MicroRNAs (miRNAs) act as key regulators of multiple cancers. MicroRNA-506 (miR-506) functions as a tumor suppressor in various types of cancers. However, its role in esophageal cancer remains unclear. In our study, we found that miR-506 was significantly down-regulated in esophageal cancer tissues and cell lines. In vitro assay, our results showed that ectopic over-expression of miR-506 inhibi...
There is increasing evidence that microRNAs (miRs) are implicated in tumor development and progression; however, their specific roles in osteosarcoma are not well understood. The aim of the present study was to investigate the role of miR-506 in the pathogenesis of osteosarcoma. The expression levels of miR-506 and astrocyte elevated gene-1 (AEG-1) mRNA were detected using quantitative polymera...
Krüppel-like factors (KLFs) regulate a wide variety of cellular functions and modulate pathological processes. In the present study, a post‑translational mechanism of microRNAs (miRs) was investigated in H2O2-induced human cardiomyocyte (HCM) injury. In H2O2‑cultured HCM cells, reactive oxygen species and apoptotic cells were measured via flow cytometry. miR‑506/‑124 mimics and inhibitors were ...
MiRNAs are small noncoding RNAs that play important roles in various biological processes including tumorigenesis. However, little is known about the expression and function of miR-506 in nasopharyngeal carcinoma (NPC). In this study, we showed that miR-506 was downregulated in nasopharyngeal carcinoma (NPC) cell lines and tissues. Ectopic expression of miR-506 dramatically suppressed cell prol...
Ovarian carcinoma is the most lethal gynecologic malignancy. Resistance to platinum is considered the major problem affecting prognosis. Our recent study established that microRNA-506 (miR-506) expression was closely associated with progression-free survival and overall survival in two independent patient cohorts totaling 598 epithelial ovarian cancer cases. Further functional study demonstrate...
Background & Objective: Acute lymphoblastic leukemia (ALL) is a malignant disease that arises from various mutations in B or T-lymphoid progenitors. MicroRNAs (miRNAs) regulate gene expression by binding to the 3' untranslated region of protein-coding genes. Dysregulation of miRNA expression m...
Epithelial-mesenchymal transition (EMT) is an important parameter related to breast cancer survival. Among several microRNAs predicted to target EMT-related genes, miR-506 is a novel miRNA found to be significantly related to breast cancer patient survival in a meta-analysis. miR-506 suppressed the expression of mesenchymal genes such as Vimentin, Snai2, and CD151 in MDA-MB-231 human breast can...
MicroRNAs (miRNAs) are small non-coding RNAs that post-transcriptionally regulate gene expression. They are involved in almost all biological processes, and many have been identified as potential oncogenes or tumor suppressor genes. miR-506 was recently discovered to play pivotal roles in regulating cell proliferation, differentiation, migration and invasion. Dysregulation of miR-506 has been d...
MiRNAs emerge as important regulators of epithelial-to-mesenchymal transition (EMT). The Best known EMT regulatory miRNAs are targeting the transcriptional repressors of E-cadherin (E-cad). We identified miR-506 as a key EMT inhibitor through directly targeting the E-cad transcriptional repressor, SNAI2. Our recent studies showed that miR-506 simultaneously suppresses vimentin and N-cad. Thus, ...
objective(s): ten-eleven translocation (tet) family members have been shown to be involved in the development of many tumors. however, the biological role of the tet family and its mechanism of action in colorectal carcinogenesis and progression remain poorly understood. materials and methods:we measured the expression levels of tet family members in colorectal cancer (crc) specimens, in the co...
