objective: the current methods for bladder cancer diagnosis suffer from low sensitivity and specificity. therefore, finding a novel tumor markers with high specificity and sensitivity is of great interest. micrornas (mirna, mir) are small endogenously-produced, non-coding rnas with an important role in regulating gene expression. recent studies show that mirnas expression profiles represent sig...

Micro RNAS (miRNAs) are a class of endogenous small non coding RNAs involved in the post-transcriptional regulation of gene expression. In plants, a great number of conserved and specific miRNAs, mainly arising from model species, have been identified to date. However less is known about the diversity of these regulatory RNAs in vegetal species with agricultural and/or horticultural importance....

Micro-RNAs (miRNAs) are one class of small non-coding RNAs that have important regulatory roles in higher plants. Much less is known about their prevalence and function in lower land plants. Previously we cloned 100 non-structural small RNAs from the moss Physcomitrella patens but could annotate only 11 as miRNAs. To identify additional moss miRNAs among cloned small RNAs we have analyzed their...

Breast cancer is one of the leading causes death in women. develops from milk-producing cells breast tissue. Exosomes have been linked to proliferation, metastasis, chemoresistance, and carcinogenesis, according research. are membrane-bound extracellular vesicles that can be secreted contain a variety contents such as nucleic acid, protein, lipid, etc. MicroRNAs, component exosomes, small non-c...

Discovery of microRNAs (miRNAs) as negative regulators of gene expression at post-transcriptional level has revealed a new layer of finest regulation of cell signaling mechanisms in normal development and abnormal growth. The pathogenesis in most of the tumors including malignant neuroblastoma, a childhood malignancy in most cases, is now known to be linked to aberrant expression of a wide rang...

Small non-coding RNAs, in particular microRNAs(miRNAs), regulate fine-tuning of gene expression and can act as oncogenes or tumor suppressor genes. Differential miRNA expression has been reported to be of functional relevance for tumor biology. Using next-generation sequencing, the unbiased and absolute quantification of the small RNA transcriptome is now feasible. Neuroblastoma(NB) is an embry...

BACKGROUND MicroRNAs are a class of small noncoding RNAs that are abnormally expressed in different cancer cells. Molecular signature of miRNAs in different malignancies suggests that these are not only actively involved in the pathogenesis of human cancer but also have a significant role in patients survival. The differential expression patterns of specific miRNAs in a specific cancer tissue t...

The process of metabolic re-programing is linked to the activation of oncogenes and/or suppression of tumour suppressor genes, which are regulated by microRNAs (miRNAs). The interplay between oncogenic transformation-driven metabolic re-programming and modulation of aberrant miRNAs further established their critical role in the initiation, promotion and progression of cancer by creating a tumor...

objective(s): study of non-coding rnas is considerable to elucidate principal biological questions or design new therapeutic strategies. mirnas are a group of non-coding rnas that their functions in pi3k/akt signaling and apoptosis pathways after t cell activation is not entirely clear. herein, mirnas expression and their putative targets in the mentioned pathways were studied in the activated ...

UNLABELLED NF-E2-related factor 2 (NRF2) is a master transcriptional regulator that integrates cellular stress responses and is negatively regulated by Kelch-like ECH-associated protein 1 (KEAP1) at the posttranslational level. In human cancers, aberrantly stabilized NRF2, either by mutation of NRF2 or KEAP1, plays a vital role in chemoresistance and tumor cell growth through the transcriptiona...
