Wnt5a, a non-transforming Wnt family member, plays complicated roles in oncogenesis and cancer metastasis. However, Wnt5a signaling in gastric cancer progression remains poorly defined. In this study, we found that Wnt5a dose-dependently stimulated the migration of human gastric cancer cells (SGC-7901), with the maximal effect at 100ng/mL, via enhancing phosphorylation of PI3K/Akt and GSK3β and activating...
Epidermal growth factor (EGF) may increase cell motility, an event implicated in cancer cell invasion and me-tastasis. However, the underlying mechanisms for EGF-induced cell motility remain elusive. In this study, we found that EGF treatment could activate Ras-related C3 botulinum toxin substrate 1 (Rac1), PI3K/Akt and p21-actived kinase (PAK1) along with cell migration. Ectopic expression of PAK1...
