Osteopontin Induction of Hyaluronan Synthase 2 Expression Promotes Breast Cancer Malignancy

Osteopontin (OPN) is a tumor-associated, secreted phosphoprotein that has been implicated in breast cancer progression and metastasis. Research concerning how OPN functions in tumor progression has led to the identification of a limited number of genes that contribute functionally to OPN-induced cellular behaviors. Recent microarray analysis, comparing 21NT breast cancer cells transfected to constitutively overexpress OPN with control cells, revealed hyaluronan synthase 2 (HAS2) to be a gene highly up-regulated in OPN-overexpressing cells. In this study, we further examined the relationship between OPN and HAS2. We show that 21NT cells of is with and and is tumor to cells and of 21NT cells OPN in a in and of in a in cellular and in this is the of the of OPN to and in breast cancer cells and further a relationship behaviors.
