Background. Recent reports point to a nuclear origin of Alzheimer’s disease (AD). Aged postmitotic neurons try to repair their damaged DNA by entering the cell cycle.

Homoisoflavanone (HIF), a bioactive compound isolated from Polygonatum kingianum, selectively suppresses colorectal cancer progression by inducing DNA damage‐mediated mitochondrial apoptosis and parthanatos‐like cell death. HIF triggers mitochondrial dysfunction, including depolarized membrane potential, elevated ROS, and ATP depletion, while impairing

Mutations in the genes LMNA and BANF1 can lead to accelerated aging syndromes called progeria. The protein products of these genes, A-type lamins and BAF, respectively, are nuclear envelope (NE) proteins that interact and participate in various cellular ...

Methionine Restriction Extends Lifespan in Progeroid Mice and Alters Lipid and Bile Acid Metabolism [PDF]
C.L.-O. is supported by grants from the European Union (ERC-2016-ADG, DeAge); Ministerio de Economía y Competitividad (MINECO/FEDER: SAF2014-52413-R and SAF2017-87655-R); Instituto de Salud Carlos III (RTICC); Progeria Research Foundation (PRF2016-66 ...

This study reveals that PDZK1 loss impairs ULK1‐mediated lipophagy, driving lipid droplet accumulation and sunitinib resistance in clear cell renal cell carcinoma. PDZK1 inhibits LEF1 nuclear translocation, enhancing ULK1 transcription. Pharmacological ULK1 activation resensitizes resistant tumors to sunitinib.

Restructuring of Lamina-Associated Domains in Senescence and Cancer
Induction of cellular senescence or cancer is associated with a reshaping of the nuclear envelope and a broad reorganization of heterochromatin. At the periphery of mammalian nuclei, heterochromatin is stabilized at the nuclear lamina via lamina ...

RNA Interference by Single- and Double-stranded siRNA With a DNA Extension Containing a 3′ Nuclease-resistant Mini-hairpin Structure [PDF]
Selective gene silencing by RNA interference (RNAi) involves double-stranded small interfering RNA (ds siRNA) composed of single-stranded (ss) guide and passenger RNAs.

Dietary habits play a key role in chronic diseases, and higher annual consumption of fruit and vegetable may lower risk of dementia. Artificial intelligence predicts the lipid‐like compound α‐Amyrin (αA) from plants with edible peels as a drug candidate against Alzheimer's disease.

Lamin A/C Haploinsufficiency Modulates the Differentiation Potential of Mouse Embryonic Stem Cells [PDF]
BACKGROUND: Lamins are structural proteins that are the major determinants of nuclear architecture and play important roles in various nuclear functions including gene regulation and cell differentiation.

An absence of lamin B1 in migrating neurons causes nuclear membrane ruptures and cell death
Significance Deficiencies in lamin B1 or lamin B2 in mice result in markedly reduced neuronal density in the cerebral cortex, but the mechanism has been unclear.
