Uptake of alpha-methyl-aminoisobutyric acid (Me-AIB), a non-metabolisable System A substrate, was increased by between 50% and 80% when muscle cells were exposed to a maximally effective concentration of insulin (100 nM), sodium arsenite (ARS, 0.5 mM) or a 42 degrees C heat shock (HS).

Sodium arsenite and osmotic shock both stimulated stress-activated protein kinase-2 (SAPK2, also termed RK, p38, CSBP and Mxi2) and its downstream target mitogen-activated protein kinase (MAP kinase)-activated protein kinase-2 (MAPKAP-K2) in bovine adrenal chromaffin and rat PC12 cells.

These effects of glucose could be mimicked by chemical stress (sodium arsenite), or by overexpression of SAPK2 in the beta-cell line MIN6.

Termed SAKS1 (SAPK substrate-1), it was phosphorylated efficiently at Ser200 in vitro by SAPK3/p38gamma, SAPK4/p38delta and JNK (c-Jun N-terminal kinase), but weakly by SAPK2a/p38alpha, SAPK2b/p38beta2 or ERK (extracellular-signal-regulated kinase) 2.

We demonstrate that p38beta mitogen-activated protein (MAP) kinase augments ATF-2 transactivation activity on the PEPCK-C promoter, which is consistent with the interpretation that PEPCK-C promoter activity is maintained under stress through a p38 MAP kinase dependent pathway.
In this regard, we show that treatment with sodium arsenite, a known activator of p38 MAP kinases, also stimulates expression from the PEPCK promoter.

The selective inhibitor of stress-activated protein kinase 2 (SAPK2), SB 203580, inhibited completely anisomycin-induced glucose uptake but only partly suppressed uptake stimulated by arsenite.

Insulin and sodium arsenite, an activator of the stress-activated pathway, also stimulated PDX-1 movement from the nuclear periphery to the nucleoplasm.
Glucose and insulin regulate PDX-1 by way of a signaling pathway involving phosphatidylinositol 3-kinase (PI 3-kinase) and SAPK2/p38.
