Cytokines orchestrate these barriers by shaping spatial immune architecture, regulating suppressive myeloid programmes and inducing inhibitory ligands such as PD-L1. In this Review, we synthesize mechanistic and clinical evidence and propose a push–pull framework for cytokine modulation during checkpoint blockade: locally amplifying Th1/CTL-supporting signals (IL-2/IL-12/IL-15 and type I/II interferons) while selectively attenuating dominant suppressive circuits (TGF-β, IL-6/STAT3, IL-8–CXCR1/2, IL-10 and TNF-driven exhaustion). We critically contrast successful and failed cytokine–ICI combinations, highlighting how systemic exposure, network redundancy and counter-regulatory feedback have constrained several engineered agonists and explain why certain blockade strategies can improve efficacy while reducing immune-related toxicity. We discuss next-generation solutions—tumor-activated pro-cytokines, intratumoral gene delivery and immunocytokines—that concentrate activity within resistant niches and widen the therapeutic window. Finally, we outline actionable biomarkers, including transcriptomic signatures, plasma cytokine kinetics, myeloid/neutrophil metrics and spatial TME profiling, to stratify patients and guide dosing, sequencing and adaptive add-on strategies. Rational, biomarker-guided cytokine modulation offers a path to convert immune-excluded tumors into durable ICI responders.</div></div>","PeriodicalId":8782,"journal":{"name":"Biochimica et biophysica acta.

This enables them to reshape the tumor ecosystem into a supportive niche. This review introduces a unified “signal hijacking” framework to decipher this process. First, chemical hijacking redirects metabolites through mechanisms like lactate shuttling and nucleotide theft via tunneling nanotubes and extracellular vesicles while subverting cytokine networks through TGFβ-dependent immunosuppression. Second, bioelectrical hijacking capitalizes on ion gradient alterations via V-ATPase-driven depolarization and intercellular communication through gap junction-transmitted calcium waves. Third, mechanical hijacking involves ECM restructuring through LOXL2-mediated fibrosis and cadherin tension modulation via β-catenin liberation during cellular force competitions. The hijacking of these signals reprograms the genetic and protein landscape of cells within the tumor microenvironment, fostering an environment suitable for tumor survival. Accordingly, therapeutic strategies targeting these vulnerabilities aim to disrupt tumor communication through three primary modalities: chemical interception (e.g., LDHA and MCT1 inhibitors), bioelectrical recalibration (e.g., Kv1.3 activators and TRPV1 antagonists), and mechanical intervention (e.g., LOXL2 antibodies and Piezo1 inhibitors). This “signal hijacking “paradigm recasts cancer as a battle for communicative control within the ecosystem. We thus propose that reestablishing system-wide signaling homeostasis, rather than pursuing pure cytoreduction, represents a fundamental strategy to overcome therapy resistance.</div></div>","PeriodicalId":8782,"journal":{"name":"Biochimica et biophysica acta.

This review highlights the multifaceted roles of S-palmitoylation in shaping the immunological landscape of PDAC. We systematically discuss its involvement in immune checkpoint regulation, T-cell activation, antigen presentation, and the function of myeloid-derived suppressor cells (MDSCs), integrating evidence from both PDAC and other cancer types. Special attention is given to key palmitoylated molecules, including programmed death-ligand 1 (PD-L1), cluster of differentiation 80 (CD80), lymphocyte-specific protein tyrosine kinase (LCK), linker for activation of T cells (LAT), interferon-induced transmembrane proteins (IFITMs), and major histocompatibility complex class I (MHC-I), and their potential roles in the immunosuppressive network of PDAC. Moreover, we explore therapeutic strategies targeting palmitoylation, such as the use of selective palmitoyltransferase inhibitors, the design of palmitoylation-deficient CAR-T cells, and the development of nanotechnology-based delivery platforms.

Data accumulated over the past 26 years have shown that SAG is overexpressed in many types of human cancer tissues with positive correlation of poor patient survival. Functional studies have revealed that SAG is essential for cancer cell growth, and for tumorigenesis induced by oncogene activation and tumor suppressor inactivation in several genetically modified mouse models. Mechanistically, SAG acts as a catalytic subunit of CRL5 as well as CRL1 to ubiquitylate and degrade mainly tumor suppressor substrates, whereas SAG knockdown or knockout causes their accumulation to inhibit the growth and survival of cancer cells, and tumor progression. Thus, SAG E3 is emerging as an attractive anti-cancer target with drug discovery of small molecule inhibitors and PROTAC degraders being currently pursued.
