SOCS3: An Immunological Biomarker Offering Potential Therapeutic Targets for Malignant Tumors.

Suppressor of Cytokine Signaling 3 (SOCS3) is a critical regulator of cytokine signaling, primarily acting through the Janus Kinase (JAK)/Signal Transducer and Activator of Transcription (STAT) pathway. It plays a significant role in the development and progression of various malignancies. Abnormal expression of SOCS3 in cancer cells is linked to dysregulated cell growth, migration, and apoptosis, driven by cytokines and hormones. This aberrant expression makes SOCS3 a potential biomarker for tumor diagnosis, prognosis, and gene therapy. Targeting SOCS3 may offer innovative strategies for cancer treatment. This review provides a comprehensive overview of SOCS3's molecular structure, its biological functions in tumors, underlying molecular mechanisms, and therapeutic strategies targeting SOCS3.
