SOX9 and glioblastoma: Although CMPD1 inhibited cell proliferation at certain concentrations (1–5 μM) in studied glioblastoma cells [22], it totally abrogated proliferation capacity of gastric cell lines MKN-45 and SGC7901 at a very low concentration (300 nM), indicating a better sensitivity of gastric cancer cells to CMPD1 treatment.
