IntroductionPeroxiredoxin 3 (PRX3) is a member of PRX family with antioxidant functions by scavenging hydrogen peroxide. Since the development of cervical cancer is causally linked to high-risk human papillomavirus (HPV) that induces oxidative stress, we conducted the present study to investigate the response of PRX3 to high-risk HPV infection.Material and methodsThis study included fifty-six patients with invasive squamous cervical cancer and sixty control patients with hysteromyoma. Enzyme-linked immunosorbent assay was performed to detect cervical oxidative stress and serum PRX3. The expression of PRX3 and oncoprotein E6 of HPV16 or HPV18 was examined in cervical cancer tissues by immunohistochemistry. Western Blot was applied to detect the expression of PRX3 and E6 in cervical cancer cell lines including CaSki, HeLa, and C33A.ResultsPatients with cervical cancer showed higher serum PRX3 than control patients with hysteromyoma. Levels of oxidative markers in cervical cancer tissues were elevated as compared to normal cervical epithelia. PRX3 expression was upregulated in cervical cancer tissues and the upregulation was positively associated with the expression of E6 of HPV16 or HPV18. The association was confirmed in HPV-containing cervical cancer cell lines including CaSki and HeLa.ConclusionsOur results indicated a positive response of PRX3 to HPV-induced oxidative stress. Serum PRX3 might be a potential indicator of active amplification of high-risk HPV in cervical cancer cells.

Abstract Background Cervical cancer is the leading cause of cancer-related death in women worldwide. However, the mechanisms mediating the development and progression of cervical cancer are unclear. In this study, we aimed to elucidate the roles of microRNAs and a1-chimaerin (CHN1) protein in cervical cancer progression. Methods The expression of miR-205 and CHN1 protein was investigated by in situ hybridisation and immunohistochemistry. We predicted the target genes of miR-205 using software prediction and dual luciferase assays. The expression of mRNAs and proteins was tested by qRT-PCR and western blotting respectively. The ability of cell growth, migration and invasion was evaluated by CCK-8 and transwell. Cell apoptosis was analysed by flow cytometry analysis. Results We found that miR-205 and CHN1 were highly expressed in human cervical cancer tissue compared with paired normal cervical tissues. The CHN1 gene was shown to be targeted by miR-205 in HeLa cells. Interestingly, transfection with miR-205 mimic upregulated CHN1 mRNA and protein, while miR-205 inhibitor downregulated CHN1 in high-risk and human papilloma virus (HPV)-negative human cervical cancer cells in vitro,. These data suggested that miR-205 positively regulated the expression of CHN1. Furthermore, the miR-205 mimic promoted cell growth, apoptosis, migration, and invasion in high-risk and HPV-negative cervical cancer cells, while the miR-205 inhibitor blocked these biological processes. Knockdown of CHN1 obviously reduced the aggressive cellular behaviours induced by upregulation of miR-205, suggesting that miR-205 positively regulated CHN1 to mediate these cell behaviours during the development of cervical cancer. Furthermore, CHN1 was correlated with lymph node metastasis in clinical specimens. Conclusions Our findings showed that miR-205 positively regulated CHN1 to mediate cell growth, apoptosis, migration, and invasion during cervical cancer development, particularly for high-risk HPV-type cervical cancer. These findings suggested that dysregulation of miR-205 and subsequent abnormalities in CHN1 expression promoted the oncogenic potential of human cervical cancer.

In this study, we compared the effects of SKI-606 with Iressa, Src/Abl and EGF-R kinase inhibitors, respectively, on selected parameters in HeLa and SiHa cervical cancer cell lines, which express E6/E7 oncoproteins of high-risk HPV types 18 and 16, respectively. Our results show that SKI-606 and Iressa inhibit cell proliferation and provokeG0-G1cell cycle arrest and reduction of S andG2-M phase using 2 and 5 μMconcentrations of these inhibitors. In contrast, SKI-606 induces differentiation to an epithelial phenotype “mesenchymal-epithelial transition”; thus SKI-606 causes a dramatic decrease in cell motility and invasion abilities of HeLa and SiHa cancer cells, in comparison to untreated cells and Iressa-treated cells in which these parameters are only slightly affected. These changes are accompanied by a regulation of the expression patterns of E-cadherin and catenins. The molecular pathway analysis of Src/Abl inhibitor revealed that SKI-606 blocks the phosphorylation ofβ-catenin and consequently converts its role from a transcriptional regulator to a cell-cell adhesion molecule. Our findings indicate that SKI-606 inhibits signaling pathways involved in regulating tumor cell migration and invasion genes viaβ-catenin alteration, suggesting that Src inhibitor, in comparison to EGF-R, is a promising therapeutic agent for human cervical cancer.

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.
