Inhibitors of advanced glycation and endoplasmic reticulum stress.

abstract：:Mutations in regulators and effectors of the Rho GTPases underlie various forms of mental retardation (MR). Among them, oligophrenin-1 (OPHN1), which encodes a Rho-GTPase activating protein, was one of the first Rho-linked MR genes identified. Upon characterization of OPHN1 in hippocampal brain slices, we obtained evi...
