Abstract

Homeobox (HOX) C9, a member of the HOX family, is an important transcription factor, and it plays a significant role in various biological processes. This family of genes is highly valued for their essential roles in establishing and maintaining the body axis during embryonic development and adult tissues. Further, HOXC9 plays a central role in neuronal differentiation, angiogenesis, and adipose distribution, which are essential for the development of the nervous system, maturation of tissues and organs, and maintenance of energy balance and metabolic health. Recent research has found that abnormal HOXC9 expression is closely associated with the development and progression of various tumor types. The HOXC9 expression level can be an indicator of tumor prognosis. Therefore, elucidating the association between HOXC9 expression and its regulatory mechanisms and tumorigenesis can provide novel insights on the diagnosis and treatment of patients with cancer.

Keywords: Homeobox C9; Proliferation; Invasion; Malignant tumor; Molecular mechanism

Core Tip: This paper discusses the association between abnormal homeobox (HOX) C9 expression and the occurrence and progression of various tumors, the impact of HOXC9 on the clinical pathological characteristics and prognosis of cancer patients, the role of HOXC9 in central nervous system tumors, breast cancer, bladder cancer, gastric cancer, colon cancer, non-small cell lung cancer, and thyroid papillary carcinoma, and the molecular mechanisms underlying the biological functions of HOXC9, including its interaction with other proteins and its regulation through DNA methylation.
