosomes, exhibit sex-specific regulatory characteristics. Computational analysis has identified several X-linked miRNAs differentially expressed in sex-specific cancers. This review aims to elucidate the genetic and epigenetic mechanisms that govern the sex-specific expression of X- and Y-linked miRNAs, with particular attention to their functional role in regulating diverse cellular processes in different cancer pathways. In addition, this review provides a comprehensive understanding of the targeted therapeutic interventions and critical insights into the potential clinical implications of targeting sex-specific miRNAs. In conclusion, this review opens new horizons for further research to effectively translate these findings into viable treatment options.

Abstract
Background MicroRNAs (miRNAs) play pivotal roles in post-transcriptional regulation of gene expression and have emerged as crucial regulators in cancer development, progression, and metastasis. This study aimed to assess the expression profiles of miR-23, miR-223, miR-1246, and miR-150 in serum samples obtained from colorectal cancer (CRC) patients before and three months after surgery, in comparison to a healthy control group, to explore their biomarker potential. Methods A total of 50 blood samples were collected from patients with CRC (pre- and post-surgery), along with 50 samples from healthy controls. The relative expression levels of miR-23, miR-223, miR-1246, and miR-150 in the serum were quantified using quantitative real-time PCR. Results Our findings revealed upregulated expression levels of miR-23, miR-1246, and miR-223, while miR-150 exhibited significant downregulation in the serum of CRC subjects compared to healthy controls. Receiver operating characteristic (ROC) analysis indicated that miR-23 and miR-150 could distinguish CRC cases from controls with relatively high accuracy. Moreover, three months post-surgery, miR-23, miR-1246, and miR-223 serum levels were downregulated, and miR-150 was significantly upregulated. However, no significant correlations were observed between serum levels of the studied genes and the clinical features of our patients. Conclusions The serum levels of miR-23 and miR-150 hold promise as potential biomarkers for the diagnosis and prognosis of CRC.

Abstract
Background Colorectal cancer is a heterogeneous disease that leads to metabolic disorders due to multiple upstream genetic and molecular changes and interactions. The development of new therapies, especially herbal medicines, has received much global attention. Dorema ammoniacum is a medicinal plant. Its gum is used in healing known ailments. Studying metabolome profiles based on nuclear magnetic resonance 1HNMR as a non-invasive and reproducible tool can identify metabolic changes as a reflection of intracellular fluxes, especially in drug responses. This study aimed to investigate the anti-cancer effects of different gum extracts on metabolic changes and their impact on gene expression in HT-29 cell. Methods Extraction of Dorema ammoniacum gum with hexane, chloroform, and dichloromethane organic solvents was performed. Cell inhibition growth percentage and IC50 were assessed. Following treating the cells with dichloromethane extract, p53, APC, and KRAS gene expression were determined. 1HNMR spectroscopy was conducted. Eventually, systems biology software tools interpreted combined metabolites and genes simultaneously. Results The lowest determined IC50 concentration was related to dichloromethane solvent, and the highest was hexane and chloroform. The expression of the KRAS oncogene gene decreased significantly after treatment with dichloromethane extract compared to the control group, and the expression of tumor suppressor gene p53 and APC increased significantly. Most gene-altered convergent metabolic phenotypes. Conclusion This study's results indicate that the dichloromethane solvent of Dorema ammoniacum gum exhibits its antitumor properties by altering the expression of genes involved in HT-29 cells and the consequent change in downstream metabolic reprogramming.

Abstract
Background Colorectal cancer (CRC) is considered the third most common cancer around the world and second in terms of mortality. A significant aspect in its development is genetics. The risk of CRC and other clinicopathologic characteristics were investigated in this work in relation to the long non-coding RNA (lncRNA) MEG3 rs7158663 polymorphism, MEG3 expression, in an Egyptian population. Methods 160 CRC patients and 160 healthy controls were enrolled in this case-control study. The lncRNA MEG3 rs7158663 was examined using TaqMan Real-time PCR. RT-PCR was used to assess the levels of serum MEG3 expression. Results A significant higher expression of 'A' allele (risk allele) and A/A genotype in CRC cases vs. control subjects (P <0.001) Participants with A/A genotype had 4.8 times higher odds to exhibit CRC. Serum MEG3 gene expression was generally low in CRC patients, and it was considerably lower in those with the rs7158663 AA genotype than those with the GG genotype (P <0.001). It was found that CRC patients with the rs7158663 GA genotype had lower serum MEG3 expression levels than those with the GG genotype (P <0.001). Conclusions MEG3 low expression and MEG3 rs7158663 (AA) were associated with CRC risk in Egyptian patients and may serve as a diagnostic and prognostic marker for CRC patients.

Abstract
Background Non-alcoholic fatty liver disease is a major problem worldwide that needs non-invasive biomarkers for early diagnosis and treatment response assessment. We aimed to assess the correlation between circRNA-HIPK3 and miRNA-29a expression and its role as miRNA-29a sponge, as well as the correlation between circRNA-0046367 and miRNA-34a expression and its role as miRNA-34a sponge and their effect on regulation of the Wnt/β catenin pathway, which may provide a new target for treatment of non-alcoholic steatohepatitis. Methods the research was performed on 110 participants: group (I): fifty-five healthy donors served as controls and group (II): fifty-five patients with fatty liver pattern on abdominal ultrasound. Lipid profile and liver functions were assessed. RT-PCR was performed to assess the RNAs: circRNA-HIPK3, circRNA-0046367, miRNA-29a, miRNA-34a and Wnt mRNA gene expression. ELISA was performed to determine β-catenin protein levels. Results miRNA-34a and circRNA-HIPK3 expression were significantly greater, while miRNA-29a and circRNA-0046367 expression were significantly less, in patients than in controls. Wnt/β-catenin regulated by miRNA-29a and miRNA-34a showed a significant decrease that leads to its abnormal effect on lipid metabolism. Conclusions our results imply that miRNA-29a can be investigated as a target for circRNA-HIPK3, while miRNA-34a can be investigated as a target for circRNA-0046367, and that circRNA-HIPK3 and circRNA-0046367 may have emerging roles that can affect the pathogenesis of nonalcoholic steatohepatitis through the Wnt/β-catenin pathway and thus be used as therapeutic targets for the disease.

Abstract
Background Colorectal cancer (CRC) is still considered one of the prevalent cancers worldwide. Investigation of potential biomarkers for early detection of CRC is essential for the effective management of patients using therapeutic strategies. Considering that, this study was aimed to examine the changes in lncRNA FOXD2-AS1 expression through colorectal tumorigenesis. Methods Fifty CRC tumor tissues and fifty adjacent normal tissue samples were prepared and involved in the current study. Total RNA was extracted from the samples and then reverse transcribed to complementary DNA. Next, the expression levels of lncRNA FOXD2-AS1 were evaluated using real-time PCR in CRC samples compared to normal ones. Also, receiver operating characteristic curve analysis was used to evaluate the diagnostic value of FOXD2-AS1 for CRC. Results The obtained results showed that the expression level of FOXD2-AS1 gene was significantly (p<0.0001) up-regulated in tumor tissues compared to normal marginal tissues. Also, a significant correlation was observed between higher the expression of FOXD2-AS1and the differentiation of tumor cells. Furthermore, ROC curve analysis estimated an AUC value of 0.59 for FOXD2-AS1, suggesting its potential as a diagnostic target. Conclusion Taken together, the current study implied that tissue-specific upregulation of lncRNA FOXD2-AS1 might be appropriate diagnostic biomarkers for CRC. Nonetheless, more studies are needed to validate these results and further illustrate FOXD2-AS1 function through colorectal tumorigenesis.

Abstract
Background: MicroRNAs (miRNAs) are small RNA molecules involved in the control of the expression of many genes and are responsible for, among other things, cell death, differentiation and the control of their division. Changes in miRNA expression profiles have been observed in colorectal cancer. This discovery significantly enriches our knowledge of the pathogenesis of colorectal cancer and offers new goals in diagnostics and therapy. Aim: The aim of this study was to analyze the expression of four miRNA sequences—miR-143, miR-1, miR-210 and let-7e—and to investigate their significance in the risk of developing colorectal cancer. Materials and methods: miRNA sequences were investigated in formalin-fixed, paraffin-embedded (FFPE) tissue in colorectal cancer patients (n = 150) and in cancer-free controls (n = 150). The real-time PCR method was used. Results: This study revealed a lower expression of miR-143 in colorectal cancer patients than in the controls. miR-143 was positively correlated with the degree of tumor differentiation (grading). Three out of four analyzed miRNA (miR-1, miR-210 and let-7e) were found to be statistically insignificant in terms of colorectal carcinoma risk. Conclusions: miR-143 may be associated with the development of colorectal cancer.

Abstract
BACKGROUND Current cancer treatments include surgery, radiotherapy, chemotherapy, and immunotherapy. Despite these treatments, a main issue in cancer treatment is early detection. microRNAs (miRNAs) can be used as markers to diagnose and treat cancers. This study investigated the effect of radiotherapy on miR-374 expression, and APC and GSK-3β, two of its target genes, in the WNT pathway, in peripheral blood samples from radiotherapy-treated colorectal cancer (CRC) patients. METHODS Peripheral blood was collected from 25 patients before and after radiotherapy. RNA was extracted from the blood and cDNA synthesized. miR-374, APC, and GSK-3β expression was determined by real-time polymerase chain reaction (RT-PCR) and the amplicons were sequenced. Finally, the data were statistically evaluated. RESULTS Quantitative RT-PCR revealed significant down-regulation of miR-374 (0.63-fold) and up-regulation of APC (1.12-fold) and GSK-3β (1.22-fold) in CRC patients after five weeks of radiotherapy. Sequencing of PCR-produced amplicons confirmed the conservation of mature and precursor sequences encoding miR-374. miR-374 expression changed with time after radiotherapy treatment and related tumor grading. Increased age and tumor grade positively correlated with decreased miR-374 expression. CONCLUSION miR-374 expression, and that of its two target genes, APC and GSK-3β, changed after radiotherapy. These genes can likely be used as diagnostic radiotherapy markers in CRC.

Abstract
BACKGROUND MicroRNA expression signature and reactive oxygen species (ROS) production have been associated with the development of cardiovascular diseases (CVDs). This study aimed to evaluate oxidative stress, inflammation, apoptosis, and the expression of miRNA-208a and miRNA-1 in cardiovascular patients. METHODS The study population included four types of patients (acute coronary syndromes (ACS), myocardial infarction (MI), arrhythmia, and heart failure (HF)), with 10 people in each group, as well as a control group. Quantitative real-time PCR was performed to measure mir-208 and miR-1 expression, the mRNAs of inflammatory mediators (TNFα, iNOS/eNOS), and apoptotic factors (Bax and Bcl2). XOX, MDA, and antioxidant enzymes (CAT, SOD, and GPx) were measured by ZellBio GmbH kits by an ELISA Reader. RESULTS The results showed significant decreases in the activity of antioxidant enzymes (CAT, SOD, and Gpx) and a significant increase in the activity of the MDA and XOX in cardiovascular patients. Significant increases in IL-10, iNos, iNOS / eNOS, and TNF-α in cardiovascular patients were also observed. Also, a significant increase in the expression of miR-208 (HF> arrhythmia> ACS> MI) and a significant decrease in the expression of miR-1 (ACS> arrhythmia> HF> MI) were found in all four groups in cardiovascular patients. CONCLUSION The results showed increases in oxidative stress, inflammation, apoptotic factors, and in the expression of miR-208a in a variety of cardiovascular patients (ACS, MI, arrhythmia, and HF). It is suggested that future studies determine the relationships that miR-1, miR-208, and oxidative stress indices have with inflammation and apoptosis.

Abstract
Background Chronic lymphocytic leukemia (CLL) is one of the most prevalent forms of leukemia in adults. Inactivation of the DLEU7 gene is frequently observed in patients with CLL. Furthermore, microRNAs (miRNAs) have been observed to have a critical role in the pathogenesis of several cancers, including leukemia. Considering the tumor-suppressive role of DLEU7, as well as the tumor suppressor or oncogenic role of microRNAs (miRNAs), the aim of the present study was to evaluate the potential miRNAs targeting the DLEU7 gene in B-cells and explore expression changes these genes in the plasma of B-CLL patients. Methods The miRNAs interacting with the DLEU7 gene were predicted and selected using bioinformatics tools. A total of 80 plasma samples were collected from 40 patients with B-cells and 40 healthy individuals, then subjected to RNA extraction and cDNA synthesis. The expression profiles of the predicted miRNAs and the DLEU7 gene in the plasma of B-CLL patients and healthy individuals were determined by RT-qPCR analysis. Results The bioinformatics prediction indicated that miR-15b and miR-195 target the DLEU7 gene. The expression levels of miR-15b and miR-195 were significantly higher in the plasma of patients with B-CLL compared to the healthy individuals (91.6, p= 0.001) (169, p= 0.001). However, the expression level of the DLEU7 gene was found to be significantly lower in the patient group compared to healthy controls (0.304, p= 0.001). Conclusion Both miR-15b and miR-195, have the potential to function as novel and non-invasive biomarkers in the diagnosis and prognosis of patients with B-CLL.
