Three-dimensional architecture of actin filaments in Listeria monocytogenes comet tails. [PDF]
Proc Natl Acad Sci U S A, 2013 The intracellular bacterial pathogen Listeria monocytogenes is capable of remodelling the actin cytoskeleton of its host cells such that "comet tails" are assembled powering its movement within cells and enabling cell-to-cell spread.

Investigating the Composition of Listeria actin Comet Tails [PDF]
, 2022 Several intracellular bacterial pathogens, including Listeria monocytogenes (Lm), can colonizethe cytosol of host cells during infection. Cytosolic Lm then hijacks the host cells’ actin polymerization machinery using ActA to recruit the host Arp2/3 ...

Palladin Compensates for the Arp2/3 Complex and Supports Actin Structures during
mBio, 2018 Palladin is an important component of motile actin-rich structures and nucleates branched actin filament arrays in vitro. Here we examine the role of palladin during Listeria monocytogenes infections in order to tease out novel functions of palladin.

Assessing the genotoxicity of oral titanium dioxide nanoparticle administration in male rats using micronuclei and comet assay [PDF]
Fayoum Journal of Agricultural Research and Development, 2023 This study evaluated the toxic effects of titanium dioxide (TiO2) nanoparticles (NPs) on rats that received oral administration of TiO2-NPs with a particle size of 15±2nm once daily at doses of 0, 50, 100, 150, 200, and 300mg/kg for ten weeks.

Nature, 1870 IN NATURE of 16th December, Prof. Tait advances the opinion that the tail of a comet consists of nothing but meteorites; mentioning in proof of this that the orbits of the August and November meteors have been determined, and found to be identical with those of two known comets. I do not question the importance of this most remarkable fact, but I think

Stochastic modeling for the COMET-assay [PDF]
, 2003 We present a stochastic model for single cell gel electrophoresis (COMET-assay) data. Essential is the use of point process structures, renewal theory and reduction to intensity histograms for further data ...

Frontiers in Genetics, 2015 In the alkaline comet assay, cells are embedded in agarose, lysed, and then subjected to further processing including electrophoresis at high pH (>13). We observed very large variations of mean comet tail lengths of cell samples from the same population ...

Actin filament attachments for sustained motility in vitro are maintained by filament bundling. [PDF]
PLoS ONE, 2012 We reconstructed cellular motility in vitro from individual proteins to investigate how actin filaments are organized at the leading edge. Using total internal reflection fluorescence microscopy of actin filaments, we tested how profilin, Arp2/3, and ...
