Project description:Gene expression profiling reveals a potential role of Luteolin in human neuronal stem cells (hNSCs) differentiation . hNSCs purchased from Gibco were treated with 1 μM verbenalin for 24 hours. Microarray gene expression profiling was conducted for biological replicates of hNSCs cultured in differentiation cell culture medium supplemented with Luteolin for 24 hours and untreated control cells cultured in differentiation cell cultured medium .
Project description:Gene expression profiling reveals a potential role of Luteolin in LPS induced depression model LPS depression induced mice were orally treated with luteolin (10 mg/kg body weight) once per day during 8 consecutive days. Microarray gene expression was conducted for isolated mice Neural Stem Cells (NSCs) . Two mice brain were used for each expermient. The Microarray gene expression was conducted on NSCs and hipocampus from LPS depression induced depression mice (LPS group), LPS depression induced depression mice treated with luteolin(LPS+L group), Normal mice (PBS group) and Normal mice treated with luteolin (PBS+L).

Project description:To investigate the function of Luteolin and siVRK1 on ovarian cancer, we use A2780 and ES2 cell lines treated with siCtrl, siVRK1, DMSO and luteolin to do the experiment. We then performed gene expression profiling analysis using data obtained from RNA-seq .
Project description:Parkinson’s disease (PD) is one of the most common neurodegenerative disease caused by diminution of neurons in the substantia nigra (SN) which projects dopaminergic (DA) axons to the striatum and other target areas. Recently, accumulating data demonstrated the prospects of cell replacement therapy by using neural stem cell (NSCs) transplantation. However the mechanisms underlying the potential efficacy are not fully understood. To gain new insights into the mechanisms of 6-OHDA induced lesion and potential efficacy of hNSCs transplantation, Intrastriatal 6-Hydroxydopamine (6-OHDA) injected parkinsonian mice were unilaterally engrafted with undifferentiated human NSCs to striatum (ST). High-throughput quantitative proteomic approach was utilized to characterize the proteome profiles of PD related brain regions in these mice including SN, ST, olfactory bulb (OB) and subventricular zone (SVZ). The abundance of more than 5000 proteins with high confidence in each region was determined in this study which represents the most extensive proteomic study of PD mouse models to date. In addition to the disruption of the DA system, the quantitative analysis demonstrated the profound disturbance of SVZ proteome after 6-OHDA insult, in which the abundance of more than 20% proteins was significantly changed. After hNSCs engraftment, the proteome of SVZ was restored and the astrocytes in ST was greatly activated in companion with the increase in neurotrophic factors. Furthermore, bioinformatics analysis demonstrated that changes in proteome was not caused by the proliferation of hNSCs or their progeny, but rather by the reaction of endogenous cells. Overall, this study reveals that hNSCs benefits parkinsonian animals by eliciting endogenous responses in multiple brain regions, and discovers the unexpected role of SVZ cells in PD progress and treatment, providing new therapeutic targets.
Project description:To determine if any altered miRNA expression is actually involved in the growth inhibition and/or cell death induction by luteolin and/or gefitinib, we performed miR-array analysis using RNA from PC-3 cells after 24h of treatment with 60μM luteolin and/or 60μM gefitinib. PC-3 cells were treated for 24h with DMSO, 60μM luteolin (Lut), 60μM gefitinib (Gef) or their co-administration (Lut+Gef). Each sample was run in duplicate.
Project description:Induced pluripotent stem (iPS) cells have been generated from mouse and human somatic cells by ectopic expression of the four transcription factors (OCT4, SOX2, c-MYC, KLF4). We previously reported that Oct4 alone is sufficient to directly reprogram adult mouse neural stem cells (NSCs) to iPS cells. Here, we report the generation of one-factor (1F) human iPS from human NSCs (1F hNiPS) by ectopic expression of Oct4 alone. 1F hNiPS cells resemble human embryonic stem cells (hESCs) in global gene expression profiles, epigenetic status and pluripotency in vitro and in vivo. These findings demonstrate that the transcription factor OCT4 is sufficient to reprogram human NSCs to pluripotency. 1F iPS cell generation will accelerate this field further towards understanding reprogramming and generating patient-specific pluripotent stem cells. For transcriptome profiling, 400 ng of total DNA-free RNA was used as input for labelled cRNA synthesis (Illumina TotalPrep RNA Amplification Kit - Ambion) following the manufacturer's instructions (IVT: 10h). Quality-checked cRNA samples were hybridized as biological or technical duplicates for 18 h onto HumanRef-8 v3 expression BeadChips (Illumina), washed, stained, and scanned following guidelines and using materials / instrumentation supplied / suggested by the manufacturer. Five sample types were analyzed, each one of them in duplicate. hNSC: human fetal neural stem cells (duplicates); 1F hNiPS: One factor (Oct4) human iPS cells from hNSCs, hand-picked cols (duplicates); 2F hNiPS: Two factors (Oct4,Klf4) human iPS cells from hNSCs, hand-picked cols (duplicates); H9 hESC: H9 human ESCs grown on low-density CF1 MEFs (duplicates); H1 hESC: H1 human ESCs grown on low-density CF1 MEFs (duplicates).
