We studied the gelatinolytic activity, caseinolytic activity and the level of tissue inhibitor of metalloproteinase-1 (TIMP-1) in the sclera from experimentally induced axially elongated eyes. The animal models were made by the injection of 250U alpha-chymotrypsin into the posterior chamber of young albino rabbits. Animals were killed with overdoses of intravenous pentobarbital and eyes were enucleated gently. Sclera from the equatorial area was then subjected to organ culture. The enzyme activity in the media was investigated by zymography using gelatin- or casein-containing gels together with an image analyzer system. TIMP-1 levels in each medium were measured by enzyme immunoassay (EIA). All samples showed three major bands of gelatinolytic activity at molecular weights of 87, 61, and 57 kDa. Gelatinolytic activity of 87 kDa increased 1.1 to 2.9 times compared with control sclera. All of the caseinolytic activity (87, 82, 52, and 50 kDa) was also elevated 1.8 to 6.6 times in samples from experimental eyes. TIMP-1 levels were mildly increased (up to 1.41 times) in the experimental eyes. These data suggest that degradation processes might be accelerated in the sclera from experimentally induced elongated eyes.
