Functional Integration of Ecological Networks through Pathway Proliferation [PDF]
Journal of Theoretical Biology 245: 98-111, 2006 Large-scale structural patterns commonly occur in network models of complex systems including a skewed node degree distribution and small-world topology. These patterns suggest common organizational constraints and similar functional consequences. Here, we investigate a structural pattern termed pathway proliferation.

Unbounded autocatalytic growth on diffusive substrate: the extinction transition [PDF]
, 2006 The effect of diffusively correlated spatial fluctuations on the proliferation-extinction transition of autocatalytic agents is investigated numerically. Reactants adaptation to spatio-temporal active regions is shown to lead to proliferation even if the mean field rate equations predict extinction, in agreement with previous theoretical predictions ...

Probabilistic approach to a proliferation and migration dichotomy in the tumor cell invasion [PDF]
, 2007 The proliferation and migration dichotomy of the tumor cell invasion is examined within a two-component continuous time random walk (CTRW) model. The balance equations for the cancer cells of two phenotypes with random switching between cell proliferation and migration are derived. The transport of tumor cells is formulated in terms of the CTRW with an

Migration and proliferation dichotomy in tumor cell invasion [PDF]
, 2006 We propose a two-component reaction-transport model for the migration-proliferation dichotomy in the spreading of tumor cells. By using a continuous time random walk (CTRW) we formulate a system of the balance equations for the cancer cells of two phenotypes with random switching between cell proliferation and migration.

To proliferate or not to proliferate [PDF]
Cardiovascular Research, 2010 This editorial refers to ‘Cardiomyocyte cell cycle control and growth estimation in vivo —an analysis based on cardiomyocyte nuclei’ by S. Walsh et al ., pp. 365–373, this issue. Cardiomyocytes in mammalian hearts undergo significant reduction in their cell proliferation capacity soon after birth, which is not disputed.

Nature Communications, 2023 As one of the major components of plant cell walls, cellulose is crucial for plant growth and development. Cellulose is synthesized by cellulose synthase (CesA) complexes (CSCs), which are trafficked and delivered from the Golgi apparatus to the plasma ...

BMC Cancer, 2019 Background S100A8 and S100A9, two heterodimer-forming members of the S100 family, aberrantly express in a variety of cancer types. However, little is known about the mechanism that regulates S100A8/S100A9 co-expression in cancer cells.

Pmp27 Promotes Peroxisomal Proliferation [PDF]
, 1995 Peroxisomes perform many essential functions in eukaryotic cells. The weight of evidence indicates that these organelles divide by budding from preexisting peroxisomes. This process is not understood at the molecular level.

Non-Proliferation and Counter-Proliferation [PDF]
, 2018 European approaches to the proliferation of nuclear, biological, and chemical weapons—the so-called weapons of mass destruction (WMD)—have undergone a profound transformation during the last few decades. This chapter will trace the varying European policy responses to WMD proliferation over time and examine how European security doctrines have evolved ...
