An intracellular antibody can suppress tumorigenicity in hepatitis B virus X-expressing cells.

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
Although the hepatitis B virus X protein (HBx) is thought to play a causative role in the development of hepatocellular carcinoma, it is not yet known whether interfering with HBx function may affect the cellular transformation of HBx-expressing tumor cells. To address this question, we adopted an intracellular antibody fragment expression approach to block the function of HBx. Expression of a single-chain variable fragment (scFv) specific to HBx (designated as H7scFv) inhibited HBx-dependent cellular transactivation. Furthermore, H7scFv suppressed the growth of HBx-expressing tumor cells in both soft agar and nude mice. The suppressive effect of H7scFv on tumorigenicity appeared not to be mediated by inhibition of HBx-induced growth stimulation since the growth rate of these cells was not affected significantly by H7scFv expression. In conclusion, these data suggest that the HBx-dependent transformed phenotype is reversible and that HBx may be a good molecular target for the treatment of HBV-related tumors.
