- 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.

- BACKGROUND
Expression of CXCR4 chemokine receptor, initially described to be involved in the homing of lymphocytes in inflammatory tissue, on breast cancer cell lines is associated with the development of lung metastases.
In the present study, we evaluated CXCR4 expression in patients with non-small cell lung cancer (NSCLC). METHODS: Tissue microarray blocks were constructed from 408 formalin-fixed, paraffin-embedded NSCLC samples and analyzed via immunohistochemical staining. RESULTS: We observed CXCR4 expression in 214 (66.3%) of the 323 tumors with cytoplasmic or nuclear staining patterns. These tumors were then divided into 109 negative, 166 weak-positive and 48 strong-positive expression groups. Strong expression of CXCR4 correlated with NSCLC recurrence (p=0.047) and distant metastasis (p=0.035). However, lymph node metastasis (p=0.683) and locoregional recurrence (p=0.856) were not associated with CXCR4 expression. Interestingly, the median overall survival times relative to CXCR4 expression were 71 months in the CXCR4-negative group, 43 months in the weakly positive CXCR4 group and 23 months in the strongly positive CXCR4 group.
Strongly positive CXCR4 staining was associated with significantly worse outcomes (p=0.005, log-rank test).
CONCLUSIONS
Expression of CXCR4 was associated with distant NSCLC metastases and shorter survival times.
