  1. The miR-193a-3p regulated PSEN1 gene suppresses the multi-chemoresistance of bladder cancer.

    Biochimica et Biophysica Acta 1852(3):520 (2015) PMID 25542424

    Chemoresistance prevents the curative cancer therapy, our understanding of which remains inadequate. Among the differentially expressed genes between the chemosensitive (5637) and chemoresistant (H-bc) bladder cancer cell lines, the expression level of the PSEN1 gene (presenilin 1), a key component...
  2. Mitochondrial proteolysis: its emerging roles in stress responses.

    Biochimica et Biophysica Acta 1850(2):274 (2015) PMID 25459516

    We summarize current advances in mitochondrial proteolysis-mediated stress responses. Mitochondrial proteases do not only function as surveillance systems of protein quality control by degrading unfolded proteins but also regulate mitochondrial stress responses by processing specific mitochondrial p...
  3. Role of long-chain acyl-CoA synthetase 4 in formation of polyunsaturated lipid species in hepatic stellate cells.

    Biochimica et Biophysica Acta 1851(2):220 (2015) PMID 25500141

    We previously observed that the levels of triacylglycerol (TAG) species containing long polyunsaturated fatty acids (PUFAs) are increased in in vitro activated HSCs. Here we investigated the cause and consequences of the rise in PUFA-TAGs by profiling enzymes involved in PUFA incorporation. We repor...
  4. Atomically detailed lipid bilayer models for the interpretation of small angle neutron and X-ray scattering data.

    Biochimica et Biophysica Acta 1848(2):662 (2015) PMID 25448879

    We present a new atom density profile (ADP) model and a statistical approach for extracting structural characteristics of lipid bilayers from X-ray and neutron scattering data. Models for five lipids with varying head and tail chemical composition in the fluid phase, 1,2-dioleoyl-sn-glycero-3-phosph...
  5. sAC as a model for understanding the impact of endosymbiosis on cell signaling.

    Biochimica et Biophysica Acta 1842(12 Pt B):2548 (2014) PMID 24907565

    As signaling pathways evolve, selection for new functions guides the co-option of existing material. Major transitions in the history of life, including the evolution of eukaryotes and multicellularity, exemplify this process. These transitions provided both strong selection and a plenitude of avail...
  6. Psoriasis decreases the anti-oxidation and anti-inflammation properties of high-density lipoprotein.

    Biochimica et Biophysica Acta 1841(12):1709 (2014) PMID 25240836

    We found that plasma levels of high-density lipoprotein (HDL) cholesterol were decreased in the psoriasis group compared to healthy controls. The malondialdehyde (MDA) content in plasma, in HDL3 and in low-density lipoprotein (LDL) were increased. However, the activity of plasma paraoxonase-1 (PON-1...
  7. Localization of VE-cadherin in plasmalemmal cholesterol rich microdomains and the effects of cholesterol depletion on VE-cadherin mediated c...

    Biochimica et Biophysica Acta 1841(12):1725 (2014) PMID 25281911

    We found by use of single molecule fluorescence microscopy that VE-cadherin is localised in preformed clusters when not inside adherens junctions. These clusters depend on the integrity of the actin cytoskeleton and are localised in cholesterol rich microdomains of mature endothelial cells as found...
  8. Binding of Aβ peptide creates lipid density depression in DMPC bilayer.

    Biochimica et Biophysica Acta 1838(10):2678 (2014) PMID 25037005

    We study the impact of Aβ monomer binding on the equilibrium properties of DMPC bilayer. We found that partial insertion of Aβ peptide into the bilayer reduces the density of lipids in the binding "footprint" and indents the bilayer thus creating a lipid density depression. Our simulations also reve...
  9. Transcriptional regulation of the human thromboxane A2 receptor gene by Wilms' tumor (WT)1 and hypermethylated in cancer (HIC) 1 in prostate...

    Biochimica et Biophysica Acta 1839(6):476 (2014) PMID 24747176

    The prostanoid thromboxane (TX) A(2) plays a central role in hemostasis and is increasingly implicated in neoplastic disease, including prostate and breast cancers. In humans, TXA(2) signals through the TPα and TPβ isoforms of the T prostanoid receptor, two structurally related receptors transcripti...
  10. p27 suppresses cyclooxygenase-2 expression by inhibiting p38β and p38δ-mediated CREB phosphorylation upon arsenite exposure.

    Biochimica et Biophysica Acta 1833(9):2083 (2013) PMID 23639288 PMCID PMC3686879

    We found that p27-deficiency (p27-/-) resulted in the elevation of cyclooxygenase-2 (COX-2) expression at transcriptional level, whereas the introduction of p27 brought back COX-2 expression to a level similar to that of p27+/+ cells, suggesting that p27 exhibits an inhibitory effect on COX-2 expres...
