Biochemical signaling in MZCRC1 and TT cells after exposure to cabozantinib. (A) MZCRC1 cells were exposed to the indicated compounds, and Western blots were performed on cell lysates. (B) TT cells were exposed to the indicated compounds, and Western blots were performed on cell lysates. Representative image from three independent experiments. For the 24 + 1 treatment condition, fresh drug was added after 24 h of exposure, and a lysate was prepared after 1 h.
