This paper describes acetylcholinesterase (AChE) activity in the dorsal thalamus of several rodents, including rat, mouse, gerbil, hamster and guinea pig. Tissue from fetal, neonatal, and adult animals was studied using histochemical techniques. Developing animals of all species display prominent AChE staining in the ventral medial geniculate nucleus and(More)
Previous studies have demonstrated that transient patterns of acetylcholinesterase (AChE) activity are characteristic of geniculo-recipient regions of rat cortical area 17 during the second and third postnatal weeks of life. Neonatal enucleation results in a marked reduction of this transiently expressed cortical AChE. Parallel studies have demonstrated(More)
PURPOSE To examine the involvement of c-Fos protein in light-induced photoreceptor cell death in rats. METHODS Thirty-two Lewis albino rats were exposed to green fluorescent light (480-520 nm) of 300 to 320 foot-candles (3228-3443.2 lux) for 3 hours, allowed to recover in the dark, and euthanatized at 0, 1, 3, 6, 12, 24, or 96 hours after light exposure.(More)
Transforming growth factor-beta superfamily regulates many aspects of reproduction in the female. We identified a novel member of this family, growth-differentiation factor 8 (GDF-8) in the 72 h post coital uterine fluid of the golden hamster by proteomic techniques. Uterine GDF-8 mRNA decreased as pregnancy progressed while its active protein peaked at 72(More)
