The aim of this study was to determine the anticancer effects of seven licorice compounds in MKN-28, AGS, and MKN-45 gastric cancer cells and human gastric epithelium immortalized cells. We also explored the mechanism of action of licochalcone A (LCA), the most cytotoxic licorice compound, by analyzing its influence on cell cycle progression and apoptosis.(More)
PURPOSE Hepatocellular carcinoma (HCC) is the third most common cause of cancer-related death, and iron overload is a significant risk factor in the development of HCC. In this study, we investigated the potential application of depriving iron by a novel iron chelator, thiosemicarbazone-24 (TSC24), in HCC treatment. EXPERIMENTAL DESIGN Two HCC cell lines(More)
Ginseng is one of the most commonly used herbal medicines worldwide. Ginsenosides are believed to be responsible for the therapeutic activities of ginseng; however, co-administration of prescription drugs with ginseng products may give rise to ginseng-drug interactions. Cytochrome P450 enzymes are major phase I enzymes involved in the metabolism of most(More)
Artemisinin and its main active metabolite dihydroartemisinin, clinically used antimalarial agents with low host toxicity, have recently shown potent anticancer activities in a variety of human cancer models. Although iron mediated oxidative damage is involved, the mechanisms underlying these activities remain unclear. In the current study, we found that(More)
Considerable efforts have been made to the development of small-molecule inhibitors of antiapoptotic B-cell lymphoma 2 (Bcl-2) family proteins (such as Bcl-2, Bcl-xL , and Mcl-1) as a new class of anticancer therapies. Unlike general inhibitors of the entire family, selective inhibitors of each member protein can hopefully reduce the adverse side effects in(More)
Extraribosomal functions of ribosomal proteins (RPs) have gained much attention for their implications in tumorigenesis and progression. However, the regulations for transition between the ribosomal and extraribosomal functions of RPs are rarely reported. Herein, we identified a ribosomal protein S7-interacting partner, BCCIPβ, which modulates the(More)
Antiapoptotic Bcl-2 family proteins, such as Bcl-xL , Bcl-2, and Mcl-1, are often overexpressed in tumor cells, which contributes to tumor cell resistance to chemotherapies and radiotherapies. Inhibitors of these proteins thus have potential applications in cancer treatment. We discovered, through structure-based virtual screening, a lead compound with(More)
Benzo(a)pyrene is a common environmental and foodborne pollutant that has been identified as a human carcinogen. Although the carcinogenicity of benzo(a)pyrene has been extensively reported, its precise molecular mechanisms and the influence on system-level protein networks are not well understood. To investigate the system-level influence of benzo(a)pyrene(More)

Mitochondria-targeting theranostic probes that enable the simultaneously reporting of and triggering of mitochondrial dysfunctions in cancer cells are highly attractive for cancer diagnosis and therapy. Three fluorescent mitochondria-targeting theranostic probes have been developed by linking a mitochondrial dye, coumarin-3-carboximide, with a widely used(More)
