In the past decade, no significant improvement has been made in chemotherapy for osteosarcoma (OS). To develop improved agents against OS, we screened 70 species of medicinal plants and treated two human OS cell lines with different agent concentrations. We then examined cell viability using the MTT assay. Results showed that a candidate plant, particularly(More)
The route guidance system, which provides driving advice based on traffic information about an origin and a destination, has become very popular along with the advancement of handheld devices and the global position system. Since the accuracy and efficiency of route guidance depend on the accuracy of the traffic conditions, the route guidance system needs(More)
UNLABELLED Aim/Materials and Methods: In order to develop better drugs against non-small cell lung cancer (NSCLC), we screened a variety of compounds and treated the human lung adenocarcinoma cell line A549 with different drug concentrations. We then examined the cell viability using the MTT assay. RESULTS Data show that a new candidate drug, acriflavine(More)
Recent reports demonstrate that the expression of protein kinase C alpha (PKCα) in triple-negative breast cancer (TNBC) correlates with decreased survival outcomes. However, off-target effects of targeting PKCα and limited understanding of the signaling mechanisms upstream of PKCα have hampered previous efforts to manipulate this ubiquitous gene. This study(More)
Patients suffering from advanced hepatocellular carcinoma can generally be treated only by targeted therapy to achieve a survival rate that lasts a few months more than that achieved with conventional therapy. To develop better drugs against hepatocellular carcinoma, we screened a variety of compounds and treated four human hepatocellular carcinoma (HCC)(More)
AXL receptor tyrosine kinase is overexpressed in triple-negative breast cancer (TNBC), and has a function in cancer progression and metastases. However, the mechanism underlying AXL gene regulation in TNBC remains unknown. In this study, the involvement of protein kinase C α (PKCα) in the expression of AXL was investigated in human TNBC cells. The(More)
Background: Protein kinase C alpha (PKCα) is a key signaling molecule in human cancer development. As a therapeutic strategy, targeting PKCα is difficult because the molecule is ubiquitously expressed in non-malignant cells. PKCα is regulated by the cooperative interaction of the transcription factors myeloid zinc finger 1 (MZF-1) and Ets-like protein-1(More)
