We also studied the association of SATB1 expression with various molecules which have been previously identified as biological and prognostic markers in colorectal carcinoma, including Bcl-2 (anti-apoptotic protein), Cyclin D1 (proliferation marker), MMP-2 (invasion marker), NF-κB (anti-apoptotic factor and nuclear transcription factor), P53 (tumor suppression gene), APC (tumor suppression gene) and PCNA (proliferation marker). Here, APC is linked to colorectal carcinoma.
