PG - 144-50 LID - 10.1016/j.biopha.2011.11.021 [doi] AB - CD44 molecule plays critical role in distant malignant metastasis. It is expressed in standard form (CD44s) or variant form (CD44v). Tumor necrosis factor-alpha (TNF-alpha) is highly expressed in the cancer microenvironment. TNF-alpha was reported to modulate CD44 expression in several kinds of cancer. However, little is known about pathological role of TNF-alpha in breast cancer (BC) cells. In the current investigation, we investigated the effect of TNF-alpha on BC cells (MCF-7 and MDA-MB-231) viability, CD44 expression, and in vitro migration. We found that TNF-alpha down-regulated CD44s expression, up-regulated CD44v3 and CD44v6 expression through JNK pathway in MCF-7 cells. In MDA-MB-231 cells, TNF-alpha up-regulated CD44s, CD44v3 and CD44v6 expression via p38 pathway. These data indicate important role of CD44 molecule in BC pathology.
