Affymetrix Zebrafish Genome Array (zebrafish)
Description
Peptidoglycan recognition proteins (PGRPs) are a family of pattern recognition receptors (PRRs) that serve as a strong link between invertebrate and vertebrate immunity.It has been demonstrated that PGRPs in insects function as bacterial recognition molecules which trigger proteolytic or signal transduction pathways, being thus important in the antimicrobial innate immunity.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Haploid pluripotent stem cells, such as haploid embryonic stem cells (haESCs), facilitate the genetic study of recessive traits. In vitro, fish haESCs maintain haploidy in both undifferentiated and differentiated states, but whether mammalian haESCs can preserve pluripotency in the haploid state has not been tested. Here, we report that mouse haESCs can differentiate in vitro into haploid epiblast stem cells (haEpiSCs), which maintain an intact haploid genome, unlimited self-renewal potential, and durable pluripotency to differentiate into various tissues in vitro and in vivo. Mechanistically, the maintenance of self-renewal potential depends on the Activin/bFGF pathway. We further show that haEpiSCs can differentiate in vitro into haploid progenitor-like cells.

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
In plants, CCCH zinc finger proteins involved in secondary wall formation and anther development are poorly understood. We have functionally identified two homologous genes C3H14 and C3H15 and found that the two genes differentially regulate secondary wall formation and anther development. C3H14 contributes more to secondary wall thickening, whereas, C3H15 is more important for anther development.
Publication Title
Arabidopsis C3H14 and C3H15 have overlapping roles in the regulation of secondary wall thickening and anther development.

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
The C-REPEAT-BINDING FACTOR (CBF) pathway has important roles in plant responses to cold stress. Previous research documented that constitutively expressed upstream transcription factors are activated by cold stress to induce the expression of CBF genes and the resulting CBF proteins trigger the expression of downstream cold responsive genes that confer freezing tolerance. In the present study, we found that dysfunction of RNA-DIRECTED DNA METHYLATION 4 (RDM4), which encodes a protein that associates with RNA polymerases Pol IV and Pol V as well as Pol II, and is required for RNA-directed DNA methylation (RdDM) and proper plant development in Arabidopsis, reduced chilling and freezing tolerance in Arabidopsis as evidenced by decreased survival and increased electrolyte leakage under cold stress conditions. CBFs and CBF regulon genes were down-regulated in rdm4 but not nrpe1 (the largest subunit of PolV) mutant plants, suggesting that the role of RDM4 in cold stress responses is independent of the RdDM pathway. Overexpression of RDM4 increased the expression of CBFs and CBF regulon genes and decreased cold-induced membrane injury. The rdm4 mutants exhibited decreased antioxidant enzyme activities and increased accumulation of reactive oxygen species. Microarray analysis indicated that a great proportion of genes affected by rdm4 overlapped with those affected by CBF2 and CBF3 in Arabidopsis. Chromatin immunoprecipitation (ChIP) results suggested that RDM4 is important for Pol II occupancy at the promoters of CBF genes but not the promoters of up-stream regulators of CBFs. Together, these data indicate that RDM4 acts as a component of a Pol II transcription complex that regulates CBF gene expression and cold stress resistance in Arabidopsis.

- Affymetrix Vitis vinifera (Grape) Genome Array (vitisvinifera)
Description
Solar ultraviolet CUV-Cradiation reaching the Earths surface is little due to the filtering effects of the stratospheric ozone layer. At present, artificial UV-C irradiation is utilized for different biological processes. Grape is a major fruit crop around the world. Research has shown that UV-C irradiation induced the biosynthesis of phenols. However, changes at the molecular level in response to UV-C and leading to these effects are poorly understood. To elucidate the effect of UV-C on expression of genes in grape and the response mechanism, transcript abundance of grape (Vitis vinifera L.) leaves was quantified using the Affymetrix Grape Genome oligonucleotide microarray (15,700 transcripts)

Transcriptomic analysis of grape (Vitis vinifera L.) leaves after exposure to ultraviolet C irradiation.

- Affymetrix Human Exon 1.0 ST Array [transcript (gene) version (huex10st)
Description
To understand the roles of molecules in functional differentiation among adult human tissues, we performed a systematic survey of mRNA, protein, and protein phosphorylation as well as miRNA expression, in three tissues: cerebellum, prefrontal cortex and liver. We found that tissues were clearly distinct from one another at all levels. Furthermore, our results showed that miRNA differently expressed between tissues have significant, but modest effect on expression of mRNA and somewhat stronger effect on expression of proteins among the tissues.

Description
Reprogramming process can bring in genetic and epigenetic abnormalities, and these abnormalities can endow effect on gene expression of obtained iPSCs. We used Microarray to detect obvious gene expression differences between iPS cells ,which were induced using one episomal plasmid from C57BL/6 mouse embryonic fibroblasts, and one normal ES cell line from C57BL/6 inbred strain mice.
