High-resolution three-dimensional views of membrane-associated clathrin and cytoskeleton in critical-point-dried macrophages. [PDF]
, 1983 We obtained high-resolution topographical information about the distribution of clathrin and cytoskeletal filaments on cytoplasmic membrane surfaces of macrophages spreading onto glass coverslips by both critical-point drying of broken-open cells and ...

Advanced Science, Volume 12, Issue 28, July 24, 2025.Different from mitosis, the female meiosis undergoes asymmetric division that produces haploid oocytes and polar body, which is essential for retaining maternal components to support subsequent fertilization and embryo development. However, the underlying mechanisms are still largely unknown.

Distribution of the cell substratum attachment (CSAT) antigen on myogenic and fibroblastic cells in culture. [PDF]
, 1985 Previous studies (Neff et al., 1982, J. Cell. Biol. 95:654-666; Decker et al., 1984. J. Cell. Biol. 99:1388-1404) have described a monoclonal antibody (CSAT Mab) directed against a complex of three integral membrane glycoproteins of 120,000-160,000 mol ...

A pharmacological cocktail for arresting actin dynamics in living cells. [PDF]
, 2011 The actin cytoskeleton is regulated by factors that influence polymer assembly, disassembly, and network rearrangement. Drugs that inhibit these events have been used to test the role of actin dynamics in a wide range of cellular processes.

Advanced Science, EarlyView.Compared with those on the pTi surface, macrophages on the TNTs surface present reduced myosin II contractility, which facilitates the nuclear translocation of the UTX. This reduction decreases the enrichment of the repressive H3K27me3 histone modification at the Abca1 gene locus, which promotes the transcription and protein expression of ABCA1 ...

Advanced Science, EarlyView.Meiosis is a specialized form of cell division that has different regulation and mechanisms with mitosis in numerous aspects. Particularly, meiosis I is unique and occurs only in germ cells to separate homologous chromosomes. Thus, determining how this unusual chromosome segregation behavior is established is central to understanding germ cell ...

Interaction of rat liver lysosomal membranes with actin. [PDF]
, 1984 Membranes were prepared from lysosomes purified 80-fold by centrifugation in a discontinuous metrizamide gradient. When salt-washed membranes were combined with rabbit muscle actin, an increase in viscosity could be measured using a falling ball ...

Defects in leaf epidermis of Arabidopsis thaliana plants with CDKA;1 activity reduced in the shoot apical meristem [PDF]
, 2012 In Arabidopsis thaliana, like in other dicots, the shoot epidermis originates from protodermis, the outermost cell layer of shoot apical meristem. We examined leaf epidermis in transgenic A.

RNA-binding protein conserved in both microtubule- and microfilament-based RNA localization [PDF]
Genes & Development, 1998 Vg1 mRNA translocation to the vegetal cortex ofXenopus oocytes requires intact microtubules, and a 3′ UTRcis-acting element (termed VLE), which also mediates sequence-specific binding of several proteins. One protein, the 69-kD Vg1 RBP, associates Vg1 RNA to microtubules in vitro.

Animal Research and One Health, EarlyView.Mechanisms of light in regulating the chick pineal clock. Abstract The circadian clock significantly impacts animal health and productivity, with light playing a crucial role in regulating circadian rhythms. However, the mechanisms behind light‐induced circadian transmission remain unclear, particularly in light‐sensitive avian species.
