Summary of "Circular RNAs: pivotal molecular regulators and novel diagnostic and prognostic biomarkers in non-small cell lung cancer."

Circular RNAs (circRNAs), a large class of non-coding RNAs with covalently closed-loop structures, are abundant, stable, conserved, and have tissue and developmental-stage specificities. The biological functions of circRNAs are varied. Moreover, circRNAs participate in various pathological processes, especially in multiple cancers. Lung cancer is the most frequent malignant tumor worldwide. Many studies have suggested that circRNAs are pivotal in non-small cell lung cancer. This article aims to provide a retrospective review of the latest research on the functions of circRNAs in non-small cell lung cancer. In particular, we focus our discussion on the role of circRNAs in cell-cycle regulation and the epithelial-mesenchymal transition, and also discuss the known regulatory molecular mechanisms of circRNAs in non-small cell lung cancer.

Medical and Biotech [MESH] Definitions

Double-stranded DNA of MITOCHONDRIA. In eukaryotes, the mitochondrial GENOME is circular and codes for ribosomal RNAs, transfer RNAs, and about 10 proteins.

RNA molecules which hybridize to complementary sequences in either RNA or DNA altering the function of the latter. Endogenous antisense RNAs function as regulators of gene expression by a variety of mechanisms. Synthetic antisense RNAs are used to effect the functioning of specific genes for investigative or therapeutic purposes.

The field of medicine concerned with understanding the biochemical basis of health and disease and involved in developing diagnostic and therapeutic methods that utilize MOLECULAR BIOLOGY techniques.

A type of junction that attaches one cell to its neighbor. One of a number of differentiated regions which occur, for example, where the cytoplasmic membranes of adjacent epithelial cells are closely apposed. It consists of a circular region of each membrane together with associated intracellular microfilaments and an intercellular material which may include, for example, mucopolysaccharides. (From Glick, Glossary of Biochemistry and Molecular Biology, 1990; Singleton & Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed)

The removal of a circular disk of the cranium. It is performed with a trephine, a small circular saw with a center pin mounted on a hollow metal shaft to which is attached a transverse handle. (Random House Unabridged Dictionary, 2d ed)
