BACKGROUND MiR-221 and miR-222 (miR-221/222) are frequently up-regulated in various types of human malignancy including glioblastoma. Recent studies have reported that miR-221/222 regulate cell growth and cell cycle progression by targeting p27 and p57. However the underlying mechanism involved in cell survival modulation of miR-221/222 remains elusive. (More)
MiR-221 and miR-222 (miR-221/222), upregulated in gliomas, can regulate glioma cell cycle progression and apoptosis, respectively. However, the association of miR-221/222 with glioma cell invasion and survival remains unknown. Invasion capability of miR-221/222 was detected by mutiple analyses, including diffusion tensor imaging (DTI), transwell, wound(More)
The long non-coding RNA Hox transcript antisense intergenic RNA (HOTAIR) was recently implicated in breast cancer metastasis and is predictive of poor prognosis in colorectal and pancreatic cancers. We recently discovered that HOTAIR is a cell cycle-related lncRNA in human glioma, and its expression is closely associated with glioma staging and poor(More)
The Wnt/β-catenin signaling pathway is crucial for human organ development and is involved in tumor progression of many cancers. Accumulating evidence suggests that the expression of β-catenin is, in part, regulated by specific microRNAs (miRNAs). The purpose of this study was to determine the expression of a recently(More)
Identification of molecular pathways that are essential for cancer cell survival is vital for understanding the underlying biology, as well as to design effective cancer therapeutics. β-catenin, a multifunctional oncogenic protein, participates in cell development. Its multifaceted functions primarily lie to the subcellular distribution. The present study(More)
Epidermal growth factor receptor (EGFR) is amplified in 40% of human glioblastomas. However, most glioblastoma patients respond poorly to anti-EGFR therapy. MicroRNAs can function as either oncogenes or tumor suppressor genes, and have been shown to play an important role in cancer cell proliferation, invasion and apoptosis. Whether microRNAs can impact the(More)
BACKGROUND AND AIMS The nuclear localization of β-catenin, a mediator of canonical Wnt signaling, has been indicated in a variety of cancers and is frequently related to tumor progression and metastasis. Therefore, targeting β-catenin is an attractive therapeutic strategy for cancers. METHODS Herein, we identified a natural, small molecule inhibitor of(More)
BACKGROUND AND AIMS Currently temozolomide (TMZ) as a potent agent is widely used to treat the glioblastoma multiforme (GBM), whereas recurrence due to intrinsic or acquired therapeutic resistance often occurs. Combination chemotherapy with TMZ may be a promising therapeutic strategy to improve treatment efficacy. METHODS Aspirin, TMZ, and(More)
Feature location is a software comprehension activity which aims at identifying source code entities that implement functionalities. Manual feature location is a labor-insensitive task, and developers need to find the target entities from thousands of software artifacts. Recent research has developed automatic and semiautomatic methods mainly based on(More)
