Background: High-risk human papillomavirus (HR-HPV) persistent infection is the main cause of cervical cancer and its precancerous lesions. A previous study showed that HPV16 and HPV58 infections were the most common infection types in the local region. Some studies also declared that HPV58 E7 variants increased the risk of cervical cancer among Asian populations. Objective: This study aimed to determine whether the HPV58 E7 T20I (C632T) variant promotes the malignant behavior of cervical cancer cells and the underlying mechanism of the HR-HPV E7 oncoprotein involved in the development of cervical cancer. Methods: CCK-8 and clone formation assays were used to detect cell proliferation ability. Transwell assays and cell wound healing assays were used to evaluate cell migration ability. Targeted knockdown of E2F1 expression using specific siRNA, RT-qPCR and Western blot were performed to assess gene expression changes. A chromatin immunoprecipitation assay was used to verify that E2F1 interacted with the TOP2A promoter region. Results: HPV58 E7 and HPV58 E7M oncoproteins increased the proliferation and migration ability of cervical cancer cells. However, the HPV58 E7 T20I variant did not promote malignant behaviors compared with wild-type HPV58 E7. HPV E7 and E7M oncoproteins increased the expression of TOP2A, BIRC5 and E2F1, and knockdown of HPV E7 decreased their expression. Low E2F1 expression reduced the expression of TOP2A and BIRC5 and inhibited the proliferation and migration ability of cervical cancer cells. E2F1 interacted with the TOP2A gene promoter region to promote its transcriptional expression. Conclusions: The HPV58 E7 T20I variant did not promote malignant behaviors compared with wild-type HPV58 E7. The HR-HPV E7 oncoprotein enhanced the proliferation and migration of cervical cancer cells, which was considered to be due to the HPV E7 oncoprotein increasing the expression of BIRC5 and TOP2A by upregulating the transcription factor E2F1.

ObjectiveThe aim of this study was to examine the relationship between miR-375 expression and the proliferation, apoptosis, and migration of cervical cancer cells. To further explore the potential target gene of miR-375, insulin-like growth factor 1 receptor (IGF-1R) was detected in miR-375 overexpressed and inhibited cervical cancer cells, which clarified the potential mechanism of miR-375 in the growth and development of cervical cancer.MethodsIn a cervical cancer cell line (Caski), miR-375 overexpression and knockdown were achieved by transfection with a synthetic miR-375 mimic or miR-375–targeting inhibitor oligonucleotides, respectively, using siRNA-Mate transfection reagents. Real-time Polymerase Chain Reaction was performed to detect the expression level of miR-375. The functional effects of miR-375 on cell proliferation, migration, and apoptosis were evaluated using a Cell Counting Kit (CCK-8) and through scratch wound tests and apoptosis assays, respectively. Western blotting was performed to detect the expression level of the IGF-1R protein.ResultTransfection with the miR-375 mimic significantly upregulated the expression of miR-375 by approximately 7.76-fold (P< 0.05), reduced cell proliferation and migration (P< 0.05), increased apoptosis (P< 0.05), and decreased the expression of the IGF-1R protein by 24.73% (P< 0.05) compared with the negative control. In contrast, transfection of the miR-375 inhibitor decreased the expression of miR-375 by 14.39% (P< 0.05), significantly increased cell proliferation and migration (P< 0.05), significantly reduced the cell apoptosis (P< 0.05), and upregulated the expression of the IGF-1R protein by 2.29-fold (P< 0.05). The cells transfected with the negative control showed no significant changes compared with the blank control for each parameter (P> 0.05).ConclusionsmiR-375 plays an important role in the tumorigenesis and development of cervical cancer. IGF-1R might represent a target gene of miR-375 in cervical cancer.
