Thrombospondin-1 induces CD8
Article in Journal of ovarian research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
backgroundOvarian cancer (OC) progression is heavily influenced by the tumor microenvironment (TME), where immune suppression plays a critical role. This study explores the role of thrombospondin-1 (THBS1) in regulating tumor-associated macrophages (TAMs), T cell exhaustion, and immune checkpoint expression, as well as its transcriptional regulation by SNF2H.
methodsWe analyzed THBS1 expression and its clinical significance using publicly available datasets (TCGA-OV, GSE14407) and tissue microarrays containing OC and adjacent normal tissues. In vitro functional studies were conducted using OC cell lines (SKOV3, A2780) and co-cultures with macrophages. Chromatin immunoprecipitation (ChIP) assays and RNA interference were employed to investigate SNF2H-mediated transcriptional regulation of THBS1. In vivo, the role of THBS1 in immune suppression was validated using mouse tumor models.
resultsTHBS1 was significantly overexpressed in OC tissues and associated with poor prognosis. High levels of THBS1 correlated with increased TAM infiltration, M2 macrophage polarization, and upregulation of immune checkpoints PD-L1 and GAL-3, which contribute to T cell exhaustion. Functional assays demonstrated that THBS1 promotes macrophage recruitment and induces M2 polarization through TGF-β1 and IL-4 signaling. Additionally, ChIP assays identified SNF2H as a transcriptional regulator of THBS1, contributing to its overexpression. In vitro targeting of THBS1 reduced TAM-mediated immune suppression and restored T cell cytotoxicity.
conclusionThis study positions THBS1 as a key regulator of the OC TME, linking TAM recruitment and polarization to CD8
