To investigate the role of AhRR and PPP1R3C in ovarian cancer, we analyzed the data from The Cancer Genome Atlas (TCGA) and GSE datasets using Kaplan–Meier Plotter web server (https://kmplot.com/analysis/index.php?p=service&cancer=ovar (accessed on 5 May 2023)), selecting the serous histotype. The gene discussed is PPP1R3C; the disease is ovarian cancer.
