Abstract Objective: High-risk human papillomavirus (HR-HPV) is the main etiological factor for cervical cancer. Accumulating evidence has suggested that the active role of metabolites in the initiation and progression of cancers. This study was to explore the metabolic profiles of HR-HPV infection and their potential functions in cervical cancer.Methods: Non-targeted metabolomics approach was used to detect metabolic alterations in the plasma obtained from HPV-16 positive (HPV16 (+)), HPV-18 positive (HPV18 (+)) and HPV negative (CTL) individuals, followed by CCK8 experiment to detect the effect of different metabolites on the proliferation of Hela and GH354. A cell migration test then verified significant metabolites on the migration of Hela and GH354. Q RT-qPCR and western blot were used to detect malignant progression related mRNA and protein expression levels of cervical cancer.Results: HR-HPV groups shared 24 dysregulated metabolites (such as amino acids, ceramides, glycerophosphocholines). Further experiments showed ceramide species, including C8 inhibits cervical cancer cells proliferation and migration in vitro. In contrast, C12 significantly enhanced cervical cancer cells proliferation and migration in vitro. Protein and mRNA expressions indicated C8 and C12 were related to the malignant behavior of cervical cancer in vitro. The underlying mechanism demonstrated that C8 intervention inhibited proliferation and migration in cervical cancer cells via the MAPK/JNK signaling pathway, while C12 intervention promoted proliferation and migration in cervical cancer cells via the MAPK/ERK signaling pathway. These findings may contribute to the treatment of HR-HPV-induced cervical cancer by intervening in its initiation and progression.Conclusion: Our study shed some light on how metabolites influenced the relationship between HR-HPV oncogenic capability and metabolic phenotype change and identify species C8 and C12 as critical lipid metabolites that modulate cervical cancer cell’s function.

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.
