Protein kinase Cη is targeted to lipid droplets.
Article in Histochemistry and cell biology, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Protein kinase C (PKC) is a family of kinases that regulate numerous cellular functions. They are classified into three subfamilies, i.e., conventional PKCs, novel PKCs, and atypical PKCs, that have different domain structures. Generally, PKCs exist as a soluble protein in the cytosol in resting cells and they are recruited to target membranes upon stimulation. In the present study, we found that PKCη tagged with EGFP distributed in lipid droplets (LD) and induced a significant reduction in LD size. Two other novel PKCs, PKCδ and PKCε, also showed some concentration around LDs, but it was less distinct and less frequent than that of PKCη. Conventional and atypical PKCs (α, βII, γ, and ζ) did not show any preferential distribution around LDs. 1,2-Diacylglycerol, which can activate novel PKCs without an increase of Ca(2+) concentration, is the immediate precursor of triacylglycerol and exists in LDs. The present results suggest that PKCη modifies lipid metabolism by phosphorylating unidentified targets in LDs.
