View SamplesING1b and GADD45a are nuclear proteins involved in the regulation of cell growth, apoptosis and DNA repair. We found that ING1b and GADD45a physically and functionally interact in the epigenetic regulation of specific target genes. In order to characterise the functional ING1b-GADD45a interaction, we performed a gain-of-function experiment in HEK293T cells by individual and combinatorial plasmid transfections and then analysed the transcriptional response via expression microarray profiling.

We found that ING1b and GADD45a physically and functionally interact in the epigenetic regulation of specific target genes. In order to study this interaction further, we analysed the transcriptional changes in MEF cells from single and double Ing1/Gadd45 knockout mice via microarray profiling.

View SamplesChlorpyrifos is an organophosphorus insecticide that despite imposed restricitions on its use by the EPA, is one of the most commonly used insecticides. Although CPF is so widely used little is known about its effect on overall gene expression in vivo.
Subtoxic chlorpyrifos treatment resulted in differential expression of genes implicated in neurological functions and development.

View SamplesThe study was performed using primary rat hepatocyte in culture from 4 adult male Sprague-Dawley rats to investigate the changes in gene expression under low dose (4M) and short exposure (3hrs) of cadmium chloride. By comparing the gene expression profiles of control and cadmium-treated cells, the most dramatic and significant changes were for those genes associated with transcriptional regulation, antioxidant response and control of protein integrity. Changes in other genes involved in cellular physiological responses such as inflammation, growth and apoptosis were also observed. Results were further confirmed by quantitative real time polymerase chain reaction (qRT-PCR).

View SamplesWe report that Dnmt1 is crucial during perinatal intestinal development. Loss of Dnmt1 in intervillus progenitor cells causes global hypomethylation, DNA damage, premature differentiation, and apoptosis, and consequently, loss of nascent villi. We further confirm the critical role for Dnmt1 during crypt development using the in vitro organoid culture system, and illustrate a clear differential requirement for Dnmt1 in immature versus mature organoids. These results demonstrate an essential role for Dnmt1 in maintaining genomic stability during intestinal development and the establishment of intestinal crypts. Overall design: We performed RNA-Seq of control and Dnmt1-ablated intestinal progenitor cells isolated from parrafin embedded tissues by laser capture microdissection (LCM).
Dnmt1 is essential to maintain progenitors in the perinatal intestinal epithelium.

View SamplesThe pre-synaptic protein -synuclein is a key player in the pathogenesis of Parkinson's disease. Together with accumulation and missfolding of -synuclein protofibrils serve as seed structures for the aggregation of numerous proteins in the cytoplasm of neuronal cells, the so-called Lewy bodies. Furthermore, missense mutations in the SNCA gene and gene multiplications lead to autosomal dominant forms of familiar PD. However, so far the exact biological role of -synuclein in normal brain is elusive. To gain more insights into the biological function of this protein we monitored whole genome expression changes in dopaminergic neuroblastoma cells (SH-SY5Y) caused by a 90% reduction of -synuclein by RNA interference.
