    Abstract: The present invention relates to a method, in particular an in vitro method, for identifying monocytes, comprising analyzing the methylation status of at least one CpG position in the mammalian gene region for parkin RBR E3 ubiquitin protein ligase (PARK2), wherein a de-methylation or lack of methylation of said gene region is indicative for a monocyte, when compared to a non-monocyte cell. The analyses according to the invention can identify monocytes on an epigenetic level and distinguish them from all other cells in complex samples, such as, for example, other blood or immune cells. The present invention furthermore provides an improved method for quantifying monocytes, in particular in complex samples. The method can be performed without a step of purifying and/or enriching cells, preferably in whole blood and/or non-trypsinized tissue. Also claimed are kits and specific oligonucleotides for use as primers or probes.

    Abstract: β-cell loss in In Type 1 diabetes is typically undetected until the development of hyperglycemia, at which point β-cell mass is significantly reduced. Methylation sensitive quantitative real time PCR (qRTPCR) of demethylated circulating free β-cell specific DNA can be used as a biomarker of β-cell death. Such DNA includes insulin gene and amylin gene DNA. Detection may be by determination of a gene demethylation index. Methylated and demethylated DNA may be distinguished by bisulfite treatment and use of specific PCR primers or probes to detect the different bisulfite treatment products. Detection of demethylated circulating free amylin DNA is useful in identifying β-cell death. The amylin DNA may be used in conjunction with other β-cell specific genes, such as insulin, to provide a multi-gene approach towards the detection of β-cell loss.

    Abstract: The present invention provides methods and materials related to the detection of colorectal neoplasm-specific markers (e.g., markers associated with colorectal cancer, markers associated with adenoma) in or associated with a subject's stool sample. In particular, the present invention provides methods and materials for identifying mammals (e.g., humans) having a colorectal neoplasm by detecting the presence and level of indicators of colorectal neoplasia such as, for example, long DNA (e.g., quantified by Alu PCR) and the presence and level of tumor-associated gene alterations (e.g., mutations in KRAS, APC, melanoma antigen gene, p53, BRAF, BAT26, PIK3CA) or epigenetic alterations (e.g., DNA methylation) (e.g., CpG methylation) (e.g., CpG methylation in coding or regulatory regions of bmp-3, bmp-4, SFRP2, vimentin, septin9, ALX4, EYA4, TFPI2, NDRG4, FOXE1) in DNA from a stool sample obtained from the mammal.
