Hs-AFP1, an antifungal plant defensin from seed of the plant Heuchera sanguinea, was radioactively labeled using t-butoxycarbonyl-[35S]L-methionine N-hydroxysuccinimidyl ester, resulting in a 35S-labeled peptide with unaltered antifungal activity. [35S]Hs-AFP1 was used to assess binding on living hyphae of the fungus Neurospora crassa. Binding of [35S]Hs-AFP1 was found to be competitive, revers...
Pto confers disease resistance to Pseudomonas syringae pv tomato carrying the cognate avrPto gene. Overexpression of Pto under the cauliflower mosaic virus 35S promoter activates spontaneous lesions and confers disease resistance in tomato (Lycopersicon esculentum) plants in the absence of avrPto. Here, we show that these AvrPto-independent defenses require a functional Prf gene. Several Pto-in...
This study examines thiamin transport in isolated rat hepatocytes and its relationship to thiamin phosphorylation. In an Na+ medium, [35S]thiamin, 3 microM, was accumulated rapidly by the cells, and a near study state intra-/extracellular distribution ratio of 3 was attained in 1 min. However, the uptake of radioactivity continued to increase with time owing principally to the accumulation of [...
A Fisher rat thyroid cell line was maintained in culture and the cells were labeled with [3H]glucosamine, [35S]sulfate, and [35S]cysteine to examine the synthesis of proteoglycans. 3H and 35S radioactivity from these precursors were incorporated into both chondroitin sulfate (CS) and heparan sulfate (HS) proteoglycans. CS proteoglycans were almost exclusively secreted into the medium while HS p...
Activation tagging using T-DNA vectors that contain multimerized transcriptional enhancers from the cauliflower mosaic virus (CaMV) 35S gene has been applied to Arabidopsis plants. New activation-tagging vectors that confer resistance to the antibiotic kanamycin or the herbicide glufosinate have been used to generate several tens of thousands of transformed plants. From these, over 30 dominant ...
Synthesis of sulphated proteoglycans by cell lines derived from explants of 7 rheumatoid and 9 normal specimens of synovial tissue, as well as by 7 lines of skin fibroblasts from non-rheumatoid patients, was examined. Cells of all 3 types were cultured as monolayers. They were then disaggregated and their capacity to synthesise proteoglycan estimated in cell suspensions by the incorporation of ...
Mononuclear phagocytes synthesize chondroitin sulfate proteoglycan (CSPG), which is constitutively secreted. Because mononuclear phagocytes are known to interact with blood platelets, the effect of platelets on the release of CSPG in cultured human monocytes was investigated. After 6 days in vitro, the monocytes were supplied with fresh medium with different additions and subsequently exposed t...
il-6 به عنوان محرک اصلی در تولید اکثر پروتئین های فاز حاد به شمار می آید. il-6 توسط مونوسیت ها، سلولهای اندوتلیال، فیبروبلاست ها و سلول های اندومتر تولید می شود. ژن کد کننده il-6 روی کروموزوم 7p21 واقع شده است. جایگاه های پلی مورفیک فراوانی در این منطقه از پروموتور وجود دارد. اندومتریوز یک بیماری خوش خیم است که بوسیله حضور بافت اندومتری فعال در خارج از فضای رحمی شناخته می شود. اندومتریوز یک بیم...
