Background
Lung cancer is one of the most common cancers in the word. However, the underlying mechanism remains largely unknown. ACOT11 encodes enzymes hydrolyzing the fatty acyl-CoA esters into free fatty acids and CoA. Besides from its role in fatty acid metabolism, the other aspects regarding its function in the progression of lung cancer have not been revealed.
Conclusions
The results revealed that ACOT11 regulates proliferation, migration and invasion of lung cancer carcinoma via multiple signaling pathways, indicating its potential value in molecular therapy.
Methods
We first explored the clinical profile of ACOT11 in tumor samples. Next, we combined gene knockdown in vitro and in vivo and microarray gene profiling analysis to decipher the unknown regulatory role of ACOT11 in lung cancer carcinoma. Furthermore, we explored the potential molecular mechanisms of ACOT11 with immunoprecipitation.
Results
We found high expression of ACOT11 in tumor samples. High expression of ACOT11 showed significantly poor prognosis in lung squamous carcinoma (LUSC) patients. Knocking down of ACOT11 inhibited the cell proliferation, migration as well as invasion in vitro and in vivo. It also promoted the cell apoptosis and cell cycle arrest via multiple signaling pathways. Additionally, ACOT11 could bind with CSE1L, which was proved to be an oncogene in lung cancer and speculated to be a potential target of ACOT11. Conclusions: The results revealed that ACOT11 regulates proliferation, migration and invasion of lung cancer carcinoma via multiple signaling pathways, indicating its potential value in molecular therapy.
