1 AMP-activated protein kinase (AMPK), an important downstream effector of the tumor suppressor liver kinase 1 (LKB1) and pharmacologic target of metformin, is well known to exert a preventive and inhibitory effect on tumorigenesis; however, its role in cancer progression and metastasis has not been well characterized. Metformin serine/threonine kinase 11 Homo sapiens
2 The effect of metformin is dependent on the presence of LKB1. Metformin serine/threonine kinase 11 Homo sapiens
3 As a consequence, expression of genes downstream of Smad2/3, including plasminogen activator inhibitor-1, fibronectin, and connective tissue growth factor, was suppressed by metformin in a LKB1-dependent fashion. Metformin serine/threonine kinase 11 Homo sapiens
4 In addition, metformin blocked TGF-beta-induced inteleukin-6 expression through both LKB1-dependent and -independent mechanisms. Metformin serine/threonine kinase 11 Homo sapiens
