BACKGROUND
One of the histone acetyltransferases (HATs) family of proteins, human MOF (hMOF, MYST1), is involved in histone H4 acetylation, particularly at lysine 16 (H4K16Ac), an epigenetic mark of active genes. Dysregulation of the epigenetic mark influences cellular biology and possibly leads to oncogenesis. We examined the involvement of hMOF and H4K16Ac in primary non-small cell lung cancer (NSCLC).
METHODS
Reverse transcription polymerase chain reaction using fresh-frozen lung cancer tissues and lung cancer cell lines and immunohistochemistry for hMOF and H4K16Ac via tissue microarray of 551 formalin-fixed paraffin-embedded NSCLC tissue blocks were conducted.
RESULTS
hMOF mRNA was frequently overexpressed in lung cancer tissues, compared with normal lung tissues (10/20, 50%). NSCLC tissues were positive for hMOF in 37.6% (184/489) and H4K16Ac in 24.7% (122/493) of cases. hMOF protein expression was tightly correlated with the H4K16Ac level in tumors (p<0.001). Knockdown of hMOF mRNA with siRNA led to a significant inhibition of growth in the Calu-6 cell line.
CONCLUSIONS
hMOF was frequently expressed in NSCLC and was correlated with H4K16Ac. To our knowledge, this is the first study that has focused on the expression status of HATs and hMOF in NSCLC. Our results clearly suggest a potential oncogenic role of the gene and support its utility as a potential therapeutic target.

Abstract PDF

BACKGROUND
MicroRNA (miRNA) is a class of noncoding protein RNA as a promising biomarker for various diseases. In this study, the expression of let-7b, miR-30c, and miR-200c was studied in breast cancer tissues to evaluate the potential relationship with known clinicopathological parameters.
METHODS
Quantitative real-time polymerase chain reaction was performed to determine the expression level of three miRNAs in 37 pairs of noncancerous normal and cancer tissues and an additional 38 cancer tissues from patients with invasive ductal carcinoma.
RESULTS
miR-200c expression was higher in cancer tissues compared to noncancerous normal tissues, and its ratio was correlated with patient age at surgery, type of surgery, and Ki-67 expression. The expression level of let-7b in cancer tissues was inversely correlated with lymph node metastasis, histological grade, and Ki-67 expression but positively correlated with estrogen and progesterone receptor expression. miR-200c expression level was positively correlated with Her-2 expression. The miR-30c expression level in breast cancer was not correlated with any parameters.
CONCLUSIONS
miR-200c and let-7b could be used as biomarkers in patients with breast cancer, but its pathological mechanism should be determined.
