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

Ferroptosis is an iron-dependent regulated cell death characterized by lipid peroxidation accumulation. Due to the high iron demand of cancer cells, targeting ferroptosis is considered a promising approach for cancer therapy. This study aimed to elucidate the mechanisms underlying the differences in ferroptosis sensitivity in non-small cell lung cancer (NSCLC) cells and identify strategies to overcome ferroptosis resistance. H1299 cells were more sensitive to cysteine deprivation-induced ferroptosis and exhibited higher transferrin receptor (TfR) expression than H460 cells. Transferrin enhanced ferroptosis in cysteine-deprived H1299 cells, while TfR knockdown reduced ferroptosis, suggesting the involvement of TfR/transferrin system in this process. In H460 cells with low TfR expression, transferrin treatment did not induce ferroptosis under cysteine deprivation, indicating that the TfR/transferrin system was not involved. However, treatment with cell-permeable ferric ammonium citrate increased the sensitivity of ferroptosis to cysteine deprivation or RSL3 treatment. In conclusion, iron overload could be a potential strategy to overcome ferroptosis resistance in NSCLC.
