A Western blot analysis of WM266-4 cell lysates collected after 60 or 120 min of treatment with TRPM8 modulators, using the indicated antibodies. B WM266-4 cells were untreated (-) or treated for 120 min with TRPM8 antagonists (4 and 9, used at 10 µM). Lysate proteins were immune-precipitated using the anti-TRPM8 (anti-TRPM8) or control (ctrl IgG) antibodies. WB analysis using antibodies against the indicated proteins was done to reveal co-immunoprecipitated proteins. Western blot analysis of cleaved caspase-3 and cleaved PARP in AMM16 (C) and WM266-4 (D) cells treated with TRPM8 modulators at the indicated concentrations and hours. The α-tubulin was used as loading control. Graphs in the lower part of the figure represent the densitometric analysis of the cleaved PARP/tubulin ratio obtained in three different experiments (n = 3).
