Gene expression profiles of the human breast cancer cell line MDA-MB-231 co-cultured with adipose tissue from mice on chow or high-fat diet

ABSTRACT: Obesity is a known risk factor for breast cancer. To identify genes and underlying pathways in human triple-negative breast cancer cells affected by interaction with adipose tissue, MDA-MB-231 breast cancer cells were cultivated in a co-culture system with or without adipose tissue explants from mice for the purpose of a microarray gene expression analysis. Co-culture of MDA-MB-231 breast cancer cells was performed with adipose tissue explants obtained from C57BL/6J mice that were fed a high-fat diet (HFD, 58%Kcal from fat) or normal chow diet (NC; 11%Kcal from fat) ad libitum for 16 weeks. For co-cultivation analyses of breast cancer cells and adipose tissue explants, we set up a two-dimensional transwell system, which enables intercellular communication through soluble factors secreted into the medium but inhibits intermixture of the different cell types. Following 72 hours of co-culture with or without adipose tissue, total RNA was isolated from the breast cancer cells and subjected to microarray gene expression analyses.
