Diffuse large B-cell lymphoma (DLBCL) is a heterogeneous group of B-cell lymphomas. A new and important tool for understanding the biology and clinical course of DLBCL is microRNA expression. This study presents microRNA-200c expression data from 61 DLBCL patients treated with CHOP or R-CHOP. Patients with high microRNA-200c expression had a media...
RATIONALE MicroRNAs modestly suppress their direct mRNA targets, and these direct effects are amplified by modulation of gene transcription pathways. Consequently, indirect mRNA modulatory effects of microRNAs to increase or decrease mRNAs greatly outnumber direct target suppressions. Because microRNAs are products of transcription, the potential exists for microRNAs that regulate transcription...
For the analysis of microRNA, a common approach is to first extract microRNA from cellular samples prior to any specific microRNA detection. Thus, it is important to determine the quality and yield of extracted microRNA. In this study, solid-phase extraction was used to isolate small RNA (<200 nt), which included microRNA, from mouse brain tissues. By using standard UV absorbance measurements, ...
BACKGROUND Cardiac hypertrophy and subsequent heart failure triggered by chronic hypertension represent major challenges for cardiovascular research. Beyond neurohormonal and myocyte signaling pathways, growing evidence suggests inflammatory signaling pathways as therapeutically targetable contributors to this process. We recently reported that microRNA-155 is a key mediator of cardiac inflamma...
MicroRNA-375 is involved in many types of alimentary system cancers. Our previous studies showed that microRNA-375 was significantly down-regulated in carcinoma tissues compared with para-carcinoma tissues, which strongly indicates that microRNA-375 might suppress the occurrence and development of colorectal cancer. However, the mechanism underlying the microRNA-375 regulation in colorectal can...
سرطان سینه با وقوع بیش از 5000 مرگ در سال، هنوز از عوامل مهم مرگ ومیر است. با پیدایش فرضیه سلول های بنیادی سرطانی، محققان همواره به دنبال بررسی هدف های ممکن برای از بین بردن آنها بوده اند. این سلول ها، سلول های تمایز نیافته داخل بافت توموری هستند که دارای ویژگی خودتکثیری و توانایی ایجاد تومور جدید می باشند. همچنین این سلول ها به شیمی درمانی و رادیودرمانی مقاومند. ویژگی اخیر دلیل بازگشت تومور پس...
Extensive work has been dedicated to study mechanisms of microRNA-mediated gene regulation. However, the transcriptional regulation of microRNAs themselves is far less well understood, due to difficulties determining the transcription start sites of transient primary transcripts. This challenge can be addressed using expression quantitative trait loci (eQTLs) whose regulatory effects represent ...
BACKGROUND The aim of this study was to assess the differences in microRNA 21 expression among neuroblastoma (NB), embryonic tissue, and normal adrenal tissue and to identify correlations between microRNA 21 expression, the biological features of the tumor, and prognosis. METHODS A total of 70 patients with NB were selected from December 2005 and December 2007. Real-time polymerase chain reac...
MicroRNAs are pivotal regulators of development and cellular homeostasis. They act as post-transcriptional regulators, which control the stability and translation efficiency of their target mRNAs. The prediction of microRNA targets and detection of microRNA-mRNA regulatory modules (MRMs) are crucial components for understanding of microRNA functions. Numerous computational methods for microRNA ...
