In mammals, extensive remodeling of uterine endometrial matrix occurs during reproductive cycle and blastocyst implantation. This is regulated by a variety of molecules such as hormones, growth factors, cytokines and proteases. In this article, we review the current state of knowledge available on
Soon after its discovery, the attempts to develop anti-AIDS therapeutics focused on the retroviral protease (PR)-an enzyme used by lentiviruses to process the precursor polypeptide into mature viral proteins. An urgent need for the three-dimensional structure of PR to guide rational drug design
Nelfinavir is a potent inhibitor of the HIV-1 protease, which shows good inhibitory activity against HIV-1 in vitro. Initial clinical trials have shown that it has excellent activity in vivo in HIV-infected patients. The combination of 750 mg nelfinavir three times daily with zidovudine and
Proteolysis is an early event of apoptosis which appears to be associated with activation of the endonuclease which is responsible for internucleosomal DNA cleavage. The present study was designed to reveal the possible role of proteolysis in other early events, such as chromatin condensation,
Several series of site-directed mutations in thermolysin-like proteases are presented that show remarkable nonadditivity in their effect on thermal stability. A simple model is proposed that relates this nonadditivity to the occurrence of independent partial unfolding processes that occur in
Folding studies on proteases by the conventional hydrogen exchange experiments are severely hampered because of interference from the autolytic reaction in the interpretation of the exchange data. We report here NMR identification of the hierarchy of early conformational transitions (folding
Early diagnosis and therapeutic intervention are needed to prevent the morbidity related to erosive arthropathies such as rheumatoid arthritis (RA), yet it is difficult to distinguish various forms of synovitis early in the disease course. The availability of synovial tissue biopsy techniques has
We have proposed that mature Schwann cells and an extracellular protease repress the sprouting response of axons. To test this hypothesis, we destroyed all cells by freezing a short span of the rat sciatic nerve or inhibited proteases with subperineurial injections of aprotinin, and a crush was made
The extracellular proteome, or secretome, of phytopathogenic fungi is presumed to be a key element of their infection strategy. Especially interesting constituents of this set are those proteins secreted at the beginning of the infection, during the germination of conidia on the plant surfaces or
We report 2 cases of maculopapular eruption and fever in patients infected with human immunodeficiency virus (HIV) on the 2nd day of first administration of ritonavir, a protease inhibitor. In the 1st patient, clinical improvement occurred despite continuation of therapy, and in the 2nd the
OBJECTIVE
To assess the balance between trypsin and protease inhibitors simultaneously in the systemic circulation and in the thoracic lymph and peritoneal exudate.
METHODS
Twenty patients with early severe acute pancreatitis were studied. Enzymatically active and immunoreactive trypsin in
OBJECTIVE
Recent findings indicate that intraintestinal pancreatic protease inhibition before superior mesentery artery occlusion (SMAO) attenuates inflammation and symptoms of shock. Herein we examine the effectiveness of delayed intestinal protease inhibition during reperfusion after
