The molecular processes and proteomic markers leading to tumor progression (TP) in cervical cancer (CC) are either unknown or only partially understood. TP affects metabolic and regulatory mechanisms that can be identified as proteomic changes. To identify which proteins are differentially expressed and to understand the mechanisms of cancer progression, we analyzed the dynamics of the tumor proteome in CC cell lines. This analysis revealed two proteins that are up-regulated during TP, GSTM3 and GSTP1. These proteins are involved in cell maintenance, cell survival and the cellular stress response via the NF-κB and MAP kinase pathways during TP...

Metastatic nodal involvement is a critical prognostic factor in uterine cervical cancer (UCC). To improve current methods of detecting UCC metastases in lymph nodes (LNs), we used quantitative PCR (qPCR) to assess mRNA expression of potential metastatic biomarkers. We found that expression of HPV16-E6, cytokeratin19 (CK19), and mucin1 (MUC1) is consistently upregulated in tumors and metastatic tissues, supporting a role for these genes in UCC progression. These putative biomarkers were able to predict the presence of histologically positive metastatic LNs with respective sensitivities and specificities of 82% and 99% (CK19), 76% and 95% (HPV16-E6), and 76% and 78% (MUC1)...

Variations in systemic inflammatory response biomarker levels have been associated with adverse clinical outcome in various malignancies. In this study, we aimed to evaluate the predictive and prognostic role of the pretreatment neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) in cervical cancer. We retrospectively investigated 616 patients who underwent initial radical hysterectomy with pelvic lymphadenectomy for cervical cancer between July 2012 and December 2014 in China. Their clinical and histopathological markers and complete blood counts were obtained and analyzed...

miRNA-489 was shown to be a suppressor factor in many cancers, however, evidence on the effects and mechanism of miRNA-489 in progression of cervical cancer is limited. So we aimed to determine the function of miRNA-489 in cervical cancer proliferation and apoptosis in our present study. Interestingly, we found that miRNA-489 was significantly down-regulated in cervical cancer tissues. miRNA-489 overexpression inhibited the cell proliferation and improved the cell apoptosis of cervical cancer cells. Further, miRNA-489 over-expression suppressed the activation of PI3K and AKT, and stimulated P53 proteins expression...

Human papillomavirus (HPV) E2 and L1 proteins are expressed in cervical cells during the lytic stage of infection. Overexpression of p16INK4A is a biomarker of HPV-associated cervical neoplasia. This study investigated antibodies to HPV16 E2, HPV16 L1, and p16INK4A in sera from women with no squamous intraepithelial lesion (No-SIL) of the cervix, low-grade SIL, high-grade SIL, and cervical squamous cell carcinoma (SCC). HPV DNA was detected by polymerase chain reaction. Anti-E2, -L1, and -p16INK4A antibodies in sera were determined by western blot...

A growing body of studies has demonstrated that long non-coding RNA (lncRNA) are regarded as the primary section of the ceRNA network. This is thought to be the case owing to its regulation of protein-coding gene expression by functioning as miRNA sponges. However, functional roles and regulatory mechanisms of lncRNA-mediated ceRNA in cervical squamous cell carcinoma (CESC), as well as their use for potential prediction of CESC prognosis, remains unknown. The aberrant expression profiles of mRNA, lncRNA, and miRNA of 306 cervical squamous cancer tissues and three adjacent cervical tissues were obtained from the TCGA database...

Growing evidence has shown that a large number of miRNAs are abnormally expressed in cervical cancer (CC) tissues and play irreplaceable roles in tumorigenesis, progression, and metastasis. This study aimed to identify new biomarkers and pivotal genes associated with CC prognosis through comprehensive bioinformatics analysis. At first, the data of gene expression microarray (GSE30656) was downloaded from GEO database and differential miRNAs were obtained. Additionally, 4 miRNAs associated with the survival time of patients with CC were screened through TCGA differential data analysis, Kaplan-Meier, and Landmark analysis...

microRNAs (miRNAs) play important roles in regulation of gene expression during cervical carcinogenesis. We investigated expression profiles of miRNAs in cervical cancer and its precursor lesions by utilizing cervical mucus. Cervical mucus was collected from 230 patients with a normal cervix, cervical intraepithelial neoplasia (CIN), squamous cell carcinoma (SCC), or adenocarcinoma (AD). The levels of miRNA in the mucus were quantified by miRNA array and real-time reverse-transcriptase polymerase chain reaction (RT-PCR)...

The long-term chronic inflammation of cervical intraepithelial neoplasia (CIN) induces the initiation and progression of cervical cancer. Long non-coding RNAs (LncRNAs) are being identified to be involved into inflammation and carcinogenesis and could function as cancer biomarkers in clinical. However, the significance of inflammation-related LncRNA (e.g. LncRNA-IL7R) in cervical cancer is limited. We here investigated the clinical role of inflammation-related LncRNA-IL7R (Lnc-IL7R) in healthy cervical tissue (n=15), CIN 1/2/3 (n=35), cervical cancer (n=70), and clarified its function via knockdown in vitro and in vivo The results showed that the expression of Lnc-IL7R was increased from normal tissues to neoplastic lesions and cervical cancer...

Background: The ability to distinguish which hrHPV infections predispose to significant disease is ever more pressing as a result of the increasing move to hrHPV testing for primary cervical screening. A risk-stratifier or "triage" of infection should ideally be objective and suitable for automation given the scale of screening. Results: CCL2, CCL3, CCL4, CXCL1, CXCL8 and CXCL12 emerged as the strongest, candidate biomarkers to detect underlying disease [cervical intraepithelial neoplasia grade 2 or worse (CIN2+)]...

Infection of high-risk human papillomaviruses (HPVs) is a prerequisite for the development of cervical carcinoma. HPV infections are also implicated in the development of other types of carcinomas. Chronic or persistent infection of HPV is essential but HPV alone is inadequate, additional endogenous or exogenous cues are needed along with HPV to induce cervical carcinogenesis. The strategies that high-risk HPVs have developed in differentiating epithelial cells to reach a DNA-synthesis competent state leading to tumorigenic transformation are basically due to overexpression of the E6 and E7 oncoproteins and the activation of diverse cellular regulatory or signaling pathways that are targeted by them...

Of the numerous aspects involved in the diagnosis, treatment, and follow-up of cervical uterine precursor lesions, epidemiology, virology, cytology, human papillomavirus (HPV) testing, and diagnostic algorithms for equivocal and HPV-positive findings are important for pathologists. Cytology will continue to be used as a preventive medical check-up in young women, while HPV-based screening is suggested for older women. HPV screening has yielded a significant reduction in cancer precursors and invasive cervical carcinoma in numerous studies...

Cervical cancer incidence, globally, is second only to malignant breast cancer. The main causative factor is thought to be human papillomavirus (HPV) infection as a result of many sexual partners. Despite radiotherapy, chemotherapy and surgical treatment, the survival rate of patients with advanced disease is low. Metastasis is one of the stages of cancerogenesis in which tumour cells acquire the ability to migrate and create tumour secondary foci. Tumour biomarkers, proteins produced by neoplastic cells, quantified in body fluids or in tissues, play a key role in treatment monitoring and in determining the prognosis for further years of life...

In this meta-analysis, we analyzed case-control studies that assessed the prognostic potential of miRNAs in cervical cancer. We comprehensively searched EMBASE and PubMed databases and enrolled seven studies with 445 cervical cancer cases. A fixed effects model was used to calculate pooled hazard ratios (HRs) and associated 95% confidence intervals (95% CIs) from the overall survival (OS) data. Our analysis showed that poor OS in cervical cancer was associated with low miR-125 expression (HR = 1.61, 95% CI: 1...

There has been much progress in ovarian cancer screening and prevention in recent years. Improved tools that combine genetic and epidemiologic factors to predict an individual's ovarian cancer risk are set to become available for tailoring preventive and screening approaches. The increasing evidence on tubal origins of a proportion of ovarian cancer has paved the way to use of opportunistic bilateral salpingectomy at tubal ligation and hysterectomy in the general population. Clinical trials are in progress to estimate the long-term effects on endocrine function...
