Transcription profiling of E12.5 mouse whole embryo, E12.5 placenta, embryonic stem (ES) cells, and trophoblast stem (TS) cells on a novel microarray design to validate the system

ABSTRACT: E12.5 mouse whole embryo, E12.5 placenta, embryonic stem (ES) cells, and trophoblast stem (TS) cells were compared on a novel microarray design to validate the system. The in situ-synthesized 60-mer oligonucleotide microarray platform contains approximately 44,000 DNA features, and was designed to detect transcripts from all known genes, as well as about 5,000 potential genes, as identified by the NIA Mouse Gene Index 2.0. Seven external RNA controls were derived from intronic and intergenic yeast genome sequences, and 60-mer probes were spotted 10 time each on the slides. These spike-in RNA controls were diluted to cover 7 orders of magnitude in initial concentration, and used to define a function relating signal intensity to transcript abundance.

Transcription profiling of E12.5 mouse whole embryos and placentas pooled within 3 litters to validate a new array

Project description:E12.5 mouse whole embryos and placentas were pooled within 3 litters and total RNA was extracted. Fluorescently-labeled, linearly-amplified cRNA targets were prepared from the RNA samples and compared on a novel microarray design to validate the system. A "dye-swapped" experimental design was used to assess the accuracy and precision of the system. The in situ-synthesized 60-mer oligonucleotide microarray platform contains approximately 22,000 DNA features, and was designed to detect transcripts from the entire NIA cDNA clone collection.

Transcript copy number estimation using a mouse whole-genome oligonucleotide microarray (22k Linearity)

Project description:E12.5 mouse whole embryo and E12.5 placenta total RNA were pooled to create 25:75, 50:50, and 75:25 ratio mixtures, based on Bioanalyzer quantitation. These samples, along with the original unmixed RNAs, were used as templates for duplicate linear amplification labeling reactions. cRNA target mixtures were hybridized against a Universal Mouse Reference (Stratagene). Pairwise comparison using the NIA Microarray Analysis (ANOVA) software produced log ratios, which were compared to the expected log ratios for genes showing statistically significant (FDR<0.05) differential expression between unmixed embryo and placenta.

Thyroid Hormone (TH) Controls The Remodeling Of The Pancreas And The Liver, Part B

Project description:Thyroid hormone (TH) controls the remodeling of the pancreas and the liver. TH-induces dedifferentiation of the exocrine pancreas to a progenitor state (Proc. Nat. Acad Sci. 105, 8962-8967 (2008)) and it remodels the endocrine pancreas (Dev. Biol. 328, 384-391 (2009)). The redifferentiated frog pancreas resembles closely the pancreas of other typical vertebrates. Two pancreas arrays were carried out. The first one studied gene expression changes at different developmental stages of Xenopus laevis during metamorphosis. The second array studies gene expression changes at varying times after the addition of TH to premetamorphic tadpoles. Keywords: co-expression design,development or differentiation design,reference design,time series design Overall design: Thyroid hormone (TH) controls remodeling of the liver. The microarray was carried out to identify changes in gene expression at different stages of development during metamorphosis. This is part 2, done on the 22K Xenopus platform version 1. This dataset was from livers of Xenopus tadpoles (NF52, NF62, and NF66). Each was made in triplicate. Samples in all 3 parts of the study received the same thyroid hormone levels.
