Post-stroke depression (PSD) is a prevalent complex psychiatric disorder that causes delay to functional recovery from rehabilitation and also increases cognitive impairment. The etiology of PSD remains controversial and appears to be physical and psycho-social in origin, alone or in combination. The causes of PSD as well as the mechanisms conferring(More)
Triptolide (TP), one of the major active components of the traditional Chinese herb Tripterygium wilfordii Hook F, and 2, 4-diamino-6-hydroxypyrimidine (DAHP), an inhibitor of tetrahydrobiopterin (BH4) synthesis, have been reported to have potent anti-inflammatory and immunosuppressive properties. However, the protective effects of TP and DAHP on cerebral(More)
It has previously been demonstrated that ischemic stroke activates autophagy pathways; however, the mechanism remains unclear. The aim of this study is to further investigate the role that autophagy plays in cerebral ischemia. 2, 4-diamino-6-hydroxy-pyrimidine (DAHP), for its nitric oxide synthase (NOS) inhibiting neuroprotective effect, and triptolide(More)
Stroke is the leading cause of neurological disability in humans. Middle cerebral artery occlusion (MCAO) followed by reperfusion is widely accepted to mimic stroke in basic medical research. Triptolide is one of the major active components of the traditional Chinese herb Tripterygium wilfordii Hook F, and has been reported to have potent anti-inflammatory(More)
OBJECTIVES Mechanisms that regulate proliferation of adult neural stem cells are largely unknown. Here, we have investigated the role of microR-30c (miR-30c) and its target, semaphoring 3A (sema3A), in regulating adult neurogenesis and mechanisms underlying this process. MATERIALS AND METHODS In situ hybridization, immunofluorescence and quantitative(More)
Amniotic fluid (AF) continuously exchanges molecules with the fetus, playing critical roles in fetal development especially via its complex components. Among these components, microRNAs are thought to be transferred between cells loaded in microvesicles. However, the functions of AF microRNAs remain unknown. To date, few studies have examined microRNAs in(More)
Adult neurogenesis is considered to contribute to a certain degree of plasticity for the brain. However, the effects of adult-born neurons on the brain are still largely unknown. Here, we specifically altered the expression of miR-30c in the subventricular zone (SVZ) and dentate gyrus (DG) by stereotaxic injection with their respective up- and(More)
