STUDIES ON NEUROPEPTIDE-Y EFFLUX FROM ADULT RAT ADRENAL MEDULLA – EFFECT OF CHRONIC INTERMITTENT HYPOXIA

Ramakrishnan, Devi Prasadh

Abstract Details

2008, Master of Sciences, Case Western Reserve University, Biochemistry.
Chronic intermittent hypoxia (CIH) augments norepinephrine (NE) efflux to acute hypoxia in adult rat adrenal medulla (AM). Neuropeptide-Y (NPY) is shown to be co-stored with NE and facilitate its release from AM through NPY-Y1 receptor. This study examines if CIH alters NPY efflux from adult rat AM and, if so, by what mechanism(s), and the effect of NPY on CIH induced increase in blood pressure. NPY and NE effluxes were studied from ex vivo AM. Results of this study show that while acute hypoxia and acidic hypercapnia augments NPY efflux, isohydric hypercapnia and nicotine inhibited NPY efflux in CIH exposed AM. NPY, by facilitating NE efflux through NPY-Y1 receptor, contributes to CIH induced blood pressure raise. Antioxidant treatment restored the nicotine-evoked and inhibited acute hypoxia-evoked NPY efflux from AM of rats exposed to CIH suggesting mechanisms involving oxidant radicals are responsible for CIH induced alterations in NPY efflux.
