Abstract:
Objective To explore the association between arachidonic acid(AA)metabolism and cervical cancer(CC),to provide new ideas for metabolic therapies for CC.Methods The activity and migration ability of CC cells after AA intervention were detected by CCK-8 assay and cell scratch assay,respectively.Bioinformatics analysis was performed using GEPIA 2 and GSCA databases to study the correlation between key enzymes of AA metabolism(COX2,ALOX15)and the progression,prognosis,pathway activation,and tumor immunity of CC.The mRNA expression of inflammatory factors interleukin-6(IL-6),monocyte chemoattractant protein-1(MCP-1),tumor necrosis factor-α(TNF-α),interferon-γ(IFN-γ),cyclooxygenase 2(COX2),and arachidonic acid lipoxygenase 15(ALOX15)were detected by real-time fluorescence quantitative polymerase chain reaction(RT-qPCR).Results A A at 5μmol/ml significantly promoted the growth of CC cells(t=7.672,P=0.0166)and increased the relative cell migration rate by 30％at the same concentration(t=6.672,P=0.0026).And the expression levels of inflammatory factors also showed significant differences(P＜0.05).Further bioinformatics analysis revealed that the expression levels of key enzymes of AA metabolism,COX2 and ALOX15,were significantly up-regulated in CC(P＜0.05),which also different in different stages and increased the risk of poor prognosis in patients.Among them,COX2 may accelerate the progression of CC by decreasing the level of tyrosine kinase metabolism and exacerbating DNA damage,and ALOX15 may form a tumor inflammatory environment by increasing the degree of infiltration of resting CD8+T cells and B lymphocytes.Conclusion AA metabolism promotes the proliferation and migration of CC cells and induces changes in the tumor inflam-matory microenvironment,in which its metabolic key enzymes,COX2 and ALOX15,may play an important role.
