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

Oxaliplatin resistance is one of the main causes of failed colorectal cancer treatment, followed by recurrence and metastasis. In this study, we found that colorectal cancer cells secrete a high level of hyaluronic acid (HA), which interacts with its receptor CD44v6 to mediate colorectal cancer resistance to chemotherapy. HA oligosaccharide (oHA) is a degradation product of HA. We found that it competitively binds to CD44v6, reversing the HA-CD44v6-mediated effect of HA on oxaliplatin resistance. In addition, oHA showed no toxicity or immunogenicity but exhibited good biocompatibility and tumor-targeting capability. Therefore, we synthesized oHA-loaded oxaliplatin liposome nanoparticles (oHA-Lipid-Oxa) using a thin-film hydration method. The cytotoxicity of oHA-Lipid-Oxa was assessed in vitro using flow cytometry, which revealed greater lethality than oxaliplatin alone. Finally, we established a tumor-bearing nude mouse model and separately injected oHA-Lipid-Oxa, Lipid-Oxa, Oxa, oHA, and phosphate-buffered saline (PBS) into the tail vein to observe the antitumor effects of nanoparticles in vivo. The oHA-Lipid-Oxa group exhibited the highest tumor suppression rate, but the weight loss was not obvious. Hematoxylin and eosin staining showed greatest lymphocyte and macrophage infiltration in the oHA-Lipid-Oxa group. Moreover, oHA-Lipid-Oxa induced tumor cell apoptosis and necrosis most robustly compared with the other groups. We showed that oHA-Lipid-Oxa has excellent histocompatibility and CD44v6-targeting capabilities, thus greatly increasing the sensitivity to oxaliplatin and reducing adverse reactions. Accordingly, oHA-Lipid-Oxa has a broad potential for therapeutic application.
