background micrornas are small and non-coding rna molecules with approximately 22 nt in length that cause inhibition of translation or degradation of mrna. mir-155 is a kind of molecule with different functions, such as its role in proliferation, apoptosis, inflammation, differentiation, and immunity. one of its best known functions is apoptosis that affects on caspase-3 activity. the main aim ...
Background: MicroRNA-155 (miR-155) is upregulated during T cell activation, but the exact mechanisms by which it influences CD4+ T cell activation remain unclear. Objective: To examine whether the B and T lymphocyte attenuator (BTLA) is a target of miR-155 during naïve CD4+ T cell activation. Methods: Firefly luciferase reporter plasmids pEZX-MT01-wild-type-BTLA and pEZX-MT01-mutant-BTLA were ...
conclusions the mir-155 appeared to be suppressed during hbv infection. the significantly higher mir-155 levels in alt-elevated patients infected with hbv suggest that mir-155 levels in pbmcs correlate with the immune state of patients with chronic hbv infection. results in the hbv-infected patients, the mir-155 levels were significantly lower than in the healthy controls (p = 0.001). chronic h...
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...
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...

چکید ه سابقه و هدف میکرو rna ها، نوعی از rna های کوچک غیر کدکننده هستند و اخیراً مشخص شده که نقشی اساسی در فرآیندهای مهم سلولی از جمله تکامل و تمایز از طریق تنظیم پس از رونویسی، ایفا می کنند. میزان بیان میکرو rna ها در ارتباط با بیماری زایی بعضی بدخیمی های خونی از جمله لوسمی میلوئیدی حاد شناخته شده است . هدف از این مطالعه، بررسی بیان mir-150 و mir-155 در بیماری لوسمی میلوژنوس مزمن( cml ) بود...
Introduction MicroRNA-155 (miR-155) is an oncogenic microRNA, which is upregulated in many human cancers including colorectal cancer (CRC). Overexpression of miR-155 has been found to regulate several cancer-related pathways, and therefore, targeting miR-155 may be an effective strategy for cancer therapy. However, effective and safe delivery of anti-miR-155 to tumors remains challenging for th...
Background: Gastric cancer (GC) is one of the most prevalent cancers with a high rate of mortality in the world. In recent years, microRNAs (miRNAs) have been proposed to be involved in GC development. In this study, we aimed at investigating differential expression level of miR-155-5p, miR-15a, miR-15b, and miR-186 in GC. Methods: For this research, we used qPCR to investigate miR-15b, miR-155...
