Special Issue Information

Dear Colleagues,

Since the identification of oncogenic signaling pathways and growth factor-driven networks in the late twentieth century, our understanding of cell signaling in cancer has advanced remarkably. Cell signaling is now recognized as a central determinant of tumor initiation, progression, therapeutic response and resistance. Rather than acting as linear and isolated cascades, signaling pathways in cancer operate as highly dynamic, interconnected networks that adapt to genetic alterations, microenvironmental cues and therapeutic pressure.

Dysregulated signal transduction governs virtually all hallmarks of cancer, influencing proliferation, survival, metabolic reprogramming, immune evasion and cellular plasticity. Importantly, therapeutic interventions, including targeted therapies, immunotherapies and emerging gene-based approaches, exert their effects by modulating these signaling networks, often triggering compensatory or adaptive signaling responses that limit long-term efficacy. Consequently, understanding how cancer therapies reshape intracellular and intercellular signaling has become essential for the development of durable and personalized treatment strategies.

This Special Issue, Cell Signaling of Cancer Therapy, offers an Open Access forum aimed at bringing together original research and review articles addressing the expanding field of cell signaling in cancer therapy. We welcome contributions covering signaling pathway regulation, therapy-induced signaling adaptation, mechanisms of drug resistance, and crosstalk between cancer cells and the tumor microenvironment. Studies exploring gene therapy, RNA-based interventions and genome-editing strategies that target or reprogram oncogenic signaling networks are particularly encouraged. We hope to provide a stimulating resource for researchers investigating how signaling biology can be harnessed to improve cancer treatment outcomes.

The tumor microenvironment, including extracellular pH (pHe), has emerged as a key regulator of tumor cellular function. Although extracellular acidification sensing and function are well established, the effect of extracellular alkalinization on cellular functioning remains unclear. Here, we report that transient receptor potential ankyrin 1 (TRPA1) functions as an alkaline sensor and mediator of cell death in melanoma cells. Exposure to alkaline pHe (8.1) or allyl isothiocyanate (AITC), a TRPA1 agonist, significantly reduced melanoma cell viability. We found that cell death was propidium iodide-positive and annexin V-negative, suggesting that pHe or AITC treatment induced necrosis rather than apoptosis. TRPA1 activation induced sustained Ca2+ influx, which was suppressed by either extracellular Ca2+ removal or treatment with the TRPA1 inhibitor, HC-030031, both of which attenuated cell death. Pharmacological screening has identified phosphatidylcholine-specific phospholipase D1 (PLD1) as a positive regulator of cell death. We confirmed that transfection with PLD1 siRNA significantly reduced AITC-induced cell death, whereas PLD2, PLD3, and NAPE-PLD siRNAs had no effect. These observations suggest that the vulnerability of melanoma cells to alkaline pHe is mediated by activation of the TRPA1-PLD1 axis. Thus, TRPA1 and PLD1 are potential targets for therapeutic intervention in melanoma. Full article
