MicroRNA is known to be an important regulator of gene expression. The microRNAs that were found to be differentially expressed in normal urothelium and urothelial carcinomas in the literature were selected and meaningful microRNAs were validated using urothelial tumor cells lines; formalin-fixed and paraffin-embedded (FFPE) tissues; and urine samples for both the definitely benign and malignan...
BACKGROUND MicroRNAs are key transcriptional and network regulators previously associated with asthma susceptibility. However, their role in relation to asthma severity has not been delineated. OBJECTIVE We hypothesized that circulating microRNAs could serve as biomarkers of changes in lung function in asthma patients. METHODS We isolated microRNAs from serum samples obtained at randomizati...
While microRNAs have been shown to copurify with polysomes, their relative fraction in the translation pool (polysome occupancy) has not yet been measured. Here, we introduce a high-throughput method for quantifying polysome occupancies of hundreds of microRNAs and use it to investigate factors affecting these occupancies. Analysis in human embryonic stem cells (hESCs) and foreskin fibroblasts ...
Most animals have separate sexes. The differential expression of gene products, in particular that of gene regulators, is underlying sexual dimorphism. Analyses of sex-biased expression have focused mostly on protein-coding genes. Several lines of evidence indicate that microRNAs, a class of major gene regulators, are likely to have a significant role in sexual dimorphism. This role has not bee...
MicroRNAs a category of noncoding RNA dysregulations are involved in numerous pathological conditions including cancer, diabetes, heart diseases, immunological disorders, neurological diseases and many metabolic diseases. Advancement the knowledge microRNA applications led to diagnosis some early markers Currently innovative molecular biotechnology is holding promising future field application ...
Exosomes, as a mediator of cell-to-cell transfer of genetic information, act an important role in intercommunication between tumor cells and their niche including fibroblasts, endothelial cells, adipocytes and monocytes. Several studies have shown that tumor cells can influence their neighboring cells by releasing exosomes. These exosomes provide signaling cues for stimulation, activation, prol...
microRNAs are small, noncoding RNAs that control gene/protein expression through target messengerRNA degradation and/or inhibition of protein synthesis. An array of experimental studies has shown the importance of microRNAs for disease initiation/progression. microRNAs are generally considered to act as intracellular modulators of gene expression. However, first studies in the cancer and cardio...
objective: infection with herpes simplex virus type 1 induces viral latency in neuron trigeminal ganglions. the late associated transcript (lat) is uniquely expressed in infected neural cells, however no coding protein associated with these transcripts has been identified in infected cells. it has been shown that six micrornas transcribed from lat have the capabilities to affect the cell signal...
PURPOSE MicroRNAs are short noncoding RNAs that regulate gene expression and are over- or underexpressed in most tumors, including colorectal adenocarcinoma. MicroRNAs are potential biomarkers and therapeutic targets and agents, but limited information on microRNAome alterations during progression in the well-known adenoma-adenocarcinoma sequence is available to guide their usage. EXPERIMENTA...
BACKGROUND MicroRNAs are a class of small RNAs known to regulate gene expression at the transcript level, the protein level, or both. Since microRNA binding is sequence-based but possibly structure-specific, work in this area has resulted in multiple databases storing predicted microRNA:target relationships computed using diverse algorithms. We integrate prediction databases, compare prediction...
