Background: Safe and effective gene therapy is considered as one of the therapeutic goals in many diseases. Due to the important role of stem cells in cell therapy, this study aimed to produce human adipose-derived mesenchymal stem cells (hASCs) using the miR-34a overexpression. Materials and methods: The hsa-mir-34a precursor sequence was cloned into the PCDH lentiviral vector. The recombinant...
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...
Objective(s): Autophagy-related 4B (ATG4B) plays an important role in the process of autophagy induction. However, the molecular events that govern the expression of ATG4B in this process are not well known. Materials and Methods: Human ATG4B 3'-UTR region (1377 nt) containing miR-34a/miR-34c-5p binding site was amplified by PCR. Luciferase assay was used to assess the activity of reporter gene...
Objective This study aimed to investigate the correlations of long non-coding RNA ANRIL (lncRNA ANRIL), microRNA (miR)-34a, miR-125a and miR-186 with disease risk, clinical features prognosis multiple myeloma (MM).Method Totally, 87 MM patients 30 controls were recruited. LncRNA its target miRNAs (miR-34a, miR-186) in bone marrow derived plasma cells detected by RT-qPCR. Treatment response was ...
MicroRNA-34a (miR-34a) is a master regulator of signaling networks that maintains normal physiology and disease and is currently in development as a miRNA-based therapy for cancer. Prior studies have reported low miR-34a expression in osteosarcoma; however, the molecular mechanisms underlying miR-34a activity in osteosarcoma are not well-defined. Therefore, this study evaluated the role of miR-...
BACKGROUND MicroRNAs (miRs) are small non-coding RNAs that play an important role in cancer development where they can act as oncogenes or as tumor-suppressors. miR-34a is a tumor-suppressor that is frequently downregulated in a number of tumor types. However, little is known about the role of miR-34a in head and neck squamous cell carcinoma (HNSCC). METHODS AND RESULTS miR-34a expression in ...
MiR-34a, a direct target of p53, has shown to exert potent anti-proliferative effects. It has also been found that miR-34a can be induced by irradiation in vitro and in vivo. However, the relationship between miR-34a and radio-sensitivity, and its potential diagnostic significance in radiation biology, remain unclear. This study found that differing responses to ionizing radiation (IR) of young...
MicroRNA-34a (miR-34a) is thought to be involved in nonalcoholic fatty liver disease (NAFLD). However, the association between altered expression of miR-34a and the pathophysiological features of NAFLD remains unclear. Here, we investigated the mechanisms by which miR-34a influences NAFLD through the PPARα-related pathway. Real-time quantitative PCR, western blotting and other assays kit were u...
MiR-34a is a well-known tumor metastasis inhibitor, but only a few target genes involved in metastasis have been identified. In HNSCC, the role of miR-34a in metastasis has not been fully elaborated, and the target gene of miR-34a is still blind. Here we addressed that, the relative lower expression of miR-34a is associated with HNSCC lymphatic metastasis. HNSCC metastasis was found to be stron...
پیشینه: لوسمی لنفوبلاستیک حاد T-cell (T-ALL) یک بدخیمی لنفوئیدی است که به علت دگرگونی اونکوژنیک اجدادT-cell ایجاد می شود. بسیاری از تغییرات ژنتیکی و اپی ژنتیکی به عنوان فاکتور های اصلی این دگرگونی بیان شده اند. اخیرا گزارش شده است که microRNA ها در لوسمی های مختلف از جمله T-ALL نقش دارند. بیان نابجای این microRNA ها در تکثیر، تهاجم و آپوپتوز از طریق هدف قرار دادن مسیر های سیگنالی گزارش شده است....
