Reduced expression of SETD2 and SNX9 proteins in chemically induced mammary tumorigenesis in Wistar rats: a prognostic histological and proteomic study.
Article in Protoplasma, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Breast cancer is a major global health concern, appealing for precise prognostic approaches. Thus, the need is to have studies focusing on the identification and recognition of preliminary events leading to the disease. The present study reports the tracing of precancerous progression and serum proteomic analysis in a breast cancer model developed as a result of 7,12-dimethylbenz[a]anthracene (DMBA) administration. Mammary gland histological changes of prime importance were examined by histopathology, and immunohistochemical analysis with Ki-67 was performed to monitor enhanced cell proliferation, right from the onset of hyperplasia till neoplasia. Serum proteomics (one-dimensional (1D) and two-dimensional (2D) electrophoresis, followed by MALDI-TOF MS characterization) was performed to decipher the differentially expressed serum proteins in animals undergoing tumorigenesis vis-à-vis controls. The significance of our study lies in reporting the significantly reduced expression of two proteins: histone-lysine N-methyltransferase (SETD2) and sorting nexin-9 (SNX9) at very early stage (13 weeks) of tumorigenesis, while the full-fledged tumors developed after 6 months. The reduced expression of SETD2 and SNX9 was validated by western blotting and relative expression analysis using quantitative real-time PCR. These proteins may hence prove as potentially useful tools in search for prognostic markers for the early detection of mammary cancer.
