Identical measles viral mRNA species were present in similar amounts in the persistently infected cell lines LU106, HEpPi and MaSSPE, and in lytically infected cells as determined from Northern blots. The attenuation of transcription with the gene order did not vary significantly between different infected systems. A previously described selective restriction of F protein production in Lu106 cells could not be explained by defective transcription of F mRNA. RNA synthesis also continued unimpeded at restrictive temperatures for the temperature-sensitive viruses in Lu106 and HEpPi cells. Northern blotting revealed a prominent band in HEpPi RNA and a weak band in Lu106 RNA with the characteristics of incomplete genomes. In all infected cells, previously unrecognized small RNA species, hybridizing with the F- and H-specific probes, were discovered.

UI	MeSH Term	Description	Entries
D008459	Measles virus	The type species of MORBILLIVIRUS and the cause of the highly infectious human disease MEASLES, which affects mostly children.	Edmonston virus
D008970	Molecular Weight	The sum of the weight of all the atoms in a molecule.	Molecular Weights,Weight, Molecular,Weights, Molecular
D009693	Nucleic Acid Hybridization	Widely used technique which exploits the ability of complementary sequences in single-stranded DNAs or RNAs to pair with each other to form a double helix. Hybridization can take place between two complimentary DNA sequences, between a single-stranded DNA and a complementary RNA, or between two RNA sequences. The technique is used to detect and isolate specific sequences, measure homology, or define other characteristics of one or both strands.
