General Comments
EZH1/2 inhibitors have anti-proliferative effects that have anti-cancer potential. In addition, pharmacological inhibition of EZH1 and EZH2 has been shown to induce multiple inflammatory, stress, and antipathogen pathways, and to enhance recruitment of immune cells to virally infected cells in vitro, thereby creating a cellular antiviral state that was suppressive to infection by a range of DNA and RNA viruses [2]. EZH1/2 inhibitors exhibiting this experimental effect were GSK126, GSK343 and UNC1999. This work suggests that EZH1/2 inhibitors can induce a general antiviral defense mechanism.
