Researchers have designed a urine test that can simultaneously measure the extent of a potential carcinogenic process and a marker of garlic consumption in humans. In a small pilot study, the test suggested that the more garlic people consumed, the lower the levels of the potential carcinogenic process were. The research is all about body processes associated with nitrogen-containing compounds, scientists say. These processes include nitrosation, or the conversion of some substances found in...

PHILADELPHIA "” Researchers have found a new oncogenic signaling pathway by which the environmental toxin arsenic may lead to adverse health effects, including bladder cancer. These study results are published in Cancer Research, a journal of the American Association for Cancer Research. "In a collaborative investigation we found that arsenic, at environmentally relevant levels, is capable of activating the Hedgehog pathway and may represent a novel pathway of arsenic-associated...

A team of researchers, led by Yi-Ching Wang, at National Cheng Kung University, Taiwan, Republic of China, has uncovered a potential mechanism by which the tobacco-specific carcinogen NNK promotes lung tumor formation and development. Specifically, they suggest that NNK induces the accumulation of a protein known as DNMT1 in the nucleus and that this protein silences genes that suppress tumor formation. The authors generate several lines of evidence to support their suggested mechanism, one...

Repeated exposure to tobacco smoke makes lung cancer much worse, and one reason is that it steps up inflammation in the lung. Scientists at the University of California, San Diego School of Medicine have found that mice with early lung cancer lesions that were repeatedly exposed to tobacco smoke developed larger tumors "“ and developed tumors more quickly "“ than unexposed animals. The key contributing factor was lung tissue inflammation. The results of their study, to be...

A new study on the smokeless tobacco product called moist snuff "” placed between lip and gum "” has led scientists in Minnesota to urge the tobacco industry to change manufacturing practices to reduce snuff's content of carcinogens. Their study is published online in ACS' monthly journal Chemical Research in Toxicology. It reports that this category of tobacco products contains surprisingly high levels of certain toxic and cancer-causing substances. Called polycyclic aromatic...
