Abstract

Breast cancer is a complex and multifactorial disease. The tumor microenvironment is an heterogenic environment with multiple interactions among tumor cells and other cell types which highly influence the tumor behavior. Several studies have revealed advantages of three-dimensional culture techniques (3D) over traditional two-dimensional monolayer cultures (2D). 3D cultures better mimic the tumor microenvironment found in vivo, as well as the interaction of cells with the extracellular matrix (ECM). Three-dimensional culture has produced different responses compared to those found in 2D cultures, such as increased resistance of tumor cells to various drugs, and increased selective sensitivity to tumor cells in relation to normal cells. The 3D cultures better mimic the tumor microenvironment found in vivo, as well as the interaction of cells with the extracellular matrix. Three-dimensional culture has produced different responses compared to those found in 2D cultures, such as increased resistance of tumor cells to various drugs, and increased selective sensitivity to tumor cells in relation to normal cells. The aim of this work is to apply new techniques for three-dimensional culture, learned in a world reference center (Bissell Lab - Lawrence Berkeley National Laboratory, California -USA) during the candidate's sandwich PhD, on screening of candidates to new antitumoral drugs in our laboratory. Previous results obtained during the stage using [10]-gingerol molecule have showed selectivity against malignant cells. The molecule was also able to revert the malignant phenotype and to induce apoptosis in this cell line. These new techniques will be used in our laboratory for the screening of candidate substances to new drugs with antitumor potential.
