Vangl1 Inhibitors

Vangl1 inhibitors predominantly target the Wnt/planar cell polarity (PCP) pathway, a key signaling cascade involved in regulating cell polarity and directional cell movement. The inhibitors listed above, although not directly inhibiting Vangl1, function by modulating various components of the Wnt/PCP and Wnt/β-catenin pathways, which are closely related to the function of Vangl1. These inhibitors typically work by either stabilizing or destabilizing key proteins in the pathway, altering the secretion and activity of Wnt proteins, or disrupting protein-protein interactions essential for pathway activation.

The chemical inhibitors target different stages of the Wnt signaling cascade. For instance, compounds like ICG-001 and XAV-939 function upstream by influencing β-catenin levels and activity, a pivotal component in Wnt signaling. LGK-974 and ETC-159 are examples of porcupine inhibitors, which block the secretion of Wnt ligands, thereby affecting the Wnt/PCP pathway indirectly. Other inhibitors like KY1220, IWR-1, and JW55 modulate the pathway by affecting the stability and interaction of key signaling molecules like Axin and β-catenin. FH535 and PKF118-310 demonstrate broader activity by targeting both Wnt/β-catenin and other related pathways, indicating a multi-faceted approach to modulating Vangl1 activity. These inhibitors play a crucial role in research focused on understanding the Wnt/PCP pathway and its implications in cellular processes. Their use extends to studying disorders related to cell polarity and movement, providing valuable insights into the underlying mechanisms of these conditions.
