Summary
This study demonstrates that ablating the m6A RNA reader YTHDF2 protects retinal ganglion cells from age-related dendrite shrinkage and vision decline in mice, identifying Hspa12a and Islr2 as key mediating targets. For lighting and healthcare applications, preserving RGC integrity in aging populations is critical for maintaining both visual function and circadian light entrainment, suggesting potential therapeutic avenues to sustain light sensitivity in older adults.
Key Findings
- Conditional ablation of Ythdf2 in mice protected RGCs from age-related dendrite shrinking and prevented associated vision loss in aged animals.
- Hspa12a and Islr2 were identified as YTHDF2 target mRNAs mediating the protective effects on RGC dendrite maintenance.
- m6A RNA modification was shown to regulate aging-related retinal degeneration, suggesting it as a novel therapeutic target for age-related vision loss.
