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).

Habitual dietary intake of monozygotic twins associated with fecal microbiota composition

The establishment of microbial populations in the gastrointestinal-tract is a complex process, involving microbial and host interactions eventually resulting in a dense and stable population.

Scientists reveal surprising role for HDAC1 proteins in development of skin tumors

Findings by scientists from the Max F. Perutz Laboratories (MFPL) of the University of Vienna and the Medical University of Vienna reveal a surprising role for histone deacetylase 1 (HDAC1) - a member of a family of chromatin modifying proteins - in the development of skin tumors.

Researchers identify genes that put children at high risk of serious asthma attacks

An international team spearheaded by researchers from the University of Copenhagen has identified the genes that put some children at particularly high risk of serious asthma attacks, including one not previously suspected of being implicated in the disease.

Close to 100 novel human gene regions that code for proteins may be linked to cancer

By using a new analysis method, researchers at Karolinska Institutet and Science for Life Laboratory (SciLifeLab) in Sweden have found close to one hundred novel human gene regions that code for proteins. A number of these regions are so-called pseudogenes, which may be linked to cancer.

Scientists discover gene associated with high risk of severe childhood asthma.

An international scientific team has discovered a gene associated with a high risk of severe childhood asthma. The specific gene variant may be an actual cause of this form of asthma, a leading cause of hospitalization in young children.

Heidelberg scientists identify protein motifs that influence gene silencing

Bioscientists at Heidelberg University have studied the function of certain proteins, known as Argonaute (Ago) proteins, in the process of gene regulation. They sought to understand why only the Ago2 protein is able to target and directly turn off genes in humans, while the closely related Ago3 protein is not.

European Commission grants marketing authorization for Bayer HealthCare's Xofigo injection

Bayer HealthCare announced today that the European Commission has granted marketing authorization for Xofigo (radium Ra 223 dichloride) solution for injection for the treatment of adults with castration-resistant prostate cancer, symptomatic bone metastases and no known visceral metastases. This decision follows a positive recommendation from the European Committee for Medicinal Products for Human Use in September of this year.

Acquired resistance to cancer therapies: an interview with Dr Rajendra Kumari, Chief Scientific Officer at PRECOS

Cancer can be treated by a number of different ways depending on the location, grade and stage of tumour. A patient's age, medical history and lifestyle will also be taken into consideration and a combination of treatments will also be adopted to provide maximum effect.

Researchers generate most complete genome sequences from single cells and individual neurons

Researchers led by bioengineers at the University of California, San Diego have generated the most complete genome sequences from single E. coli cells and individual neurons from the human brain. The breakthrough comes from a new single-cell genome sequencing technique that confines genome amplification to fluid-filled wells with a volume of just 12 nanoliters.

Cardiologists question FDA recommendations on genetic testing before taking Plavix

Which antiplatelet medication is best after a coronary stent? The costly and potential life-or-death question lingers after most of the 600,000 angioplasties performed every year in the United States. The answer may lie in your genes, but professional cardiovascular societies and many working cardiologists question the U.S. Food and Drug Administration's recent recommendation that patients undergo genetic testing before taking Plavix (clopidogrel bisulfate).
