Given this wealth of choices, common practice is to limit synthesis to only those compounds estimated to have the greatest chance of being high-affinity binders; of the many potential factors contributing to this estimation, the strength of the selection signal of a candidate binder is always important. We define here methods and equations which relate the theoretical selection signal of a compound to its affinity and chemical yield. Tests using known binders of BRD4 and ROCK2 support the theory backing these equations and suggest they should be of use for prospectively determining affinity and chemical yield from primary DEL selection data.Intratumoral heterogeneity remains as a major challenge in the treatment resistance of prostate cancer. Understanding the mechanism of prostate cancer heterogeneity is essential for developing effective therapies. In this study, we reported the heterogeneous activation of Wnt/β-catenin signaling in prostate cancer. We developed a Wnt/β-catenin signaling reporting system to directly characterize the differences between Wnt/β-catenin signaling active (GFP+) and inactive (GFP-) cells. Compared to GFP- cells, GFP+ cells demonstrated cancer stem cell properties with higher colony formation efficiency, slower cell cycle, higher resistance to docetaxel and higher expression of cancer stem cell markers. In addition, we found that Wnt/β-catenin signaling is negatively correlated with H3K27me3 levels. Further studies demonstrated that Wnt/β-catenin signaling affected H3K27me3 levels by regulating the expression of KDM6A, one of the H3K27me3 demethylases. H3K27me3 suppressed Wnt/β-catenin signaling by directly silencing LEF1 promoter. Together, o
