Summary
Small RNAs, including microRNAs (miRNAs), piRNAs, and siRNAs, are key gene regulators in parasitic nematodes. Their conserved functions and potential roles in host-parasite interactions are increasingly understood through genomic and sequencing data.
Area of Science:
- Molecular Biology
- Genetics
- Parasitology
Background:
- Small RNAs are crucial regulators of gene expression, with conserved silencing pathways across organisms.
- Genome data availability facilitates bioinformatic identification of small RNAs in parasitic nematodes.
Purpose of the Study:
- To review the known functions of three main small RNA classes (miRNAs, piRNAs, siRNAs) in parasitic nematodes.
- To explore their roles in parasite development and host-parasite interactions.
Main Methods:
- Bioinformatic identification of small RNA sequences using genomic data.
- Small RNA sequencing and microarray analysis to determine expression patterns.
- Review of existing literature on small RNA functions and applications.
Main Results:
- Temporal expression of nematode miRNAs suggests roles in modulating gene expression during parasite development.
- miRNAs are found in extracellular vesicles and host plasma, indicating potential host gene regulation.
- piRNAs and siRNAs are involved in gene silencing, including transposon suppression.
Conclusions:
- Small RNA pathways are conserved and functionally significant in parasitic nematodes.
- Understanding these pathways offers potential for novel control strategies at the host-parasite interface.

02:30siRNA - Small Interfering RNAs
18.2K
Small interfering RNAs, or siRNAs, are short regulatory RNA molecules that can silence genes post-transcriptionally, as well as the transcriptional level in some cases. siRNAs are important for protecting cells against viral infections and silencing transposable genetic elements.
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the...

02:53Ribosomal RNA Synthesis
14.5K
Ribosome synthesis is a highly complex and coordinated process involving more than 200 assembly factors. The synthesis and processing of ribosomal components occurs not only in the nucleolus but also in the nucleoplasm and the cytoplasm of eukaryotic cells.
Ribosome biogenesis begins with the synthesis of 5S and 45S pre-rRNAs by distinct RNA polymerases. The primary transcripts are extensively processed and modified before they are bound and folded by ribosomal proteins and assembly factors,...

Overview
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.

03:18Non-LTR Retrotransposons
13.0K
As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...

02:57piRNA - Piwi-interacting RNAs
7.4K
PIWI-interacting RNAs, or piRNAs, are the most abundant short non-coding RNAs. More than 20,000 genes have been found in humans that code for piRNAs while only 2000 genes have been found for miRNAs. piRNAs can act at the transcriptional and post-transcriptional levels and have a vital role in silencing transposable elements present in germ cells. They are also involved in epigenetic silencing and activation. Previously, they were thought to function only in germ cells but new evidence suggests...
