Abstract

BACKGROUND & OBJECTIVE:

Nasopharyngeal carcinoma (NPC) is one of the most common cancers in South China and Southeast Asia. The etiological factor is believed to be the interaction between genetic susceptibility, EBV infection and environmental factors, involved in the multi-step process of carcinogenesis and development of NPC. However, the molecular pathology of NPC is unclear yet. Kruppel-like factor 6(KLF6) is a ubiquitously expressed nuclear transcription factor, which is deleted and/or mutated with high frequency in a subset of prostate cancer. This study was designed to investigate KLF6 mutation in NPC tumors and NPC cell lines.

METHODS:

Genomic DNAs from 19 NPC tumor biospies and 3 NPC cell lines were used in mutation detection of KLF6 coding region and splice sites by PCR-sequencing. 100 chromosomes from 50 random healthy individuals were used as control.

RESULTS:

In 3 of 19 NPC tissues, 3 different mutations (Glu75Val, Ser136Arg, Arg243 Lys) in KLF6 gene were found by PCR-sequencing. None of the 3 mutations were detected in the 50 random healthy individuals.

CONCLUSION:

KLF6 gene may be involved in carcinogenesis of sporadic NPC.
