The role of PDLIM1, a PDZ-LIM domain protein, at the ribbon synapses in the chicken retina
(Wiley-liss, div John Wiley & Sons Inc., 2020-07)
PDLIM's protein family is involved in the rearrangement of the actin cytoskeleton. In the present study, we describe the localization of PDLIM1 in chicken photoreceptors. This study provides evidence that this protein is ...
Transition to superdiffusive behavior in intracellular actin-based transport mediated by molecular motors
(American Physical Society, 2009-12)
Intracellular transport of large cargoes, such as organelles, vesicles, or large proteins, is a complex dynamical process that involves the interplay of adenosine triphosphate-consuming molecular motors, cytoskeleton ...
Glycolytic oscillations and intracellular K+ concentration are strongly coupled in the yeast Saccharomyces cerevisiae
(Elsevier Science Inc., 2020-03)
We measured temporal oscillations of intracellular K+ concentration in yeast cells exhibiting glycolytic oscillations using fluorescence spectroscopy and microscopy methods. These oscillations showed the same period as ...
Cell-centred model for the simulation of curved cellular monolayers
(Springer International Publishing, 2015-12)
This paper presents a cell-centred model for the simulation of planar and curved multicellular soft tissues. We propose a computational model that includes stress relaxation due to cell reorganisation (intercellular ...
Biological actions of the hsp90-binding immunophilins FKBP51 and FKBP52
(Multidisciplinary Digital Publishing Institute, 2019-08)
Immunophilins are a family of proteins whose signature domain is the peptidylprolylisomerase domain. High molecular weight immunophilins are characterized by the additional presence of tetratricopeptide-repeats (TPR) through ...
Nuclear expression of NHERF1/EBP50 in Clear Cell Renal Cell Carcinoma
(Elsevier Gmbh, 2021-07)
The Na/H exchange regulatory factor 1 or Ezrin-radixin-moesin-binding phosphoprotein 50 (NHERF1/EBP50) is an adaptor protein implicated in the stabilization of molecular complexes linking extracellular signals with the ...
Peritubular myoid cells from rat seminiferous tubules contain actin and myosin filaments distributed in two independent layers
(Society for the Study of Reproduction, 2012-05)
In the mammalian testis, peritubular myoid cells (PM cells) surround the seminiferous tubules (STs), express cytoskeletal markers of true smooth muscle cells, and participate in the contraction of the ST. It has been claimed ...
Intracellular motor driven transport of rodlike smooth organelles along microtubules
(American Physical Society, 2020-06-19)
Molecular motors are fascinating proteins that use the energy of ATP hydrolysis to drive vesicles and organelles along cytoskeleton filaments toward their final destination within the cell. Several copies of these proteins ...
Insulin receptor signaling regulates actin cytoskeletal organization in developing photoreceptors
(Wiley Blackwell Publishing, Inc, 2009-09-10)
The insulin receptor (ir) and ir signaling proteins are widely distributed throughout the cns. ir signaling provides a trophic signal for transformed retinal neurons in culture and we recently reported that deletion of ir ...
Coupled response of membrane hydration with oscillating metabolism in live cells: An alternative way to modulate structural aspects of biological membranes?
(MDPI AG, 2019-11)
We propose that active metabolic processes may regulate structural changes in biological membranes via the physical state of cell water. This proposition is based on recent results obtained from our group in yeast cells ...
