The FBXW7 protein has been shown to regulate cellular growth and is a well-characterized tumor suppressor. This protein is a crucial component of the Skp1-Cullin1-F-box (SCF) complex, which is a ubiquitin ligase. This complex aids in the degradation of many oncoproteins, such as cyclin E, c-JUN, c-MYC, NOTCH, and MCL1, via the ubiquitin-proteasome system (UPS).
Gynecological cancers include ovarian, uterine/endometrial, cervical, vaginal, and vulvar cancers. These malignancies pose a huge worldwide health-socio-economic burden due to their high incidence and mortality among women, irrespective of age. Lack of screening, limited awareness of specific symptoms, late diagnosis, or even misdiagnosis, combined with limited treatment options for advanced gynecological cancers, are the main contributing factors leading to the high morbidity and mortality, thus stressing the need for further advances in the area of gynecological cancers. There is mounting evidence indicating that the aberrant expression of FBXW7 is involved in the development of gynecological cancers. This review provides an update on the role of FBXW7, not only as a potential biomarker, but also as a therapeutic target for novel oncologic treatments, particularly in the management of gynecological cancers.
