BACKGROUND/AIMS Abnormal expression of microRNA-124 (miR-124) was found in non-small cell lung cancer (NSCLC). However, the association between miR-124 and CDH2 has not been reported yet. This study aims to reveal the inhibiting effects of miR-124 on the expression of CDH2 in NSCLC. METHODS Quantitative real-time polymerase chain reaction was used to evaluate the expression of miR-124 and CDH...

MicroRNAs (miRs) have been implicated in tumorigenesis through inhibition of the expression of their target genes at post-transcriptional levels. miR-124 has been found to be downregulated in many malignant tumors including osteosarcoma (OS). However, the detailed mechanism of miR-124 in the regulation of OS malignant phenotypes remains largely unclear. Here we aimed to explore the role of miR-...

MicroRNAs play critical roles in regulating various physiological processes, including growth and development. Previous studies have shown that microRNA-124 (miR-124) participates not only in regulation of early neurogenesis but also in suppression of tumorigenesis. In the present study, we found that overexpression of miR-124 was associated with reduced DNA repair capacity in cultured cancer c...

BACKGROUND The Health Professions Council of South Africa requires that a research project be submitted and passed before registration as a specialist. METHOD Ethics clearance was received before commencing the study. A questionnaire was developed to collect feedback from surgical registrars throughout South Africa (SA). Completed questionnaires underwent descriptive analysis using MS Excel. ...

BACKGROUND I-124 codrituzumab (aka GC33), an antibody directed at Glypican 3, was evaluated in patients with hepatocellular carcinoma (HCC). Fourteen patients with HCC underwent baseline imaging with I-124 codrituzumab (~ 185 MBq, 10 mg). Seven of these patients undergoing sorafenib/immunotherapy with 2.5 or 5 mg/kg of cold codrituzumab had repeat imaging, with co-infusion of I-124 codrituzumab...

The aim of the present study was to investigate the clinical significance of hsa-microRNA-124-3p (miR-124) in osteosarcoma (OS), and examine its role in cell growth and invasion. Using a microRNA chip array, the expression of miR-124 was detected in samples of surgically resected OS and matched against the levels of expression in tumor-adjacent normal tissues. The levels of miR-124 were upregul...

BACKGROUND Glioma is one of the most aggressive and lethal human brain tumors. Accumulating evidence shows that microRNAs play important roles in cancers, including glioma. Previous studies reported that miR-124 levels were downregulated in glioma specimens. Here, we further investigate the potential role of miR-124 in glioma. METHODS The expression levels of miR-124 were detected in glioma s...

It is currently known that estrogen plays an important role in breast cancer (BC) development, but the underlying molecular mechanism remains to be elucidated. Accumulating evidence has revealed important roles of microRNAs in various kinds of human cancers, including BC. In this study, we found that among the microRNAs regulated by estrogen, miR-124 was the most prominent downregulated miRNA. ...

RATIONALE Pulmonary hypertensive remodeling is characterized by excessive proliferation, migration, and proinflammatory activation of adventitial fibroblasts. In culture, fibroblasts maintain a similar activated phenotype. The mechanisms responsible for generation/maintenance of this phenotype remain unknown. OBJECTIVE We hypothesized that aberrant expression of microRNA-124 (miR-124) regulat...

MicroRNA-124 (miR-124) has been demonstrated to be downregulated in numerous human malignancies and correlated with tumor progression. However, its expression and clinical significance in osteosarcoma remains unclear. Thus, the aim of the present study was to explore the effects of miR-124 in osteosarcoma tumorigenesis and development. Using reverse transcription-quantitative polymerase chain r...
