The mammalian target of rapamycin (mTOR) is an intracellular serine/threonine protein kinase positioned at a central point in a variety of cellular signaling cascades. The established involvement of mTOR activity in the cellular processes that contribute to the development and progression of cancer has identified mTOR as a major link in tumorigenesis.(More)
BACKGROUND Beneficial effects of short-term erythropoietin (EPO) therapy have been demonstrated in several animal models of acute neurologic injury, including experimental autoimmune encephalomyelitis (EAE)--the animal model of multiple sclerosis. We have found that EPO treatment substantially reduces the acute clinical paralysis seen in EAE mice and this(More)
Coupling of an antibody response to effector cells through the Fc region of antibodies is a fundamental objective of effective vaccination. We have explored the role of the Fc receptor system in a murine model of Cryptococcus neoformans protection by infecting mice deleted for the common gamma chain of FcRs. Passive administration of an IgG1 mAb protects(More)
Beneficial effects of short-term whole-molecule erythropoietin (EPO) therapy have been demonstrated on several animal models of diverse central nervous system pathology. However, the increased hematocrit induced by EPO-driven marrow stimulation greatly limits its potential for side effect-free therapy. We created a library of EPO-derived fragments based on(More)
BACKGROUND This phase I, randomized, multicenter, open-label study investigated the pharmacokinetics, safety, and efficacy of the oral mammalian target of rapamycin inhibitor everolimus in Chinese patients with advanced solid tumors. METHODS A total of 24 patients with advanced breast cancer (n = 6), gastric cancer (n = 6), non-small cell lung cancer (n =(More)
The current success of targeted inhibition against cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) and Programmed Death 1/Programmed Death Ligand 1 (PD-1/PD-L1, herein collectively referred to as PD) pathways is hailed as a cancer immunotherapy breakthrough. PD-L1, known also as B7 homolog 1 (B7-H1), was initially discovered by Dr. Lieping Chen in(More)
BACKGROUND Most patients with small cell lung cancer (SCLC) or neuroblastoma (NB) already show clinically detectable metastases at diagnosis and have an extremely poor prognosis even when treated with combined modalities. The HuD-antigen is a neuronal RNA-binding protein that is expressed in 100% of SCLC tumor cells and over 50% of neuroblastoma cells. The(More)
Discovery of new treatments for lymphoma that prolong survival and are less toxic than currently available agents represents an urgent unmet need. We now have a better understanding of the molecular pathogenesis of lymphoma, such as aberrant signal transduction pathways, which have led to the discovery and development of targeted therapeutics. The(More)
We report a rare pediatric chronic eosinophilic leukemia (CEL) case of an 8-year-old male whose leukemic cells carried t(1; 5)(q21; q33) chromosomal abnormality. Sequencing analysis confirmed a TPM3-PDGFRB fusion, and the breakpoint was the same as adult patient. Targeted therapy with imatinib induced a rapid hematologic response and reduction of(More)
Journal of Hematology & Oncology is pleased to see the exponential growth in the number of publications from China, especially in hematology and oncology. This editorial calls for putting more weight on the quality of the future scientific output and invites rigorous dialogs among policy makers, granting agencies, academic leaders, physicians, and(More)
