They analyzed the behavior of two tumor-suppressing genes, p16 and FHIT, that are silenced or damaged in the early stages of cancer development, and tracked whether the genes were silenced by methylation, the attachment of a chemical methyl group to an atom or molecule, which in this case, eventually leads to the function of a gene shutting down.
