Identification of the genes responsive to etoposide-induced apoptosis: application of DNA chip technology.

abstract：:Polyphosphates (polyP) are long chains of inorganic phosphates that can be attached to lysine residues of target proteins as a nonenzymatic post-translational modification. This modification, termed polyphosphorylation, may be particularly prevalent in bacterial and fungal species that synthesize large quantities of p...

However, the orexigenic effect of ghrelin is mediated by the AMP-activated protein kinase (AMPK)-uncoupling protein 2 (UCP2) pathway. Here, we demonstrate that ghrelin's inhibitory effect on insulin secretion also occurs through the AMPK-UCP2 pathway...
