A 36-base hairpin within lncRNA , modulated by alternative splicing, interacts with the IKKα coiled-coil domain and inhibits NF-κB and tumor cell phenotypes.

The 1.7 kb DRAIC long noncoding RNA inhibits tumor growth, inhibits cancer cell invasion, migration, colony formation and interacts with IKK (IκB kinase) subunits, inhibiting the phosphorylation and degradation of the NF-κB inhibitor, IκB, to suppress the activation of NF-κB. Whether these activities are all linked is unclear.

Structural determinants of inverted Alu-mediated backsplicing revealed by -MaP and -JuMP.

Biogenesis of circular RNA usually involves a backsplicing reaction where the downstream donor site is ligated to the upstream acceptor site by the spliceosome. For this reaction to occur, it is hypothesized that these sites must be in proximity. Inverted repeat sequences, such as Alu elements, in the upstream and downstream introns are predicted to base-pair and represent one mechanism for inducing proximity.

Draft genome sequences of six high pH adapted strains isolated from Mariana forearc serpentinite mud volcanoes.

Six marine bacterial isolates were obtained from fluid and sediments collected at alkaline serpentinite mud volcanoes of the Mariana forearc to examine life at high pH in a marine environment. Here, we present the draft genome sequences of these six isolates, classified as strains of the species .

Protein binding in an mRNA 5'-UTR sterically hinders translation.

Structures in the 5' untranslated regions (UTRs) of mRNAs can physically modulate translation efficiency by impeding the scanning ribosome or by sequestering the translational start site. We assessed the impact of stable protein binding in 5'- and 3'-UTRs on translation efficiency by targeting the MS2 coat protein to a reporter RNA via its hairpin recognition site. Translation was assessed from the reporter RNA when co-expressed with MS2 coat proteins of varying affinities for the RNA, and at different expression levels.
