Increased activity and expression of phospholipase D2 in human colorectal cancer.
Phospholipase D (PLD) has been reported as relevant to some types of human cancer, but its role in human colorectal cancer still remains to be elucidated. Thus, this study was conducted to determine the activity and the expression of PLD2 in human colorectal cancer. A significant elevation of PLD2 activity and higher expression of PLD2 protein were detected in human colorectal cancer in comparison with corresponding normal mucosa. The tendency of higher expression of PLD2 mRNA was also observed. The ratio of PLD2 activity in cancer to that in corresponding normal mucosa was greater in colorectal cancer with nodal involvement and deeper tumor invasion. Our results indicate that PLD2 has a possible implication in carcinogenesis and progression and would be a new therapeutic target and a potential tumor marker for colorectal cancer.[1]References
