microRNA miR-221 is frequently over-expressed in a variety of human neoplasms. Aim of this study was to identify new miR-221 gene targets to improve our understanding on the molecular tumor-promoting mechanisms affected by miR-221. Gene expression profiling of miR-221-transfected-SNU-398 cells was analyzed by the Sylamer algorithm to verify the enrichment of miR-221 targets among down-modulated...

Glioblastoma is the most common type of primary brain tumor in adults, with high mortality and morbidity rates. More effective therapeutic strategies are imperative. Previous studies have shown that the known p110-β-selective inhibitor TGX-221 blocks the activation of PKB/Akt in PTEN-deficient cells. We treated U87 and U251 glioblastoma cells with TGX-221 to determine the effect of TGX-221. We ...

A rising body of evidence suggests that silencing microRNAs (miRNAs) with oncogenic potential may represent a successful therapeutic strategy for human cancer. We investigated the therapeutic activity of miR-221/222 inhibitors against human multiple myeloma (MM) cells. Enforced expression of miR-221/222 inhibitors triggered in vitro anti-proliferative effects and up-regulation of canonic miR-22...

MicroRNA-221 and microRNA-222 (miR-221/222) have been identified as oncogenes and confirmed to be overexpressed in various types of cancer. However, the regulation mechanism of miR-221/222 in oral squamous cell carcinoma (OSCC) remains to be fully elucidated. Previously, an miR-221/222 sponge was successfully constructed and its effect on the downregulation of miR-221/222 expression was investi...

MicroRNA (miRNA-221) has been reported to be a regulator of cell proliferation. Here we intended to investigate the role of miRNA-221 in regulating the growth of human non-small cell lung cancer cell line H460. H460 cells were transfected with miRNA-221 mimics/inhibitors or their respective negative controls. Real-time quantitative PCRs (qRT-PCRs) were used to confirm the effects of miRNA-221 m...

UNLABELLED MicroRNAs (miRNAs) are small, noncoding RNA molecules that control expression of target genes. The abnormally expressed miRNAs function as oncogenes or tumor suppressors in human cancer. To evaluate the abundant gene regulation of miR-221 in papillary thyroid carcinoma (PTC), we performed microarray analysis and developed a Gaussia luciferase (Gluc) reporter system regulated by miR-2...

Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related death. Gene therapy was established as a new strategy for treating HCC. To explore the potential delivery system to support the gene therapy of HCC, negatively charged liposomal delivery system was used to deliver miR-221 antisense oligonucleotide (anti-miR-221) to the transferrin (Tf) receptor over expressed HepG2 ce...
