General description

A cell-permeable dihydrothiopyranopyrimidinol that binds TNKS1/PARP5a and TNKS2/PARP5b with high affinity (Kd = 99 and 93 nM, respectively) and potently inhibits their PARsylation (poly ADP-ribosylation) activity (IC50 = 11 and 4 nM, respectively), while exhibiting much lower activity against PARP1 and PARP2 (IC50 = 2.194 and 0.114 µM, respectively). TNKS, but not PARP1/2, function knockdown by siRNA or XAV939 treatment suppresses cellular axin1/2 PARsylation and ubiquitination/proteasomal degradation, resulting in axin build-up, β-catenin destruction, and blockage of Wnt signaling. XAV939 is shown to inhibit the growth of β-catenin-dependent DLD-1, but not that of β-catenin-independent RKO, cells (by >95% vs. no effect at 3.3 µM, respectively) in vitro and prevent the regeneration of zebrafish tail fin (by ~70% at 7 d post-amputation, 5 µM) after surgical removal in vivo.

Various culture methods have been developed for maintaining human pluripotent stem cells (PSCs). These PSC maintenance methods exhibit biased differentiation; for example, feeder-dependent PSCs efficiently yield cerebral organoids, but it is difficult to generate organoids from feeder-free PSCs.

The placenta is a highly evolved, specialized organ in mammals. It differs from other organs in that it functions only for fetal maintenance during gestation. Therefore, there must be intrinsic mechanisms that guarantee its unique functions. To address this question
