Background: A growing body of literature has revealed the effective role of miR-34a, as a tumor suppressor and regulator of expression of multiple targets in tumorigenesis and cancer progression. This study aimed at evaluating the potential effects of miR-34a alone or in combination with paclitaxel on breast cancer cells. Methods: After miR-34a transduction by lentiviral vectors in two MCF-7 an...

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-der...

bladder cancer (bc) ranks the second most common genitourinary tract malignant tumor with high mortality and 70% recurrence rate worldwide. mirnas expression has noticeable role in bladder tumorigenesis. the purpose of this study was to assess mir-200c, mir-30b and mir-141 in tissue samples of patients with bc and healthy adjacent tissue samples and their association with muscle invasion, grade...

Objective(s):miR-125b has been identified as a tumor suppressor in many tumors, but its role in giant cell tumor (GCT) of bone remains poorly understood. The current study aimed to investigate the potential role and mechanism of miR-125b in GCT. Materials and Methods:Expression levels of miR-125b in GCT tissues were determined using RT-PCR. The cell proliferation was surveyed by direct cell coun...

  Objective(s): Erythropoiesis is regulated by some extrinsic and intrinsic factors as microRNAs (miRNAs). miRNAs are endogenously small non-coding regulatory RNAs which play vital roles in the variety of cellular fate, critical processes; growth, apoptosis, metabolism, survival of the cells and specially differentiation. Several miRNAs such as miR-16 and miR-451 have been shown to be correlate...

Background and Aims: Multiple sclerosis (MS) has been assumed to be a complex and indecipherable disease, and poorly understood with regard to etiology which is characterized by relapses and remissions. The expression of microRNAs (miRNAs) is known to be associated with the regulation of immune responses. Recently, investigations have reported that miRNA expression profiles in blood cells becom...

MicroRNAs has been shown to regulate lipogenesis in liver. The aim of the present study was to investigate whether the effects of resveratrol (RSV) on lipogenesis is associated with the changes in the expression of two miRNAs (miR-107 and miR-10b) that regulate lipogenic pathways. 30 wild type C57BL/6j male mice were randomly fed three diets: a standard chow diet (ND), a high fat diet (HFD, 60%...
