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

High grade serous ovarian cancer (HGSOC) is the most lethal of all gynecologic malignancies in which the majority of patients eventually develop chemoresistant recurrent disease. Ubiquitin C-terminal hydrolase L1 (UCHL1) is a deubiquitinating enzyme canonically known for its involvement in neurodegeneration, but recently has been shown to play a key role in tumorigenesis. Furthermore, UCHL1 has garnered attention across a multitude of cancer subtypes as it has the ability to be targeted through small molecule inhibition. Therefore, the goal of this present study was to elucidate mechanistic consequences of small molecule UCHL1 inhibition in HGSOC. Comparative label-free proteomic analysis of HGSOC cell line, OVCAR8 revealed prominent changes in cell metabolism proteins upon treatment with UCHL1 small molecule inhibitor, LDN-57444. Further validation via Western blot analysis revealed that changes in cell metabolism proteins differed in matched chemosensitive versus chemoresistant HGSOC cells. Finally, cell viability analysis demonstrated that a combinatorial carboplatin and LDN-57444 blockade produced a promotion or conversely, inhibition of cell death, in chemoresistant, and chemosensitve HGSOC cells, respectively. This phenomenon was further corroborated by respective differences in activation levels of common tumor cell growth pathways STAT3, MAPK/ERK, and AKT in chemoresistant versus chemosensitive HGSOC cells. Overall, this investigation established that pharmacologic targeting of UCHL1 produces differential effects according to HGSOC chemosensitivity status.
