Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
Arabidopsis MPK4 is involved in the control of antagonism between salicylic acid (SA) and ethylene (ET)/jasmonic acid (JA) pathways in the plant innate immune system as a repressor of the SA pathway, but an activator of the ET/JA pathway. Here we and use comparative microarray analysis of ctr1, ctr1/mpk4, mpk4 and wild type to show that MPK4 is required for only a narrow subset of ET regulated genes.
Publication Title
Arabidopsis systemic immunity uses conserved defense signaling pathways and is mediated by jasmonates.

- Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
Resistance formation is one of the major hurdles in cancer therapy. Metronomic anti-angiogenic treatment of xenografted prostate cancer tumors in SCID mice with cyclophosphamide (CPA) results in the appearance of resistant tumors. To investigate the complex molecular changes occurring during resistance formation, we performed a comprehensive gene expression analysis of the resistant tumors in vivo. We observed a multitude of differentially expressed genes, e.g., PASD1, ANXA3, NTS or PLAT, when comparing resistant to in vivo passaged tumor samples. Furthermore, tumor cells from in vivo and in vitro conditions showed a significant difference in target gene expression. We assigned the differentially expressed genes to functional pathways like axon guidance, steroid biosynthesis and complement and coagulation cascades. Most of the genes were involved in anti-coagulation, indicating its possible importance. Upregulation of anti-coagulatory ANXA3 and PLAT and downregulation of PLAT inhibitor SERPINA were validated by qPCR. In contrast, coagulation factor F3 was upregulated, accompanied by the expression of an altered gene product. These findings give insights into the resistance mechanisms of metronomical CPA treatment suggesting an important role of anti-coagulation in resistance formation.

- Affymetrix Rat Expression 230A Array (rae230a)
Description
Male Wistar rats weighing 90-120 g were acclimatized for one week and fed standard laboratory chow, at which time the animals were divided into two groups. Animals were then pair-fed for 8 weeks a regular laboratory chow and water ad libitum or Lieber-DeCarli diet (36% calories from ethanol). Control animals received the iso-caloric amount of dextrose to replace ethanol. After 8 weeks of differential feeding rats were euthanized, the pancreas immediately dissected and stored at -80?C until RNA isolation. RNA expression was analyzed using Affymetrix RAE230A gene chips

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
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.
