DNA News and Research

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).

New substance can replace nucleoside thymidine in DNA biosynthesis

Interactions of biological macromolecules are the central bases of living systems. Biological macromolecules are synthesized in living cells by linking many small molecules together. Naturally occurring macromolecules include genetic materials (DNA) and proteins. A detailed understanding of the synthesis of these macromolecules in whole animals is a basic requirement for understanding biological systems, and for the development of new therapeutic strategies.

Researchers identify interactive pathway that regulates cancer metastasis

Finding ways to counteract or disrupt the invasive nature of cancer cells, called "metastasis," has been a long-term goal of cancer researchers. Now, researchers at Moffitt Cancer Center in Tampa, Fla., have identified an interactive pathway that regulates metastases in some cancers that may be vulnerable to chemical targeting in order to prevent cancer cell proliferation and tumor growth.

People with myotonic muscular dystrophy more likely to develop cancer

People who have the most common type of adult muscular dystrophy also have a higher risk of getting cancer, according to a paper published today in the Journal of the American Medical Association.

Vorinostat in addition to chemotherapy drugs improves remission rates in AML patients

Adding a drug that activates genes to frontline combination therapy for acute myeloid leukemia resulted in an 85 percent remission rate after initial treatment, researchers at The University of Texas MD Anderson Cancer Center reported at the 53rd Annual Meeting of the American Society of Hematology.

Scientists identify gene mutation behind Waldenstrom's macroglobulinemia

Scientists at Dana-Farber Cancer Institute have identified a gene mutation that underlies the vast majority of cases of Waldenstrom's macroglobulinemia, a rare form of lymphoma that has eluded all previous efforts to find a genetic cause.

DNA sequencing identifies new altered genes that drive CLL

The most comprehensive search to date of DNA abnormalities in chronic lymphocytic leukemia (CLL) has unearthed several new altered genes that drive this common blood cancer, a finding that could potentially help doctors predict whether an individual patient's disease will progress rapidly or remain indolent for years, say scientists from Dana-Farber Cancer Institute and the Broad Institute.

NIH, Autism Speaks announce addition of AGRE as data federation site for NDAR

Autism Speaks - North America's largest autism science and advocacy organization - joins the National Institutes of Health (NIH) in announcing the addition of Autism Speaks Autism Genetic Resource Exchange (AGRE) as a data federation site for the National Database for Autism Research (NDAR). The addition of AGRE data will help create the largest multidisciplinary source of autism research data to date.

Celgene reports final results from REVLIMID plus VIDAZA phase II study on higher-risk MDS

Celgene International Sàrl, a subsidiary of Celgene Corporation, today reported final results from the phase II portion of a multi-center phase I/II study evaluating combination therapy with REVLIMID (lenalidomide) and VIDAZA (azacitidine) in patients with higher-risk myelodysplastic syndromes (MDS) not previously treated with either drug.

Scientists identify genetic alteration behind anophthalmia

Scientists at University College Dublin, Ireland, have identified a genetic alteration which causes a child to be born with no eyes - a condition called anophthalmia.

Gene therapy for bleeding disorder Hemophilia B

In a landmark study, researchers used gene therapy to successfully treat six patients with severe hemophilia, a blood-clotting disorder. Despite the early nature of the study, it is promising. A single infusion using the new treatment worked in some patients for more than a year, boosting their clotting ability significantly.

Research assesses safety and efficacy of pre-operative transfusions, hydroxyurea therapy for SCD

Research assessing the safety and efficacy of hydroxyurea therapy in pediatric patients with sickle cell disease (SCD) and the use of pre-operative transfusions for patients with SCD who undergo low- and moderate-risk elective surgery will be presented today at the 53rd Annual Meeting of the American Society of Hematology.

Onconova announces data from five rigosertib clinical trials on MDS

Onconova Therapeutics announces three presentations relating to clinical trials of its Phase III-stage anticancer agent, rigosertib sodium (Estybon or ON 01910.Na), at the 53rd American Society of Hematology (ASH) Annual Meeting in San Diego, CA, December 10-13, 2011.

Suppressing STARD9 protein could be a novel strategy to fight cancers

Suppressing a newly identified and characterized protein involved in regulating cell division could be a novel strategy to fight certain cancers because it stops the malignant cells from dividing and causes them to die quickly, according to a study by researchers with UCLA's Jonsson Comprehensive Cancer Center.

Researchers shown how BRCA1 inactivation raises cancer risk

Working with human breast cells, researchers at the Johns Hopkins Kimmel Cancer Center have shown how the inactivation of a single copy of the breast cancer gene BRCA1 leaves breast cells vulnerable to cancer by reducing their ability to repair DNA damage, causing genetic instability.

Gene therapy can reduce painful bleeding episodes in patients with hemophilia B

Symptoms improved significantly in adults with the bleeding disorder hemophilia B following a single treatment with gene therapy developed by researchers at St. Jude Children's Research Hospital in Memphis and demonstrated to be safe in a clinical trial conducted at the University College London (UCL) in the U.K.
