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

1. We have investigated the possible role of A-kinase anchoring proteins (AKAPs) in protein kinase A (PKA) signalling to ATP-sensitive K+ (K(ATP)) channels of rat isolated mesenteric arterial smooth muscle cells using whole-cell patch clamp and peptides that inhibit PKA-AKAP binding. 2. Intracellular Ht31 peptide (20 microM), which inhibits the PKA-AKAP interaction, blocked K(ATP) current activation by either dibutyryl cAMP or calcitonin gene-related peptide. Ht31-proline (20 microM), which does not inhibit PKA binding to AKAP, did not block K(ATP) current activation. 3. Ht31 reduced K(ATP) current activated by pinacidil and also prevented its inhibition by Rp-cAMPS, effects consistent with Ht31 blocking steady-state K(ATP) channel activation by PKA. However, Ht31 did not prevent K(ATP) current activation by the catalytic subunit of PKA. 4. An antibody to the RII subunit of PKA showed localization of PKA near to the cell membrane. Our results provide evidence that both steady-state and receptor-driven activation of K(ATP) channels by PKA involve the localization of PKA by an AKAP.
