      1. Selective accumulation and growth inhibition of hybrid liposomes to human hepatocellular carcinoma cells in relation to fluidity of plasma m...
        Yuji Y Komizu, Hidetsugu H Ueoka, and Ryuichi R Ueoka

        Biochem Biophys Res Commun 418(1):81-6 (2012) PMID 22240027

        Hybrid liposomes (HLs), composed of l-α-dimyristoylphosphatidylcholine (DMPC) and polyoxyethylene(23) dodecyl ether, have selectively inhibited the growth of human hepatocellular carcinoma (HCC) cells without affecting normal hepatocytes to trigger apoptosis via caspase-3 activation...
      2. The phospholipid monolayer associated with perilipin-enriched lipid droplets is a highly organized rigid membrane structure.
        Stephen M SM Storey, Avery L AL McIntosh, ... Barbara P BP Atshaves

        Am J Physiol Endocrinol Metab 301(5):E991-E1003 (2011) PMID 21846905 PMCID PMC3213997

        These results were confirmed by DPH-TMA, NBD-cholesterol, and NBD-sphingomyelin fluorescence polarization studies. By structure and organization, the perilipin-enriched LD most closely resembled the adipocyte PM. In contrast, the ADRP/TIP47-enriched LD contained a more fluid monolayer membrane, refl...

      3. Extremophilic yeasts: plasma-membrane fluidity as determinant of stress tolerance.
        Martina M Turk, Ana A Plemenitaš, and Nina N Gunde-Cimerman

        Fungal Biol 115(10):950-8 (2011) PMID 21944207

        Our aim was to investigate the response of selected yeasts and yeast-like fungi from extreme environments to various temperatures at the level of their plasma membranes, in order to elucidate the connections between their plasma-membrane fluidity (measured by electron paramagnetic resonance spectro...
      4. Interaction of carbonylcyanide p-trifluoromethoxyphenylhydrazone (FCCP) with lipid membrane systems: a biophysical approach with relevance t...
        João P Monteiro, André F Martins, ... Amália S Jurado

        J Bioenerg Biomembr 43(3):287-98 (2011) PMID 21607731

        FCCP (carbonylcyanide p-trifluoromethoxyphenylhydrazone), a classical uncoupler of mitochondrial oxidative phosphorylation, is used in this study as a model to clarify how interactions of uncouplers with membrane lipid bilayers may influence membrane biophysics and their protonophori...
      5. Interface-mediated interactions: entropic forces of curved membranes.
        Pierre P Gosselin, Hervé H Mohrbach, and Martin Michael MM Müller

        Phys Rev E Stat Nonlin Soft Matter Phys 83(5 Pt 1):051921 (2011) PMID 21728585

      6. Mechanics and dynamics of triglyceride-phospholipid model membranes: Implications for cellular properties and function.
        Kirsi I KI Pakkanen, Lars L Duelund, ... John H JH Ipsen

        ACTA-BIOENERG 1808(8):1947-56 (2011) PMID 21545789

        We provide a comprehensive discussion on the possible explanations for the observed mechanics and dynamics in the TOPOPC system and on their potential cellular implications....
      7. Acyl chain composition determines cardiolipin clustering induced by mitochondrial creatine kinase binding to monolayers
        Ofelia O Maniti, Mouhedine M Cheniour, ... Thierry T Granjon

        BBA 1808(4):11 (2011) PMID 21256109

        It has been recently shown that mitochondrial creatine kinase (mtCK) organizes mitochondrial model membrane by modulating the state and fluidity of lipids and by promoting the formation of protein-cardiolipin clusters. This report shows, using Brewster angle microscopy, that such clustering is largel...

      9. Boar semen can tolerate rapid cooling rates prior to freezing.
        Jorge D JD Juarez, Inma I Parrilla, ... Jordi J Roca

        Reprod Fertil Dev 23(5):681-90 (2011) PMID 21635817

        Two experiments were performed in the present study that demonstrated that boar spermatozoa are capable of surviving rapid cooling rates within a range of 15-5 °C before freezing. Boar ejaculates diluted in Beltsville thawing solution (BTS) (1:1, v/v) were held at 17-20 °C and shipped over a 24-h t...
      10. Cytochrome c provokes the weakening of zwitterionic membranes as measured by force spectroscopy
        Sandrine S Morandat and Karim K El Kirat

        Colloids Surf B Biointerfaces 82(1):7 (2011) PMID 20832261

        We have previously shown that besides its interaction with anionic lipids, the cyt c is also able to cross neutral lipid membranes. In this work, with the help of AFM and punch-through experiments, we have measured the force required to penetrate the membrane in the fluid and in the gel phases with...
