Overview of Gene Research
Fbh1, or F-box DNA helicase 1, is a member of the UvrD family of DNA helicases. It plays crucial roles in the DNA damage response and the regulation of cell responses to replicative stress [3,4,6]. FBH1 is involved in pathways related to homologous recombination, replication fork processing, and checkpoint control, which are essential for maintaining genome integrity [2,3,7].
FBH1-deficient cells show a reduction in ssDNA and double-strand break signaling, indicating its requirement for the induction of replication stress response in cells treated with WEE1 inhibitors. Despite this defect, FBH1-deficiency sensitizes cells to WEE1 inhibition by increasing mitotic catastrophe, suggesting that loss of FBH1 leads to replication-associated damage that needs the WEE1-dependent G2 checkpoint for repair [1,5]. Also, FBH1 depletion promotes UV-mediated transformation of human melanocytes, and its inactivation may contribute to oncogenic transformation [6].
In conclusion, FBH1 is vital for maintaining genome integrity through its functions in replication stress response, homologous recombination regulation, and checkpoint control. The study of FBH1-deficient models has revealed its significance in cancer-related processes, such as oncogenic transformation and response to WEE1 inhibition, providing insights into potential cancer therapeutic strategies.
