The adenylate cyclase receptor complex and aqueous humor formation. [PDF]
The secretory tissue of the eye, the ciliary processes, contains an enzyme receptor complex, composed of membrane proteins, the catalytic moiety of the enzyme adenylate cyclase, a guanyl nucleotide regulatory protein (or N protein), and other features ...

Abstract Background Freshwater salinization is an emerging stressor in amphibian populations, and embryonic stages are most vulnerable. To better understand the variation in embryonic osmoregulation, we challenged embryos of two phylogenetically diverse anuran species, Xenopus laevis and Lithobates (Rana) sylvaticus, along a gradient of non‐lethal ...

Effect of oxytocin on free intracellular Ca2+ levels and progesterone release by human granulosa-lutein cells [PDF]
Oxytocin and its receptor are found in the corpus luteum in a variety of species, including the human. In the present study we used fura-2 microfluorimetry to investigate whether activation of the oxytocin receptor of cultured human granulosa-lutein ...

OECs, SCs, and Mel derive from SCPs. Sox10Cre;YapHet;TazKO mice show impaired SC maturation, reduced Mel formation, fewer SCPs, OECs, and olfactory neurons, but normal GnRH‐1 neuron migration. ABSTRACT Olfactory Ensheathing Cells (OECs) are glial cells originating from the neural crest and are critical for bundling olfactory axons to the brain.
