Inhibition of cyclin A gene expression in human B cells by an immunosuppressant mizoribine.
Article in Clinical and experimental immunology, 2000. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Mizoribine has been shown to have beneficial effects in the treatment of rheumatoid arthritis and lupus nephritis, in which abnormal B cell functions are involved. Previous studies demonstrated that mizoribine directly suppresses the function of human B cells. The current study explored in detail the mechanism of the suppression of human B cell responses by mizoribine at the molecular level. Highly purified peripheral blood B cells obtained from normal healthy individuals were stimulated with Staphylococcus aureus Cowan I (SAC) plus IL-2 in the presence or absence of mizoribine or methotrexate for 48 h to 72 h. The expression of cyclin A mRNA was determined by semiquantitative reverse transcriptase-polymerase chain reaction followed by Southern hybridization. Although at pharmacologically attainable concentrations both mizoribine and methotrexate suppressed the production of IgM of SAC-activated B cells, mizoribine, but not methotrexate, decreased the expression of cyclin A protein as well as mRNA in B cells stimulated with SAC + IL-2. Of note, mizoribine facilitated the degradation of cyclin A mRNA in the presence of actinomycin D, indicating that mizoribine shortens the stability of cyclin A mRNA. The results indicate that mizoribine suppresses the expression of cyclin A mRNA in human B cells by down-regulating its stability, and thus down-regulates their responses.
