Description
Premature progesterone (P) rise during GnRH antagonist cycles for IVF is a frequent phenomenon and has been associated with lower pregnancy and implantation rates. Different thresholds of progesterone have been used so far to define its premature rise during the follicular phase of an IVF stimulated cycle. In this study, we evaluated endometrial gene expression on the day of oocyte retrieval according to the level of serum progesterone on the day of hCG administration in GnRH antagonist cycles.Endometrial biopsies from eleven patients were taken with a Pipelle de Cornier (Prodimed, Neuilly-en-Thelle, France) on the day of oocyte retrieval in a GnRH antagonist/rec-FSH stimulated IVF cycle with fresh embryo transfer. Biopsies were analysed for gene expression with Affymetrix Human Genome (HG) U133 Plus 2.0 Arrays and GCOS software (Affymetrix, Santa Clara, CA, USA). Patients were divided into three different groups according to their progesterone serum concentration on the day of hCG administration (A) P <= 0.9 ng/mL, (B) 1 < P < 1.5 ng/mL, and (C) P > 1.5 ng/mL. Serum P was measured with the automated Elecsys immunoanalyser (Roche Diagnostics, Mannheim, Germany). Selected differentially expressed genes were validated with quantitative real-time PCR (QPCR) with TaqMan Gene Expression Assays (Applied Biosystems, Foster City, CA, USA).

Description
The Keap1/Nrf2 signaling pathway is a tractable target for the pharmacological prevention of tumorigenesis. 3H-1,2-dithiole-3-thione (D3T) and 1-[2-cyano-3,12-dioxooleana-1,9(11)-dien-28-oyl]imidazole (CDDO-Im) are representative members of two classes of Nrf2-activating chemopreventive agents. Natural dithiolethiones have been widely used in clinical trials for cancer chemoprevention. Synthetic triterpenoids, however, have been shown to be significantly more potent Nrf2 activators and are under clinical evaluation for the treatment of chronic kidney disease. This study seeks to characterize the structure-activity relationship between D3T and CDDO-Im in mouse liver tissue. To this end we treated Wt and Nrf2-null mice with 300 umol/kg bw D3T and 3, 10, and 30 umol/kg bw CDDO-Im every other day for 5 days and evaulated global gene expression changes as a product of both treamtent and genotype using Affymetrix microarray.

Description
The purpose of this study was to characterize the transcriptional effects induced by intramuscular IFN-beta-1a treatment (Avonex, 30 g once weekly) in patients with relapsing-remitting form of multiple sclerosis (MS). By using Affymetrix DNA microarrays, we obtained genome-wide expression profiles of peripheral blood mononuclear cells from 24 MS patients within the first four weeks of IFN-beta administration.

Description
Disseminated prostate cancer cells colonize the skeleton to progress into macroscopic lesions only if they successfully adapt to the bone microenvironment. We previously reported that the ability of prostate cancer cells to generate skeletal tumors in animal models correlated with the expression of the alpha-receptor for Platelet-Derived Growth Factor (PDGFRa). In this study we aimed to identify PDGFRa-regulated genes responsible for the acquisition of a bone-metastatic prostate phenotype. We performed genome-wide expression comparative analyses of human prostate cancer cell lines that differ for PDGFRa expression and propensity to establish tumors in the skeleton of animal models. We investigated the genes that were differentially regulated in the highly bone-metastatic PC3-ML cells and their low-metastatic counterpart PC3-N cells, and the genes differentially regulated between PC3-N and PC3-N with overexpression of PDGFRa (PC3NRa). We have previously shown that DU-145 cells lack PDGFRa and fail to survive longer than three days as disseminated tumor cells after homing to the mouse bone marrow. Interestingly, and in contrast to PC3-N cells, the exogenous expression of PDGFRa did not promote metastatic bone-tropism of DU-145 cells in our model. Thus, we examined the genes that were differentially regulated between DU-145 and DU-145(Ra) and excluded them from our candidate genes. Finally, to refine our findings and compensate for PC3 and DU-145 genetic disparity, we performed a comparative analysis of the genes differentially regulated between two bone metastatic single-cell progenies that were derived from PC3-ML cells.

Description
Transcriptional profiles of uropathogenic Escherichia coli CFT073 exposed to cranberry-derived proanthocyanidins (PACs) were determined. Our results indicate that bacteria grown on media supplemented with PACs were iron-deprived. To our knowledge, this is the first time that PACs have been shown to induce a state of iron-limitation in this bacterium.
