Adrenocortical carcinoma (ACC) is an aggressive tumor showing frequent metastatic spread and poor survival. Although recent genome-wide studies of ACC have contributed to our understanding of the disease, major challenges remain for both diagnostic and prognostic assessments. The aim of this study was to identify specific microRNAs (miRNAs) associated with malignancy and survival of ACC patient...

The differential expression of the petunia 1-aminocyclopropane-1-carboxylate (ACC) oxidase gene family during flower development and senescence was investigated. ACC oxidase catalyzes the conversion of ACC to ethylene. The increase in ethylene production by petunia corollas during senescence was preceded by increased ACC oxidase mRNA and enzyme activity. Treatment of flowers with ethylene led t...

PURPOSE To investigate the difference of expression of autophagy and reactive oxygen species (ROS) related proteins in adenoid cystic carcinoma (ACC) of lacrimal gland in comparison with ACC of salivary gland. MATERIALS AND METHODS Formalin-fixed, paraffin-embedded tissue samples from patients pathologically diagnosed as lacrimal gland ACC (n=11) and salivary gland ACC (n=64) were used. Immun...

PURPOSE Adrenocortical carcinoma (ACC) is an endocrine malignancy with a poor prognosis. The association of adult-onset ACC with inherited cancer predisposition syndromes is poorly understood. Our study sought to define the prevalence of Lynch syndrome (LS) among patients with ACC. PATIENTS AND METHODS One hundred fourteen patients with ACC were evaluated in a specialized endocrine oncology c...

since the discovery of macc as a major metabolite of both endogenous and exogenously applied acc, it has become evident that the formation of macc from acc can act to regulate ethylene production in certain tissues. hence, it was suggested that macc could serve as an indicator of water-stress history in plant tissues. the accurate quantification of macc in plant tissues is essential for the und...

آنزیم acc deamiase با تبدیل acc به آمونیوم و ? -کتوبوتیرات میزان هورمون گیاهی اتیلن را کاهش می دهد. این آنزیم در گروهی از باکتری ها ی همزیست با گیاهان که به باکتری های pgpb )باکتری های افزایش دهنده رشد گیاهان( معروف هستند شناسایی شده است. آنزیم acc deaminase به وسیله ژن acds کد می شود. سیستم تنظیمی منحصر به فردی بیان ژن acds را کنترل می کند که شامل فاکتور های تنظیمی عمومی مانند crp و fnr به ...

مقدار اتیلن در شرایط تنشی به میزان قابل توجهی در گیاه افزایش پیدا می¬کند و باعث پیری زودرس گیاه می¬گردد. برخی از باکتریهای محرک رشد گیاه حاوی آنزیمی به نام acc deaminase هستند که قادر است 1-آمینوسیکلوپروپان-1-کربوکسیلات (acc) که پیش¬ماده مستقیم اتیلن در گیاهان است را به آمونیوم و آلفاکتوبوتیرات تبدیل و از این طریق موجب کاهش سطح اتیلن ناشی از تنش شود. در این تحقیق 330 سویه ریزوبیوم از چهار گروه ...
