A nucleation distance sets the cell size-dependent P-body assembly in yeast [PDF]

iScience
Summary: Cells rely on diverse intracellular structures, including phase-separated granules, to regulate biological processes. Processing bodies (P-bodies) are membraneless cytoplasmic condensates that mediate mRNA degradation and storage. Although their

Septin 9 and phosphoinositides regulate lysosome localization and their association with lipid droplets

iScience, 2022
Summary: The accumulation of lipid droplets (LDs) in the liver is a hallmark of steatosis, which is often associated with lysosomal dysfunction. Nevertheless, the underlying mechanisms remain unclear.

Constitutive activation of S1P receptors at the trans-Golgi network is required for surface transport carrier formation

iScience, 2021
Summary: The importance of the G-protein βγ subunits in the regulation of cargo transport from the trans-Golgi network (TGN) to the plasma membrane (PM) is well accepted; however, the molecular mechanism underlying the G-protein activation at the TGN ...

Myocardin-related transcription factor and serum response factor regulate cilium turnover by both transcriptional and local mechanisms

iScience, 2021
Summary: Turnover of the primary cilium (PC) is critical for proliferation and tissue homeostasis. Each key component of the PC resorption machinery, the HEF1/Aurora kinase A (AurA)/HDAC6 pathway harbors cis-elements potentially targeted by the ...

Impaired endoplasmic reticulum-mitochondrial signaling in ataxia-telangiectasia

iScience, 2021
Summary: There is evidence that ATM mutated in ataxia-telangiectasia (A-T) plays a key role in protecting against mitochondrial dysfunction, the mechanism for which remains unresolved.

Rab33b-exocyst interaction mediates localized secretion for focal adhesion turnover and cell migration

iScience, 2022
Summary: Rab proteins are well known regulators of intracellular trafficking; however, more and more studies point to their function also in other cellular processes, including cell migration.

Looking outside the box: a comparative cross-kingdom view on the cell biology of the three major lineages of eukaryotic multicellular life

Cellular and Molecular Life Sciences, 2023
Many cell biological facts that can be found in dedicated scientific textbooks are based on findings originally made in humans and/or other mammals, including respective tissue culture systems.

Identification of embryonic RNA granules that act as sites of mRNA translation after changing their physical properties

iScience, 2022
Summary: Fertilized eggs begin to translate mRNAs at appropriate times and placements to control development, but how the translation is regulated remains unclear.

Regulation and functions of cell division in the intestinal tissue.

Seminars in Cell and Developmental Biology, 2023
In multicellular organisms, epithelial cells are key elements of tissue organization. In developing epithelial tissues, cellular proliferation and differentiation are under the tight regulation of morphogenetic programs to ensure correct organ formation ...

Temporal and spatial dynamics of immune cells in spontaneous liver transplant tolerance

iScience, 2023
Summary: The liver has long been deemed a tolerogenic organ. We employed high-dimensional mass cytometry and immunohistochemistry to depict the temporal and spatial dynamics of immune cells in the spleen and liver in a murine model of spontaneous liver ...
