RTCB and neoplasm: Immunohistochemical and immunoblotting analyses showed that PT treatment downregulated cell cycle–related proteins (p-histone H3 in A2058 and NB-1 models; cyclin D1 in the NB-1 model), glycoprotein (NRP1 in the A2058 model), and focal adhesion-associated protein (p-FAKY397 in the NB-1 model) in the tumor tissues (Supplemental Figures 9 and 10), although the other proteins investigated were not significantly different.
