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

Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer comprised of cells that lack expression of targetable biomarkers. Nucleic acid aptamers are a group of molecular ligands that can specifically bind to their targets with high affinity. The ssDNA aptamer PDGC21-T recognizes poorly differentiated cancer cells and tumor tissues through an unidentified cell surface target(s). Because TNBC tumor cells are poorly differentiated, the aptamer PDGC21-T is a promising therapeutic candidate to target TNBC tumor cells. In vitro study revealed that synthetic aptamer probes selectively targeted TNBC cell lines. To assess aptamer immunotherapeutic targeting capability, we generated aptamer-engineered NK cells (ApEn-NK) using aptamer probes as a targeting ligand and NK cells as a therapeutic agent. Cell clustering formation assays revealed that ApEn-NK bound both suspended and adherent TNBC cells with high affinity. In a functional study, ApEn-NK treatment triggered apoptosis and death of cultured TNBC cells. Finally, systemic administration of ApEn-NK in mice harboring TNBC xenografts resulted in significant inhibition of lung metastasis relative to parental NK cell treatments. Unlike chemotherapy, ApEn-NK treatment did not affect body weight in treated mice. We demonstrate a novel approach for targeted TNBC immunotherapy.
