Indeed, unlike other thiols, homocysteine incubation with endothelial cells induces an increased expression of the stress protein GRP78 and a decreased expression of glutathione peroxidase, a major intracellular antioxidant enzyme, through a mechanism that depends on an alteration of the intracellular redox potential (Kokame et al, 1996
BPC 157 application largely counteracted changes at the microscopic level, including the formation of vacuoles and the loss of axons in the white matter, the formation of edema and the loss of motoneurons in the gray matter, and a decreased number of large myelinated axons in the rat caudal nerve from day 7
