Sex-specific modulation of nigrostriatal degeneration and cortical glutamatergic plasticity in a mouse model of Parkinsonism

This study reveals that in a mouse model of Parkinsonism, males exhibit greater nigrostriatal degeneration while females display distinct motor cortical glutamatergic remodeling characterized by reduced VGLUT2 expression, highlighting critical sex-specific differences in disease mechanisms and potential therapeutic targets.

Isoliensinine Sensitizes Gastric Cancer Cells to FDX1-Mediated Cuproptosis by Targeting Mitochondria

This study demonstrates that isoliensinine inhibits gastric cancer progression by inducing mitochondrial apoptosis and G1-phase cell cycle arrest, while synergizing with cuproptosis inducers through FDX1 targeting to amplify DLAT aggregation and oxidative stress, offering a promising combinatorial therapeutic strategy.

Emergence of novel begomovirus species through recombination in chilli leaf curl disease epidemics in southern India

This study identifies two novel begomovirus species, Chilli leaf curl Dindigul virus and Chilli leaf curl Karur virus, alongside established strains, as the causative agents of severe chilli leaf curl disease epidemics in southern India, revealing extensive recombination events and strong purifying selection that drive the rapid evolution of these viral complexes.

Grassland species loss over the past decade in a highly fragmented landscape with an extinction debt

A resurvey of grassland plant communities in a fragmented Japanese landscape over a decade reveals that significant species loss and community disassembly are driven by both recent habitat destruction and historical landscape changes persisting as an extinction debt, with these lagged effects varying by spatial scale and plant functional group, underscoring the need for proactive restoration alongside habitat conservation.

In vivo base editing rescues hearing in humanized MPZL2 mice within a structure-dependent therapeutic window

This study demonstrates that in vivo base editing can effectively rescue hearing in a humanized mouse model of DFNB111 even after cochlear maturation, provided that Deiters' cell architecture remains intact, thereby establishing structural integrity rather than chronological age as the critical determinant of the therapeutic window.
