Our scRNA-seq analyses revealed significant alterations in the tumor microenvironment following GCP therapy: tumor-infiltrating macrophages underwent a distinct antitumor phenotypic shift, transitioning from M2 toward M1 polarization; concurrently, CD8+ T cells exhibited enhanced costimulatory signaling characterized by CD81 upregulation and malignant cells demonstrated diminished immune escape characteristics alongside heightened activity in immune response-related pathways. Our preliminary findings reveal a generally reactivated antitumor immune response in ICC following GCP therapy, which could partly illuminate the enigmatic black box of intra-tumoral cellular states associated with treatment response.
Our findings reveal a novel mechanism whereby CUL2 promotes PC progression and ferroptosis resistance through regulation of the KEAP1-NRF2 axis. CUL2 overexpression enhances cellular antioxidant capacity and maintains mitochondrial integrity, thereby conferring broad resistance to ferroptosis-inducing conditions. This study suggests that targeting the CUL2-NRF2 axis to enhance ferroptosis sensitivity might represent a promising therapeutic strategy for PC treatment.

GEM-loaded CaP NPs showed high cytotoxicity in FRα-overexpressing cancer cell lines (MCF-7, MDA-MB-231, HeLa), while FA conjugation significantly reduced toxicity in hMSCs without compromising anticancer activity. These findings demonstrate the potential of FA-conjugated and GEM-loaded CaP NPs as a nanoplatform for targeted cancer therapy with reduced toxicity in healthy cells.
