Description
Polyglutamine(polyQ) expansion of 1A voltage-dependent calcium channel (Cav2.1) is the causative mutation of spinocerebellar ataxia type 6 (SCA6). The C-terminal fragment (CTF) of Cav2.1 makes aggregates in the cytoplasm of SCA6 Purkinje cells and may relate to the pathogenesis. In order to identify genes associated with polyQ expansion and subcellular localization of CTF, we analyzed gene expression profiles of PC12 rat pheochromocytoma cells using Tet-off system.
Publication Title
Cytoplasmic location of α1A voltage-gated calcium channel C-terminal fragment (Cav2.1-CTF) aggregate is sufficient to cause cell death.

Description
Background: SH-SY5Y cells exhibit a neuronal phenotype when treated with all-trans retinoic acid (RA), but the molecular mechanism of activation in the signaling pathway mediated by phosphatidylinositol 3-kinase (PI3K) is not sufficiently understood. To shed new light on the mechanism, we comprehensively compared the gene expression profiles between SK-N-SH cells and two subtypes of SH-SY5Y cells (SH-SY5Y-A and SH-SY5Y-E), each of which showed a different phenotype during RA-mediated differentiation. Results: SH-SY5Y-A cells differentiated in the presence of RA, whereas RA-treated SH-SY5Y-E cells required additional treatment with brain-derived neurotrophic factor (BDNF) for full differentiation. In combination with perturbation using a PI3K inhibitor, LY294002, we identified 386 genes and categorized them into two clusters dependent on the PI3K signaling pathway during RA-mediated differentiation in SH-SY5Y-A cells. Transcriptional regulation of the gene cluster was greatly reduced in SK-N-SH cells or partially impaired in SH-SY5Y-E cells in coincidence with a defect in the neuronal phenotype of these cell lines. Additional stimulation with BDNF induced a set of neural genes which were down-regulated in RA-treated SH-SY5Y-E cells but were abundant in the differentiated SH-SY5Y-A cells. Conclusions: We identified the gene clusters controlled by PI3K- and TRKB-mediated signaling pathways during differentiation in two subtypes of SH-SY5Y cells. TRKB-mediated bypass pathway compensates for the impaired neural functions generated by defects in several signaling pathways including PI3K in SH-SY5Y-E cells. The expression profiling data are useful for further studies to elucidate the signal transduction-transcriptional network including PI3K and/or TRKB.

Illumina HiSeq 2500
Description
By conditionally deleting BRD4 at various stages of thymic differentiation, we have established that BRD4 deficiency selectively affects a unique developmental subpopulation of thymocytes. Overall design: We examined by RNA-seq the effect on gene expression of BRD4 deletion in ex vivo DN, ISP, DP, CD4 and CD8 thymocyte subpopulations. The analysis was also performed on WT or BRD4 deleted ISP and DP thymocytes cultured for 16 hours at 37oC In this analysis, the conditional deletion of BRD4 (cKO) is achieved using the LCK-cre Transgene.

Description
We found constitutive upregulation and higher degree induction of drug metabolism and disposition-related genes in a three-dimensional HepG2 culture. The upregulated genes are those believed to be regulated by different regulatory factors. The global gene expression analysis by Affymetrix GeneChip indicated that altered expressions of microtubule-related genes may change expressed levels of drug metabolism and disposition genes. Stabilization of the microtubule molecules with docetaxel, a tubulin stabilizing agent, in the two-dimensional culture showed gene expression patterns similar to those in the three-dimensional culture, indicating that culture environment affects drug metabolism functions in HepG2 cells.
