ZM fusion in training and validation sets. (A) Schematic of PTPRZ1, MET, and the resulting PTPRZ1-MET fusion proteins. (B) PCR and Sanger sequencing validation of the positive fusion samples in the training and validation sets. (C) ZM fusion screening in 19 glioma cell lines. Three cell lines (U118, LN18, and CMK3) showed as ZM fusion positive.
