Oncogenic DNA methyltransferase 1 activates the PI3K/AKT/mTOR signalling by blocking the binding of HSPB8 and BAG3 in melanoma.

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
Abnormal DNA methylation has been observed in multiple malignancies, including melanoma. In this study, we initially noticed the overexpression of DNA methyltransferase 1 (DNMT1) in melanoma samples in bioinformatics analysis and, subsequently, validated it in the purchased melanoma cell lines. After treatment with short-hairpin RNAs or Decitabine (a DNA methylation inhibitor), silencing of DNMT1 was demonstrated to suppress cell viability and invasive and migratory potentials as well as to augment apoptosis and autophagy in melanoma cells. To further explore the downstream mechanisms, we revealed that DNMT1 inhibited HSPB8 expression through augmenting HSPB8 methylation, thereby suppressing the binding between HSPB8 and BAG3. Then, we elucidated through a series of gain- and loss- of function assays that the interplay of HSPB8 and BAG3 blocked the PI3K/AKT/mTOR pathway, thereby repressing the malignant phenotypes of melanoma cells and contributing to melanoma cell apoptosis and autophagy. We further established a mouse model of melanoma and substantiated that DNMT1 enhanced the
