Abstract

Chemical castration using luteinizing hormone-releasing hormone agonists and/or anti-androgens is an alternative to surgical castration. Goserelin and bicalutamide are representative drugs used for chemical castration. The effects of chemical castration on sexual functions are well documented; however, the possibility that chemical castration might induce undesirable effects on brain functions has been raised. We investigated the effects of chemical castration and surgical castration on spatial learning ability in relation to cell proliferation and apoptosis in hippocampus. Bilateral orchiectomy was performed for surgical castration, and chemical castration was induced by treatment with goserelin or bicalutamide for 28 days. To find out the effects of goserelin and bicalutamide with those of orchiectomy on the spatial learning ability, radial eight-arm maze test was performed. To find out the effects of goserelin and bicalutamide with those of orchiectomy in relation to cell proliferation and apoptosis in the hippocampus, terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling staining, and immunohistochemistry for 5-bromo-2'-deoxyuridine, doublecortin, and caspase-3 were performed. Western blot for brain-derived ...Continue Reading

Brain Injury & Trauma

brain injury after impact to the head is due to both immediate mechanical effects and delayed responses of neural tissues.

BCL-2 Family Proteins

BLC-2 family proteins are a group that share the same homologous BH domain. They play many different roles including pro-survival signals, mitochondria-mediated apoptosis and removal or damaged cells. They are often regulated by phosphorylation, affecting their catalytic activity. Here is the latest research on BCL-2 family proteins.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
