The Wnt-PCP signalling pathway acts through RhoA and ROCK26, and can be inhibited pharmacologically, for example, with fasudil24, a ROCK inhibitor that is in clinical use for the treatment of cerebral vasospasm. PubMed:30232325
Comparison of signalling activity and Aβ production under each of the different conditions showed clearly that Aβ production was negatively correlated with Wnt-β-catenin signalling activity (Fig. 2d) and positively correlated with Wnt-PCP signalling (Fig. 2e). PubMed:30232325
APP has previously been shown to interact with Vangl2, a Wnt-PCP-specific co-receptor protein, and independently has been shown to bind LRP6, a receptor component of the Wnt-β-catenin pathway21. PubMed:30232325
In contrast, the stimulatory effects of Dkk1 on WntPCP signalling induced by Wnt5a were enhanced by APP overexpression, decreasing the EC50 of Dkk1 to 599ng/ mL from 1405ng/mL (Fig. 2g). PubMed:30232325
Conversely, the ability of APP to potentiate Wnt-PCP signalling in response to Wnt5a was enhanced by Vangl2 and attenuated by LRP6 (Fig. 1h). PubMed:30232325

APP did though potentiate both Wnt3a-driven Wnt-β-catenin signalling and Wnt5a-driven Wnt-PCP signalling. PubMed:30232325
In cells expressing either wild-type or Swedish APP, the amount of Aβ produced was reduced in cells stimulated with Wnt3a, which promotes Wnt-βcatenin signalling, whereas Aβ production was enhanced in cells stimulated with Wnt5a, which promotes Wnt-PCP signalling (Fig. 2c). PubMed:30232325
