Downregulation of UPK1A suppresses proliferation and enhances apoptosis of bladder transitional cell carcinoma cells.
Article in Medical oncology (Northwood, London, England), 2015. 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
Uroplakin 1A (UPK1A) is a specific marker of mammalian urothelium and one of major proteins contained in urothelial plaques. Many recent studies reported that UPK1A could be useful marker for diagnosis, detection and prognostic prediction of transitional cell carcinoma. However, relatively little is known about its exact roles in bladder transitional cell carcinoma (BTCC). We tried to explore the roles UPK1A plays in BTCC via the transfection of its antisense nucleotides (AS) into T24 cells to observe their changes of proliferation and apoptosis. After AS was successfully transfected into T24 cells, the percentages of proliferating T24 cells at 24 and 48 h after the treatment were 57.2 ± 6.8 and 44.7 ± 5.2%, significantly lower than that of control group, as shown by MTT (p < 0.05 and 0.01). At 24 h after transfection of AS, the percentage of apoptotic T24 cells was 26.87% measured by flow cytometry, significantly higher than that of control group (p < 0.01). Similarly, Hoechst 33258 staining showed that the percentage of apoptotic nuclei of T24 cells after 24 h treated by AS was 28.9%, significantly higher than that of control (p < 0.05). The most common and typical morphological changes of apoptosis, including shrink, pyknosis and karyorrhexis of T24 cells nuclei and DNA fragmentation were seen from Hoechst 33258 staining and DNA agarose gel electrophoresis. Taken together, inhibition of UPK1A can suppress proliferation and enhance apoptosis of BTCC T24 cells, suggesting it a potential target to treat this disease.
