摘要

To observe the effects of Huannao Yicong Formula (还脑益聪方

HYF) on learning and memory and it’s regulating effect on γ-secretase related anterior pharynx defective 1 (APH-1)

presenilin enhancer-2 (PEN-2) signaling pathway

so as to discuss and further clarify the mechanism of HYF on Alzheimer’s disease. Sixty APP/PS1 transgenic mice

randomly allocated into 4 groups

the model group

the donepezil group (0.65 mg/kg)

HYF low-dose group (HYF-L

5.46 g/kg) and HYF high-dose group (HYF-H

10.92 g/kg)

15 for each group. Another 15 C57BL/6J mice with the same age and same genetic background were allocated into the control group

proper dosage of drugs or distilled water were given by intragastric administration once daily for 12 weeks. After 12 weeks of administration

the learning and memory abilities of mice in each group was evaluated by the morris water maze test

amyloid precursor protein (APP)

Aβ1-40 and Aβ1-42 levels in hippocampus were detected by enzyme-linked immunosorbent assay

γ-secretase was detected by dual luciferase assaying

the levels of APH-1a

hypoxia-inducible factor 1α (HIF-1α)

cAMP response element-binding protein (CREB) and PEN-2 and their mRNA expression was measured by Western blot and real-time polymerase chain reaction. HYF can ameliorate learning and memory deficits in APP/PS1 transgenic mice by decreasing the escape latency

improving the number of platform crossing and swimming speed (P<0.01

P<0.05). HYF can decrease the levels of APP

Aβ1-40

Aβ1-42 and the activity of γ-secretase in hippocampus of Alzheimer’s disease model mice. HYF can down-regulate the levels of CREB and PEN-2 and the expression of their mRNA. HYF can improve the learning and memory ability by inhibiting the activity of γ-secretase through the CREB/PEN-2 signaling pathway

and this may be one of the therapeutic mechanisms of HYF in Alzheimer’s disease.
