Abstract
The present invention relates to compositions and methods for detecting cell death by detecting cell DNA in a biological sample. The invention relates the discovery that the presence of hypomethylated β cell DNA outside of the pancreas of a subject is indicative of β cell death. Thus, in one embodiment, the invention is a method of detecting hypomethylated β cell insulin DNA in a biological sample of a subject including the steps of: obtaining a biological sample from the subject, where the biological sample is obtained from outside of the subject's pancreas and where the biological sample contains β cell insulin DNA; determining the methylation status of at least one of the CpG dinucleotides in the β cell insulin DNA, where when at least one of the CpG dinucleotides in the β cell insulin DNA is determined to be unmethylated, the hypomethylated β cell insulin DNA is detected.
