1 · What the graph read from it

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.

2 · The registry

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

During tumorigenesis, cancer cells generate complex, unresolved interactions with the surrounding oxystressed cellular milieu called tumor microenvironment (TM) that favors spread of cancer to other body parts. This dissemination of cancer cells from the primary tumor site is the main clinical challenge in cancer treatment. In addition, the significance of enhanced oxidative stress in TM during cancer progression still remains elusive. Thus, the present study was performed to investigate the molecular and cytoskeletal alterations in breast cancer cells associated with oxystressed TM that potentiates metastasis. Our results showed that depending on the extent of oxidative stress in TM, cancer cells exhibited enhanced migration and survival with reduction of chemosensitivity. Corresponding ultrastructural analysis showed radical cytoskeletal modifications that reorganize cell-cell interactions fostering transition of epithelial cells to mesenchymal morphology (EMT) marking metastasis, which was reversed upon antioxidant treatment. Decreased E-cadherin and increased vimentin, Twist1/2 expression corroborated the initiation of EMT in oxystressed TM-influenced cells. Further evaluation of cellular energetics demonstrated significant metabolic reprogramming with inclination towards glucose or external glutamine from TM as energy source depending on the breast cancer cell type. These observations prove the elemental role of oxystressed TM in cancer progression, initiating EMT and metabolic reprogramming. Further cell-type specific metabolomic analysis would unravel the alternate mechanisms in cancer progression for effective therapeutic intervention. Graphical abstract Schematic representation of the study and proposed mechanism of oxystressed TM influenced cancer progression. Cancer cells exhibit a close association with tumor microenvironment (TM), and oxystressed TM enhances cancer cell migration and survival and reduces chemosensitivity. Oxystressed TM induces dynamic cytomorphological variations, alterations in expression patterns of adhesion markers, redox homeostasis, and metabolic reprogramming that supports epithelial to mesenchymal transition and cancer progression.
