Angiotensin II (Ang II) is a critical regulator of insulin signaling in the cardiovascular system and metabolic tissues. However, in adipose cells, the regulatory role of Ang II on insulin actions remains to be elucidated. The effect of Ang II on insulin-induced insulin receptor (IR) phosphorylation, Akt activation, and glucose uptake was examined in 3T3-L1 adipocytes.

We found that Pertussis Toxin (PTX) treatment or sequestering Gβγ reduced CRFR-mediated activation of ERK1/2, suggesting the involvement of a G-linked cascade. Neither G/PKA nor G/PKC were associated with ERK1/2 activation.
