LncRNA-miRNA-mRNA regulatory axes as potential biomarkers in cervical cancer: a comprehensive overview.

Despite the recent advances in vaccination and treatment strategies, cervical cancer continues to claim numerous lives every year. Owing to the fact that non-coding RNAs (ncRNAs) such as long non-coding RNAs (lncRNAs) and microRNAs (miRNAs) interact with coding transcripts, and effectuate key roles in the tumorigenesis and metastasis of cervical cancer, there has been extensive research in recent years to explore their potential as biomarkers for early detection, or as therapeutic targets. Through this review, we aim to provide a comprehensive overview of the recent advancements in discoveries about cervical cancer-associated lncRNA-miRNA-mRNA axes, their dysregulation, and their roles in various signaling pathways associated with the growth, survival, invasion, and metastasis of cervical cancer cells.

Increased platelet numbers have long been associated with cancer patients' tumor metastasis and poor clinical prognosis.

Ovarian cancer (OC) is one of the most common and fatal types of gynecological cancer. OC is usually detected at the advanced stages of the disease, making it highly lethal. miRNAs are single-stranded, small non-coding RNAs with an approximate size ranging around 22 nt.

Landscape of Clinically Relevant Exosomal tRNA-Derived Non-coding RNAs.

Exosomes are extra-cellular vesicles that are < 150 nm that is formed by invagination of the plasma membrane and are released as vesicles. These contain proteins, RNA, and DNA as their cargo. In recent times, the non-coding RNA (ncRNA) present within exosomes has been studied extensively in the context of sorting, localization, and their potential as biomarkers.

Current Update on Nanotechnology-Based Approaches in Ovarian Cancer Therapy.

Ovarian cancer is one of the leading causes of cancer-related deaths among women.

Nanotechnology is one of the upcoming domains of science that is rechanneled towards targeted cancer therapy and diagnosis.

LncRNA-miRNA-mRNA regulatory axes in endometrial cancer: a comprehensive overview.

Introduction: Recent research on tumorigenesis and progression has opened up an array of novel molecular mechanisms in the form of interactions between cellular non-coding RNAs (long non-coding RNA[lncRNA]/microRNA [miRNA]) and coding transcripts that regulate health and disease. Endometrial cancer (EC) is a prominent gynecological malignancy with a high incidence rate and poorly known etiology and prognostic factors that hinder the success of disease management. The emerging role of lncRNA-miRNA-mRNA interactions and their dysregulation in the pathophysiology of EC has been elucidated in many recent studies.

Comparative expression analysis of tRF-3001a and tRF-1003 with corresponding miRNAs (miR-1260a and miR-4521) and their network analysis with breast cancer biomarkers.

Background: MicroRNAs and tRFs (tRNA-derived fragments) are small non-coding RNAs that are promising breast cancer (BC) biomarkers. miRNA sequences are found within tRFs. For example, miR-1260a and miR-4521 sequences are found within tRF-3001a and tRF-1003, respectively.

Breast cancer fibroblasts and cross-talk.

The breast tumor microenvironment is one of the crucial elements supporting breast cancer tumor progression and metastasis. The fibroblasts are the chief cellular component of the stromal microenvironment and are pathologically activated and differentiated into breast cancer-associated fibroblasts (CAFs). The catabolic phenotype of breast CAFs arises due to metabolic reprogramming of these fibroblasts under pseudo-hypoxic conditions.

A synergy of estradiol with leptin modulates the long non-coding RNA NEAT1/ mmu-miR-204-5p/IGF1 axis in the uterus of high-fat-diet-induced obese ovariectomized mice.

Obesity increases the risk of developing cancers for both males and females. This study investigated potential crosstalk between estradiol and leptin signaling pathways within the endometrium of high-fat-diet-induced obese ovariectomized mice to gain insight into possible links between obesity and endometrial cancer. We administered 17-β estradiol (0.

Long Non-coding RNA NEAT1 as an Emerging Biomarker in Breast and Gynecologic Cancers: a Systematic Overview.

Long non-coding RNAs (lncRNAs) are emerging regulators of cellular pathways, especially in cancer development. Among the lncRNAs, nuclear paraspeckle assembly transcript 1 (NEAT1) forms a scaffold for a nuclear body; the paraspeckle and aberrant expression of NEAT1 have been reported in breast and gynecologic cancers (ovarian, cervical, endometrial, and vulvar). Abundantly expressed NEAT1 in breast and gynecologic cancers generally contribute to tumor development by sponging its corresponding tumor-suppressive microRNAs or interacting with various regulatory proteins.

Small nucleolar RNA and its potential role in breast cancer - A comprehensive review.

Small Nucleolar RNAs (snoRNAs) are known for their canonical functions, including ribosome biogenesis and RNA modification. snoRNAs act as endogenous sponges that regulate miRNA expression. Thus, precise snoRNA expression is critical for fine-tuning miRNA expression.

Regulation of processing bodies: From viruses to cancer epigenetic machinery.

Processing bodies (PBs) are 100-300 nm cytoplasmic messenger ribonucleoprotein particle (mRNP) granules that regulate eukaryotic gene expression. These cytoplasmic compartments harbor messenger RNAs (mRNAs) and several proteins involved in mRNA decay, microRNA silencing, nonsense-mediated mRNA decay, and splicing. Though membrane-less, PB structures are maintained by RNA-protein and protein-protein interactions.

Liquid biopsy in ovarian cancer.

Ovarian cancer is typically diagnosed at an advanced stage and poses a significant challenge to treatment and recovery. Relapsed ovarian cancer and chemoresistance of ovarian tumor cells are other clinical challenges. Liquid biopsy is an essential non-invasive diagnostic test that evaluates circulating tumor cells and tumor DNA, as well as other blood markers that may be useful in guiding precision medicine.

Gene expression changes and promoter methylation with the combined effects of estradiol and leptin in uterine tissue of the ovariectomized mice model of menopause.

Substantial epidemiological studies have shown an association of obesity with the common gynecological malignancy, endometrial cancer. The relevant interactions and contribution of estradiol and the adipose cytokine, leptin, in endometrial lesions are not completely understood. Suitable animal models to understand the physiological response of uterine tissue to the combined effects of estradiol-leptin are lacking.

Regulated expression of Gemin5, Xrn1, Cpeb and Stau1 in the uterus and ovaries after superovulation and the effect of exogenous estradiol and leptin in rodents.

The aim of this study was to evaluate whether Gemin 5, Cpeb, Xrn1, and Stau1 expression in rodent ovaries and uterine tissues is dependent on gonadotropins, steroid hormones, and leptin in the superovulation and ovariectomized mouse models of menopause. Treatment of pregnant mare serum gonadotropin-primed rats with human chorionic gonadotropin (hCG) significantly induced Stau1 and Gemin 5 messenger RNA expression in rat ovaries. Gemin 5 expression in ovaries was sustained at relatively high levels at 12 h and 24 h post hCG treatment compared to Stau1, suggesting its role in follicle development, ovulation, and luteogenesis in rat ovaries.
