Description
Roberts syndrome (RBS) is a human developmental disorder caused by mutations in the cohesin acetyltransferase ESCO2. We previously reported that mTORC1 was inhibited and overall translation was reduced in RBS cells. Treatment of RBS cells with L-leucine partially rescued mTOR function and protein synthesis, correlating with increased cell division. In this study, we use RBS as a model for mTOR inhibition and analyze transcription and translation with ribosome profiling to determine genome-wide effects of L-leucine. The translational efficiency of many genes is increased with Lleucine in RBS cells including genes involved in ribosome biogenesis, translation, and mitochondrial function. snoRNAs are strongly upregulated in RBS cells, but decreased with L-leucine. Imprinted genes, including H19 and GTL2, are differentially expressed in RBS cells consistent with contribution to mTORC1 control. This study reveals dramatic effects of L-leucine stimulation of mTORC1 and supports that ESCO2 function is required for normal gene expression and translation. Overall design: 42 samples of human fibroblast cell lines with various genotypes (wt, corrected, and esco2 mutants) are treated with l-leucine or d-leucine (control) for 3 or 24 hours. Biological replicates are present.

Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
To gain a more depth knowledge of repressive epigenetic gene regulation in UCC, we have profiled H3K9m3 and H3K27m3 in normal and malignant urothelial cells. We matched these profiles to those 5-methylcytosine and gene expression. We hypothesized that differences represent pro-carcinogenic events within the urothelium.

Description
Aging signatures developed from a longitudinal study design are dominated by reduced transcription of genes involved in protein synthesis Aging is a multifactorial process where the impact of singular components still remains unclear. Furthermore, previous studies were focused on measuring specific traits such as DNA -methylation and used categorical group-wise designs, unable to capture intra-individual signature changes. Here we have developed a new method for a longitudinal, age-related analysis combining the merits of a pair-wise design with the statistical power of gene set enrichment analysis. We present an integrated analysis, including transcriptional changes and genome-wide epigenetic changes in DNA- methylation, H3K4- and H3K27- histone methylation in promoter regions. We tested our method on a rare collection of paired skin fibroblast samples from male middle age to old age transitions and obtained functional, age-related clusters. By using a set of only ten individuals, we could demonstrate a high overlap of functional terms to previously established tissue-independent age signatures including extracellular matrix, apoptosis and oxidative stress. Importantly, we identify protein translation-related processes as the main cluster of age-driven, specific down regulation. Overall design: Evaluation of transcriptional changes in matched sample pairs of primary skin fibroblasts from middle and old age.
