(Medical Xpress)—Cornell researchers have uncovered the basic cell biology that helps explain heart defects found in diseases known as laminopathies, a group of some 15 genetic disorders that include forms of muscular dystrophy and between 5 percent and 10 percent of all cases of inherited heart disease. http://medicalxpress.com/news/2013-05-laminopathies-key-components-disease-mechanism.html Medical research Tue, 07 May 2013 07:26:31 EST news287130376 Fresh insights into the protective seal that surrounds the DNA of our cells could help develop treatments for inherited muscle, brain, bone and skin disorders. http://medicalxpress.com/news/2013-02-cell-discovery-key-inherited-diseases.html Medical research Tue, 26 Feb 2013 11:39:36 EST news281101152 (Medical Xpress)—A diverse team of biologists has shown using induced pluripotent stem cells (iPSCs) that a gene mutation that causes malformations in the structure of the nuclear envelope of neural cells, is associated with Parkinson's disease. In their paper published in the journal Nature, they describe how they found iPSC cells taken from Parkinson's patients over time demonstrated the same cell disruption found in neural cells taken from other deceased patient's with the disease. They also found that by introducing a compound known to disrupt the gene mutation, that they could reverse the cell malformation. http://medicalxpress.com/news/2012-10-stem-cells-neural-cell-disruption.html Parkinson's & Movement disorders Thu, 18 Oct 2012 09:40:03 EST news269768714 Each time a cell divides -- and it takes millions of cell divisions to create a fully grown human body from a single fertilized cell -- its chromosomes have to be accurately divvied up between both daughter cells. Researchers at the Stowers Institute for Medical Research used, ironically enough, the single-celled organism Saccharomyces cerevisiae -- commonly known as baker's yeast -- to gain new insight into the process by which chromosomes are physically segregated during cell division. http://medicalxpress.com/news/2011-11-gain-insight-chromosome.html Genetics Thu, 17 Nov 2011 18:40:02 EST news240774017 A new study identifies the mutation that underlies a rare, inherited accelerated-aging disease and provides key insight into normal human aging. The research, published by Cell Press online May 5 in the American Journal of Human Genetics, highlights the importance of a cellular structure called the "nuclear envelope" in the process of aging. http://medicalxpress.com/news/2011-05-mutation-insight-molecular-mechanisms-aging.html Genetics Thu, 05 May 2011 13:06:44 EST news223819543
