β-actin shows limited mobility and is required only for supraphysiological insulin-stimulated glucose transport in young adult soleus muscle
(American Physiological Society, 2018)
© 2018 American Physiological Society. All rights reserved. Studies in skeletal muscle cell cultures suggest that the cortical actin cytoskeleton is a major requirement for insulin-stimulated glucose transport, implicating ...
The actin filament network associated to Sertoli cell ectoplasmic specializations
(Instituto de Histología y Embriología, 2011-12)
Junctional devices in Sertoli cells conform the blood-testis barrier and play a key role in maturation and differentiation of germ cells. The spacial distribution of ectoplasmic specializations of Sertoli cells was studied ...
Identities among actin-encoding cDNAs of the Nile tilapia (Oreochromis niloticus) and other eukaryote species revealed by nucleotide and amino acid sequence analyses
(2008-01-01)
Actin-encoding cDNAs of Nile tilapia (Oreochromis niloticus) were isolated by RT-PCR using total RNA samples of different tissues and further characterized by nucleotide sequencing and in silico amino acid (aa) sequence ...
Actin levels fluctuate in the seminiferous epithelium at various stages during spermatogenesis in the rat
(Instituto de Histología y Embriología de Mendoza "Dr. Mario H. Burgos", 2017-12)
The testis is a double gland comprised of the sperm-producing seminiferous tubules and a complex endocrine interstice. The former structures generate and release whole cells (exocrine aspect of the gland) while the latter ...
Mechanotransduction-dependent changes in the contributions of actin isoforms to the auditory stereocilia cytoskeleton
(Universidad EIAIngeniería BiomédicaEscuela de Ciencias de la VidaEnvigado (Antioquia, Colombia), 2021)
ABSTRACT: Stereocilia, mechanosensitive projections on top of the inner ear hair cells, are made of filaments from both cytoplasmatic actin isoforms: β and γ- (Furness et al., 2005; Perrin et al., 2010). The absence of ...
Ulipristal acetate interferes with actin remodeling induced by 17β-estradiol and progesterone in human endometrial stromal cells
(Frontiers Research Foundation, 2018-06)
Ulipristal acetate (UPA) is a selective progesterone receptor modulator (SPRM) used for emergency contraception and for the medical management of symptomatic uterine fibroids (UF). Treatment with UPA turns in amenorrhea ...
Neuroprotective effects of hypothermia on synaptic actin cytoskeletal changes induced by perinatal asphyxia
(Elsevier Science, 2014-05)
Cerebral hypoxia–ischemia damages synaptic proteins, resulting in cytoskeletal alterations, protein aggregation and neuronal death. In the previous works, we have shown neuronal and synaptic changes in rat neostriatum ...
Isolation of galectin-1 from human platelets: its interaction with actin
(Springer, 2012-01)
Galectins are a family of animal lectins defined by their β-galactoside-binding specificity and a consensus sequence in their carbohydrate-recognition domain. Galectin-1 (Gal-1) is expressed as a non-covalently linked ...
Extracellular Galectin-3 Induces Accelerated Oligodendroglial Differentiation Through Changes in Signaling Pathways and Cytoskeleton Dynamics
(Humana Press, 2019-01)
Galectin-3 (Gal-3) is a chimeric protein structurally composed of unusual tandem repeats of proline and short glycine-rich segments fused onto a carbohydrate recognition domain. Our studies have previously demonstrated ...
