Protein Study Opens A New Avenue For Cancer Researchers

Brigham Young University One of the hopes for victory against cancer hinges on naturally-occurring proteins whose job is to make their host cell die. Since their natural role is to stop unhealthy cell proliferation, the idea is that one or more of these proteins could be harnessed to stop the growth of tumors. Brigham Young University scientists recently stumbled onto one potential tumor suppressor with an especially ominous name: Programmed Cell Death Protein 5 (aka PDCD5). What...

In laboratory experiments conducted on human cell lines at the Johns Hopkins Kimmel Cancer Center, scientists have shown that people carrying certain mutations in two hereditary cancer genes, BRCA2 and PALB2, may have a higher than usual susceptibility to DNA damage caused by a byproduct of alcohol, called acetaldehyde. The scientists say they suspect that the two genes in their normal forms evolved to protect cells against the damaging effects of acetaldehyde, which can lead to cancer....

Genetic counseling delivered over the telephone is as effective as face-to-face counseling, finds the largest randomized study to date comparing the two methods. The multi-center study, led by researchers at Georgetown Lombardi Comprehensive Cancer Center, was reported today in the Journal of Clinical Oncology. The landscape of genetic testing has broadened to include a range of diseases, and demand for testing and counseling has greatly increased because of direct-to-consumer marketing,...

The US Supreme court ruled recently that the test patent is no longer valid causing pricing for Genetic testing to plummet. Thousand Oaks, CA (PRWEB) January 11, 2014 BRCA gene is currently the most well known breast cancer (and ovarian cancer) gene. Women with a BRCA1 and/or BRCA2 gene mutation are up to eight times more likely to develop breast malignancy than women without. In other words, the lifetime risk for getting breast cancer is up to 85%. If and when cancer happens, it tends...

A new study led by University of Kentucky researchers suggests that activating the tumor suppressor p53 in normal cells causes them to secrete Par-4, another potent tumor suppressor protein that induces cell death in cancer cells. This finding may help researchers decipher how to inhibit the growth of tumors that have become resistant to other treatments. Loss of the tumor suppressor p53 often contributes to therapy resistance in tumors. In the study, published in Cell Reports, the...

A potential new cancer therapy works by “turning on” a powerful natural tumor suppressor. Raleigh, NC (PRWEB) December 24, 2013 A new study published in Cell Cycle and reported by Surviving Mesothelioma says a molecule known by the acronym RITA (reactivation of p53 and induction of tumor cell apoptosis) may work synergistically with current cancer treatments to fight mesothelioma. RITA is one of two molecules tested in the new study, which focused on the natural tumor suppressor gene,...

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...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
