Mitochondrial Factors in the Cell Nucleus. [PDF]

Int J Mol Sci, 2023
The origin of eukaryotic organisms involved the integration of mitochondria into the ancestor cell, with a massive gene transfer from the original proteobacterium to the host nucleus. Thus, mitochondrial performance relies on a mosaic of nuclear gene products from a variety of genomes.

Limited Proteolysis-Coupled Mass Spectrometry Identifies Phosphatidylinositol 4,5-Bisphosphate Effectors in Human Nuclear Proteome

Cells, 2021
Specific nuclear sub-compartments that are regions of fundamental processes such as gene expression or DNA repair, contain phosphoinositides (PIPs). PIPs thus potentially represent signals for the localization of specific proteins into different nuclear ...

Cell Nucleus in Context [PDF]

Critical Reviews™ in Eukaryotic Gene Expression, 2000
The molecular pathways that participate in regulation of gene expression are being progressively unraveled. Extracellular signals, including the binding of extracellular matrix and soluble molecules to cell membrane receptors, activate specific signal transducers that process information inside the cell leading to alteration in gene expression. Some of

Quantitative super-resolution microscopy reveals the differences in the nanoscale distribution of nuclear phosphatidylinositol 4,5-bisphosphate in human healthy skin and skin warts

Frontiers in Cell and Developmental Biology, 2023
Introduction: Imaging of human clinical formalin-fixed paraffin-embedded (FFPE) tissue sections provides insights into healthy and diseased states and therefore represents a valuable resource for basic research, as well as for diagnostic and clinical ...

Tailoring Cellular Function: The Contribution of the Nucleus in Mechanotransduction

Frontiers in Bioengineering and Biotechnology, 2021
Cells sense a variety of different mechanochemical stimuli and promptly react to such signals by reshaping their morphology and adapting their structural organization and tensional state.

Super-Resolution Localisation of Nuclear PI(4)P and Identification of Its Interacting Proteome

Cells, 2020
Phosphoinositides are glycerol-based phospholipids, and they play essential roles in cellular signalling, membrane and cytoskeletal dynamics, cell movement, and the modulation of ion channels and transporters.

Analysis of the extranucleolar ribonucleoprotein particles of Cycas revoluta Thunb. (Cycadaceae) and Ceratozamia mexicana Brongn. (Zamiaceae)

Botan‪ical Sciences, 2022
Background: Nuclear ribonucleoprotein particles play a key role in RNA processing and in the gene expression pathway. Interchromatin granules (GICs) involved in the metabolism of pre-messenger RNA (pre-mRNA) were described in Allium cepa and ...

Nuclear Phosphoinositides—Versatile Regulators of Genome Functions

Cells, 2019
The many functions of phosphoinositides in cytosolic signaling were extensively studied; however, their activities in the cell nucleus are much less clear.

Immunocytochemical localization of chromatin regions UV-microirradiated in S phase or anaphase : Evidence for a territorial organization of chromosomes during cell cycle of cultured Chinese hamster cells [PDF]

, 1983
Chinese hamster cells (M3-1 line) in S phase were laser-UV-microirradiated (λ, 257 nm) at a small site of the nucleus. Cells were fixed either immediately thereafter or in subsequent stages of the cell cycle, including prophase and metaphase.
