Do voriconazole N-oxide and its ultraviolet B photoproduct sensitize keratinocytes to ultraviolet A?
Voriconazole N-oxide and its UVB-photoproduct act as UVA-sensitizers that generate ROS and that produce oxidative DNA damage. These results suggest a mechanism for the phototoxicity and photocarcinogenicity observed with voriconazole treatment.
Activated Smad signaling might be associated with a high potential for peritoneal recurrence in CY1P0 patients. Borrmann's macroscopic criteria and p-Smad2 expression are useful markers for surgeons selecting advanced gastric cancer patients with CY1P0 for gastrectomy.
