Figure 5From: Activated Akt1 accelerates MMTV-c-ErbB2 mammary tumourigenesis in mice without activation of ErbB3MMTV-c-ErbB2 tumours demonstrate different cell cycle proteins than tumours from bitransgenic MMTV-myr-Akt1, MMTV-c-ErbB2 mice. Lysates from tumour (T) and normal mammary tissue (N) were used for immunoblot analysis using the following antibodies: (a) anti-phospho-Rb (Ser780); (b) anti-Rb; (c) anti-cyclin D1; (d) anti-p15; and (e) anti-p27.Back to article page
