the manipulation of redox potential in secretory pathway by thiol reducing agents can be a strategy to improve the production levels of disulfide-bonded proteins including recombinant antibodies. here we have studied the influence of cysteamine on viability and the production level of igg4 in sp2.0 cells. for this purpose, the recombinant sp2.0 cells producing an anti cd33 igg4, were subjected ...
بررسی بیان ژنهای دخیل در سیستم دفاعی گندم نسبت به mycosphaerella graminicola با استفاده از cdna-aflp
aflp یک ابزار قدرتمند برای تشخیص رونوشت هایی با فراوانی کم است و می تواند بعنوان یک روش کارآمد برای جداسازی ژنهایی که بطور متمایز بیان می شوند، بکار رود. بنابراین القا متمایز ژنها در گندم ( رقم چمران و مرودشت) در پاسخ به قارچ m.graminicola بوسیله آنالیز cdna-aflp مورد مطالعه قرار گرفت . در ابتدا گیاهان بوسیله بیمارگر مایه زنی شدند. نمونه برداری در 6 نقطه زمانی(0، 12، 24، 48، 72 و 96 ساعت) بعد ا...
The study of thrombus formation has increasingly applied in vivo tools such as genetically modified mice and intravital microscopy to the evaluation of molecular and cellular mechanisms of thrombosis. Among several unexpected findings of this approach was the discovery that protein disulfide isomerase serves an essential role in thrombus formation at sites of vascular injury. The observation th...
Newly synthesized membrane and secretory proteins in cells undergo folding the endoplasmic reticulum with introduction of disulfide bonds acquire correct three-dimensional structure. Disulfide are especially important for protein folding. It has been thought that formation eukaryotes is mainly carried out by an enzyme called isomerase. Proteins, bearing C-terminus amino acids sequences His-Asp-...
The release of protein disulfide isomerase by activated platelets was hypothesized on the basis of reported intermolecular and intramolecular thiol-disulfide exchange and disulfide reduction involving released thrombospondin in the supernatant solution of activated platelets (Danishefsky, Alexander, Detwiler: Biochemistry, 23:4984, 1984; Speziale, Detwiler: J Biol Chem, 265:17859, 1990; Spezial...
OBJECTIVE Staphylococcus aureus can induce platelet aggregation. The rapidity and degree of this correlates with the severity of disseminated intravascular coagulation, and depends on platelet peptidoglycans. Surface-located thiol isomerases play an important role in platelet activation. The staphylococcal extracellular adherence protein (Eap) functions as an adhesin for host plasma proteins. T...
The transport and intraluminal reduction of dehydroascorbate was investigated in microsomal vesicles from various tissues. The highest rates of transport and intraluminal isotope accumulation (using radiolabeled compound and a rapid filtration technique) were found in hepatic microsomes. These microsomes contain the highest amount of protein-disulfide isomerase, which is known to have a dehydro...
The thiol-disulfide oxidoreductase ERp57 is a soluble protein of the endoplasmic reticulum and the closest known homologue of protein disulfide isomerase. The protein interacts with the two lectin chaperones calnexin and calreticulin and thereby promotes the oxidative folding of newly synthesized glycoproteins. Here we have characterized several fundamental structural and functional properties ...
