Approach for chemosensitization of cisplatin-resistant ovarian cancer by cucurbitacin B.
Article in Tumour biology : the journal of the International Society for Oncodevelopmental Biology and Medicine, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 25 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
Ovarian cancer is the most deadly gynecological cancer. The first line in treatment is platinum-based drugs. However, most patients suffer from tumor recurrence, characterized by resistance to cisplatin. A plausible approach to address the tumor resistance is to co-administer the chemotherapeutic agents along with natural products to offer a synergistic effect and optimize the dosage regimen. Cucurbitacin B is a natural product and displays antitumor activity against a wide array of cancer cell lines. The aim of this work is to determine the antitumor activity against ovarian cancer cell line (A2780) and possible sensitization activity on cisplatin-resistant cell line (A2780CP) in 2D and 3D culture model. 3D spheroids were generated from A2780CP cell line. A2780, A2780CP, and the spheroids were treated with cucurbitacin B, cisplatin alone, or pretreated with cucurbitacin B followed by cisplatin. The viability, cell cycle, and apoptosis were analyzed. Level of ROS and total glutathione was measured. In this study, cucurbitacin B showed cytotoxicity against the ovarian cancer cell lines, and pretreatment of A2780CP cells leads to a significant increase in the cytotoxicity of cisplatin. The mechanism behind the sensitization effect was dependent in part on the depletion of the total glutathione, an increase in ROS through a decrease in the level of dual-specificity tyrosine-regulated kinase (Dyrk1B), decrease in pERK1/2 and pSTAT3 level. The viability of spheroids treated with a combination of cisplatin and cucurbitacin B were significantly decreased. The resulting data shows that cucurbitacin B is a promising chemosensitizer for the cisplatin-resistant ovarian cancer.
