سابقه و هدف: جنگل های زاگرس به عنوان یکی از بوم سازگان جنگلی مهم ایران پوشش گیاهی (درختان، درختچه ها گونه علفی) متنوعی برخوردار می باشد. شناسایی آگاهی دقیق نقش شناختی آنها در این سازگان تواند حفاظت منابع طبیعی توسعه پایدار کمک شایانی نماید. بهمنظور مطالعه تنوع گونهای گیاهان چوبی ذخیره کربن خاک رابطه با عوامل فیزیوگرافیک (جهت، شیب ارتفاع سطح دریا)، رویشگاه کیکم (var. cinerascens Acer...
A persistent infection in Madin Darby Canine Kidney (MDCK) cells by an influenza B virus (B/Tecumseh/63/80) has been established and characterized. Virus recovered from the persistent state titrated lower in relation to the parental wild-type (wt) that initiated the infection as measured by hemagglutination and egg and tissue culture infectious dose, suggesting that the virus is a less cytopath...
Differential targeting of myelin proteins to multiple, biochemically and functionally distinct Schwann cell plasma membrane domains is essential for myelin formation. In this study, we investigated whether the myelin protein P0 contains targeting signals using Madin-Darby canine kidney (MDCK) cells. By confocal microscopy, P0 was localized to MDCK cell basolateral membranes. C-terminal deletion...
Epithelial differentiation involves the generation of luminal surfaces and of a noncentrosomal microtubule (MT) network aligned along the polarity axis. Columnar epithelia (e.g., kidney, intestine, and Madin-Darby canine kidney [MDCK] cells) generate apical lumina and orient MT vertically, whereas liver epithelial cells (hepatocytes and WIFB9 cells) generate lumina at cell-cell contact sites (b...
In different epithelial cell types, integral membrane proteins appear to follow different sorting pathways to the apical surface. In hepatocytes, several apical proteins were shown to be transported there indirectly via the basolateral membrane, whereas in MDCK cells a direct sorting pathway from the trans-Golgi-network to the apical membrane has been demonstrated. However, different proteins h...
Caveolin-1 has been implicated in apical transport of glycosylphosphatidylinositol (GPI)-anchored proteins and influenza virus hemagglutinin (HA). Here we have studied the role of caveolin-1 in apical membrane transport by generating caveolin-1-deficient Madin-Darby canine kidney (MDCK) cells using retrovirus-mediated RNA interference. The caveolin-1 knockdown (cav1-KD) MDCK cells were devoid o...
Disruption of cellular plasma membranes is a common event in many animal tissues, and the membranes are usually rapidly resealed. Moreover, repeated membrane disruptions within a single cell reseal faster than the initial wound in a protein kinase A (PKA)- and protein kinase C (PKC)-dependent manner. In addition to wounded cells, recent studies have demonstrated that wounding of Madin-Darby can...
PCR was used to amplify and sequence the complete HA1 region of the haemagglutinin (HA)-encoding genes of 10 clinical isolates of influenza virus of the H1N1 or H3N2 subtypes. These sequences were compared to those obtained from viruses isolated from the same specimens after passage in eggs and MDCK cells. Amino acid substitutions in the egg-derived HA sequences were found in nine out of the 10...
Diisopropylfiuorophosphate {OFP), a general serine protease inhibitor, inhibited the DNA fragme"tatioll and cell death in MDCK cells treated with ricin, modeccin, Ilseudomonas toxin, or dipbtberia toxin. Atrypsin-like serine protease inhibitor, IVLtosyl・L-lysine chleromethyl ketone (TLCK) also prevented ricin-induced DNA fragmentation and cel] death, albeit less effectiyely than DFP. Microscopi...
