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

Centrosomal abnormalities have been found in various cancer types. We sought to determine whether centrosomal dysfunctions occur in the atypical ductal hyperplasia (ADH)-carcinoma sequence of breast cancer. As alpha and gamma-tubulins are the structural components of centrosomes, we performed real time quantitative polymerase chain reaction (qPCR), in situ hybridization (ISH) and immunnohistochemistry (IHC) to determine the DNA copy levels, messenger RNA (mRNA) expression, and protein expression of alpha and gamma-tubulins respectively. Gamma-tubulin staining was used for the localization and quantification of centrosomes. We found that alpha-tubulin or gamma-tubulin mRNA was increasingly expressed from normal breast tissue (NBT) to ADH, ductal carcinoma in situ (DCIS), and infiltrative ductal carcinoma (IDC), respectively, with the highest expressions being found in DCIS. The expression profiles of alpha, gamma-tubulin proteins were concordant with that of mRNA, except that the highest expression was found in IDC. Similarly, DNA copies of alpha, gamma-tubulins showed a rising tendency, with the highest level for gamma-tubulin attained in IDC and that for alpha-tubulin was found in DCIS. However, there was no significant difference of alpha, gamma-tubulin DNA copy levels, mRNA expression, and protein expression between DCIS and IDC. Our results demonstrate that centrosomal aberrations may play key roles in the early stage of breast tumorogenesis. The malignant transformation sequence is probably attributable to the amplification of centrosomal DNA leading to mRNA and protein over-expression of these centrosomal proteins. Furthermore, determination of alpha, gamma-tubulins using combined qPCR with ISH may be useful in assisting the diagnosis of premalignant lesions of the breast.
