For instance, a comprehensive analysis of PLK using databases like Oncomine, GEPIA, cBioPortal, and Kaplan-Meier plots revealed that PLK1 and PLK4 are potential targets for precision treatment in BC, while PLK2, PLK3, and PLK5 may serve as new prognostic biomarkers (Jiawei et al., 2022). The gene discussed is PLK3; the disease is breast cancer.
