Expression of proliferation-dependent antigens during cellular ageing of normal and progeroid human fibroblasts [PDF]

, 1994
Normal human fibroblasts display a limited lifespan in culture, which is due to a steadily decreasing fraction of cells that are able to proliferate.

p53-sensitive epileptic behavior and inflammation in Ft1 hypomorphic mice [PDF]

, 2018
Epilepsy is a complex clinical condition characterized by repeated spontaneous seizures. Seizures have been linked to multiple drivers including DNA damage accumulation.

PSMA8‐Containing 20S Proteasome Regulates Spermiogenesis and Male Fertility

Advanced Science, EarlyView.
PSMA8 assembles s20S proteasome that degrades specific substrates in elongating spermatids. Degradation of s20S‐substrates activates translation of FXR1‐target mRNAs, which are essential for mitochondrial sheath formation and sperm morphogenesis.

Mice with reduced expression of the telomere-associated protein Ft1 develop p53-sensitive progeroid traits [PDF]

, 2018
Human AKTIP and mouse Ft1 are orthologous ubiquitin E2 variant proteins involved in telomere maintenance and DNA replication. AKTIP also interacts with A- and B-type lamins.

First Generation Proteolysis Targeting Chimeras (PROTACs) for the Treatment of Progeria

Advanced Science, EarlyView.
We report the first PROTACs designed to degrade progerin, introducing a novel therapeutic approach for progeria. The best compound, UCM‐18142, significantly reduces progerin levels and improves key disease phenotypes in patient‐derived cells and in the LmnaG609G/G609G mouse model, paving the way for new treatment strategies targeting the root cause of ...

Lamin chromatin binding is modulated by interactions of different LAP2α domains with lamins and chromatin

iScience
Summary: Lamins A and C are components of the lamina at the nuclear periphery and associate with heterochromatin. A distinct, relatively mobile pool of lamin A/C in the nuclear interior associates with euchromatic regions and with lamin-associated ...

Dose‐Dependent Reprogramming of Chromatin Accessibility by SOX4 Drives the Transcriptional Response to Iron Overload

Advanced Science, EarlyView.
This study demonstrates that iron overload triggers widespread chromatin compaction and transcriptional repression in human granulosa cells, recapitulating features of endometriosis. The epigenetic reprogramming is orchestrated by a TFEB‐SOX4‐SWI/SNF axis, with SOX4 acting as a central, dosage‐sensitive regulator.

Roles of Cross-Membrane Transport and Signaling in the Maintenance of Cellular Homeostasis [PDF]

, 2016
Organelles allow specialized functions within cells to be localized, contained and independently regulated. This separation is oftentimes achieved by selectively permeable membranes, which enable control of molecular transport, signaling between ...

Nuclear Actin and Lamins in Viral Infections

Viruses, 2012
Lamins are the best characterized cytoskeletal components of the cell nucleus that help to maintain the nuclear shape and participate in diverse nuclear processes including replication or transcription.

MG53 Coordinates Macrophage Polarization and Neuroimmune Coupling to Promote Corneal Nerve Regeneration via the MPEG1–MVP–STAT6 Axis

Advanced Science, EarlyView.
Corneal nerve regeneration is critical to corneal wound healing processes. The current study reveals a novel role of MG53 in promoting corneal nerve regeneration after alkali induced injury. Mechanistically, MG53 enters macrophages via its receptor, MPEG1, promotes MVP K63 ubiquitination, and triggers STAT6 induced repair‐related genes expression ...
