Abstract

Connective tissue growth factor (CTGF) is known to be a potent angiogenic factor. Here, we present the evidence that the hypoxic induction of angiogenesis by human breast cancer cells (MDA-231) can be ascribed at least in part to CTGF. Our results indicate that (i) CTGF is abundantly present in MDA-231 cells in vitro and in vivo, (ii) its secretion is up-regulated by hypoxia, and (iii) its gene expression is enhanced in MDA-231 cells cultured under hypoxic conditions. These data suggest CTGF may stimulate angiogenesis by paracrine mechanisms, thereby contributing to the invasion of breast cancer cells. This is the first evidence that human cancer cells differentially express CTGF protein and mRNA under the control of hypoxic conditions.
