Inhibitory effects of Pfaffia paniculata (Brazilian ginseng) on preneoplastic and neoplastic lesions in a mouse hepatocarcinogenesis model.

abstract：:RNA interference (RNAi) is an evolutionary conserved mechanism for specific gene silencing. There are currently numerous cancer therapy clinical trials based on RNAi technology. Using an adenoviral system as a delivery mediator of RNAi, we investigated the therapeutic effects of targeting three genes simultaneously in...
