Because Src is involved in the signaling pathway evoked by EGF and FGF-2 [43,44], and TAT-Cx43266–283 reduces Src activity in astrocytes and in glioma stem cells in vitro and in vivo [42,45], we aimed to confirm whether Src activity is also inhibited by TAT-Cx43266–283 in PC NPCs. Here, SRC is linked to central nervous system cancer.
