The Expression of Histone Acetyltransferase KAT6A in Non-small Cell Lung Cancer

Background/aim: KAT6A is considered a factor influencing carcinogenesis. Due to the fact that lung cancer is one of the leading causes of death, the aim of our study was to evaluate KAT6A expression in non-small cell lung cancer (NSCLC) tumors and the NSCLC cell line model.

Materials and methods: The expression of KAT6A was examined in NSCLC tumors by real-time PCR and immunohistochemistry. KAT6A expression was investigated in the NSCLC cell line model by real-time PCR, western blot, and immunofluorescence.

Results: KAT6A protein level was elevated in NSCLC tumors compared to non-malignant lung tissues (NMLT). The KAT6A mRNA expression in NSCLC, lung adenocarcinoma, and lung squamous cell carcinoma samples was differentiated. The results from the in vitro NSCLC model demonstrated elevated expression of KAT6A in lung cancer cell lines in comparison to normal lung fibroblasts.

Conclusion: The outcomes showed an increased KAT6A protein level in NSCLC compared to control samples, which suggests the oncogenic role of KAT6A in this type of cancer. Therefore, targeting KAT6A in NSCLC might be worth consideration.
