Effect of Ribonuclease A and Deoxyribonuclease I on Immunostaining of Ki-67 in Cultured Melanoma 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
Immunostaining of the cell cycle-associated Ki-67 antigen was studied, using the Ki-67-specific MIB-1 monoclonal antibody on slides prepared by cytocentrifugation of cultured A375 melanoma cells. Immunomorphological analysis of the Ki-67 immunostaining pattern of both nuclear and nucleolar locations was carried out following pre-treatment of the slides including ribonuclease and deoxyribonuclease pre-digestion of the cells. Immunostaining of nucleolar Ki-67 was reduced by ribonuclease pre-digestion, but was not altered by deoxyribonuclease pre-treatment. Ribonuclease did not reduce the staining intensity of Ki-67 in the nuclear matrix, but the intensity decreased after deoxyribonuclease pre-digestion. We suggest that the Ki-67 molecule may play an important role in ensuring contact between nuclear DNA and nucleolar RNA during transcriptional processes in cell proliferation.
