Project description:The Illumina Infinium 27k Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles across approximately 27,000 CpGs in smear cells from the uterine cervix (liquid based cytology samples), obtained from 48 women. All women tested positive for the human papilloma virus (HPV+). Of the 48 samples, 24 were cytologically normal while the other 24 exhibited morphological transformation (cervical intraepithelial neoplasia of grade 2 or higher - CIN2+).

Bisulphite converted DNA from the 48 samples were hybridised to the Illumina Infinium 27k Human Methylation Beadchip v1.2
Project description:The aim of this study is characterization of proteomic composition of the CVF for assessing the severity of HPV-associated intraepithelial neoplasias of the cervix among women of reproductive age.
Project description:Integration of human papillomavirus (HPV) DNA into the host genome is a critical aetiological event in the progression from normal cervix to intraepithelial neoplasm, and finally to invasive cervical cancer. In this study, we want to know how HPV DNA physical status relates to treatment outcome for cervical carcinomas.

In this study, we want to know how HPV DNA physical status relates to treatment outcome for cervical carcinomas. Cervical cancer samples were compared with normal sample. And also, we divided 39 cervical cancer patients into four groups according to HPV DNA physical status and investigated differentially expressed gene profiles in these groups using Agilent two-color experiment.
Project description:Genome wide DNA methylation profiling of normal and preinvasive cervical smear samples infected with the human papilloma virus (HPV) The Illumina Infinium 27k Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles across approximately 27,000 CpGs in liquid based cytology (LBC) cervical smear samples. Samples included 19 normal smears without HPV, 11 normal smears with HPV infection, and 18 smears with HPV and exhibiting dysplasia. email: a.teschendorff@ucl.ac.uk Keywords: DNA methylation
Project description:Squamocolumnar junction (SCJ) of the uterine cervix is a target of human papilloma virus (HPV) infection and thereby a putative cell-of-origin for uterine cervical cancer. However at present, in vitro models that accurately phenocopy its homeostasis is lacking. In this study, we aimed at establishing organoids of SCJ cells and identifying its characteristics. Samples were collected from the uterine cervix of 4 cases who underwent hysterectomy at our department, and processed to initiate organoid culture. Organoids were obtained from 3 samples among them, and they were analyzed both histologically and by transcriptome analysis.

Project description:Identification of copy number alterations of HPV-positive and HPV-negative vulvar squamous cell carcinomas (VSCC) and vulvar intraepithelial neoplasias (VIN), with special focus on VIN with and without VSCC, the latter group being defined as VIN with no VSCC development during >10 year follow-up.
