TIP60 up-regulates ΔNp63α to promote cellular proliferation.

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
An estimated 5.4 million cases of nonmelanoma skin cancer are reported in the United States at an associated cost of $4.8 billion. ΔNp63α, a proto-oncogene in the p53 family of transcription factors, is overexpressed in squamous cell carcinoma (SCC) and associated with poor prognosis and survival. ΔNp63α elicits its tumorigenic effects in part by promoting cellular proliferation and cell survival. Despite its importance in SCC, the upstream regulation of ΔNp63α is poorly understood. In this study, we identify TIP60 as a novel upstream regulator of ΔNp63α. Using a combination of overexpression, silencing, stable expression, and pharmacological approaches in multiple cell lines, we showed that TIP60 up-regulates ΔNp63α expression. Utilizing cycloheximide treatment, we showed that TIP60 catalytic activity is required for stabilization of ΔNp63α protein levels. We further showed that TIP60 coexpression inhibits ΔNp63α ubiquitination and proteasomal degradation. Stabilization of ΔNp63α protein was further associated with TIP60-mediated acetylation. Finally, we demonstrated that TIP60-mediated regulation of ΔNp63α increases cellular proliferation by promoting G
