SIX1 is upregulated in NSCLC tissues and correlates with LDH level in patients with NSCLC. (A) mRNA levels of SIX1 in NSCLC tissues (n=30) and normal lung tissues (n=30) were detected by reverse transcription-quantitative PCR. **P<0.01 vs. normal lung tissue. (B) The protein levels of SIX1 in NSCLC tissues and normal lung tissues were detected by western blot analysis. (C) The overall survival of NSCLC patients with low or high levels of SIX1 was analyzed by Kaplan-Meier analysis of data from The Cancer Genome Atlas database (P=0.00319). (D) The correlation between mRNA expression level of SIX1 and serum LDH level in patients with NSCLC was analyzed by Pearson's correlation analysis (R=0.6796, P=0.0014). NSCLC, non-small cell lung cancer; SIX1, sine oculis homeobox homolog 1; T, tumor; N, normal; LDH, lactate dehydrogenase.
