Clinical significance and the correlation of expression between Let-7 and K-ras in non-small cell lung cancer.

To detect the expression levels of the lethal-7 (let-7) and K-ras genes in non-small cell lung cancer (NSCLC) and investigate their significance, the expression of let-7 and K-ras was determined in cancerous tissues and pericancerous normal tissues of 31 NSCLC patients using reverse transcription-polymerase chain reaction. Our results using 31 NSCLC patient samples showed that 67.74% had a low let-7 expression (P<0.
