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

Regulation of Ca(2+) entry is a key process for lymphocyte activation, cytokine synthesis and proliferation. Several members of the transient receptor potential (TRP) channel family can contribute to changes in [Ca(2+)](in); however, the properties and expression levels of these channels in human lymphocytes continue to be elusive. Here, we established and compared the expression of the most Ca(2+)-selective members of the TRPs, Ca(2+) channels transient receptor potential vanilloid 5 and 6 (TRPV5 and TRPV6), in human blood lymphocytes (HBLs) and leukemia Jurkat T cells. We found that TRPV6 and TRPV5 mRNAs are expressed in both Jurkat cells and quiescent HBLs; however, the levels of mRNAs were significantly higher in malignant cells than in quiescent lymphocytes. Western blot analysis showed TRPV5/V6 proteins in Jurkat T cells and TRPV5 protein in quiescent HBLs. However, the expression of TRPV6 protein was switched off in quiescent HBLs and turned on after mitogen stimulation of the cells with phytohemagglutinin. Inwardly directed monovalent currents that displayed characteristics of TRPV5/V6 currents were recorded in both Jurkat cells and normal HBLs. In outside-out patch-clamp studies, currents were reduced by ruthenium red, a nonspecific inhibitor of TRPV5/V6 channels. In addition, ruthenium red downregulated cell-cycle progression in both activated HBLs and Jurkat cells. Thus, we identified TRPV5 and TRPV6 calcium channels, which can be considered new candidates for Ca(2+) entry into human lymphocytes. The correlation between expression of TRPV6 channels and the proliferative status of lymphocytes suggests that TRPV6 may be involved in the physiological and/or pathological proliferation of lymphocytes.
