Abstract:
Circular RNAs (circRNAs) are a novel type of endogenous non-coding RNA that have gained attention from researchers for their involvement in multiple biological processes. circRNAs are ubiquitously expressed in eukaryotic cells and regulate gene expression at the transcriptional or post-transcriptional level by interacting with microRNAs (miRNAs) or other molecules. The present review provides an overview of circRNAs, as well as insights into their roles in the development and progression of gastrointestinal cancer. Furthermore, combined with reported data, the present review investigates the potential of circRNAs to become diagnostic or predictive biomarkers of gastrointestinal cancer and may provide novel insights into the treatment of associated cancer types.

Anatomy of the Gastrointestinal System
Here's a detailed walkthrough of this complex system:

Gastrointestinal Motility Disorders
Histology of the Gastrointestinal (GI) Tract
The mucosa is sometimes called a mucous membrane due to its mucus-secreting features. This membrane is composed of epithelium, which directly interacts with ingested substances, and the lamina propria, a layer...
RNA Interference
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
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...
