Increase in activity and level of pp60c-src in progressive stages of human colorectal cancer.
Activation of the tyrosine kinase of the c-src gene product, pp60c-src, has been shown to occur in nearly every primary colorectal carcinoma, and is found as early as in polyps of high malignant potential. However, no studies have addressed potential pp60c-src changes which occur during progression. To examine this question, we have studied kinase activity and protein levels in 7 colonic polyps...
متن کاملActivity of pp60c-src protein kinase in human breast cancer.
Because there is elevation of pp60c-src activity in breast carcinoma tissue, we analyzed primary breast cancer tissue samples from 30 women to determine whether pp60c-src activity correlated with specific clinical parameters. We found that tumors with a progesterone receptor had higher pp60c-src activity than tumors without such a receptor. But there was no association of pp60c-src activity wit...

چکیده: سرطان پستان دومین عامل مرگ مرتبط با سرطان در خانم ها است. از آنجا که سرطان پستان یک تومور وابسته به هورمون است، می تواند توسط وضعیت هورمون های استروئیدی شامل استروژن و پروژسترون تنظیم شود. استروژن نقش مهمی در توسعه و پیشرفت سرطان پستان ایفا می کند و تاثیر خود را روی بیان ژن های هدف از طریق گیرنده های استروژن اعمال می کند. اما گروه دیگری از گیرنده های هسته ای به نام گیرنده های مرتبط به ا...
15 صفحه اولcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولHigh pp60c-src level in human platelet dense bodies.
Phosphoproteins phosphorylated in vivo were examined in resting and thrombin-activated human blood platelets. Thrombin-stimulation resulted in an overall increase in labeled proteins containing phosphotyrosine. The most prominent was a protein of 60 Kd. By electroblotting, the 60 Kd protein was identified as the pp60c-src, the normal cellular homolog of the transforming protein of Rous sarcoma ...
