Carcinoma cells can acquire key malignant traits by reprogramming their differentiation state via an epithelial-to-mesenchymal transition (EMT). Cancer cells that undergo EMT become invasive and resist a wide range of therapies including most chemotherapy drugs and radiation. Such cells are also ab...

Microarrays were used to determine relative global gene expression changes upon introduction of EMT-inducing or control vectors. Experimentally immortalized HMLE breast epithelial cells were retrovirally transduced in culture with vectors encoding EMT-inducing genes or control vectors. There were t...

Microarrays were used to determine relative global gene expression changes in WT and BRCA1-mutation carrier breast epithelium as well as tumors created from WT and BRCA1-mutation carrier breast epithelial cells. Total RNA was isolated from freshly dissociated mammary epithelilal cells obtained from ...

Malignant carcinomas that recur following therapy are typically de-differentiated and multi-drug resistant (MDR). De-differentiated cancer cells acquire MDR by upregulating reactive oxygen species (ROS)-scavenging enzymes and drug efflux pumps, but how these genes are upregulated in response to de-d...
