  1. Coordinate regulation of microenvironmental stimuli and role of methylation in bone metastasis from breast carcinoma.

    Biochimica et Biophysica Acta 1863(1):64 (2016) PMID 26481505

    The pathogenesis of bone metastasis is unclear, and much focus in metastatic biology and therapy relays on epigenetic alterations. Since DNA-methyltransferase blockade with 5-aza-2'-deoxycytidine (dAza) counteracts tumour growth, here we utilized dAza to clarify whether molecular events undergoi...
  2. Characterization of the cell-free DNA released by cultured cancer cells.

    Biochimica et Biophysica Acta 1863(1):157 (2016) PMID 26529550

    The most prominent factor that delays the translation of cell-free DNA (cfDNA) analyses to clinical practice is the lack of knowledge regarding its origin and composition. The elucidation of the former is complicated by the seemingly random fluctuation of quantitative and qualitative characteris...
  3. FoxO1 mediates TGF-beta1-dependent cardiac myofibroblast differentiation.

    Biochimica et Biophysica Acta 1863(1):128 (2016) PMID 26518453

    Cardiac fibroblast differentiation to myofibroblast is a crucial process in the development of cardiac fibrosis and is tightly dependent on transforming growth factor beta-1 (TGF-β1). The transcription factor forkhead box O1 (FoxO1) regulates many cell functions, including cell death by apoptosi...
  4. Structural and biochemical characterization of two heme binding sites on α1-microglobulin using site directed mutagenesis and molecular simulation.

    Biochimica et Biophysica Acta 1864(1):29 (2016) PMID 26497278

    α1-Microglobulin (A1M) is a reductase and radical scavenger involved in physiological protection against oxidative damage. These functions were previously shown to be dependent upon cysteinyl-, C34, and lysyl side-chains, K(92, 118,130). A1M binds heme and the crystal structure suggests that C34...
  5. Subcellular functions of proteins under fluorescence single-cell microscopy.

    Biochimica et Biophysica Acta 1864(1):77 (2016) PMID 26025769

    A cell is a highly organized, dynamic, and intricate biological entity orchestrated by a myriad of proteins and their self-assemblies. Because a protein's actions depend on its coordination in both space and time, our curiosity about protein functions has extended from the test tube into the int...
  6. Measuring specificity in multi-substrate/product systems as a tool to investigate selectivity in vivo.

    Biochimica et Biophysica Acta 1864(1):70 (2016) PMID 26321598

    Multiple substrate enzymes present a particular challenge when it comes to understanding their activity in a complex system. Although a single target may be easy to model, it does not always present an accurate representation of what that enzyme will do in the presence of multiple substrates sim...
  7. Transient protein-protein interactions visualized by solution NMR.

    Biochimica et Biophysica Acta 1864(1):115 (2016) PMID 25896389

    Proteins interact with each other to establish their identities in cell. The affinities for the interactions span more than ten orders of magnitude, and KD values in μM-mM regimen are considered transient and are important in cell signaling. Solution NMR including diamagnetic and paramagnetic te...
  8. In situ and real time investigation of the evolution of a Pseudomonas fluorescens nascent biofilm in the presence of an antimicrobial peptide.

    Biochimica et Biophysica Acta 1858(1):75 (2016) PMID 26525662

    Against the increase of bacterial resistance to traditional antibiotics, antimicrobial peptides (AMP) are considered as promising alternatives. Bacterial biofilms are more resistant to antibiotics that their planktonic counterpart. The purpose of this study was to investigate the action of an AM...
  9. Phosphorylation and isoform use in p120-catenin during development and tumorigenesis.

    Biochimica et Biophysica Acta 1863(1):102 (2016) PMID 26477567 PMCID PMC4658284

    P120-catenin is essential to vertebrate development, modulating cadherin and small-GTPase functions, and growing evidence points also to roles in the nucleus. A complexity in addressing p120-catenin's functions is its many isoforms, including optional splicing events, alternative points of trans...
  10. Phase diagram of a polyunsaturated lipid mixture: Brain sphingomyelin/1-stearoyl-2-docosahexaenoyl-sn-glycero-3-phosphocholine/cholesterol.

    Biochimica et Biophysica Acta 1858(1):153 (2016) PMID 26525664 PMCID PMC4664456

    Phospholipids having a polyunsaturated acyl chain are abundant in biological membranes, but their behavior in lipid mixtures is difficult to study. Here we elucidate the nature of such mixtures with this report of the first ternary phase diagram containing the polyunsaturated lipid SDPC in mixtu...
