Energy efficiency of information transmission by electrically coupled neurons
, 2012 The generation of spikes by neurons is energetically a costly process. This paper studies the consumption of energy and the information entropy in the signalling activity of a model neuron both when it is supposed isolated and when it is coupled to ...

Multiple ETS family transcription factors bind mutant p53 via distinct interaction regions
FEBS Letters, EarlyView.Mutant p53 gain‐of‐function is thought to be mediated by interaction with other transcription factors. We identify multiple ETS transcription factors that can bind mutant p53 and found that this interaction can be promoted by a PXXPP motif. ETS proteins that strongly bound mutant p53 were upregulated in ovarian cancer compared to ETS proteins that ...

Extracellular cysteine in connexins: Role as redox sensors [PDF]
, 2016 Indexación: Scopus.Connexin-based channels comprise hemichannels and gap junction channels. The opening of hemichannels allow for the flux of ions and molecules from the extracellular space into the cell and vice versa.

Connexin 43 connexon to gap junction transition is regulated by zonula occludens-1
Molecular Biology of the Cell, 2011 Cx43 gap junctions (GJs) are integral to the function of the mammalian heart. It is shown that ZO-1 dynamically regulates the transition between Cx43 connexons and GJ intercellular channels, determining the balance of connexon-mediated cell permeability ...

The newfound relationship between extrachromosomal DNAs and excised signal circles
FEBS Letters, EarlyView.Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Gap acceptance and Driver behavior at intersections in Minna, North Central Nigeria
Nigerian Journal of Technological Development, 2010 The headways, spacing distributions and gap acceptance were measured from two main intersections in Minna, Central Nigeria/The average critical gap and spacing for stadium junction are 2.39 seconds and 11.08m respectively, and that of Mustapha hospital ...

Electron optics with ballistic graphene junctions
, 2016 Electrons transmitted across a ballistic semiconductor junction undergo refraction, analogous to light rays across an optical boundary. A pn junction theoretically provides the equivalent of a negative index medium, enabling novel electron optics such as

Gap Junctions in Development [PDF]
American Zoologist, 1986 The concept of a multicellular organism as an assemblage of cells that work together harmoniously for the good of the whole organism is well established. Over the past 15 years, however, it has become increasingly clear that the individual cells of multicellular animals are not as self-sufficient and independent of each other as once had been believed.
