Expression data from HEK wild-type cells treated with geneticin (16uM) or left untreated

ABSTRACT: In order to study the cellular response to aminoglycoside-induced mistranslation, we used a whole-genome microarray analysis of geneticin-treated versus untreated cells, which revealed a broad transcriptional response totaling 705 genes. comparison of four geneticin treated biological replicates with four untreated biological replicates (selected for a fold change > 1.2, Benjamini-Hochberg corrected p-value < 0.05)

Identification of genes controlled by Ikaros and IL-7 in the mouse Ikaros-deficient pre-B cell line BH1

Project description:The aim of the experiment was to compare to single and combined effect of Ikaros activation and IL-7 withdrawal in the Ikaros-null pre-B cell line BH1 The mouse BH1 pre-B cell line was transduced with retroviruses encoding Bcl2 and an Ikaros-estrogen receptor fusion protein. Doubly transduced cells were purified by FACS (BH1-Bcl2-Ik1ER). The transcriptome of these cells was analyzed at time 0, and after 6h and 24h of induction of Ikaros activity with 4-hydroxytamoxifen (4OHT) and/or withdrawal of IL-7. Samples from 2 independent experiments were analyzed (exp1 and exp2).

MOF-associated complexes have overlapping and unique roles in regulating pluripotency in embryonic stem cells and during differentiation [array]

Project description:The histone acetyltransferase (HAT) Mof is essential for mouse embryonic stem cells (mESC) pluripotency and early development. Mof is the enzymatic subunit of two different HAT complexes, MSL (Male-Specific Lethal) and NSL (Non-specific lethal). The individual contribution of MSL and NSL complexes to transcription regulation in mESCs is not well understood. Our genome-wide analysis of MSL and NSL localization show that i) MSL and NSL bind to specific and common sets of expressed genes, ii) NSL binds at promoters, iii) while MSL binds in gene bodies. Knockdown of Msl1 leads to a global loss of histone H4K16ac indicating that MSL is the main HAT acetylating H4K16 in mESCs. MSL was enriched at many mESC-specific genes, but also at bivalent domains. Thus, NSL and MSL HAT complexes differentially regulate specific sets of expressed genes in mESCs. Furthermore, MSL is essential for the regulation of key mESC-specific and bivalent developmental genes. Gene expression was analysed through microarrays in mESCs infected with shRNA vectors expressing either a non-target control, shRNA against Nsl1 or Msl1 to knockdown Nsl1 or Msl1.

The Fragile X Mental Retardation Protein (FMRP) controls diacylglycerol kinase in neurons

Project description:In this study, we sought to identify the mRNAs associated to FMRP protein in mouse cortical neuron using a cross linking immunoprecipitation and microarray (CLIP-microarray). The mRNAs crosslinked at 254 nm to FMRP in mouse cortical neurons cultured 8 days in vitro (8 DIV) were immunoprecipitated with H120 anti-FMRP (Santa Cruz) and reverse transcribed to labeled cDNAs with Ovation Pico WTA system V2 (Nugen) and hybridized on Mouse Gene 1.0ST (Affymetrix) We analyzed total RNA (Input) and FMRP-CLIPed RNA (Clip) from 10 primary cortical neuron mouse cultures (5 Wt Input, 5 FMR1-KO Input, 5 Wt Clip, 5 FMR1-KO Clip). Array data was processed by Affymetrix Exon Array Computational Tool. No technical replicates were performed.

Regulatory interplay of Cockayne syndrome B ATPase and stress-response gene ATF3 following genotoxic stress

Project description:Gene expression profile in CS1AN deficient and CSBwt restored cell lines after 24 hours of UV or alphe-amanitin treatment (only for restored). The comaprison of expression profile between 0 and 24 hours revealed continouse suppresion of transcription upon UV treatment in CS1AN cell line and alpha-amanitin treated CS1AN CSBwt restored cells. Gene expression profiles were obtained in duplicates for un-treated (assigned as 0h time point) and treated (assigned as 24h time point) cells.

Ikaros-induced gene expression chages upon Ikaros re-expression in the ILC87 Ikaros-deficient tumor cell line

Project description:We used microarrays to analyze gene expression changes in the Ikaros null ILC87 T cell tumor line after re-expression of Ikaros. ILC87 cells were transduced to stably express the 4-hydroxytamoxifen-inducible (4OHT) Ikaros1-ER fusion protein. ILC87-Ik1-ER cells were treated with mock (EtOH) or 4OHT for 1 day and the global gene expression changes were assessed by microarray analysis.

Molar and incisor development

Project description:One of the key questions in developmental biology is how from universally shared molecular mechanisms and pathways, is it possible to generate organs displaying similar or complementary functions, with a wide range of different shapes or tissue organization? The dentition represents a valuable system to address the issues of differential molecular signatures generating specific tooth types. We performed a comparative transcriptomic analysis of developing murine lower incisors, mandibular molars and maxillary molars at the developmental cap stage (E14.5) prior to recognizable tooth shape and cusp pattern. We compared gene expression profiles in developing murine lower incisor and molars, as well as between the lower and upper (mandibular and maxillary) first molars
