1 BACKGROUND: The potential utility of 5"-adenosine monophosphate-activated protein kinase (AMPK)-activating agents, such as metformin, in inducing angiogenesis, could be a promising approach to promote healing of gastric ulcers complicated by diabetes mellitus. Metformin protein kinase AMP-activated catalytic subunit alpha 2 Rattus norvegicus
2 BACKGROUND: The potential utility of 5"-adenosine monophosphate-activated protein kinase (AMPK)-activating agents, such as metformin, in inducing angiogenesis, could be a promising approach to promote healing of gastric ulcers complicated by diabetes mellitus. Metformin protein kinase AMP-activated catalytic subunit alpha 2 Rattus norvegicus
3 The aim of the present study was to assess the effect of a drug that activates AMPK, namely metformin, in gastric ulcer healing in streptozotocin-induced diabetic rats. Metformin protein kinase AMP-activated catalytic subunit alpha 2 Rattus norvegicus
4 RESULTS: Administration of metformin, but not pioglitazone, resulted in a significant decrease in the gastric ulcer area, a significant increase in epithelial regeneration assessed histologically, a significant increase in the number of microvessels in the ulcer margin, a significant increase in gastric vascular endothelial growth factor concentration and gastric von Willebrand factor as well as a significant increase in gastric phospho-AMPK. Metformin protein kinase AMP-activated catalytic subunit alpha 2 Rattus norvegicus
5 Compound C, an inhibitor of AMPK, blocked metformin-induced changes in assessed parameters suggesting that the effect of metformin was mediated mainly through activation of AMPK. Metformin protein kinase AMP-activated catalytic subunit alpha 2 Rattus norvegicus
6 Compound C, an inhibitor of AMPK, blocked metformin-induced changes in assessed parameters suggesting that the effect of metformin was mediated mainly through activation of AMPK. Metformin protein kinase AMP-activated catalytic subunit alpha 2 Rattus norvegicus
7 Compound C, an inhibitor of AMPK, blocked metformin-induced changes in assessed parameters suggesting that the effect of metformin was mediated mainly through activation of AMPK. Metformin protein kinase AMP-activated catalytic subunit alpha 2 Rattus norvegicus
8 Compound C, an inhibitor of AMPK, blocked metformin-induced changes in assessed parameters suggesting that the effect of metformin was mediated mainly through activation of AMPK. Metformin protein kinase AMP-activated catalytic subunit alpha 2 Rattus norvegicus
