Cellular morphological changes occur during cell life and diseases, such as senescence and cancer. Although the cellular conditions should be varied with the morphology changes, there have been no attempts to understand the cellular morphological changes by focusing on the intracellular molecular environment and elucidating the behaviour of nucleic acids. Nucleic acids can form hierarchical secondary and higher-order structures due to intermolecular interactions and other factors. Additionally,...

Ribosomal DNA (rDNA) encodes the 18S, 5.8S, and 28S rRNA, accounting for ∼70% of cellular transcription. Despite its essential role and links to cancer and aging, quantifying rDNA instability in mammals remains challenging due to its repetitive organization and inherent heterogeneity. Here, we developed a murine rDNA FISH probe and genomic tools tailored for laboratory mouse strains. The results confirmed rDNA cluster locations, revealed substantial inter- and intra-strain as well as...

Cancer cells precisely modulate replication stress to sustain genomic instability without triggering lethal DNA damage, yet regulators enabling this delicate balance remain largely unknown. Here, we identify N-methyl-D-aspartate receptor synaptonuclear signaling and neuronal migration factor (NSMF) as a novel and critical regulator of replication stress in colorectal cancer (CRC). NSMF expression is significantly elevated in CRC tissues and correlates closely with elevated replication stress. In...

Aging is accompanied by profound changes in energy metabolism, yet the underlying drivers and modulators of these shifts remain incompletely understood. Here, we investigated how life-history evolution shapes metabolic aging and pharmacological responsiveness by leveraging Drosophila melanogaster lines divergently selected for reproductive timing. We measured organismal oxygen consumption rate and performed untargeted metabolomics in young and old flies of both sexes from long-lived "O" lines...

Immune cells from the skull marrow reach the meninges through bone channels. In this issue of Immunity, Eme-Scolan and colleagues show that these channels form neonatally and can be remodeled to alter immune access to the brain's borders. Their work suggests that the skull is a developmental checkpoint for neuroimmune defense, potentially shaping vulnerability or resilience across the lifespan.

Dual-task walking, performing a secondary task while walking, challenges attentional and motor resources and has been linked to increased fall risk. While cognitive dual tasks are most often studied, physical (e.g., load carriage) and "combination" tasks such as obstacle crossing may also impact gait. Whole-body angular momentum and its variability provide sensitive markers of locomotor stability. We investigated how dual-task type influences gait mechanics and stability in younger and older...

CONCLUSIONS: These findings highlight PAQR4 as a potential biomarker and a candidate molecule of interest for osteosarcopenia.
