Discovery on how an Helicobacter pylori toxin gets into cells

Helicobacter pylori is one tough bug. It can survive in the human stomach, a zone with a pH somewhere between that of lemon juice and battery acid. Now researchers have discovered how an H. pylori toxin gets into cells, a feat that helps the bacterium live in one of the most inhospitable environments in the body

Researchers find multiple cancer genes cooperate to cause malignant cell transformation

Pinpointing new targets for cancer treatments is as difficult as finding a needle in a haystack, yet a University of Rochester team has discovered an entire novel class of genes they believe will lead to a greater understanding of cancer cell function and the next generation of effective and less harmful therapies for patients.

Common gene disorder doubles risk of lung cancer, even among nonsmokers

Mayo Clinic researchers have found that carrying a common genetic disorder doubles the risk of developing lung cancer in smokers and nonsmokers.

Americans believe wounded Iraq war veterans generally neglected

As part of the ongoing poll series, Debating Health: Election 2008, a recent survey by the Harvard Opinion Research Program at the Harvard School of Public Health (HSPH) and Harris Interactive finds that a majority of Americans (62%) believe that wounded Iraq war veterans do not receive high quality care in military and Veteran's Administration (VA) hospitals once they return to the U.S. Similar majorities feel that veterans requiring rehabilitation care and mental health care do not receive high quality care (62% and 65% respectively).

Why do some heavy drinkers develop mouth and throat cancers while others do not?

A study by researchers in Europe has revealed why some heavy drinkers develop mouth and throat cancers while others do not and also why some people get drunk quickly.

Link between HPV and cervical cancer

Scientists in the United States have carried out a review of research to determine the link between persistent HPV (human papillomavirus) infection and cervical cancer.

Higher-risk people are shunning colon cancer screens

It is difficult to make colon cancer screening effective, according to a follow-up study conducted by the Swedish medical university Karolinska Institutet of a screening programme from 1999. Many of the people who would probably have benefited most from the survey opted not to take part.

New cancer vaccine protein target found

Cancer Research UK scientists have identified an important new protein target which could be used to produce highly focused vaccine therapies for cancer - according to research published in the Journal of Clinical Investigation.

Embryonic pathway delivers stem cell traits

Studies of how cancer cells spread have led to a surprising discovery about the creation of cells with adult stem cell characteristics, offering potentially major implications for regenerative medicine and for cancer treatment.

How cells size up their growth opportunities

The intricate mechanisms that switch cell growth on and off are regulated by mammalian target of rapamycin (mTOR) protein complexes, which sense nutrients within the cell. When amino-acids are abundant, the protein complexes promote cellular growth, and when nutrients are scarce they signal that hard times are ahead to the cell. But just how nutrients regulate mTOR signaling to control size has remained a mystery. Now, scientists in the lab of Whitehead Member David Sabatini have found the first step in the process.

RTOG study likely treatment option for brain tumor patients like Sen. Kennedy

A Radiation Therapy Oncology Group (RTOG) study which seeks to establish whether high-doses of the chemotherapy drug temozolomide after radiotherapy can improve outcome for patients with newly diagnosed malignant glioma is a possible consideration for Sen. Edward Kennedy (D-Mass.) and other patients with this type of brain tumor.

Discovery provides hope for patients with pancreatic cancer

This week researchers in the Oregon Health & Science University (OHSU) Oregon Stem Cell Center and the OHSU Digestive Health Center are shining a new ray of hope on patients with pancreatic cancer. They've developed new reagents, or antibodies, that can recognize this often lethal disease. This important discovery may one day lead to earlier detection and treatment.

Experimental drug blocks prostate cancer in animal study

An experimental drug has blocked the progression of prostate cancer in an animal model with an aggressive form of the disease, new research shows.

Smoke-free laws are protecting all workers according to new study

A new study published today by the U.S. Centers for Disease Control and Prevention underscores the powerful momentum across the country to pass strong smoke-free workplace laws that protect all workers and the public from the serious health hazards of secondhand smoke.

Study finds increased risk of some cancers among HIV-positive people in U.S.

HIV-positive people in the U.S., many of whom are living longer because of antiretroviral drugs, are at an increased risk for certain types of cancers, according to a study published Tuesday in the Annals of Internal Medicine, Reuters reports.

Research shows protecting p53 from degradation also defends metastasis-promoter

Efforts to protect the tumor-suppressor p53 could just as easily shelter a mutant version of the protein, causing cancer cells to thrive and spread rather than die, according to research by scientists at The University of Texas M. D. Anderson Cancer Center reported in the current issue of the journal Genes and Development.

Simple blood test could indicate higher risk for coronary events in women after post-menopausal hormone therapies

A research study has found that a simple blood test may indicate whether post-menopausal hormone therapies present an elevated risk of a heart attack.

NCI scientists visualize gene regulation in living cells

A research team led by scientists at the National Cancer Institute (NCI), part of the National Institutes of Health (NIH), has applied advanced imaging methods and computer simulations to be able to glance at the regulation of a cancer-related gene in a living cell. They found that the efficiency with which the components of the cell's gene reading machinery come together has an impact on gene expression, the process by which a gene translates its information into a new protein. The findings, published in the May 23, 2008 issue of Molecular Cell, shed new light on the means by which living cells regulate gene activity.

High resolution confocal endomicroscopy probe system tells whether colon polyp is benign without removal

A probe so sensitive that it can tell whether or not a cell living within the human body is veering towards cancer development may revolutionize how future colonoscopies are done, say researchers from the Mayo Clinic in Jacksonville, Fla.
