Taurine deficiency in GES-treated mice. Plasma taurine levels were measured in control animals and in GES mice after 1 and 2 months of treatment (n = 8, SEM, P < 0.001, triple asterisks denote Mann–Whitney test) (a). Taurine concentration in retinal tissue was also reduced after 1 month of treatment (n = 8, SEM, P = 0.046, asterisk denotes Mann–Whitney test) (b)
