Impressed with the suppressed tumor growth and cell proliferation after QDSJ treatment, and the tumor angiogenesis-related proteins, including EGFR, FGF1, FGF2, VEGRR2, and PDGFRA revealed in the top 15 key targets in the PPI network of QDSJ decoction treating NF2-associated VS, we hypothesized that QDSJ decoction would attenuate tumor angiogenesis of the NF2-associated VS. The gene discussed is PDGFRA; the disease is neoplasm.
