Cell-cycle-dependent gene expression studied by two-colour fluorescent detection of a mRNA and histone mRNA.

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
We investigated whether a probe specific for histone H3 mRNA could be used as a marker to study cell-cycle dependency of gene expression by double-fluorescent RNA in situ hybridization (FISH). First, we showed that all S-phase cells in cell cultures having incorporated BrdU revealed histone H3 mRNA expression by RNA FISH, indicating that histone H3 expression is a reliable marker for S-phase cells. Second, we analysed whether the expression of human cytomegalovirus immediate early genes in rat 9G cells, which are known to be induced in an S-phase dependent way by cycloheximide, correlated with the expression of histone H3 mRNA. Double-hybridization experiments with a digoxigenin-labelled probe for IE mRNA and a fluoresceinated probe for histone H3 mRNA revealed that cells expressing IE mRNA also expressed histone H3 mRNA. Third, we examined the cell-cycle dependency of luciferase gene expression in X1 cells. Luciferase mRNA is heterogeneously expressed in X1 cell cultures, but cells expressing luciferase did not necessarily express histone H3 mRNA. This indicates that luciferase gene expression in X1 cells is not induced during S-phase. The results of our study show that histone H3 mRNA expression can be successfully used as a marker to establish cell-cycle dependency of gene expression by double-RNA FISH.
