SEMA4F and glioblastoma: The gene ssemaphorin 4F (SEMA4F, Gene ID: 10505) encodes a transmembrane class IV semaphorin family protein, which plays a role in neural development (Gabrovska et al., 2011; Shergalis et al., 2018), and the previous study found that SEMA3B was found to be a marker for poor survival in patients over 50 diagnosed with GBM (Rich et al., 2005).
