To investigate the evolutionary divergence of transcriptional regulation between the mouse subspecies, we performed transcriptome analysis by microarray on testes from the X-chromosome substitution strain, which carries different subspecies-derived X chromosome on the host subspecies genome. Transcription profiling showed that large-scale aberrations in gene expression were occurred on the introgressed X chromosome. This improper expression was restored by introducing chromosome 1 from the same donor strain as the X chromosome, suggesting that the genetic incompatibility between trans-acting regulatory gene(s) on chromosome 1 and X-linked downstream genes might be a cause of the misregulation.

View SamplesNucleotide polymorphisms can potentially influence the hybridization of mRNA to 25-mer oligonucleotides. Because Affymetrix Rice Genome Array was designated mainly for Nipponbare genome of Oryza sativa, the expression level of other varieties could not be estimated correctly. We tried to apply new approaches to estimate expression level by discerning the probe-level differential hybridization.

View SamplesSnail is a transcriptional repressor, which induces epithelial-mesenchymal transition. However, overall functions of Snail remain to be elucidated. This microarray was performed to investigate the influence of Snail expression on mRNA transcription levels in a lung adenocarcinoma cell line, II-18.

View SamplesWe investigated whether in vitro expansion of human alveolar epithelial type II cells is possible. We found that human endogenous human alveolar epithelial type II cells can be cultured and passaged. The culture system enabled retroviral gene transduction into human alveolar epithelial type II cells. We performed RNA sequencing of human alveolar epithelial type II cells transduced with mutant surfactant protein C or control vector. Overall design: Cultured human alveolar epithelial type II cells were transfected with retroviral vector containing mutant surfactant protein C or control retroviral vector. The retroviral vector contained LNGFR as a marker. After gene transduction, transduced cells were purified by magnetic-activated cell sorting. The transcriptome of the cells was generated by 5'Tag-seq using Ion Genestudio S5 Sequencer.
