FIGURE 1 Identification and conservation of the axolotl endocannabinoid receptors. (A) Protein sequence alignment of the putative axolotl CB1 sequence with the rat and zebrafish CB1 sequence. (B) Protein sequence alignment of the putative axolotl <t>CB2</t> sequence with the rat and zebrafish CB2 sequence. Red asterisks and red boxes indicate amino acids that are conserved between all three species. (C) Western blot using the rat CB1 antibody on axolotl tail tissue demonstrates a single prominent band at 120 kDa (n = 3). (D) Western blot using the rat CB2 antibody on axolotl tail tissue demonstrates two bands at a similar molecular weight of 46 kDa (n = 3). MW = molecular weight (for each band in ladder). (E) Preadsorption control for the CB1 antibody using either CB1 or CB2 antigenic peptides (n = 3). (F) Preadsorption control for the CB2 antibody using CB1 or CB2 antigenic peptides (n = 3).

FIGURE 2 CB1 and CB2 are upregulated in response to tail amputation. (A) Western blot analysis demonstrates a significant upregulation of CB1 in the first 3 days after tail amputation, compared to uninjured controls (n = 3; F(4,40) = 5.994, p = .0007, one-way ANOVA). (B) No change in CB2 expression is shown in the first 3 days post tail amputation (n = 3; F(4,40) = 2.779, p = .0397, one-way ANOVA). (C) Western blot analysis demonstrates a significant upregulation of CB1 expression at both 7 and 14 days after tail amputation (n = 3; F(2,24) = 15.97, p < .0001, one-way ANOVA). (D) Western blot analysis demonstrates a significant upregulation of CB2 at 7 and 14 days post tail amputation (n = 3; F(2,24) = 10.84, p = .0004, one-way ANOVA). Uninj = uninjured tail tissue. hpa = hours post tail amputation; dpa = days post tail amputation. ns = not significant. *p < .05, **p < .01, ***p < .001, ****p < .0001 compared to uninjured controls. #p < .05.

FIGURE 4 Inhibiting CB1 and CB2 receptor signaling impairs tail regeneration. (A) Representative images of tail regenerates after a 7-day treatment with the vehicle (control, i), 1 μM AM251 (ii), or 1 μM AM630 (iii). Black dotted line indicates the original plane of amputation. Scale bar: 1 mm. (B, C) Graphs show that the proportional increase in axolotl body length was significantly reduced following either a 7-day treatment with either 1 μM AM251 (n = 8; B) or after a 7-day treatment with 1 μM AM630 (n = 8; C) compared to the vehicle control (unpaired t tests). (D) Graph shows a significant reduction in the proportional increase in axolotl body length (7 days after tail amputation) following only a 1-day pulse treatment with either 1 μM AM251 (n = 10) or 1 μM AM630 (n = 10), compared to vehicle controls (n = 10; F(2,27) = 18.86; p < .0001, one-way ANOVA). (E) Western blot analyses show that treatment with AM251 prevented the upregulation of CB1 that normally occurs in untreated or vehicle-treated control animals at 7-days post tail amputation (n = 3; Constant 7-day bath treatment: F(3,32) = 14.69; p < .0001; 1-day pulse treatment: F(3,32) = 18.60; p < .0001; one-way ANOVAs). Representative blot for 1-day pulse treatment shown. (F) Treatment with AM630 prevented the upregulation of CB2 that normally occurs in untreated or vehicle- treated control animals at 7-days post tail amputation (n = 3; constant treatment: F(3,32) = 24.80; p < .0001; 1-day pulse treatment: F(3,32) = 11.60; p < .0001; one-way ANOVAs). Representative blot for 7-day constant treatment shown. **p < .01, ***p < .001, ****p < .0001 compared to vehicle controls. ###p < .001. ####p < .0001.
