TranscriptomicsSub-chronic forestomach transcriptional response in adult male MutaTMMouse following oral exposure to benzo(a)pyrene
Benzo(a)pyrene is a well-established human carcinogen in humans and rodents. In the present study, we sought to determine the dose- and time-dependent changes in gene expression upon oral exposure to benzo(a)pyrene. Adult male MutaTMMouse were exposed to three doses of benzo(a)pyrene or vehicle cont...

TranscriptomicsTranscription profiling of Streptococcus pneumoniae TCS08 mutant (disrupted in rr08) compared to the parent wild type strain TIGR4
Transcriptional changes of an TCS08 mutant (disrupted in rr08) compared to the parent wild-type strain TIGR4 when both strains were cultured to early logarithmic growth phase in THY broth.

GenomicsAmplification of siRNA in Caenorhabditis elegans generates a transgenerational sequence-targeted histone H3 lysine 9 methylation footprint
Exogenous double-stranded RNA (dsRNA) has been shown to exert homology-dependent effects at the level of both target mRNA stability and chromatin structure. Using C. elegans undergoing RNAi as an animal model, we have investigated the generality, scope, and longevity of chromatin-targeted dsRNA effe...

TranscriptomicsCryptic Transcription in a set2∆ in Saccharomyces cerevisiae
In cells lacking the histone methyltransferase Set2, initiation of RNA polymerase II transcription occurs inappropriately within the protein-coding regions of genes, rather than being restricted to the proximal promoter. Here, we mapped the transcripts produced in an S. cerevisiae strain lacking Set...

TranscriptomicsMyelodysplastic syndrome: NUP98-HoxD13 (NHD13) expression effect on hematopoietic stem cells
Analysis of Lin-c-Kit+Sca-1- haematopoietic stem cells (HSCs) expressing the Nup98-HoxD13 (NHD13) fusion gene. NHD13 induces myelodysplastic syndrome (MDS) in mice. Results provide insight into the molecular basis of the myelodysplastic phenotype WT mouse HSCs were compared to an NHD13 mutant sequen...

TranscriptomicsNrf2b: a novel zebrafish paralog of the oxidant-responsive transcription factor Nrf2.
We identified a novel paralog of the antioxidant response element transcription factor, Nrf2 in zebrafish. To determine whether the paralogs Nrf2a and Nrf2b regulate different sets of genes, we performed loss-of-function experiments followed by microarray-based gene expression profiling, performed ...

TranscriptomicsTrans. Profiling of Immortalized Melanocyte Cell Lines Identifies GPNMB as a Melanoblast-Expressed, MITF-Dependent Gene
Gene expression profiling of tissues derived from different genetic backgrounds can provide insight to potential phenotype-related changes in gene expression. We have compared wildtype C57BL/6 (melan-Ink4a) melanocyte cell gene expression to that of, “brown“ Tyrp1b/ b (melan-Ink4a-b) and “cho...

TranscriptomicsTranscription profiling validation of an custom mouse oligo array using liver samples following treatment with the hepatotoxin phenobarbital and variable hybridization protocols
The use of custom-made focused microarrays has become a popular alternative, allowing the study of genes relevant to a specific hypothesis. To address the limitations of commercial arrays in toxicogenomics investigations, we have developed a custom mouse oligonucleotide microarray, the HC ToxArrayTM...

TranscriptomicsRNA Pol III transcriptomes and relationships to Pol II promoters, enhancer-binding factors and chromatin domains
RNA polymerase III transcribes many noncoding RNAs (e.g. tRNAs) important for translational capacity and other functions. Here, we localized RNA polymerase III, alternative TFIIIB complexes (BRF1/2) and TFIIIC in HeLa cells, determining the Pol III transcriptome, defining gene classes, and reveali...

TranscriptomicsRNA-seq of hepatocytes obtained through step-wise differentiation of hIPSCs from a patient with A1AT deficiency and its point mutation-corrected isogenic hIPSC line. Comparison to primary hepatocytes from a healthy donor and an A1AT-deficient patient.
A1AT deficiency is an autosomal not recessive disorder caused by mutations in the SERPINA1 gene. Individuals with the Z variant retain polymerised protein in the endoplasmic reticulum of hepatocytes, predisposing them to liver disease. This study primarily aimed to uncover the molecular mechanisms t...
