title: [Low molecular weight nuclear RNA of human gastric adenocarcinoma].
abstract: Low molecular weight nuclear RNAs (LMWN RNAs) isolated by thermal phenol fractionation from malignant tumor of the stomach and the mucous membrane of patients with gastric ulcer have been studied. There were found some differences in the relative content of U1 and U2 nucleoplasmic fractions as well as of loosely bound to a nucleolus U3 fraction of LMWN RNAs. The changes observed resemble those obtained earlier for experimental animal tumors.
