Researchers clock DNA’s recovery time after chemotherapy

July 12, 2019 dna 0
A team of researchers found that DNA damaged by the widely used chemotherapy drug cisplatin is mostly good as new in noncancerous tissue within two circadian cycles, or two days. The results could inform the development of chronochemotherapies — strategies aimed at administering chemotherapy drugs at times that maximize tumor damage while minimizing side effects.

Scientists invent fast method for ‘directed evolution’ of molecules

July 12, 2019 dna 0
Scientists demonstrated the technique by evolving several proteins to perform precise new tasks, each time doing it in a matter of days. Existing methods of directed evolution are more laborious and time-consuming, and not in human cells, which limits the usefulness of this technology for research and developing new therapeutics.
