Project description:Microarray expression profiling of cervical exfoliated cells (10k genes) We used whole genome microarrays (25,353 unique genes) to compare the transcription profiles from seven samples of normal exfoliated cells and one cervical tissue.
Project description:Epigenetic alterations are essential in the development of cancers, while epigenome-wide exploration in cervical cancer has been limited. In this epigenome-wide association study (EWAS) we explore differential DNA methylation signatures associated with CIN (cervical intraepithelial neoplasia) grade 3 and cervical cancer, to better understand potential drivers and biomarkers of cervical carcinogenesis. 247 women were recruited between 2014-2020 (N=119 benign, N=74 CIN3/CGIN (cervical glandular intraepithelial neoplasia) and N=54 cancer). Methylation signatures were obtained from exfoliated cervical cells and sequenced using the Illumina 850k array. Logistic regression and conditional analyses were used to test for independent associations between Cytosine-phosphate-Guanine (CpG) sites and case-control status, with adjustment for batch, chip, age, and human papillomavirus (HPV) status. 409 CpG sites were strongly associated with CIN3/cancer (P-value <5x10-8). Following conditional analysis, two CpG sites located in PAX1 (cg16767801) and NREP-AS1 genes (cg23642047) were independently associated with case status; yielding an area under the curve (AUC) of 0.92 (AUC=0.97 for invasive disease). In a validation dataset (CIN3 only) PAX1/NREP-AS1 yielded a combined AUC of 0.77. Methylation markers offer promise for use in cervical screening particularly as triage tests and self-sampling. We have identified a novel combined methylation marker that offers a high accuracy for detection of CIN3 or worse.
Project description:Mesenchymal stromal stem cells from human bone marrow (BMSCs), adipose tissuse (ADSCs) were purchased from ATCC. Human exfoliated deciduous dental pulps were cultured in vitro and purified to get stem cells from human exfoliated deciduous teeth (SHED). Markers of MSCs were checked before scRNA seq.

Project description:To investigate the different gens expression and RNA methylation degree in the cervical immortalized cervical cells and cervical cancer cells，
Project description:To explore the circRNA expression profiles during the development and progression of cervical cancer, we performed RNA sequencing analysis with ribosomal RNA-depleted in HPV negative normal cervical epithelium, HPV16 positive normal cervical epithelium, HPV16 positive high-grade squamous intraepithelial lesion (HSIL), and HPV16 positive cervical squamous cell carcinoma tissues,6 cases in each group.Totally 66868 circRNAs were identified (Back-spliced junctions reads≥1)
