Cancer doesn’t always begin with genetic mutations: simply
turning a gene off is enough.
Studies with mice has provided the first evidence that turning a
gene on or off can cause cancer. The study gives hope on how
epigenetic engineering (deliberately turning genes on and off)
can be used to study predisposition to diseases and prevent it.
While an individual’s DNA remains unchanged through life,
epigenetic alterations influence how their DNA sequence is
read. This includes switching particular genes on or off, which
can cause cancer.
Researchers at the Children’s Nutrition Research Center at
Baylor College of Medicine and Texas Children’s Hospital have
shown how epigenetic changes can lead to cancer in mice.
Their report appears in the Journal of Clinical Investigation.
The team focused on p16 – a gene known to prevent cancer –
but is common in many human cancers. Engineering a process
called ‘methylation’ in the gene led to a higher incidences of
spontaneous cancers, and reduced survival rates in the mice.
There are other genes connected to other diseases – including
neuro-developmental diseases, obesity and diabetes – which
allow for epigenetic engineering.
Understanding the epigenetic changes that predispose people
to the diseases, they can be prevented, say scientists.
