ACTH-independent macronodular adrenal hyperplasia is a rare cause of Cushing's syndrome (CS), accounting for <2% of all endogenous CS cases; however it is more frequently identified incidentally with sub-clinical cortisol secretion. Recently, cortisol secretion has been shown to be regulated by ectopic corticotropin, which is in turn produced by clusters of steroidogenic cells of the hyperplast...
OBJECTIVE Primary macronodular adrenal hyperplasia (PMAH) is a rare type of Cushing's syndrome (CS) that results in increased cortisol production and bilateral enlargement of the adrenal glands. Recent work showed that the disease may be caused by germline and somatic mutations in the ARMC5 gene, a likely tumor suppressor gene (TSG). We investigated 20 different adrenal nodules from one patient...
Somatic GNAS point mutations, commonly known as gsp mutations, are involved in the pathogenesis of McCune-Albright syndrome (MAS) and have also been described in autonomous hormone-producing tumors, such as somatotropinoma, corticotrophoma, thyroid cancer, ovarian and testicular Leydig cell tumors, and primary macronodular adrenocortical hyperplasia (PMAH) (1-3). The involvement of gsp mutation...
Although many rhodamine based fluorescence sensors were reported to detect metal ions with high sensitivity and selectivity, there are very few reports available to study the mechanisms of detection and the interaction between probe and metal ions. This paper aims to detect ferric ions by novel fluorescence chemosensors and study the mechanisms in detail. A novel probe AD-MAH-RhB was designed a...
strr یک تنظیم کننده کلیدی در رونویسی خوشه ژنی بیوسنتز آنتی بیوتیک استرپتومایسین است. این پروتئین توسط ژن strr استرپتومایسس گریزئوس با طول 1053 جفت باز کد می شود. هدف این تحقیق، کلونینگ ژن strr از سویه استرپتومایسس گریزئوس ایرانی ptcc1127 و همچنین atcc1952 درناقل pma::hyg بود. برای این منظور پرایمرهای اختصاصی ژن strr با نرم افزار oligo طراحی شدند، قطعه با طول 1134جفت باز به روش pcr تکثیر شد. سپس...
