Genetic Discovery Will Revolutionize Understanding Of Gene Expression
Over the past decade, research in the field of epigenetics has revealed that chemically modified bases are abundant components of the human genome and has forced us to abandon the notion we’ve had since high school genetics that DNA consists of only four bases. Their report, published in the journal Cell , shows that messenger RNA (mRNA), long thought to be a simple blueprint for protein production, is often chemically modified by addition of a methyl group to one of its bases, adenine. Indeed, as part of the study, the researchers demonstrated that the obesity risk gene, FTO (fat mass and obesity-associated), encodes an enzyme capable of reversing this modification, converting m6A residues in mRNA back to regular adenosine. Olivier Elemento, assistant professors from the Department of Physiology and Biophysics and Computational Genomics in Computational Biomedicine at Weill Cornell Medical College, then developed computational algorithms to reveal the identity of each of these methylated mRNAs. The Weill Cornell researchers don’t know how the thousands of m6As they detected in humans work to control the function of mRNAs, but they do note that the m6As are located near “stop codons” in mRNA sequences. The investigators are currently working to understand how defective regulation of m6A in patients with FTO mutations causes obesity and metabolic disorders, and they are also developing tests to rapidly identify compounds that inhibit FTO activity.
Gene Related To Autism, Schizophrenia And Obesity Isolated By Zebrafish Study
Katsanis knew that a region on chromosome 16 was one of the largest genetic contributors to autism and schizophrenia, but a conversation at a European medical meeting pointed him to information that changes within that same region of the genome also were related to changes in a newborn’s head size. The researchers transplanted a common duplication area of human chromosome 16 known to contain 29 genes into zebrafish embryos and then systematically turned up the activity of each transplanted human gene to find which might cause a small head (microcephaly) in the fish. It took the team a few months to dissect such a “copy number variant” - an alteration of the genome that results in an abnormal number of one or more sections of chromosomal DNA. The current study suggests that KCTD13 is a major contributor to some cases of autism, but also points to the synergistic action of this gene with two other genes in the region, named MVP and MAPK3, Katsanis said.

For Medication Disposal, New Advice Is Trash Beats Take-Back
Returning extra medicine to the pharmacy for disposal might not be worth the extra time, money or greenhouse gas emissions, according to a University of Michigan study that is the first to look at the net effects of so-called take-back programs. The new evidence suggests that discarding unused drugs in the trash is a better option to limit the risk of poisoning and at the same time curb pollution of both water and air. If half of people threw away unused medications and half took them back to the drug store, the amount of active pharmaceutical ingredients in the environment would be reduced by 93 percent compared with today. Drugs that aren’t returned tend to stay in the medicine cabinet, defeating the goal of getting unused medications out of the home quickly, the researchers say.
New Inflammation Hormone Link May Pave Way To Study New Drugs For Type 2 Diabetes
A new link between obesity and type 2 diabetes found in mice could open the door to exploring new potential drug treatments for diabetes, University of Michigan Health System research has found. But the U-M study suggests that glucagon - a pancreas-produced hormone that has the opposite effect of insulin by raising blood glucose levels - may also provide a powerful pathway to preventing and treating the increasingly prevalent disease. Insulin resistance - which reduces the body’s ability to decrease blood glucose - has been the main hallmark of type 2 diabetes, which is the most common form of diabetes in the United States afflicting millions of Americans. People can lose weight for many reasons, perhaps intentionally through exercise training for a sports event, for health reasons, just to look better, or unintentionally as may occur because of an underlying disease.

CHORI Bar Improves Cognitive and Metabolic Benefits In Just 2 Weeks
Ames, PhD, led a team of scientists at the Children’s Hospital Oakland Research Institute’s (CHORI) Nutrition & Metabolism Center to develop the CHORI bar, a low-calorie fruit based vitamin and mineral nutrition bar that is designed to help restore optimal nutritional balance in those with poor eating habits and to assist them in adopting a healthier diet. The first research paper on the CHORI bar is published in the online issue of FASEB Journal (the Journal of the Federation of American Societies for Experimental Biology) ahead of the August issue print version. Ames, who studied the association of vitamins and minerals with metabolic processes for years, hypothesized that small deficiencies could contribute to metabolic imbalances, which raise the risk of obesity and aging-related diseases like diabetes , cancer , and heart disease and proposed the Triage Theory in 2006, which offered a mechanistic reason linking modest vitamin/mineral deficiencies to disease. Since the project was initiated, 11 small pilot trials have been performed to refine the bar and improvements are continuing to expand the number of disease risk biomarkers favorably impacted by the bar. The CHORI-bar combines parts of the Mediterranean diet together with 5-methyl-tetrahydrofolate, the most biologically active form of folate, which is expected to bypass the need for high folate levels to maintain healthy levels of homocysteine in those with the TT MTHFR polymorphism. Aside from having the potential to make a positive impact on public health, the CHORI bar also acts as a research tool that is able to shed light on the bar’s food component mechanisms in terms of how they interact with metabolic pathways to achieve a favorable effect on disease-relevant biomarkers.
New Twist On Ancient Math Problem Could Improve Medicine, Microelectronics
A hidden facet of a math problem that goes back to Sanskrit scrolls has just been exposed by nanotechnology researchers at the University of Michigan and the University of Connecticut. Called the “filling problem,” it seeks the best way to cover the inside of an object with a particular shape, such as filling a triangle with discs of varying sizes. In their paper, published online in Physical Review Letters , the researchers report the rules for how to find the ideal size and spacing of the discs that fill a shape. In the future, they expect to reveal an algorithm that can take the desired shape and the number of discs, or the shape and percentage of the area to be filled, and spit out the best pattern to fill it. Extending the approach into three dimensions, Glotzer proposes that it could decide the placement of wireless routers in a building where the signal must not be available to a potential hacker in the parking lot.
High Volume Stroke Centers Provide Faster Treatment And Have Superior Outcomes
The team gathered data on risk factors likely to influence the success of treatment, such as high cholesterol , diabetes , high blood pressure and abnormal heart rhythms ( atrial fibrillation ), as well as information on age and sex. In addition, the researchers examined the size and location of the clot, how quickly treatment was administered, as well as how fast blood flow returned to normal (repercussion). After a CT scan of the brain was performed, a catheter was inserted through the groin and the clot buster drug was injected into the affected artery. After examining only patients referred from within the hospital, the team found that only 20 of the 112 patients who received treatment at the low volume center would have met the recommend 120 minute door to need time compared to 40 out of 100 patients at high volume centers.
New Animal Model Developed For ADHD
To better understand the cause of ADHD and to identify methods to prevent and treat it, researchers at Oregon Health & Science University (OHSU) and OHSU’s Oregon National Primate Research Center have developed a new form of specially bred mouse that mimics the condition. The research is published in the current edition of the PLoS ONE , a journal of the Public Library of Science. The specific gene that was studied in this research is called SynCAM1, which is found in glial cells - a type of cell in the central nervous system involved in cellular communication. When hypertension is eliminated by crossing SHR rats to another commonly studied rat breed, the resulting rat has normal blood pressure but no longer responds to the methylphenidate in a way that humans with ADHD do.
Facebook Addiction - New Psychological Scale
This is particularly relevant given that Facebook is now more than a social networking site (for instance users can watch videos and films, gamble and play games on the site) and social networking is not confined to Facebook. The Norwegian team also finds that people who are more organized and ambitious tend not to become addicted to Facebook, and are more likely to use social media as an integral part of work and networking activity. Dr Mark D Griffiths, Professor of Gambling Studies in the International Gaming Research Unit at Nottingham Trent University in the UK, writes a response to the study in the same issue of the journal. Another point Griffiths makes is that we need to clarify what it is that people on social networks are really addicted to, and what, for example, a Facebook addiction tool is really measuring. There is a big difference between addictions on the Internet, and addiction to the Internet, he adds, and the same argument now holds true for Facebook, as it does for mobile phones.
Droplet Array Sheds Light On Drug-Resistant Cancer Stem Cells
Researchers at the Institute of Bioengineering and Nanotechnology (IBN), the world’s first bioengineering and nanotechnology research institute, have developed a miniaturized biochip for investigating the effect of drugs on cancer stem cells (CSCs). Using the Droplet Array, the IBN researchers investigated the drug responses of CSCs extracted from breast, liver and colon cancer cells. The study of cancer stem cells, in particular, is an exciting application of this technology for both the academic and pharmaceutical industries. Designed for ease of use, this miniaturized biochip is compatible with existing laboratory instruments, such as plate readers and microscopes, and reduces the set-up cost and the need to purchase additional equipment when adapting to this new technology. Nanotechnology, the manipulation of matter at the atomic and molecular scale to create materials with remarkably varied and new properties, is a rapidly expanding area of research.
