Summary of "Long non-coding RNAs and pyroptosis."

Long noncoding RNAs (lncRNAs) are defined as transcripts longer than 200 nucleotides that have no or only a low coding potential. They are involved in the progression of multiple diseases by the regulation of mechanisms related to epigenetic modifications and transcriptional and posttranscriptional processing. Recent studies have revealed an important function of lncRNAs in the regulation of pyroptosis, a type of programmed cell death associated with inflammatory responses that plays a critical role in many diseases. Through direct or indirect action on proteins related to the pyroptosis signaling pathway, lncRNAs are involved in the pathological processes related to cardiovascular diseases, kidney diseases, immune diseases and other diseases. Based on the expression characteristics of lncRNAs, this paper reviews the role of lncRNAs in regulating pyroptosis, aiming to provide new ideas for the research of lncRNAs regulating pyroptosis and treating pyroptosis-related diseases.

Medical and Biotech [MESH] Definitions

Small double-stranded, non-protein coding RNAs, 21-25 nucleotides in length generated from single-stranded microRNA gene transcripts by the same RIBONUCLEASE III, Dicer, that produces small interfering RNAs (RNA, SMALL INTERFERING). They become part of the RNA-INDUCED SILENCING COMPLEX and repress the translation (TRANSLATION, GENETIC) of target RNA by binding to homologous 3'UTR region as an imperfect match. The small temporal RNAs (stRNAs), let-7 and lin-4, from C. elegans, are the first 2 miRNAs discovered, and are from a class of miRNAs involved in developmental timing.

Small double-stranded, non-protein coding RNAs (21-31 nucleotides) involved in GENE SILENCING functions, especially RNA INTERFERENCE (RNAi). Endogenously, siRNAs are generated from dsRNAs (RNA, DOUBLE-STRANDED) by the same ribonuclease, Dicer, that generates miRNAs (MICRORNAS). The perfect match of the siRNAs' antisense strand to their target RNAs mediates RNAi by siRNA-guided RNA cleavage. siRNAs fall into different classes including trans-acting siRNA (tasiRNA), repeat-associated RNA (rasiRNA), small-scan RNA (scnRNA), and Piwi protein-interacting RNA (piRNA) and have different specific gene silencing functions.

A set of three nucleotides in a protein coding sequence that specifies individual amino acids or a termination signal (CODON, TERMINATOR). Most codons are universal, but some organisms do not produce the transfer RNAs (RNA, TRANSFER) complementary to all codons. These codons are referred to as unassigned codons (CODONS, NONSENSE).

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

Type of programmed cell death associated with infection by intracellular pathogens. It is characterized by INFLAMMASOME formation; activation of CASPASE 1; and CYTOKINES mediated inflammation.
