This study identifies VRK-1 as a regulator of chromatin-nuclear lamina interactions in C. elegans, showing its role in stress-induced chromatin reorganization and survival.

The paper shows that nuclear pore density regulates LAD formation during C. elegans embryogenesis, with heterochromatic LADs providing UV protection.

The paper shows that inactivating the NMD pathway suppresses the embryonic lethality of gsr-1 mutants in C. elegans by enabling the transsulfuration pathway to compensate for the loss of glutathione reductase function.

A whole genome multiparametric CRISPR screen in progeria identifies new pathways that can reverse cellular aging phenotypes by targeting protein translation and related processes.

The paper identifies an interkinetic envelope surrounding chromosomes in C. elegans oocytes during interkinesis, showing it is a distinct structure from the nuclear envelope.

This paper introduces a C. elegans model of progeria by mutating baf-1 to mimic the human NGPS mutation, showing accelerated aging and altered gene expression.

The paper identifies tissue-specific chromatin binding patterns of HPL-1 and HPL-2 in C. elegans, revealing their distinct roles in gene regulation and heterochromatin maintenance.

The paper expands the FLP toolkit in C. elegans by adding new driver lines and a protein degradation system, enabling precise gene inactivation and transcriptomic profiling.

This study shows that loss of glutathione redox homeostasis impairs proteostasis by inhibiting autophagy-dependent protein degradation in C. elegans and other organisms.

The paper develops a method to analyze essential genes in C. elegans by combining flow cytometry and high-throughput image analysis to sort and study homozygous lethal mutants.

The paper develops an FLP-based toolkit for precise spatiotemporal control of gene expression in C. elegans, achieving high recombination efficiency in specific tissues.
