This study suggests that loss of PER2 contributes to cisplatin resistance in SKOV3 cells, possibly by activating the PI3K/AKT pathway and EMT, inhibiting apoptosis, and promoting drug efflux and inflammatory responses. Overexpression of PER2 could reverse these alterations and sensitize both parental SKOV3 and SKOV3/DDP cells to cisplatin.
