Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Glial progenitor cells (GPCs) of the adult human white matter, which express gangliosides recognized by monoclonal antibody A2B5, are a potential source of glial tumors of the brain. We used A2B5-based sorting to extract progenitor-like cells from a range of human glial tumors, that included low-grade glioma, oligodendroglioma, oligo-astrocytomas, anaplastic astrocytoma, and glioblastoma multiforme. The A2B5+ tumor cells proved tumorigenic upon orthotopic xenograft, and the tumors generated reflected the phenotypes of those from which they derived.
Publication Title

Description
Digital gene expression profiling was used to invesigate the differetiated genes between primary mouse hepatic stellate cells infected with AGGF1 adenovirus particles or negative control adenovirus pairticles. Overall design: Primary hepatic stellate cells isolated from mice were cultured in vitro, infected with AGGF1 adenovirus particles or negative control adenovirus particles, at day 8, total RNA were prepared and used for digital gene expression tag profiling.

Description
Ribosome profiling of MDA-MB-231 cells treated with Silvestrol to monitor transcriptome wide, eIF4A-dependent changes in translation efficiency Overall design: Translation efficiency (TE) of mRNAs dervied from ribosome footprints was monitored in the presence or absence of 25 nM Silvestrol, an inhibitor of eukaryotic translation initiation factor 4A (eIF4A). Transcripts with reduced TE in the presence of Silvestrol were compare to transcripts with reduced TE in the presence of INK128, a catalytic mTOR inhbitor.
Publication Title
Transcriptome-wide characterization of the eIF4A signature highlights plasticity in translation regulation.

Description
The growth and fruit quality of grapevine are widely affected by abnormal climatic conditions such as water deficit. But how grapevine responds to drought stress is still largely unknown. Here we found that VaNAC26, a member of NAC transcription factor family, was up-regulated dramatically during cold, drought and salinity treatments in Vitis amurensis, a cold and drought-hardiness wild Vitis species. Ectopic overexpression of VaNAC26 enhanced the drought and salt tolerances in transgenic Arabidopsis. Higher activities of antioxidant enzymes and the lower concentration of H2O2 and O2- were found in VaNAC26-OE lines than in wild type plants under drought stress. These results indicate that the reactive oxygen species (ROS) scavenging was enhanced by VaNAC26 in transgenic lines. Microarray based transcriptome analysis reveals that genes related to jasmonic acid (JA) synthesis and signaling were up-regulated in VaNAC26-OE lines under both normal and drought conditions. VaNAC26 showed a specific binding ability on NACRS motif, which was broadly existent in the promoter regions of up-regulated genes in transgenic lines. Endogenous JA content was found increased obviously in VaNAC26-OE-2/3 lines. Our data suggests that VaNAC26 responds to abiotic stresses and may enhance the drought tolerance by transcriptional regulation of JA synthesis in Arabidopsis.

Description
Abraxane, a nanoparticle (NP) formulation of paclitaxel (PTX), has been demonstrated to be more effective than Taxol, the small molecule formulation, for the treatment of breast cancer and non-small cell lung cancer (NSCLC). It was reported that Abraxane existed in plasma as particles with the size of ~10 nm. NPs get in and out of the cells by endocytosis and exocytosis, whereas small molecules by diffusion and efflux. It is intriguing to know whether the improved pharmaceutical performance is related to the “too-big-to-be-pumped-out” phenomenon. Here we established an Abraxane-resistant NSCLC cell line A549/Abr and compared its transcriptomes with that of the Abraxane-sensitive parental cell line by RNA-Seq technology. To our surprise, the most significantly up-regulated genes were ABC transporters, the common efflux pump for small molecules. We further found that the ABCB1 inhibitor Verapamil reversed the drug resistance and confirmed the important role of ABCB1 in Abraxane resistance. Overall design: mRNA profiles of A549 and A549/Abr cells were generated using Illumina Hiseq 2000 and compared.

Oculo-facio-cardio-dental syndrome (OFCD) is a rare genetic disorder characterized by teeth with extremely long roots (radiculomegaly), and craniofacial, eye and cardiac abnormalities. The mutation of the transcriptional co-repressor BCOR has been identified as being responsible for oculo-facio-cardio-dental (OFCD) syndrome.

Description
Cryptococcal osteomyelitis is an infrequent infection which is usually associated with disseminated cryptococcosis or underlying immunocompromised conditions. Here we described a rare case with isolated iliac cryptococcosis in an immunocompetent patient. Through histological, microbial, and molecular biological examinations, the pathogen was finally identified as C. neoformans VNI genotype, which likely originated from environmental bird droppings. The clinical isolate was hypomelanized but fully virulent in mouse infection model. The patient displayed lower CD4+-T lymphocyte ratio, reduced serum IFN-? and IL-12, and dysregulated transcriptional profile of blood leukocytes compare with healthy host. After surgical excision and 34 weeks' antifungal treatment, the patient got clinical cured. Our study suggested that cryptococcosis development was closely associated with the interaction of fungal agent and host immunity. Accurate diagnosis of bone cryptococcosis depends mainly on histological and fungal examinations. A combination of antifungal agent treatment regimen and surgery were quite effective for resolving bone cryptococcosis. Overall design: mRNA profiles of an Immunocompetent Patient and normal control''s blood were generated by deep sequencing, using Illumina HiSeq 2500
