Pericytes in castration-resistant prostate cancer associated with disease progression and immunotherapy response: insights from single-cell analysis.

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
backgroundThe current immunotherapeutic strategies yield limited therapeutic benefits in patients with castration-resistant prostate cancer (CRPC) due to its immunologically "cold" tumor milieu. Pericytes play a pivotal role in facilitating metastatic dissemination and modulating immune response in malignancies. Our investigation is designed to decipher the biological effects of pericytes on CRPC and their interactions with the tumor microenvironment.
methodsWe leveraged single-cell transcriptomics and immunofluorescence staining to ascertain the presence and spatial distribution of pericytes in prostate cancer (PCa). Subsequently, we thoroughly delineated the phenotypic and functional characteristics of the CRPC-pericytes subpopulation. The clinical and prognostic significance of CRPC-pericytes was assessed by employing several bulk RNA-seq and microarray datasets. Additionally, we examined the association between the abundance of CRPC-pericytes and immunological features in the PCa microenvironment. Furthermore, the RM-1 subcutaneous tumor model was leveraged to assess the synergistic efficacy of platelet-derived growth factor (PDGF) signaling inhibition in conjunction with immunotherapeutic interventions.
resultsWe discerned pericytes according to their marker genes and observed the α-SMA-positive pericytes encircling the vasculature in PCa and adjacent normal tissues. In the CRPC-pericytes subpopulation, a pronounced upregulation of PDGF signaling and angiogenesis was observed, whereas antitumor immunity-related pathways were suppressed. In addition, CRPC-pericytes displayed notably enhanced interactions with endothelial cells, fibroblasts, and myeloid cells, compared to PCa-pericytes. Patients with elevated prevalence of CRPC-pericytes exhibited notably reduced recurrence-free survival and unresponsiveness to immunotherapeutic interventions. Moreover, CRPC-pericytes were positively associated with immunosuppressive properties of the TME. Notably, combinatorial application of PDGFR inhibitor and anti-PD-1 therapy elicited substantial synergistic antitumor effects in murine PCa models.
conclusionOur investigation uncovers a CRPC-pericytes subpopulation implicated in cancer progression and immunosuppression, suggesting that therapies targeting the phenotypic transition of pericytes could act synergistically with immunotherapeutic regimens to improve survival rates in CRPC.
