In recent years, researchers have identified specific gene mutations linked to gastrointestinal stromal tumors (GIST), which primarily occur in the stomach or small intestine, with 5,000 to 6,000 new cases per year in the United States.
But 10 to 15 percent of adult GIST cases and most pediatric cases lack the documented tell-tale mutations, making identification and treatment more difficult. In their paper published online Dec. 14 in the Journal of Translational Medicine, researchers at University of California San Diego School of Medicine and Moores Cancer Center have identified new gene fusions and mutations associated with this subset of GIST patients. … Read the Full Story from the UC San Diego Newsroom

Overturning previous assumptions, study also provides new, more realistic model for liver cancer research and drug development —
Some cancers are caused by loss of enzymes that should keep cell growth in check. On the flip side, some are caused by over-activation of enzymes that enhance cell growth. Yet drugs that inhibit the overactive enzymes have failed to work against liver cancer. In mouse models, researchers at University of California San Diego School of Medicine have discovered a potential reason — counterintuitively, lack of both types of these enzymes can lead to liver disease and cancer. In human liver tumor samples, they also found that deficiencies in these two enzymes, called Shp2 and Pten, are associated with poor prognosis.
The study team includes Rohit Loomba, MD, MHSc, Director of the NAFLD Research Center and Director of Hepatology in the Division of Gastroenterology, Department of Medicine at UC San Diego. Dr. Loomba is Professor of Medicine (with tenure) and Vice Chief, Division of Gastroenterology.
Dr. Loomba is also Adjunct Professor, Division of Epidemiology, Department of Family Medicine and Public Health.
The innovation ecosystem at UC San Diego will open more opportunities for campus entrepreneurs with the launch of Accelerating Innovations to Market (AIM), an ambitious program that encourages graduate students, postdoctoral scholars, researchers and faculty to develop and commercialize their problem-solving ideas.
Coordinated by the Office of Innovation and Commercialization (OIC), the program invests in milestone-based projects that develop proofs-of-concept and reduce the risk of early-stage technologies. According to Paul Roben, Associate Vice Chancellor for Innovation, a central focus of AIM is value-driven engagement with industry. … Read the Full Story from the UC San Diego Newsroom
New class teaches undergrads to use engineering-based solutions to bridge gap between engineering and medicine —
A group of UC San Diego bioengineering students huddle around a computer screen as colored images of blood being pumped through a heart flash across the screen. The students are observing as a physician annotates an MRI of a patient’s heart and recommend treatment.
Previous studies identified the Hippo pathway kinases LATS1/2 as a tumor suppressor, but new research led by University of California San Diego School of Medicine scientists reveals a surprising role for these enzymes in subduing cancer immunity. The findings, published in Cell on December 1, could have a clinical role in improving efficiency of immunotherapy drugs. … Read the Full Story from the UC San Diego Newsroom
Researchers at University of California San Diego School of Medicine have identified a previously unknown mechanism that helps fortify the structure and tight junctions between epithelial cells — a basic cell type that lines various body cavities and organs throughout the body, forming a protective barrier against toxins, pathogens and inflammatory triggers. Breaches of this barrier can provoke organ dysfunction and development of tumors.

A new bioinformatic framework developed by researchers at University of California San Diego School of Medicine has identified key proteins significantly altered at the gene-expression level in biopsied tissue from patients with diabetic kidney disease, a result that may reveal new therapeutic targets. … Read the Full Story from the UC San Diego Newsroom
Researchers at University of California San Diego School of Medicine have shown that ustekinumab, a human antibody used to treat arthritis, significantly induces response and remission in patients with moderate to severe Crohn’s disease. Results of the clinical trial will appear in the November 16 issue of the New England Journal of Medicine.
“A high percentage of the patients in the study who had not responded to conventional therapies were in clinical remission after only a single dose of intravenous ustekinumab,” said William J. Sandborn, MD, professor of medicine at UC San Diego School of Medicine and director of the Inflammatory Bowel Disease Center at UC San Diego Health. … Read the Full Story from the UC San Diego Newsroom
By removing the protein galectin-3 (Gal3), a team of investigators led by University of California School of Medicine researchers were able to reverse diabetic insulin resistance and glucose intolerance in mouse models of obesity and diabetes. … Read the Full Story from the UC San Diego Newsroom
In mouse models and patient cells, anti-CD98 antibody disrupts interactions between leukemia cells and surrounding blood vessels, inhibiting cancer’s growth —
Acute myeloid leukemia (AML) is an aggressive cancer known for drug resistance and relapse. In an effort to uncover new treatment strategies, researchers at University of California San Diego School of Medicine and Moores Cancer Center discovered that a cell surface molecule known as CD98 promotes AML. … Read the Full Story from the UC San Diego Newsroom
