hsromega lncRNAs in conditionally modulating the important Ras signaling pathway during R7 differentiation.
Title: Altered levels of hsromega lncRNAs further enhance Ras signaling during ectopically activated Ras induced R7 differentiation in Drosophila.
In order to obtain a clearer understanding of the role of hsromega in FUS toxicity, we herein drove the expression of human FUS in Drosophila eyes with and without a hsromega RNAi background. We found that hFUS was largely soluble and also able to form aggregates. As such, hFUS was toxic, inducing an aberrant eye morphology with the loss of pigmentation
Title: FUS toxicity is rescued by the modulation of lncRNA hsrω expression in Drosophila melanogaster.
The results suggest that the heat-shock-induced hsp70 transcripts are not destabilized by hsromega-RNAi transgene expression.
Title: Expression of hsrω-RNAi transgene prior to heat shock specifically compromises accumulation of heat shock-induced Hsp70 in Drosophila melanogaster.
variation at a polymorphic 8 bp-indel site in the heat shock hsr-omega gene that maps to the right arm of chromosome 3
Title: Thermal tolerance trade-offs associated with the right arm of chromosome 3 and marked by the hsr-omega gene in Drosophila melanogaster.
Transposon insertion in the promoter causes male sterility in insertion homozygotes.
Title: Male sterility associated with overexpression of the noncoding hsromega gene in cyst cells of testis of Drosophila melanogaster.
Significant latitudinal patterns in hsr-omega transcript level detected for both heat stimulated and non-heat stimulated flies
Title: Latitudinal clines in heat tolerance, protein synthesis rate and transcript level of a candidate gene in Drosophila melanogaster.
Hsromega-n transcripts are essential for thermotolerance and remobilization of hnRNPs, HP1 and RNA polymerase II during recovery from heat shock.
Title: The large noncoding hsrω-n transcripts are essential for thermotolerance and remobilization of hnRNPs, HP1 and RNA polymerase II during recovery from heat shock in Drosophila.
Pleiotropic consequences of misexpression of the developmentally active and stress-inducible non-coding hsr omega gene in Drosophila
Title: Pleiotropic consequences of misexpression of the developmentally active and stress-inducible non-coding hsrω gene in Drosophila.
An important function of hsr-omega is the modulation of general protein synthesis.
Title: Transcripts from the Drosophila heat-shock gene hsr-omega influence rates of protein synthesis but hardly affect resistance to heat knockdown.
direct and indirect interactions of the hsromega transcripts with a variety of regulatory proteins like hnRNPs, CBP, proteasome, Drosophila inhibitor of apoptosis protein 1 (DIAP1)
Title: Improved activities of CREB binding protein, heterogeneous nuclear ribonucleoproteins and proteasome following downregulation of noncoding hsromega transcripts help suppress poly(Q) pathogenesis in fly models.
