Posttranscriptional regulation of the asialoglycoprotein receptor by cGMP.
The human asialoglycoprotein receptor expressed by the HepG2 cell line is composed of the two homologous polypeptides H1 and H2. Transblot analysis of HepG2 cell lysates indicated that the progressive loss in the steady-state level of asialoglycoprotein receptor (ASGR) when cells were maintained in medium supplemented with dialyzed fetal bovine serum was reversed by the addition of cell-permean...
متن کاملPhosphorylation of the human asialoglycoprotein receptor.
The human asialoglycoprotein receptor was isolated via immune precipitation from hepatoma Hep G2 cells following incubation with [32P]Pi. Analysis on sodium dodecyl sulphate/polyacrylamide-gel electrophoresis revealed incorporation of 32P into both the 46 000 Da mature form of the receptor as well as the 40 000 Da precursor. The incorporated 32P was associated with phosphoserine. The degree of ...

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولTranscriptional down-regulation of the human alpha2C-adrenergic receptor by cAMP.
The heterologous regulation of the alpha2C-adrenergic receptor (alpha2C-AR) was investigated in the HepG2 cell line. Binding of [(3)H]MK912 (alpha2-antagonist) to membranes from cells submitted to various treatments showed that exposure to insulin, phorbol 12-myristate 13-acetate, or dexamethasone did not affect receptor density. On the other hand, treatment with forskolin resulted in a large r...
