Researchers Illuminate Key Role of NOX Proteins in Liver Disease

Study adds credence to new treatment approach now in clinical trials —

Researchers at the University of California, San Diego School of Medicine have demonstrated a direct connection between two signaling proteins and liver fibrosis, a scarring process underlying chronic liver disease, the 12th leading cause of death in the United States.

The finding adds further credence to a current pharmaceutical effort to create new treatments for diabetic nephropathy, liver fibrosis and other progressive fibrotic and inflammatory diseases, based on blocking these two molecules, both members of the NADPH (nicotinamide adenine dinucleotide phosphate) oxidase (NOX) family of proteins. … Read the Full Story from the UC San Diego News Center

New Drug Combination Treats Hepatitis C Patients Also Infected with HIV

Novel treatment has 97 percent success rate in co-infected patients —

Roughly 20 to 30 percent of patients with hepatitis C virus (HCV) are also infected with human immunodeficiency virus type 1 (HIV). Both blood-borne viruses share the same modes of transmission, but many HCV medications currently have significant limitations due to adverse interactions with HIV treatments. Researchers at University of California, San Diego School of Medicine report a new combination that effectively treats HCV in patients co-infected with HIV. … Read the full story from the UC San Diego News Center

Nanospheres Safely Deliver High Chemotherapy Doses in Response to Tumor Secretions

Scientists have designed nanoparticles that release drugs in the presence of a class of proteins that enable cancers to metastasize. That is, they have engineered a drug delivery system so that the very enzymes that make cancers dangerous could instead guide their destruction.

“We can start with a small molecule and build that into a nanoscale carrier that can seek out a tumor and deliver a payload of drug,” said Cassandra Callmann, a graduate student in chemistry and biochemistry at the University of California, San Diego, and first author of the report published in the journal Advanced Materials July 14. …Read the full story from the UC San Diego News Center

Protein’s Impact on Colorectal Cancer is Dappled

In early stages, it acts as tumor suppressor; later it can help spread disease —

Researchers at University of California, San Diego School of Medicine have discovered a cell signaling pathway that appears to exert some control over initiation and progression of colorectal cancer, the third leading cause of cancer-related death in the United States. A key protein in the pathway also appears to be predictive of cancer survival rates. … Read the full story from the UC San Diego Newsroom

New Biomarkers Might Help Personalize Metastatic Colorectal Cancer Treatment

Low levels of two genes predicts positive response to chemotherapy and longer survival times —

Metastatic colorectal cancer patients tend to live longer when they respond to the first line of chemotherapy their doctors recommend. To better predict how patients will respond to chemotherapy drugs before they begin treatment, researchers at University of California, San Diego School of Medicine conducted a proof-of-principle study with a small group of metastatic colorectal cancer patients. The results, published June 17 in PLOS ONE, revealed two genes that could help physicians make more informed treatment decisions for patients with this disease. …Read the full story from the UC San Diego Newsroom

Clinical Trial Launched to Assess Safety and Efficacy of Autism Drug Treatment

UC San Diego researchers open first study of suramin in children with autism —

Researchers at the University of California, San Diego School of Medicine have launched a clinical trial to investigate the safety and efficacy of an unprecedented drug therapy for autism.

The phase 1 clinical trial, which is recruiting 20 qualifying participants, will evaluate suramin – a century-old drug still used for African sleeping sickness – as a novel treatment for children with a diagnosis of Autism Spectrum Disorder (ASD). Previous published research by Robert K. Naviaux, MD, PhD, professor of medicine, pediatrics and pathology at UC San Diego School of Medicine, and colleagues reported that a single injection of suramin reversed symptoms of ASD in mouse models. …Read the full story from the UC San Diego Newsroom

Researchers Boost Body’s Inflammation-Reduction Mechanism to Combat Obesity-Fueled Disease

Researchers at University of California, San Diego School of Medicine and University College Dublin (UCD) have found that augmenting a naturally occurring molecule in the body can help protect against obesity-related diseases by reducing inflammation in the fat tissues. The study, published June 4 in the journal Cell Metabolism, focused on liver and kidney diseases, but the researchers believe it could lead to a new therapeutic approach for a variety of obesity-fueled conditions.

“This is a new way of reducing inflammation and protecting organs, using a compound that’s already produced by the body,” said co-senior author Kumar Sharma, MD, a professor of medicine and director of the Center for Renal Translational Medicine at UC San Diego School of Medicine. “Essentially, we’re boosting the body’s natural response for reducing inflammation and showing the benefit in obesity-driven diseases.” … Read the full story from the UC San Diego Newsroom
