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

Tissue kallikrein (TK) is a serine protease synthetized in renal tubular cells located upstream from the collecting duct where renal potassium balance is regulated. Because secretion of TK is promoted by K+ intake, we hypothesized that this enzyme might regulate plasma K+ concentration ([K+]). We showed in wild-type mice that renal K+ and TK excretion increase in parallel after a single meal, representing an acute K+ load, whereas aldosterone secretion is not modified. Using aldosterone synthase-deficient mice, we confirmed that the control of TK secretion is aldosterone-independent. Mice with TK gene disruption (TK-/-) were used to assess the impact of the enzyme on plasma [K+]. A single large feeding did not lead to any significant change in plasma [K+] in TK+/+, whereas TK-/- mice became hyperkalemic. We next examined the impact of TK disruption on K+ transport in isolated cortical collecting ducts (CCDs) microperfused in vitro. We found that CCDs isolated from TK-/- mice exhibit net transepithelial K+ absorption because of abnormal activation of the colonic H+,K+-ATPase in the intercalated cells. Finally, in CCDs isolated from TK-/- mice and microperfused in vitro, the addition of TK to the perfusate but not to the peritubular bath caused a 70% inhibition of H+,K+-ATPase activity. In conclusion, we have identified the serine protease TK as a unique kalliuretic factor that protects against hyperkalemia after a dietary K+ load.
