Outline of Final Research Achievements

Lysophosphatidic acids(LPAs) have been implicated in the tumorigenesis of head and neck squamous cell carcinoma (HNSCC). We investigated the mRNA expression levels of LPA receptors(LPA1-6), LPA producing enzyme(Autotaxin;ATX) ,and LPA degrading enzyme(ACP6) in HNSCC samples. The expression levels of LPA1 in hypophalynageal carcinoma(HPC) was eight times higher than that of LPA4. Further more, HPC showed high expression level of ATX. Our data suggest that the difference of LPA1 and LPA4 expression may influences malignant beahviors of HNSCCs.
