These mAbs were next tested on normal tissues from organs previously found to express FRA on the luminal surface (kidney, salivary gland, alveolar surface of the lung, etc.)and negative for FRA (ovary, liver, heart, etc.)as well as previously reported FRA-positive carcinomas (ovarian, NSCLC, renal, breast, etc.). The gene discussed is FOLR1; the disease is non-small cell lung carcinoma.
