Figure 6. PVT1 stimulates exosome secretion via palmitoylation of YKT6. (A) The level of palmitoylation of YKT6 in PVT1-overexpressing HS766T cells. (B) The level of palmitoylation of YKT6 in PVT1-overexpressing HS766T cells treated with Digitonine (control) or Triton X-100 (palmitoylation inhibitor). (C) The concentration of exosomes derived from PVT1-overexpressing HS766T cells treated with Digitonine (control) or Triton X-100 (palmitoylation inhibitor). *P < 0.05, data are expressed as the mean ± SD.
