RNA G-quadruplexes (rG4s) are stable secondary structures formed by guanine-rich RNA sequences that have emerged as critical regulators of RNA metabolism. The rG4s are widespread in both coding and noncoding RNAs and have been implicated in regulating multiple post-transcriptional processes, including RNA stability, splicing, polyadenylation, nuclear export, localization, and translation. Recent findings reveal that rG4s play pathological roles in neurodegenerative diseases (NDs), including...

Defective nucleocytoplasmic transport (NCT) has emerged as a contributing factor in the pathogenesis of neurodegenerative diseases and aging. Valosin-containing protein (VCP) is an AAA+ATPase required for disassembly of protein complexes, and mutations in VCP cause neurodegenerative and neuromuscular diseases. We find that VCP is required for quality control of nuclear pore complexes (NPCs) by extracting selected nucleoporins from NPCs for proteasome-mediated degradation. Pathogenic VCP variants...

CONCLUSION: Our findings suggest a bidirectional relationship between MetS and EAA, with biological aging potentially mediating metabolic deterioration. EAA may serve as both a marker and mediator of metabolic health, and a promising target for prevention and intervention.

Insulin action on the skeleton is essential for bone development and whole-body energy metabolism, however a global view of signaling in this tissue is lacking. Furthermore, whether there are signaling differences that drive the gene-specific activation under insulin-resistant (IR) or ageing conditions is unknown. Here, we perform a phosphoproteomic analysis of insulin signaling in the bones of young, lean, insulin-sensitive versus old, obese, IR mice revealing a rewiring of phosphorylation. We...

Anopheles gambiae is one of the principal vectors of human malaria. Over the past two decades, transgenic mosquito strains have been essential tools for studying mosquito biology and developing genetic control strategies such as gene drives. Mosquito transformants are typically identified using fluorescent markers, which are assumed to be phenotypically neutral. While generating CRISPR-based gene drive strains carrying an OpIE2-DsRed marker we unexpectedly found that transgenic females were...

CONCLUSIONS: ε4 contributes to literacy decline among older adults, presumably due in part to the accumulation of neuropathologies associated with ε4. We discuss the potential clinical implications of ε4-related literacy decline.

CONCLUSIONS: A decision support tool for caregivers of PLwD that provides education about transitions in care site, along with support for the emotional aspects of decision making, is highly acceptable and supports caregivers' ability to engage with what can be a challenging topic.
