ROR2 is a Wnt co-receptor with established pro-tumorigenic roles in cancer cell invasion and metastasis. In colorectal adenocarcinoma, high ROR2 expression correlates with poor prognosis and advanced TNM stage. By studying its interactome with co-immunoprecipitation and mass spectrometry, we identified new binding partners, including JAK1 and JAK2, and showed that ROR2 amplifies IFNγ-JAK/STAT signaling, leading to increased expression of immune-related molecules such as PD-L1 and IDO1. These results suggest that, beyond its intrinsic effects on cancer cells, ROR2 may also reshape the tumor immune microenvironment.
