For example, in the context of mantle cell lymphoma (MCL), signal transducer and activator of transcription 5B (STAT5B) suppresses ferroptosis by promoting the transcription of DDB1 and CUL4-associated factor 13 (DCAF13) that in turn ubiquitinates p53, thereby increasing SLC7A11 expression and resistance to ferroptosis in MCL [192]. Here, DDB1 is linked to mantle cell lymphoma.
