TABLE 3.

Statistical analysis of Cnr1 and Cnr2 expression level in different biological samples (equine brain, skin, keratinocytes, and fibroblasts)

Gene	Biological Material				Kruskal‐Wallis ANOVA
	Brain	Skin	Keratinocytes	Fibroblasts
	Relative gene expression (2−ΔCT ± SD)
Cnr1	1.96E−02 ± 1.53E−03	1.14E−04 ± 4.17E−05	1.09E−04 ± 1.06E−05	5.40E−05 ± 3.06E−05	P = .007*
Cnr2	1.16E−02 ± 3.11E−03	5.75E−04 ± 1.96E−04	3.25E−04 ± 1.16E−04	1.52E−04 ± 1.40E−04	P = .0005*

Note: Data are presented as the mean value of 2^−ΔCT ± SD; P‐value <0.05 was considered statistically significant and marked with asterisk (*).
