1 · What the graph read from it

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.

2 · The registry

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

Although persistent infections with high‑risk human papilloma virus (HPV) constitute the most significant cofactor for the development of cervical cancer, they are insufficient on their own. Mutations or epigenetic inactivation of the tumor suppressor adenomatous polyposis coli (APC), the two acting as prominent oncogenic mechanisms in a number of types of cancer, are frequently associated with aberrant activation of the Wnt/β‑catenin pathway. According to these observations, it was hypothesized that APC alteration may lead to β‑catenin deregulation and the abnormal expression of direct targets of the Wnt pathway in HPV‑infected cervical cancer cells. The present study confirmed that the stabilization of β‑catenin correlates with enhanced transcriptional activity of the β‑catenin/T‑cell factor complex in cervical cancer cell lines. Sequence analysis of the 'hot‑spot' in the mutation cluster region did not exhibit genetic alterations that may be associated with APC gene inactivation. In addition, it was identified that there was a good correlation with the hypermethylation status of the APC promoter 1A and the abnormal accumulation of endogenous β‑catenin in cell lines and biopsies infected with HPV16, although not HPV18. Removal of the epigenetic markers led to an increase in APC levels and a reduction of β‑catenin expression in two transcriptional targets of the Wnt pathway: Matrix metalloproteinase‑7 and vascular endothelial growth factor. The present study suggested that the increase in Wnt activity in certain cervical cancer‑derived cells may be associated with an alteration in the methylation status of the APC gene promoter 1A.
