A large number of studies suggest that CPT1B takes part in promoting the malignant progression of cancer cells in a variety of cancers, such as breast cancer, gastric cancer, prostate cancer, pancreatic ductal adenocarcinoma, etc., and is closely related to the malignant phenotype of tumor cells and ferroptosis [90,91,92,93,94,95]. The gene discussed is CPT1B; the disease is breast carcinoma.
