Study finds that TPC2 protein regulates melanin production

A year and a half ago, researchers at Brown University found a molecular gas pedal for melanin production. Now they've found a brake. For scientists, the finding deepens not only the basic understanding of how eyes, skin and hair gain color, but also what perhaps can be done in disorders, such as albinism, when that doesn't happen.

Inhibiting autophagy can effectively block tumor cell migration, breast cancer metastasis

Researchers from the University of Chicago have shown that inhibiting autophagy, a self-devouring process used by cells to degrade large intra-cellular cargo, effectively blocks tumor cell migration and breast cancer metastasis in tumor models.

Chronic use of antacid drugs may speed up aging of blood vessels

Chronic use of some drugs for heartburn and gastroesophageal reflux (GERD) speeds up the aging of blood vessels, according to a published paper in Circulation Research, an American Heart Association journal.

High-level quantum chemical computations help unravel underlying mechanism of hepatocellular toxicity

Balasubramanian and Basak have recently reported quantum chemical computations that enhance our understanding of mechanisms for the causes of liver toxicity. Hepatocellular carcinoma is one of the most common forms of cancer, and the primary cause has been attributed to liver fibrosis by chemical toxins, which is followed by liver cirrhosis.

Salk scientists reveal how cellular fuel gauge plays unexpected role in development

Salk scientists have revealed how a cellular "fuel gauge" responsible for monitoring and managing cells' energy processes also has an unexpected role in development. This critical link could help researchers better understand cancer and diabetes pathways.

Study describes precise mechanisms that enable TB bacteria to persist in the body

Bacteria that cause tuberculosis trick immune cells meant to destroy them into hiding and feeding them instead. This is the result of a study led by researchers from NYU Langone Medical Center and published online April 18 in Nature Immunology.

Oxidized mitochondrial nucleoids released from neutrophils may contribute to SLE pathogenesis

Researchers at the Baylor Institute for Immunology Research have discovered that the neutrophils of systemic lupus erythematosus (SLE) patients release oxidized DNA from their mitochondria that can stimulate an unwanted immune response.

Abnormally active Rab5 protein leads to early development of neurodegenerative disease

Writing in the April 11 issue of The Journal of Clinical Investigation, researchers at University of California, San Diego School of Medicine say abnormalities in a protein that helps transport and sort materials inside cells are linked to axonal dysfunction and degeneration of neurons in Alzheimer's disease (AD) and Down syndrome (DS).

Brain's immune cells play direct role in development of amyotrophic lateral sclerosis

Cedars-Sinai research scientists have found that immune cells in the brain play a direct role in the development of amyotrophic lateral sclerosis, or ALS, offering hope for new therapies to target the neurodegenerative disease that gradually leads to paralysis and death.

Researchers find new innate immunity pathway that protects mammals from viral oncogenesis

Building upon earlier research, investigators at UT Southwestern Medical Center and their collaborators have identified a new innate immunity pathway that protects mammals from viral oncogenesis, the process by which viruses cause normal cells to become cancerous.

Researchers unravel biochemical action of antimalarial drug

Malaria is a worldwide menace. According to the Centers for Disease Control and Prevention, over 500,000 individuals died from malaria in 2013 alone. While treatments for the disease exist, cures can also take a hefty physical toll.

Pioneering technique shows promise for new medical diagnostics, targeted drug delivery

Living systems rely on a dizzying variety of chemical reactions essential to development and survival. Most of these involve a specialized class of protein molecules--the enzymes.

Johns Hopkins study shows high doses of cocaine kill brain cells

Working with mice, researchers at Johns Hopkins have contributed significant new evidence to support the idea that high doses of cocaine kill brain cells by triggering overactive autophagy, a process in which cells literally digest their own insides. Their results, moreover, bring with them a possible antidote, an experimental compound dubbed CGP3466B.

UAB's Undiagnosed Diseases Program finds answers for mysterious health issues

Stephanie and Christopher Smith have been on a long, difficult and often frustrating journey to find answers for the mysterious health issues of their children. It started 24 years ago when their third child, Gage, was born. Gage, his younger brother Aiden and then sister Mandalynn, now 13, all developed mysterious symptoms that mystified doctors.

Scientists uncover novel strategy to block cancer's spread, restore tumor vulnerability to chemotherapy

St. Jude Children's Research Hospital scientists have discovered how an aggressive tumor of the muscle and soft tissue hijacks an export pathway in cells to lay the groundwork for cancer progression and resistance to chemotherapy.

VCU Massey Cancer Center scientists reveal signaling process that leads to excessive growth of cancer

The gene p53 has been described as the "guardian of the genome" due to its prominent role in preventing genetic mutations. More than half of all cancers are thought to originate from p53 mutations or loss of function, and now a recent study by VCU Massey Cancer Center scientist Richard Moran, Ph.D., explains why.

New CRC aims to better understand autophagy at molecular and cellular level

The German Research Foundation (Deutsche Forschungsgemeinschaft/DFG) has approved 11 M € for the next four years for establishing a CRC on selective autophagy under the lead of Goethe University. Autophagy literally means "self-eating" and refers to a sophisticated system in which cellular waste is specifically detected and removed.

UCI scientists find potential biomarker for diagnosing certain forms of autism

By identifying a key signaling defect within a specific membrane structure in all cells, University of California, Irvine researchers believe, they have found both a possible reliable biomarker for diagnosing certain forms of autism and a potential therapeutic target.

New trial results show efficacy of novel enzyme-replacement therapy for genetic lipid disorder

Of the more than 50 known lysosomal storage diseases (LSDs)-rare inherited metabolic disorders-only seven can be treated with approved enzyme-replacement therapies.
