Scientific Reports, 2021 Cilia are protrusions of the cell surface and composed of hundreds of proteins many of which are evolutionary and functionally well conserved. In cells assembling motile cilia the expression of numerous ciliary components is under the control of the ...

Cargo adaptors regulate stepping and force generation of mammalian dynein-dynactin. [PDF]
, 2019 Cytoplasmic dynein is an ATP-driven motor that transports intracellular cargos along microtubules. Dynein adopts an inactive conformation when not attached to a cargo, and motility is activated when dynein assembles with dynactin and a cargo adaptor.

Dynein and intraflagellar transport [PDF]
Experimental Cell Research, 2015 Publisher Summary This chapter provides a brief background on intraflagellar transport (IFT) and reviews the studies culminating in the identification of the dynein motor that powers retrograde IFT. IFT is the active movement of multi-subunit particles along axonemal doublet microtubules in the space between the outer-doublet microtubules and the ...

Molecular Oncology, EarlyView.Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Symmetry Breaking in a Model for Nodal Cilia [PDF]
, 2005 Nodal cilia are very short cilia found in the embryonic node on the ventral surface of early mammalian embryos. They create a right to left fluid flow that is responsible for determining the normal asymmetry of the internal organs of the mammalian body ...

Intercompartmental communication in senescence
FEBS Open Bio, EarlyView.Senescent cells experience structural changes in the plasma membrane, endoplasmic reticulum, mitochondria, lysosomes, nucleus, and cytoskeleton. These alterations disrupt crosstalk among cellular compartments, impairing vesicular trafficking, contact sites, and molecular flow.

Deletion of Kif5c Does Not Alter Prion Disease Tempo or Spread in Mouse Brain
Viruses, 2021 In prion diseases, the spread of infectious prions (PrPSc) is thought to occur within nerves and across synapses of the central nervous system (CNS). However, the mechanisms by which PrPSc moves within axons and across nerve synapses remain undetermined.

Phosphoproteins associated with cyclic nucleotide stimulation of ciliary motility in Paramecium [PDF]
, 1990 Permeabilized, MgATP-reactivated cells of Paramecium (models) respond to cyclic AMP and cyclic GMP by increasing forward swimming speed. In association with the motile response, cyclic AMP and 8-bromo-cyclic GMP (8-Br-cyclic GMP) stimulated protein ...

Cold Spring Harbor Perspectives in Biology, 2016 Axonemal dyneins form the inner and outer rows of arms associated with the doublet microtubules of motile cilia. These enzymes convert the chemical energy released from adenosine triphosphate (ATP) hydrolysis into mechanical work by causing the doublets to slide with respect to each other.
