Neuroscience
. 2014 Dec;
284:751-758.
PMID: 25451290
Eider duck (Somateria mollissima) cerebellar neurons are highly tolerant toward hypoxia in vitro, which in part is due to a hypoxia-induced depression of their spontaneous activity. We have studied whether...

40(45):13520-8.
PMID: 11695899
Small molecules with insulin mimetic effects and oral availability are of interest for potential substitution of insulin injections in the treatment of diabetes. We have searched databases for compounds capable...

. 1998 Nov;
284(2):477-88.
PMID: 9813131
Studies of naturally occuring and chemically modified insulins have established that the NH2-terminal helix of the A-chain is important in conferring affinity in insulin-receptor interactions. Nevertheless, the three-dimensional structural basis...

J Mol Biol
. 1998 Jun;
279(1):1-7.
PMID: 9636695
Despite years of effort to clarify the structural basis of insulin receptor binding no clear consensus has emerged. It is generally believed that insulin receptor binding is accompanied by some...
