Potential Otubain1 Inhibitor, an Approach for a Treatment against Breast Cancer.

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
The develop of new anticancer drug continues worldwide and one of the new therapeutic targets to reach it is Otubain 1 (OTUB1), since OTUB1 has functions related to prognosis in a variety of tumors and is strongly related to tumor proliferation, migration, and apoptosis by their functions on deubiquitinating. This study uses OTUB1´s active site to develop a specific pharmacological treatment to regulate the OTUB1 functions. The aim of this research was to evaluate the effects of ten compounds (OT1 - OT10), that previously were selected by molecular docking to develop a new anticancer drug to decrease the OTUB1 functions in the cancer processes. We evaluated the cytotoxic effect of OT1 - OT10 compounds on MCF-7, BT474 and MDA-MB 231 cells by MTT assay, and we determined characteristics of apoptosis by western blot analysis. Then, the best compound (OT5) was analyzed by molecular docking, molecular dynamics and theoretical toxicity for describing the interactions of OT5 compound with the OTUB1´s active site. We proposed that the OT5 compound has a high probability to be selective against OTUB1, with an apoptosis (regulating caspase-8) and cytotoxic effect on some cancer lines; IC50 for MCF-7: 97 µM and MDA-MB 231:147 µM, as well as we described that this compound could have specific interactions in the catalytic domain of OTUB1, modifying this protein's activity, decreasing the OTUB1 functions, and probably safe for humans. These results show the high potential of this compound for promoting the development of this compound as a new drug against cancer.
