CDC42BPA and pancreatic neoplasm: Drug combinations to simultaneously block several targets may produce greater anti-metastatic effects: combined inhibition of ROCK and Rac reduced mesenchymal motility of Y27632 treated gastric cancer cells (Matsuoka and Yashiro 2014; Matsuoka et al. 2011); combined inhibition of ROCK and myotonic dystrophy kinase-related Cdc42-binding kinases (MRCK) inhibited migration and invasion of lung, breast, melanoma, and pancreatic cancer cells (Kale et al. 2014, 2015).
