RT-qPCR results showed that treatment with Lan C significantly upregulated the expression of several inflammation- and tumor-related genes, including FOS, TNFAIP3, NFKBIA, MMP3, CXCL8, CCL20, MYC, PTGS2, and IL-6, in PC-3 cells, while downregulating the expression of MAPK11, IL1B, MMP1, and MAPK13. The gene discussed is FOS; the disease is neoplasm.
