Another important marker of tumorigenesis is focal adhesion kinase (FAK), a 125-kDa tyrosine kinase that is overexpressed at the mRNA and protein levels in a variety of human tumors," scientists writing in the journal Molecular Carcinogenesis report. "FAK is a critical regulator of adhesion, motility, metastasis, and survival signaling. We have characterized the FAK promoter and demonstrated that p53 can inhibit the FAK promoter activity in vitro.
