However, LCK (but not SRC) expression in 21 cancer cell lines of the upper aerodigestive tract correlated with the general metastatic potential, i.e. metastasis to all five investigated organs (r = 0.467, p = 0.0328), especially with metastasis to the bone (r = 0.474, p = 0.0297) and a trend is seen for lung metastasis (r = 0.366, p = 0.1024) as well. The gene discussed is SRC; the disease is cancer.
