Dendritic cell-specific intercellular adhesion molecule-3-grabbing nonintegrin-related protein (DC-SIGNR) is a type II transmembrane protein that has been reported to bind to various pathogens and participate in immunoregulation and tumorigenesis. However, further research is required to investigate whether the level of DC-SIGNR and cervical cancer are associated. The present study aimed to explore the clinical diagnostic significance of DC-SIGNR in cervical cancer. Immunohistochemical staining of DC-SIGNR was performed in samples from 25 patients with early stage cervical cancer, 14 patients with cervical intraepithelial neoplasia (CIN) and cervical polyp samples from 15 individuals...

BACKGROUND: Using primary human papillomavirus (HPV) testing for cervical screening increases detection of high-grade cervical intraepithelial neoplastic lesions and invasive cancer (cervical intraepithelial neoplasia grade 2+ [CIN2+]) compared to cytology, but no evaluation has been conducted in a population previously offered HPV vaccination. We aimed to assess colposcopy referral and CIN2+ detection rates for HPV-screened versus cytology-screened women in Australia's HPV-vaccinated population (by 2014, resident women ≤33 years had been age-eligible for HPV vaccination, with 3-dose uptake across age cohorts being about 50%-77%)...

Risk stratification of human papillomavirus (HPV)-positive women is needed to avoid excessive colposcopy and overtreatment in cervical cancer screening. We aimed to evaluate the predictive value of type-specific HPV in detecting cervical cancer and precancers in a Chinese population-based cohort and provide evidence of HPV genotyping to triage HPV-positive women. We typed all Hybrid Capture 2-positive cytological samples of 1,742 women in Shanxi Province Cervical Cancer Screening Study cohort. Cumulative risks of cervical intraepithelial neoplasia grade 2 or worse (CIN2+) among HPV positive women and cumulative detection rates of CIN2+ among general women by type-specific HPV were estimated during the course of ten-year follow-up...

BACKGROUND/AIM: Bcl-2-like protein 11 (BIM) is a pro-apoptotic member of the Bcl-2 protein family. BIM elicits cell death by binding to pro-survival Bcl-2 proteins. Even though the association of BIM expression with cell death has been investigated, its clinical survival significance in cervical cancer has not. In the current study, the prognostic significance of BIM in cervical cancer was investigated. PATIENTS AND METHODS: The study included normal cervical tissues (n=254), cervical intraepithelial neoplasia (CIN) tissues (n=275), and invasive cervical cancer (n=164)...

BACKGROUND/AIM: Nicotinamide phosphoribosyl transferase (Nampt) catalyses the rate-limiting step of the mammalian nicotinamide adenine dinucleotide (NAD) salvage pathway. Nampt is highly expressed in several epithelial and mesenchymal neoplasms, where is promotes cell-cycle progression ans chemotherapy resistance. To our knowledge, alterations in Nampt expression have not been examined in cervical intraepithelial neoplasia (CIN) or squamous cell carcinoma (SCC). MATERIALS AND METHODS: We performed immunohistochemical analysis for Nampt using tissue microarrays on 14 samples of benign cervical squamous epithelium and 15 CIN I, 15 CIN II, and 13 samples of CIN III...
