Berkeley Lab Confirms Thirdhand Smoke Causes DNA Damage

A study led by researchers from Lawrence Berkeley National Laboratory has found for the first time that thirdhand smoke - the noxious residue that clings to virtually all surfaces long after the secondhand smoke from a cigarette has cleared out - causes significant genetic damage in human cells.

Furthermore, the study also found that chronic exposure is worse than acute exposure, with the chemical compounds in samples exposed to chronic thirdhand smoke existing in higher concentrations and causing more DNA damage than samples exposed to acute thirdhand smoke, suggesting that the residue becomes more harmful over time...


Scientists think they have discovered why cancer spreads from one part of the  body to another, and say it will be "relatively easy" to stop the process. Experiments carried out by a team at University College London uncovered what  causes the disease to migrate.

In many cases, death from cancer is not caused by the primary tumour, but the  secondary growth. Scientists found that diseased cells are attracted to healthy cells, which then  try to move away from the cancerous cell. However, the cancer cell continues to  follow the healthy cell, causing the disease to spread through the body.

Research Reveals Cell-Free DNA Accurately Correlates with Breast Cancer DNA

A recent pilot study done at Chronix Biomedical and The University of Texas MD Anderson Cancer Center has revealed that breast cancer patients can be monitored for cell-free DNA (cfDNA) in their blood samples.  This group of researchers has demonstrated that these samples accurately correlate with breast cancer.

As the world’s population lives longer than ever, if we don’t succumb to heart disease, strokes or accidents, it is more likely that cancer will get us one way or another. Cancer is tough to fight, as the body learns how to outsmart medical approaches that often kill normal cells while targeting the malignant ones.


Here are the 10 warning signs of cancer brought to you by The VCC and The Lehigh Valley Dream Weavers Agility Club (LVDWAC) which is dedicated to the growing sport of dog agility. Club membership is open to any and all dog breeds, including mixed breeds, who enjoy participating in agility, both competitively and non-competitively. Read more....


Analysis identifies 37 RNA molecules that might predict survival in breast cancer patients

A Big Data analysis that integrates three large sets of genomic data available through The Cancer Genome Atlas has identified 37 RNA molecules that might predict survival in patients with the most common form of breast cancer. The study by researchers at the Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC - James) initially analyzed messenger RNA (mRNA) and microRNA expression, DNA methylation data and clinical findings for 466 patients with invasive ductal carcinoma, the most common type of breast cancer...


In the quest for better cancer medicines, vaccines that treat rather than prevent disease are getting lots of attention. More than 90 clinical trials have tested therapeutic vaccines in cancer patients, but the results have been a mixed bag. A recent study in mice suggests that changing a traditional ingredient in the vaccines could make a big difference.

Peanut, who was diagnosed with non-Hodgkin lymphoma, is not the first great ape to be treated for cancer like a human. An orangutan with advanced stage cancer at the National Zoo in Washington had surgery to remove a cancerous intestinal tumor in 2000. In 2009, two female gorillas at the North Carolina Zoo underwent radiation therapy. All three cases involved much older apes, in their 30s or 40s, and all had to be euthanized.

 


Now scientists have discovered a vital clue to unraveling these riddles. The human genome is packed with at least four million gene switches that reside in bits of DNA that once were dismissed as “junk” but that turn out to play critical roles in controlling how cells, organs and other tissues behave.
