Abstract:
Objective To investigate the expression of Cyclin F in clear cell renal cell carcinoma (ccRCC), its clinicopathological characteristics, and its effect on the biological behavior of renal cancer cell lines Methods RT-qPCR and Western blot were used to detect the mRNA and protein expression of Cyclin F in fresh ccRCC specimens. Immunohistochemistry assay was performed to detect the expression of Cyclin F protein in 80 paraffin samples. CCK-8 assay, scratch assay, and flow cytometry were conducted to determine the effects of Cyclin F overexpression on the proliferation, migration, and apoptosis of renal cancer cell lines. Results The expression of Cyclin F in cancer tissues was higher than that in adjacent tissues at the mRNA level (P<0.0285). The expression of Cyclin Fprotein in cancer tissues was lower than that in adjacent tissues (P<0.001). The analysis of clinicopathological parameters showed that the low expression of Cyclin F was correlated with WHO/ISUP grade, Ki67 index, and age (P=0.041, 0.047, 0.008,). In vitro experiments confirmed that overexpression of Cyclin F promoted the proliferation (P<0.001) and migratory ability (24 h P=0.003, 48 h P=0.0058) of the RCC 786-O cell line, while inhibiting apoptosis (P=0.0019). Conclusion The low expression of Cyclin F protein in ccRCC tissuesis associated with high ISUP grade, high Ki67 index, oldage, and prognosis of patients.
