High levels of malondialdehyde (MDA), pro-inflammatory cytokines (IL-6, TNF-α, and IL-1β), angiogenic factors (IL-8 and VEGF), monocyte chemoattractant protein-1 (MCP-1), and oxidized LDL (ox-LDL) were detected in the peritoneal fluid of endometriosis patients [2]. Here, TNF is linked to endometriosis.
