Abstract

Abtract Forkhead box A1 (FOXA1) is a pioneer transcription factor that is essential for the normal development of several endoderm-derived organs, including the prostate gland 1,2. FOXA1 is frequently mutated in hormone-receptor-driven prostate, breast, bladder and salivary-gland tumours 3-8. However, it is unclear how FOXA1 alterations affect the development of cancer, and FOXA1 has previously been ascribed both tumour-suppressive 9-11 and oncogenic 12-14 roles. Here we assemble an aggregate cohort of 1,546 prostate cancers and show that FOXA1 alterations fall into three structural classes that diverge in clinical incidence and genetic co-alteration profiles, with a collective prevalence of 35%. Class-1 activating mutations originate in early prostate cancer without alterations in ETS or SPOP, selectively recur within the wing-2 region of the DNA-binding forkhead domain, enable enhanced chromatin mobility and binding frequency, and strongly transactivate a luminal androgen-receptor program of prostate oncogenesis. By contrast, class-2 activating mutations are acquired in metastatic prostate cancers, truncate the C-terminal domain of FOXA1, enable dominant chromatin binding by increasing DNA affinity and-through TLE3 inactivation-promote metastasis driven by the WNT pathway. Finally, class-3 genomic rearrangements are enriched in metastatic prostate cancers, consist of duplications and translocations within the FOXA1 locus, and structurally reposition a conserved regulatory element-herein denoted FOXA1 mastermind (FOXMIND)-to drive overexpression of FOXA1 or other oncogenes. Our study reaffirms the central role of FOXA1 in mediating oncogenesis driven by the androgen receptor, and provides mechanistic insights into how the classes of FOXA1 alteration promote the initiation and/or metastatic progression of prostate cancer. These results have direct implications for understanding the pathobiology of other hormone-receptor-driven cancers and rationalize the co-targeting of FOXA1 activity in therapeutic strategies.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
