Cells of the nucleus pulposus (NP) in the intervertebral disc are derived directly from the embryonic notochord. In humans, a shift in NP cell population coincides with the beginning of age-related changes in the extracellular matrix that can lead to spinal disorders. To begin identifying the bases of these changes, the manner by which relevant(More)
The role of glycosylphosphatidylinositol (GPI)-anchored sperm proteins in reproduction has been investigated. SDS-polyacrylamide gels (PAGE) analysis of goat sperm (Capra indica) indicated that several GPI-anchored proteins were released by phosphatidylinositol-specific phospholipase-C (PI-PLC) treatment. The distribution of this category of(More)
AIM The mode of anchorage of N-acetyl beta-D-glucosaminidase (NAGA) on human ejaculated sperm was investigated. METHODS Sperm plasma membrane was prepared by discontinuous sucrose gradient centrifugation from human sperm. NAGA was solubilized from these membranes by two detergents: octyl-glycoside and triton X-100. In separate studies, the release of the(More)
INTRODUCTION Degeneration of the intervertebral disc (IVD) is characterized by marked degradation and restructuring of the annulus fibrosus (AF). Although several matrix metalloproteinases (MMPs) have been found to be more prevalent in degenerate discs, their coordination and function within the context of the disease process are still not well understood.(More)
