of the Wnt pathway inhibitor Lipoxygenin. Lipoxygenin is a non-redox 5-LO inhibitor, modulates the β-catenin-5-LO complex and induces reduction of both β-catenin and 5-LO levels in the nucleus. Lipoxygenin and the structurally unrelated 5-LO inhibitor CJ-13,610 promote cardiac differentiation of human induced pluripotent stem cells and inhibit Hedgehog, TGF-β, BMP, and Activin A signaling, suggesting
在基于细胞的筛选中鉴定和鉴定具有生物活性的小分子的靶标具有挑战性,并且常常遇到失败,因此需要开发新的方法。我们证明,化学蛋白质组学在使用SPiDER方法进行的计算机靶标预测中的组合可以为目标候选物的选择和实验深度评估的优先级提供有效的指导。我们确定5-脂氧合酶(5-LO)作为Wnt通路抑制剂脂氧合蛋白的目标。脂氧合蛋白是一种非氧化还原的5-LO抑制剂,可调节β-catenin-5-LO复合物并诱导细胞核内β-catenin和5-LO含量降低。脂氧合蛋白和与结构无关的5-LO抑制剂CJ-13,610促进人诱导的多能干细胞的心脏分化,并抑制刺猬,TGF-β,BMP,
