The peroxisome, a tiny intracellular organelle, was discovered in the mid-1960s, and for nearly 50 years scientists were unsure of how it and TSC2 worked. Now a team at Texas A&M Health Science Center (TAMHSC) Institute of Biosciences and Technology (IBT) know that TSC2 keeps peroxisomes at the right levels to maintain healthy cells. Houston, TX (PRWEB) October 10, 2013 When it comes to survival on the cellular level, mysteries have abounded for decades. In a paper published in the...

Tadpole And The Tail: Studying The Secrets Of Human Healing
2013-01-14 10:08:34

Brett Smith for redOrbit.com - Your Universe Online Humans have the capacity to regenerate tissue after suffering an injury, but many animals have the ability to regenerate whole limbs after an amputation. A group of UK researchers decided to look into this ability in tadpoles, which can regrow a tail that has been severed. Their results proved to be somewhat counter intuitive–showing that a molecule previously thought to be harmful to cells is involved in the process....

Antidepressant Paroxetine Treats Diabetes
2012-12-14 22:05:43

Lee Rannals for redOrbit.com — Your Universe Online Researchers have found the commonly used antidepressant drug paroxetine could become a therapy for the vascular complications of diabetes. The scientists made their discovery after screening 6,766 clinically used drugs and pharmacologically active substances. "We developed this assay and used it to test literally every single existing drug and a good selection of other biologically active compounds," UTMB professor Csaba...

Promising Therapy For Huntington’s Disease Developed
2012-11-01 15:43:50

Lawrence Berkeley National Laboratory Initial results in mice could lead to new way to fight neurodegenerative diseases There´s new hope in the fight against Huntington´s disease. A group of researchers that includes scientists from the U.S. Department of Energy´s Lawrence Berkeley National Laboratory (Berkeley Lab) have designed a compound that suppresses symptoms of the devastating disease in mice. The compound is a synthetic antioxidant that targets mitochondria, an...

Why do we age, and what makes some of us live longer than others? For decades, researchers have been trying to answer these questions by elucidating the molecular causes of aging. One of the most popular theories is that the accumulation of oxygen radicals over time might be the underlying culprit in aging. Oxygen radicals are chemically reactive molecules that can damage cellular components such as lipids, proteins and nucleic acids, resulting in "oxidative stress." The possible link...

Drugs target Nox2 enzyme directly instead of acting as antioxidants Scientists at Emory University School of Medicine have identified a new type of anti-inflammatory compound that may be useful in treating a wide range of conditions, including neurodegenerative and autoimmune diseases. These compounds inhibit the enzyme Nox2, part of a family of enzymes responsible for producing reactive oxygen species (ROS). "Nox2 inhibitors could be valuable with many conditions where inflammation...

Previously unknown repair byproduct could be ℠master regulator´ of many basic cell processes University of Texas Medical Branch at Galveston researchers have found a surprising connection between a key DNA-repair process and a cellular signaling network linked to aging, heart disease, cancer and other chronic conditions. The discovery promises to open up an important new area of research – one that could ultimately yield novel treatments for a wide variety of diseases....

Lee Rannals for RedOrbit.com NASA has been in the field of space sciences for 53-years, but the space agency may be diving into the world of cosmetics unexpectedly. The U.S. space agency developed a fruit drink, known as AS10, to protect astronauts from radiation, but a new study shows astronauts are not the only humans who can benefit from the concoction. Researchers set out to test the affect AS10 may have on its 180 participants who do not frequently make trips outside the Earth's...
