Characterization of Immunogenic Cell Death Related Molecular Subtypes and Its Therapeutic Implications for Prostate Adenocarcinoma
This study investigates immunogenic cell death (ICD)-related gene expression patterns in prostate adenocarcinoma (PRAD), explores the potential for ICD activation to induce anticancer effects, and identifies molecular subtypes in PRAD. Datasets from TCGA and GEO were analyzed using
R software to assess ICD-related gene expression changes. Up-regulated genes included EIF2AK3, FOXP3, BAX, PDIA3, CALR, and CASP8, while down-regulated genes included IL1R, PIK3CA, IL17A, and others. Western blot confirmation supported the up-regulation of EIF2AK3, FOXP3, BAX, PDIA3, CALR,
and CASP8. Clustering 497 samples based on 33 ICD-related genes revealed three molecular subtypes, with distinct gene functions and varying PD-L1 expression levels. The PRAD tumor microenvironment exhibited an abundance of resting dendritic cells and rare activated dendritic cells. This study
suggests that diverse ICD-related genes are expressed in PRAD, leading to the classification of three molecular subtypes, which could guide precise molecular-level treatments. Additionally, the presence of resting dendritic cells in the PRAD tumor microenvironment hints at the potential for
ICD-based therapies to activate these cells for anti-tumor effects.
期刊介绍:
ACS Applied Bio Materials is an interdisciplinary journal publishing original research covering all aspects of biomaterials and biointerfaces including and beyond the traditional biosensing, biomedical and therapeutic applications.
The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrates knowledge in the areas of materials, engineering, physics, bioscience, and chemistry into important bio applications. The journal is specifically interested in work that addresses the relationship between structure and function and assesses the stability and degradation of materials under relevant environmental and biological conditions.
