A community-based hepatitis B virus screening effort led by UC Davis researchers found that targeted outreach to Asian American populations can identify groups at high risk for infection and direct them to appropriate follow-up care to help prevent the onset of liver diseases, including cancer.
To address the deficit of interventions for older children and adolescents with fragile X, MIND Institute researcher Andrea McDuffie and colleagues created an intervention that uses a shared storytelling paradigm and real-time parent coaching, all provided in the home through telecommunications. The small but important study found that the intervention improved adolescent boys’ abilities to produce longer sentences, use more diverse vocabulary and concentrate for longer time periods during conversational interactions.
UC Davis researchers have shown that radiation therapy following surgery benefits older patients more than their younger counterparts, a surprising finding that could change the way some patients are treated for soft tissue sarcomas (STS). Also, the photo upload is not working. I'll send by email.
African American and Hispanic adolescents and young adults fare far worse than their white counterparts when faced with a mostly curable type of cancer, Hodgkin lymphoma, a study by a UC Davis epidemiologist has found
In a comprehensive modeling study, researchers from UC Davis and other institutions have found that breast cancer screening with digital mammography poses only a small risk of radiation-induced breast cancer for most women. However, the research showed increased risk for women with large breasts or breast implants, who must often receive extra screening views, increasing their radiation exposure.
A systematic review of the scientific literature on dense breasts by researchers at UC Davis and other institutions has found that determinations of breast density can be unreliable and that as many as 19 percent of women are re-categorized as dense rather than non-dense or vice versa from one mammogram to the next. The study also found that supplemental diagnostic screenings for women with dense breasts find additional breast cancers but also greatly increase false positive results.
In a game-changing study, researchers at UC Davis and other organizations have shown that the enzyme cyclin-dependent kinase 1 (CDK1), which plays a key role in DNA repair, also leaves the nucleus to boost cellular energy production. By irradiating normal cells, the team showed that CDK1 turned up production of ATP, cellular energy packets that – in this case – provided the necessary power supply to fix the radiation-damaged DNA.
Researchers at the UC Davis Comprehensive Cancer Center have shown that the microRNA, miR-124, reduced tumor growth and increased cell death in castration-resistant prostate cancer. This small RNA fragment hit multiple targets, reducing androgen receptor signaling and reviving the potency of enzalutamide, a treatment for advanced prostate cancer. In addition, miR-124 impeded EZH2 and Src, proteins that contribute to treatment resistance. The research was published online Monday in Cancer Research.
In a study conducted to inform American Cancer Society (ACS) breast cancer screening guidelines, UC Davis researcher Diana L. Miglioretti reports a screening mammogram once every two years is safe for postmenopausal women at average risk of breast cancer.
A UC Davis research team has been awarded $15.5 million to build the world’s first total-body positron emission tomography (PET) scanner, which could fundamentally change the way cancers are tracked and treated and put the university on the nation’s leading edge of molecular imaging.
A costly tool used on nearly all mammograms does not increase cancer detection rates and should no longer be covered by Medicare, argues Joshua Fenton, a family physician and comparative effectiveness researcher in an editorial published online today in the Journal of the American Medical Association Internal Medicine.
Researchers at UC Davis, in collaboration with colleagues at Jackson Laboratory, have developed a new way to personalize treatments for aggressive bladder cancer. In early proof-of-concept research, the team took bladder tumors from individual patients, identified actionable mutations and grafted the tumors into mice. From there, the researchers simultaneously tested multiple therapies in the tumor models. Treatments that were effective in the models could then be given to patients. The research was published today in the journal PLOS One.
In findings never before seen in melanoma, a novel combination therapy was found to be highly effective at treating patients with skin metastases, new research from UC Davis has shown.
Combing data collected on thousands of California ovarian cancer patients, UC Davis researchers have determined that almost one-third survived at least 10 years after diagnosis.
An international team of scientists, led by UC Davis nephrologist Robert Weiss, have used a sophisticated combination of proteomics and metabolomics to show how renal cell carcinoma (RCC) reprograms its metabolism and evades the immune system. In addition, the study found that cancer grade has a major impact on this reprogramming. These results, published online in the journal Cancer Research, point to new therapeutic options for this particularly deadly cancer.
The number of surgeries performed on terminally ill cancer patients has not dropped in recent years ¬, despite more attention to the importance of less invasive care for these patients to relieve symptoms and improve quality of life.

Two UC Davis researchers will help run a major national study to improve surveillance practices for patients with small lung nodules identified on CT imaging and extremely low risk for lung cancer.
Researchers at UC Davis have illuminated an important distinction between mice and humans: how human livers heal. The difference centers on a protein called PPARα, which activates liver regeneration. Normally, mouse PPARα is far more active and efficient than the human form, allowing mice to quickly regenerate damaged livers. However, the research shows that protein fibroblast growth factor 21 (FGF21) can boost the regenerative effects of human PPARα. The findings suggest that the molecule could offer significant therapeutic benefits for patients who have had a liver transplant or suffer from liver disease. The study was published in the journal Oncotarget.
Researchers at UC Davis have developed and characterized a molecule that interferes with the internal regulation of cancer cells, causing them to self-destruct. This novel mechanism was found to be effective against glioma cells – responsible for a usually fatal type of brain cancer – and could be applicable to other highly aggressive cancers.
Ten months after California legislators enacted a controversial law mandating that radiologists notify women if they have dense breast tissue, UC Davis researchers have found that half of primary care physicians are still unfamiliar with the law and many don’t feel comfortable answering breast density-related questions from patients. The findings, to be published in the March print edition of Journal of the American College of Radiology, suggest that if the law is going to have any significant impact on patient care, primary care providers need more education about breast density and secondary imaging options.
Scientists have long known the p53 protein suppresses tumors. However, a recent animal study by UC Davis researchers has uncovered a complicated relationship between p53 and another protein, Rbm38, highlighting how the body calibrates protein levels. Too much Rbm38 reduces p53 levels, increasing the risk of cancer. Too little Rbm38 allows p53 overexpression, causing premature aging. The study was published online in the journal PNAS Dec. 15.
Researchers at UC Davis and other institutions have found that diets rich in whole walnuts or walnut oil slowed prostate cancer growth in mice. In addition, both walnuts and walnut oil reduced cholesterol and increased insulin sensitivity. The walnut diet also reduced levels of the hormone IGF-1, which had been previously implicated in both prostate and breast cancer. The study was published online in the Journal of Medicinal Food.
Immunotherapy that can be effective against tumors in young, thin mice can be lethal to obese ones, a new study by UC Davis researchers has found. The findings, published online today in The Journal of Experimental Medicine, suggest a possible link between body fat and the risk of toxicity from some types of immunotherapy.
Researchers at UC Davis have found that the drug bortezomib effectively treats chronic graft-versus-host disease (GVHD), a common and debilitating side effect from allogeneic hematopoietic stem cell transplants. The trial showed that bortezomib provides better outcomes than existing treatments and does not impair the immune response against residual cancer cells, or the graft-versus-tumor effect (GVT).
Kit Lam and colleagues from UC Davis and other institutions have created dynamic nanoparticles (NPs) that could provide an arsenal of applications to diagnose and treat cancer. Built on an easy-to-make polymer, these particles can be used as contrast agents to light up tumors for MRI and PET scans or deliver chemo and other therapies to destroy tumors. In addition, the particles are biocompatible and have shown no toxicity. The study was published online today in Nature Communications.
Researchers at UC Davis, City of Hope, Taipai Medical University and National Health Research Institutes in Taiwan have discovered how a drug that deprives the cells of a key amino acid specifically kills cancer cells.
Researchers at UC Davis, University of Massachusetts and Harvard Medical School have created a combination drug that controls both tumor growth and metastasis. By combining a COX-2 inhibitor, similar to Celebrex, and an epoxide hydrolase (sEH) inhibitor, the drug controls angiogenesis (blood vessel formation), limiting a tumor’s ability to grow and spread. The study appears today in the journal Proceedings of the National Academy of Sciences.
Researchers at UC Davis have determined that surgical biopsies can be safely performed on select patients with late-stage non-small cell lung cancer, which should enhance their access to drugs that target specific genetic mutations such as epidermal growth factor receptor (EGFR).
Colorectal cancer screening saves lives, but too few people get tested. In an effort to increase these numbers,researchers from UC Davis and elsewhere investigated whether an individualized interactive multimedia computer program (IMCP) would spur patients to get screened. Tailored to each patient’s knowledge, language (English or Spanish), and perceptions, this sophisticated intervention increased patients’ familiarity with their options and motivation for screening. However, the program generated only a modest increase in actual screening, one no greater than the increase resulting from a simple non-tailored “electronic leaflet.” The paper was published in the Annals of Family Medicine.
An international team led by researchers at UC Davis has shown that the cyclin B1/Cdk1 protein complex, which plays a key role in cell division, also boosts the mitochondrial activity to power that process. This is the first time the complex has been shown to perform both jobs. This newfound ability could make cyclin B1/Cdk1 an excellent target to control cellular energy production, potentially advancing cancer care and regenerative medicine. The research was published online today in the journal Developmental Cell.
In an effort to reduce cancer health disparities among Asian-Americans, UC Davis Comprehensive Cancer Center now offers individual, in-language education and culturally sensitive materials for every Asian-American cancer patient.

Researchers at UC Davis have found that the investigational cancer vaccine tecemotide, when administered with the chemotherapeutic cisplatin, boosted the immune response and reduced the number of tumors in mice with lung cancer. The study also found that radiation treatments did not significantly impair the immune response. The paper was published on March 10 in the journal Cancer Immunology Research, an American Association for Cancer Research (AACR) publication.
UC Davis clinicians and physicists have recommended new strategies to make computed tomography (CT) safer, including adoption of a new metric for dose measurement, ways to manage exposure protocols that differ by CT brand and specific approaches to reduce exposure during needle biopsies. The recommendations are detailed in papers published in the March issue of the Journal of the American College of Radiology (JACR).
Twenty years after Congress mandated that research funded by the National Institutes of Health include minorities, less than 5 percent of trials participants are non-white, and less than 2 percent of clinical cancer research studies focus on non-white ethnic or racial groups, UC Davis researchers have found.
A new study involving researchers from UC Davis and four other National Cancer Institute-designated cancer centers reveals important barriers that limit minority group participation in cancer clinical trials, findings that will be used to refine and launch more effective strategies to assure that more minorities benefit from clinical trials.
The hunt is on to find biomarkers that detect cancer, but it’s a challenging process. Early successes often are followed by heartbreaking failures. But now, researchers at UC Davis have verified that glycans (sugars attached to proteins) can be used to detect ovarian cancer. The study was published online in the journal Cancer Epidemiology, Biomarkers & Prevention.
Biomarkers for bone formation and resorption predict outcomes for men with castration-resistant prostate cancer, a team of researchers from UC Davis and their collaborators have found. Their study, published online in the Journal of the National Cancer Institute, also found that the markers identified a small group of patients who responded to the investigational drug atrasentan. The markers’ predictive ability could help clinicians match treatments with individual patients, track their effectiveness and affect clinical trial design.
An international team of researchers led by UC Davis in collaboration with scientists in Mexico and South Korea have taken a first step towards identifying glycans — sugars attached to proteins — that could help clinicians diagnose gastric cancer before it becomes deadly. Their research was published in the journal Cancer Prevention Research.
With a deluge of promising new drug treatments for advanced prostate cancer on the market, a new model of care is needed that emphasizes collaboration between urologists and medical oncologists, according to UC Davis prostate cancer experts.
When public health budgets are constrained, mammography screening should begin later and occur less frequently, a cost-effectiveness analysis for California’s Every Woman Counts (EWC) program concludes.
