Genes linked to major brain functions and disorders

An international team of researchers have found the genes that increase or reduce the risk of certain mental illnesses and Alzheimer's disease. They claim that some genes that may explain individual differences in brain size and intelligence as well. The team of more than 200 scientists at 100 institutions said this was the largest-ever brain study to date.

Study calls for research into all aspects of follow-up care in lung cancer

Scientist say there is an urgent need for research into all aspects of follow-up care in lung cancer. The study presented in the May 2012 issue of the International Association for the Study of Lung Cancer's (IASLC) Journal of Thoracic Oncology focused on different follow-up strategies for patients with lung cancer.

Keck Foundation awards UF $1M to study how proteins in cells are made

The Center for NeuroGenetics at the University of Florida has received a competitive $1 million grant from the W.M. Keck Foundation to study a new idea that challenges conventional understanding of how proteins in cells are made, and their impact on inherited diseases.

Gene function preserved despite structural differences in the DNA

Chloroplasts, the plant cell's green solar power generators, were once living beings in their own right. This changed about one billion years ago, when they were swallowed up but not digested by larger cells. Since then, they have lost much of their autonomy.

Significant skull variation between groups in close proximity

In order to accurately identify skulls as male or female, forensic anthropologists need to have a good understanding of how the characteristics of male and female skulls differ between populations. A new study from North Carolina State University shows that these differences can be significant, even between populations that are geographically close to one another.

Disruption of key cellular functions produces physiologic and behavioral responses

Two Massachusetts General Hospital (MGH)-based research teams, along with a group from the University of California at San Diego, have discovered that animals have a previously unknown system for detecting and responding to pathogens and toxins. In three papers published in the journals Cell and Cell Host & Microbe, the investigators describe finding evidence that disruptions to the core functions of animal cells trigger immune and detoxification responses, along with behavioral changes.

Biologists decipher novel functions of metal-binding molecule nicotianamine

In order to survive, plants should take up neither too many nor too few minerals from the soil. New insights into how they operate this critical balance have now been published by biologists at the Ruhr-Universit-t in a series of three papers in the journal The Plant Cell. The researchers discovered novel functions of the metal-binding molecule nicotianamine.

$Researchers identify 32 genetic regions associated with osteoporosis, fracture$

Researchers identify 32 genetic regions associated with osteoporosis, fracture

Thirty-two previously unidentified genetic regions associated with osteoporosis and fracture have been identified by a large, worldwide consortium of researchers, including Stanford Prevention Research Center chief John Ioannidis, MD, DSc. Variations in the DNA sequences in these regions confer either risk or protection from the bone-weakening disease. Many, but not all, of the regions encode proteins involved in pathways known to involve bone health.

Two research studies on genetic components of Alzheimer's

Two research studies, co-led by UC Davis neurologist Charles DeCarli and conducted by an international team that included more than 80 scientists at 71 institutions in eight countries, has advanced understanding of the genetic components of Alzheimer's disease and of brain development. Both studies appear in the April 15 edition of the journal Nature Genetics.

New genes may explain individual differences in brain size and intelligence

In the world's largest brain study to date, a team of more than 200 scientists from 100 institutions worldwide collaborated to map the human genes that boost or sabotage the brain's resistance to a variety of mental illnesses and Alzheimer's disease.

Researchers identify new mechanism by which colon cancer develops

A team of researchers at Case Western Reserve University School of Medicine have identified a new mechanism by which colon cancer develops. By focusing on segments of DNA located between genes, or so-called "junk DNA," the team has discovered a set of master switches, i.e., gene enhancer elements, that turn "on and off" key genes whose altered expression is defining for colon cancers.

Study reveals genetic predictors of bone health and osteoporosis

An international consortium of researchers have identified a group of genes associated with the development of osteoporosis, a debilitating bone disease that cripples more than 10 million Americans a year and costs the U.S. healthcare system an estimated $17 billion annually.

Four loci appear to decrease hippocampal volume

An international team of researchers led by Boston University School of Medicine (BUSM) has identified four loci that appear to be associated with decreasing the volume of the hippocampus.

First study to show genetic adaptation of human fat metabolism

About 300 000 years ago humans adapted genetically to be able to produce larger amounts of Omega-3 and Omega-6 fatty acids. This adaptation may have been crucial to the development of the unique brain capacity in modern humans. In today's life situation, this genetic adaptation contributes instead to a higher risk of developing disorders like cardiovascular disease.

Study investigates genetic factors and smoking exposure in Japanese lung cancer patients

Previous research has shown that Asian patients with lung cancer are more likely to harbor epidermal growth factor receptor (EGFR) mutations. Furthermore, Asian patients with lung cancer are more likely to be non-smokers than Western patients with lung cancer. Research in the May 2012 issue of the International Association for the Study of Lung Cancer's (IASLC) Journal of Thoracic Oncology goes deeper, investigated genetic factors and smoking exposure in Japanese lung cancer patients.

Huntington’s disease may protect against cancer: Study

Dr Jianguang Ji, Lund University, and Skåne University Hospital, Malmö, Sweden, and colleagues investigated data from the Swedish Cancer Registry. Researchers analyzed Swedish hospital data from 1969 to 2008. They found 1,510 patients with Huntington's disease. During the study period, 91 of those patients subsequently developed cancer. The authors said that was 53% lower than the levels expected for the general population.

Toxic plants and animal products found in traditional Chinese medicines

A study has found that some traditional Chinese medicines contain potentially poisonous plants, unlabelled ingredients and bits of endangered animals. This has triggered a bid for routine testing and tighter regulation of complementary medicines.

Ovarian cancer screening may not be needed on routine basis for all women says panel

In its latest review since 2004 of the benefits and harms of ovarian cancer screening, the United States Preventive Services Task Force found no new evidence to support routine screening.

ALL induction treatment failure should not be an automatic indication for bone marrow transplant

International study that included St. Jude Children's Research Hospital reports some young acute lymphoblastic leukemia patients who fail induction therapy can achieve high cure rates without bone marrow transplantation.

Consumption of long-chain omega-3 PUFAs lowers risk of colorectal polyps in women

New research finds that omega-3 polyunsaturated fatty acids (PUFAs) found in seafood (long-chain omega-3s) may reduce the risk of precancerous colorectal polyps in women, enhance the muscular benefits of strength training in older women and improve eye health after corneal surgery.
