New gene may offer clues to infertility in both cows and women
A newly identified gene that controls embryo development in cows may someday offer clues into the cause of infertility in women. view more (2007-10-30)
The first men and women from the Canary Islands were Berbers
A team of Spanish and Portuguese researchers has carried out molecular genetic analysis of the Y chromosome (transmitted only by males) of the aboriginal population of the Canary Islands to determine their origin and the extent to which they have survived in the current population. view more (2009-10-22)
Finding of genetic region controlling cardiovascular sensitivity to anesthetic propofol
Researchers at The Medical College of Wisconsin in Milwaukee have identified the genetic region in rats responsible for cardiovascular collapse during anesthesia. view more (2009-09-11)
Columbia University Medical Center researchers discover potential mechanism for tumor growth
Researchers at Columbia University Medical Center have identified an inherent feature of stem and progenitor cells that may promote initiation and progression of cancerous tumors. view more (2005-12-16)
Two From One-Pitt Research Maps Out Evolution of Genders From Hermaphroditic Ancestors
Research from the University of Pittsburgh published in the Nov. 20 edition of "Heredity" could finally provide evidence of the first stages of the evolution of separate sexes, a theory that holds that males and females developed from hermaphroditic ancestors. view more (2008-11-21)
UCLA researchers examine human embryonic stem cell genome
Stem cell researchers from UCLA used a high resolution technique to examine the genome, or total DNA content, of a pair of human embryonic stem cell lines and found that while both lines could form neurons, the lines had differences in the numbers of certain genes that could control such things as individual traits and disease susceptibility. view more (2008-03-28)
New Understanding Of Role Of Breast Cancer Gene In Normal Function And Disease
Researchers at the Medical Research Council (MRC) Cancer Cell Unit, Cambridge have gained an important new insight into the role of the breast cancer gene known as BRCA2. It appears to have a key function in cell division which needs to happen accurately for normal cell reproduction and repair, otherwise disease occurs. The findings are published... view more...

New insight into the genetics of brain tumor formation
In a G&D paper published online ahead of its April 1 print publication date, Dr. William Kaelin (Dana Farber Cancer Institute) and colleagues identify a potential new neuronal tumor suppressor. view more (2008-03-18)
Study examines association between type of genetic characteristics and cancer
Persons with a certain type of homozygosity (having two identical copies of the same gene, one inherited from each parent), may have a greater predisposition to cancer, according to a study in the March 26 issue of JAMA. view more (2008-03-26)
Finnish families guide to gene behind abnormal lipid levels and atherosclerosis
Coronary heart disease is the leading cause of death in Western societies. Unfavorable serum lipid levels, high cholesterol, high triglycerides and low high-density lipoprotein (HDL) cholesterol, are well-known risk factors for atherosclerosis and coronary heart disease. Familial combined hyperlipidemia (FCHL), characterized by these changes in... view more... (2004-03-01)
Unravelling the North West's Viking past
The blood of the Vikings is still coursing through the veins of men living in the North West of England - according to a new study which has been just published. view more (2008-02-11)
Molecular Biologists Reveal Historical Secrets
By analysing DNA from ancient human remains researchers can determine the sex and ethnicity of our ancestors and help historians to compose a complete picture of their life and customs. In the region of Altai Mountains archaeologists discovered remains of an ancient civilisation. During excavations, they found many bones of newborns and wondered... view more... (2002-07-05)
Mouse model provides a new tool for investigators of human developmental disorder
Wolf-Hirschhorn Syndrome (WHS) is a human disease caused by spontaneous genetic deletions. Children born with WHS have a characteristic set of facial features, including a wide flat nose bridge, downturned mouth, high forehead, and highly arched eyebrows. view more (2009-04-21)
Large multicenter study suggests new genetic markers for Crohn's disease
What is believed to be the largest study of its kind for the genetic roots of inflammatory bowel diseases has suggested new links to Crohn's Disease as well as further evidence that some people of Jewish descent are more likely to develop it. view more (2008-03-27)
New clues for treatment of liver cancer
By generating tumors in laboratory mice that mimic human liver cancer and by comparing the DNA of mouse and human tumors, researchers at Cold Spring Harbor Laboratory have identified two genes that are likely to play a role in the third leading cause of human cancer deaths. view more (2006-06-29)
Identified main genetic variants involved in response to HIV
This international collaboration has been the largest ever to have taken place in a large scale study on genetic differences between patients infected by HIV, and is the first study of this kind in the field of infectious disease. view more (2007-07-23)
Tug-of-cell war
Researchers at the School of Life Sciences, University of Dundee have made an exciting new discovery on how cells regulate themselves and prevent cancer as reported in Nature tomorrow (Wednesday). Dr Tomo Tanaka and his team members, Drs Hilary Dewar and Kozo Tanaka have uncovered a tug of war that cells use to collect their full complement of... view more... (2004-02-10)
Rare mutation causes early heart disease and metabolic syndrome
Yale School of Medicine researchers have identified a rare defect in a single gene that poses a substantial risk for metabolic syndrome and early heart disease, the leading cause of death worldwide. view more (2007-03-02)
Chromosomes tell tale of patient's risk for new, future cancer
Hodgkin's disease survivors who have greater genetic instability in their white blood cells are two-and-a-half times more likely to develop another type of cancer. view more (2007-04-17)
Cell survival depends on chromosome integrity
As part of a large National Institutes of Health-funded Technology Centers for Networks and Pathways project, Johns Hopkins researchers have discovered protein machinery important for cells to keep chromosomes intact. view more (2006-07-10)
