Interestingly, we also observed up-regulation of S-phase genes, as well as ribosomal genes involved in translation.
We found an up-regulation of NKG2C with a balanced differential expression of 5.8 in cDNA microarray (Fig.
In cultured human muscle cells, only the PI 3-kinase - p70 S6 kinase pathway, and not the MAPK pathway, mediates insulin up-regulation of p85α PI 3-kinase gene expression [ 26 ] . Similarly, in L6 myotubes, insulin induces hexokinase II gene transcription via the rapamycin-sensitive PI 3-kinase pathway, but not via the MAPK pathway [ 27 ] . The PI 3-kinase - p70 S6 kinase pathway, but not the MAPK pathway, mediates insulin induction of glucose-6-phosphate dehydrogenase gene expression in primary rat hepatocytes [ 28 ] . In H411E liver cells, insulin down-regulates cAMP-induced phosphoenolpyruvate carboxykinase gene transcription via the PI 3-kinase pathway, but not via the MAPK pathway [ 29 ] . Phosphorylated p70 S6 kinase has been shown to be present in the nucleus in insulin-treated cells [ 30 ] . Moreover, it has been shown that p70 S6 kinase phosphorylates and activates members of the cAMP response element modulator family of transcription factors [ 31 ] . These data raise the possibility that transcriptional regulation of SP-A gene expression occurs via the PI 3-kinase - p70 S6 kinase pathway.
Consistent with our microarray results on CCR5 up-regulation, experiments performed in peripheral blood mononuclear cells (PBMCs) with soluble Tat has shown selective entry and replication of CCR5 virus into cells [ 27 28 ] . Up-regulation of HIV-1 coreceptor by Tat has also been reported, where a synthetic Tat protein that was immobilized on a solid substrate, up-regulated the surface expression of the chemokine receptors in purified populations of primary resting CD4+ T cells.
5Bshows that despite increased basal p70 S6 kinase phosphorylation, insulin caused an additional up-regulation of p70 S6 kinase on Thr389 after incubation with insulin for 15 min to 16 hours.
