From: Study of the tumor microenvironment during breast cancer progression
The expression of T helper 2 subset markers. RNA was extracted from breast cancer and normal tissues. The expression level of GATA-3 (principle transcription factor of Th2 cells) and IL-13 was measured by qPCR. The amount of above genes was determined a in the breast cancer and normal tissues b in the different stages of tumor and control breast biopsies
