In the chilling science fiction movie Gattaca, Ethan Hawke stars as a man with "inferior genes" who assumes another's genetic identity to escape a dead-end future. The 1997 film illustrates the very real fear swirling around today's genome research "” fear that private genetic information could be used negatively against us. Last year, after a published paper found serious security holes in the way DNA data is made publicly available, health institutes in the United States and across...

A specific genetic region that has been increasingly identified as the strongest genetic link to psoriasis has an even more significant role in the chronic skin disease than has been suspected, University of Utah medical researchers show in a new study.In the Aug. 13 issue of PLoS Genetics, researchers in the U School of Medicine's Department of Dermatology confirm that the presence of HLA-Cw*0602, a gene variation or allele on chromosome 6 found to be associated with psoriasis by numerous...

St. Jude Children's Research Hospital scientists lead survey of genome that identifies new genes linked to cancer risk and treatment response Scientists at St. Jude Children's Research Hospital have identified inherited variations in two genes that account for 37 percent of childhood acute lymphoblastic leukemia (ALL), including a gene that may help predict drug response. The findings stem from the first complete search of the human genetic blueprint or genome to look for inherited risk...

Researchers at the Keck School of Medicine of the University of Southern California (USC) have identified a novel genetic mechanism that may govern an individual's risk of developing prostate cancer.The findings, published today in the Public Library of Science (PLoS) Genetics journal, found mechanisms involved in cancer-associated sites in areas where no genes are present (gene 'deserts') at a chromosomal region called 8q24. The new findings show that some of these sites have embedded...

At one time or another most of us wonder where we came from, where our parents or grandparents and their parents came from.  Did our ancestors come from Europe or Asia?  As curious as we are about our ancestors, for practical purposes, we need to think about the ancestry of our genes, according to Cecil Lewis, assistant professor of anthropology at the University of Oklahoma.  Lewis says our genetic ancestry influences the genetic traits that predispose us to risk or resistance...

Genetic research indicates that Australian Aborigines initially arrived via south Asia. Researchers writing in the open access journal BMC Evolutionary Biology have found telltale mutations in modern-day Indian populations that are exclusively shared by Aborigines.Dr Raghavendra Rao worked with a team of researchers from the Anthropological Survey of India to sequence 966 complete mitochondrial DNA genomes from Indian 'relic populations'. He said, "Mitochondrial DNA is inherited only from the...

REYKJAVIK, Iceland, July 13 /PRNewswire-FirstCall/ -- Scientists at deCODE genetics (Nasdaq: DCGN) and colleagues from Europe and the United States today report the discovery of a common single-letter variant in the sequence of the human genome (SNP) conferring increased risk of atrial fibrillation (AF) and stroke. The findings will be integrated directly into the deCODE AF(TM) reference laboratory test for gauging individual risk of AF and stroke and helping to identify stroke patients...

South Korean geneticists have recently finished sequencing the genome of a Korean male "” the fifth fully-sequenced human to date "” and have stumbled upon a number of genetic variations they say may lead to a predisposition to several forms of cancer, rheumatoid arthritis and a variety of other genetically influenced diseases. In a summary of their work, published this week in the scientific journal Nature, the scientists detailed how they exploited new technological advances in...

Mayo Clinic and University of California-San Francisco medical researchers say they have found a connection between DNA alterations and brain cancer. The scientists say they found a linkage between DNA variations on human chromosome 9 and aggressive brain cancer known as glioblastoma. The study, conducted with different patient populations at each institution, looked for genome-wide associations. The researchers said they found that people with the specific DNA alterations -- also known as...

REYKJAVIK, Iceland, July 6 /PRNewswire-FirstCall/ -- Scientists at deCODE genetics (Nasdaq: DCGN) and academic colleagues from Europe and the United States today present in the journal Nature Genetics the discovery of common genetic risk factors for basal cell carcinoma (BCC) that affect people with fair and dark complexions alike. deCODE had previously discovered five common single-letter variants in the sequence of the human genome (SNPs) linked to risk of BCC, the most common cancer in...

House Mouse, Mus musculus
2012-05-01 11:42:07

Even in the wild, this rodent is associated with humans by destroying crops and stored food. The house mouse is also known as the fancy mouse, a common pet. It is also a widely used laboratory animal, important for testing in genetics, biology, and medicine. There are three recognized subspecies of the house mouse. These mice thrive in a number of locations including fields, houses, and commercial structures. An adult male house mouse can have a body length of up to 3.9 in, and tail length...
