LepR(C357X)

---|---|
Strain ID | MT996 |
Strain Name | LepR(C357X) |
Strain Type | Mutants |
Characteristics | This mutant is a leptin receptor-defficient medaka. This knockout mutant had a point mutation of cysteine for stop codon at the 357th amino acid just before the leptin-binding domain. The evidence for loss of function of leptin-mediated signaling in the mutant is based on a lack of response to feeding in the expression of key appetite-related neuropeptides in the diencephalon. |

MT996_figure_LepRKOmedaka Food intake Quantitative analysis of food intake using Artemia nauplii as prey. A, post-juvenile fish (BWWT = 37.5±4.4 mg, BWLepRKO = 38.9±8.6 mg). B, adult fish (BWWT = 421.3±59.1 mg, BWLepRKO = 449.4±77.5 mg). *p <0.05 compared with WT medaka. Chisada et al. (2014) gives detail information on the quantitative method and post-hatched growth curves of WT and mutant medaka. |
