The genes are composed of DNA and are carried on the chromosomes. Genes direct the production of all the molecules that form the structures that of a cell. Genes determine the inherited characteristics that distinguish one individual from another. Each human has an estimated 90,000 genes.
A promising new chemotherapy target for a deadly form of leukemia has been discovered by researchers at the Stanford University Medical Center, US. – Cancer researchers at the Stanford University School of Medicine have discovered a promising new chemotherapy target for a deadly form of leukemia. Their discovery hinges on a novel “double agent” role for a molecular signal that regulates cell growth.
Genetic variation can be used to predict an individual’s pair-bonding behavior; Gene associated with pair-bonding in animals has similar effects in human males. – Variation in the gene for one of the receptors for the hormone vasopressin appears to be associated with how human males bond with their partners, according to an international team of researchers.
Contraceptive pills may cause change in women’s natural ability to choose a right partner, result in difficulties when trying to conceive, an increased risk of miscarriage and long intervals between pregnancies. – The contraceptive pill may disrupt women’s natural ability to choose a partner genetically dissimilar to themselves, research at the Universities of Liverpool and Newcastle has found.
About one-third of colorectal cancers are inherited, but the genetic cause of most of these cancers is unknown. The genes linked to colorectal cancer account for less than 5 percent of all cases. – Scientists at Northwestern University’s Feinberg School of Medicine and colleagues have discovered a genetic trait that is present in 10 to 20 percent of patients with colorectal cancer. The findings strongly suggest that the trait is a major contributor to colorectal cancer risk and likely the most common cause of colorectal cancer to date.
Biotechnology Industry Organization (BIO) welcomes advances in stem cell research, and stresses continued importance of pursuing all promising areas of research. – Biotechnology Industry Organization (BIO) President and CEO Jim Greenwood issued the following statement regarding the news that researchers at the Harvard Stem Cell Institute created 20 disease-specific stem cell lines thru the new induced pluripotent stem cell (iPS) technique:
If your first cigarette gave you a buzz and you now smoke, a gene may be to blame; Link between initial smoking pleasure, lifetime smoking habits and variation in nicotine receptor gene found by U-M-led team. – Anyone who has ever tried smoking probably remembers that first cigarette vividly. For some, it brought a wave of nausea or a nasty coughing fit. For others, those first puffs also came with a rush of pleasure or “buzz.”
Schizophrenia may be partly caused by the effects of unusual structural changes in genes. – People with schizophrenia (mental illness variously affecting behavior, thinking, and emotion) have an increased number of unusual chromosomal changes, particularly structural changes that have the potential to alter the function of the genes.
This study provides evidence on the relationship between maternal diet during pregnancy and longitudinal development of childhood asthma. Daily consumption of nut products increased the risk of asthma outcomes during the first 8 years of life. – Expectant mothers who eat nuts or nut products like peanut butter daily during pregnancy increase their children’s risk of developing asthma by more than 50 percent over women who rarely or never consume nut products during pregnancy, according to new research from the Netherlands.
The U.S. Food and Drug Administration (FDA) approves new genetic test for patients with breast cancer. – SPOT-Light HER2 CISH kit – a novel genetic test for determining whether patients with breast cancer are good candidates for treatment with the drug Herceptin (trastuzumab) has been approved by the U.S. Food and Drug Administration.
First-born babies’ higher asthma and allergy rates due to pregnancy conditions. Allergic reactions are programmed during pregnancy and then effect the disease in later life. – First-born children are at higher risk of developing asthma and allergy because of different conditions they experience in the uterus, revealed by researchers.
