, 2006 DNA looping plays a fundamental role in a wide variety of biological processes, providing the backbone for long range interactions on DNA. Here we develop the first model for DNA looping by an arbitrarily large number of proteins and solve it ...

Molecular Oncology, EarlyView.Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.

Harnessing DNA Binding Proteins from Starved Cells for DNA Origami Protection
Small StructuresDNA origami is an attractive method for building structurally versatile and addressable nanostructures for diverse applications. The structural integrity of DNA, however, is rather limited in application‐relevant environments, such as in low‐magnesium ...

Gadd45a is an RNA binding protein and is localized in nuclear speckles.
PLoS ONE, 2011 BackgroundThe Gadd45 proteins play important roles in growth control, maintenance of genomic stability, DNA repair, and apoptosis. Recently, Gadd45 proteins have also been implicated in epigenetic gene regulation by promoting active DNA demethylation ...

Human Cytomegalovirus UL34 Early and late Proteins Are Essential for Viral Replication
Viruses, 2014 UL34 is one of the ~50 genes of human cytomegalovirus (HCMV) required for replication in cell culture in human fibroblasts. UL34 encodes highly related early (UL34a) and late (UL34b) proteins that are virtually identical, with the early protein ...

Concerted Formation of Macromolecular \u3cem\u3eSuppressor-mutator\u3c/em\u3e Transposition Complexes [PDF]
, 1998 Transposition of the maize Suppressor-mutator (Spm) transposon requires two element-encoded proteins, TnpA and TnpD. Although there are multiple TnpA binding sites near each element end, binding of TnpA to DNA is not cooperative, and the binding affinity

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

BMC Immunology, 2002 Background The ZAS family is composed of proteins that regulate transcription via specific gene regulatory elements. The amino-DNA binding domain (ZAS-N) and the carboxyl-DNA binding domain (ZAS-C) of a representative family member, named κB DNA binding ...

Phosphorylation of Adenovirus DNA-binding Protein
Journal of General Virology, 1989 Evidence is presented here which indicates that the adenovirus DNA-binding protein (DBP) is phosphorylated at a tyrosine residue early in infection. This was suggested by the discovery that a proportion of the label in 32P-labelled DBP was resistant to alkali, and was substantiated by acid hydrolysis of DBP immunoprecipitates and by immunoblotting with

Molecular Oncology, EarlyView.Meta‐transcriptome analysis identified FGF19 as a peptide enteroendocrine hormone associated with colorectal cancer prognosis. In vivo xenograft models showed release of FGF19 into the blood at levels that correlated with tumor volumes. Tumoral‐FGF19 altered murine liver metabolism through FGFR4, thereby reducing bile acid synthesis and increasing ...
