HOTAIR in cancer: diagnostic, prognostic, and therapeutic perspectives.

The long non-coding RNA HOTAIR is overexpressed in many cancers and is associated with several cancer-promoting effects, including increased cell proliferation, migration and treatment resistance. HOTAIR levels correlate with tumor stage, lymph node metastasis and overall survival in patients with various types of cancer. This highlights the potential uses of HOTAIR, including early cancer detection, predicting patient outcome, identifying high-risk individuals and assisting in therapy selection and monitoring.

Circular RNAs: novel noncoding players in male infertility.

Infertility is a global problem being associated with emotional and financial burden. Recent studies have shown contribution of a group of non-coding RNAs, namely circular RNAs (circRNAs) to the etiology of some infertility conditions. CircRNA are transcribed from exons and form a circular RNA molecule, being abundant in eukaryotes.

The role of mir-214-5p and mir-548-5p expressions in endometriosis.

Background: Endometriosis is a benign gynecological disease that affects about 1% of all women and up to 15% of women of childbearing age. To date, none of the proposed theories exhaustively explain the pathophysiology of the disease or the associated clinical manifestations. As part of efforts to introduce new methods for the early and non-invasive diagnosis of endometriosis, this project investigated changes in the expression of miR-214-5p and miR-548-5p in ectopic and eutopic tissue compared to normal endometrial tissue.

Where do obesity and male infertility collide?

The parallel rise in obesity and male infertility in modern societies necessitates the identification of susceptibility genes underlying these interconnected health issues. In our study, we conducted a comprehensive search in the OMIM database to identify genes commonly associated with male infertility and obesity. Subsequently, we performed an insilico analysis using the REVEL algorithm to detect pathogenic single nucleotide polymorphisms (SNPs) in the coding region of these candidate genes.

Biomarker Profile of Colorectal Cancer: Current Findings and Future Perspective.

Objective: Breakthroughs in omics technology have led to a deeper understanding of the fundamental molecular changes that play a critical role in the development and progression of cancer. This review delves into the hidden molecular drivers of colorectal cancer (CRC), offering potential for clinical translation through novel biomarkers and personalized therapies.

Methods: We summarizes recent studies utilizing various omics approaches, including genomics, transcriptomics, proteomics, epigenomics, metabolomics and data integration with computational algorithms, to investigate CRC.

Circular RNAs in renal cell carcinoma: from mechanistic to clinical perspective.

CircRNAs, a special type of noncoding RNAs characterized by their stable structure and unique abilities to form backsplicing loops, have recently attracted the interest of scientists. These RNAs are abundant throughout the body and play important roles such as microRNA sponges, templates for transcription, and regulation of protein translation and RNA-binding proteins. Renal cancer development is highly correlated with abnormal circRNA expression in vivo.

Association of miR-146a and miR196a2 genotype with susceptibility to idiopathic recurrent pregnancy loss in Iranian women: A case-control study.

Background: Recurrent pregnancy loss (RPL) is the most common complaint of pregnancy in females with a prevalence of 5%. Numerous documents have shown that single nucleotide polymorphisms are able to change miRNA transcription and/or maturation, which may alter the incidence of disorders such as RPL.

Objective: To assess the relationship of miR-146aC G (rs2910164) and miR-196a2T C (rs11614913) with RPL susceptibility in Iranian women.

Fertility preservation in women with ovarian cancer: Finding new pathways: A case-control study.

Background: Surgery and chemotherapy are the two most common treatments for cancers, including ovarian cancer. Although most ovarian cancers occur over the age of 45 yr, it may involve younger women and affect their reproductive ability.

Objective: To assess the expression of Leucine-rich repeat-containing G-protein coupled receptor 5 (), Forkhead Box O1 (), and genes in the ovarian cancer tissues as well as ovarian cancer cell lines.

Genomics and Transcriptomics: The Powerful Technologies in Precision Medicine.

In a clinical trial, people with the same disease can show different responses after treatment with the same drug and exactly under the same conditions. Some of them may improve, some may not show any response, and occasionally side effects may be observed. In other words, people with the same disease process under the same therapeutic conditions may have different responses.

Deficient Expression of in Human Testis is Related to Spermatogenesis Dysfunction, Especially in Meiosis I.

Introduction: () contributes to miRNA biogenesis, and defects in its expression could lead to defects in spermatogenesis.

Methods: Here, we assess gene and protein expression levels of in the testicular biopsy specimens obtained from men with obstructive azoospermia (OA, n = 19) and various types of non-obstructive azoospermia (NOA) including maturation arrest (MA, n = 17), Sertoli cell-only syndrome (SCOS, n = 20) and hypospermatogenesis (HYPO, 18). Also, samples of men with NOA were divided into two groups based on successful and unsuccessful sperm recovery, NOA+ in 21 patients and NOA- in 34 patients.

Major miRNA Involved in Insulin Secretion and Production in Beta-Cells.

Insulin is implicated as a leading factor in glucose homeostasis and an important theme in diabetes mellitus (DM). Numerous proteins are involved in insulin signaling pathway and their dysregulation contributes to DM. microRNAs (miRNAs) as single-strand molecules have a critical effect on gene expression at post-transcriptional levels.

Upregulation of the RNF8 gene can predict the presence of sperm in azoospermic individuals.

Objective: In this study, specimens from testicular biopsies of men with nonobstructive azoospermia (NOA) were used to investigate whether RNF8 gene could serve as a biomarker to predict the presence of sperm in these patients.

Methods: Testicular biopsy specimens from 47 patients were classified according to the presence of sperm (positive vs. negative groups) and investigated for the expression of RNF8.

Some of the Factors Involved in Male Infertility: A Prospective Review.

Infertility is defined as the inability of couples to have a baby after one year of regular unprotected intercourse, affecting 10 to 15% of couples. According to the latest WHO statistics, approximately 50-80 million people worldwide sufer from infertility, and male factors are responsible for approximately 20-30% of all infertility cases. The diagnosis of infertility in men is mainly based on semen analysis.

Testicular expression of TDRD1, TDRD5, TDRD9 and TDRD12 in azoospermia.

Background: Tudor domain-containing proteins (TDRDs) play a critical role in piRNA biogenesis and germ cell development. piRNAs, small regulatory RNAs, act by silencing of transposons during germline development and it has recently been shown in animal model studies that defects in TDRD genes can lead to sterility in males.

Methods: Here we evaluate gene and protein expression levels of four key TDRDs (TDRD1, TDRD5, TDRD9 and TDRD12) in testicular biopsy samples obtained from men with obstructive azoospermia (OA, n = 29), as controls, and various types of non-obstructive azoospermia containing hypospermatogenesis (HP, 28), maturation arrest (MA, n = 30), and Sertoli cell-only syndrome (SCOS, n = 32) as cases.
