They treated THP-1 cells or human monocytes with either exogenous LA or gastric cancer cell-derived conditioned media under normoxia, and found significantly increased expression of M2-related markers (IL-10, CD163, and ARG1) and faintly decreased expression of M1-related markers (IL-1, CCR7, and INOS). The gene discussed is ARG1; the disease is gastric cancer.
