Description
Dramatic changes of gene expressions are known to occur in human endometrial stromal cells (ESC) during decidualization. The changes in gene expression are associated with changes of chromatin structure, which are regulated by epigenetic mechanisms such as histone modifications. Here, we investigated genome-wide changes in histone modifications and mRNA expressions associated with decidualization in human ESC using chromatin immunoprecipitation (ChIP) combined with next-generation sequencing. ESC were incubated with estradiol and medroxyprogesterone acetate for 14 days to induce decidualization. The ChIP-sequence data showed that induction of decidualization increased H3K27ac and H3K4me3 signals in many genomic regions but decreased in only a few regions. Most (80%) of the H3K27ac-increased regions and half of the H3K4me3-increased regions were located in the distal promoter regions (more than 3 kb upstream or downstream of the transcription start site). RNA-sequence showed that induction of decidualization up-regulated 881 genes, 223 of which had H3K27ac- or H3K4me3-increased regions in the proximal and distal promoter regions. Induction of decidualization increased the mRNA levels of these genes more than it increased the mRNA levels of genes without H3K27ac- or H3K4me3-increased regions. Pathway analysis revealed that up-regulated genes with the H3K27ac- or H3K4me3-increased regions were associated with insulin signaling. These results show that histone modification statuses genome-widely change in human ESC by induction of decidualization. The main changes of histone modifications are increases of H3K27ac and H3K4me3 in both the proximal and distal promoter regions, which are involved in the up-regulation of gene expression that occurs during decidualization. Overall design: mRNA profiles of human endometrial stromal cells with and without EP inductions for 2 individuals. (EP induction: induction with estradiol (10-8 M) and medroxyprogesterone acetate (10-6 M))

Description
We explored the mechanism by which TLP affects DNA damage response. We performed mRNA-seq analysis of non-treated and etoposide-treated samples in control and TLP-knockdown cells. We show that TLP is critical for global transcriptional repression after double-strand DNA breaks (DSBs). Overall design: Examination of non-treated and etoposide-treated samples in control and TLP-knockdown cells

- Affymetrix Soybean Genome Array (soybean)
Description
Gene expression profiles in soybean seeds at 4 developmental stages, pod, bean 2 mm, bean 5 mm, and full-sized bean, were examined by DNA microarray analysis. Total genes of each samples were classified into 4 clusters according to developmental stages. Differentially expressed genes (DEGs) were extracted by comparing their expression in two adjacent stages, by using the rank product method.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
ICR-derived glomerulonephritis (ICGN) mice is a novel inbred strain of mice with a hereditary nephrotic syndrome. Deletion mutation of tensin 2 (Tns2), a focal adhesion molecule, has been suggested to be responsible for nephrotic syndrome in ICGN mice, however, existence of other associative factors has been suggested. To identify additional associative factors and to better understand onset mechanism of nephrotic syndrome in ICGN mice, comprehensive gene expression analysis using DNA microarray was conducted. Immune-related pathways were markedly altered in ICGN mice kidney as compared with ICR mice. Furthermore, gene expression level of complement component 1, s subcomponent (C1s), whose human homologue has been reported to associate with lupus nephritis, was markedly low in ICGN mice kidney.

Description
Human and rat umbilical cord matrix mesenchymal stem cells (UCMSC) possess the ability to control the growth of breast carcinoma cells. Comparative analyses of two types of UCMSC suggest that rat UCMSC-dependent growth regulation is significantly stronger than that of human UCMSC. Their different tumoricidal abilities were clarified by analyzing gene expression profiles in the two types of UCMSC. Microarray analysis revealed differential gene expression between untreated nave UCMSC and those co-cultured with species-matched breast carcinoma cells. The analyses screened 17 differentially expressed genes that are commonly detected in both human and rat UCMSC. The comparison between the two sets of gene expression profiles identified two tumor suppressor genes, adipose-differentiation related protein (ADRP) and follistatin (FST), that were specifically up-regulated in rat UCMSC, but down-regulated in human UCMSC when they were co-cultured with the corresponding species' breast carcinoma cells. Over-expression of FST, but not ADRP, in human UCMSC enhanced their ability to suppress the growth of MDA-231 cells. The growth of MDA-231 cells was also significantly lower when they were cultured in medium conditioned with FST, but not ADRP over-expressing human UCMSC. In the breast carcinoma lung metastasis model generated with MDA-231 cells, systemic treatment with FST-overexpressing human UCMSC significantly attenuated the tumor burden. These results suggest that FST may play an important role in exhibiting stronger tumoricidal ability in rat UCMSC than human UCMSC and also implies that human UCMSC can be transformed into stronger tumoricidal cells by enhancing tumor suppressor gene expression.
