Another role for protein Mer in novel, targeted cancer treatments

Since the mid-1990s, doctors have had the protein Mer in their sights - it coats the outside of cancer cells, transmitting signals inside the cells that aid their uncontrolled growth.

Modified Citrus Pectin binds and blocks harmful effects of Galectin-3

Galectin-3 sounds like a planet out of "Star Trek," but it can be much more ominous. Recently, distinguished integrative physician Isaac Eliaz, M.D., presented breakthrough research demonstrating that the protein Galectin-3 is an active biomarker for numerous life-threatening diseases. Even more importantly, Dr. Eliaz showed how Modified Citrus Pectin (MCP) binds and blocks Galectin-3 throughout the body.

Scientists track genetic pathway of prostate cancer in new approach to drug discovery

Tracking the genetic pathway of a disease offers a powerful, new approach to drug discovery, according to scientists at the University of California, San Diego School of Medicine who used the approach to uncover a potential treatment for prostate cancer, using a drug currently marketed for congestive heart failure. Their findings are published in the current online issue of the Proceedings of the National Academy of Sciences.

Researchers crack problem of predicting gene targets for PcG proteins

Cancer is usually attributed to faulty genes, but growing evidence from the field of cancer epigenetics indicates a key role for the gene "silencing" proteins that stably turn genes off inside the cell nucleus. A new study from Rice University and Baylor College of Medicine promises to speed research in the field by rapidly identifying the genes that epigenetic proteins can target for silencing.

Inovio achieves strong T cell immune responses in PENNVAX-B Phase I HIV study

Inovio Pharmaceuticals, Inc. announced today that it has achieved strong T cell immune responses in a Phase I clinical study of PENNVAX-B, its product for the treatment of the HIV subtype prevalent in North America and Europe, in HIV-positive subjects.

EBV can infect and may also contribute to lymphomas in man's best friend

More than 90 percent of humans have antibodies to the Epstein Barr virus. Best known for causing mononucleosis, or "the kissing disease," the virus has also been implicated in more serious conditions, including Hodgkin's, non-Hodgkin's and Burkitt's lymphomas. Yet little is known about exactly how EBV triggers these diseases.

Researchers discover over 500 genes that may contribute to pancreatic cancer

A global team led by scientists from The Methodist Hospital Research Institute has identified more than 500 genes that may cause or contribute to the development of pancreatic cancer.

New work describes communities of active bacteria harbored by honey bee colonies

A novel study of honey bee genetic diversity co-authored by an Indiana University biologist has for the first time found that greater diversity in worker bees leads to colonies with fewer pathogens and more abundant helpful bacteria like probiotic species.

Binge drinking linked to brain damage in teens and young adults

Every year, thousands of teens and young adults celebrate Spring Break by drinking large amounts of alcohol — binge drinking — a dangerous right-of-passage for some and one linked to possible brain damage later as adults, says an expert.

Trudeau Institute creates TICRO to expand the scope of biomedical research

The Trudeau Institute announced today that it has expanded the scope of its biomedical research by creating a contract research organization (CRO), the Trudeau Institute Contract Research Organization.

FTY720 improves locomotor recovery in mice with SCI

A new study suggests that administering FTY720, an oral drug that has shown promise in trials for human multiple sclerosis, significantly improves locomotor recovery in mice with spinal cord injury.

Scientists at Seattle conference discuss progress, obstacles in fight against HIV/AIDS

"Scientists, stymied for decades by the complexity of the human immunodeficiency virus, are making progress on several fronts in the search for a cure for HIV infections," but "a major stumbling block is the fact that HIV lies low in pools or reservoirs of latent infection that even powerful drugs cannot reach, scientists told the Conference on Retroviruses and Opportunistic Infections, one of the world's largest scientific meetings on HIV/AIDS," in Seattle last week, Reuters reports.

JAK-STAT inhibitors reverse MS-like disease in mice

A new class of drugs completing clinical trials soon for rheumatoid arthritis should be examined as a treatment for multiple sclerosis, according to the authors of a University of Alabama at Birmingham study published today in the Proceedings of the National Academy of Sciences.

RhoGDI2 protein helps prevent bladder cancer metastasis to the lungs

The diagnosis of localized bladder cancer carries an 80 percent five-year survival rate, but once the cancer spreads, the survival rate at even three years is only 20 percent. A major study published today in the Journal of Clinical Investigation not only shows how bladder cancer metastasizes to the lungs but pinpoints a method for stopping this spread.

Parental exposure to solvents may increase risk of ASD in children

Could parental exposure to solvents at work be linked to autism spectrum disorder (ASD) in their children? According to an exploratory study by Erin McCanlies, a research epidemiologist from the National Institute for Occupational Safety and Health (NIOSH), and colleagues, such exposures could play a role, but more research would be needed to confirm an association.

Researchers elucidate function of Codanin-1 protein

Within all our cells lies two meters of DNA, highly ordered in a structure of less than 10 micro meters in diameter. Special proteins called histones act as small building bricks, organising our DNA in this structure. Preservation of the structure is necessary to maintain correct function of our genes, making histones detrimental for maintaining a healthy and functional body.

Study addresses how human body controls gamma-herpesviruses

New research from the Trudeau Institute addresses how the human body controls gamma-herpesviruses, a class of viruses thought to cause a variety of cancers. The study, carried out in the laboratory of Dr. Marcia Blackman, awaits publication in The Journal of Immunology.

Liver sinusoidal endothelial cells can promote liver regeneration

The liver is unique among mammalian organs in its ability to regenerate after significant tissue damage or even partial surgical removal. Laurie DeLeve and her colleagues at the University of Southern California in Los Angeles wanted to better understand which cells are specifically responsible for driving liver regeneration.
