Summary of animal research focusing on galanin system and RNA methylation.

No.	Strain	Sex	Age	Physical Activity	Stress Model	Main Outcome	Reference
1	C57BL/6J	male and female	3–6 weeks	running wheels	foot shock	increased galanin expression in noradrenergic neurons	[129]
2	C57BL/6	male	5–7 weeks	treadmill	restraint stress	improved brain RNA m6A methylation	[139]
3	Sprague–Dawley	male	7 weeks	voluntary wheel running	foot shock	increased galanin levels in the LC	[127]

LC—locus coeruleus.
