<h4>Motivation</h4>A rapid progression of esophageal squamous cell carcinoma (ESCC) causes a high mortality rate because of the propensity for metastasis driven by genetic and epigenetic alterations. The identification of prognostic biomarkers would help prevent or control metastatic progression. Expression analyses have been used to find such markers, but do not always validate in separate cohorts. Epigenetic marks, such as DNA methylation, are a potential source of more reliable and stable bio ...[more]

Epigenome analysis of normal and preeclamptic placenta samples

Project description:Preeclampsia (PE), a hypertensive disorder of pregnancy, is hypothesized to be associated with, if not mechanistically related to abnormal placental function. However, the exact mechanisms regulating the pathogenesis of PE remain unclear. While many studies have investigated changes in gene expression in the PE placenta, the role of epigenetics in PE associated placental dysfunction remains unclear. Using the genome-wide Illumina Infinium Methylation 450 BeadChip array, we analyzed gene-specific alterations in DNA methylation in placental biopsies collected from normal pregnant women delivering at term (n=14), with term PE (≥37 weeks; n=19) or with preterm PE (<37 weeks, n=12). Of the 485,582 gene loci on the array, compared to controls, 229 loci were differentially methylated in PE placentas and 3411 loci were differentially methylated in preterm PE (step up p-value <0.05 and >5% methylation difference). Functional annotation of the differentially methylated genes in preterm PE placentas revealed a 32 gene cluster in the cadherin and cell adhesion functional groups (Benjamini p<0.00001). Hypermethylation of CDH11 (p=0.0143), COL5A1 (p=0.0127) and TNF (p=0.0098) and hypomethylation of NCAM1 (p=0.0158) was associated with altered mRNA expression in preterm PE placentas. These studies demonstrate aberrant methylation, correlating with disease severity, in PE placentas. Bisulphite converted DNA from the 45 samples were hybridised to the Illumina Infinium 450k Human Methylation Beadchip v1.2

A comparison of genome-wide DNA methylation patterns between different tissues from patients with coronary heart disease

Project description:Using the Illumina Infinium Human Methylation27 BeadChip, we performed a genome-wide analysis of DNA methylation in right coronary artery in the area of advanced atherosclerotic plaques, atherosclerotic-resistant internal mammary arteries, and great saphenous veins obtained from same patients with coronary heart disease. The resulting DNA methylation patterns were markedly different between all the vascular tissues. The genes hypomethylated in athero-prone arteries to compare with atherosclerotic-resistant arteries were predominately involved in regulation of inflammation and immune processes, as well as development. The great saphenous veins exhibited an increase of the DNA methylation age in comparison to the internal mammary arteries. Gene ontology analysis for genes harboring hypermethylated CpG-sites in veins revealed the enrichment for biological processes associated with the development. Four CpG-sites located within the MIR10B gene sequence and about 1 Kb upstream of the HOXD4 gene were also confirmed as hypomethylated in the independent dataset of right coronary arteries in the area of advanced atherosclerotic plaques in comparison with the other vascular tissues. Bisulfite converted genomic DNA from 24 samples was denatured, whole-genome amplified, fragmented and subsequently hybridized to the Illumina Infinium 27k Human Methylation Beadchip.

An Inhibitor of Mutant IDH1 Delays Growth and Promotes Differentiation of Glioma Cells Methylation Data for Xenograft Samples

Project description:The recent discovery of mutations in metabolic enzymes has rekindled interest in harnessing the altered metabolism of cancer cells for cancer therapy. One potential drug target is isocitrate dehydrogenase 1 (IDH1) which is mutated in multiple human cancers. Here, we examine the role of mutant IDH1 in fully transformed cells with endogenous IDH1 mutations. A selective R132H-IDH1 inhibitor (AGI-5198) identified through a high-throughput screen dose-dependently blocked the ability of the mutant enzyme (mIDH1) to produce R-2-hydroxyglutarate (R-2HG). Under conditions of near complete R-2HG inhibition, the mIDH1 inhibitor induced demethylation of histone H3K9M3 and expression of genes associated with gliogenic differentiation. Blockade of mIDH1 impaired the growth of IDH1-mutant - but not IDH1-wildtype – glioma cells without appreciable changes in genome wide DNA methylation. These data suggest that mIDH1 may promote glioma growth through mechanisms beyond its well-characterized epigenetic effects. Xenograft experiments were carried out with treatment cohorts of vehicle, 150mg/kg/day, 450mg/kg/day. After the indicated tumors were harvested and genomic DNA was extracted and analyzed by the Illumina 450k Methylation array.

Aberrant DNA methylation profiling of classic Philadelphia Negative Myeloproliferative Neoplasms

Project description:Since most DNA methylation studies in Classic Philadelphia-negative myeloproliferative neoplasms (MPNs) M-bM-^@M-^S polycythaemia vera (PV), essential thrombocythaemia (ET), and primary myelofibrosis (PMF) - have been performed on a gene-by-gene basis, a more comprehensive methylation profiling is needed to know the real implication of this alteration. In order to investigate the DNA methylation profile in chronic and transformed phase MPNs, we performed genome-wide DNA methylation arrays in 71 chronic (24 PV, 23 ET and 24 PMF) and 13 transformed MPNs. The three types of chronic MPNs showed the same aberrant DNA methylation pattern when compared to controls. Differentially methylated genes (DMG) were enriched in a gene network centered on the NF-M-NM-:B pathway, indicating that they may be involved in the pathogenesis of these diseases. In the case of transformed MPNs we detected an increased number of DMGs with respect to chronic MPNs. Interestingly, these genes were enriched in a list of DMGs in primary AMLs and in a gene network centered around the IFN pathway. Further studies are clearly needed to elucidate the role of DMGs in MPNs, but our results suggest that this alteration plays an important role in the pathogenesis and transformation of MPNs and that modulation of these pathways would allow us to improve the quality of life of these patients. The methylation profile of 24 PBMCs samples from patients diagnosed with Policytemia Vera, 23 from Essential Thrombocythemia and 24 from primary myelofibrosis was assessed. We also included 13 secondary acute myeloid leukaemia (AML): 5 transformed PMF,4 transformed TE and 4 transformed PV. As reference,4 healthy donor PBMCs samples from whole peripheral blood and 4 PBMCs samples from bone marrow were used.

Epigenetic regulation of the homeobox gene MSX1 associates with platinum resistant disease in high grade serous epithelial ovarian cancer

Project description:Introduction: Although High Grade Serous Ovarian Cancer (HGSOC) is considered a chemo-responsive disease, a proportion of patients do not respond to platinum-based chemotherapy at presentation or have progression-free survival of <6 months. Validated biomarkers of lack of response would enable alternative treatment stratification for these patients and identify novel mechanisms of resistance. Methods: Differential DNA methylation was investigated in independent tumour sets using Illumina 27K HumanMethylation arrays and validated by bisulphite pyrosequencing. Gene expression was by Affymetrix arrays and qRT-PCR. The role of Msh homeobox 1 (MSX1) in drug sensitivity was investigated by gene reintroduction into ovarian cancer cell lines. Results: CpG sites at contiguous genomic locations within the MSX1 gene have significantly lower levels of methylation in HGSOC which recur by 6 months compared to after 12 months and/or with RECIST response (p<0.05, q<0.05). A decrease in methylation at these intragenic CpG sites was significantly correlated with decreased MSX1 gene expression. Low expression of MSX1 was associated with poor progression-free survival independent of known clinical prognostic features (p=0.014). Three mutant or wild-type TP53 expressing ovarian cancer cell lines, resistant to cisplatin, have reduced MSX1 expression compared to matched parental, platinum sensitive, lines. Re-expression of MSX1 in resistant lines led to cisplatin sensitisation, increased apoptosis, increased p21 and BAX expression. However, in two TP53-null cell lines, MSX1 failed to change cisplatin sensitivity. Conclusion: Hypomethylation of MSX1 is a biomarker of resistant HGSOC disease at presentation and identifies a novel mechanism of platinum drug resistance. Bisulphite converted DNA from the 86 samples were hybridised to the Illumina Infinium 27k Human Methylation Beadchip v1.2
