New genetics promises to change faulty genes of future generations by using "designer sperm”

Bethesda, MD-Get ready: The "new genetics" promises to change faulty genes of future generations by introducing new, functioning genes using "designer sperm." A new research report appearing online in The FASEB Journal, shows that introducing new genetic material via a viral vector into the sperm of mice leads to the presence and activity of those genes in the resulting embryos.

ATN-224 inhibitor reduces tumor sizes in mouse model of lung adenocarcinoma

Many cancers have adapted to cope with high levels of immune system-produced free radicals, also referred to as reactive oxygen species, by overproducing antioxidant proteins. One of these proteins, superoxide dismutase 1, is overproduced in lung adenocarcinomas and has been implicated as a target for chemotherapy.

New finding links obesity and high-fat, high-sugar diets with changes in inflammatory status

Scientists have moved a step closer to an "obesity drug" that may block the effects of diets high in sugar and fats. In a new research report published in the December 2013 issue of The FASEB Journal, scientists show that there is an abnormal amount of an inflammatory protein called PAR2 in the abdominal fat tissue of overweight and obese humans and rats.

Certain hormones which are increased during exercise may help improve memory

Researchers at Boston University School of Medicine (BUSM) have found further evidence that exercise may be beneficial for brain health and cognition. The findings, which are currently available online in Behavioural Brain Research, suggest that certain hormones, which are increased during exercise, may help improve memory.

Oxygen levels play critical role in determining effectiveness of anti-inflammatory drugs

A new research discovery published in the December 2013 issue of the Journal of Leukocyte Biology yields an important clue toward helping curb runaway inflammation. Oxygen levels play a critical role in determining the severity of the inflammatory response and ultimately the effectiveness of anti-inflammatory drugs.

VRC scientists receive $2.2M grant to develop new resin composite dental fillings

The American Dental Association and the ADA Foundation today announced that the foundation's Anthony Volpe Research Center (VRC) received a five-year, $2.2 million grant from the National Institute of Dental and Craniofacial Research (NIDCR) to develop new resin composite dental fillings.

Researchers create computer algorithm to identify specific genes involved in breast cancer growth

Researchers from the University of Alberta and Alberta Health Services have created a computer algorithm that successfully predicts whether estrogen is sending signals to cancer cells to grow into tumours in the breast. By finding this hormone receptor, known as estrogen receptor positive, physicians can prescribe anti-estrogen drug therapies, improving patient outcomes.

Valproic acid can enhance neuronal regeneration following brachial plexus root avulsion

Brachial plexus root avulsion is the most serious type of peripheral nerve injury. Valproic acid has been shown to exert neuroprotective effects and promote neurite outgrowth in several peripheral nerve injury models. However, whether valproic acid can exert its beneficial effect on neurons after brachial plexus avulsion injury is currently unknown.

Vitamin D2 supplementation is promising treatment for pain, depression in type 2 diabetes

Vitamin D decreases pain in women with type 2 diabetes and depression, according to a study conducted at Loyola University Chicago. These findings were presented at an Oct. 24, 2013 research conference at Loyola's Health Sciences Campus.

Newly identified protein could prove promising new drug target for AIDS

Researchers have identified a protein that causes loss of function in immune cells combatting HIV. The scientists report in a paper appearing online Dec. 2 in the Journal of Clinical Investigation that the protein, Sprouty-2, is a promising target for future HIV drug development, since disabling it could help restore the cells' ability to combat the virus that causes AIDS.

Recently discovered humanin peptide could lead to powerful new treatments for diabetes

Even if the obesity trend cannot be reversed, here's hope that it's partner in crime-diabetes-might be thwarted. New research published in the December 2013 issue of The FASEB Journal shows how a recently discovered human peptide, called humanin, could lead to powerful new treatments for some people living with diabetes.

USC scientists show gene-environment interaction augments risk for developing autism

Exposure to air pollution appears to increase the risk for autism among people who carry a genetic disposition for the neurodevelopmental disorder, according to newly published research led by scientists at the Keck School of Medicine of the University of Southern California.

Scientists transform human stem cells into functional lung and airway cells

For the first time, scientists have succeeded in transforming human stem cells into functional lung and airway cells. The advance, reported by Columbia University Medical Center researchers, has significant potential for modeling lung disease, screening drugs, studying human lung development, and, ultimately, generating lung tissue for transplantation.

Researchers discover promising new approach for colorectal cancer treatment

Scientists and surgeons at Princess Margaret Cancer Centre have discovered a promising new approach to treating colorectal cancer by disarming the gene that drives self-renewal in stem cells that are the root cause of disease, resistance to treatment and relapse. Colorectal cancer is the third leading cause of cancer-related death in the Western world.

Nanosponge vaccine blocks adverse effects of alpha-haemolysin toxin from MRSA

Nanosponges that soak up a dangerous pore-forming toxin produced by MRSA (methicillin-resistant Staphylococcus aureus) could serve as a safe and effective vaccine against this toxin. This "nanosponge vaccine" enabled the immune systems of mice to block the adverse effects of the alpha-haemolysin toxin from MRSA-both within the bloodstream and on the skin. Nanoengineers from the University of California, San Diego described the safety and efficacy of this nanosponge vaccine in the December 1 issue of Nature Nanotechnology.

Researchers examine how spindle apparatus self-organizes

Researchers at Waseda University in Japan have identified key information to help explain the formation of the "spindle apparatus", a structure required for cell division. Their findings shed light on the mechanisms behind "self-organization" - an essential characteristic of biological structures.
