(author), Griffioen, G. (author), Lamers, C.B.H.W. (author), Verspaget, H.W. (author), TNO Kwaliteit van Leven (author)Recently, complexes of matrix metalloproteinase matrix metalloproteinase-9 (MMP-9) with lipocalin-2 (neutrophil gelatinase-associated lipocalin) were found in the urine obtained from breast cancer patients, while these were completely absent in that obtained from healthy controls. In vitro data suggested a possible role for lipocalin-2 in the...article 2007

(author), van Krieken, J.H.J.M. (author), Lamers, C.B.H.W. (author), Verspaget, H.W. (author)In a pioneer study, we showed 10 years ago that enhanced tissue levels of the matrix metalloproteinases (MMPs) MMP-2 and MMP-9 in gastric cancers, as determined by zymography, were related with worse overall survival of the patients. To corroborate these observations, we now assessed MMP-2 and MMP-9 with new techniques in an expanded group of...article 2006

(author)Despite the advances in pre-, peri- andpost-operative medical care of colorectal carcinoma patients, the prognosis has improved only marginally over recent decades. Thus, additional prognostic indicators would be of great clinical value to select patients for adjuvant therapy. In previous studies we found that colorectal carcinomas have a marked...article 1997

(author), van Krieken, J.H.J.M. (author), Lamers, C.B.H.W. (author), Verspaget, H.W. (author)Proteinases are involved in tumour invasion and metastasis. Several matrix metalloproteinases (MMPs) have been shown to be increased in various human carcinomas. We assessed the levels of MMP-2 (gelatinase A) and MMP-9 (gelatinase B) in 50 gastric carcinomas and corresponding mucosa using quantitative gelatin zymography. Both MMP levels were...article 1996

(author), Instituut voor Verouderings- en Vaatziekten Onderzoek TNO (author)Human colorectal carcinogenesis has been shown previously to be associated with impressive changes in the tissue levels of plasminogen activators and their inhibitors, exemplified by an increase in the urokinase-type plasminogen activator (u-PA) and the inhibitors PAI-1 and PAI-2, and a decrease in tissue-type plasminogen activator (t-PA). In...article 1994

(author), Lamers, C.B.H.W. (author)In resection tissue samples of colorectal carcinomas, the concentration of urokinase-type plasminogen activator (u-Pa) was found to be significantly higher than in the normal parent mucosal tissue, while there was less tissue-type plasminogen activator (t-PA). u-PA and t-PA were also determined in endoscopic biopsies of colonic and gastric...article 1989

(author), Gezondheidsorganisatie TNO Gaubius instituut TNO (author)Plasminoceli activator (PA) activity, in particular urokinase (u-PA), has been shown to be markedly increased in adenocarcinomas of the colon. Adenomatous polyps were found to be intermediate in their PA activity to normal mucosa and adenocarcinomas. In the present study we evaluated the PA profile in relation to malignancy parameters of the...article 1988
