The expression of PAFR is elevated in several human tumor lineages [e.g., Kaposi's sarcoma cells 16, the endometrial cancer cell line HEC-1A 17, epidermoid carcinoma (A431 cells) 18, the stomach cancer cell line JR-St 19, and N1E-115 neuroblastoma cells 20]. The gene discussed is PTAFR; the disease is neoplasm.
