Evaluation of loop formation dynamics in a chromatin fiber during chromosome condensation
Hiroshi Yokota, Masashi Tachikawa
Chromatin fibers composed of DNA and proteins fold into consecutive loops to form rod-shaped chromosome in mitosis. Although the loop growth dynamics is investigated in several stu…
Modeling membrane morphological change during autophagosome formation
Yuji Sakai, Ikuko Koyama-Honda, Masashi Tachikawa +2
Autophagy is an intracellular degradation process that is mediated by de novo formation of autophagosomes. Autophagosome formation involves dynamic morphological changes; a disk-sh…
Dynamical Pattern Selection of Growing Cellular Mosaic in Fish Retina
Noriaki Ogawa, Tetsuo Hatsuda, Atsushi Mochizuki +1
A Markovian lattice model for photoreceptor cells is introduced to describe the growth of mosaic patterns on fish retina. The radial stripe pattern observed in wild-type zebrafish…
A mathematical model for period-memorizing behavior in Physarum plasmodium
Masashi Tachikawa
A mathematical model to describe period-memorizing behavior in Physarum plasmodium are reported. In constructing the model, we first examine the basic characteristics required for…
Regular and irregular modulation of frequencies in limit cycle oscillator networks
Masashi Tachikawa
Frequency modulation by perturbation is the essential trait that differentiates limit cycle oscillators from phase oscillators. We studied networks of identical limit cycle oscilla…
Fluctuation induces evolutionary branching in a modeled microbial ecosystem
Masashi Tachikawa
The impact of environmental fluctuation on species diversity is studied with a model of the evolutionary ecology of microorganisms. We show that environmental fluctuation induces e…
