Distribution of Met and its co-receptors in the human mammary gland remains poorly defined; however, strong expression of Met, ICAM-1, and CD44v6 has been associated with triple-negative breast cancers and correlated with poor prognosis (Charpin et al., 2009; Gastaldi et al., 2010; Ponzo and Park, 2010; Schroder et al., 2011). The gene discussed is AQP1; the disease is triple-negative breast carcinoma.
