Fig 5. Relative mRNA expression levels of digestive enzymes and nutrient transporters in glass eel.

The mRNA expression levels were presented as mean ± SD (n = 6). (A) For the digestive enzymes, the mRNA expression level of pepsinogen (pep) was approximately six times higher than that of α-amylase (amy), and four times higher than that of triglyceride lipase (lip). (B) For the nutrient transporters, the mRNA expression level of large neutral amino acids transporter small subunit 2 (slc7a8) was approximately four point five times higher than that of sodium/glucose co-transporter member 1 (sglt1), and five times higher than that of Niemann-Pick C1-like 1 (npc1l1). Means with the same letter were not significantly different at the 5% level, as determined by Tukey’s HSD test.
