Korov., has been reported to trigger glioma cell apoptosis in vitro.19 Here, we show that DAW22 could inhibit cell proliferation in both sporadic (STS‐26T) and NF1‐associated (S462, S462‐TY, ST8814, and T265) MPNST cell lines. The gene discussed is NF1; the disease is malignant peripheral nerve sheath tumor.
