Abstract Background and Objective: Various cellular factors affect the process of HIV activity. One of these cellular factors are structures known as microRN that are expected to be involved in controlling HIV replication and infectivity. The expression of one or a set of them may represent the patient's clinical conditions. In this study, ...
Background MicroRNAs (miRNAs) are non-coding RNA molecules (19-24 nucleotides) that play a major role in a wide range of biological processes through post-transcriptional regulation of gene expression. Differential expression of miRNAs has been reported in various infectious diseases such as HIV infection. The characterization of miRNA expression profiles, especially in mammalian biofluids, whi...
Abstract Chronic kidney disease (CKD), characterized by progressive loss of function, is a major cause mortality in cats. Another complication the formation calcium oxalate (CaOx) uroliths bladder and kidneys cats, where inflammation has role its pathogenesis. MicroRNAs (miRNAs) are small non-coding RNAs which bind to target mRNA reduce function. Depending on mRNA, they regulate transcription s...
MiR-103 alleviates autophagy and apoptosis by regulating SOX2 in LPS-injured PC12 cells and SCI rats
Objective(s): Recent studies revealed that microRNAs (miRNAs) may play crucial roles in the responses and pathologic processes of spinal cord injury (SCI). This study aimed to investigate the effect and the molecular basis of miR-103 on LPS-induced injuries in PC12 cells in vitro and SCI rats in vivo. Materials and Methods: PC12 cells were exposed to LPS to induce cell injuries to mimic the in ...
Bladder cancer is the second most common cancer in the genitourinary tract, showing often recurrence and progresse into invasive states. Epigenetic changes, such as microRNA alteration are involved in bladder cancer tumorigenesis through a variety of signaling pathways. The epigenetic state depends on geographic and lifestyle conditions. The aim of this study was to investigate the expression l...
Objective(s): Non-small cell lung cancer (NSCLC) has become a serious global health problem in the 21st century, and tumor proliferation and metastasis are the leading causes of death in patients with lung cancer. The present study aimed to verify the function of miR-96 and miR-96 in relation to competing with endogenous RNA regulatory network in NSCLC progression inc...
Abstract Background and Objectives Platelets release microparticles containing cellular components, including microRNAs, during storage. Assessment of these microRNAs is one of the markers for evaluation of platelet storage lesions. The aim of the present study was to evaluate the level of changes in the expression of mir-223, mir-92a and mir-222 during storage in platelets prepared by platele...
Introduction: In clinical practice, distinguishing invasive lung tumors from primary tumors remains a challenge. With recent advances in understanding biological alterations of tumorigenesis and molecular analytic technologies, using these molecular alterations can be sensitive and tumor-specific as biomarker for the stratification of patients. In this study, the molecular network of miRNA-mRNA...
در ایران سالیانه ???? مورد جدید سرطان مثانه و ???? مورد مرگ و میر ناشی از آن گزارش میشود. سرطان مثانه سومین سرطان شایع در بین مردان و دهمین سرطان شایع در بین زنان کشورمان است. اقدامات درمانی برای این سرطان در صورت تشخیص زودرس به احتمال زیاد موفقیت آمیز خواهد بود، در حقیقت زمانی که سرطان پیشرفت نکرده و بافت های پیرامون را درگیر نکرده باشد. در سال های اخیر پژوهشگران در پی یافتن مارکر مولکولی مناس...
downs syndrome (ds), or trisomy 21, is the most common genetic cause of cognitive impairment and congenital heart defects in the human population. to date, the contribution of micrornas (mirnas) in ds has not been investigated. bioinformatic analyses demonstrate that human chromosome 21 (hsa21) harbors five mirna genes mir-99a, let-7c, mir-125b-2, mir-155 and mir-802. mirna expression profiling...
