The bacterial transcription factor RpoN regulates an extensive network of genes whose products are involved in diverse biological functions. We constructed a small peptide termed the RpoN molecular roadblock, which binds to and blocks transcription from RpoN promoters. This RpoN molecular roadblock can be used in any bacterium to obtain information on the RpoN regulon.

View SamplesWe developed conditional knockout mice where the transcription factor Elf5 (also called ESE-2) is deleted in the mammary glands. Loss of Elf5 results in block in alveologenesis and epithelial differentiation defects. Mammary gland samples from Elf5 knockout and wild type animals were analyzed for global transcriptome changes.
Elf5 inhibits the epithelial-mesenchymal transition in mammary gland development and breast cancer metastasis by transcriptionally repressing Snail2.

View SamplesWe developed a Tet-inducible system to express deltaNp63alpha isoform under the control of keratin 5 promoter. Transgenic mice, which were Bigenic (BG) developed a severe skin phenotype with abnormal keratinocyte differentiation and defects in hair follicle development and cycling. Skin samples from transgenic animals and wild type animals were analyzed for global transcriptome changes.

Expression from these cell types will compared to three whole genome open chromatin methodologies: DNaseI hypersensitivity (DNase-seq), Formaldehyde-Assisted Isolation of Regulatory elements (FAIRE-seq), and Chromatin Immunoprecipitation (ChIP-seq) .

View SamplesIn this study, we tested if miRNAs are altered in amygdala and ventral striatum as a consequence of prenatal ethanol exposure and/or social enrichment. miRNA samples from 72 male and female adolescent rats were analyzed by RNA-Seq analysis and Affymetrix miRNA arrays. Several miRNAs showed significant changes due to prenatal ethanol exposure or social enrichment in one or both brain regions. Some of the miRNA changes caused by ethanol were reversed by social enrichment. The top predicted gene targets of these miRNAs were mapped and subjected to pathway enrichment analysis. We also directly examined the evidence for modulation of target mRNAs in whole transcriptome microarray data from the same rats. Among the pathways most strongly affected were p53, CREB, Glutamate and GABA signaling. Together, our data suggest a number of novel epigenetic mechanisms for social enrichment to reverse the effects of ethanol exposure.
