1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Synthetic 21-bp-long short interfering RNAs (siRNA) can stimulate sequence-specific mRNA degradation in mammalian cell cultures, a process referred to as RNA interference (RNAi). In the present study, the potential of RNAi was compared to the traditional antisense approach, acting mainly via RnaseH, for targeting the recombinant rat pain-related cation-channel P2X3 expressed in CHO-K1 and a rat brain tumour-derived cell line, 33B. Downregulation of the P2X3 receptor was evaluated at the mRNA, protein, and functional levels. In this study, four siRNA duplexes induced up to 95% sequence-specific inhibition of the P2X3 mRNA, independent of the type of 2 nt 3'-overhang modification and the location of the targeted sequences. Furthermore, we detected and characterised an independent combinatorial effect of antisense oligonucleotides (ASOs) and RNAi-mediated specific inhibition of the P2X3 receptor. Enhanced downregulation was observed only when siRNA was combined with nonhomologous ASO, targeting distant regions on the common P2X3 mRNA. The two reagents resulted in more efficient downregulation of P2X3 mRNA when administered in combination rather than separately. To our knowledge, this is the first investigation at the molecular level of the potential benefits of mixed antisense and RNAi-mediated treatment for inhibiting expression of a medically relevant pain-related gene.
