A critical regulatory laterality gene expressed in the left side of the straight heart tube during development is Pitx2, which when mutated in humans underlies Rieger's Syndrome. Previously reported results have indicated that, when using gain-of-function and loss-of function approaches of the chick cPitx2c isoform, this results in randomization of heart(More)
Nucleophosmin-mutated acute myeloid leukemia (NPM1mut-AML) patients have a high rate of complete remission (CR) to induction chemotherapy. However, the mechanisms responsible for such effects are unknown. Because miR-10 family members are expressed at high levels in NPM1mut-AML, we evaluated whether these microRNAs could predict chemotherapy response in(More)
BMP signaling plays many important roles during organ development, including palatogenesis. Loss of BMP signaling leads to cleft palate formation. During development, BMP activities are finely tuned by a number of modulators at the extracellular and intracellular levels. Among the extracellular BMP antagonists is Noggin, which preferentialy binds to BMP2,(More)
Chromosome maintenance protein 1 (CRM1) is a nuclear export receptor involved in the active transport of tumor suppressors (e.g., p53 and nucleophosmin) whose function is altered in cancer because of increased expression and overactive transport. Blocking CRM1-mediated nuclear export of such proteins is a novel therapeutic strategy to restore tumor(More)
BACKGROUND "Loss of function" alterations in CCAAT/Enhancer Binding Proteindelta (C/EBPdelta) have been reported in a number of human cancers including breast, prostate and cervical cancer, hepatocellular carcinoma and acute myeloid leukemia. C/EBPdelta gene transcription is induced during cellular quiescence and repressed during active cell cycle(More)
BACKGROUND CCAAT/enhancer binding protein-delta (C/EBP-delta) is a member of the highly conserved C/EBP family of basic region leucine zipper transcription factors. C/EBP family members regulate cell growth and differentiation and "loss of function" alterations in C/EBPs have been reported in a variety of human cancers. C/EBP-delta gene expression is(More)

Lung cancer is one of the most lethal cancers in China because of high incidence and high mortality. Cyclooxygenase-2 (COX-2) and vessel endothelial growth factor C (VEGF-C) were found to play an important role in lymphangiogenesis of malignant tumors. In this study, we investigated whether lymphatic microvessel density (LMVD) is related to the prognosis in(More)
The prognosis of AML is poor, highlighting the need for novel treatments. Hypomethylating agents, including decitabine are used to treat elderly AML patients with relative success. Targeting nuclear exporter receptors (Exportin 1, XPO1) is a novel approach to restore tumor suppressor (TS) function in AML. Here, we show that sequential treatment of AML(More)
The nuclear export receptor, Exportin 1 (XPO1), mediates transport of growth-regulatory proteins, including tumor suppressors, and is overactive in many cancers, including chronic lymphocytic leukemia (CLL), acute myeloid leukemia (AML) and aggressive lymphomas. Oral selective inhibitor of nuclear export (SINE) compounds that block XPO1 function were(More)
Key Points • High miR-10 family expression levels in AML patients are associated with achieving complete remission to induction chemotherapy. • Functional experiments did not show any impact of miR-10a-5p in AML blast growth or survival at baseline conditions or after chemotherapy. Nucleophosmin-mutated acute myeloid leukemia (NPM1mut-AML) patients have a(More)
