Zeraati 2015 10 01 There are increasing data on novel tumor markers such as gelatinase A, which play a key role in tissue invasion and metastasis. Since prostate cancer is one of the common malignancies, we designed a simple and applicable Indi¬rect Hemagglutination (IHA) test for determination of total gelatinase A in se¬rum samples. In this study, we have analyzed the circulating form of gelatinase A (MMP-2) in patients suffering from either benign prostate hyperplasia (n= 54) or prostate cancer (n= 26) and normal individuals as control (n= 26). The gelatinolytic activity was determined by zymography followed by densitomet-ric analysis. PSA was quantified by using a standard ELISA technique. Corre¬lation of densitometric analysis of gelatinase A activity and IHA titer was sig¬nificant at 0.01 level (p< 0.01, r = 0.916). Correlation of PSA and IHA titer was significant at 0.01 level (p< 0.01, r = 0.746). Border line IHA titer in patients with prostate cancer was 512 ± 1 tube titer, in benign prostate hyper¬plasia patients was 128 ± 1 tube titer, and the titer in normal individuals was 8 ± 1 tube titer. These results demonstrate that IHA compared to zymography may be a better and simpler procedure in monitoring and screening patients with prostate cancer. https://ijaai.tums.ac.ir/index.php/ijaai/article/view/50 https://ijaai.tums.ac.ir/index.php/ijaai/article/download/50/50
