  1. 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...
  2. Dipeptidyl peptidase 9 subcellular localization and a role in cell adhesion involving focal adhesion kinase and paxillin.

    Biochimica et Biophysica Acta 1853(2):470 (2015) PMID 25486458

    We investigated the intracellular distribution of DPP9 chimeric fluorescent proteins and consequent functions of DPP9. We showed that while some DPP9 is associated with mitochondria, the strongest co-localization was with microtubules. Under steady state conditions, DPP9 was not seen at the plasma m...
  3. 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...
  4. STAT6 silencing up-regulates cholesterol synthesis via miR-197/FOXJ2 axis and induces ER stress-mediated apoptosis in lung cancer cells.

    Biochimica et Biophysica Acta 1849(1):32 (2015) PMID 25451482

    We have shown an inverse relationship of STAT6 and cholesterol biosynthesis and also identified FOXJ2 binding sites in the upstream region of 3 key genes (HMGCR, HMGCS1 and IDI1) of the cholesterol synthesis pathway. Our previous study also provided clues toward the anti-apoptotic role played by STA...
  5. Mechanism of dopachrome tautomerization into 5,6-dihydroxyindole-2-carboxylic acid catalyzed by Cu(II) based on quantum chemical calculation...

    Biochimica et Biophysica Acta 1850(2):281 (2015) PMID 25450182

    We propose the reaction mechanism of the tautomerization to DHICA by Cu(II) from density functional theory-based calculation. We clarified that the activation barriers of α-deprotonation, β-deprotonation, and decarboxylation from dopachrome are significantly reduced by coordination of Cu(II) to quin...
  6. Transcription factor networks regulating hepatic fatty acid metabolism.

    Biochimica et Biophysica Acta 1851(1):2 (2015) PMID 24814048

    We will review the main transcriptional mechanisms regulating the expression of genes involved in hepatic lipid metabolism. The principal regulatory pathways are composed of simple modules of transcription factor crosstalks, which correspond to building blocks of more complex regulatory networks. Th...
  7. 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...
  8. 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...
  9. 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...
  10. Salinomycin induces activation of autophagy, mitophagy and affects mitochondrial polarity: differences between primary and cancer cells.

    Biochimica et Biophysica Acta 1833(9):2057 (2013) PMID 23639289

    We show a massive autophagic response to Salinomycin (substantially stronger than to commonly used autophagic inducer Rapamycin) in prostrate-, breast cancer cells, and to lesser degree in human normal dermal fibroblasts. Interestingly, autophagy induced by Salinomycin is a cell protective mechanism...
