OPEN ACCESS

The generation of induced pluripotent stem cells (iPSCs) from somatic cells demonstrated that adult mammalian cells can be reprogrammed to a pluripotent state by the enforced expression of a few embryonic transcription factors.

"IscU, a proposed iron-sulfur cluster assembly scaffold protein, and CyaY, a bacterial frataxin homolog that has been postulated as an iron donor for the iron-sulfur cluster assembly, fail to bind any iron in E. coli cells under the same experimental conditions"

The paper focus on recent examples in which epigenetic modifications have been used to evaluate disease risk, progression and clinical response. It provide a broad overview of the accomplishments, remaining challenges and unrealized potential of epigenetic therapies in a range of diseases, with a particular emphasis on cancer.

On the Trail of the Epigenetic Code: Test System on Drosophila Should Provide the Key to Histone Function

ScienceDaily (Oct. 12, 2010) — Test system on Drosophila should provide the key to histone function. The genetic inherited material DNA was long viewed as the sole bearer of hereditary information. The function of its packaging proteins, the histones, was believed to be exclusively structural. Additional genetic information can be stored, however, and passed on to subsequent generations through chemical changes in the DNA or histones. read more

Microchip Technology Rapidly Identifies Compounds for Regrowing Nerves in Live Animals

ScienceDaily (Oct. 11, 2010) — Scientists have long sought the ability to regenerate nerve cells, or neurons, which could offer a new way to treat spinal-cord damage as well as neurological diseases such as Alzheimer's or Parkinson's. Many chemicals can regenerate neurons grown in Petri dishes in the lab, but it's difficult and time-consuming to identify those chemicals that work in live animals, which is critical for developing drugs for humans. read more
