Common biological signals

Regulators of G protein signaling (RGS) proteins modulate G protein-coupled receptor (GPCR) signaling networks by terminating signals produced by active Gα subunits. RGS17, a member of the RZ subfamily of RGS proteins, is typically only expressed in appreciable amounts in the human central nervous system, but previous works have shown that RGS17 expression is selectively upregulated in a number of malignancies, including lung, breast, prostate, and hepatocellular carcinoma.

Acidic extracellular pH is a common feature of tumor tissues. We have reported that culturing cells at acidic pH (5.4–6.5) induced matrix metallo-proteinase-9 expression through phospholipase D, extracellular signal regu-lated kinase 1⁄2 and p38 mitogen-activated protein kinases and nuclear factor-jB.

InArabidopsis thaliana, the serine⁄threonine protein kinase oxidative signal-inducible 1 (OXI1), mediates oxidative stress signalling. Its activity is required for full activation of the mitogen-activated protein kinases (MAP-Ks), MPK3 and MPK6, in response to oxidative stress.
