Estrogen exposure causes the progressive growth of SK-Hep1-derived tumor in ovariectomized mice.

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
Liver cancer, one of the leading death causes, has different incidence and mortality rates in men and women. The influencing factor is considered to estrogen. However, the role of estrogen in liver cancer remains controversial. In this study, we investigated the effects of estrogen on tumor progression. Total RNA sequencing was analyzed in SK-Hep1-derived tumor tissues, and 15 genes were expressed only in female mice. Among the differentially expressed genes, matrix metalloprotease 7 (MMP7), germ cell associated 1 (GSG1), and chromosome 6 open reading frame 15 (C6orf15) were associated with significantly different overall survival rates based on their expression level in liver cancer patients. Interestingly, exogenous estrogen aggravated SK-Hep1-derived tumor growth in ovariectomized (OVX) mice. When OVX mice were treated with exogenous estrogen, SK-Hep1-derived tumor tissues exhibited high MMP7 expression levels and low GSG1 and C6orf15 expression levels. These expression patterns were consistent with those of liver cancer patients with low overall survival rates. These results suggest that these genes are expected to be prognostic biomarkers of liver cancer. In conclusion, our results suggest that continuous estrogen exposure may promote tumor growth in OVX mice.
