Tanshinone I (Tan-I) is a diterpene quinone extracted from the traditional herbal medicine Salvia miltiorrhiza Bunge. Recently, Tan-I has been reported to have anti-tumor effects. In this study, we investigated the growth inhibition and apoptosis inducing effects of Tan-I on three kinds of monocytic leukemia cells (U937, THP-1 and SHI 1). Cell viability was(More)
Nowadays, drug resistance still represents a major obstacle to successful acute myeloid leukemia (AML) treatment and the underlying mechanism is not fully elucidated. Here, we found that high expression of c-Myc was one of the cytogenetic characteristics in the drug-resistant leukemic cells. c-Myc over-expression in leukemic cells induced resistance to(More)
Peroxisome proliferator-activated receptor gamma (PPARγ) plays an important role in regulating energy balance, glucose and lipid metabolisms and inflammation. PPARγ also exerts multiple anti-cancer effects including tumor growth and angiogenesis inhibition, induction of cell differentiation, and apoptosis. Perturbed Wnt/β-catenin signaling likely plays a(More)
Chronic myelogenous leukemia (CML) is a hematological stem cell disorder. Tyrosine kinase inhibitors (TKIs) are the standard treatments for CML, but a number of patients fail to respond effectively due to gene mutations. Celecoxib, a cyclooxygenase-2 (COX-2) inhibitor, has been shown to have anti-tumor effect on solid tumor whereas the anti-CML effect and(More)
Elevated β-amyloid (Aβ) is a hallmark of Alzheimer’s disease (AD). Recent evidence has suggested that the receptor of advanced glycation end products (RAGE) is a key target for Aβ-induced perturbation in AD, and blockade of RAGE significantly alleviates synaptic injury. Our previous study has suggested that β-asarone could reduce neuronal apoptosis and(More)
The combination of all-trans retinoic acid (ATRA) and arsenic trioxide (As2O3, ATO) has been effective in obtaining high clinical complete remission (CR) rates in acute promyelocytic leukemia (APL), but the long-term efficacy and safety among newly diagnosed APL patients are unclear. In this retrospective study, total 45 newly diagnosed APL patients(More)
