Project description:We isolated total RNA from staged embryos at 2 hour intervals over a 24 h period. Total RNA from 8 h embryos was used as a reference for the time course. This expression study used a >16,000 oligonucleotide (65-mers) probe set from Compugen to examine changes in gene expression in wild-type Danio rerio during development, emphasizing the period of segmentation, when the nervous system is forming. Embryos were provided by Scientific Hatcheries.
Project description:This SuperSeries is composed of the following subset Series: GSE23916: Diurnal Regulation of Gene Expression in Immature Ear Over a 72-Hour Period GSE23917: Diurnal Regulation of Gene Expression in Leaves Over a 72-Hour Period Refer to individual Series
Project description:RNA-Seq of spontaneous melanoma in Xiphophorus interspecies hybrids, and paired normal skin samples from the same melanoma-bearing animals were performed.
Project description:Circadian control of gene expression has been established in plants at the transcriptional level, but relatively little is known about circadian control of translation. We used polysome profiling to characterize regulation of transcription and translation over a 24-hour diurnal cycle in Arabidopsis, both in wild type and in plants with a disrupted clock due to constitutive overexpression of the CIRCADIAN CLOCK ASSOCIATED 1 gene (CCA1-ox, AGI AT2G46830).

Project description:Our objective was to identify candidate genes that contribute to the long 31-hour circadian period previously observed in DGRP_892. We performed transcriptional profiling of whole fly heads from two genotypes: DGRP_892, and Canton-S B, a line with a normal 24-hour circadian period. We collected fly heads every two hours over a 24-hour period. We quantified differential expression among genotype, time, and sex.
