A new nodavirus-negative Trichoplusia ni cell line for baculovirus-mediated protein production.
Article in Biotechnology and bioengineering, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Cell lines derived from Trichoplusia ni (Tn) are widely used as hosts in the baculovirus-insect cell system (BICS). One advantage of Tn cell lines is they can produce recombinant proteins at higher levels than cell lines derived from other insects. However, Tn cell lines are persistently infected with an alphanodavirus, Tn5 cell-line virus (TnCLV), which reduces their utility as a host for the BICS. Several groups have isolated TnCLV-negative Tn cell lines, but none were thoroughly characterized and shown to be free of other adventitious viruses. Thus, we isolated and extensively characterized a new TnCLV-negative line, Tn-nodavirus-negative (Tn-NVN). Tn-NVN cells have no detectable TnCLV, no other previously identified viral contaminants of lepidopteran insect cell lines, and no sequences associated with any replicating virus or other viral adventitious agents. Tn-NVN cells tested negative for >60 species of Mycoplasma, Acholeplasma, Spiroplasma, and Ureaplasma. Finally, Tn-NVN cells grow well as a single-cell suspension culture in serum-free medium, produce recombinant proteins at levels similar to High Five™ cells, and do not produce recombinant glycoproteins with immunogenic core α1,3-fucosylation. Thus, Tn-NVN is a new, well-characterized TnCLV-negative cell line with several other features enhancing its utility as a host for the BICS.
