Origins of phase contrast in the atomic force microscope in liquids (2009)

Melcher, John, Carrasco, Carolina, Xu, Xianfan, Carrascosa, Jose L, Gomez-Herrero, Julio, Jose De Pablo, Pedro, ...

We study the physical origins of phase contrast in dynamic atomic force microscopy (dAFM) in liquids where low-stiffness microcantilever probes are often used for nanoscale imaging of soft biological...

Microglial CB2 cannabinoid receptors are neuroprotective in Huntington's disease excitotoxicity (2009)

Palazuelos, Javier, Aguado, Tania, Pazos, M. Ruth, Julien, Boris, Carrasco, Carolina, Resel, Eva, ...

Cannabinoid-derived drugs are promising agents for the development of novel neuroprotective strategies. Activation of neuronal CB1 cannabinoid receptors attenuates excitotoxic glutamatergic...

Unmasking imaging forces on soft biological samples in liquids when using dynamic atomic force microscopy: A case study on viral capsids (2008)

Xu, Xin, Carrasco, Carolina, Jose De Pablo, Pedro, Gomez-Herrero, Julio, Raman, Arvind

Dynamic atomic force microscopy is widely used for the imaging of soft biological materials in liquid environments; yet very little is known about the peak forces exerted by the oscillating probe...

Tight binding of the antitumor drug ditercalinium to quadruplex DNA (2002)

Carrasco, Carolina, Rosu, Frédéric, Gabelica, Valérie, Houssier, Claude, De Pauw, Edwin, Garbay-Jaureguiberry, Christiane, ...

The structural selectivity of the DNA-binding antitumor drug ditercalinium was investigated by competition dialysis with a series of nineteen different DNA substrates. The 7H-pyridocarbazole dimer...

DNA sequence recognition by the indolocarbazole antitumor antibiotic AT2433-B1 and its diastereoisomer (2002)

Carrasco, Carolina, Facompré, Michaël, Chisholm, John D., Van Vranken, David L., Wilson, W. David, Bailly, Christian

The antibiotic AT2433-B1 belongs to a therapeutically important class of antitumor agents. This natural product contains an indolocarbazole aglycone connected to a unique disaccharide consisting of a...

Sequence-specific minor groove binding by bis-benzimidazoles: water molecules in ligand recognition

Bailly, Christian, Chessari, Gianni, Carrasco, Carolina, Joubert, Alexandra, Mann, John, Wilson, W. David, ...

The binding of two symmetric bis-benzimidazole compounds, 2,2-bis-[4′-(3″-dimethylamino-1″-propyloxy)phenyl]-5,5-bi-1H-benzimidazole and its piperidinpropylphenyl analog, to the minor groove of...

Elastic Response, Buckling, and Instability of Microtubules under Radial Indentation

Schaap, Iwan A. T., Carrasco, Carolina, De Pablo, Pedro J., MacKintosh, Frederick C., Schmidt, Christoph F.

We tested the mechanical properties of single microtubules by lateral indentation with the tip of an atomic force microscope. Indentations up to ∼3.6 nm, i.e., 15% of the microtubule diameter,...

Manipulation of the mechanical properties of a virus by protein engineering

Carrasco, Carolina, Castellanos, Milagros, De Pablo, Pedro J., Mateu, Mauricio G.

In a previous study, we showed that the DNA molecule within a spherical virus (the minute virus of mice) plays an architectural role by anisotropically increasing the mechanical stiffness of the...
