Summary
Circular RNAs (circRNAs) show altered expression in endometriosis, potentially impacting disease development. These findings highlight circRNAs as key players in endometriosis pathogenesis.
Area of Science:
- Molecular Biology
- Genetics
- Reproductive Biology
Background:
- Circular RNAs (circRNAs) with miRNA response elements (MREs) act as competing RNA (ceRNA) regulators of gene expression.
- Understanding circRNA roles is crucial for endometriosis research.
Purpose of the Study:
- To identify the expression profile of circRNAs in endometriosis.
- To investigate the potential role of circRNAs in endometriosis pathogenesis.
Main Methods:
- Microarray analysis of ovarian endometriomas and eutopic endometrium.
- Quantitative real-time RT-PCR validation in 24 patient samples.
- Bioinformatic prediction of MREs, ceRNA networks, and KEGG pathways.
Main Results:
- Identified 262 upregulated and 291 downregulated circRNAs in endometriosis.
- Predicted 1225 MREs, a ceRNA network of 122 miRNAs and 137 mRNAs.
- Associated these networks with nine biological pathways.
Conclusions:
- CircRNAs are differentially expressed in endometriosis.
- These dysregulated circRNAs may contribute to the pathogenesis of endometriosis.

Deformation in a Circular Shaft
948
One of the distinctive characteristics of circular shafts is their ability to maintain their cross-sectional integrity under torsion. In other words, each cross-section continues to exist as a flat, unaltered entity, simply rotating like a solid, rigid slab. To understand the distribution of shearing stress within such a shaft, consider a cylindrical section inside this circular shaft. This section has a length of L and a radius of R, with one end fixed. The radius of the cylindrical section is...

What is Gene Expression?
197.2K
Overview
Gene expression is the process in which DNA directs the synthesis of functional products, that is, proteins. Cells can regulate gene expression at various stages. It allows organisms to generate different cell types and enables cells to adapt to internal and external factors.
Genetic Information Flows from DNA to RNA to Protein
A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is made up of nucleotides and proteins consist of amino...

RNA Interference
28.2K
RNA interference (RNAi) is a process in which a small non-coding RNA molecule blocks the post-transcriptional expression of a gene by binding to its messenger RNA (mRNA) and preventing the protein from being translated.
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...

RNA Structure
79.3K
Overview
The basic structure of RNA consists of a five-carbon sugar and one of four nitrogenous bases. Although most RNA is single-stranded, it can form complex secondary and tertiary structures. Such structures play essential roles in the regulation of transcription and translation.
Different Types of RNA Have the Same Basic Structure
There are three main types of ribonucleic acid (RNA): messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). All three RNA types consist of a...

Stress Concentrations in Circular Shafts
587
Consider the elastic torsion formula, which applies to a circular shaft with a consistent cross-section. This formula assumes that the shaft's ends are loaded with rigid plates firmly attached. However, in many cases, torques are applied to the shaft through mechanisms like flange couplings or gears, which are connected by keys inserted into keyways. This application method modifies the stress distribution near the point of torque application, causing it to deviate from the distributions...

Uniform Circular Motion
22.4K
Uniform circular motion is a specific type of motion in which an object travels in a circle with a constant speed. For example, any point on a propeller spinning at a constant rate is undergoing uniform circular motion. The second, minute, and hour hands of a watch also undergo uniform circular motion. It is hard to believe that points on these rotating objects are actually accelerating, even though the rotation rate is constant. To understand this, we must analyze the motion in terms of...
