ABSTRACT
Objective To investigate the role of ATP citrate lyase(ACLY)in the development of hepatocellular carcinoma(HCC)and the impact of this enzyme on the immune microenvironment of HCC.Methods We utilized the University of Alabama at Birmingham Cancer Data Analysis Portal and the Gene Expression Profiling Interactive Analysis to identify the changes in ACLY expression and prognosis across different tumor types from The Cancer Genome Atlas.With HCC as the disease model,we analyzed the ACLY expression in HCC samples from the gene expression database.Furthermore,we collected the clinical specimens from HCC patients to verify the mRNA and protein levels of ACLY.In addition,we conducted transcriptome sequencing after knocking down the expression of ACLY to analyze the differentially expressed genes and investigated the impact of ACLY expression interference on cell proliferation and other functions.Finally,we explored the correlations of ACLY with immune cells and immune infiltration in the tumor microenvironment,new antigens,and immune checkpoint genes.Results ACLY expression was significantly up-regulated in solid tumors including HCC(all P<0.05),and high ACLY expression was associated with overall survival rate in HCC(P=0.005).Furthermore,high ACLY expression affected the presence of immune cells(e.g.,tumor-associated fibroblasts)and the expression of genes involved in lipid metabolism(all P<0.05).Conclusions ACLY is closely related to the occurrence and development of HCC and lipid metabolism abnormalities.Moreover,it has a specific impact on the immune microenvironment of HCC.
