High throughput sequencing reveals long non-coding RNAs (lncRNAs) are crucial in cellular machinery. This review details known insect lncRNAs and bioinformatic methods for hexapod genome annotation.
Area of Science:
- Genomics
- Molecular Biology
- Bioinformatics
Background:
- High throughput sequencing (HTS) advanced transcriptome complexity assessment.
- Long non-coding RNAs (lncRNAs) are vital regulatory molecules across life.
- lncRNA characterization is limited in many non-model organisms, especially insects.
Purpose of the Study:
- To review experimentally validated long non-coding RNAs in insects.
- To survey bioinformatic approaches for lncRNA annotation in hexapods.
- To highlight the importance of lncRNAs in diverse biological processes.
Main Methods:
- Literature review of experimentally validated insect lncRNAs.
- Analysis of bioinformatic tools and strategies for lncRNA discovery.
- Comparative genomics approaches for lncRNA identification.
Main Results:
- A growing repertoire of functionally important insect lncRNAs has been identified.
- Various computational methods exist for lncRNA prediction and annotation.
- lncRNAs play roles in essential biological processes like gene regulation.
Conclusions:
- lncRNAs are fundamental components of cellular machinery in insects.
- Further research and improved bioinformatic tools are needed for comprehensive insect lncRNA annotation.
- Understanding insect lncRNAs can provide insights into broader biological mechanisms.

Experimental RNAi
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...
siRNA - Small Interfering RNAs
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...
