But a burgeoning field known as epigenetics is showing that many cancers may not be caused by mutations in genes, but by chemical modifications that alter how the genes function. Such modifications to genes are epigenetic-literally on top of or related to changes in the DNA sequence.
However, it is thought that between each generation the epigenetic marks are erased in cells called primordial gene cells (PGC), the precursors to sperm and eggs. This âreprogrammingâ allows all genes to be read afresh for each new person â leaving scientists to question how epigenetic inheritance could occur. The new Cambridge study initially discovered how the DNA methylation marks are erased in PGCs, a question that has been under intense investigation over the past ten years.
