Vitamin K 3 33-42 sirtuin 7 Homo sapiens 79-115 35319066-5 2022 As assessed by their inhibitions of rDNA transcription, pre-rRNA processing and formation of etoposide-induced 53BP1 foci, menadione and plumbagin inhibit also Sirtuin 7 catalytic activity in vivo. Vitamin K 3 123-132 sirtuin 7 Homo sapiens 160-169 35319066-6 2022 Second, we have established that in experimental conditions in which the sulfhydryl arylation by menadione or plumbagin is prevented by the thiol reducing agent N-acetyl-L-cysteine, the inhibition of Sirtuin 7 catalytic activity is also prevented. Vitamin K 3 97-106 sirtuin 7 Homo sapiens 200-209
