Summary
This study reveals the fecal proteome of healthy Sarda sheep, identifying 1046 proteins, including those crucial for immune response and proteolysis. These findings offer new insights into sheep gut health and potential future research directions.
Area of Science:
- Animal Science
- Proteomics
- Microbiome Research
Background:
- The sheep fecal microbiota has been characterized using multi-omics.
- Understanding the host fecal proteome is essential for assessing gut health.
Purpose of the Study:
- To characterize the fecal proteome of healthy Sarda sheep.
- To identify proteins involved in immune response and proteolysis in sheep feces.
Main Methods:
- Reanalysis of mass spectra from a previous multi-omics study.
- Utilized a host-specific database for protein identification.
- Liquid Chromatography/high-resolution Mass Spectrometry (LC/HR-MS).
Main Results:
- Identified 5349 non-redundant tryptic peptide sequences, corresponding to 1046 unique proteins.
- The core fecal proteome consisted of 431 proteins, primarily related to immune response and proteolysis.
- Detailed investigation of proteins involved in immune/inflammatory responses and peptidases.
Conclusions:
- Provides novel insights into the protein repertoire in the sheep intestinal lumen.
- Establishes a foundation for future proteomics studies on sheep gut health.
- Facilitates monitoring of fecal proteome changes related to production, health, and microbiota variations.

Cloning of Dolly the Sheep
7.8K
The first successfully cloned mammal was Dolly, a sheep, born on 5th July 1996 at Roslin Institute, Scotland. The cloned sheep was named after the American singer Dolly Parton. Dolly lived for seven years and died of respiratory complications, which is speculated to be due to the actual age of her DNA. Because the DNA in cloned cells belongs to an older individual, the cloned individual’s life expectancy may be affected. Indeed, analysis of Dolly’s DNA revealed shorter...

Proteomics
9.9K
A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term...

Reproductive Cloning
32.8K
Reproductive cloning is the process of producing a genetically identical copy—a clone—of an entire organism. While clones can be produced by splitting an early embryo—similar to what happens naturally with identical twins—cloning of adult animals is usually done by a process called somatic cell nuclear transfer (SCNT).
Somatic Cell Nuclear Transfer
In SCNT, an egg cell is taken from an animal and its nucleus is removed, creating an enucleated egg. Then a somatic...

Imprinting
11.2K
Behavioral imprinting is observed in some newborn animals and occurs when they develop strong and specific attachments to another animal (usually a parent) following brief, early-life exposures. Offspring imprint onto parents within a brief period after birth or hatching; this time window is called the critical period. Once imprinting occurs, the bond established between the parents and their offspring is usually long-lasting.

Lysogenic Cycle of Bacteriophages
68.1K
In contrast to the lytic cycle, phages infecting bacteria via the lysogenic cycle do not immediately kill their host cell. Instead, they combine their genome with the host genome, allowing the bacteria to replicate the phage DNA along with the bacterial genome. The incorporated copy of the phage genome is called the prophage. Some prophages can re-activate and enter the lytic cycle. This often occurs in response to a perturbation, such as DNA damage, but can also transpire in the absence of...
