title: Small nuclear RNAs synthesis in PHA-stimulated and nonstimulated human peripheral blood lymphocytes.
abstract: Five fractions of small nuclear RNAs (snRNAs) were identified in nuclei of human peripheral blood lymphocytes. They have been designated as: H, G', D, C and A (nomenclature according to Weinberg) in order to decreasing electrophoretic mobility. Their synthesis was observed from the first day of treatment with mitogen and was continued with different intensity during four days of culture. In nonstimulated lymphocytes exclusively A and G' fractions were detected but no (14C)-uridine incorporation was observed.
