An epigenetic model of cancer that incorporates the concept of stochasticity could also explain why cancer risk increases with age and how biological development can be reversible.
When a male bluehead wrasse is removed from the group he dominates, the largest female changes sex, rapidly transforming ovaries into sperm-producing testes. Molecular research shows how.
Humans, and indeed pet dogs, are more than just products of genes – even before the moment of conception, environments play a vital role in shaping us.
The older we get, the higher our risk of cancer. With age, we accumulate exposure to environments and chemicals that increase the risk of acquiring cancer-causing mutations. But the danger doesn’t increase…
Thanks to the Human Genome Project we now have a complete genomic map. But, simply having a map doesn’t give you all the information. For a map to be useful, you still need know where to go, the best way…
