β-ARRESTIN/CONNEXIN 43 (Cx43) complex anchors ERKS outside the nucleus: a prerequisite for bisphosphonate antiapoptotic effect mediated by Cx43/ERK in osteocytes

Actual. osteol; 12 (1), 2016
Bisphosphonates (BPs) anti-fracture efficacy may be due in part to inhibition of osteocyte apoptosis. This effect requires opening of connexin (Cx) 43 hemichannels and phosphorylation of the extracellular signal regulated kinases (ERKs). However, unlike ERK activation by other stimuli, the Cx43/ERK pathw...

Lessons from tumor and immunocompetent cells. The quantitative engagement of ligand-receptor interactions modulates stop-and-go behavior as well as proliferation

Medicina (B.Aires); 60 Suppl 2 (), 2000
The four main cell functions, proliferation, apoptosis, differentiation and migration, are tightly regulated by external signals that initiate intracellular signal transduction pathways and determine the cellular behaviour. The concentration and composition of such external signals are at least important...
