Acute lung injury (ALI) is an inflammatory disease with a high mortality rate. Although typically seen in individuals with sepsis, ALI is also a major complication in severe acute pancreatitis (SAP). The pathophysiology of SAP-associated ALI is poorly understood, but elevated serum levels of IL-6 is a reliable marker for disease severity. Here, we used a mouse model of acute pancreatitis-associ...
سابقه و هدف: مطالعات اخیر بیانگر نقش کلیدی miR-221 و miR-21 در سرطان معده می باشند . هر چند دانش ما در مورد مکانیسم مولکولی عملکرد miR-221 و miR- 21 در سرطان بطور کلی و در سرطان معده بطور خاص محدود است. در این مطالعه دو microRNA بالقوه انکوژن (miR-221 و miR-21) انتخاب شده تا ارتباط سطوح بیان این microRNA ها و ژن های هدف آنها در بافت سالم و سرطانی معده مقایسه شوند. هدف این مطالعه بررسی ارتباط بی...
microrna ها گروهی از non-coding rna هاهستند که تعدادی از انها در مکانیسم های پس رونویسی ژن درگیر هستند. تعداد کمی micrornaهای مخصوص عضله شناسایی و نقش آنها در میوژنز، رشد و هایپرتروفی عضلانی مشخص شده است. هدف این مطالعه بررسی تاثیر یک وهله تمرین مقاومتی وامانده ساز بر بیان mir-206 و تعدیل کننده های مثبت و منفی عضله زائی myostatin و myod به ترتیب، در عضلات اسکلتی رت های نر نژاد ویستار بود. 30...
Abstract Background The use of sex-sorted sperm in cattle assisted reproduction is constantly increasing. However, fertility can substantially differ between unsorted (conventional) and semen batches the same sire. Sperm microRNAs (miRNA) have been suggested as promising biomarkers bull last years. In this study, we hypothesized that miRNA profile cryopreserved conventional related to after art...
هدف: تمایز سلولهای بنیادی قلب با کمک میکروrnaها، دریچه جدیدی را برای ترمیم انفارکتوس قلبی گشوده است.mir-1-2/133a-1 و mir-206/133b دو خوشه مجزا از خانواده میکروrnaها هستند که به ترتیب در ماهیچههای قلبی و اسکلتی بیان میشود. چون mir-133b و mir-133a تنها در یک نوکلئوتید اختلاف دارند، احتمالاً مسیرها وmrna های یکسانی را مورد هدف قرار میدهند. هدف تحقیق حاضر، بررسی بیان احتمالی mir-133b در سلوله...
micrornas (mirnas) are a class of small non coding regulatory rnas that have key functions in multiple cell processes. deregulation of these tiny mirnas are involved in various human diseases. mir-155 is one of the multifunctional mirna that its over-expression has been found to be associated with different kinds of cancer such as leukemia, breast and colon cancers. it is thought that deregulat...
The 17th century British physician Thomas Sydenham is credited with saying, “A man is as old as his arteries.” Indeed, aging is associated with myriad structural and functional changes in the cardiovascular system.1 In particular, thoracic aortic aneurysms are commonly found in people during the sixth or seventh decade of life and at a frequency of nearly 1 in 16 000 people per year.2 An aneury...
Geranylgeranyl transferase I (GGTase I), which modifies proteins containing the sequence Cys-Ali-Ali-Leu (Ali: aliphatic) at their C-termini, is indispensable for growth in the budding yeast Saccharomyces cerevisiae. We report here that GGTase I is no longer essential when Rho1p and Cdc42p are simultaneously overproduced. The lethality of a GGTase I deletion is most efficiently suppressed by pr...
Objective(s): Autophagy-related 4B (ATG4B) plays an important role in the process of autophagy induction. However, the molecular events that govern the expression of ATG4B in this process are not well known. Materials and Methods: Human ATG4B 3'-UTR region (1377 nt) containing miR-34a/miR-34c-5p binding site was amplified by PCR. Luciferase assay was used to assess the activity of reporter gene...
Objective(s):MicroRNAs (miRNAs) are a class of short RNAs that control the biological processes including cell proliferation, apoptosis and development. Aberrant expression of miRNAs was determined in the different stages of tumor development and metastasis. To study the effect of silibinin on miRNAs expression, we evaluated quantitative expression of miR-21 and miR-155 as two oncomiRs and seve...
