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.
Study indicates that a common virus could cause high blood pressure – Cytomegalovirus affects majority of adults worldwide. – A new study suggests for the first time that cytomegalovirus (CMV), a common viral infection affecting between 60 and 99 percent of adults worldwide, is a cause of high blood pressure, a leading risk factor for heart disease, stroke and kidney disease.
Genes that influence start of menstruation identified for first time – Two genes clarify the genetic control of female sexual maturation, and point to regulatory mechanisms involved in human growth and development. – Researchers from the Peninsula Medical School, along with collaborators from research institutions across Europe and the United States, have for the first time identified two genes that are involved in determining when girls begin menstruation.
Researchers identify key proteins needed for ovulation – study reveals essential step in female reproductive process. – Researchers from the National Institutes of Health and other institutions have identified in mice two proteins essential for ovulation to take place.
Developing a genetic test for pregnancy risks – analysis of mum’s and dad’s DNA can predict and enhance pregnancy success. – University of Adelaide researchers are developing a world-first genetic test that can predict which pregnancies are at risk of complications long before symptoms arise.
Suit charges that Myriad Genetics BRCA1 and BRCA2 patents interfere with the free flow of information and knowledge in violation of the First Amendment and that human genes are ‘products of nature’ that cannot be patented. – The Association for Molecular Pathology (AMP) announced that it is working with the American Civil Liberties Union (ACLU) and the Public Patent Foundation to bring a lawsuit charging that patents on two human genes associated with breast and ovarian cancer are unconstitutional and should be invalidated.
UNC study identifies genetic cause of most common form of breast cancer – Defects in the p18 gene have been observed in different types of human cancer. – The discovery of tumor-suppressor genes has been key to unlocking the molecular and cellular mechanisms leading to uncontrolled cell proliferation ? the hallmark of cancer.
Genes found to play a role in breast cancer’s spread to the brain – New research led by investigators at Memorial Sloan-Kettering Cancer Center (MSKCC) identifies three genes that specifically mediate the metastasis, or spread, of breast cancer to the brain and illuminates the mechanisms by which this spread occurs.
Late motherhood boosts family lifespan. Same genes linked to longevity and births after age 45. – Women who have babies naturally in their 40s or 50s tend to live longer than other women. Now, a new study shows their brothers also live longer, but the brothers’ wives do not, suggesting the same genes prolong lifespan and female fertility, and may be more important than social and environmental factors.
Early Detection Of Melanoma Plus Regular Skin Exams Is Vital For Beating Disease. Dermatologists Offer Advice for Reaching Five-Year Survival Mark. – On television’s popular “Grey’s Anatomy,” Dr. Izzie Stevens faces a grim diagnosis: stage IV metastatic melanoma. As the drama unfolds, viewers get a glimpse at why patients with the deadliest form of skin cancer ? in the most advanced stage of diagnosis ? face a mere 10-month median survival rate.
World’s largest DNA scan for autism uncovers new gene variant for disorder. Risk of autism tied to genes that influence brain cell connections. – Researchers have identified a new gene variant that is highly common in autistic children. Gene, known as CDH10, is most active in key regions that support language, speech and interpreting social behavior.
Autism may be linked to being firstborn, breech births or moms 35 or older. Study looked at group of Utah 8-year-olds. – Children who are firstborn or breech or whose mothers are 35 or older when giving birth are at significantly greater risk for developing an autism spectrum disorder, University of Utah School of Medicine researchers have reported in a new study with Utah children.
Gladstone scientists identify key factors in heart cell creation. Sequence of transcription factors may drive proces to repair damaged hearts. – Scientists at the Gladstone Institute of Cardiovascular Disease have identified for the first time key genetic factors that drive the process of generating new heart cells.
