The overexpression of EGFR and the typeⅠcAMPdependent protein kinase(PKAⅠ) has been found in most cancer tissue and tumour cells.The blockade of EGFR activation by using anti-EGFR monoclonal antibodies(MAbs) and inhibition of PKAⅠ expression by specific pharmacological agents such as the selective cAMP analogue 8-Cl-cAMP has been proposed as a potential anticancer therapy.We have shown that an interaction between EGFR and PKAⅠ occurs through direct binding of the RⅠsubunit to the Grb2 adaptor protein.We have demonstrated that the functional interaction between the EGFR and the PKAⅠ pathways could have potential therapeutic implications.In fact,the combined interference with both EGFR and PKAⅠ with specific pharmacological agents,has a cooperative antiproliferative effect on human cancer cell lines in vitro and in vivo.Studies on the antitumor activity of this combination are under human clinical trial evaluation.

This study was aimed to explore the methodology regarding culture, proliferation and purification of adipose-derived stromal cells (ADSCs), and to study their biological characteristics. ADSCs were obtained using type I collagenase digestion method. Cell growth was observed, and cell viability were detected under different digestion period by MTT. The ADSCs were then identified and induced. The results showed that adherent cells digested by type I collagenase for 60 min had a strong proliferation capability. After the induction of different inducers these adherent cells could differentiate into nerve cells and fat cells. The best digestion period was proved to be of 60 minutes in the experiment. The results indicate that stem cells with multilineage differentiation ability could be separated from adipose tissue, namely ADSCs.
