Chemoprevention of pancreatic cancer by inhibition of glutathione-S transferase P1.
Article in Investigational new drugs, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Pancreatic cancer is among the most refractory malignancies with poor prognosis. Thus, preventive approaches, in addition to the development of novel therapeutic strategies are essential for this type of cancer. KRAS mutations occur very early in the development of pancreatic cancers and could be targeted for its prevention, yet specific inhibitors for mutated KRAS are lacking. Accordingly, Glutathione-S Transferase p1 (GSTP1), which we recently found to be an autocrine stimulator of mutated KRAS signaling, is predicted to be an alternative target for chemoprevention of pancreatic cancer. In this study, chemopreventive effects of O-Hexadecyl-γ-glutamyl-S-benzyl-cysteinyl-D-phenyl glycine-Ethylester (HGBPE), which we previously synthesized to inhibit GSTP1 activity, was analyzed for its effect on the prevention of a rat pancreatic carcinogenesis model induced by 7,12-dimethyl-benzanthracene (DMBA). Rats administered with DMBA were grouped into five cohorts. In the treated group I, which was treated neither with HGBPE nor vehicle, sequential appearance of precancerous lesions, ductal complexes, and adenocarcinoma was confirmed as previously reported. We also confirmed in this group that mutations of KRAS and expression of GSTP1 simultaneously occurred in the ductal complex. To rats of groups II and IV, HGBPE was administered, and vehicle to those of group III and V. In groups of II and IV, the incidence of both ductal complex and adenocarcinoma were significantly lower than those in groups III and V. These data clearly suggest the efficacy of HGBP as a potential chemopreventive agent for pancreatic cancer.
