Researchers reveal how podocytes may regenerate themselves during normal kidney function

Damage to podocytes -- a specialized type of epithelial cell in the kidney -- occurs in more than 90 percent of all chronic kidney disease. Now researchers at the Stanford University School of Medicine have uncovered an unexpected pathway that reveals for the first time how these cells may regenerate and renew themselves during normal kidney function.

New discovery of adult stem cells gives fresh possibilities for heart regeneration

Sydney researchers have discovered a new population of adult stem cells in the heart, which could augment the development of new regeneration and repair therapies for people who have suffered heart attack or heart failure, the leading cause of death in Australia.

Removing amyloid beta can restore sense of smell in mouse model of Alzheimer's

One of the earliest known impairments caused by Alzheimer's disease - loss of sense of smell - can be restored by removing a plaque-forming protein in a mouse model of the disease, a study led by a Case Western Reserve University School of Medicine researcher finds.

Study explores critical role of 14-3-3σ in halting breast cancer progression

New research out of McGill University's Goodman Cancer Research Centre provides compelling new evidence that a gene known as 14-3-3σ plays a critical role in halting breast cancer initiation and progression.

Counterparts of memory cells ward off microbial foes

The immune system possesses a type of cell that can be activated by tissues within the body to remind the immune system not to attack our own molecules, cells and organs, UCSF researchers have discovered.

Scientists use genetic methods to successfully repair cleft lips in mice embryos

Scientists at Weill Cornell Medical College used genetic methods to successfully repair cleft lips in mice embryos specially engineered for the study of cleft lip and cleft palate. The research breakthrough may show the way to prevent or treat the conditions in humans.

Dantrolene reduces severity of walking and balance problems linked with HD

Huntington's disease (HD) is characterized by ongoing destruction of specific neurons within the brain. It affects a person's ability to walk, talk, and think - leading to involuntary movement and loss of muscle co-ordination. New research published in BioMed Central's open access journal Molecular Neurodegeneration shows that the RyanR inhibitor Dantrolene is able to reduce the severity of walking and balance problems in a mouse model of HD.

Carefully selected young, healthy neurons can repair brain circuitry

Neuron transplants have repaired brain circuitry and substantially normalized function in mice with a brain disorder, an advance indicating that key areas of the mammalian brain are more reparable than was widely believed.

MC3R gene plays an important role in maintaining steady weight

Against the backdrop of the growing epidemic of obesity in the United States, scientists from the Florida campus of The Scripps Research Institute have made an important new discovery regarding a specific gene that plays an important role in keeping a steady balance between our food intake and energy expenditure. The study may help scientists better understand the keys to fighting obesity and related disorders such as diabetes.

Diallyl trisulfide may protect heart after attack

A component of garlic oil may help release protective compounds to the heart after heart attack, during cardiac surgery, or as a treatment for heart failure.

Scarring prevents precipitous decline in heart function after cardiac injury

After a heart attack, the portions of the heart damaged by a lack of oxygen become scar tissue. Researchers have long sought ways to avoid this scarring, which can harden the walls of the heart, lessen its ability to pump blood throughout the body and eventually lead to heart failure. But new research from the University of North Carolina at Chapel Hill School of Medicine shows that interrupting this process can weaken heart function even further.

Two proteins conspire to promote amyotrophic lateral sclerosis

Two proteins conspire to promote a lethal neurological disease, according to a study published online this week in the Journal of Experimental Medicine.

Possible link between norovirus and food allergies

Researchers at the Medical College of Wisconsin have found a possible link between norovirus, a virus that causes "stomach flu" in humans, and food allergies.

New unsuspected role for nuclear receptor corepressor protein

By knocking out a key regulatory protein, scientists at the University of California, San Diego School of Medicine and the Ecole Polytechnique Federale de Lausanne (EPFL) in Switzerland dramatically boosted insulin sensitivity in lab mice, an achievement that opens a new door for drug development and the treatment of diabetes.

Classical DCs associated with protection against atherosclerosis

Atherosclerosis, commonly referred to as "hardening of the arteries," is a major risk factor for heart attack and stroke. The cause of atherosclerosis is not well understood but, for some time, chronic inflammatory immune responses have been implicated in driving disease pathology. Now, a new study, published online on November 10th by Cell Press from the journal Immunity, identifies a type of immune cell that is not associated with promoting disease, but with protection against atherosclerosis.

Second molecular conductor discovered in some children with biliary atresia

Unexpected discovery of a new molecular signature for a destructive and often lethal pediatric liver disease may lead to a new therapeutic target for the hard-to-treat condition.

'Second hit' determines immune response against developing Burkitt's lymphoma

The human c-myc gene encodes a transcription factor (MYC) involved in the regulation of a vast number of other genes - it has been estimated that the transcription of about one in six genes is somehow under the control of MYC.

Hirano bodies may play a protective role in progression of Alzheimer's

Hirano bodies are almost indescribably tiny objects found in nerve cells of people suffering from conditions such as Alzheimer's, mad cow and Lou Gehrig's diseases. Yet for decades, researchers weren't sure if these structures helped cause the conditions or appeared after onset of the disease and had some other role.

Smoking primes the brain for cocaine addiction: Study

The study comes from the National Institute on Drug Abuse in Maryland that is the first of its kind to show how nicotine can change the brain in a way that enhances the behavioral effects of cocaine. It could help explain why so many drug-using teenagers tend to start with cigarettes and alcohol before moving on to more illegal substances.
