  1. 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...
  2. 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...
  3. 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...
  4. 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...
  5. 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...
  6. Regulation of SGLT expression and localization through Epac/PKA-dependent caveolin-1 and F-actin activation in renal proximal tubule cells.

    Biochimica et Biophysica Acta (BBA) - Bioenerge... 1823(4):971 (2012) PMID 22230192

    This study demonstrated that exchange proteins directly activated by cAMP (Epac) and protein kinase A (PKA) by 8-bromoadenosine (8-Br)-adenosine 3',5'-cyclic monophosphate (cAMP) stimulated [(14)C]-α-methyl-D-glucopyranoside (α-MG) uptake through increased sodium-glucose cotranspor...
  7. Proteasomal AAA-ATPases: structure and function.

    Biochimica et Biophysica Acta (BBA) - Bioenerge... 1823(1):67 (2012) PMID 21820014

    The 26S proteasome is a chambered protease in which the majority of selective cellular protein degradation takes place. Throughout evolution, access of protein substrates to chambered proteases is restricted and depends on AAA-ATPases. Mechanical force generated through cycles of ATP binding and hydr...
  8. Plastoquinol is more active than α-tocopherol in singlet oxygen scavenging during high light stress of Chlamydomonas reinhardtii.

    Biochimica et Biophysica Acta (BBA) - Bioenerge... 1817(3):389 (2012) PMID 22192719

    We have performed comparative analysis of different prenyllipids in Chlamydomonas reinhardtii cultures during high light stress under variety of conditions (presence of inhibitors, an uncoupler, heavy water). The obtained results indicate that plastoquinol is more active than α-tocopherol in scaven...
  9. Is an orthorhombic lateral packing and a proper lamellar organization important for the skin barrier function?

    Biochimica et Biophysica Acta (BBA) - Bioenerge... 1808(6):1529 (2011) PMID 21036143

    We examined the effect of the orthorhombic to hexagonal phase transition on the barrier function of human SC and SCS. In addition, the SCS was modified by changing the free fatty acid composition, resulting in a hexagonal packing and perturbed lamellar organization. By measuring the permeability to...
  10. Energy transfer in an LH4-like light harvesting complex from the aerobic purple photosynthetic bacterium Roseobacter denitrificans.

    Biochimica et Biophysica Acta (BBA) - Bioenerge... 1807(5):518 (2011) PMID 21419098

    A peripheral light-harvesting complex from the aerobic purple bacterium Roseobacter (R.) denitrificans was purified and its photophysical properties characterized. The complex contains two types of pigments, bacteriochlorophyll (BChl) a and the carotenoid (Car) spheroidenone and possesses unique spec...
