Tada,
That is a poster from last year's AACR meeting focusing on the pre-clinical characterization of ZEN-3694. Figure 2 and 5 that you mention are in mouse xenograft models dosed with ZEN-3694. My comment "I think all we've seen so far is gene modulation 24 hours after administration of the lowest dose" referred to human dosing. Zenith collaborated with Eva Corey and Holly Nguyen from Univ. of Washington to do one of the xenograft models.
