Development of a living organoid biobank derived from colorectal cancer patients: Towards personalized medicine
2019
Abstract Background Organoids are 3D in vitroprimary culture of great interest for translational research representing an efficient and reproducible cancer model. The aim of this project is to generate a biobank of colorectal cancer (CRC) patients derived organoids (PDOs) that could be used to analyze molecular characteristics and to test different treatments as well as to study the underlying molecular causes of cancer and treatment resistance. Methods Primary or metastatic CRC tissues have been obtained from patients who underwent surgery. Tissue has been washed and incubated with antibiotics. After mechanical and enzymatic digestion, free cells have been seeded in Matrigel with proper me…
ZNF518B as a transcriptional factor involved in colorectal cancer progression through the epithelial to mesenchymal transition
2019
Abstract Background Colorectal cancer (CRC) represents a relevant public health problem. The identification of new markers involved in the mechanisms of invasiveness represents a priority in order to better understand cancer development and generate new therapeutic targets. Recently, our group demonstrated overexpression of ZNF518B gene, which encodes an unknown zinc finger transcription factor, in CRC. A transcriptome-wide gene expression profile revealed its implication in different biological processes related to the progression of CRC, especially in the epithelial to mesenchymal transition (EMT). Methods To study the biological processes regulated by ZNF518B, we performed a ClariomS Arr…
The role of tumor-associated macrophages in gastric cancer development and their potential as a therapeutic target.
2020
Gastric cancer (GC) represents the fifth cause of cancer-related death worldwide. Molecular biology has become a central area of research in GC and there are currently at least three major classifications available to elucidate the mechanisms that drive GC oncogenesis. Further, tumor microenvironment seems to play a crucial role, and tumor-associated macrophages (TAMs) are emerging as key players in GC development. TAMs are cells derived from circulating chemokine- receptor-type 2 (CCR2) inflammatory monocytes in blood and can be divided into two main types, M1 and M2 TAMs. M2 TAMs play an important role in tumor progression, promoting a pro-angiogenic and immunosuppressive signal in the tu…
