In this study radioimmunoassay, immunohistochemistry, Northern blot analysis, and a gel overlay technique have been used to examine the level, subcellular distribution, and potential target proteins of the S100 family of calcium-modulated proteins in adult and developing rat skeletal muscles. Adult rat muscles contained high levels of S100 proteins but the particular form present was dependent ...
BACKGROUND Mating changes the mechanism by which E2 regulates oviductal egg transport, from a non-genomic to a genomic mode. Previously, we found that E2 increased the expression of several genes in the oviduct of mated rats, but not in unmated rats. Among the transcripts that increased its level by E2 only in mated rats was the one coding for an s100 calcium binding protein G (s100 g) whose fu...
The phenotypic effects of selectively decreasing the levels of S100 beta in cultured glial cells were analyzed. Two separate antisense approaches were utilized for inhibition of S100 beta production: analysis of clonal isolates of rat C6 glioma cells containing an S100 beta antisense gene under the control of a dexamethasone-inducible promoter, and analysis of C6 cells treated with S100 beta an...
An S100 binding protein from skeletal muscle, R95 000, has been purified, identified as glycogen phosphorylase, and shown to be regulated in vitro by the S100 alpha isoform. When a soluble skeletal muscle fraction was subjected to a standard purification procedure for glycogen phosphorylase, R95 000 copurified with the 95 000 molecular weight glycogen phosphorylase protein standard on SDS-polya...
To understand better the mechanisms involved in the transduction of a calcium signal into an intracellular response via multiple calcium-modulated proteins, we have examined the calcium-modulated proteins, S100 and calmodulin, and their intracellular targets in rat C6 glioma cells. Subconfluent, confluent, and postconfluent C6 cells contain predominantly, if not exclusively, the S100 beta polyp...
The beta-subunit of S100 protein (S100 beta) is highly conserved in the mammalian brain. The gene coding for human S100 beta has been mapped to chromosome 21. In order to study the consequences of overexpression of the S100 beta gene, transgenic mice were generated by microinjection of a 17.3 kilobase human genomic fragment containing the three exons and the transcription control elements of th...
PURPOSE To study the expression of S100 A and B family proteins in normal human limbus and to analyze modification of the expression in inflammatory conditions. METHODS The total expression of members of the S100 family and the expression of A4, A8, A9, and B individually were evaluated in nine normal human corneal limbi, collected from cadaver healthy donors, in particular in the limbal epit...
هدف تحقیق: ورزش های برخوردی با امکان رخداد ضربه به سر و آسیب های مغزی همراه می باشند که در بوکس میزان بروز ضربه مغزی و صدمات به سر بیش از هر ورزش دیگر گزارش شده است با این حال، بررسی این موضوع با استفاده از شاخص های معتبر خونی تاکنون کمتر انجام شده است. هدف این پژوهش تعیین اثر یک جلسه مسابقه بوکس بر تغییرات ،s-100 b پروتئین واکنش گر crp )c و لکوسیت ها در بوکسورهای زبده بود. روش تحقیق: آزمودنی ه...
به منظور بررسی اثر سیلی مارین بر ذخیره سازی اسپرم خروس در oc 4 از 15 قطعه خروس بالغ استفاده شد. جمع آوری منی دو بار در هفته در 5 نوبت انجام شد. انزال ها در هر نوبت بعد از تجمیع به پنج قسمت تقسیم شد. مقدار صفر (شاهد، s0)، 50 (s50)، 100 (s100)، 150 (s150) و 200 (s200) میکروگرم در میلی لیتر سیلی مارین به هر قسمت اضافه شد. سپس نمونه ها تا oc 4 سرد شد و به مدت 72 ساعت در این دما نگهداری شد. در زمان ...
