Human leukocyte antigen-G (HLA-G) is a non-classical HLA-class Ib molecule with multiple immunoregulatory properties. Its main functions in physiological conditions are to abolish maternal immune cell activity against fetus and to establish immune tolerance at the maternal-fetal interface. Cervical tumor cells have been reported to express HLA-G which is one of the immunomodulatory molecules that is involved in every phase of cancer immunoediting. It has inhibitory functions against natural killer (NK) cells, T-lymphocytes, and antigen-presenting cells (APCs)...

PURPOSE: Human papillomavirus (HPV) DNA screening reduces cervical cancer incidence and mortality in low-resource settings. Self-collected vaginal samples tested with affordable HPV tests such as careHPV can increase the rate of screening in resource-constrained settings. We report the role of visual inspection with acetic acid (VIA) as a triage test for women testing positive with the careHPV test on self-collected vaginal samples. METHODS: As part of a multicountry demonstration study, 5,207 women 30 to 49 years of age were recruited from urban slums to undergo four cervical screening tests using the careHPV test on self-collected vaginal samples, provider-collected cervical samples, the Papanicolaou test, and VIA...

BACKGROUND: HIV-positive women are at substantial risk of HPV-associated cervical neoplasia caused by high-risk (HR) HPVs. Methylation of the HPV genome is associated with cervical intraepithelial neoplasia grade 3 (CIN3) in HIV-negative women, yet it is unknown whether this holds true for HIV-positive women. METHODS: We designed a case-control study within the WIHS cohort comparing HIV-positive CIN3 cases (N=72) to HIV-positive controls without detectable CIN2+...

Cervical cancer is one of the leading causes of cancer death in women globally, despite widespread use of cytology/Human Papillomavirus (HPV) screening. Here, we aimed to identify the potential role of miRNA as diagnostic biomarker in the detection of cervical pre-malignant lesions and cancer. In total, we recruited 582 patients with cervical diseases and 145 control individuals. The expression levels of six miRNAs (miR-20a, miR-92a, miR-141, miR-183*, miR-210 and miR-944) were found to be significantly up-regulated in cervical cancer and pre-malignant lesions as compared to normal cervical samples, indicating that they are oncogenic miRNAs...

OBJECTIVE: HPV16/18 genotyping and detection of hypermethylation of human cell genes involved in cervical oncogenesis have shown promising results in triage of high-risk HPV (hrHPV)-screen positive women on cervical smears. These tests can be performed on self-samples, which contain cervical and vaginal cells. We studied whether a self-sample represents the hrHPV type causing the worst cervical lesion and whether any differences in hypermethylation of FAM19A4/miR124-2 exist between CIN lesions caused by different hrHPV types...

BACKGROUND: The 2014 Bethesda System for Reporting Cervical Cytology classifies squamous intraepithelial lesions (SILs) of cervix in 2 main categories: Low-grade SIL (LSIL) and High-grade SIL (HSIL). In some clinical practices, "LSIL cannot rule out high grade lesion (LROH)" interpretive category is used in cases with LSIL and findings that may raise the possibility of HSIL. Our purpose is to assess follow-up histopathology and high-risk human papillomavirus (hrHPV) results in patients with LROH, in comparison with LSIL, atypical squamous cells, cannot rule out HSIL (ASC-H), and HSIL in our institution...

Overlapping genes across high-grade squamous intraepithelial lesions (CIN2 and 3) and cancer may serve as potential biomarkers for this progressive disease. Differentially expressed genes (DEGs) of dysplastic (CIN2 and CIN3) and cancer cells were identified by microarray data analysis. Gene interaction network was constructed using the 98 common DEGs among the dysplastic and cancer cells and analysed for the identification of common modules, hubs and significant motifs. Two significant modules and 10 hubs of the common gene interaction network, with 125 nodes and 201 edges were found...
