The vacuolar proton-ATPase plays a major role in several membrane-bounded organelles in Paramecium [PDF]
, 2005 The vacuolar proton-ATPase (V-ATPase) is a multisubunit enzyme complex that is able to transfer protons over membranes against an electrochemical potential under ATP hydrolysis. The enzyme consists of two subcomplexes: V0, which is membrane embedded; and

Cytoplasmic streaming in plant cells: the role of wall slip [PDF]
J. R. Soc. Interface 2012 9, 1398-1408, 2012 We present a computer simulation study, via lattice Boltzmann simulations, of a microscopic model for cytoplasmic streaming in algal cells such as those of Chara corallina. We modelled myosin motors tracking along actin lanes as spheres undergoing directed motion along fixed lines.

Plant, Cell &Environment, Volume 48, Issue 6, Page 3939-3954, June 2025.ABSTRACT Calcium (Ca2+)‐dependent signalling plays a well‐characterised role in the perception and response mechanisms to environmental stimuli in plant cells. In the context of a constantly changing environment, it is fundamental to understand how crop yield and microalgal biomass productivity are affected by external factors. Ca2+ signalling is known

Polarity patterns of stress fibers [PDF]
Phys. Rev. Lett. 105, 238103 (2010), 2010 Stress fibers are contractile actomyosin bundles commonly observed in the cytoskeleton of metazoan cells. The spatial profile of the polarity of actin filaments inside contractile actomyosin bundles is either monotonic (graded) or periodic (alternating).

Systemic aging fuels heart failure: Molecular mechanisms and therapeutic avenues
ESC Heart Failure, Volume 12, Issue 2, Page 1059-1080, April 2025.Abstract Systemic aging influences various physiological processes and contributes to structural and functional decline in cardiac tissue. These alterations include an increased incidence of left ventricular hypertrophy, a decline in left ventricular diastolic function, left atrial dilation, atrial fibrillation, myocardial fibrosis and cardiac ...

Nramp1 and NrampB Contribute to Resistance against Francisella in Dictyostelium
Frontiers in Cellular and Infection Microbiology, 2017 The Francisella genus comprises highly pathogenic bacteria that can cause fatal disease in their vertebrate and invertebrate hosts including humans. In general, Francisella growth depends on iron availability, hence, iron homeostasis must be tightly ...

Functional analysis of the clathrin assembly protein, AP180, in Dictyostelium discoideum [PDF]
, 2006 textAP180, an important coat component of clathrin-coated vesicles, is known to assemble clathrin triskelia into cages of uniform size. To gain insight into the relationship between AP180 and clathrin, the gene that encodes AP180 in Dictyostelium ...

The Nramp (SLC11) proteins regulate development, resistance to pathogenic bacteria and iron homeostasis in Dictyostelium discoideum [PDF]
, 2013 Summary The Dictyostelium discoideum genome harbors two genes encoding members of the Nramp superfamily, which is conserved from bacteria (MntH proteins) to humans (Slc11 proteins).

Journal of Cachexia, Sarcopenia and Muscle, Volume 16, Issue 2, April 2025.Abstract Background Cachexia is a severe form of muscle wasting disorder particularly observed in patients with advanced cancer. The absence of effective strategies to ameliorate cachexia indicates our poor understanding of the mechanisms of cachexia. By employing system‐wide approaches, we investigated molecular mechanisms underlying cancer secreted ...
