Characterizing the invasive tumor front of aggressive uterine adenocarcinoma and leiomyosarcoma
Ontology highlight
ABSTRACT: Invasive tumor front (the tumor-host interface) is vitally important in malignant cell progression and metastasis. Tumor cell interactions with resident and infiltrating host cells and with the surrounding extracellular matrix and secreted factors ultimately determine the fate of the tumor. In this study we focus on the invasive tumor front, making an in-depth characterization of reticular fiber scaffolding, infiltrating immune cells, gene expression and methylation profiles of classified aggressive primary uterine adenocarcinomas and leiomyosarcomas.
Project description:Invasive tumor front (ITF, the tumor-host interface) is vitally important in malignant cell progression and metastasis. Tumor cell interactions with resident and infiltrating host cells and with the surrounding extracellular matrix and secreted factors ultimately determine the fate of the tumor. Herein we focus on the invasive tumor front, making an in-depth characterization of reticular fiber scaffolding, infiltrating immune cells, gene expression and epigenetic profiles of classified aggressive primary uterine adenocarcinomas (uADC) and leiomyosarcomas (uLMS).
Project description:We have characterized the transcriptional program regulated by ETV5 at the invasive front of endometrial carcinomas, by comparing it with non-invasive areas of the same tumor samples. In total 12 samples; 6 superficial (non-invasive) tumor areas and the corresponding invasive tumor zones.

Project description:Cells located at the invasive front and in the tumor mass of mouse cervical squamous cell carcinomas were isolated by laser microdissection from hematoxylin-stained HPV/E2 sections. 7 months old HPV/E2 mice treated with oestrogen develop invasive cervical squamous cell carcinomas. This model recapitulates human invasive cervical neoplasias. We used microarrays to compare the transcriptome of cells located at the invasive front versus cells located in the tumor mass of mouse squamous cell carcinomas.
Project description:The experiment aimed to illuminate differences at the transcriptional level in whole tumor samples between the invasive front and central part of tumors. Samples were collected at the initial transurethral resection of the tumor.
