Mechanisms and Therapeutic Implications of EZH2 in Nasal Diseases

Enhancer of zeste homolog 2 (EZH2), a protein encoded by the EZH2 gene, is a crucial subunit in polycomb repressive complex 2. EZH2 controls the transcription of genes critical for cell proliferation, differentiation, amplification, and function through both methylated and unmethylated functions. EZH2 is considered to be a transcriptional suppressor protein when it controls histone methylation. Its dysregulation is related to a variety of cancers, with significant evidence showing its role in prostate cancer and breast cancer. EZH2 is also thought to be involved in the differentiation and function of immune cells. Ongoing research on EZH2 has revealed the correlation between inflammatory nasal diseases, the occurrence and development of nasal sinus tumors, and EZH2. This article aimed to review the research progress on the role of EZH2 in nasal diseases and explore the possibility of future EZH2-targeted therapies for nasal diseases.
