Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Growth arrest and DNA damage induced protein (GADD34) is a regulator of protein phosphatase 1 and promotes eIF2 dephosphorylation under conditions of various stress. eIF2 phosphorylation at Ser 51 is a key nodule controlling the general rate of protein synthesis and activation of integrated stress response pathways. In GADD34 knockout conditions, dysregulated eIF2 phosphorylation is likely to produce abnormalities in the integrated stres response. GADD34 can be induced by many different stresses but oxidative stress by arsenite produced highest GADD34 levels in various cell lines tested. We aim to evaluate early gene expression changes on arsenite treatment and examine if GADD34 influences the profile of genes induced by oxidative stress.
Publication Title

Description
A simultaneous engagement of different pathogen recognition receptors provides a tailor made adaptive immunity for an efficient defence against distinct pathogens. For example, cross talk of TLR and c-type lectin signalling effectively shapes distinct gene expression patterns by integrating the signals at the level of NF-B. Here, we extend this principle to a strong synergism between the Dectin-1 agonist, curdlan, and an inflammatory growth factor, GM-CSF. Both together act in synergy in inducing a strong inflammatory signature which converts immature DCs to potent effector DCs. A variety of cytokines (IL-1, IL-6, TNF-, IL-2 and IL-12p70), costimulatory molecules (CD80, CD86, CD40 and CD70), chemokines (CxCl1, CxCl2, CxCl3, CCl12, CCl17) as well as receptors and molecules involved in fugal recognition and immunity such as Mincle, Dectin-1, Dectin-2 and Pentraxin 3 are strongly up-regulated in DC treated simultaneously with curdlan and GM-CSF. The synergistic effect of both stimuli resulted in strong IKB phosphorylation, in its rapid degradation and in enhanced nuclear translocation of all NF-B subunits. We further identified MAPK ERK, as one possible integration site of both signals, since its phosphorylation was clearly augmented when curdlan was co-applied with GM-CSF. Our data demonstrate that the immunomodulatory activity of curdlan requires an additional signal provided by GM-CSF to successfully initiate a robust -glucan specific cytokine and chemokine response. The integration of both signals clearly prime and tailor a more effective innate and adaptive response against invading microbes and fungi.

Description
Nasopharyngeal carcinoma (NPC) is a prevalent malignancyt disease in Southeast Asia among the Chinese population. Aberrant regulation of transcripts has been implicated in many types of cancers including NPC. Herein, we characterized mRNA and miRNA transcriptomes by RNA sequencing (RNASeq) of NPC model systems. Overall design: Matched total mRNA and small RNA of undifferentiated Epstein-Barr virus (EBV)-positive NPC xenograft X666 and its derived cell line C666, well-differentiated NPC cell line HK1, and the immortalized nasopharyngeal epithelial cell line NP460 have been sequenced by Solexa technology.
Publication Title
Integrated mRNA and microRNA transcriptome sequencing characterizes sequence variants and mRNA-microRNA regulatory network in nasopharyngeal carcinoma model systems.

Description
This study aimed to explore the role of NIPP1 in adult germline cell proliferation and differentiation, using a ubiquitous inducible NIPP1 knockout (TKO) mouse model. To gain unbiased insight into the molecular mechanism that underly the sertoli-only phenotype in TKO, we performed a comparative RNA sequencing profiling of control and TKO, in which NIPP1 was tamoxifin-induced depleted. Overall design: Two genotypes are compared after treatment with tamoxifen. The control genotype (UBC CRE-ERT2+/- Ppp1r8 fl/+) looses the floxed allele of PPP1R8 (aka NIPP1) as a consequence of the treatment with tamoxifen and becomes heterozygous for PPP1R8. The KO genotype (UBC CRE-ERT2+/- Ppp1r8 fl/-) also looses the floxed allele of PPP1R8 as a consequence of the tamoxifen treatment and becomes homozygous KO. For each genotype, 4 replicates are profiled.
