Summary
Non-coding RNAs (ncRNAs) are key regulators of fat deposition in farm animals, influencing meat quality. Further research into these molecular mechanisms can improve livestock traits.
Area of Science:
- Animal Science
- Molecular Biology
- Genetics
Background:
- Fat deposition is vital for energy metabolism and meat quality in farm animals.
- It is a complex process regulated by numerous genes and molecular factors.
- Non-coding RNAs (ncRNAs) are increasingly recognized for their significant role in modulating fat deposition.
Purpose of the Study:
- To summarize the molecular mechanisms regulating fat deposition in farm animals.
- To review the roles of various ncRNAs (miRNAs, lncRNAs, circRNAs) in fat deposition.
- To identify future research directions in this field.
Main Methods:
- Literature review and synthesis of existing research.
- Focus on transcription factors, regulatory genes, and signaling pathways.
- Analysis of ncRNA functions in pigs, cattle, sheep, ducks, and chickens.
Main Results:
- ncRNAs critically regulate fat deposition processes in various farm animals.
- Specific ncRNAs like miRNAs, lncRNAs, and circRNAs are involved.
- Understanding these pathways offers potential for improving meat quality traits.
Conclusions:
- ncRNAs are pivotal in the molecular regulation of fat deposition.
- Targeting ncRNAs holds promise for enhancing meat quality in livestock.
- Further investigation is needed to fully elucidate these complex regulatory networks.

01:23Types of 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.

02:39lncRNA - Long Non-coding RNAs
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 (lncRNA)...

01:23Transcriptional Regulation: Riboswitches
Riboswitches are RNA elements that regulate gene expression by altering their secondary structures in response to specific effector molecules. These elements, located in the leader regions of certain mRNAs, act as transcriptional regulators by toggling between alternative conformations to control downstream gene expression. Riboswitch-mediated regulation is a precise mechanism for modulating biosynthetic pathways, as exemplified by the riboflavin biosynthesis pathway in Bacillus...
01:29Translational Regulation
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,...
