Affymetrix Rat Expression 230A Array (rae230a)
Description
Aging progress is distinctly characterized by systematic and progressive decline of physiological functions with increasing age in virtually all tissues or organs. Addressing the patterns of molecular changes in different tissues and how different tissues interact with each other during aging are an important question in aging.
Publication Title
The spatial association of gene expression evolves from synchrony to asynchrony and stochasticity with age.

Description
Purpose:Acupuncture exerts cardioprotective effect on myocardial I/R injury. In order to elucidate the potential mechanisms, RNA-seq by next generation sequencing was used to identify the rat genome-wide alterations by EA at Neiguan acupoint pretreatment in this study Methods: Adult male Sprague Dawley rats (250-300g) were divided into four groups: Sham operation(SO), I/R, electro-acupuncture at Neiguan pretreatment (EA) and electro-acupuncture at non-acupoint (NA) groups and myocardium mRNA profiles of rats in each group were generated by deep sequencing,using Illumina Hiseq 2000. The sequence reads that passed quality filters were analyzed at the transcript isoform level with two methods: Burrows–Wheeler Aligner (BWA) followed by ANOVA (ANOVA) and TopHat followed by Cufflinks. Results: Using an optimized data analysis workflow, we mapped about 20~43 million sequence reads per sample to the mouse genome (UCSC RN4) and identified 26190 22895 25160 22852 transcripts in the SO, I/R, EA and NA rats with TopHat and Cufflinks workflow respectively. Approximately 32% and 22% of the transcripts showed differential expression between the SO and I/R, I/R and EA , I/R and NA, respectively with a |log2 fold change |=1. Conclusions: Our results for the first time generated genome-wide gene expression profiles both in the rat I/R model and in acupuncture treatment by high throughput sequencing. The optimized data analysis workflows reported here should provide a framework for acupuncture investigations of expression profiles. Overall design: Myocardium mRNA profiles of SO, I/R, EA and NA rats were generated by Hiseq 2000, Each group there were two samples.

Description
Metastatic colonization involves cancer cell lodgment or adherence in the microvasculature and subsequent migration of those cells across the endothelium into a secondary organ site. To study this process further, we analyzed both in vitro and in vivo migration of human PC-3 prostate cancer cells . We isolated 6 subpopulation of cells: TEM4-18 were isolated from in vitro transendothelial migration of PC-3 cells; GS672.Ug, GS683.LALN and JD1203.Lu are single passaged in vivo cell lines from TEM4-18; GS689.Li and GS694.LAd are twice passaged in vivo cell lines from PC-3 cells. All the subpopulations crossed an endothelial barrier more efficiently and more aggressive in a murine metastatic colonization model than parental PC-3 cells. Microarray and FACS analysis of these cells showed that the expression of many genes previously associated with leukocyte trafficking and cancer cell extravasation were either unchanged or down-regulated. These cells exhibited characteristic molecular markers of an epithelial-to-mesenchymal transition, including frank loss of E-cadherin expression and upregulation of the E-cadherin repressor ZEB1.

Description
Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder that is characterized by increased circulating androgen levels, anovulatory infertility, and frequently, insulin resistance and hyperinsulinemia.The abnormity of oocyte nuclear maturity is the main reason for anovulatory infertility and pregnancy loss in PCOS patients.The bidirectional exchanges between oocyte and contiguous CCs are important for oocyte competence acquisition, early embryonic development and CC expansion.Gene expression profiles of CCs has been suggested to predict embryo development and pregnancy outcome.

Description
Even though small cell lung cancer (SCLC) has entered the age of broad genomic analysis, platinum-based chemotherapy remains the standard care for SCLC. Topotecan is the only approved agent for recurrent or progressive SCLC (1). In the absence of well-defined genomic biomarkers, clinical efficacy signals in genomically distinct subsets of SCLC could have been missed. Serine/Arginine Splicing Factor 1 (SRSF1) is a member of SR protein family. The deleterious consequences of overexpression of the SRSF1 proto-oncogene in human cancers suggest that there are complex mechanisms and pathways underlying SRSF1-mediated transformation (2). Whole exome and transcriptome sequencing of primary tumor SCLC from 99 Chinese patients has identified SRSF1 DNA amplification and mRNA over-expression which predicts poor survival in Chinese SCLC patients. In vitro and in vivo studies have demonstrated that SRSF1 is essential for tumorigenecity of SCLC and plays a key role in DNA repair and chemo-sensitivity. Overall design: We did RNAseq on 79 small cell lung cancer patients'' tumor sample and 7 normal lung tissue. We normalized the RNAseq data and did differential expression analysis. The deleterious consequences of overexpression of the SRSF1 proto-oncogene in human cancers suggest that there are complex mechanisms and pathways underlying SRSF1-mediated transformation.
