Dihydrotestosterone Enhances MICA-Mediated Immune Responses to Epstein-Barr Virus-Associated Gastric Carcinoma.
Article in Cancers, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundEpstein-Barr virus-associated gastric carcinoma (EBVaGC) is a subset of gastric cancers linked to EBV infection. While the role of male hormones in cancers such as prostate, breast, and ovarian cancers is well-studied, their impact on EBVaGC remains less understood. This study aims to examine the effect of dihydrotestosterone (DHT) on EBVaGC, particularly focusing on its influence on the immune response.
methodsThe study utilized the SNU719 EBVaGC cell line. Cells were treated with DHT to assess androgen receptor (AR) expression and the activation of signaling pathways, including NF-κB. The expression of MHC class I polypeptide-related sequence A (MICA) and its interaction with the NKG2D receptor on NK and T cells was evaluated. Cytotoxicity assays were conducted to determine DHT's effect on NK and T cell-mediated cytotoxicity, and proinflammatory cytokine gene expression was analyzed.
resultsDHT significantly increased AR expression in EBVaGC cells and activated the NF-κB pathway, which led to increased transcription of target genes such as MICA and EBNA1. These changes enhanced the interaction with receptors on NK and T cells, thereby boosting their cytotoxicity against EBVaGC cells. Importantly, DHT did not upregulate proinflammatory cytokine genes.
conclusionDHT enhances the immune response against EBVaGC by upregulating MICA and activating NK and T cells. These findings suggest potential therapeutic strategies targeting androgen signaling to improve anti-tumor immunity in EBVaGC.
