DNA News and Research

RSS

DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

EMA accepts Pfizer's regulatory submissions of two investigational cancer drugs for review

Pfizer Inc. announced today that the European Medicines Agency (EMA) has accepted Pfizer's regulatory submissions for review of two investigational compounds - crizotinib, an oral first-in-class anaplastic lymphoma kinase (ALK) inhibitor, for the treatment of patients with previously treated ALK-positive advanced non-small cell lung cancer (NSCLC); and bosutinib for the treatment of adult patients with newly diagnosed Philadelphia chromosome positive (Ph+) chronic myeloid leukemia (CML) in the chronic phase.

Autism risk in siblings of autistic children is higher: Study

A new study reveals that parents with an autistic child have a 19% increased chance of getting another one with a similar disorder. Experts said the study, published Monday in the journal Pediatrics, is the most comprehensive of its kind and should be used to counsel families.

Inherited genetic links to prostate cancer discovered

Researchers from the U.S. and Sweden have linked five inherited genetic mutations to the development of a particularly aggressive and deadly form of prostate cancer. They suggest that these findings could someday lead to development of an easy-to-administer blood test to screen for such mutations to help physicians assess the long-term risk faced by newly diagnosed prostate cancer patients.

Researchers identify oncoprotein that allows MCV virus to trigger Merkel Cell Carcinoma

Researchers at the University of Pittsburgh Cancer Institute (UPCI) have identified the oncoprotein that allows a common and usually harmless virus to transform healthy cells into a rare but deadly skin cancer called Merkel Cell Carcinoma.

Customized computer models may identify patients at risk of Lynch syndrome

People who are at risk for a certain form of colon and other types of cancer may soon have a better chance at surviving or even avoiding the diseases, thanks to a new study done by the Intermountain Clinical Genetics Institute at LDS Hospital.

Caffeine might help prevent skin cancer

A new Rutgers study strengthens the theory that caffeine guards against certain skin cancers at the molecular level by inhibiting a protein enzyme in the skin, known as ATR. Scientists believe that based on what they have learned studying mice, caffeine applied directly to the skin might help prevent damaging UV light from causing skin cancer.

Anti-health law measure secures place on Ohio ballot; mental health improvements hit snags in Milwaukee

The Ohio Supreme Court ruled on Friday that a proposed amendment to the state constitution that would block implementation of President Barack Obama's signature health care overhaul law can appear on the ballot this fall. The ruling came on the same day that a federal appeals court in Atlanta struck down the requirement in the law that Americans either carry health insurance or face penalties.

Caffeine in sunscreens may protect from skin cancer: Study

Studies have revealed that drinking caffeinated beverages reduces one’s chances of developing some types of cancer, including UV-associated skin cancer. Now, researchers propose a possible mechanism for this observation—the inhibition of a DNA repair pathway that sensitizes cells to death after sun exposure.

‘Methyl magnet’ genes can cause family cancer risk

Medical researchers have discovered a new type of mechanism causing cancer susceptibility, showing that tiny changes in some anti-cancer genes can act as magnets to attract modifying “biochemical tags”, effectively switching them off and predisposing families to an increased risk of the disease.
