Nettet27. mai 2008 · One is the cluster of the epidermal growth factor receptor (EGFR) and integrin in the cell growth process, and the other is the T cell receptor (TCR) complex in the immune system. EGFR has been reported to associate and cross-talk with an integrin in a signal transduction system ( 27 – 29 ). NettetWang et al illustrated that sulfide binds to integrin αVβ3 in HCC and induces clustering and phosphorylation of integrin αVβ3, triggering "outside-in" signaling. Bergamini et al [ 54 ] reported that laminin-5 (Ln-5) stimulates HCC growth via extracellular signal-regulated kinase (ERK) phosphorylation as a consequence of integrin β4 phosphorylation. djordje lj savic
