ABSTRACT Integrated approaches that help understand how tumors, as immune-surveilled ecosystems, respond to chemotherapy are crucial for developing effective antitumor treatments. We previously showed, in immunodeficient context, antimitotic induced cGAS/STING pathway amplifying response through a paracrine IFN-1 secretome. herein studied tumor progression and treatment using an immunocompetent murine model. scRNAseq analysis revealed paclitaxel altered cell phenotypes, favoring cells with gene expression signature indicative of active NF-κB secretory phenotype. Treatment coincidently reduced IFN-I during progression. The resulting shift correlated neutrophil recruitment the tumor, particularly CXCR2+ neutrophils, thereby contributing immunosuppressive microenvironment. Pharmacological inhibition CXCR2 receptor by navarixin reactivated immunity, enhancing NK infiltration cytotoxicity. Navarixin combination significantly volume metastasis. Targeting NF-κB-driven phenotype, particular modulation, holds promise improving TNBC outcomes.

Cell death mechanisms are broadly classified into accidental cell (ACD) and regulated (RCD). ACD such as necrosis, is an uncontrolled, process, while RCD tightly by specific signaling pathways molecular mechanisms. Tumor cells characterized their ability to evade sustain uncontrolled proliferation. The failure of programmed a key contributor tumor initiation, progression, resistance cancer therapies. Traditionally, research has focused primarily on apoptosis the dominant form in cancer. However, emerging evidence highlights importance other non-apoptotic forms RCD, pyroptosis, ferroptosis, necroptosis, parthanatos, tumorigenesis treatment response. These gaining attention for potential roles overcoming therapy resistance. In this review, we will discuss recent advances study malignant tumors explore therapeutic implications, offering insights new targets strategies.

Background: Radiotherapy is a key treatment for cancer, effectively controlling local tumor growth through DNA damage that induces senescence or apoptosis in cancer cells. However, radiotherapy can trigger complex cellular reactions, such as cell senescence, which characterized by irreversible cycle arrest and the secretion of pro-inflammatory factors known senescent-associated secretory phenotype (SASP). Methods: This study investigates regulatory role ALDH1A3, enzyme implicated metabolism resistance, induction SASP. Using vitro models, we demonstrate ALDH1A3 knockdown accelerates senescent-like while regulating SASP cGAS-STING immune response pathway. Results: Our results indicate promotes it reduces via inhibition pathway, potentially mitigating SASP-related progression. Conclusions: These findings provide insights into molecular mechanisms underlying prostate suggest could be potential therapeutic target to enhance efficacy adverse effects
