Project description:The Affymetrix GeneChip Mu11K was used to analyze the gene expression profile in developing mouse cerebellum (two GeneChips per E18, P7, P14, P21, and P56) to assist in the understanding of the genetic basis of cerebellar development in mice. The analysis showed 81.6% (10,321/12,654) of the genes represented on the GeneChip were expressed in the postnatal cerebellum, and among those, 8.7% (897/10,321) were differentially expressed with more than a two-fold change in their maximum and minimum expression levels during the developmental time course. The expression data (mean signal in relative unit) of all of these 897 differentially expressed genes were listed in GSM50(for E18), GSM51(for P7), GSM52(for P14), GSM53(for P21), and GSM54(for P56) as well as our homepage at http://www.brain.riken.go.jp/labs/lm Keywords = mouse cerebellum development

Project description:Developmental differences in gene expression in the postnatal mouse cochlear nucleus was analyzed at two or three ages using two different array platforms, the Affymetrix Mouse 430A GeneChip or the NIA 15K mouse cDNA microarray. These ages, P7, P14, and P21 parallel a critical period of neuron survival dependent on input from the auditory nerve. Keywords: parallel sample

Project description:INTRODUCTION AND OBJECTIVE: Obstruction and other processes that lead to renal damage can have different effects in adult versus developing kidneys. These differences are important for understanding pathophysiology, but also could influence selection of biomarkers used for detection of renal damage that could be used to guide intervention. In mice, significant renal development occurs postnatally, providing a model for understanding kidney development. To date, gene expression changes that occur mouse kidney growth and development postnatally have been poorly characterized. We describe here a comprehensive gene expression of the developing mouse kidney based on microarray profiling. METHODS: C57BL/6 mice were sacrificed and kidneys were harvested at embryonic day E19.5, and postnatal days P1, P3, P5, P7, P10, P14, P21, P28 and P35. RNA was extracted from kidneys and transcript profiling was performed using Agilent microarrays. Transcripts that undergo abrupt transitions in expression level over the time course were identified using StepMiner analysis (Sahoo, 2007). Ingenuity pathway analysis (IPA) was used to analyze the biological function and gene networks of gene expression data. RESULTS: Transcript levels for 13645 probes (representing 12769 genes) were modulated significantly over the time course, with 6949 up-regulated and 6696 down-regulated. IPA was used to identify genetic pathways, networks and functions significantly altered over the time course. Interestingly, in days P10 to P14 gene functions significantly altered were up-regulated exclusively with the functions represented including lipid metabolism, small molecule biochemistry and molecular transport. Between days P5 to P7 down-regulated genes predominated with enriched functions including, gene expression, cell cycle, protein synthesis and embryonic development. For P14 to P21 enriched functions included DNA replication, recombination and repair, cell cycle, tissue development, cellular assembly and organization, protein trafficking and cell morphology. In the late stages (P21 to P28) functional enrichment was seen for cell-to-cell signaling, tissue development, cellular movement. CONCLUSIONS: This study provides the most comprehensive temporal survey of postnatal kidney development to date. This data set provides a framework for interpreting nephropathies, such as those induced by congenital obstruction. time series design

Project description:The Opioid Use Disorder epidemic led to an increase in cases of Nenonatal Opioid Withdrawal Syndrome (NOWS) in infants born to opioid-dependent mothers. Hallmark features include weight loss, irritability, inconsolability, insomnia, and increased pain sensitivity. The neurobiological basis of NOWS is largely unknown. Improved mouse models will facilitate mechanistic and treatment discovery. We treated neonatal outbred Cartworth Farms White (CFW) mice (Swiss Webster) with morphine sulfate (15 mg/kg, s.c.) twice daily on postnatal day (P)1 through P14, the approximate third trimester-equivalent of human gestation. Weight loss was monitored and behavioral symptoms were measured on P7 and P14 at 16 h post-morphine. Brainstem containing pons and medulla was collected on P14 and processed for transcriptome analysis via mRNA sequencing (RNA-seq). Morphine induced weight loss from P2 to P14 that remained at P21 and P50. Repeated morphine also induced a delayed self-righting latency at P4 and a persistent, female-specific delay at P14. Morphine-treated females also showed an earlier increase in ultrasonic vocalizations (USVs) on P7. Both morphine-treated sexes showed a large increase in USVs on P14. Furthermore, thermal nociception via hot plate and tail withdrawal assays indicated that mice exhibited thermal hyperalgesia on P7 and P14, with females showing greater hyperalgesia (tail withdrawal) on P7. Morphine-treated mice also exhibited anxiety-like behavior at P21 (open field). Finally, brainstem transcriptome analysis identified a canonical gene set relevant to opioid signaling in males and a distinct gene set in females that was enriched for ribosomal proteins, mitochondrial function and neurodegenerative disorders. Sex-specific transcriptomic neuroadaptations implicate sex-specific treatments.

Project description:The goal of this project is to obtain the expression pattern of miRNAs in wild type kidneys at various ages during development. The data is obtained from mouse kidneys of ages P0, P7, P14, P21 and P35. The analysis compares the expression levels of miRNAs between the age groups.

Project description:The assembly of neural circuits involves multiple sequential steps such as the specification of cell types, their migration to proper brain locations, morphological and physiological differentiation, and the formation and maturation of synaptic connections. This intricate and often prolonged process is guided by elaborate genetic mechanisms that regulate each developmental event. Evidence from numerous systems suggests that each cell type, once specified, is endowed with a genetic program that directs its subsequent development. This cell intrinsic program unfolds in respond to, and is regulated by, extrinsic signals, including cell-cell and synaptic interactions. To a large extent, the execution of this genetic program is achieved by the expression of specific sets of genes that support distinct developmental processes. Therefore, a comprehensive analysis of the developmental progression of gene expression in synaptic partners of neurons may provide a basis for exploring the genetic mechanisms regulating circuit assembly. Here we examined the developmental gene expression profiles in well defined cell types in a stereotyped microcircuit of the cerebellar cortex. Manually sorted pure populations of Purkinje cells and Stellate/Basket cells, 3 biological replicates, from Gad67-GFP bac-transgenic (G42) mice were profiled during postnatal developmental stages P3, P7, P14, P21, P28, P35 and P56 using Affymetrix MOE430.2 expression array
