Exploring the oncogenic role of RGS19 in bladder cancer progression and prognosis
This study investigates the role of autophagy-related genes (ARGs) in bladder cancer (BLCA), focusing on the regulator of G protein signaling 19 (RGS19). Using data from The Cancer Genome Atlas (TCGA) and the Human Autophagy Database (HADb), we identified RGS19 as significantly upregulated and linked to poor prognosis in BLCA. Kaplan-Meier survival analysis confirmed its association with increased mortality and. In vitro, RGS19 knockdown in BLCA cell lines inhibited proliferation, migration, and invasion, while inducing apoptosis and autophagy. Transmission electron microscopy showed autophagic structures in RGS19-silenced cells. In vivo, a xenograft mouse model demonstrated reduced tumor growth with RGS19 knockdown. Immunohistochemical (IHC) analysis revealed decreased Ki67 and increased autophagy markers in tumors with reduced RGS19. Pathway analysis suggested RGS19 acts through the cGMP-PKG signaling pathway, validated by altered expression of soluble guanylate cyclase (sGC), protein kinase G (PKG1), phosphodiesterase 5 A (PDE5A), vasodilator-stimulated phosphoprotein (VASP), and phosphorylated VASP (p-VASP) upon RGS19 knockdown. These results highlight RGS19 as a potential biomarker and therapeutic target in BLCA.
期刊介绍：
Acta histochemica, a journal of structural biochemistry of cells and tissues, publishes original research articles, short communications, reviews, letters to the editor, meeting reports and abstracts of meetings. The aim of the journal is to provide a forum for the cytochemical and histochemical research community in the life sciences, including cell biology, biotechnology, neurobiology, immunobiology, pathology, pharmacology, botany, zoology and environmental and toxicological research. The journal focuses on new developments in cytochemistry and histochemistry and their applications. Manuscripts reporting on studies of living cells and tissues are particularly welcome. Understanding the complexity of cells and tissues, i.e. their biocomplexity and biodiversity, is a major goal of the journal and reports on this topic are especially encouraged. Original research articles, short communications and reviews that report on new developments in cytochemistry and histochemistry are welcomed, especially when molecular biology is combined with the use of advanced microscopical techniques including image analysis and cytometry. Letters to the editor should comment or interpret previously published articles in the journal to trigger scientific discussions. Meeting reports are considered to be very important publications in the journal because they are excellent opportunities to present state-of-the-art overviews of fields in research where the developments are fast and hard to follow. Authors of meeting reports should consult the editors before writing a report. The editorial policy of the editors and the editorial board is rapid publication. Once a manuscript is received by one of the editors, an editorial decision about acceptance, revision or rejection will be taken within a month. It is the aim of the publishers to have a manuscript published within three months after the manuscript has been accepted
