Adipose cells and breast cancer -- a dangerous combination
Apart from its direct effect on health (such as cardiovascular diseases and diabetes), obesity is increasingly suspected of playing a role in the prognosis of breast cancer and, in particular, its propensity to spread. However, no direct cause and effect relationship had been demonstrated until now. This breakthrough has finally been made through the collaborative work of two teams of researchers from Inserm, CNRS and the Université Paul Sabatier (France). Their research has made it possible to highlight, both in vitro and in vivo, the presence of adipose cells (known as adipocytes) near breast tumors. These adipocytes have specific biological characteristics. When associated with tumors, they are capable of modifying the characteristics of cancerous cells, making them more aggressive. The results of this work are published in Cancer Research of 1st April 2011.
