Prostaglandin F2 alpha-stimulated phospholipase D activation in osteoblast-like MC3T3-E1 cells: involvement in sustained 1,2-diacylglycerol production.
Article in The Biochemical journal, 1994. 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 [3H]myristic acid-labelled osteoblast-like MC3T3-E1 cells, prostaglandin F2 alpha (PGF2 alpha)-induced PLD activity was assessed by measuring the [3H]phosphatidylethanol (PEt) formation in the presence of ethanol. Inhibition of the increase in intracellular Ca2+ concentration ([Ca2+]i) by U73122, an inhibitor of phosphoinositide-specific phospholipase C (PI-PLC), or chelation of extracellular Ca2+ with EGTA or of intracellular Ca2+ with BAPTA, suppressed PGF2 alpha-induced phospholipase D (PLD) activation. Neither protein kinase C (PKC) inhibitors nor PKC down-regulation with phorbol 12-myristate 13-acetate affected PGF2 alpha-induced [3H]PEt formation. In permeabilized cells, guanosine 5'-[gamma-thio]triphosphate enhanced PGF2 alpha 's potency in [3H]PEt formation in the presence of Ca2+. The pretreatment of intact cells with pertussis toxin failed to inhibit PGF2 alpha-induced [3H]PEt formation. PGF2 alpha caused a biphasic production of [3H]1,2-diacylglycerol ([3H]1,2-DAG) in [3H]glycerol-labelled cells. The initial transient phase was decreased by U73122, whereas the late sustained phase was decreased by ethanol and the phosphatidic acid phosphohydrolase inhibitor, propranolol. From these results, it was suggested that PGF2 alpha-induced PLD activation was mediated by the dual control of the [Ca2+]i increase due to PI-PLC activation and activation of pertussis-toxin-insensitive G-protein, but not mediated by PKC, and also that PLD activation was involved in the late sustained 1,2-DAG generation in MC3T3-E1 cells.
