Abstract: OBJECTIVE:To use the transcriptome sequencing technology to investigate molecular mechanism of gallic acid (GA) against Burkitt lymphoma in vitro. METHODS:Inhibitory effect of GA on proliferation of human lymphoma Raji cells was assessed using the CCK-8 and PrestoBlue assays. Transcriptome sequencing technology was employed,combined with differential expression analysis,functional annotation,and pathway enrichment analysis,to decipher its mechanism of action. Key gene expression was validated by quantitative real-time PCR (RT-qPCR). RESULTS:Compared with the control group,both CCK-8 and PrestoBlue assays indicated that 50 and 100 μmol/L GA significantly inhibited the proliferation activity of Raji cells (P<0.05 or P<0.01). Transcriptomic analysis further revealed that GA exerted its anti-proliferation effects primarily by regulating the Fcγ receptor-mediated phagocytosis pathway. RT-qPCR results demonstrated that 100 μmol/L GA significantly suppressed the expression levels of key regulatory genes (VAV3IGHG2IGHV3-33) in this pathway (P<0.05 or P<0.01),which was consistent with the transcriptome sequencing results. CONCLUSION:GA not only demonstrated direct cytotoxic effects but also enhanced the recognition and phagocytosis of tumor cells through modulation of tumor cell surface receptors.
