Description
The polyadenosine RNA binding proteins (Pabs) represent one class of RNA binding proteins that play critical roles in gene expression. This class includes the well-studied nuclear and cytoplasmic Pabs, PABPN1 and PABPC1, respectively, as well as the newly characterized nuclear Pab, zinc finger CCCH-type containing #14, or ZC3H14. ZC3H14 was recently linked to a form of intellectual disability, suggesting a critical role for ZC3H14 in neurons; however, the post-transcriptional function of ZC3H14 is unknown. In this study, we performed a microarray analysis of cells depleted of ZC3H14 or PABPN1 in MCF-7 breast cancer cells. These results revealed that PABPN1 significantly affected ~17% of expressed transcripts as compared to ZC3H14, which affected ~1% of expressed transcripts, suggesting that ZC3H14 has specific mRNA targets. The differentially expressed mRNAs identified in this analysis not only provide information about the classes and types of transcripts that are regulated by these proteins, but also represent a set of transcripts that could be directly bound by ZC3H14 and/or PABPN1.

Description
We isolated mutants in Arabidopsis with enhanced ambient temperature response. Microarray analysis was performed to understand the extent to which ambient temperature transcriptome is perturbed in the mutants in comparison with the WT at non inductive 12 C and after shift to inductive 27 C for 2 h and 24 h.

Description
Most FDA approved drugs are not equally effective in all patients, suggesting that identification of biomarkers to predict responders to a chemoprevention agent will be needed to stratify patients and achieve maximum benefit. The goal of this study was to investigate both patient specific and cell-context specific heterogeneity of metformin response, using cancer cell lines fibroblast cell lines and induced pluripotent stem cells differentiated into lung epithelial lineages.

Description
Ablation of the mouse gene for Onecut-2 was reported previously, but characterization of the resulting knockout mice was focused on in utero development, principally embryonic development of liver and pancreas. Here, we examine postnatal development of these Onecut-2 knockout mice, especially the critical period prior to weaning. Microarray technology was used to determine the effect of Onecut-2 ablation on gene expression in duodenum, whose epithelium has among the highest levels of Onecut-2. A subset of intestinally expressed genes showed dramatically altered patterns of expression. Many of these genes encode proteins associated with the epithelial membrane, including many involved in transport and metabolism. Previously, we reported that Onecut-2 was critical to temporal regulation of the adenosine deaminase gene in duodenum. Many of the genes with altered patterns of expression in the Onecut-2 knockout mouse duodenum displayed changes in the timing of gene expression.

Description
Cumulus cells and mural granulosa cells (MGCs) are spatially and functionally distinct cell types in antral follicles: cumulus cells contact the oocyte and most MGCs contact the basal lamina. For transcriptomic analyses, both cell types were collected from small and large antral follicles, before and after stimulation of immature mice with eCG, respectively. Both cell types underwent dramatic transcriptomic changes and the differences between them became greater with follicular growth. Although cumulus cells of both stages of follicular development are competent to undergo expansion in vitro, they were otherwise remarkably dissimilar with transcriptomic changes quantitatively equivalent to those of MGCs. Gene Ontology (GO) analysis showed that cumulus cells of small follicles were enriched in transcripts generally associated with catalytic components of metabolic processes while those from large follicles were involved in regulation of metabolism, cell differentiation, and adhesion. Upon contrasting cumulus cells versus MGCs, cumulus cells were enriched in transcripts associated with metabolism and cell proliferation while MGCs were enriched for transcripts involved in cell signaling and differentiation.

Description
The bundle sheath cells (BSCs) layer a presumed control point for radial transport of water and solutes between the vasculature and the leaf mesophyll cells (MCs) is still largely understudied. Using isolated protoplasts, we found that 45% of the 90 genes differentially expressed in BSCs vs. MCs are membrane related and 20% are transport related, suggesting unique functionality of membrane transport in the BSCs, supported also by functional assays (electrophysiology and fluorescence imaging).

Description
Diabetic Neuropathy (DN) is a common complication of diabetes. Currently, there is no drug treatment to prevent or slow the development of DN. Rosiglitazone (Rosi) is a potent insulin sensitizer and may also slow the development of DN by a mechanism independent of its effect on hyperglycemia. A two by two design was used to test the effect of Rosi treatment on the development of DN. Streptozotocin-induced diabetic DBA/2J mice were treated with Rosi. DN and oxidative stress were quantified, and gene expression was profiled using the Affymetrix Mouse Genome 430 2.0 microarray platform. An informatics approach identified key regulatory elements activated by Rosi. Diabetic DBA/2J mice developed severe hyperglycemia, DN and elevated oxidative stress. Rosi treatment did not affect hyperglycemia but did reduce oxidative stress and prevented development of thermal hypoalgesia. Two novel transcription factor binding modules were identified that may control genes correlated to changes in DN following Rosi treatment: SP1F_ZBPF and EGRF_EGRF. Rosi treatment reduced oxidative stress and DN independent of its insulin sensitizing effects. Gene expression profiling identified two novel targets activated by Rosi treatment. These targets may be useful in designing drugs with the same efficacy as Rosi in treating DN but with fewer undesirable effects.
