FASN and breast cancer: Therefore, we aimed to analyze the differentially expressed RBPs (DERBPs), including AHNAK, MAP1B (microtubule-associated protein 1B), LAMA2 (laminin subunit alpha-2), P4HB (prolyl 4-hydroxylase subunit beta), FASN (fatty acid synthase), and GSDMB (gasdermin B) in BC and explore their prognostic values.
