Does the desire to consume alcohol and tobacco come from our genetic makeup?

In an attempt to find the genomic determinants underlying alcohol and tobacco use, researchers examined 120 families (approximately 900 individuals). The researchers identified an area relating to alcohol and tobacco use on chromosome 1. They found another area relating to alcohol on chromosome 3. On chromosome 4, they uncovered an area relating to smoking and found sex-specific loci inside some of these areas.

2. Animals Resistant To Drunken Behavior Offer Clues To Alcoholism's Roots
   10-06-2006 · ScienceDaily
   Animals with a remarkable ability to hold their liquor may point the way toward the genetic underpinnings of alcohol addiction, two separate research teams reported in the October 6, 2006 issue of the journal Cell. Earlier studies have shown that people with a greater tolerance for alcohol have a greater risk of becoming alcoholics, according to the researchers.

3. Tobacco and alcohol use independently increase risk of head and neck cancer
   05-15-2007 · EurekAlert!
   Cigarette smoking is more strongly associated with head and neck cancers than drinking alcohol, according to a study in the May 16 issue of the Journal of the National Cancer Institute. The study found that smoking is responsible for a quarter of head and neck cancers among individuals who do not drink alcohol.

4. Mathematics reveals genetic pattern of tumor growth
   06-21-2007 · EurekAlert!
   Using mathematical theory, UC Irvine scientists have shed light on one of cancer's most troubling puzzles -- how cancer cells can alter their own genetic makeup to accelerate tumor growth. The discovery shows for the first time why this change occurs, providing insight into how cancerous tumors thrive and a potential foundation for future cancer treatments.

   12-18-2007 · EurekAlert!
   The research reveals that a subject's brain with low beta-endorphin levels becomes accustomed to the presence of an exogenous surplus, diminishing its own supply and triggering dependence on an external source -- in this case, alcohol.

   04-16-2007 · EurekAlert!
   A team of researchers, including an economist from Arizona State University, have studied the growth of cities in different parts of the world and have come up with general equations that can foretell their consumption of resources and their contributions to society. The work has debunked the notion that cities act like biological organisms, that once they start they grow, and consume and contribute at predictable linear rates.

   The time has come for breast cancer risk assessment, counseling and genetic testing to move from cancer specialists to the realm of primary care. A growing body of evidence has documented the benefits of preventive measures for high-risk women including those with mutations in the BRCA1 and BRCA2 genes. Referral for cancer-risk assessment and BRCA testing in the primary care setting is a necessary step towards personalized medicine for women at risk.

   10-19-2006 · EurekAlert!
   Fruit flies get "drunk," just like humans, when exposed to large amounts of alcohol and may in future help to explain why some people are genetically predisposed to alcohol abuse. Humans and fruit flies respond to alcohol in a very similar way at the gene level, according to a study published today in the open access journal Genome Biology.

9. Genetic hearing loss may be reversible without gene therapy
   02-22-2007 · EurekAlert!
   A large proportion of genetically caused deafness in humans may be reversible by compensating for a missing protein. Researchers have found that in mice, increasing the amount of the protein connexin26 in the ear's cochlea compensates for an absence of another protein, connexin30. The findings come 10 years after scientists first discovered that connexin26 mutations cause much of the deafness diagnosed at birth.

10. Breakthrough in understanding type-2 diabetes as key genes identified
    02-14-2007 · EurekAlert!
    The most important genes associated with a risk of developing type-2 diabetes have been identified, scientists report today in a new study. The research, published online in Nature, is the first time the genetic makeup of any disease has been mapped in such detail. It should enable scientists to develop a genetic test to show an individual their likelihood of developing diabetes mellitus type 2, commonly known as type-2 diabetes.
