Is the Marburg I polymorphism of factor VII activating protease associated with low proteolytic and low pro-coagulant activity?
Most likely TFPI cleavage by WT-FSAP occurs in vivo and contributes to an elevated level of endogenous FVIIa. This may explain why MI-FSAP is not a clear indicator for deep vein thrombosis in population studies. The loss of the pro-fibrinolytic protective function of FSAP in carriers of the MI-SNP may account for the association of the MI-SNP with atherosclerosis and thromboembolic complications.
This study points out that CIS is a marker of genetic instability of the urothelium mucosa. The CIS surrounding morphologically normal urothelium showed a high frequency of abnormal DNA content, with high percentage of clear aneuploid cells (high 5cER), p53 mutated protein expression, and a proliferative status underlying a field carcinogenesis. These alterations in normal mucosa were not found when CIS was not present.
