Proliferation of fibroblasts is important for wound healing and reparation. Platelet-derived growth factor (PDGF) is a key regulator of this activity in fibroblasts. Activation of the PDGF receptor is also associated with endogenous generation of hydrogen peroxide (H2O2). Here we studied the involvement of H2O2 in the proliferative response of fibroblasts. We found that PDGF increased cytoplasmic...
Cell chemotaxis plays a pivotal role in normal development, inflammatory response, injury repair and tissue regeneration in all organisms. It is also a critical contributor to cancer metastasis, altered angiogenesis and neurite growth in disease. The molecular mechanisms regulating chemotaxis are currently being identified and key components may be pertinent therapeutic targets. Although these components...
