Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Human peripheral blood mononuclear cells were cultured in presence of H37Ra strain at 37oC, 5%CO2. Cellular aggregates were collected at 24h, and RNA extracted and hybridized to Affymetrix microarrays (HG-U133). Raw data from microarray experiments was analyzed with dCHIP and SAM programs to determine the significance of changes at the biological context.

- Affymetrix Human Transcriptome Array 2.0 (hta20)
Description
How chromatin controls transcription elongation and splicing is an open question. Here we determine the transcriptomic changes of cells partially depleted of core histones. For that we construct a cell line with Doxycycline-controlled levels of the histone regulatory protein SLBP (HCT-shSLBP). HCT-shSLBP is derived from the human colon cancer cell line HCT116.
Publication Title
Defective histone supply causes changes in RNA polymerase II elongation rate and cotranscriptional pre-mRNA splicing.

- Affymetrix Human Transcriptome Array 2.0 (hta20)
Description
We identified RNA targets of Matrin3 using SH-SY5Y by PAR-CLIP analysis. Because Matrin3 mainly bound to intron of pre-mRNA, in order to find the effect of Matrin3 on splicing pattern and expression, we knocked down Matrin3 using SH-SY5Y cells by electroporation and extracted total RNAs from those cells. The total RNAs were subjected to whole transcripts microarray GeneChip Affymetrix Human Transcriptome array 2.0.
Publication Title
Matrin3 binds directly to intronic pyrimidine-rich sequences and controls alternative splicing.

Description
Controlled hypobaria presents biology with an environment that is never encountered in terrestrial ecology, yet the apparent components of hypobaria are stresses typical of terrestrial ecosystems. High altitude, for example, presents terrestrial hypobaria always with hypoxia as a component stress, since the relative partial pressure of O2 is constant in the atmosphere. Laboratory-controlled hypobaria, however, allows the dissection of pressure effects away from the effects typically associated with altitude, in particular hypoxia, as the partial pressure of O2 can be varied. In this study, whole transcriptomes of plants grown in ambient (97 kPa/pO2 = 21 kPa) atmospheric conditions were compared to those of plants transferred to five different atmospheres of varying pressure and oxygen composition for 24 h: 50 kPa/pO2 = 10 kPa, 25 kPa/pO2 = 5 kPa, 50 kPa/pO2 = 21 kPa, 25 kPa/pO2 = 21 kPa, or 97 kPa/pO2 = 5 kPa. The plants exposed to these environments were 10 day old Arabidopsis seedlings grown vertically on hydrated nutrient plates. In addition, 5 day old plants were also exposed for 24 h to the 50 kPa and ambient environments to evaluate age-dependent responses. The gene expression profiles from roots and shoots showed that the hypobaric response contained more complex gene regulation than simple hypoxia, and that adding back oxygen to normoxic conditions did not completely alleviate gene expression changes in hypobaric responses.

- Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
CHD8 is an ATPase of the SNF2 family involved in ATP-dependent nucleosome remodeling. Our data indicate that in the presence of progestin (R5020), a progesterone receptor (PR) agonist, CHD8 is recruited to a number of PR enhancers. To correlate CHD8 binding sites with CHD8-regulated gene expression we performed a transcriptomic analysis of T47D-MTVL cells transfected with a control siRNA or a siRNA specifically targeting CHD8 and stimulated during 6h with progestin or vehicle. CHD8-dependent genes presented lower induction of up-regulated genes and lower repression of down-regulated genes, indicating that CHD8 is required for progesterone-dependent regulation of a subset of genes.
Publication Title
The chromatin Remodeler CHD8 is required for activation of progesterone receptor-dependent enhancers.
