Methods and compositions for differentiating tissues for cell types using epigenetic markers

The present invention provides, inter alia, a method for generating a genome-wide epigenomic map, comprising a correlation between methylation variable CpG positions (MVP) and genomic DNA sample types. MVP are those CpG positions that show a variable quantitative level of methylation between sample types. Particular genomic regions of interest (ROI) provide preferred marker sequences that comprise multiple, and preferably proximate MVP, and that have novel utility for distinguishing sample types. The epigenic maps have broad utility, for example, in identifying sample types, or for distinguishing between and among sample types. In a preferred embodiment the epigenomic map is based on methylation variable regions (MVP) within the major histocompatibility complex (MHC), and has utility, for example, in identifying the cell or tissue source of a genomic DNA sample, or for distinguishing one or more particular cell or tissue types among other cell or tissue types. Analysis of epigenetic characteristics of one, or of a set of nucleic acid sequences, in the context of an inventive epigenomic map, allows for the determination of an origin of the nucleic acids.

Hypermethylation Biomarkers for Detection of Cervical Cancer

Pap smears and HPV infection tests do not distinguish between lesions that will progress to an invasive carcinoma and those that will not. We aimed to identify epigenetic biomarkers for diagnosis and progression monitoring of premalignant lesions in cervical cancer. Hypermethylated genes were identified as potential biomarkers after validation by MSP, including GGTLA4 and ZNF516. The methylation frequency for these two genes was higher in tumor: GGTLA4 (100%) and ZNF516 (96%); than in normal samples: GGTLA4 (12%) and ZNF516 (16%). The methylation status of GGTLA4 showed a progression in methylation frequency from normal samples to invasive carcinoma. The immunohistochemical expression was lower in tumor for both: GGTLA4 (50.8%) and ZNF516 (66.2%); than in normal samples: GGTLA4 (71.2%) and ZNF516 (88.1%) (p<0.05). In conclusion, we identified methylation biomarkers for the molecular screening and characterization of cervical cancer.
