22-11-2010: Retinitis pigmentosa is an inherited eye disorder characterized by progressive loss of vision that in many instances leads to legal blindness at the end stage.
In a ChIP-Seq based approach, the researchers identified a key regulatory role of the transcription factor Crx (Cone-rod homeobox) in the expression of retina-specific genes and thus described an important genetic basis for visual perception. In-depth analysis of Crx mediated regulation in photoreceptors with latest technology provided by Genomatix lead then to the identification of nonsense mutations in the human FAM161A gene, which are responsible for RP28-associated recessive retinitis pigmentosa. The group applied the Genomatix Genome Analyzer (GGA) to evaluate data from Crx chromatin immunoprecipitation coupled to massively parallel sequencing.

Follow-up to REDUCE study shows low rate of prostate cancer diagnosis
The four-year REDUCE (REduction by DUtasteride of prostate Cancer Events) clinical study evaluated prostate cancer risk reduction in men taking dutasteride, a 5-alpha-reductase inhibitor (5ARI) typically used to treat enlarged prostate. REDUCE results showed that dutasteride decreased the r ... more
A new genetic fingerprint lives in your belly
Our bodies contain far more microbial genes than human genes. And a new study suggests that just as human DNA varies from person to person, so too does the massive collection of microbial DNA in the intestine.The research is the first to catalog the genetic variation of microbes that live i ... more
Microbes - possible hitchhikers to space?
Bacteria are ubiquitous and some of them are real survival specialists – a property, which is particularly challenging for space missions. The spacecraft that are sent on their long journey into space should be as clean as possible and considerably reduced in microbial burden, since the ris ... more
