Furthermore, tumor cell‐induced WT platelet P‐selectin (Figures 4B and S5A) and PS exposure (Figures 4C and S5B) and tumor cell–platelet interaction (Figures 4D,E and S6) were significantly inhibited by Gö6983 (an inhibitor of pan‐PKC) and Gö6976 (a specific inhibitor of PKCα and PKCβ1). Here, PRKCA is linked to neoplasm.
