ROR1 and breast cancer: We also saw this effect with larger concentrations of rWNT5A when cells were treated for 24hrs or more (S7 Fig) but our results show the efficacy of the LGK974 inhibitor and the Ror1 blocking antibody in reversing Dex mediated migration, suggesting that WNT5A may be a component of Dex mediated effects in select BC cell lines.
