Prostaglandin E2 (PGE2), one product of inflammatory reactions, and PGA1, which is formed during PGE2 extraction, induce degeneration in adenosine 3',5'-cyclic monophosphate (cAMP)-induced differentiated neuroblastoma (NB) cells in culture. The mechanisms of action of PGE2 on neurodegeneration are not well understood. To investigate this, we have utilized(More)
Inflammatory reactions are considered one of the important etiologic factors in the pathogenesis of Alzheimer's disease (AD). Prostaglandins such as PGE2 and PGA1 and free radicals are some of the agents released during inflammatory reactions, and they are neurotoxic. The mechanisms of their action are not well understood. Increased levels of beta-amyloid(More)
Background—Estrogens have vascular effects through the activation of estrogen receptors (ERs). In addition to ER␣, the first ER to be cloned, a second subtype called ER␤ has recently been discovered. Methods and Results—Using a reverse-transcriptase polymerase chain reaction assay that employs the same primer pair to simultaneously amplify ER␣ and ER␤(More)
