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

Osteosarcoma malignancy exhibits significant heterogeneity, comprising both osteosarcoma stem cells (OSCs) and non‑OSCs. OSCs demonstrate increased resistance to chemotherapy due to their distinctive cellular and molecular characteristics. Alterations in mitochondrial morphology and homeostasis may enhance chemoresistance by modulating metabolic and regulatory processes. However, the relationship between mitochondrial homeostasis and chemoresistance in OSCs remains to be elucidated. The present study employed high‑resolution microscopy to perform multi‑layered image reconstructions for a quantitative analysis of mitochondrial morphology. The results indicated that OSCs exhibited larger mitochondria in comparison with non‑OSCs. Furthermore, treatment of OSCs with cisplatin (CIS) or doxorubicin (DOX) resulted in preserved mitochondrial morphological stability, which was not observed in non‑OSCs. This finding suggested a potential association between mitochondrial homeostasis and chemoresistance. Further analysis indicated that dynamin‑related protein 1 (DRP1) might play a pivotal role in maintaining the stability of mitochondrial homeostasis in OSCs. Depletion of DRP1 resulted in the disruption of mitochondrial stability when OSCs were treated with CIS or DOX. Additionally, knocking out DRP1 in OSCs led to a reduction in chemoresistance. These findings unveil a novel mechanism underlying chemoresistance in osteosarcoma and suggest that targeting DRP1 could be a promising therapeutic strategy to overcome chemoresistance in OSCs. This provided valuable insights for enhancing treatment outcomes among patients with osteosarcoma.
