Genetic Mosaic Of DNA Revealed
2012-11-19 05:42:39

redOrbit Staff & Wire Reports - Your Universe Online A new study of stem cells derived from skin tissue has challenged the commonly held notion that a person's cells all share the same DNA sequence, arguing instead that genetic variation may occur to a greater extent than experts had previously believed. Researchers at the Yale School of Medicine set out to challenge the theory that human cells are comprised of identical genetic material, and that a body's functions are governed by...

Believed to 'ingest' DNA from other simple organisms Up to ten per cent of the active genes of an organism that has survived 80 million years without sex are foreign, a new study from the University of Cambridge and Imperial College London reveals. The asexual organism, the bdelloid rotifer, has acquired a tenth of its active genes from bacteria and other simple organisms like fungi and algae. The findings were reported today in the journal PLoS Genetics. Bdelloid rotifers are best...

Stickleback's Aggressive Behavior Studied
2012-11-15 18:15:46

University of Illinois at Urbana-Champaign With a mate and a nest to protect, the male threespined stickleback is a fierce fish, chasing and biting other males until they go away. Now researchers are mapping the genetic underpinnings of the stickleback's aggressive behavior. Armed with tools that allow them to see which genes are activated or deactivated in response to social encounters, a team from the University of Illinois has identified broad patterns of gene activity that...

Researchers Discover Key Gene That Makes Humans Distinct From Apes
2012-11-15 13:16:05

April Flowers for redOrbit.com - Your Universe Online An international team of researchers, led by the University of Edinburgh, has discovered a new gene that helps to solve one of life's greatest mysteries — what makes us human? The gene — miR-941 — helps to explain how humans evolved from apes. It appears to have played a crucial role in the development of the human brain and may shed light on our use of tools and language. This is the first time, according...

Pig Genome Sequenced: Offers Significant Implications Abroad
2012-11-14 15:57:11

Brett Smith for redOrbit.com - Your Universe Online A massive team of international researchers has announced the successful sequencing of the first female domestic pig´s genome. There have already been many similarities established between pigs and humans and the new genomic analysis reveals some new twists and a few distinctions to that relationship, according to reports on the work published in the journals Nature and Proceedings of the National Academy of Sciences (PNAS)....

Findings will help our genetic understanding of dangerous new viruses Scientists studying the genes and proteins of human cells infected with a common cold virus have identified a new gene identification technique that could increase the genetic information we hold on animals by around 70 to 80 per cent. The findings, published in Nature Methods, could revolutionize our understanding of animal genetics and disease, and improve our knowledge of dangerous viruses such as SARS that jump the...

Research presented at American Society of Human Genetics annual meeting, Nov. 6 to 10, San Francisco About 10.6% of the inherited genetic risk for developing coronary artery disease (CAD) can be explained by specific DNA variations, according to research reported today at the American Society of Human Genetics 2012 meeting. The research, conducted by scientists in the CARDIoGRAMplusC4D consortium, pinpointed 20 previously unidentified mutations during a two-stage meta-analysis of 63,746...

Humans And Primates Share DNA But Genes Work Differently
2012-11-08 08:43:59

April Flowers for redOrbit.com - Your Universe Online Our primate cousins share over 90% of our DNA, but the expression or activity patterns of genes differ across species in ways that explain the distinct biology and behavior of each species. In a presentation at the American Society of Human Genetics 2012 meeting, University of Chicago associate professor of human genetics Yoav Gilad, Ph.D. described the DNA factors that contribute to the differences. Up to 40 percent of the...

Johns Hopkins researchers have succeeded in teaching computers how to identify commonalities in DNA sequences known to regulate gene activity, and to then use those commonalities to predict other regulatory regions throughout the genome. The tool is expected to help scientists better understand disease risk and cell development. The work was reported in two recent papers in Genome Research, published online on July 3 and Sept. 27. “Our goal is to understand how regulatory...

Unlocking DNA Repair Secrets
2012-10-31 12:53:16

University of Sheffield Scientists from the University of Sheffield have unlocked one of the secrets to DNA repair —helping doctors identify DNA base damage and a patient's susceptibility to certain types of cancer. Groundbreaking research led by Dr David Williams from the University of Sheffield's Department of Chemistry and an international collaboration of expert researchers has discovered how some proteins recognize damaged bases within DNA which, if untreated, could lead to...

Knockout Mouse
2013-10-02 11:52:01

A Knockout Mouse is a genetically engineered mouse in which researchers have inactivated, or “knocked out,” an existing gene by replacing it or disrupting it with an artificial piece of DNA. The loss of gene activity frequently causes changes in a mouse’s phenotype, which includes appearance, behavior, or other apparent and biochemical characteristics. Knockout mice are significant animal models for studying the role of genes which have been sequenced but whose functions haven’t...
