Andy, I thought that the board was a bit too quite. Its now in the #1 slot on the Hot Topics board. I'll post the Reuter's article on the diabetes paper to you. Peter seems a bit overwhelmed although he made the comment about consultants and wanted some references for LGND's science. The Nature reference is at the bottom of the Reuter's story: Here's a Reuter's report on the Nature publication showing that Rexinoids synergize with TZDs: New Class Of Retinoids Improves Insulin Utilization
WESTPORT, Apr 02 (Reuters) - A new class of retinoids that act as insulin sensitizers enable mice with non-insulin dependent diabetes mellitus to use insulin more efficiently, according to an article in the March 27 issue of Nature.
Lead author Dr. Ranjan Mukherjee of Ligand Pharmaceuticals in San Diego, California reports that he and his colleagues have been able to show that retinoid X receptor-selective agonists, which they call rexinoids, replicate the activity of ligands for a variety of hormone receptors. Dr. Mukherjee explains that because one such receptor, known as peroxisome proliferator activated receptor-gamma, is a target for antidiabetic agents, his group "...investigated whether retinoid X receptor ligands could alter insulin and glucose signaling."
According to Dr. Mukherjee, rexinoids do indeed "...function as insulin sensitizers and can decrease hyperglycaemia, hypertriglyceridaemia, and hyperinsulinaemia. This antidiabetic activity can be further enhanced by combination treatment with [peroxisome proliferator activated receptor-gamma] agonists, such as thiazolidinediones."
"The biological activity of [retinoid X receptor] ligands is different from that of retinoids that activate the retinoic acid receptors," Dr. Mukherjee writes. "Therefore, it is appropriate that [retinoid X receptor] activators be considered a distinct class of pharmacologic agents and could be referred to as 'rexinoids' to distinguish their activity from 'retinoids'....These [retinoid X receptor] agonists appear to offer a new approach for the treatment of insulin resistance."
