PTK2 and posterior cortical atrophy: Prior studies have revealed that NF‐κB, FAK, JAK1/2, ETK, JNK, MAPK, and PI3K‐Akt signaling pathways were involved in processes: cell growth, migration, invasion, angiogenesis, and apoptosis in CML and PCa (Figure 6B).26, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40 Liao et al41 discovered that PCa and CML were related to apoptosis by tyrosine kinases treating.
