Abstract
Cervical cancer is one of the recognized malignant tumors of female reproductive system. At present, the research and development of biomarkers has attracted increasing attention, and the wide application of clinical cervical cancer screening strategies has significantly reduced its morbidity and mortality. A member of the F-box protein family, FBXO22, is involved in cell cycle, DNA damage repair and many other processes. Dysregulation of FBXO22 plays an important role in the occurrence and development of various tumors, including ovarian cancer, liver cancer and lung cancer. Nevertheless, the effect of FBXO22 in cervical cancer needs further investigation. We found that FBXO22 inhibited cervical cancer cell proliferation, migration and invasion. The results of proteomics studies suggested FBXO22 appears to target the Cyclin G Associated Kinase (GAK) for degradation. The combined results of analysis of cultured cells with altered abundance of FBXO22 by depletion or over-expression in the presence or absence of proteasomal inhibitor, comparison of protein decay rate, as well as cellular ubiquitination, support a hypothesis that FBXO22 mediates the ubiquitin-dependent degradation of GAK. Taken together, our data suggest that FBXO22 has a protective role in cervical cancer.

[PMID: 35806128 PMCID: PMC9266862 DOI: 10.3390/ijms23137126] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2022] [Revised: 06/20/2022] [Accepted: 06/24/2022] [Indexed: 02/01/2023] Open
Abstract
Globally in 2020, an estimated ~600,000 women were diagnosed with and 340,000 women died from cervical cancer. Compared to 2012, the number of cases increased by 7.5% and the number of deaths increased by 17%. MiRNAs are involved in multiple processes in the pathogenesis of cervical cancer. Dysregulation of miRNAs in the pre-stage of cervical cancer is the focus of this review. Here we summarize the dysregulated miRNAs in clinical samples from cervical pre-cancer patients and relate them to the early transformation process owing to human papillomavirus (HPV) infection in the cervical cells. When HPV infects the normal cervical cells, the DNA damage response is initiated with the involvement of HPV’s E1 and E2 proteins. Later, cell proliferation and cell death are affected by the E6 and E7 proteins. We find that the expressions of miRNAs in cervical pre-cancerous tissue revealed by different studies seldom agreed with each other. The discrepancy in sample types, samples’ HPV status, expression measurement, and methods for analysis contributed to the non-aligned results across studies. However, several miRNAs (miR-34a, miR-9, miR-21, miR-145, and miR-375) were found to be dysregulated across multiple studies. In addition, there are hints that the DNA damage response and cell growth response induced by HPV during the early transformation of the cervical cells are related to these miRNAs. Currently, no review articles analyse the relationship between the dysregulated miRNAs in cervical pre-cancerous tissue and their possible roles in the early processes involving HPV’s protein encoded by the early genes and DNA damage response during normal cell transformation. Our review provides insight on spotting miRNAs involved in the early pathogenic processes and pointing out their potential as biomarker targets of cervical pre-cancer.
