Researchers develop novel 3-D culture system for inflammatory breast cancer
Date:12/8/2012

lay between cancer cells and the microenvironment.

Moreover, exposure to the matrix caused all of the cancer cells to increase their expression of the protein epithelial cadherin (i.e., E-Cadherin), whose levels are often elevated in IBC tumors. These findings suggest that the microenvironment may promote the proliferation, growth and invasion of IBC tumors.

"Our system could be used to predict the in vivo behavior of cells and to study the signaling mechanisms that are responsible for tumor-microenvironment interactions in IBC cancer," Cukierman says. "We have some gene candidates that we believe are responsible for the degree of aggressiveness we observe in the 3D model, so we would like to manipulate these genetically using mutants or pharmacologically using inhibitors to block the proteins that we believe are responsible. If that reverses the aggressiveness, it could give us a good hint of what types of targets we could perhaps try to develop and bring to the clinic in the future."
