Alzheimer's disease (AD) and age-related macular degeneration (AMD) are complex and progressive inflammatory degenerations of the human neocortex and retina. Recent molecular, genetic and epigenetic evidence indicate that at least 4 micro RNAs (miRNAs) - including the NF-кB-regulated miRNA-9, miRNA-125b, miRNA-146a and miRNA-155 - are progressively up-regulated in both AD and AMD. This quartet ...

Motivation: MicroRNAs (miRNAs) play critical roles in gene regulation. Although it is well known that multiple miRNAs may work as miRNA modules to synergistically regulate common target mRNAs, the understanding of miRNA modules is still in its infancy. Results: We employed the recently generated high throughput experimental data to study miRNA modules. We predicted 181 miRNA modules and 306 pot...

MicroRNAs (miRNAs) are evolutionary conserved, small non-coding RNA with size ranging from 19 to 24 nucleotides. They endogenously regulate the gene expression at the post transcriptional level either through translation repression or mRNA degradation. MiRNAs have shown the potential to be used as a biomarker for the diagnosis, prognosis, and therapy of infectious diseases. Many miRNAs have sho...

BACKGROUND The purpose of this study was to evaluate the potential value of circulating miRNA-122a and miRNA-221 in the diagnosis of hepatocellular carcinoma. METHODS Serum samples were obtained from 85 patients with hepatocellular carcinoma and 85 age-matched and sex-matched healthy volunteers. miRNAs were isolated from the serum samples, and alfa-fetoprotein levels were determined. Expressi...

BACKGROUND MicroRNAs (miRNAs) are responsible for regulating proliferation, differentiation, apoptosis, invasion, and metastasis in tumor cells. miRNA-506 is abnormally expressed in multiple tumors, indicating that it might be oncogenic or tumor-suppressive. However, little is known about the association between miRNA-506 expression and esophageal squamous cell carcinoma (ESCC). MATERIAL AND ME...

With respect to upstream regions of microRNA (miRNA) target sites located in protein coding sequences, experimental studies have suggested rare codons, rather than frequent codons, are important for miRNA function, because they slow down the local translational process. But, whether there is a trend of reduced translation efficiency near miRNA targets is still unknown. Using Arabidopsis thalian...

زمینه و هدف: mirna های مرتبط با متاستاز حوزه جدیدی از درمان های متاستاز بر اساس mir را ایجاد کرده که پتانسیل درمانی بالایی برای کشنده ترین جنبه سرطان، یعنی متاستاز دارد. mir-31 یک mirna ضد متاستازی با عملکرد پلیوتروپیک است که بیان آن در سلول های متاستاتیک سرطان پستان به طور قابل توجهی کاهش می یابد. این mirna در چندین مرحله از آبشار متاستازی نقش دارد و استفاده از روش های بازیافت mir-31 می تواند ...

Purpose: MicroRNA-21 (miRNA-21) has proto-oncogenic properties, although no miRNA-21–specific targets have been found in head and neck squamous cell carcinoma (HNSCC). Further study of miRNA-21 and its specific targets is essential to understanding HNSCC biology. Experimental Design:miRNA expression profiles of 10 HNSCCs and 10 normal mucosa samples were investigated using a custom miRNA microa...

MicroRNA (miRNA or miR) therapeutics in cancer are based on targeting or mimicking miRNAs involved in cancer onset, progression, angiogenesis, epithelial-mesenchymal transition and metastasis. Several studies conclusively have demonstrated that miRNAs are deeply involved in tumor onset and progression, either behaving as tumor-promoting miRNAs (oncomiRNAs and metastamiRNAs) or as tumor suppress...
