Researchers confirm new drug development route for treating multiple sclerosis, asthma
Brazilian researchers who study a native venomous fish have confirmed a route to drug development for the treatment of chronic inflammatory diseases such as multiple sclerosis and asthma.
The venomous toadfish Thalassophryne nattereri contains a peptide (TnP) with anti-inflammatory and anti-allergic potential. Confirmation of this potential has now come via the zebrafish Danio rerio, a popular aquarium species native to South Asia that shares 70% of its genome with humans and is widely used as a model for in vivo trials in drug development.
The researchers tested TnP in D. rerio to measure its toxicity. In a little over a year, their research showed that the peptide is safe. It did not cause cardiac dysfunction or neurological problems in the toxicity tests they performed. ....

RNA editing events influence gene expression and phenotypic manifestation


RNA editing events influence gene expression and phenotypic manifestation
Combining computational mining of big data with experimental testing in the lab, researchers at Children s Hospital of Philadelphia (CHOP) have identified RNA editing events that influence gene expression and, in turn, the phenotypic manifestation of that expression.
In analyzing so-called A-to-I RNA editing, in which the adenosine of an RNA molecule is chemically modified into an inosine, the researchers describe how a single nucleotide change by RNA editing can have large downstream effects. The findings were published today in
Genome Biology.
Millions of A-to-I RNA editing sites have been identified across the human transcriptome, but the functions of most RNA editing events are unknown. Understanding how RNA editing affects gene expression and phenotype could help us unravel the genetic basis to many human conditions. ....
