Summary
Non-coding RNAs, including microRNAs (miRNAs) and long non-coding RNAs (lncRNAs), play a crucial role in cold adaptation. This review explores their functions in mammalian hibernation and insect cold hardiness.
Area of Science:
- Molecular Biology
- Genetics
- Ecology
Background:
- Organisms exhibit significant physiological and biochemical adaptations to survive winter conditions.
- Small mammals and insects serve as key models for studying cold adaptation.
- While molecular mechanisms are increasingly understood, the role of non-coding RNAs in cold adaptation requires further elucidation.
Purpose of the Study:
- To review molecular changes associated with cold adaptation in mammals and insects.
- To describe the biogenesis and function of microRNAs (miRNAs) and long non-coding RNAs (lncRNAs).
- To highlight the significance of differentially expressed non-coding RNAs in cold adaptation.
Main Methods:
- Literature review of existing research on cold adaptation.
- Analysis of molecular changes, including non-coding RNA pathways.
- Case studies focusing on mammalian hibernation and insect cold hardiness.
Main Results:
- Non-coding RNAs, such as miRNAs and lncRNAs, are implicated in cold adaptation processes.
- Specific examples of differentially expressed non-coding RNAs in cold-adapted species are identified.
- The regulatory roles of these non-coding RNAs in response to low temperatures are discussed.
Conclusions:
- Non-coding RNAs are vital components of the molecular machinery enabling organisms to adapt to cold.
- Further research into miRNA and lncRNA functions can enhance our understanding of cold tolerance.
- This knowledge has implications for fields ranging from evolutionary biology to biotechnology.

Translational Regulation
739
Translational regulation in prokaryotes ensures efficient protein synthesis by controlling ribosome access to mRNA. This regulation is mediated by secondary RNA structures, including translational riboswitches, RNA thermometers, and small RNAs (sRNAs), which respond to intracellular and environmental signals to modulate gene expression.Translational RiboswitchesRiboswitches in the leader region of mRNAs can regulate translation by altering the accessibility of the Shine-Dalgarno (SD) sequence,...

lncRNA - Long Non-coding RNAs
10.1K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

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.

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.
