Glutamine stabilizes myc via alpha-ketoglutarate and regulates paclitaxel sensitivity.
Article in Medical oncology (Northwood, London, England), 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Metabolic reprogramming wherein the cancer cells exhibit altered energetics is a hallmark of cancer. Although recent discoveries have enhanced our understanding of tumor metabolism, the therapeutic utility of targeting tumor metabolism is not yet realized. Glutamine, a non-essential amino acid, plays a critical role in regulating tumor metabolism and provides an alternative tumor energy source. In this study, we investigate the molecular mechanism regulated by glutamine and elucidate if targeting glutamine metabolism would enhance the efficacy of cancer chemotherapy. Using clonogenic and cell cycle analysis, we found that deprivation of glutamine suppress the growth of cancer cells. Mechanistically we demonstrate that glutamine stabilizes myc by preventing its ubiquitination through alpha-ketoglutarate. Inhibition of glutamine metabolism enhanced the sensitivity of tumor cells to chemotherapeutic agent paclitaxel. Our results delineate the mechanism behind glutamine-induced myc stabilization, and they provide a viable strategy to target cancer with a glutamine metabolism inhibitor in the clinic.
