IVF research led by New Hampshire Reproductive Center fertility doctor, Kristen P Wright, MD, indicates IVF process effects DNA methylation associated with two syndromes (PRWEB) July 22, 2011 Since the birth of the first IVF baby in 1978, more than 3 million children have been born worldwide following IVF treatments. Numerous studies have been conducted to assess the overall health of children born after IVF. The majority of these studies on the safety of IVF have been reassuring....

For decades, scientists have known that DNA consists of four basic units -- adenine, guanine, thymine and cytosine. Those four bases have been taught in science textbooks and have formed the basis of the growing knowledge regarding how genes code for life. Yet in recent history, scientists have expanded that list from four to six. Now, with a finding published online in the July 21, 2011, issue of the journal Science, researchers from the UNC School of Medicine have discovered the seventh and...

Hallmark of cancer cells Scientists from the Hebrew University have identified the molecular basis for DNA breakage, a hallmark of cancer cells. The findings of this research have just been published in the journal Molecular Cell. The DNA encodes the entire genetic information required for building the proteins of the cell. Hence, DNA breaks disrupt the proteins and lead to changes in the cell function. These changes can lead to defects in the control of cellular proliferation resulting in...

Results suggest novel approach to developing targeted cancer therapies Scientists at Fox Chase Cancer Center have discovered a new mechanism used by cells in the body to turn on silenced genes. This process is critical in preventing the development of cancer"”suggesting the possibility of new therapies that might target the specific changes underlying the disease. The findings will be published online in the journal Cell on June 30, 2011. The process investigated by Alfonso Bellacosa,...

GREEN BAY, Wis., June 23, 2011 /PRNewswire/ -- Dr. Ajay Goel, Ph.D., Director of Epigenetics and Cancer Prevention at the Gastrointestinal Research Center at Baylor University Medical Center in Dallas, TX, has announced plans for a series of upcoming studies to continue to unlock the mechanisms by which curcumin prevents cancer via its influence on epigenetic activity. While many people believe there is a strong genetic influence in the development of cancer, Dr. Goel states this is...

The study may allow finding the unknown origin of metastasis and improving treatments Until a decade, it was believed that differences between people were due solely to the existence of genetic changes, which are alterations in the sequence of our genes. The discoveries made during these last ten years show that beings with the same genetics like the twins and cloned animals may have different characteristics and disease due to epigenetic changes. Epigenetics involves chemical signatures that...

(Ivanhoe Newswire) --Children whose mothers and grandmothers smoked during pregnancy are more likely to suffer from childhood asthma and researchers may have just figured out why. A new study shows changes in a process called DNA methylation, that occurs before birth, may be a root cause. DNA methylation can alter a gene's typical function, and the altered genes can be passed along from parent to child. For this study, researchers observed DNA methylation-related changes in the AXL gene in...

Children whose mothers smoked while pregnant are at an increased risk of developing asthma, possibly because smoking while pregnant can change the structure of the child's DNA, weakening the immune system, according to a study by researchers at the University of Southern California. The research suggests that changes in a process called DNA methylation, which can alter a gene's normal function, may be responsible for the increased risk. The altered genes can be passed along from parent to...

Children whose mothers or grandmothers smoked during pregnancy are at increased risk of asthma in childhood, but the underlying causes of this are not well understood. Now a new study indicates changes in a process called DNA methylation that occurs before birth may be a root cause. The study will be presented at the ATS 2011 International Conference. DNA methylation is a process that can alter a gene's usual function. These altered genes can be passed along from parent to child. In this...

Discovery, which has implications for cancer, explains why some genes are silenced Japanese and U.S. scientists in the young field of epigenetics Thursday reported a rationale as to how specific genes are silenced and others are not. Because this effect can be reversed, it may be possible to devise therapies for cancer and other diseases using this information. The NOVA U.S. public television program described epigenetics as "The Ghost In Your Genes." It is the study of changes in gene...


Word of the Day
omphalos
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
  • A sacred stone in the temple of Apollo at Delphi, believed by the Greeks to mark the 'navel' or exact center-point of the earth.
'Omphalos' comes from the ancient Greek.
