Transplantation of gastric epithelial mitochondria into human gastric cancer cells inhibits tumor growth and enhances chemosensitivity by reducing cancer stemness and modulating gastric cancer metabolism.

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
backgroundGastric cancer is the malignant disease. The problems associated with cancer stemness and chemotherapy resistance in gastric cancer therapy remain unresolved. Glucose-regulated protein 78 (GRP78) is a biomarker of gastric cancer and modulates cancer stemness and chemoresistance. Previous studies have shown that mitochondrial transplantation from healthy cells is a promising method for treating various diseases and that the regulation of mitochondrial metabolism is crucial for modulating the stemness and chemoresistance of cancer cells. The aim of this study was to investigate the therapeutic effect of mitochondrial transplantation from normal gastric epithelial cells into gastric cancer and the associated mechanisms.
methodsThe expression of cancer stemness markers, intracellular oxidative stress, or apoptotic-related proteins were evaluated via flow cytometry. Western blotting was used to investigate the molecular mechanism involved in MKN45 or AGS human gastric cancer cells after transplantation with human gastric epithelial mitochondria. The mitochondrial metabolic function of gastric cancer cells was determined via a Seahorse bioanalyzer, and extracellular lactate was evaluated via bioluminescent assay. The viability of 5-fluorouracil (5-FU)-treated gastric cancer cells was detected via a CCK-8 assay. Furthermore, a xenograft tumor animal study was performed to validate the therapeutic effects of human gastric epithelial mitochondrial transplantation in gastric cancer. Immunohistochemistry and Western blotting were then used to assess the expressions related to cancer stemness and mitochondrial metabolism-related proteins in tumor tissues.
resultsTransplanting human gastric epithelial mitochondria downregulates gastric cancer mitochondrial biogenesis, glycolysis, GRP78-mediated cancer stemness, and increases oxidative stress, cell apoptosis under hypoxic conditions and chemosensitivity in response to 5-FU treatment. Moreover, the transplantation of epithelial mitochondria into gastric tumors inhibited the tumor growth in vivo tumor graft animal models. Therefore, mitochondrial transplantation can be considered for the treatment of gastric cancer.
