Pre-invasive versus microinvasive carcinoma of the cervix

Changes in gene expression and mechanisms underlying activation of tumor invasion and spread at the early steps of squamous cervical carcinoma progression.

Project description:The development of an HPV-associated cervical cancer usually takes a long time (years, decades) and comprises stepwise change of intraepithelial (preclinical) neoplastic forms, but after invasive carcinoma is established it demonstrates extremely aggressive behavior and heterogenic molecular profile. Women with pre-invasive neoplastic lesions or early-stage invasive cervical cancer who underwent treatment in the Republican Oncological Dispensary were enrolled in our study (all were HPV-positive). Tissue samples were excised during surgery before any other treatment. Comparative transcriptomic analysis of invasive cancers (with an emphasis to the earliest stages) versus non-invasive precursor lesions was performed by means of RNA sequencing.

Transcription profiling of human pre-invasive and invasive cervical squamous cell carcinomas and normal cervical epithelia

Project description:10 normal squamous cervical epitheilia samples, 7 high grade squamous intraepithelial lesions, and 21 invasive squamous cell carcinomas of the cervix samples were obtained using laser capture miicrodissection. Two rounds of T7-based linear RNA amplification using the Arcturus RiboAmp kit were performed for each sample, and assayed using Affymetrix HG_U133A arrays. Experiment Overall Design: 10 normal squamous cervical epitheilia samples, 7 high grade squamous intraepithelial lesions, and 21 invasive squamous cell carcinomas of the cervix, each from different patients, were each assayed on single HG_U133A arrays. Three additional test samples were also assayed. Experiment Overall Design: The log-transformed probe-set values and the results of the statistical analysis for each probe-set, and the associated README file, are included as Supplementary files.

Epigenome analysis of smear cells from the uterine cervix consisting of 24 normals and 24 cervical intraepithelial neoplasias (all HPV+)

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+).

microRNA profile in the cervical mucus of the cervical neoplasia

Project description:Cervical mucus was collected from 86 patients with a normal cervix, cervical intraepithelial neoplasia (CIN), squamous cell carcinoma (SCC), or adenocarcinoma (AD). 76 candidates of miRNAs were selected according to criteria such as absolute value of the signal intensity included more than 20 and the ratio of the SCC/normal or AD/normal included more than four.

Array comparative genomic hybridization analysis of flat epithelial atypia (DIN1a) and lobular intraepithelial neoplasia

Project description:Low grade flat ductal intraepithelial neoplasia (DIN1a, flat epithelial atypia) is one of the earliest morphologically recognizable neoplastic lesions of the breast. Frequently, it occurs in association with lobular intraepithelial neoplasia (LIN). The aim of this study was to elucidate chromosomal aberrations in these early neoplastic breast lesions using array comparative genomic hybridization (CGH) analysis. Laser capture microdissection of 12 archival formalin-fixed, paraffin-embedded specimens harbouring both foci of DIN1a as well as LIN was performed. All analyzed cases of DIN1a and LIN showed chromosomal gains and losses. The aberration encountered most often was loss on 16q in 7 DIN1a (70%) and 10 LIN (91%) cases. Regarding changes in chromosome 1, four DIN1a (40%) and 7 LIN (64%) cases showed a gain on 1q. The results of our study show concurrent chromosomal aberrations of 1q gains and 16q losses in several cases with coexisting LIN and low grade flat DIN. These aberrations are known to be common in low grade invasive ductal carcinomas as well as more advanced (conventional) types of low grade DIN (low grade ductal carcinoma in-situ). Our results raise the possibility of similar molecular-genetic pathways in most of the cases with coexisting LIN and low grade flat DIN.

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.

Differential analysis of gene expression profiles in peripheral blood cells of patients with cervical lesions

Project description:Using RNA-sequencing analysis of peripheral blood cells from 11 cervical cancer patients, 21 cervical intraepithelial neoplasia patients and 19 healthy controls, we identified a group of differentially expressed genes. A real time quantitative reverse transcription polymerase chain reaction (qRT-PCR) was applied to the validation of candidate markers in the blood of 115 patients and 46 healthy controls. The results suggest that a six-gene predictor set (GZMB, NDUFA1, GPR84, NUAK1, AGAP1 and CIR1) can be used as candidate genes for the detection of cervical cancer.
