title: Ribosome metabolism during the vitellogenic cycle of the mosquito, Aedes aegypti.
abstract: Ribosome accumulation and synthesis in the fat body of the mosquito Aedes aegypti increased by approx. 4-fold during 18 h after the blood meal, consistent with the pattern of total RNA accumulation during the synthetic phase of the vitellogenic cycle. By 24-30 h after the blood meal, the accumulated ribosomes began to be degraded, and the total RNA content in the fat body eventually returned to previtellogenic levels. A method has been developed for isolation of ribosomal subunits from fat body, and the ribosomal proteins have been shown to have properties similar to those from cultured Aedes albopictus cells by two-dimensional polyacrylamide gel electrophoresis. Proteins S1, S10, and A from the small ribosomal subunit are phosphorylated when fat body is incubated in Aedes saline in the presence of [32P]orthophosphate.
