Method for diagnosing non-small cell lung cancers by tRNA-dihydrouridine synthase activity of URLC8

摘要

The present invention features a method for determining t-RNA dihydrouridine-synthase activity of a polypeptide and screening for modulators of t-RNA dihydrouridine-synthase activity. The present invention further provides methods or pharmaceutical compositions for preventing and/or treating non-small cell lung cancer (NSCLC) using such modulators. Furthermore, the present invention provides methods for diagnosing non-small cell lung cancer (NSCLC) using the t-RNA dihydrouridine-synthase activity of IMS-E21 (URLC8) protein as an index. The present invention further provides methods for predicting and prognosing lung squamous-cell carcinoma (SCC).
