Ginseng total saponins (GTS) are the major active components of Panax ginseng C.A. Meyer, which has been used as a popular tonic herb for 2000 years in Far East countries. In the present study, two classic animal models: the forced swimming test (FST) and the chronic mild stress (CMS) model were used to evaluate the antidepressant-like activities of GTS. It(More)
The development of the cancer stem cell (CSCs) niche theory has provided a new target for the treatment of gliomas. Gene therapy using oncolytic viral vectors has shown great potential for the therapeutic targeting of CSCs. To explore whether a viral vector carrying an exogenous Endo-Angio fusion gene (VAE) can infect and kill glioma stem cells (GSCs), as(More)
PURPOSE To investigate the morphologic and molecular consequences of 30- and 90-minute central retinal artery ligation (CRAL)-induced retinal ischemia, followed by 3 and 12 hours of reperfusion, and to identify potential targets for therapy. METHODS Retinal ischemia was induced for 30 and 90 minutes by ligating the rat central retinal artery, and(More)
Frontotemporal dementia (FTD) has been linked to mutations in the progranulin gene (GRN) that lead to progranulin (PGRN) haploinsufficiency. Thus far, our understanding of the effects of PGRN depletion in the brain has been derived from investigation of gross pathology, and more detailed analyses of cellular function have been lacking. We report that(More)
Null mutations in the progranulin gene (PGRN) have been identified as a major cause of frontotemporal dementia with ubiquitinated inclusions. In this disorder, ubiquitinated, aggregated protein inclusions of a normally nuclear-located RNA processing protein called TAR DNA binding protein (TDP-43) accumulate in the neuronal cytoplasm (FTLD-TDP). To determine(More)
We report the first demonstration that Krüpple-like factor 4 (KLF4) mRNA is dramatically and rapidly upregulated by NMDA application in primary cortical neuron cultures. We also report that NMDA induced significant and transient upregulation of KLF4 protein expression, in both cortical neuron cultures and native brain slices. The increase of KLF4 mRNA and(More)
Ginseng has been used for mood adjustment in traditional Chinese medicine for thousands of years. Our previous study has shown that, total ginsenosides, the major pharmacologically functional ingredients of ginseng, possess antidepressant activity. In the present study, we hypothesized that an intestinal metabolite of ginseng, 20(S)-protopanaxadiol (code(More)
PURPOSE Advanced castration-resistant prostate cancer, for which there are few treatment options, remains one of the leading causes of cancer death. MicroRNAs (miRNA) have provided a new opportunity for more stringent regulation of tumor-specific viral replication. The purpose of this study was to provide a proof-of-principle that miRNA-regulated oncolytic(More)
Kai Xin San (KXS), a traditional Chinese herbal medicine, has been used clinically for the treatment of depressive disorders and cognitive impairment for centuries. However, the effects of KXS on cognitive dysfunction induced by depression have not been evaluated scientifically. The present study aimed to explore the antidepressant-like and nootropic(More)
BACKGROUND Significant protease activations have been reported after traumatic brain injury (TBI). These proteases are responsible for cleavage of transmembrane proteins in neurons, glial, and endothelial cells and this results in the release of their extracellular domains (ectodomains). METHODS Two TBI models were employed here, representing both closed(More)
