BACKGROUND We have previously shown that hsa-miR-520d-5p can convert cancer cells into induced pluripotent stem cells (iPSCs) or mesenchymal stem cells (MSCs) via a dedifferentiation by a demethylation mechanism. METHODS We tested the effect of miR-520d-5p on human fibroblasts to determine whether it could be safely used in normal cells for future clinical therapeutic applications. After we t...
UNLABELLED Development of improved RNA interference-based strategies is of utmost clinical importance. Although siRNA-mediated silencing of EphA2, an ovarian cancer oncogene, results in reduction of tumor growth, we present evidence that additional inhibition of EphA2 by a microRNA (miRNA) further "boosts" its antitumor effects. We identified miR-520d-3p as a tumor suppressor upstream of EphA2,...
MicroRNAs are key players in most biological processes. Some microRNAs are involved in the genesis of tumors and are therefore termed oncomiRs, while others, termed metastamiRs, play a significant role in the formation of cancer metastases. Previously, we identified ten different cellular microRNAs that downregulate the expression of MICB, a ligand of the activating NK receptor NKG2D. Interesti...
MiR-520d-3p has recently been reported to have anti-tumor function in several cancers, including glioma and gastric cancer. However, the biological its mechanism of action remain unclear cervical cancer (CC). In this study, we observed that miR-520d-3p expression was lowly expressed CC specimens compared with adjacent normal using reverse transcription quantitative PCR. Moreover, low correlated...
Background: Breast cancer is the most common cancer in women. Non-coding RNAs especially miRNAs have important regulatory roles in cancer. MiRNAs are 21-24 nucleotides which have different levels of expression between tumors and normal tissues. In this study, we have analyzed expression level of miR-520d in three different groups of breast cancer.Methods: Fifty nine samples were divided into di...
The transcription factor TAL1 is a proto-oncogene whose aberrant expression in committed T-cell precursors is associated with the development of T-cell acute lymphoblastic leukemia (T-ALL). The mechanisms leading to aberrant activation of TAL1 in T-ALL patients who lack chromosomal rearrangements involving the TAL1 locus remain largely unknown. We hypothesized that TAL1 levels decrease during n...
The human ncRNA gene RGM249 regulates the extent of differentiation of cancer cells and the conversion of 293FT cells to hiPSCs. To identify the factors underlying this process, we investigated the effects of lentivirally inducing miR-520d expression in 293FT and HLF cells in vitro. Subsequently, we evaluated tumor formation in a xenograft model. Transformed HLF cells were Oct4 and Nanog positi...

زمینه و هدف: ریز rnaها 21 تا 24 نوکلئوتید دارند و بیان بعضی از آن ها در بین بافت نرمال و توموری متفاوت است. در این مطالعه ما بیان mir-520d را در بین گروه های توموری سرطان پستان با نمونه نرمال کنار آن مورد بررسی قرار دادیم.روش بررسی: 59 نمونه تومور سرطان پستان در سه گروه مختلف قرار داده شدند. در گروه اول نمونه های دارای رسپتور استروژن مثبت و یا رسپتور پروژسترون مثبت قرار گرفتند. در گروه دوم نمون...
