Background: In humans GRB10 negatively regulates GH and IGF1 signaling predominantly via altering phosphorylation of PI3K/mTOR/AKT and MEK/ERK pathways which relate to both growth and metabolic function. We have previously shown that Grb10 knockdown in Zebrafish results in overgrowth with an increase in length and head size. However the impact on weight in relation to length has not been assessed.Objective: To develop a model t...
