Knockdown of klotho Leads to Cell Movement Impairment during Zebrafish Gastrulation

Fishes, 2023
(1) Background: Klotho is a multifunctional protein, but its biophysiological roles during fish early development are unclear. (2) Methods: We carried out anti-sense Klotho morpholino injection and whole-mount in situ hybridization experiments in this ...

Statistical inference of the mechanisms driving collective cell movement [PDF]

, 2017
Numerous biological processes, many impacting on human health, rely on collective cell movement. We develop nine candidate models, based on advection-diffusion partial differential equations, to describe various alternative mechanisms that may drive ...

Optimal cellular mobility for synchronization arising from the gradual recovery of intercellular interactions [PDF]

, 2012
Cell movement and intercellular signaling occur simultaneously during the development of tissues, but little is known about how movement affects signaling.

Paracrine signalling of AGR2 stimulates RhoA function in fibroblasts and modulates cell elongation and migration

Cell Adhesion & Migration, 2019
The most prominent cancer-associated fibroblasts (CAFs) in tumor stroma is known to form a protective structure to support tumor growth. Anterior gradient-2 (AGR2), a tumor secretory protein is believed to play a pivotal role during tumor ...

Sulfated carboxymethyl cellulose and carboxymethyl κ-carrageenan immobilization on 3D-printed poly-ε-caprolactone scaffolds differentially promote pre-osteoblast proliferation and osteogenic activity

Frontiers in Bioengineering and Biotechnology, 2022
The lack of bioactivity in three-dimensional (3D)-printing of poly-є-caprolactone (PCL) scaffolds limits cell-material interactions in bone tissue engineering.

Functional Analysis of Spontaneous Cell Movement under Different Physiological Conditions [PDF]

, 2008
Cells can show not only spontaneous movement but also tactic responses to environmental signals. Since the former can be regarded as the basis to realize the latter, playing essential roles in various cellular functions, it is important to investigate ...

Modelling cell movement and chemotaxis pseudopod based feedback [PDF]

, 2011
A computational framework is presented for the simulation of eukaryotic cell migration and chemotaxis. An empirical pattern formation model, based on a system of non-linear reaction-diffusion equations, is approximated on an evolving cell boundary using ...

MOVEMENT OF A SESSILE CELL COLONY

Mathematical Proceedings of the Royal Irish Academy, 2012
Surface motion of an isolated sessile bacterial colony is described by a free surface condition known as the kinematic boundary condition. When t he colony is attached to a surface which does not allow slip, a difficulty arises in describing the motion of the contact line at the boundary of the colony.

Effects of brefeldin A on the localization of Tobamovirus movement protein and cell-to-cell movement of the virus

Virology, 2007
It has been demonstrated that the subcellular location of Tobamovirus movement protein (MP) which was fused with green fluorescent protein (MP:GFP) changed during the infection process. However, the intracellular route through which MP is transported and its biological meaning are still obscure.

Leptin affects filopodia and cofilin in NK-92 cells in a dose- and time-dependent manner

European Journal of Histochemistry, 2018
Hyperleptinemia, associated with obesity, is related with immune dysfunction and carcinogenesis. Natural Killer (NK) cells, a major component of the innate immune system are mediators of anti-tumor immunity and the most actively migrating cells among ...
