Non-Small Cell Lung Cancer can be Detected and its Subtypes Differentiated by a Blood Test of Methylation in Cell-Free DNA from PlasmaIntroduction: Non-small cell lung cancer (NSCLC)-related mortality is a major health hazard in the world. Current detection modalities rely on imaging, which ...
The blood test, also known asGalleri, uses next-generation sequencing and machine-learning algorithms to analyze methylation patterns of cell-free DNA (cfDNA) in the bloodstream, which can carry cancer-specific information. DNA methylation is a process used by cells to regulate gene expression. If...
The team found that looking at methylation patterns at around 1 million sites in DNA was the most promising approach. Methyl groups are chemical tags added to genes to inactivate them, and DNA from cancer cells has abnormal methylation patterns. Advertisement Next, the team trained a mac...
The immune system can monitor tumor development, and DNA methylation is involved in the body’s immune response to tumors. In this work, we investigate whether DNA methylation alterations in peripheral blood mononuclear cells (PBMCs) could be used as markers for early detection of breast cancer (...

DNA methylation (DNAm) has been implicated in acute coronary syndrome (ACS), but the causality remains unclear in cross-sectional studies. Here, we conduct a prospective epigenome-wide association study of incident ACS in two Chinese cohorts (discovery:
Sensitive Detection of Colorectal Cancer in Peripheral Blood by Septin 9 DNA Methylation Assay Colorectal cancer (CRC) is the second leading cause of cancer deaths despite the fact that detection of this cancer in early stages results in over 90% sur... R Grützmann,B Molnar,C Pilarsky,......
19 We assessed heterogeneity of effect estimates between strata of races, sexes, and methylation tissue source among discovery cohorts using a 1 degree of freedom chi-square test for effect differences between strata; no heterogeneous effects were observed so all cohorts were included in a single ...
Fig. 1: Miami plot for epigenome-wide meta-analysis of blood DNA methylation in ADNI and AIBL datasets. The X-axis shows chromosome numbers. The Y-axis shows –log10(P-value) of methylation to AD diagnosis association in the blood (above X-axis) or methylation to AD neuropathology (Braak...
The regulatory features with the greatest overrepresentation in the pleiotropic variants were the binding of RNA polymerase II (POL2) and the tri-methylation of the fourth lysine residue of histone H3 (H3K4me3), which marks transcription start sites of active genes (Fig. 4b and Additional file ...
