Double-Stranded RNA and TGF-α Promote MUC5AC Induction in Respiratory Cells

Poliovirus single-stranded RNA and double-stranded RNA: differential infectivity in enucleate cells.

The ability of poliovirus virion RNA and double-stranded RNA (replicative form) to replicate in enucleate mouse L cells was investigated. Virion RNA replicated successfully in the absence of the cell nucleus, whereas replicative form infection did not produce any detectable progeny in enucleate cells. The results provide direct evidence of a nuclear requirement early in the infection initiated ...

double-stranded rna viral infection in tehran trichomonas vaginalis isolates.

background : trichomonas vaginalis is a pathogenic protozoon and may be contaminated with dsrna virus called trichomonas vaginalis virus (tvv). the viral infection is an important factor for its patho-genesis and sensitivity to metronidazole. the presence of tvv is associated with qualitative and quantitative expression of cysteine proteinases and surface immunogenic; p270. the purpose of this ...

Double-stranded regions in heterogeneous nuclear RNA from Hela cells.

Heterogeneous nuclear RNA from HeLa cells contains double-stranded regions that arise by base pairing of complementary sequences that exist as parts of the same molecule (intramolecular base pairing). When denatured, the RNA sequences that form the double-stranded regions hybridize rapidly to HeLa cell DNA, suggesting that they are transcribed from reiterated sites in the genome. The messenger ...

DHX15 senses double-stranded RNA in myeloid dendritic cells.

Many members of the DEXD/H box helicase family play important roles in the innate immune system against viral infection. Therefore, we isolated dsRNA complex in myeloid dendritic cells. We found that DHx15, a DEXDc helicase family member, is one of the components of this complex. Knockdown of DHX15 expression by short hairpin RNA efficiently reduced the ability of myeloid dendritic cells to pro...
