PURPOSE The ER chaperone GRP78 translocates to the surface of tumor cells and promotes survival, metastasis, and resistance to therapy. An oncogenic function of cell surface GRP78 has been attributed to the activation of the phosphoinositide 3-kinase (PI3K) pathway. We intend to use a novel anti-GRP78 monoclonal antibody (MAb159) to attenuate PI3K signaling(More)
Axl is an oncogenic receptor tyrosine kinase that plays multiple roles in tumorigenesis and metastasis of many cancers. This study is the first to demonstrate that Axl is induced in Kaposi sarcoma and Kaposi sarcoma herpesvirus (KSHV) transformed endothelial cells. Conditionally, expression of one KSHV latency protein vFLIP induces Axl expression in(More)
In the present study, we investigated the neuroprotection of simvastatin in PC12 cells following 1-methyl-4-phenylpyridinium ion (MPP+) neurotoxicity. Simvastatin inhibited the decrease of cell viability induced by MPP+ in PC12 cells. The damage of PC12 cells in morphology was alleviated and the apoptotic rates were decreased due to simvatatin pretreatment(More)
Cardiac anomaly is one of the hallmarks of DiGeorge syndrome (DGS), observed in approximately 80% of patients. It often shows a characteristic morphology, termed as conotruncal heart defects. In many cases showing only the conotruncal heart defect, deletion of 22q11.2 region cannot be detected by fluorescence in situ hybridization (FISH), which is used to(More)

Acute lymphoblastic leukaemia (ALL) in infants is an intractable cancer in childhood. Although recent intensive chemotherapy progress has considerably improved ALL treatment outcome, disease cure is often accompanied by undesirable long-term side effects, and efficient, less toxic molecular targeting therapies have been anticipated. In infant ALL cells with(More)
