CRF receptor type 1 mediates continual hypoxia-induced CRF peptide and CRF mRNA expression increase in hypothalamic PVN of rats
چکیده انگلیسی
We demonstrated previously that hypoxia activated CRF and CRF mRNA in PVN, and CRF receptor 1 (CRFR1) mRNA in rat pituitary. The aim of the study is to test whether the hypoxia-activated CRF and CRF mRNA is associated with triggering CRFR1. Rats were exposed to hypobaric hypoxia at altitude of 2 and 5 km. CRF and CRF mRNA were assayed by immunostaining and in situ hybridization. CRFR1 mRNA was assayed by RT-PCR. Results showed that 5 km continual hypoxia increased CRF and CRF mRNA in PVN, CRFR1 mRNA in pituitary, and plasma corticosterone. The hypoxia-increased CRF, CRF mRNA, CRFR1 mRNA, and corticosterone were blocked by CRFR1 antagonist (CP-154,526), suggesting that CRFR1 in PVN and pituitary are responsible for the hypoxia-increased CRF and CRF mRNA in PVN.
