Researchers sequence swine genome, discover associations that may advance animal and human health
Date:11/15/2012

MANHATTAN, Kan. -- An international scientific collaboration that includes two Kansas State University researchers is bringing home the bacon when it comes to potential animal and human health advancements, thanks to successfully mapping the genome of the domestic pig.

The sequenced genome gives researchers a genetic blueprint of the pig. It includes a complete list of DNA and genes that give pigs their traits like height and color. Once all of the genetic information is understood, scientists anticipate improvements to the animal's health as well as human health, as pigs and humans share similar physiologies.

"With the sequenced genome we have a better blueprint than we had before about the pig's genetics and how those genetic mechanisms work together to create, such as the unique merits in disease resistance," said Yongming Sang, research assistant professor of anatomy and physiology at Kansas State University.

For three years, Sang worked on the genome sequencing project with Frank Blecha, associate dean for the College of Veterinary Medicine and university distinguished professor of anatomy and physiology.

A report of the international study appears as the cover story for the Nov. 15 issue of the journal Nature.

The sequencing effort was led by the Swine Genome Sequencing Consortium. Researchers with the consortium invited Sang and Blecha to work on the project because of their expertise and published studies on the antimicrobial peptides and interferons that pigs use to genetically defend themselves against disease.

Sang and Blecha focused on these two families of immune genes, looking for gene duplications and gene-family expansions throughout the pig's 21,640 protein-coding genes, in an effort to help scientists with future pig-related research.

Sang also completed much of the genome annotation for Kansas State University's contributions. Genome annotation involves identifying, categor
