Affymetrix Mouse Gene 2.0 ST Array (mogene20st)
Description
Mice wild type or knocked-out for the MyD88 gene specifically in liver, were recruited for this expression profiling experiment. Each group of mice (WT versus LKO) were fed with a control diet or a high fat diet. Then mice were sacrificed and liver samples form were processed for RNA extraction. Total liver RNA of each sample was then pooled with those of the same group and treatment for microarray hybridization.

Description
Puberty is a special transition period in sexual maturation, and it has been extensively studied in vertebrates in the past decades. In mammals, the initiation of puberty involves activation of numerous genes; however, there have been few comprehensive reports in small model teleosts such as the zebrafish. In the zebrafish, the onset of puberty in females is marked by the appearance of the first wave of pre-vitellogenic (PV) follicles in the ovary during sexual maturation. Using transcriptomics and real-time qPCR, this study was undertaken to investigate temporal gene expression differences between the primary growth (PG) follicles and pre-vitellogenic (PV) follicles, with particular emphasis on oocyte and follicular cell specific genes as well as several closely associated signaling pathways. Our results showed that totally 1082 genes were significantly upregulated and 530 evidently downregulated during the PG-PV transition, and among them were some well recognized biomarkers such as cyp19a1a, fshr, inha and inhbaa and some novel genes like notch3, amh, gadd45ga and lpl. Further gene ontology analysis showed that egg coat formation and steroid hormone mediated signaling pathway might be critical for follicle activation from PG to PV stage. In addition, KEGG identified several signaling pathways that might play pivotal roles in early folliculogenesis, including phosphatidylinositol signaling system, glycolsaminoglycan biosynthesis, RNA transport, and p53 signaling pathways. Overall, this study reported a comprehensive analysis for biomarker genes and potential pathways involved in PG-PV transition or follicle activation, which also marks female puberty onset in the zebrafish when occurring for the first time in sexual maturation.

Description
Identification of intrathymic Eomes+ natural Th1 cells creates a novel idea that there is more than one way for the generation of innate CD4 T cells. To more deeply characterize this type of innate T cells, we compared the gene expression profile between nTh1 cells generated in CIITAtg mice and classic Th1 cells differentiated from naive CD4 T cells in Th1-polarizing condition.

Description
Terahertz (THz) technology has emerged for biomedical applications such as scanning, molecular spectroscopy, and medical imaging. However, the biological effect of THz radiation is not fully understood. Non-thermal effects of THz radiation were investigated by applying a femtosecond-terahertz (fs-THz) pulse to mouse skin. Analysis of the genome-wide expression profile in fs-THz-irradiated skin indicated that wound responses were predominantly through NFB1- and Smad3/4-mediated transcriptional activation. Repeated fs-THz radiation delayed the closure of mouse skin punch wounds due to up-regulation of transforming growth factor-beta (TGF-). These findings suggest that fs-THz radiation provokes a wound-like signal in skin with increased expression of TGF- and activation of its downstream target genes, which perturbs the wound healing process in vivo.

Description
Ovarian clear cell carcinoma (OCCC) is an aggressive form of ovarian cancer with high ARID1A mutation rates. Here we present a genetically engineered mouse model of OCCC. We find that ARID1A inactivation is not sufficient for tumor formation, but requires concurrent activation of the phosphoinositide 3-kinase catalytic subunit, PIK3CA. Remarkably, the mice develop highly penetrant tumors with OCCC-like histopathology, culminating in hemorrhagic ascites and a median survival period of 7.5 weeks. Therapeutic treatment with the pan-PI3K inhibitor, BKM120, prolonged mouse survival by inhibiting tumor cell growth. Cross-species gene expression comparisons support a role for IL-6 inflammatory cytokine signaling in OCCC pathogenesis. We further show that ARID1A-PIK3CA mutations cooperate to promote tumor growth through sustained IL-6 overproduction. Our findings establish an epistatic relationship between SWI/SNF chromatin remodeling and PI3K pathway mutations in OCCC and demonstrate that these pathways converge on pro-tumorigenic cytokine signaling. We propose that ARID1A protects against inflammation-driven tumorigenesis.
