Melatonin downregulates angiogenesis and lymphangiogenesis by regulating tumor-associated macrophages via NLRP3 inflammasomes in lung adenocarcinoma
Figure 4. Melatonin strongly inhibited angiogenesis and lymphangiogenesis via the NLRP3 inflammasomal axis. (A) The NLRP3, ASC, Caspase-1, IL-1β, and IL-18 transcript expressions in the melatonin-treated and control cells, as evidenced by RT-PCR. (B) The NLRP3, ASC, Caspase-1, IL-1β, and IL-18 protein expressions in the melatonin-treated and control cells, as evidenced by western blot assay. (C) The VEGF-A, VEGF-B, VEGF-C, CXCL8, and CXCL5 protein contents in the melatonin-treated and control cells, as evidenced by ELISA. (D, E) Branch point quantification. Typical phase-contrast images revealing tube formation. *p < 0.05, **p < 0.01. Data provided as mean ± SD (n = 3).
