13. Biochemical characterization and protein kinase C dependency of monokine-inducing activities of Toxoplasma gondii.
Previous reports have indicated that the early induction of interleukin-12 (IL-12), tumor necrosis factor alpha (TNF-alpha), IL-1beta, and IL-10 is crucial for the establishment and regulation of host cell-mediated immunity to the intracellular protozoan parasite Toxoplasma gondii. In this study, we demonstrate that a soluble tachyzoite extract (soluble tach

14. Methyl Jasmonate Induces Papain Inhibitor(s) in Tomato Leaves.
Leaves of 18- to 24-d-old tomato (Lycopersicon esculentum) plants exposed to gaseous methyl jasmonate (MJ) for 24 h at 30[deg]C in continuous light contained high levels of soluble protein that inhibited papain. Chromatographic analysis demonstrated that the active protein had a molecular mass of 80 to 90 kD. Induction of papain inhibitor was directly relate

15. Identification of a 50-kDa systemin-binding protein in tomato plasma membranes having Kex2p-like properties.
A protein of 50-kDa (SBP50) was identified in plasma membranes of tomato leaves which resembles proteases of the family of Kex2p-like prohormone convertases. To our knowledge, proteases of this class have not been reported in plants previously. A biotinylated derivative of systemin, the 18-aa polypeptide inducer of proteinase inhibitors in tomato and potato

16. Aluminum-Induced Genes (Induction by Toxic Metals, Low Calcium, and Wounding and Pattern of Expression in Root Tips).
We have investigated the response of four Al-induced genes (wali1, -3, -4, and -5) from wheat (Triticum aestivum L.) to other stresses. The relative transcript levels of wali1 (encoding a plant metallothionein-like protein), wali3 and wali5 (putative Bowman-Birk proteinase inhibitors), and wali4 (phenylalanine ammonialyase) increased in root tips of wheat af

17. Elastase and matrix metalloproteinase inhibitors induce regression, and tenascin-C antisense prevents progression, of vascular disease
Increased expression of the glycoprotein tenascin-C (TN) is associated with progression of clinical and experimental pulmonary hypertension. In cultured smooth muscle cells (SMCs) TN is induced by matrix metalloproteinases (MMPs) and amplifies the proliferative response to growth factors. Conversely, suppression of TN leads to SMC apoptosis. We now report th
