Project description:Elucidating the developmental patterns of gene expression across brain regions is a critical step toward understanding brain development and disease. We previously studied the transcriptome of multiple brain regions and peripheral tissues across development in the vervet monkey, and identified transcripts related to hippocampal size in 59 animals across 10 developmental timepoints, ranging between 7 days to 9 years of age. Here, we extended this analysis with a focus on transcriptomic changes in hippocampus across early development in vervet neonates and infants under 1 year of age. We combined this dataset with the previously analyzed data. We identified groups of transcripts with age-related patterns, which correlated well with existing human resources. Additionally, expression quantitative trait locus (eQTL) analysis identified two further genes, RAB31 and CHMP1B, associated with hippocampal volume, refining the previously identified locus. This dataset provides unique developmental expression data in the hippocampus of a non-human primate, and expands our catalog of local and distant eQTL in this brain region.

Project description:Transcriptomic profiling is a crucial tool for understanding growth, development, behavior and predisposition to diseases and the development of health biomarkers. Here, we demonstrate the feasibility of transcriptomic assessment of cell-free fetal RNA in vervet monkey amniotic fluid supernatant (AFS).

Project description:This report is based on an ongoing study to examine gene expression differences in monkey lateral geniculate nucleus (LGN). For this study, samples from an Old World species, vervet monkey (Cercopithecus aethiops), were cross-hybridized to the Rhesus Macaque Genome Array (Affymetrix). Microarray analysis was performed using laser capture microdissected populations of individual neuronal cell bodies isolated from the LGN compared to heterogeneous samples from whole lamina. We show here that cross-species hybridization of microdissected brain tissue samples from vervet monkeys to the Rhesus array produced reliable and biologically relevant data sets. We present the first list of genes enriched in the large neuronal cell bodies of the LGN. We found that these cell bodies are concentrated with genes involved in metabolic processes and protein synthesis, whereas signaling molecules including chemokines and integrins were expressed at higher levels within heterogeneous samples. Our data set provides support for a contribution of Wnt signaling in adult monkey LGN. Keywords: gene expression profile

Project description:DNA methylation data from vervet cerebral cortex, blood, and liver using highly conserved mammalian CpGs represented on the mammalian methylation array (HorvathMammalMethylChip40). We selected a total of 240 samples representing the entire vervet lifespan, from neonatal to senile stages: 144 samples from the peripheral blood, 48 samples from the liver, and 48 samples from the cortical brain area BA10.

Project description:The limbus is a unique anatomic structure that is highly innervated and vascularized yet sets the boundary for the avascularized cornea. The corneal epithelial stem cells are believed to reside at the limbus. The intrinsic and external molecular signals that modulate the differentiation and proliferation of the limbal stems cells are still largely unidentified because of a lack of known specific markers. In this study, we used microarray technology to identify the unique gene expression profile in the limbus by comparing directly to that of its immediate adjacent structures, the cornea and conjunctiva, in the vervet monkey (Chlorocebus aethiops sabaeus). Many new genes were found to be preferentially expressed in the limbus, and two new biological pathways, melanin metabolism and apoptosis, were among other previously known processes identified in the limbus. These findings may shed light on the molecular components of limbal stem cells and their niche. Keywords: transcription profiling, gene expression

Project description:Alcohol preferring vervet dams were permitted to ingest alcohol 4 days/week during the second half of gestation (e90-e165) and paired with sucrose matched controls. Cases and controls were sacrificed with subsequent hippocampal extraction at 5 months and 2 years. RNA was extracted according to the manufacturer's protocol and hybridized to the Affymetrix Rhesus Genechip microarray. We sought to identify pathways and genes involved in the development of fetal alcohol spectrum disorder in a non-human primate in order to develop an understanding of how this disorder may develop in humans.

Project description:Alcohol preferring vervet dams were permitted to ingest alcohol 4 days/week during the second half of gestation (e90-e165) and paired with sucrose matched controls. Cases and controls were sacrificed with subsequent hippocampal extraction at 5 months and 2 years. RNA was extracted according to the manufacturer's protocol and hybridized to the Affymetrix Rhesus Genechip microarray. We sought to identify whether global downregulation in mRNA dataset was related to miRNA expression in a non-human primate model of FASD in order to develop an understanding of how this disorder may develop in humans.

Project description:To identify genes involved in responses to psychosocial stressor, we analysed RNAseq transcriptomic profiles in whole blood of 15 juvenile male vervet monkeys from the Caribbean island of St. Kitts at three experimental time points: day 0 (baseline), day 3 and day 5 of exposure to the stressor.
