[Abstract]  Noncanonical Wnt signaling functions independently of the β-catenin pathway to control diverse developmental processes, and dysfunction of the pathway contributes to a number of human pathological conditions, including birth defects and metastatic cancer. Progress in the field, however, has been hampered by the scarcity of functional assays for measuring noncanonical Wnt signaling activity. We recently described the Wnt5a-Ror-Kif26b (WRK) reporter assay, which directly monitors a post-transcriptional regulatory event in noncanonical Wnt signaling. In this protocol, we describe the generation of the stable GFP-Kif26b reporter cell line and a quantitative reporter assay for detecting and measuring Wnt5a signaling activities in live cells via flow cytometry. [摘要]  非经典Wnt信号独立于β-catenin途径发挥功能来控制不同的发育过程,并且该途径的功能障碍导致许多人类病理状况,包括出生缺陷和转移性癌症。 然而,该领域的进展一直受到用于测量非典型Wnt信号活性的功能测定的稀缺性的阻碍。 我们最近描述了Wnt5a-Ror-Kif26b(WRK)记者测定法,其直接监测非典型Wnt信号传导中的转录后调节事件。 在该协议中,我们描述了通过流式细胞术检测和测量活细胞中Wnt5a信号传导活性的稳定GFP-Kif26b报告细胞系和定量记者测定法的产生。

【背景】从历史上看,转录报告基因检测方法促进了主要信号通路的描述。具体来说,β-连环蛋白依赖性萤光素酶或基于GFP的转录报道基因有助于阐明经典Wnt /β-连环蛋白途径的分子机制(Korinek et al。,1997; Fuerer and Nusse,2010)。尽管已经描述了许多基于JNK依赖性转录的非经典Wnt信号传导报道分子,但是这些转录应答是否是非经典Wnt信号传导的主要或次要仍不清楚(Veeman等,2003; Nishita等,等,2010; Ohkawara和Niehrs,2011)。此外,用于实时检测非转录性Wnt5a-Ror信号传导事件的记者尚未获得。 ...
