- Scientists have proposed a new mechanism for molecular genetics [Nature] - the evolution of the ribosome.
- Making neural stem cells pluripotent with the tweaking of one gene Oct4 [Nature]
- Tumor progression gene not so incognito anymore! [RPI]
- A gene mutation that may explain the association between osteoporosis and atherosclerosis [Artery Research]
- Interesting interview with Haifan Lin about moving from stem cells to identifying important genes that allow for their multipotency (etc.). [Nature]
- Conus purpurascens venom operates this way:
As far as we know, the venom effect is due to many types of conotoxins that act in synergetic way. The W-conotoxins hinder the entry of the calcium into the nerve ending and inhibit the acetylcholine release. The M-conotoxins modify the sodium canals in the muscular cells. The A-conotoxins block the nicotinic acetylcholine receptors. Olivera and colleagues have emphasized the importance of two different types of peptides isolated in Conus purpurascens - the conantokins and the omega-conotoxins - in the nerve ending inhibition. A peptide that induces drowsiness in the guinea pig has been isolated in Conus geographus.
