Proteomic alterations in early stage cervical cancer

Project description:Cervical cancer is characterized by a well-defined pre-malignant phase, cervical intraepithelial neoplasia (CIN). Identification of high grade CIN lesions by population-based screening programs and their subsequent treatment has led to a significant reduction of the incidence and mortality of cervical cancer. Cytology-based testing of cervical smears is the most widely used cervical cancer screening method, but is not ideal, as the sensitivity for detection of CIN2 and higher (CIN2+) is only ~55%. Therefore, more sensitive and specific biomarkers for cervical cancer and its precancerous stages are needed.

Pre-invasive versus microinvasive carcinoma of the cervix

Project description:Comparative analysis of gene expression prodfiles of cervical biopsy from two (2) patients with pre-invasive neoplastic lesions (carcinonma in citu, or high-grade cervical intraepithelial neoplasia) and 2 patients with earliest stage of invasive cancer

Direct on-swab metabolic profiling of vaginal microbiome:host interactions during pregnancy and preterm birth

Project description:The pregnancy vaginal microbiome contributes to risk of preterm birth, the primary cause of death in children under 5 years of age. Here we describe direct on-swab metabolic profiling by Desorption Electrospray Ionization Mass Spectrometry (DESI-MS) for sample preparation-free characterisation of the cervicovaginal metabolome in two independent pregnancy cohorts (VMET, n = 160; 455 swabs; VMET II, n = 205; 573 swabs). By integrating metataxonomics and immune profiling data from matched samples, we show that specific metabolome signatures can be used to robustly predict simultaneously both the composition of the vaginal microbiome and host inflammatory status. In these patients, vaginal microbiota instability and innate immune activation, as predicted using DESI-MS, associated with preterm birth, including in women receiving cervical cerclage for preterm birth prevention. These findings highlight direct on-swab metabolic profiling by DESI-MS as an innovative approach for preterm birth risk stratification through rapid assessment of vaginal microbiota-host dynamics. Linked cross omic data sets:Meta-taxonomics data associated with this study are available in the European Nucleotide Archive (ENA): accession number <a href='https://www.ebi.ac.uk/ena/browser/view/PRJEB11895' rel='noopener noreferrer' target='_blank'>PRJEB11895</a>, <a href='https://www.ebi.ac.uk/ena/browser/view/PRJEB12577' rel='noopener noreferrer' target='_blank'>PRJEB12577</a> and <a href='https://www.ebi.ac.uk/ena/browser/view/PRJEB41427' rel='noopener noreferrer' target='_blank'>PRJEB41427</a>.

Genome-wide DNA methylation analysis of cervical scrapes samples

Project description:Genome-wide DNA methylation profiles in liquid based cytology (LBC) cervical scrapes samples was assessed using the Illumina Infinium Methylation850 BeadChip V1.0B4. The purpose of this study was to identify new candidate genes that are differentially methylated in squamous cell carcinoma compared to the DNA samples from cervical intraepithelial neoplasia grade (CIN) and normal cervical scrapes.

miRNA expression in LGCIN outcomes

Project description:The goal of this study was to investigate differential regulation of miRNA expression in the cervical tissue of women with low-grade cervical intraepithelial neoplasia (LGCIN, or low grade cervical dysplasia). We compared the miRNA expression profiles of women with LGCIN that progressed to high-grade CIN to the miRNA expression profiles of women with LGCIN that naturally resolved without medical intervention.
