QRT-PCR analysis of the regulation of NTS PPG and TH transcription by chronic subcutaneous administration of corticosterone (3.5 mg/kg). a, b, Chronic injection of corticosterone decreased PPG mRNA and hnRNA expression compared with the vehicle treatment. c, d, Chronic corticosterone injection did not affect the NTS TH gene expression. e, The plasma corticosterone level was increased by acute subcutaneous injection of corticosterone at 10 mim, reached the peak at 30 min, and maintained elevated levels at 60 and 120 min compared with the vehicle injection. *p < 0.05 versus control.
