Transcription profiling of secondary neural stem cells from cortex and spinal cord reveals gene expression patterns consistent with regional derivation in culture

ABSTRACT: Neural stem cells (NSCs) can be isolated from different regions of the central nervous system. There has been controversy whether regional differences amongst stem and progenitor cells are cell intrinsic and whether these differences are maintained during expansion in culture. The identification of inherent regional differences has important implications for the use of these cells in neural repair. Here, we compared neural stem cells derived from the spinal cord and embryonic cortex. We found that while cultured cortical and spinal cord derived neural stem cells respond similarly to mitogens and are equally neuronogenic, they retain and maintain through multiple passages gene expression patterns indicative of the region from which they were isolated. Further microarray analysis identified 229 genes that were differentially expressed between cortical and spinal cord derived neurospheres. Experiment Overall Design: Cortex and and spinal cords were isolated from embryonic day 14 cd1 mice and cultured ad neurospheres for 2 passages in EGF and bFGF. 3 independent sets of cultures serve as biological replicates with a dye flip control for each hybridization, for a total of 6 arrays.

Project description:Despite extensive studies, the fundamental mechanisms responsible for the development and progression of heart failure have not yet been fully elucidated. Recent experimental and clinical studies have suggested that reactive oxygen species (ROS) play a major pathological role. Quercetin, a major flavonoid present in the human diet, has been studied widely and its biological properties are consistent with its protective role in the cardiovascular system. However, it remains unknown whether the cardioprotective effects of quercetin may also occur through the modulation of genes involved in cell survival. This study was therefore designed to examine the gene expression profiling of cultured rat primary cardiomyocytes supplemented with quercetin using DNA-microarrays and relating these data to functional effects. Experiment Overall Design: Primary heart cell cultures were obtained by isolation of cardiomyocytes from the ventricles of 2â4 day old Wistar rats and grown until complete confluence. In some dishes, 30 Î¼M quercetin was added to the culture medium for 6, 12 or 24 h. Total RNA was extracted using Total RNA Isolation Mini Kit (Agilent Technologies, Palo Alto, CA), following the manufacturerâs protocol. The yield and purity of the RNA were measured using NanoDrop ND-1000 Spectrophotometer (NanoDrop Technologies, Inc., Rockland, Del, USA). The 28s and 18s ribosomal bands were checked using Agilent 2100 bioanalyzer with an RNA 6000 Nano LabChip Kit. For each sample, mRNA was amplified starting from 1.5 Î¼g of totRNA by Amino Allyl MessageAmp I aRNA Kit (Ambion Inc.) to obtain amino allyl antisense RNA (aaRNA). Labeling of aaRNA was performed using NHS ester Cy3 or Cy5 dies (Amersham Biosciences, Piscataway, NJ - USA). One hybridization to Agilent 22K-gene arrays (Rat oligo array G4130A) was performed to compare quercetin supplemented cells versus unsupplemented ones. Each analysis was replicated swapping the labeling with the two cyanine dyes.

Project description:Sex pheromones rapidly affect endocrine physiology and behaviour, but little is known about their effects on gene expression in the neuroendocrine tissues that mediate olfactory processing. In this study we exposed male goldfish for 6 h to waterborne 17,20betaP (4.3 nM) and PGF2α (3 nM), the main pre-ovulatory and post-ovulatory pheromones, respectively. Both treatments elevated milt volume (P = 0.001). Microarray hybridizations were used to male telencephalon samples following PGF2α treatment and identified 71 unique transcripts that were differentially expressed (q < 5%; 67 up, 4 down). Functional annotation of these regulated genes indicates that PGF2α pheromone exposure affects diverse biological processes including nervous system functions, energy metabolism, cholesterol/lipoprotein transport, translational regulation, transcription and chromatin remodelling, protein processing, cytoskeletal organization, and signalling. By using real-time RT-PCR, we further validated three candidate genes, ependymin-II, calmodulin-A and aldolase C, which exhibited 3 - 5 fold increase in expression following PGF2α exposure. Expression levels of some other genes that are thought to be important for reproduction were also determined using real-time RT-PCR. Expression of sGnRH was increased by PGF2α, but not 17,20betaP, whereas cGnRH expression was increased by 17,20betaP but not PGF2α. In contrast, both pheromones increase the expression of glutamate (GluR2a, NR2A) and gamma-aminobutyric acid (GABAA gamma2) receptor subunit mRNAs. This gene expression data link milt release and rapid modulation of neuronal transcription as part of the response to female sex pheromones. A total of four microarray slides were hybridized to study the effects of PGF2α on gene expression in the telencephalon. Control samples (N = 4) were pooled to form our reference or technical replicates while treatment samples (N = 4), which formed our biological replicates, were ran separately. In addition, two dye swaps were performed for our biological samples for the treatments.
