                                                    KY02111 is a canonical WNT signaling (β-catenin) inhibitor which promotes differentiation of hPSCs to cardiomyocytes. KY02111 can be used for the research of human cardiomyocyte regeneration.

                                                    To gain insight into how KY02111 promotes cardiac differentiation of hPSCs, gene expression profiles of IMR90-1 hiPSCs treated with KY02111 were analyzed using the microarray technique. KY02111 or DMSO was added to the culture on day 3 of cardiac differentiation, and the cell population was harvested after 12 or 24 hr. A total of 22 downregulated genes and four upregulated genes were identified at both 12 and 24 hr after KY02111 treatment (Figure 3A; Table S1). Although only a few genes were extracted by the microarray analysis, perhaps due to high heterogeneity of the cell population, the microarray data were validated by qPCR (Figure S4A). When the 22 downregulated genes were examined for common transcription factor-binding sites, using DiRE (Gotea and Ovcharenko, 2008), which can predict distant regulatory elements, TCF4 was predicted as a common transcription factor (Figure S4B). Of the 22 downregulated genes, 16 (72.7%) were known target genes of canonical WNT signaling (Table S1). Furthermore, the effect of KY02111 on WNT target gene expression was very similar to that of other WNT inhibitors, such as XAV939 and IWP-2, but not of BIO, a WNT activator (Figure S4C). These results suggested that KY02111 inhibits canonical WNT signaling in hPSCs.
