The response of metastatic disease to standard treatment is heterogeneous. As for now, there is no curative treatment option available for metastatic PCa, and the clinical tests capable of predicting metastatic dissemination and metastatic response to the therapies are lacking. Our recent study identified aldehyde dehydrogenases ALDH1A1 and ALDH1A3 as critical regulators of PCa metastases. Still, the exact mechanisms mediating the role of these proteins in PCa metastatic dissemination remain not fully understood, and plasma‑based biomarkers of these metastatic mechanisms are not available.  \nMethods Genetic silencing, gene overexpression, or treatment with different concentrations ofthe retinoic acid (RA) isomers, which are the products of ALDH catalytic activity, were used to modulate the interplay between retinoic acid receptors (RARs) and androgen receptor (AR) . RNA sequencing (RNAseq), reporter gene assays, and chromatin immu‑ noprecipitation (ChIP) analysis were employed to validate the role of RARs and AR in the regulation of the transform‑ ing growth factor‑beta 1 (TGFB1) expression. Gene expression levels of ALDH1A1, ALDH1A3, and the matrix metal‑ loproteinase 11 (MMP11) and their correlation with pathological parameters and clinical outcomes were analysed by mining several publicly available patient datasets as well as our multi‑center transcriptomic dataset from patients with high‑risk and locally advanced PCa. The level of MMP11 protein was analysed by enzyme‑linked immunosorbent assay (ELISA) in independent cohorts of plasma samples from patients with primary or metastatic PCa and healthy donors, while plasma proteome profiles were obtained for selected subsets of PCa patients.  \n*Correspondence: Anna Dubrovska[a.dubrovska@hzdr.de](a.dubrovska@hzdr.de)  \nFull list of author information is available at the end of the article  \n© The Author(s) 2025.
