MMP1 and colorectal carcinoma: Interestingly, we detected a significant decline in the transcript levels of senescence‐associated genes and pro‐inflammatory cytokines: C‐C motif chemokine ligand 2 (CCL2), matrix metallopeptidase 1 (MMP1), interleukin‐6 (IL‐6), and interferon‐β (IFN‐β) in human lung epithelial IMR‐90 (Figure 2a, Table S6) or human colorectal carcinoma epithelial Caco2 (Figure 2b, Table S6) cells exposed to VA.
