Effect of S956711 on the EGLN-dependent and Lck-dependent three-hybrid systems. Yeast clones transformed with constructs encoding for AD-P564 and E3/DB-VHL (E3) or AD-SH2 and Lck/DB-ITAM (Lck) were used to inoculate control media lacking Leu and Trp (control) or restrictive media (restrictive) lacking Leu, Trp, and His (in the case of E3 clones, restrictive media also lacked adenine). Duplicate cell cultures were grown in the presence of 0, 25, 50 or 100 μM S956711. The density of cultures was determined 16–24 hours after inoculation. A, The cell density (absorbance at 620 nm) of each culture condition is represented as the percentage of density obtained for the cells grown in the absence of drug. The graph represents the average values of nine independent experiments. Error bars represent the S.E.M. B, the individual data values of density for the 50 μM S956711 cultures in A are represented. Horizontal bars represent the mean. Statistically significant different mean values (p < 0.001) are indicated with asterisks.
