Du et al. (2022) constructed a prognostic model with excellent predictive performance based on FRGs. CA9/ULBP2 was also identified as a potential regulator of cervical carcinogenesis and progression. Qin et al. (2022) constructed a prognostic model with four iron death-associated genes and examined the immune microenvironment. Qi et al. (2021) developed a novel prognostic model with FRGs and validated the genes within the model. Xing et al. (2021) constructed a model with immune-associated genes and iron death genes related to OS in CESC patients, effectively predicting the outcome. Here, ULBP2 is linked to cervicitis.
