The dual PI3K/mTOR inhibitor dactolisib elicits anti-tumor activity
Article in Oncotarget, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 23 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
Glioblastomas (GBMs) are among the most malignant of all human tumors and have poor prognosis. The current standard of care (SOC) includes maximal surgical tumor resection followed by adjuvant temozolomide (TMZ) and concomitant radiotherapy (RT). However, even with this treatment, the 5-year survival rate is less than 10%, and thus, follow-up treatment is required to improve efficacy. In GBMs as well as many other solid cancers, PI3K/mTOR signaling is overactivated. Therefore, multiple tumor-based PI3K inhibitors have been studied in various cancers. In the current study, we investigated the effect of the dual PI3K/mTOR inhibitor dactolisib on TMZ+RT treatment in three human GBM cell lines and a orthotopic xenograft model. Dactolisib alone induced cytotoxicity and pro-apoptotic effects, which act as antitumor factors. Combined with SOC treatment, dactolisib inhibited cell viability, induced enhanced pro-apoptotic effect, and attenuated migration/invasion in all three cell lines, thereby enhancing the SOC therapeutic effect. Protein microarray analysis showed that A172 cells treated with TMZ+RT+dactolisib had higher p27 and lower Bcl-2 expression than other groups. Moreover, in the xenograft model, oral dactolisib combined with TMZ+RT inhibited tumor growth and prolonged survival. Thus, SOC combined with dactolisib shows potent anti-tumor activity and has promising potential for solid tumor treatment.
