Differential behaviors of trastuzumab-sensitive and -resistant SKBR3 cells treated with menadione reveal the involvement of Notch1/Akt/FOXO1 signaling elements.

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
Given that HER2 serves as a putative target for therapy in HER2-positive breast cancer, intrinsic and/or acquired resistance to trastuzumab (T) has been proposed to be the major obstacle in treatments. In addition, chemoresistance is commonly attributed to increased antioxidant capacity. In that regard, we evaluated the effect of menadione (M) alone and/or its combination with trastuzumab on proliferation, intracellular GSH and ROS contents as well as HER2 and Notch1 signaling pathways in both trastuzumab-resistant (SKBR3(R)) and -sensitive SKBR3 (SKBR3(S)) cells. In spite of increased level of ROS and reduced level of GSH in M-treated SKBR3(S) cells, M-treated SKBR3(R) cells showed a decreased content of ROS and GSH compared to untreated cells. However, M/T co-treatment of SKBR3 cells indicated no effect on ROS content, while decreased the level of GSH compared to untreated control cells. Based on the extent of apoptosis, colony formation and wound healing assays, M alone, and/or in combination with T had a stronger inhibitory effect on proliferation of SKBR3(R) cells relative to SKBR3(S) cells. These effects might be due to the stronger effects of M and/or M/T on downregulation of p-Akt, Hes1, NICD, and upregulation of FOXO1 among SKBR3(R) cells relative to the sensitive SKBR3 cells. These findings would certainly shed light on some of the signaling factors involved in induction of trastuzumab resistance and would be of value in designing more efficient chemosensitization strategies.
