As an interacting partner of CD147, integrin β1 interacts with CD147 to regulate integrin-dependent signaling and focal adhesion kinase (FAK) activation, leading to ignition of the downstream signaling Rac/Ras/Raf/ERK and phosphoinositide 3-kinases (PI3K)/Akt pathways and an increase in the metastatic potential of hepatocellular carcinoma [109]. The gene discussed is BSG; the disease is hepatocellular carcinoma.
