Abstract
Background: The smooth muscle α‑actin 2‑antisense 1 (ACTA2-AS1), also known as ZXF1, is an emerging cancer-associated long non-coding RNA (lncRNA) that has garnered significant attention in recent years. ACTA2-AS1 is situated on human chromosome 10 at location 10q23.31, comprising five exons and a single transcript. The aberrant expression of ACTA2-AS1 has been noted in 10 malignant tumors, correlating significantly with unfavorable clinicopathological characteristics and poor patient prognosis.
Objective: This review encapsulates recent progress in ACTA2-AS1 research, examining its expression profile, biological functions, molecular mechanisms, and anticipated influence on cancer diagnosis, treatment, and prognosis, emphasizing its potential as a novel therapeutic target based on lncRNA and its prognostic utility as a biomarker.
Methods: Based on a comprehensive search of the PubMed database for the biological function of lncRNA ACTA2-AS1 in malignant tumors, the current research is systematically summarized and critically analyzed.
Results: ACTA2-AS1 plays a complex role in various biological processes in tumor cells, encompassing proliferation, apoptosis, and cell cycle arrest. It also contributes to migration, invasion, epithelial-mesenchymal transition (EMT), and drug resistance. Mechanistically, ACTA2-AS1 influences oncogenic or tumor-suppressive effects via a complex regulatory network. It can adsorb specific 5 miRNAs as competitive endogenous RNAs (ceRNAs), thereby mitigating the suppression of downstream mRNA targets implicated in tumorigenesis (e.g., SOX7, KLF9, CXCL2, BCL2L11, etc.) and modulating their downstream signaling pathways (e.g., Wnt5a/PKC, SMAD3, mTOR, etc.), demonstrating a broad spectrum of dual roles in carcinogenesis and tumor suppression.
Conclusion: ACTA2-AS1 is a promising biomarker and molecular target for the treatment of cancer.
