TTFields downregulate genes important for DNA damage repair1,2

Double-strand break as a result of TTFields-induced disruption of DNA damage repair

TTFields downregulate genes important for DNA replication, chromosome structure, and DNA damage response in cancer cells.1,2

Watch below to see how TTFields disrupt DNA damage repair

Evidence has proven TTFields' ability to disrupt DNA damage repair by downregulating genes that are part of the well known FA-BRCA pathway.1,2
