Expression of a bee venom phospholipase A2 from Apis cerana cerana in the baculovirus-insect cell.

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
Bee venom phospholipase A(2) (BvPLA(2)) is a lipolytic enzyme that catalyzes the hydrolysis of the sn-2 acyl bond of glycerophospholipids to liberate free fatty acids and lysophospholipids. In this work, a new BvPLA(2) (AccPLA(2)) gene from the Chinese honeybee (Apis cerana cerana) venom glands was inserted into bacmid to construct a recombinant transfer vector. Tn-5B-4 (Tn) cells were transfected with the recombinant bacmid DNA for expression. Sodium dodecylsulfate-polyacrylamide gel electrophoresis (SDS-PAGE) analysis revealed a double band with molecular weights of 16 and 18 kDa. Products of hexahistidine AccPLA(2) fusion protein accumulated up to 5.32% of the total cellular proteins. The AccPLA(2) fusion protein was cross reactive with the anti-AmPLA(2) (BvPLA(2) of the European honeybee, Apis mellifera) polyclonal serum. The reaction resulted in a double glycosylation band, which agrees with the band generated by the native AmPLA(2) in Western blot analysis. The PLA(2) activity of the total extracted cellular protein in the hydrolyzing egg yolk is about 3.16 micromol/(min.mg). In summary, the recombinant AccPLA(2) protein, a native BvPLA(2)-like structure with corresponding biological activities, can be glycosylated in Tn cells. These findings provided fundamental knowledge for potential genetic engineering to produce AccPLA(2) in the pharmaceutical industry.
