The findings reveal that in the group exhibiting heightened expression of CA125, a serum tumor marker associated with various cancers including ovarian, endometrial, and bladder cancers, there were elevated levels of M2 macrophage marker, CD163, as well as the regulatory T-cell (Treg) marker, FOXP3, compared to the group with lower CA125 expression. The gene discussed is CD163; the disease is neoplasm.
