Research summary

This study investigates the role of apelin, an adipokine, in modulating emotional behaviors in mice, considering age and metabolic state. Utilizing apelin Knockout (Apelin⁻/⁻) mice, researchers observed that 12-month-old Apelin⁻/⁻ mice exhibited an antidepressant-like phenotype under standard diet conditions. Conversely, 6-month-old Apelin⁻/⁻ mice on a high-fat diet displayed increased anxiety-like behaviors and peripheral insulin resistance. Treatment with metformin reversed the anxious phenotype without affecting insulin resistance, suggesting a complex interplay between apelin signaling, metabolic state, and emotional behavior.

Key outcome of the study

Apelin deficiency leads to age- and metabolic state-dependent alterations in emotional behaviors, with implications for understanding mood disorders and metabolic diseases.

Model

Apelin Knockout (Apelin⁻/⁻) mice generated to study the effects of apelin deficiency on emotional behavior across different ages and metabolic states.
