1 We found an inverse correlation between the intensity of ERK activity and the degree of AMPK activation after stimulation with either glucose deprivation or metformin. Metformin mitogen-activated protein kinase 1 Homo sapiens
2 We also found that the inhibition of ERK activity by U0126 restored AMPK activation after metformin treatment. Metformin mitogen-activated protein kinase 1 Homo sapiens
3 Importantly, metformin induced ERK activation by suppressing the protein levels of dual specificity phosphatase 6, a negative regulator of ERK. Metformin mitogen-activated protein kinase 1 Homo sapiens
4 Importantly, metformin induced ERK activation by suppressing the protein levels of dual specificity phosphatase 6, a negative regulator of ERK. Metformin mitogen-activated protein kinase 1 Homo sapiens
5 This crosstalk between AMPK and ERK could diminish the antileukemic activity of metformin. Metformin mitogen-activated protein kinase 1 Homo sapiens
