Abstract
To detect the serum protein expressions of histone deacetylase 1 (HDAC1) and DNA methyltransferase 1 (DNMT1) in patients with non-small-cell lung cancer and explore the correlation between their expressions and clinicopathological features. Enzyme-linked immunosorbent assay (ELISA) was used to measure the protein expressions of HDAC1 and DNMT1 in 136 lung cancer patients hospitalized at Department of Respiratory Diseases, First Affiliated Hospital,Zhengzhou University from September 2012 to June 2013 (cancer group). And 147 healthy physical examination subjects from Sixth People's Hospital of Zhengzhou were selected as controls and their clinicopathological features analyzed. The protein expressions of HDAC1 and DNMT1 in patients with lung cancer (145 ± 53, 50 ± 11) were higher than those in control group (78 ± 56, 27 ± 6). And there was statistical significance (t = 596.16, 152.64, both P = 0.000) . The protein expressions of HDAC1 and DNMT1 were correlated with gender, smoking history and age (among P < 0.05). There was a positive association between the protein expressions of HDAC1 and DNMT1 in non-small-cell lung cancer (r = 0.525, P = 0.000). Statistical significance existed between the protein expressions of HDAC1 and DNMT1 and histological types or different stages (all P < 0.01). The higher protein expressions of HDAC1 and DNMT1 may play an important role in the early process of lung cancer.
