Ras1 activation in the posterior silk gland up-regulates ribosomal protein genes. The mRNA levels of 4 ribosomal protein genes, including mRpl1
(A), Rpl12
(B), RpS13
(C) and RpS6
(D) in the posterior silk gland from [D(+)E(+)] are 2-3-fold in comparison with those in the control silkworms [D(−)E(−)], [D(+)E(−)] and [D(−)E(+)].Three biological replicates are conducted and results from one replicate are presented. Mean ± STEDV. Five males and five females are used in each replicate. The bars labeled with different lowercase letters are significantly different (P < 0.05, ANOVA).
