Calibrating Lactoferrin Protein in Milk may Boost Learning and Protect Neurons

Frederic Troy, Ph.D.

Diets with different concentrations of lactoferrin (Lf), a protein found naturally in human and cow milk, have significantly different impacts on brain development and neuroprotection, a new study co-led by Professor Frederic A. Troy II has found.

“Our studies revealed an unexpected and rather paradoxical finding,” Troy said.

The study, published in the journal Molecular Nutrition and Food Research, showed that lower Lf levels were linked to better neurodevelopment and learning. Higher levels were strongly correlated with the protection of neurons and possibly the prevention of neurological-associated disorders.

A new target for triple-negative breast cancer?

Hongwu Chen, Ph.D.Early-stage breast cancer can be curable, but one type presents major treatment challenges: triple-negative breast cancer (TNBC). “Triple negative” means these tumors lack the receptors for estrogen, progesterone and HER2, so TNBC patients don’t have access to important targeted therapies, such as Herceptin or Tamoxifen.

“TNBC is actually many different kinds of cancer,” says Hongwu Chen, professor in the Department of Biochemistry and Molecular Medicine and a Cancer Center researcher. “Some of them are very aggressive and are more likely to relapse after treatment.”

In a study published in Cell Reports, Wenbin Deng and his colleagues present data showing that immature astroglial transplants, derived from human-induced pluripotent stem cells (iPSCs), are highly protective against white matter brain injury – which can occur from lack of oxygen following a stroke or in childbirth – and can improve spatial learning and memory function in mouse models.


New target makes end run against therapy-resistant prostate cancer

Wang_ChenResearchers at UC Davis, in collaboration with the other institutions, have found that suppressing the nuclear receptor protein ROR-γ with small-molecule compounds can reduce androgen receptor (AR) levels in castration-resistant prostate cancer and stop tumor growth.

This novel approach does not directly target the AR, but rather inhibits the gene that codes for the AR protein. Reducing AR levels could help patients overcome treatment-resistant prostate cancer and even rescue existing therapies. The research was published today in the prestigious journal Nature Medicine.

Tumor suppressor LRIG1 controls breast cancer aggression and invasion

Colleen Sweeney, Ph.D.Researchers at UC Davis have shown that the protein LRIG1 reduces breast cancer invasion and could potentially help control metastasis. Using aggressive basal-like breast cancer cell lines, the scientists found that restoring LRIG1 expression reduced these cells’ growth and invasiveness. The findings provide strong evidence that LRIG1 could be exploited therapeutically to block metastasis. The research was published online today in the journal Oncogene.

“The loss of LRIG1 has been linked to poor clinical outcomes in a number of cancers,” said Colleen Sweeney, senior author, professor and director of the Breast Cancer Research Program at the UC Davis Comprehensive Cancer Center. “On the other hand, patients whose breast cancers have retained LRIG1 expression demonstrate longer metastasis-free survival. Now, for the first time, we have shown in the lab that LRIG1 has metastasis-suppressing properties.”

UC Davis researchers find promising new treatment approach for ischemic stroke

Deng teamA team of UC Davis scientists has found that administering a small molecule – purmorphamine – in animal models after a stroke results in multiple protective effects, including reducing the size of the stroke, decreasing inflammation and increasing markers for nerve regeneration. The findings, which may offer a new approach to treating ischemic stroke — the disruption of blood flow in the brain from a blood clot — are published online in the journal Cell Death and Disease.

“We have revealed a previously unrecognized role of a developmental pathway that, when stimulated with a small molecule drug, leads to neuroprotection, regeneration and functional recovery following ischemic stroke,” said Wenbin Deng, associate professor in the UC Davis Department of Biochemistry and Molecular Medicine, and principal investigator of the study. “This is an important conceptual advance that could lead to a novel treatment approach, paving the way for new medicines in the treatment of a variety of neurological and neurodegenerative diseases."

'Support cells' in brain play important role in Down syndrome

Deng Pleasure GroupResearchers from UC Davis School of Medicine and Shriners Hospitals for Children – Northern California have identified a group of cells in the brain that they say plays an important role in the abnormal neuron development in Down syndrome. After developing a new model for studying the syndrome using patient-derived stem cells, the scientists also found that applying an inexpensive antibiotic to the cells appears to correct many abnormalities in the interaction between the cells and developing neurons.

“We have developed a human cellular model for studying brain development in Down syndrome that allows us to carry out detailed physiological studies and screen possible new therapies,” said Wenbin Deng, associate professor of biochemistry and molecular medicine and principal investigator of the study. “This model is more realistic than traditional animal models because it is derived from a patient’s own cells.”

Neural stem cell discovery may aid in treatment research for deafness

Frederic Troy, Ph.D.Researchers at UC Davis School of Medicine have for the first time shown that a polysialylated glycoprotein that regulates neurodevelopment exists on the surface of cells in the adult inner ear. This biomarker of early cells allows researchers to identify immature cells so that they can be used for further research and possible treatment. The discovery, published online in the journal Biochemical and Biophysical Research Communications, opens the door to developing stem cell replacement treatments in the inner ear to treat certain hearing disorders.

“Hearing loss is a complex process and is usually regarded as irreversible,” said Frederic A. Troy II, principal investigator of the study and professor emeritus of biochemistry and molecular medicine, and a member of the UC Davis Comprehensive Cancer Center. “Finding this molecule in the inner ear that is known to be associated with early development may change that view.”

A new weapon against stroke

Deng researchersOne of regenerative medicine’s greatest goals is to develop new treatments for stroke. So far, stem cell research for the disease has focused on developing therapeutic neurons — the primary movers of electrical impulses in the brain — to repair tissue damaged when oxygen to the brain is limited by a blood clot or break in a vessel. New UC Davis research, however, shows that other cells may be better suited for the task.

“Astrocytes are often considered just ‘housekeeping’ cells because of their supportive roles to neurons, but they’re actually much more sophisticated,” said Wenbin Deng, associate professor of biochemistry and molecular medicine at UC Davis and senior author of the study. “They are critical to several brain functions and are believed to protect neurons from injury and death. They are not excitable cells like neurons and are easier to harness. We wanted to explore their potential in treating neurological disorders, beginning with stroke.”

UC Davis researchers create molecule that blocks pathway leading to Alzheimer's disease

John Voss and TeamUC Davis researchers have found novel compounds that disrupt the formation of amyloid, the clumps of protein in the brains of people with Alzheimer's disease believed to be important in causing the disease's characteristic mental decline. The so-called "spin-labeled fluorene compounds" are an important new target for researchers and physicians focused on diagnosing, treating and studying the disease.

The study, published today in the online journal PLoS ONE, is entitled "The influence of spin-labeled fluorene compounds on the assembly and toxicity of the Aβ peptide."

"We have found these small molecules to have significant beneficial effects on cultured neurons, from protecting against toxic compounds that form in neurons to reducing inflammatory factors," said John C. Voss, professor of biochemistry and molecular medicine at the UC Davis School of Medicine and the principal investigator of the study. "As a result, they have great potential as a therapeutic agent to prevent or delay injury in individuals in the earliest stages of Alzheimer's disease, before significant damage to the brain occurs."

UC Davis researchers solve multiple sclerosis brain-cell mystery

Chengji Zhou, Ph.D.Researchers at UC Davis that included Professor Chengji Zhou, have discovered the source of cells involved in a phenomenon called reactive astrogliosis, characterized by a large number of enlarged star-shaped cells in the brains and spinal cords of people with multiple sclerosis (MS), Alzheimer's disease and multiple episodes of minor head trauma. In multiple sclerosis, these abnormal cells are found in plaques that damage the myelin sheath that surrounds neurons, impairing their signaling function.

The study is led by David Pleasure, director of UC Davis' Institute for Pediatric Regenerative Medicine, and offers the first firm evidence to date that, at least in the case of multiple sclerosis, the cells are descendant from normal astrocytes.

UC Davis researchers find molecule that targets brain tumors

Kit S. Lam, M.D., Ph.D.UC Davis Cancer Center researchers report today the discovery of a molecule that targets glioblastoma, a highly deadly form of cancer. The finding, which is published in the January 2009 issue of the European Journal of Nuclear Medicine and Molecular Imaging, provides hope for effectively treating an incurable cancer.

Glioblastoma is the most common and aggressive type of primary brain tumor in adults. It is marked by tumors with irregular shapes and poorly defined borders that rapidly invade neighboring tissues, making them difficult to remove surgically.

"These brain tumors are currently treated with surgery to remove as much of the tumor as possible followed by radiation to kill cancer cells left behind and systemic chemotherapy to prevent spread to nearby tissues," said Kit Lam, senior author of the study and UC Davis chief of hematology and oncology. "It is unfortunate that this approach does not extend survival significantly. Most patients survive less than one year."

UC Davis researchers discover a key to aggressive breast cancer

Colleen Sweeney, Ph.D.In trying to find out why HER2-positive breast cancer can be more aggressive than other forms of the disease, UC Davis Cancer Center researchers have surprisingly discovered that HER2 itself is the culprit. By shutting down its own regulator gene, HER2 creates a permissive environment for tumor growth.

Building on recent research showing that the regulator — labeled LRIG1 and commonly called "Lig-1" — limits the growth-promoting signals of HER2, the research team set out to clarify the role of Lig-1 in breast cancer.

They found that, when compared to healthy breast tissue, the regulator is significantly suppressed.

"This suppression assists HER2 in its own over-expression and in driving the growth of cancer cells," said Colleen Sweeney, associate professor of biochemistry and molecular medicine and senior author of the study, which appears in this month's issue of Cancer Research. "HER2 is clearly taking an active role its own ability to be successful in promoting cancer."

The five-year grant is the largest funding award in history to focus on this or any other fragile X-related disorder.

Led by molecular geneticist Paul Hagerman, the institute is one of nine interdisciplinary research consortia announced today by the NIH Roadmap for Medical Research. The roadmap's goal is to integrate different disciplines to address health challenges that have been resistant to traditional research approaches. Funding the consortia represents a fundamental change in both the culture within which biomedical and behavioral research is conducted and the culture within the NIH, where research projects are normally managed by an individual institute or center.


Assessing the impact of ancestry genes on women's health

Seldin TeamUC Davis researchers are conducting a first-of-its-kind genetic study to determine the importance of ancestry on the development of diseases in women. The research is a follow up to the landmark Women's Health Initiative study, which assessed the long-term benefits of common treatments for preventing heart disease, breast and colorectal cancer and osteoporosis fractures — the most frequent causes of death and poor quality of life in postmenopausal women.

"This research allows us to identify additional genes that are important in causing diseases that disproportionately affect women or affect them in different ways than men," explained Professor Michael Seldin, principal investigator and chair of the Rowe Program in Human Genetics at UC Davis.

UC Davis study finds distinct genetic profiles for northern, southern Europeans

Michael F. Seldin, M.D., Ph.D.An international team of scientists led by researchers at UC Davis Health has found that, with respect to genetics, modern Europeans fall into two groups: A Northern group and a Southern, or Mediterranean one. The findings, published in the Sept. 14 edition of Public Library of Science Genetics, are important because they provide a method for scientists to take into account European ancestry when looking for genes involved in diseases. "Until now, little has been known about the distribution of genetic variation in European populations and how much that distribution matters in terms of doing genetic studies," said Michael Seldin, chair of the Rowe Program in Genetics at UC Davis Health System. "Now we will be able to control for these differences in European populations in our efforts to find genes that cause common diseases." Seldin, who is also a professor of biochemistry and professor of medicine at UC Davis, worked with his colleagues to compare genetic data for 928 individuals.
