SHH and microphthalmia: In zebrafish, cannabinoid‐induced microphthalmia can be rescued with Shh mRNA injections or by treatment with CB1R antagonists, (Fish et al., 2019) while another study found that Shh mRNA injection prevented behavioral and locomotor alterations caused by inhibition of FAAH and MAGL (Boa‐Amponsem et al., 2019).
