Overexpression of Glyoxalase 2 in Human Breast Cancer Cells: Implications for Cell Proliferation and Doxorubicin Resistance.
Article in International journal of molecular sciences, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Glyoxalase 2 (Glo2) is an enzyme of the glyoxalase system whose pathway parallels glycolysis and which aims to remove methylglyoxal (MGO). This study analyzed the possible additional roles of the Glo2 enzyme in breast cancer (MCF7) and non-cancer (HDF) cell lines, investigating its presence at the nuclear level and its potential involvement in cell proliferation and chemotherapy resistance. The results revealed that Glo2 is overexpressed in cancer cells, and its expression is higher during the proliferative (S and G2/M) phases of the cell cycle. The study also examined a post-translational modification (PTM) in which Glo2 could be involved, with S-glutathionylation revealing that Glo2 enhances this PTM in cancer cells both in the cytoplasm and nucleus. Inhibition of Glo2 by p-NCBG resulted in increased sensitivity to doxorubicin, a common chemotherapeutic agent. This suggests that Glo2 increases cancer cell resistance to chemotherapy, potentially through its role in regulating oxidative stress. These results highlight Glo2 as a potential therapeutic target to improve the efficacy of existing treatments.
