neoplasm
• infiltrating inflammatory cells recruited to tumors in which NF-kB has been inhibited
• tumorigenesis is initiated by infection with lentiviruses expressing Cre and Nfkbia lentiviruses
• doxycycline (Dox)-mediated induction of Nfkbia expression specifically in the tumor cells starting at 16 weeks after tumor initiation results in a significantly diminished tumour growth rate
• tumorigenesis is initiated by infection with lentiviruses expressing Cre and Nfkbia lentiviruses
• doxycycline (Dox)-mediated induction of Nfkbia expression specifically in the tumor cells leads to a significant impairment of tumour development
• tumorigenesis is initiated by infection with lentiviruses expressing Cre and Nfkbia lentiviruses
