Alteration of tumor suppressors changes the endometrial tumor spectrum

Like most cancers, early‐stage endometrial cancer has a more favorable prognosis, while high‐grade, including endometrioid and nonendometrioid, has the worst prognosis.

Zusammenfassung: | The most common gynecological cancer in Europe and the United States is endometrial. Like most cancers, early‐stage endometrial cancer has a more favorable prognosis, while high‐grade, including endometrioid and nonendometrioid, has the worst prognosis. In endometrioid human tumors, the tumor suppressor genes PTEN and p53 (Trp53) are frequently altered or lost, as identified in datasets from The Cancer Genome Atlas. These suppressors' somatic mutations or loss of gene expression can lead to neoplastic development, tumor progression, and therapeutic resistance. In addition, somatic missense mutations are prevalent in another tumor suppressor, the F‐box and WD repeats containing 7 (FBXW7). FBXW7 is part of the SCF‐βTrCP ubiquitin complex that signals protein destruction. Specifically, FBXW7 is responsible for binding and facilitating the destabilization of proteins involved in proliferation and migration. Losing the function of multiple tumor suppressors could activate pathways involved in neoplastic progression, malignancy, therapeutic resistance, and formation of different tumor subtypes. The study by Brown
et al
in this issue of
EMBO Mol Med
(Brown
et al
, 2023) provides insight into the complexity of tumor suppressor mutations in malignant endometrial cancer. |
