Gastric mucous cells of rats subjected to water-immersion stress were incubated with [3H]-palmitic acid and [14C]-N-acetylgalactosamine. The peptidyl-tRNA released by gastric polysomes was precipitated with cold ethanol and then the content was determined. A 70% reduction in the peptidyl-tRNA isolated was observed in the stressed rats, as compared with in control rats. The peptide recovered from the peptidyl-tRNA showed 30-50% less [3H]-palmitic acid and [14C]-N-acetylgalactosamine incorporation in the stressed rats than in normal controls. It was thus suggested that translation, acylation and glycosylation of the peptides in the ribosomes of the gastric mucosa were remarkably affected by the stress.

D005753 Gastric Mucosa Lining of the STOMACH, consisting of an inner EPITHELIUM, a middle LAMINA PROPRIA, and an outer MUSCULARIS MUCOSAE. The surface cells produce MUCUS that protects the stomach from attack by digestive acid and enzymes. When the epithelium invaginates into the LAMINA PROPRIA at various region of the stomach (CARDIA; GASTRIC FUNDUS; and PYLORUS), different tubular gastric glands are formed. These glands consist of cells that secrete mucus, enzymes, HYDROCHLORIC ACID, or hormones.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D012343 RNA, Transfer The small RNA molecules, 73-80 nucleotides long, that function during translation (TRANSLATION, GENETIC) to align AMINO ACIDS at the RIBOSOMES in a sequence determined by the mRNA (RNA, MESSENGER). There are about 30 different transfer RNAs. Each recognizes a specific CODON set on the mRNA through its own ANTICODON and as aminoacyl tRNAs (RNA, TRANSFER, AMINO ACYL), each carries a specific amino acid to the ribosome to add to the elongating peptide chains.

D012346 RNA, Transfer, Amino Acyl Intermediates in protein biosynthesis. The compounds are formed from amino acids, ATP and transfer RNA, a reaction catalyzed by aminoacyl tRNA synthetase. They are key compounds in the genetic translation process.
