Abstract
|
|
|
Purpose: JAK kinases play important roles not only in normal cellular processes, but they are also important in tumor development. A recent study identified two somatic mutations of JAK1 in leukemia cells that were detected in exon 10 (p.T478S) and exon 13 (p.V623A). The aim of this study was to see whether the JAK1 mutations in these exons occur in non-small cell lung cancers (NSCLC).
Materials and Methods: We analyzed the exons 10 and 13 of JAK1 for detecting somatic mutations in NSCLC by performing polymerase chain reaction (PCR) and single-strand conformation polymorphism (SSCP) assay.
Results: The SSCP analysis revealed no evidence of somatic mutation in the DNA sequences of JAK1 exon 10 and exon 13 in the 47 NSCLCs.
Conclusion: The data presented here indicate that the JAK1 exons 10 and 13 may not be somatically mutated in human NSCLCs, and this suggests that the JAK1 mutation in exons 10 and 13 may not play an important role in the tumorigenesis of NSCLCs.
