Hydroxysafflor yellow A ameliorates depression-like behavior in Parkinson's disease mice.
Pakistan journal of pharmaceutical sciences(2024)
Abstract
Depression is a common non-motor symptom of Parkinson's disease. Previous studies demonstrated that hydroxysafflor yellow A had properties of improving motor symptoms of Parkinson's disease. The effect of hydroxysafflor yellow A on depression in Parkinson's disease mice is investigated in this study. To induce Parkinson's disease model, male Swiss mice were exposed to rotenone (30 mg/kg) for 6 weeks. The chronic unpredictable mild stress was employed to induce depression from week 3 to week 6. Sucrose preference, tail suspension, and forced swimming tests were conducted. Golgi and Nissl staining of hippocampus were carried out. The levels of dopamine, 5-hydroxytryptamine and the expression of postsynaptic density protein 95, brain-derived neurotrophic factor in hippocampus were assayed. It showed that HSYA improved the depression-like behaviors of Parkinson's disease mice. Hydroxysafflor yellow A attenuated the injury of nerve and elevated contents of dopamine, 5-hydroxytryptamine in hippocampus. Treatment with hydroxysafflor yellow A also augmented the expression of postsynaptic density protein 95 and brain-derived neurotrophic factor. These findings suggest that hydroxysafflor yellow A ameliorates depression-like behavior in Parkinson's disease mice through regulating the contents of postsynaptic density protein 95 and brain-derived neurotrophic factor, therefore protecting neurons and neuronal dendrites of the hippocampus.
