The MspI restriction-modification system, which recognizes the sequence 5'-CCGG-3', has been previously cloned and sequenced (1). We subcloned the methyltransferase gene (M.MspI) downstream of the ptac promoter in the multicopy... more
Yersinia enterocolitica and Yersinia pseudotuberculosis have been identified as causative organisms of reactive arthritis in humans. We evaluated a Western blot assay which uses Yersinia outer membrane proteins as antigens for the... more
Parathyroid hormone-related protein (PTHrP) is the major mediator of the humoral hypercalcemia of malignancy and of malignant osteolysis associated with skeletal metastases of common epithelial cancers. PTHrP secretion is regulated by the... more
Tacrolimus (FK506) is widely used as an immunosuppres-sor in clinical practice; nonetheless a great part of its mecha-nisms of action and the processes triggering side effects remain unknown.1) A wide spectrum of adverse effects including... more
Previous works revealed the presence of the nPKC enzyme p105 in hemocytes of M. galloprovincialis Lmk. Specific mussel antibodies were obtained from mouse and used in confocal microscopy and Western blotting. These techniques allowed the... more
In order to identify immunoreactive Bartonella henselae proteins, B. henselae antiserum from an experimentally infected cat was used to screen a B. henselae genomic DNA expression library. One immunoreactive phage clone contained a gene... more
Mycobacterium tuberculosis-specific antibodies possess immunomodulatory effects during tuberculosis infection. Prior sensitization to environmental mycobacteria is known to suppress immune responses against BCG and M. tuberculosis.... more
Xenopus liver contains a protein inhibitor of glucokinase that, in contrast to the mammalian regulatory protein of glucokinase, is insensitive to fructose 6-phosphate and fructose 1-phosphate [Vandercammen A. & Van Schaftingen, E. (1993)... more
RhoGTPases regulate actin-based signaling cascades and cellular contacts. In neurogenesis, their action modulates cell migration, neuritogenesis, and synaptogenesis. Murine P19 embryonal stem cells differentiate to neurons upon... more
Identification of components present in biological complexes requires their purification to near homogeneity. Methods of purification vary from protein to protein, making it impossible to design a general purification strategy valid for... more
Phosphorylation of the transcriptional coactivator YAP1 is a key event in defining Hippo signaling outputs. Previous studies demonstrated that phosphorylation of YAP1 at serine 127 (S127) sequesters YAP1 in the cytoplasm and consequently... more
Curcumin, a polyphenol derived from turmeric (Curcuma longa) possesses diverse pharmacological properties including antioxidant, anti-inflammatory and antiproliferative activities. Endometriosis is a gyneocological disorder characterized... more
Abnormal expression of matrix metalloproteinases (MMPs) has been implicated in the pathophysiology of neuroinflammatory processes that accompany most central nervous system disease. In particular, early upregulation of the gelatinases... more
