Analysis of total protein and polysome assembly in WT and kri1lcas002 embryos. (A-C) Total protein was extracted from lysates of deyolked whole embryos (n>20) and then measured by BCA (bicinchoninic acid) protein assay. The protein synthesis was impaired at 3 dpf (p=0.0003), 4 dpf (p<0.0001) and 5 dpf (p<0.0001). Error bars represent standard error of the mean (SEM). ***, P≤0.001 (Student t test). (D) Representative polysome fractionation analysis performed on WT and kri1lcas002 embryos at 3 dpf demonstrates reduced levels of 40 S ribosomal subunits, 80 S monosomes and polysomes; and excessive 60 S subunits in kri1lcas002 larvae compared to that in WT.
