زمینه و هدف: mirna های مرتبط با متاستاز حوزه جدیدی از درمان های متاستاز بر اساس mir را ایجاد کرده که پتانسیل درمانی بالایی برای کشنده ترین جنبه سرطان، یعنی متاستاز دارد. mir-31 یک mirna ضد متاستازی با عملکرد پلیوتروپیک است که بیان آن در سلول های متاستاتیک سرطان پستان به طور قابل توجهی کاهش می یابد. این mirna در چندین مرحله از آبشار متاستازی نقش دارد و استفاده از روش های بازیافت mir-31 می تواند ...
Hepatitis B viral infection-induced hepatocellular carcinoma is one of the major problems in the developing countries. One of the HBV proteins, HBx, modulates the host cell machinery via several mechanisms. In this study we hypothesized that HBV enhances cell proliferation via HBx-induced microRNA-21 in hepatocellular carcinoma. HBx gene was over-expressed, and miRNA-21 expression and cell prol...
The interaction of 784 intergenic (ig-miRNA), 686 intronic (in-miRNA) and 49 exonic miRNAs (ex-miRNA) with mRNAs of 51 oncogenes coding in-miRNAs was investigated. Out of the studied genes, 44 were targets for 94 ig-miRNAs, 29 were targets for 44 in-miRNAs and 7 were targets for 7 ex-miRNAs. The density of miRNA binding sites was higher in 5'-untranslated regions than it was in coding sequences...
Direct control of microRNA (miRNA) expression by oncogenic and tumor suppressor networks results in frequent dysregulation of miRNAs in cancer cells and contributes to tumorigenesis. We previously demonstrated that activation of the c-Myc oncogenic transcription factor (Myc) broadly influences miRNA expression and in particular leads to widespread miRNA down-regulation. miRNA transcripts repres...
Neurodegenerative Parkinson's disease (PD) is a multi-factorial disorder lacking complete cure. Understanding the complete mechanism of initiation and progression of this disease has been quite challenging; however, progress has been made toward deciphering certain genetic aspects related to the disease condition. Genetics studies have provided clues toward the role of microRNAs (miRNAs) in var...
MicroRNAs are small, non-coding sequences that regulate gene expression by inducing degradation or translational inhibition of target mRNAs. These molecules control many intracellular physiological and pathological processes.Abnormal expression of these moleculs has been described in different cancers including hematopoietic cancers. According to the type of cancer and the stage, miRNA’s expres...
Wound healing is a complex and well-orchestrated process to keep our skin intact. This delicate repair often gets disrupted in patients with underlying causes. However, the effective wound therapy lacking due limited knowledge of related molecular pathogenesis. In this study, we performed paired small RNA (miRNA) long (circular mRNA) sequencing human tissue samples, including matched acute woun...
The let-7 miRNA regulates developmental timing in C. elegans and is an important paradigm for investigations of miRNA functions in mammalian development. We have examined the role of miRNA precursor processing in the temporal control and lineage specificity of the let-7 miRNA. In situ hybridization (ISH) in E9.5 mouse embryos revealed early induction of let-7 in the developing central nervous s...
BACKGROUND Detection of pancreatic cancer (PaC), particularly at early stages, remains a great challenge owing to lack of specific biomarkers. We sought to identify a PaC-specific serum microRNA (miRNA) expression profile and test its specificity and sensitivity as a biomarker in the diagnosis and prognosis of PaC. METHODS We obtained serum samples from 197 PaC cases and 158 age- and sex-matc...
