The effect of nutrient deprivation on RNA and protein synthesis in cultured Aedes albopictus mosquito cells was investigated by replacing the culture medium with phosphate-buffered saline. After a 2 h starvation treatment, incorporation of radiolabeled precursor into total RNA was inhibited by 50%,

β¦ Synopsis
Levels of RNA, mRNA and separation of ribosomal proteins from control and ethanol treated rat liver, showed no change in total RNA content, but poly(A+)mRNA was reduced significantly in ethanolic rats. Ribosomal proteins S2, S3a, S3b, S4, L3, L4, L4a, L10a and L15 were found substantially reduced in experimental rat livers. This study suggests decrease in poly(A+) mRNA coupled with loss of ribosomal proteins must be responsible for decreased protein synthesis in chronic alcoholism.

An enzyme-ribosome-mRNA complex was specifically purified by binding to the immobilized enzyme substrate and the cDNA was cloned in a single-tube reaction by one-step reverse transcription-PCR. The ganglioside GM3, used by sialyltransferase II (ST-II) as a substrate, was coated on a 96-well microtit
Our aim was to delineate the effect of glutamine on the level of heat shockinducible mRNA and synthesis of stress protein(s) in cultured kidney cells. Experiments were carried out using opossum kidney (OK) cells. The induction of HSP70 mRNA as well as the synthesis of 72,73 kDa stress proteins was e
