Study helps explain why 'survival gap' persists for African-Americans A team of scientists at Johns Hopkins and in Texas has identified a handful of genetic mutations in black Americans, in addition to some chemical alterations affecting gene activity, which may help explain why the death rate among African-Americans from the most common form of head and neck cancer continues to hover some 18 percent higher above the death rate of whites with the same cancer. The so-called survival gap...

Certain genetic alterations to the PAX gene family may be responsible for survival disparities seen between African-American and non-Latino white men with head and neck cancer, according to results presented here at the Sixth AACR Conference on the Science of Cancer Health Disparities in Racial/Ethnic Minorities and the Medically Underserved, held Dec. 6-9. "During the last 30 years, the overall five-year relative survival rates for head and neck squamous cell carcinoma (HNSCC) have...

Women who are members of families with BRCA2 mutations but who test negative for the family-specific BRCA2 mutations are still at greater risk for developing breast cancer compared with women in the general population, according to a study published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research. Women with certain mutations in their BRCA1 or BRCA2 genes are at increased risk for breast cancer. However, if a woman who comes...

Findings call for a rethinking of cancer genetics Johns Hopkins researchers report that the deletion of any single gene in yeast cells puts pressure on the organism’s genome to compensate, leading to a mutation in another gene. Their discovery, which is likely applicable to human genetics because of the way DNA is conserved across species, could have significant consequences for the way genetic analysis is done in cancer and other areas of research, they say. Summarized in a report...

A new study by Weill Cornell Medical College scientists reveals a mechanism through which the expression of genes is controlled -- a finding that highlights genetic mutations that can impair the timing of gene expression. Such mutations can affect the co-ordination of key events that are required for stepwise development of an organism, and can also give rise to cancer by turning on genes at the wrong time. The study, published October 29 in the open access journal PLOS Biology, analyzes...

A gene important in skin tanning has been linked to higher risk for testicular cancer in white men, according to a study led by scientists from the U.S. National Institutes of Health and the University of Oxford in England. Nearly 80 percent of white men carry a variant form of this gene, which increased risk of testicular cancer up to threefold in the study. The research appeared online October 10, 2013 in the journal Cell, and is the result of an integrated analysis of big data supported...

Researchers announced today in the journal Lancet Oncology that they are well on the way to discovering why women with the faulty genes BRCA 1 and BRCA 2, one of which was inherited by the actress Angelina Jolie, develop breast and ovarian cancer rather than other cancers. The study, carried out by researchers at the UCL Department of Women's Cancer, found that abnormal levels of female hormones in the bloodstream could be the answer. The findings have already led to more research into...

More accurate profiles can optimize outcomes through personalized therapy. Irving, TX (PRWEB) October 16, 2013 Since July, 2013, Miraca Life Sciences (MLS) has been providing a new genomic testing protocol that helps Urologists guide better treatment decisions and determine outcomes in prostate cancer patients. MLS says two important genetic abnormalities occur in 50-60 percent of prostate cancer patients: one is characterized by loss of a protective gene known as PTEN, and another by...


Word of the Day
monteith
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
