Gymnemic acid interacts with mammalian glycerol-3-phosphate dehydrogenase.
Article in Molecular and cellular biochemistry, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
In a previous study, we found interaction of gymnemic acid (GA) with glyceraldehyde-3-phosphate dehydrogenase (GAPDH), a key enzyme in glycolysis. We now examined interaction of GA with glycolytic and related enzymes. We found that (1) GA induced a band smearing of glycerol-3-phosphate dehydrogenase (G3PDH) as well as that of GAPDH in SDS-PAGE, (2) GA diminished the G3PDH band detected by an antibody to phosphoserine, and (3) GA inhibited the G3PDH activity. The GA-induced smearing of the G3PDH band was diminished by prior incubation of GA with gamma-cyclodextrin. GA gave no effects on the electrophoretic and phosphoserine bands of other glycolytic enzymes. NAD and NADH diminished the GA-induced smearing of the G3PDH and GAPDH bands in different concentration-dependent manner. Pretreatment of G3PDH with heated SDS-containing buffer or pretreatment with hydroxylamine diminished the GA-induced smearing of G3PDH. Deacylation of GA by alkaline hydrolysis diminished the smearing of G3PDH band, thereby indicating that the acyl moieties of GA were necessary for the GA-induced smearing of G3PDH. These results indicated the interaction of GA with G3PDH, an enzyme involved in glycerol metabolism. These studies suggest that GA may have some pharmacological activities including antidiabetic activity and lipid lowering effects via interaction with GAPDH and G3PDH.
