Dynamic Evolution of the Tumor Immune Microenvironment in Malignant Tumors and Emerging Therapeutic Paradigms

MedComm, Volume 6, Issue 12, December 2025.
Cancer is a complex tumor system consisting of tumor cells, immune effector cells, and all the matrix components. The intricate interactions among cells and molecular signaling pathways in this microenvironment jointly drive tumor growth, invasion, and metastasis, and significantly influence the efficacy of cancer treatment. Meanwhile, the treatment of

Protein O‐GlcNAcylation in Health and Diseases

MedComm, Volume 6, Issue 12, December 2025.
We first introduced the beneficial effects of normal protein O‐GlcNAcylation on health, impacting biological processes such as gene expression, cell cycle progression, metabolism, and signal transduction. Next, we described the role of abnormal protein O‐GlcNAcylation in the development and progression of diseases, including neurodegenerative diseases,

Air Pollution‐Induced Epigenetic Regulation in Respiratory Diseases: Mechanisms, Dysregulation, and Therapeutic Opportunities

MedComm – Future Medicine, Volume 4, Issue 4, December 2025.
Air pollution, a major global health hazard, contributes to asthma, chronic obstructive pulmonary disease, pulmonary fibrosis, and lung cancer via four core epigenetic pathways (DNA/RNA methylation, noncoding RNAs, and histone modifications), shaping gene expression and driving disease pathogenesis.

Targeting Metabolic Reprogramming in Tumor: From Mechanisms to Precision Immunotherapies

MedComm – Oncology, Volume 4, Issue 4, December 2025.
Cancer metabolic reprogramming is a key hallmark of tumorigenesis and antitumor immunity. It boosts tumor progression by enhancing cancer cell fitness in hostile microenvironments and facilitates immune evasion by evading natural and therapy‐driven antitumor immune responses.
