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

Despite the recognized role of bradykinin (BK)-induced calcium and chloride conductance in regulating salt transport in the kidney, the signaling pathway involved has not been well examined. Patch clamp of murine proximal tubule (TKPTS) cells revealed that BK (10 nM) produced an increase in an outwardly rectifying current from a basal level of 2.9 +/- 0.6 to 13.8 +/- 1.1 pA/pF following addition of BK (n = 8; p < 0.001). The shift in reversal potential seen with BK on changing the intracellular solution to 152 mM chloride and significant inhibition of the current by 100 microM 4,4'-di-isothiocyanato-stilbene-2,2'-disulphonic acid (DIDS) suggested that BK activated a chloride current. BK-induced current was blocked by B2 receptor antagonist but not by B1 antagonist or pertussis toxin indicating that the current was mediated by B2 receptors possibly through Gq activation. TMB-8 completely blocked the BK-calcium rise in fura-2 studies but did not block the BK-chloride response indicating that BK-mediated chloride current is calcium-independent. BK-induced current was dependent on phospholipase C (PLC) since U73122, a PLC-beta blocker (10 microM) blocked it completely. Furthermore, chloride conductance was not modulated by bisindolylmaleimide, an inhibitor of protein kinase C (PKC), but was enhanced by dibutyryl cAMP. We conclude that BK-induced rise in chloride current is mediated by B2 receptors and dependent on PLC activation but not dependent on calcium rise. Furthermore, the current can be modulated by cAMP but not PKC.
