We explored the feasibility of a strategy based on transposons to generate identified mutants of most Caenorhabditis elegans genes. A total of 1088 random new insertions of C. elegans transposons Tc1, Tc3, and Tc5 were identified by anchored PCR, some of which result in a mutant phenotype.

Growing evidence suggests that plant compounds are emerging as a tremendous source for slowing the onset and progression of Alzheimer's disease (AD). Ursonic acid (UNA) is a naturally occurring pentacyclic triterpenoid with some hypoglycemic, anticancer, and antiinflammatory activities. However, the pharmacological effects of UNA on AD are still unknown.

The target of rapamycin complex mTORC1 has key roles in cell growth and metabolism and its inhibition delays ageing. Recent work by Ogawa et al. in Caenorhabditis elegans argues that modulation of pre-mRNA splicing factors and alternative splicing are key mediators of mTORC1 signalling and can enhance longevity.

Ergothioneine (ET), a dietary thione/thiol, is receiving growing attention for its possible benefits in healthy aging and metabolic resilience. Our study investigates ET's effects on healthspan in aged animals, revealing lifespan extension and enhanced mobility in Caenorhabditis elegans, accompanied by improved stress resistance and reduced age-associated biomarkers. In aged rats, ET administration enhances exercise endurance, muscle mass, and vascularization, concomitant with higher NAD levels in muscle.

During meiosis, pairing between homologous chromosomes is stabilized by the assembly of the synaptonemal complex (SC). The SC ensures the formation of crossovers between homologous chromosomes and regulates their distribution. However, how the SC regulates crossover formation remains elusive.

The ability to manipulate gene activity and control transgene expression is essential to study gene function. While several genetic tools for modifying genes or controlling expression separately are available for Caenorhabditis elegans, there are no genetic approaches to generate mutations that simultaneously disrupt gene function and provide genetic access to the cells expressing the disrupted gene. To achieve this, we developed a versatile gene trap strategy based on cGAL, a GAL4-UAS bipartite expression system for C.
