Anaplastic large cell lymphoma (ALCL) is an aggressive lymphoma that is frequently associated with the t(2;5)(p23;q35), resulting in expression of a fusion protein, nucleophosmin-anaplastic lymphoma kinase (NPM-ALK), which can be detected by either monoclonal or polyclonal antibodies to the ALK protein. The clinical features of adults with ALCL are(More)
Quantitative susceptibility mapping (QSM) is a new technique for quantifying magnetic susceptibility. It has already found various applications in quantifying in vivo iron content, calcifications and changes in venous oxygen saturation. The accuracy of susceptibility mapping is dependent on several factors. In this review, we evaluate the entire process of(More)
P53 is a tumor suppressor gene and plays important roles in the etiology of breast cancer. Studies revealing conflicting results on the role of p53 codon 72 polymorphism (G>C) on breast cancer risk led us to perform a meta-analysis to investigate this relationship. Thirty-nine published studies, including 26,041 breast cancer cases and 29,679 controls were(More)
The identification of molecules that regulate human hematopoietic stem cells has focused mainly on cytokines, of which very few are known to act directly on stem cells. Recent studies in lower organisms and the mouse have suggested that bone morphogenetic proteins (BMPs) may play a critical role in the specification of hematopoietic tissue from the(More)
Human telomerase reverse transcriptase (TERT) is essential for the maintenance of telomere DNA length, chromosomal stability and cellular immortality. We hypothesized that TERT polymorphisms are associated with risk of childhood acute lymphoblastic leukemia (ALL). We first conducted a case-control study of 570 ALL cases and 673 cancer-free controls of(More)
Genetic variations in miRNAs have been demonstrated to be capable of altering miRNA expression, consequently affecting many cancer-related biological processes. The MIR196A2 rs11614913 (T > C) polymorphism has been reported to be associated with various cancers development and progression. In our study, we aim to explore whether this polymorphism is(More)
Axon degeneration is an active program of self-destruction observed in many physiological and pathological settings. There are three Nicotinamide mononucleotide adenylyl transferase (Nmnat, EC2.7.7.1) in mammals. Overexpression of Nmnat1 or Nmnat3 can delay axon degeneration, while the role of Nmnat2 in axon degeneration remains largely unknown. Here we(More)
The Notch ligand, Jagged-1, plays an essential role in tissue formation during embryonic development of primitive organisms. However, little is known regarding the role of Jagged-1 in the regulation of tissue-specific stem cells or its function in humans. Here, we show that uncommitted human hematopoietic cells and cells that comprise the putative blood(More)
Historically, appendicitis in the elderly is associated with higher morbidity and mortality. Ninety-six patients over 60 years of age with appendicitis treated over a 10-year period were reviewed. Only 20% presented classically with anorexia, fever, right lower quadrant pain, and an elevated white blood cell count. One third of the patients had greater than(More)
The intracellular signaling controlling neural stem/progenitor cell (NSC) self-renewal and neuronal/glial differentiation is not fully understood. We show here that Shp2, an introcellular tyrosine phosphatase with two SH2 domains, plays a critical role in NSC activities. Conditional deletion of Shp2 in neural progenitor cells mediated by Nestin-Cre resulted(More)
