To asses if NaVP together has an effect on glioblastoma cell viability/proliferation in the presence and absence of Sema3C expression, tetracycline-induced and non-induced U87t-Sema3C cells were treated with different concentrations of NaVP (0–4 mM) over 72 h and the MTT assay was carried out. The gene discussed is SEMA3C; the disease is glioblastoma.
