Affymetrix Rat Expression 230A Array (rae230a)
Description
The rat uterus responds to acute estrogen treatment with a series of well characterized physiological responses; however, the gene expression changes required to elicit these responses have not been fully characterized. In order to understand early events induced by estrogen exposure in vivo, we evaluated the temporal gene expression in the uterus of the immature rat after a single dose of 17 Alpha-ethynyl estradiol (EE) by microarray analysis, evaluating the expression of 15,923 genes. Immature 20 day old rats were exposed to a single dose of EE (10 ug/kg) and the effect on uterine histology, weight and gene expression were determined after 1, 2, 8, 24, 48, 72 and 96 h. EE induced changes in the expression of 3,867 genes, at least at one time point (p¡Ü0.0001), and at least 1.5 fold (up- or down-regulated). Specifically, the expression of 8, 116, 3030, 2076, 381, 445, and 125 genes was modified at 1, 2, 8, 24, 48, 72 or 96 hours after exposure to EE respectively (p¡Ü0.0001, t Test). At the tissue and organ level, a clear uterotrophic response was elicited by EE after only 8 h, reaching a maximum after 24 h and remaining detectable even after 96 h of exposure. The uterine phenotypic changes were induced by sequential changes in the transcriptional status of a large number of genes, in a program that involves multiple molecular pathways. Using the gene ontology to better understand the temporal response to estrogen exposure, we determined that the earliest changes were in the expression of genes whose products are involved in transcriptional regulation and signal transduction, followed by genes implicated in protein synthesis, energy utilization, solute transport, cell proliferation and differentiation, tissue remodeling and immunological responses among other pathways. The compendium of genes here presented represents a comprehensive compilation of estrogen-responsive genes involved in the uterotrophic response.

Description
In the terms of vaccine efficacy and duration of protection in malaria vaccination is major concern against malaria. On the other hand, it is facing complications in development and administration to the host. However, whole sporozoites vaccination (WSV) is far more efficacious than any other alternative strategy. We have found that the intermittent sporozoite challenge to immune mice following RAS vaccination extends the longevity of sterile protection by maintaining CD8+T cell memory responses to LS infection and also helps in CD8a+DCs accumulation and activation in liver. Consequently, there has been great interest in elucidating and understating the sterile immunological response at mechanistic level. The information we have generated can then potentially be used in generation of next generation vaccine with improved efficacy and duration of protection. In this work, to elucidate the host initial immune response underlying the protective effects of a WSV in shaping the protected sterile protection and advances its immunogenicity in the future, a high-throughput RNA sequencing technology was used to investigate the immunization related gene expression patterns of mouse immunized with radiation attenuated sporozoites (RAS) vaccine.

Description
Introduction: The Plant Organelle RNA Recognition (PORR) domain proteins are nucleus-encoded RNA-binding proteins that have acquired specific roles in organelle RNA metabolism as splicing factors of chloroplast group II introns. LEFKOTHEA (At5g62990) is a nuclear gene encoding a PORR domain protein that carries a transit peptide (TP) and monopartite or bipartite nuclear localization signals (NLS). These motifs result in dual-targeting of LEFKOTHEA to the nucleus and chloroplasts implying a role in the splicing of chloroplast group II introns and nuclear pre-mRNA introns. Therefore, we examined the splicing efficiency of plastid and nuclear genes in lefko2 mutant.Methods: The lefko2 mutant was isolated from a genetic screen of an M2 EMS-mutagenized Arabidopsis thaliana Columbia (Col-0) background seed population. The lefko2 mutant allele has a white cotyledon phenotype caused by a G to A mutation in the coding region resulting in a Glycine (G) 373 to Aspartic acid (D) conversion. Total RNA was extracted using plant RNA kit spin columns with an on-column DNase treatment from lefko2 mutant and wild-type Arabidopsis cotyledons. The quantity and integrity of the RNA was assessed using a NanoDrop 1000 spectrophotometer and agarose gel electrophoresis. RNA-seq libraries were generated using the TruSeq Low Input kit according to the manufacturer's instructions (Illumina). Sequencing was performed on an Illumina HiSeq 2000 instrument at BGI (Beijing Genomics Institute). Raw reads were filtered into clean reads and aligned to the Arabidopsis genome (TAIR10). RNA-seq data were analyzed using the SOAP (Release 2.121) with parameters “-s 40 -l 32 -v 3 -r 2” and the TopHat/Cufflinks pipeline (version 2) with parameters “-p 16 --solexa1.3-quals --segment-length 30 --segment-mismatches 2 -r 20 --mate-std-dev 20 --library-type fr-unstranded”. We generated 480 million paired-end reads (101 bp in length) for each sample. On average, about 90% of these reads could be unambiguously aligned to the TAIR10 reference genome sequence. Alternative splicing events were detected for lefko2 and wild-type using Spladder. Intron retention events detected in wild-type were filtered out from lefko2 or vice-versa, and visualized using the Integrative Genomics Viewer (IGV) tool.Results: Splicing defects were observed in numerous nuclear genes of lefko2 cotyledons compared to wild type. Among them, intron retention (IR) events were the most prominent. Further, the fidelity of 5' splice site (5'SS) donor and 3'SS acceptor splicing was disturbed in lefko2 cotyledons. To less extend, exon skipping (ES) defects were also detected.Conclusions: Detailed nuclear splicing events were widely observed in lefko2 cotyledons demonstrating a prevalent role of LEFKOTHEA in the splicing of nuclear pre-mRNA introns.Overall design: RNA-seq libraries were generated using the TruSeq Low Input kit according to the manufacturer's instructions (Illumina). Sequencing was performed on an Illumina HiSeq 2500 instrument at BGI (Beijing Genomics Institute).

Description
This study aimed to identify the genetic signatures associated with disease prognosis in bladder cancer. We used 165 primary bladder cancer samples, 23 recurrent non-muscle invasive tumor tissues, 58 normal looking bladder mucosae surrounding cancer and 10 normal bladder mucosae for microarray analysis. Hierarchical clustering was used to stratify the prognosis-related gene classifiers. For validation, real-time reverse-transcriptase polymerase chain reaction (RT-PCR) of top-ranked 14 genes was performed. On unsupervised hierarchical clustering using prognosis related gene-classifier, tumors were divided into 2 groups. The high risk gene signatures had significantly poor prognosis compared to low risk gene signatures (P<0.001 by the log-rank test, respectively). The prognosis-related gene classifiers correlated significantly with recurrence of non-muscle invasive bladder cancer (hazard ratio, 4.09; 95% confidence interval [CI], 1.94 to 8.64; P<0.001), and progression (hazard ratio, 23.68; 95% confidence interval [CI], 4.91 to 114.30; P<0.001), cancer-specific survival (hazard ratio, 29.25; 95% confidence interval [CI], 3.47 to 246.98; P=0.002) and overall survival (hazard ratio, 23.33; 95% confidence interval [CI], 4.97 to 109.50; P<0.001) of muscle invasive bladder cancer (p < 0.001, respectively). No patient with non-muscle invasive bladder cancer experienced cancer progression in low risk gene signature group. Prognosis-related gene classifiers validated by RT- PCR showed identical results. Prognosis related gene-classifiers provided strong predictive value for disease outcome. These gene classifiers could assist in selecting patients who might benefit from more aggressive therapeutic intervention or surveillance.
