STIM1 regulates store-operated Ca2+ entry in oocytes.
Article in Developmental biology, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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.
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
The single transmembrane-spanning Ca(2+)-binding protein, STIM1, has been proposed to function as a Ca(2+) sensor that links the endoplasmic reticulum to the activation of store-operated Ca(2+) channels. In this study, the presence, subcellular localization and function of STIM1 in store-operated Ca(2+) entry in oocytes was investigated using the pig as a model. Cloning and sequence analysis revealed the presence of porcine STIM1 with a coding sequence of 2058 bp. In oocytes with full cytoplasmic Ca(2+) stores, STIM1 was localized predominantly in the inner cytoplasm as indicated by immunocytochemistry or overexpression of human STIM1 conjugated to the yellow fluorescent protein. Depletion of the Ca(2+) stores was associated with redistribution of STIM1 along the plasma membrane. Increasing STIM1 expression resulted in enhanced Ca(2+) influx after store depletion and subsequent Ca(2+) add-back; the influx was inhibited when the oocytes were pretreated with lanthanum, a specific inhibitor of store-operated Ca(2+) channels. When STIM1 expression was suppressed using siRNAs, there was no change in cytosolic free Ca(2+) levels in the store-depleted oocytes after Ca(2+) add-back. The findings suggest that in oocytes, STIM1 serves as a sensor of Ca(2+) store content that after store depletion moves to the plasma membrane to stimulate store-operated Ca(2+) entry.
