مقدمه: microrna ها یک نوع rna با طول بین 20 تا 24 نوکلئوتید می باشند که نقش های تنظیمی مهمی را در سلول ها ایفا می کنند. mir-211 یکی از microrna هایی است که بیان آن در سلول های سرطانی به ویژه ملانوما انسانی کاهش می یابد و نقش مهمی را در مهار رشد و تهاجم تومور ایفا می کند. تاکنون مقایسه ای بر روی بیان mir-211 در ملانومای موشی در شرایط in vitro و in vivo صورت نگرفته است. در این مطالعه، ما به ارزیا...
Increasing evidence has demonstrated that microRNA (miRNA) serve an important role in the tumorigenesis of various types of cancer, such as renal cell carcinoma (RCC). The expression of miR-211-5p has been detected in RCC tissue by microarray profiling. However, studies regarding miR-211-5p and RCC remain rare. In the present study, the expression of miR-211-5p in RCC tissues and cell lines was...
The immediate molecular mechanisms behind invasive melanoma are poorly understood. Recent studies implicate microRNAs (miRNAs) as important agents in melanoma and other cancers. To investigate the role of miRNAs in melanoma, we subjected human melanoma cell lines to miRNA expression profiling, and report a range of variations in several miRNAs. Specifically, compared with expression levels in m...
Recent studies have shown that microRNAs play a pivotal role in the pathogenesis of cancer. In our current study, the expression levels of microRNA-211 (miR-211) were measured in human non-small-cell lung cancer (NSCLC) tissues and cell lines. We found that miR-211 expression levels were increased in NSCLC tissues and cell lines and that the overexpression of miR-211 promotes cell proliferation...
When it escapes early detection, malignant melanoma becomes a highly lethal and treatment-refractory cancer. Melastatin is greatly downregulated in metastatic melanomas and is widely believed to function as a melanoma tumor suppressor. Here we report that tumor suppressive activity is not mediated by melastatin but instead by a microRNA (miR-211) hosted within an intron of melastatin. Increasin...
Angiopoietin‑1 (ANG‑1), a ligand of the endothelial cell‑specific TIE2 surface receptor, acts in a complementary and coordinated manner with vascular endothelial growth factor during the process of angiogenesis. ANG‑1 can be used as a clinically informative biomarker of disease severity and outcome in severe sepsis. The epithelium‑specific Ets transcription factor 1 can activate ANG‑1 transcrip...
The complex molecular mechanisms involved in the development and progression of cutaneous malignant melanoma remain incompletely understood. Small 22-nucleotide microRNAs (miRNAs), which are becoming increasingly known to be associated with tumorigenesis, may now offer insight into the aggressively invasive behavior of melanoma. This new class of small RNAs targets mRNA turnover and translation...
سرطان مری ششمین عامل مرگ و میرهای ناشی از سرطان در دنیا می باشد. استان گلستان در شمال شرقی ایران یکی از قطب¬های جهانی با شیوع بالای سرطان مری از نوع کارسینومای سلول سنگفرشی (escc) محسوب می¬شود. مکانیسم¬های مولکولی دخیل در این بیماری هنوز بطور دقیق شناخته نشده است. اخیرا نقش mirnaها در پاتوژنز سرطانها نشان داده شده است. در این تحقیق، پروفایل بیانی بیش از هفتصد mirna در نمونه¬های بافتی پارافینه ک...
The non-coding microRNAs (miRNA) have tissue- and disease-specific expression patterns. They down-regulate target mRNAs, which likely impacts on most fundamental cellular processes. Differential expression patterns of miRNAs are currently being exploited for identification of biomarkers for early disease diagnosis, prediction of progression for melanoma and other cancers and as promising drug t...
MiR-204 and miR-211 (miR-204/211) share the same seed site sequence, targeting many of the same genes. Their role in cancer development remains controversial, as both cell proliferative and suppressive effects have been identified. This study aimed to address the relationship between the two structurally similar microRNAs (miRs) by examining their target genes in depth as well as to reveal thei...
