Cryptotanshinone is a biologically active compound from the root of Salvia miltiorrhiza. In the present study, we investigated the molecular mechanisms by which cryptotanshinone is in synergy with tumor necrosis factor-alpha (TNF-α) for the induction of apoptosis in human chronic myeloid leukemia (CML) KBM-5 cells. The co-treatment of cryptotanshinone with(More)
Although the flavonoid icariside II exhibits anti-inflammatory and anti-cancer activities, its molecular targets/pathways in human multiple myeloma cells are poorly understood. To analyze the effects on signal transducer and activator of transcription 3 (STAT3) signaling and apoptosis, U266 multiple myeloma cells were treated with icariside II and performed(More)
BACKGROUND Signal transducer and activator of transcription 3 (STAT3) is a transcription factor that regulates various cellular processes such as cell survival, angiogenesis and proliferation. In the present study, we examined that betulinic acid (BA), a triterpene from the bark of white birch, had the inhibitory effects on hypoxia-mediated activation of(More)
Although tanshinone IIA (Tan IIA) from Salviae miltiorrhizae was known to induce apoptosis in various cancers, its underlying mechanism of autophagic cell death was not reported yet. Thus, in the present study, the molecular mechanism of autophagic cell death by Tan IIA was investigated in KBM-5 leukemia cells. Tan IIA significantly increased the expression(More)
Ergosterol peroxide (EP) derived from edible mushroom has been shown to exert anti-tumor activity in several cancer cells. In the present study, anti-angiogenic activity of EP was investigated with the underlying molecular mechanisms in human multiple myeloma U266 cells. Despite weak cytotoxicity against U266 cells, EP suppressed phosphorylation, DNA(More)
1. The study was performed to predict the pharmacokinetic disposition of bisphenol A in humans using simple allometry and several species-invariant time methods based on animal data. Bisphenol A was injected intravenously to mouse, rat, rabbit and dog (1-2 mg kg(-1) doses). 2. The obtained serum concentration-time profiles were best described by(More)
It has drawn a lot of attention to target signal transducer and activator of transcription 3 (STAT3) as a potential strategy for cancer therapeutics. Using several myelogenous cell lines, the effect of genipin (an active compound of Gardenia fruit) on the STAT3 pathway and apoptosis was investigated. Genipin suppressed the constitutive STAT3 activation in(More)
BACKGROUND Reducing food residue by proper preparation methods before endoscopy after distal gastrectomy can increase the quality of examination and decrease patient discomfort. We evaluated the risk factors for food residue and proper methods of preparation for endoscopy after distal gastrectomy. METHODS Follow-up endoscopy with questionnaires was(More)
We investigated the molecular mechanisms responsible for fisetin-induced apoptosis in U266 cells. Fisetin elicited the cytotoxicity in U266 cells, manifested as an increased fraction of the cells with sub-G1 content or stained positively with TUNEL labeling. Fisetin enhanced caspase-3 activation, downregulation of Bcl-2 and Mcl-1(L), and upregulation of(More)
Special AT-rich sequence-binding protein (SATB) plays a critical role in bone generation and osteoblast differentiation. In the present study, the differentially expressed genes by SATB2 overexpression were analyzed in MC3T3-E1 osteoblast-like cells using Alizarin red S staining, wound healing assay and Agilent's Human Oligo Microarray. Calcium(More)
