Disruption of Runx1/AML1 subnuclear localization, either by a single amino acid substitution or by a chromosomal translocation [e.g., t(8;21)], is linked to the etiology of acute myeloid leukemia (AML). Here, we show that this defect induces a select set of micro-RNAs (miR) in myeloid progenitor cells and AML patients with t(8;21). Both Runx1 and the t(8;21)encoded AML1-ETO occupy the miR-24-23...
Coordinated repression of gene expression by evolutionarily conserved microRNA (miRNA) clusters and paralogs ensures that miRNAs efficiently exert their biological impact. Combining both loss- and gain-of-function genetic approaches, we show that the miR-23∼27∼24 clusters regulate multiple aspects of T cell biology, particularly helper T (Th) 2 immunity. Low expression of this miRNA family conf...

Rationale: Failing cardiomyocytes exhibit decreased efficiency of excitation-contraction (E-C) coupling. The downregulation of junctophilin-2 (JP2), a protein anchoring the sarcoplasmic reticulum to T-tubules, has been identified as a major mechanism underlying the defective E-C coupling. However, the regulatory mechanism of JP2 remains unknown. Objective: To determine whether microRNAs regulat...

Background and Purpose: MicroRNAs are small non-coding RNAs with 1924- nucleotides in length. Up- or downregulation of many miRNAs has been shown by stimulation of Toll-like receptors (TLRs) in the innate immune system. Up-regulation of miR-146a has been reported by both TLR and heat-killed Candida albicans. In this study, we aimed to evaluate the expression of miR-146a in cultured monocyte-...
microRNAs, a family of small non-coding RNAs, regulating approximately 30% of all human genes are deeply involved in the pathogenesis of several types of cancers, including laryngeal squamous cell carcinoma (LSCC). Here, we demonstrate that miR-24 is down-regulated in human LSCC tissues. Ectopic expression of miR-24 in Hep2 cells significantly induced cell morphology changes and inhibited cell ...
esophageal squamous cell carcinoma (escc) is a deadly cancer with poor prognosis. in this regard, early diagnosis is of vital importance to cure the tumor in its early stages. novel cancer diagnostic and therapeutic approaches have been recently introduced based on micrornas (mirnas). also, accurate normalization using appropriate reference genes is a critical step in mirna expression studies. ...
Breast cancer is a leading cause of related death among women worldwide and it complex disease characterized by its heterogeneity. The heterogenous characteristic the breast responsible for aggressiveness treatment resistance. stem cells (BCSCs) are population with increased propensity proliferation, differentiation, migration, invasion mammosphere formation resistance to treatment. They have a...
Cardiomyocyte cell death is a major contributing factor to various cardiovascular diseases and is therefore an important target for the design of therapeutic strategies. More recently, stem cell therapies, such as transplantation of embryonic or induced pluripotent stem (iPS) cell-derived cardiomyocytes, have emerged as a promising alternative therapeutic avenue to treating cardiovascular disea...
