BACKGROUND Transcription factors play a key role in lineage commitment and differentiation of stem cells into distinct mature cells. In hematopoiesis, they regulate lineage-specific gene expression in a stage-specific manner through various physical and functional interactions with regulatory proteins that are simultanously recruited and activated to ensure timely gene expression. The transcrip...

RNA Binding Proteins Anna M. Eiring *1 Abstract Altered microRNA (miRNA) expression contributes to aberrant post-transcriptional gene regulation in several types of cancers; however, their role in the progression of chronic myeloid leukemia (CML) from chronic phase (CML-CP) to blast crisis (CML-BC) is still largely unknown. To gain further insight into the role of miRNAs in CML disease progress...

BACKGROUND DNA methyltransferase 1 (Dnmt1) regulates expression of many critical genes through maintaining parental DNA methylation patterns on daughter DNA strands during mitosis. It is essential for embryonic development and diverse biological processes, including maintenance of hematopoietic stem and progenitor cells (HSPCs). However, the precise molecular mechanism of how Dnmt1 is involved ...

GATA2 plays a crucial role for the mast cell fate decision. We herein demonstrate that GATA2 is also required for the maintenance of the cellular identity in committed mast cells derived from mouse bone marrow (BMMCs). The deletion of the GATA2 DNA binding domain (GATA2ΔCF) in BMMCs resulted in a loss of the mast cell phenotype and an increase in the number of CD11b- and/or Ly6G/C-positive cell...

C/EBPa protein domains The basic region leucine zipper domain mediates DNA binding, homodimerization of C/EBPa and heterodimerization with other members of the C/EBP family. This region is also involved in mediating protein-protein interactions with other transcription factors involved in lineage determination and growth proliferation. N-terminal region transactivating domains mediate interacti...

Huntington's disease is a progressive neurodegenerative disorder characterized by motor disturbances, cognitive decline, and neuropsychiatric symptoms. In this study, we utilized network-based analysis in an attempt to explore and understand the underlying molecular mechanism and to identify critical molecular players of this disease condition. Using human post-mortem microarrays from three bra...

Background: Targeting of CD20 antigen with monoclonal antibodies has become the mainstay in the treatment of non-Hodgkin's lymphomas and immunotherapeutic depletion of malignant B cells. Accessibility of antigen is one of the crucial factors in development of monoclonal antibodies against this antigen. One major problem in expression of full length CD20 is aggregation and misfolding. Therefore,...

When the fading channels are encountered during data communication, errors likely to occur at receiving end due multipath propagation. Researchers have been consistently striving develop Error Correction Schemes that can effectively handle these and ensure error-free reception receiver end. Of particular interest Forward be implemented transmitter itself. However, implementation of error correc...

Groupers of the family Epinephelidae are a diverse and economically valuable group of reef fishes. To investigate the evolution of their mitochondrial genomes we characterized and compared these genomes among 22 species, 17 newly sequenced. Among these fishes we identified three distinct genome organizations, two of them never previously reported in vertebrates. In 19 of these species, mitochon...
