PTPA and gastric cancer: Our previous studies have demonstrated that ZJW could significantly enhance the sensitivity of DDP-resistant gastric cancer cells to DDP and executed their biological effects by increasing mitochondrial apoptosis via PP1 and PP2A induced the dephosphorylation of p-cofilin-1, which implied that ZJW might serve as a synergistic drug with DDP in the treatment of gastric cancer [7].
