PTX3 expression varies across different cancers; for example, it is elevated in certain tumors such as hepatocellular carcinoma (Cabiati et al., 2022; Chen et al., 2024; Deng et al., 2020), ovarian cancer (Liu et al., 2024; Naylor et al., 2024; Tanılır Çağıran et al., 2024), and bladder cancer (Goodison et al., 2012; Vikerfors et al., 2024).
