View SamplesThese data show that Paupar, a CNS expressed long non-coding RNA (lncRNA), directly and functionally associates with KAP1, an essential epigenetic regulatory protein. Transcriptome profiling of N2A cells identified 1,913 differentially expressed genes whose expression significantly changed (at a 5% false discovery rate [FDR]) greater than 1.4-fold (log2 fold change 0.5) upon KAP1 depletion. Examination of the intersection of KAP1 and Paupar transcriptional targets showed that Paupar and KAP1 control expression of a shared set of target genes that are enriched for regulators of neuronal function and cell cycle in N2A cells. Furthermore, CHART-seq and ChIP-seq derived Paupar-KAP1 genome-wide co-occupancy maps revealed a 4-fold enrichment of overlap between Paupar and KAP1 bound sequences on chromatin. This study also indicates that Paupar promotes KAP1 chromatin occupancy and H3K9me3 deposition at a subset of distal targets, through formation of a ribonucleoprotein complex containing Paupar, KAP1 and the PAX6 transcription factor. These observations provide important conceptual insights into the trans-acting modes of lncRNA-mediated epigenetic regulation and the mechanisms of KAP1 genomic recruitment.

View SamplesGrowth 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.
Oxidative stress promotes SIRT1 recruitment to the GADD34/PP1α complex to activate its deacetylase function.

View SamplesNasopharyngeal 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.

View SamplesLysozyme-GFP ER-HoxA9 cells were cultured in the presence of estradiol (active ER-HoxA9) or in the absence of estradiol (inactive ER-HoxA9). Samples were taken at 10 time points over a 120 hour time course of myeloid differentiation to examine those gene expression changes that accompany differentiation upon the release of HoxA9 differentiation arrest.

View SamplesA 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.
Synergism between curdlan and GM-CSF confers a strong inflammatory signature to dendritic cells.
