Gene expression profiles of human breast cancer cell lines MCF-7, T47D and MDA-MB-231 co-cultured with 3T3-L1 adipocytes.

ABSTRACT: Obesity is a known risk factor for breast cancer. To identify genes and underlying pathways in human breast cancer cells affected by interaction with mature adipocytes, two estrogen-receptor positive (ER+) breast cancer cell lines, MCF-7 and T47D, and the triple-negative (TN) breast cancer cell line MDA-MB-231 were cultivated in a co-culture system with or without differentiated murine 3T3-L1 adipocytes for the purpose of a microarray gene expression analysis. The use of in vitro differentiated 3T3-L1 adipocytes allowed comparable experimental conditions for each of the co-culture experiments with human breast cancer cell lines. For co-cultivation analyses of 3T3-L1 and breast cancer cells, we set up a two-dimensional transwell system, which enables intercellular communication through solu
