Tumor tissue lysates from CT26 cells that received exosomes from the CT26Flag−CAGE1 cells displayed increased FcεRIβ expression, and interactions of FcεRIβ with SOCS1 and Lyn (Figure 12B) compared to the tumor tissue lysates of CT26 cells that received CT26 exosomes. The gene discussed is SOCS1; the disease is neoplasm.
