miRNA Regulated Networks Identified in Cystic Fibrosis
News May 21, 2013
Integrated DNA Technologies (IDT) offers insight into recent research that has unearthed an miRNA-regulated network implicated in the pathogenesis of Cystic Fibrosis (CF). Described in the April edition of DECODED, the international IDT customer newsletter, optimized DIG-labeled DsiRNAs (IDT) were used to develop a novel, enhanced approach for oligonucleotide delivery. Using this delivery technology, researchers led by Dr Paul McCray and Dr Beverly Davidson (Department of Pediatrics, Carver College of Medicine, University of Iowa, IA, USA) showed that the introduction of an miR-138 mimic, developed by IDT, resulted in knockdown of the transcriptional regulator SIN3A, subsequently leading to improved CFTR anion channel functionality on the cell surface, and a partially rescued phenotype.
The discovery sheds light on a previously unrecognized mechanism of CFTR processing, and opens up exciting possibilities for novel therapeutic targets in CF. Dr McCarthy commented on the strength of the collaboration with IDT, observing how the quality of the oligos remained intact for the entirety of the experiments, and provided them with “a really robust tool to look at the questions we were asking”.
Habitat loss, habitat fragmentation and the loss of genetic diversity are the main factors driving the extinction of many wild species, and the few eastern massasauga rattlesnakes remaining in Illinois have certainly suffered two of the three. A long-term study of these snakes reveals, however, that – despite their alarming decline in numbers – they have retained a surprising amount of genetic diversity.READ MORE
Researchers have discovered a navigational gene in glass catfish called the electromagnetic-perceptive gene, or EPG, that responds to certain magnetic waves. These findings have the potential to revolutionize treatments for humans and help those who suffer from tremors related to Parkinson’s and seizures associated with epilepsy.
