Description
Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disorder in industrialized countries. Liver samples from morbidly obese patients (N=45) with all stages of NAFLD and controls (N=18) were analysed by array-based DNA methylation and mRNA expression profiling. NAFLD-specific expression and methylation differences were seen for nine genes coding for key enzymes in intermediate metabolism (including PC, ACLY, PLCG1) and insulin/insulin-like signalling (including IGF1, IGFBP2, PRKCE) and replicated by bisulfite pyrosequening (independent N=39). Transcription factor binding sites at NAFLD-specific CpG sites were >1000-fold enriched for ZNF274, PGC1A and SREBP2. Intra-individual comparison of liver biopsies before and after bariatric surgery showed NAFLD-associated methylation changes to be partially reversible. Post-bariatric and NAFLD-specific methylation signatures were clearly distinct both in gene-ontology and transcription factor binding site analyses, with >400-fold enrichment of NRF1, HSF1 and ESRRA sites. Our findings provide one of the first examples of treatment-induced epigenetic organ remodelling in humans.

Description
Nijmegen Breakage Syndrome (NBS) is a rare autosomal recessive genetic disorder, first described 1981 in Nijmegen, Holland. The characteristics of NBS include genomic instability (resulting in early onset of malignancies), premature aging, microcephaly and other growth retardations, immune deficiency, and impaired puberty and fertility in females. The consequence of these manifestations is a severe decrease in average life span, caused by cancer or infection of the respiratory and urinary tract. We reprogrammed fibroblasts from NBS patients into induced pluripotent stem cells (iPSCS) to bypass premature senescence and to generate an unlimited cell source for modeling purposes. We screened the influence of antioxidants on intracellular levels of ROS and DNA damage and found that EDHB was able to decrease DNA damage in the presence of high oxidative stress. Furthermore, we found that NBS fibroblasts, but not NBS-iPSCs were more susceptible to the induction of DNA damage than their normal counterparts. We performed global transcriptome analysis comparing NBS to normal fibroblasts and NBS-iPSCs to hESCs. There, we found, that TP53 was activated and cell cycle genes broadly down-regulated in NBS fibroblasts and up-regulation of glycolysis specifically in NBS-iPSCs.

Description
The hepatitis E virus (HEV), a non enveloped RNA virus, causes viral hepatitis. The viral open reading frame 2 (ORF2) protein represents the capsid protein of HEV which is known to cause endoplasmic reticulum stress in ORF2 expressing cells. The initiation of endoplasmic reticulum stress induced apoptosis mainly involves the transcriptional activation of pro-apoptotic gene CHOP which will further trigger the major apoptotic pathways. However, the activation of CHOP by ORF2 protein in this study does not induce apoptotic markers such as Bax translocation to mitochondria. We have used the Affymetrix microarray platform to screen the pro-apoptotic effects induced by the expression of ORF2 protein in human hepatic cell lines (Huh7). The Huh7 cells were transduced either with recombinant adenovirus encoding the HEV ORF2 (Ad-ORF2) or an adenovirus encoding the green fluorescent protein (Ad-GFP). The array results consistently showed an ORF2 specific induction of mRNA corresponding to the chaperones Hsp72, Hsp70B and co-chaperone Hsp40. These studies provide further mechanisms of the ER stress mediated pro apoptotic effects caused by the ORF2 protein and its potential role for the activation of anti-apoptotic activity of the host cell.
