Description
We used microarrays to identify differentially expressed genes. We focused on those genes that were dramatically induced (>2-fold) in WT but not in the rpp4 mutant at 2 dpi when WT and rpp4 first showed distinct phenotypes

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Mice expressing a doxycycline-inducible dominant negative BMPR2 transgene expressed only in smooth muscle are activated for one or eight weeks, and compared to transactivator-only mice also fed doxycycline. All mice are 12 weeks of old at sacrifice.
Publication Title
Molecular effects of loss of BMPR2 signaling in smooth muscle in a transgenic mouse model of PAH.

Description
The fields of drug discovery and regenerative medicine require large numbers of adult human primary hepatocytes. For this purpose, it is desirable to use hepatocyte-like cells (HLCs) differentiated from human pluripotent stem cells. To develop an efficient HLCs induction method, we constructed a red fluorescent reporter, CYP3A7R, in which DsRed is placed under the transcriptional regulation of CYP3A7 coding for a human fetus-type P450 enzyme. We created transgenic mice using mouse embryonic stem cells (mESCs) carrying a CYP3A7R transgene.
Publication Title
Real-time fluorometric evaluation of hepatoblast proliferation in vivo and in vitro using the expression of CYP3A7 coding for human fetus-specific P450.

Description
To elucidate the fundamental molecular mechanisms responsible for multistep hepatotumorigenesis, this study investigated genes that were upregulated in a stepwise manner from the nave liver condition through to chronic oxidative stress-induced hepatitis and liver tumor by time-series microarray analysis. The time-dependent gene expression profile should reflect the multistep process of hepatotumorigenesis, and might identify genes that function specifically in hepatotumorigenesis.
Publication Title
IQGAP1 and vimentin are key regulator genes in naturally occurring hepatotumorigenesis induced by oxidative stress.

Description
6-8 week old BL6, FVB/N and SV129 mouse strains were kept in normoxia or hypobaric hypoxia for 4 weeks and then phenotyped by echocardiogram and right ventricular heart catheterization, followed by tissue collection. In addition, Affymetrix expression analysis was conducted in a paired fashion.

Description
Redox Responsive Transcription Factor1 (RRTF1) in Arabidopsis is rapidly and transiently upregulated by H202, as well as biotic and abiotic induced redox signals. Inactivation of RRTF1 restricts and overexpression promotes reactive oxygen species (ROS) accumulation in response to stress. Overexpressor (oe) lines are impaired in root and shoot development, light sensitive and susceptible to Alternaria brassicae infection. These symptoms are diminished by the beneficial root endophyte Piriformospora indica which reduces ROS accumulation locally in roots and systemically in shoots, and by antioxidants and ROS inhibitors which scavenge ROS. More than 850 stress-, redox-, ROS regulated-, ROS scavenging-, defense-, cell death- and senescence-related genes are regulated by RRTF1, ~ 30% of them have ROS related functions. Bioinformatic analyses and in vitro DNA binding assays demonstrate that RRTF1 binds to GCC-box and GCC-box like sequences in the promoter of RRTF1-responsive genes. Upregulation of RRTF1 by stress stimuli as well as H2O2 requires WRKY18/40/60. RRTF1 is co-regulated with the phylogenetically related RAP2.6, which contains GCC-box like sequene in its promoter, but RAP2.6 oe lines do not accumulate higher ROS levels. RRTF1 stimulates systemic ROS accumulation in distal non-stressed leaves. We conclude that the highly conserved RRTF1 rapidly, transiently and systemically induce ROS accumulation in response to ROS and ROS-producing abiotic and biotic stress signals. Necrotrophs stimulate RRTF1 expression, while symbiotic interactions of Arabidopsis with (hemi)-biotrophs and P. indica do not affect or repress RRTF1 expression.
