Smoking plays a role in lung cancer development, and now scientists have shown that smoking also affects the way genes are expressed, leading to alterations in cell division and regulation of immune response. Notably, some of the changes in gene expression persisted in people who had quit smoking many years earlier. These findings by researchers at the National Cancer … [Read more...] about Smoking’s Effects on Genes May Play a Role in Lung Cancer Development and Survival

Individual brain chemistry and genes could be key to understanding why some people become addicted to nicotine and why the chemical compound's effects appear to diminish at night, University of Colorado at Boulder researchers say. "The depth of a person's addiction to nicotine appears to depend on his or her unique internal chemistry and genetic make-up," said lead author … [Read more...] about Corticosterone, Genetics And The Addiction Of Nicotine
Smoking Research Studies Exposure to Cigarette Smoke Researchers at the University of Pennsylvania recently received a $2.3 million grant from the National Institutes of Health for a new study focusing on the chemical changes that occur when the body is exposed to cigarette smoke. Previous research has shown that chemical changes in the body can occur after exposure to … [Read more...] about NIH to Fund New Research Study Regarding Exposure to Cigarette Smoke
Researchers Say It Takes Genes, Viruses and Cigarettes Physicians say that smoking is by far the biggest cause of emphysema, but why doesn't every smoker get the disease? If you asked Michael Holtzman, M.D., that question, he might answer that for most cases of emphysema you need a mix of genes, viruses and cigarettes. Emphysema and the associated condition of chronic … [Read more...] about Why Doesn’t Every Smoker Get Emphysema?
