Project description:Evaluation of DNA extraction protocols from liquid-based cytology specimens for studying cervical microbiota
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.
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 normal cells from the uterine cervix (liquid based cytology samples), obtained from 152 women in a nested prospective case-control study within the ARTISTIC trial. Out of the 152 women, 75 developed a cervical intraepitelial neoplasia of grade 2 or higher (CIN2+) after 3 years of sample collection. The rest of women (77) remained disease free (CIN2-).
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:Human papillomavirus infection is the cause of essentially all cases of cervical premalignant lesions and cervical cancer. Primary screening using HPV DNA testing with cytology triage has been shown to be more sensitive and, importantly, more specific than conventional testing based on cytology among women more than 35 years of age. <br><br><br><br>The aim of the experiment was to evaluate a HPV genotyping microarray method using patient sample DNA. HPV genotyping is based on multiplex PCR (PGMY-t primers) followed by ligation step where two probes are ligated together if a matching template is present in the mixture. The ligated probes are then detected on microarray.
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 152 samples were hybridised to the Illumina Infinium 27k Human Methylation Beadchip v1.2
