Long Non-Coding RNA VPS9D1-AS1 in Human Cancer: Functions, Mechanisms, and Clinical Utility.

Introduction: VPS9 domain-containing 1 antisense RNA 1 (VPS9D1-AS1), also known as c-Mycupregulated lncRNA (MYU) and FAK-interacting and stabilizing lncRNA (FAISL), is a novel long non-coding RNA (lncRNA) located at the human chromosome 16q24.3 locus. It has been reported to be highly expressed in various human cancers and associated with poor clinical pathological features and unfavorable prognosis in eight of the malignant tumors.

Methods: A comprehensive literature search was conducted using PubMed, Web of Science, and Google Scholar databases to identify relevant articles on "VPS9D1-AS1", "MYU", or "FAISL". Only peer-reviewed publications were included, and articles related to oncology were specifically collected.

Results: Mechanistically, VPS9D1-AS1 serves as a key regulator in four molecular models: signal, scaffold, guide, and decoy. These functions allow it to regulate the expression of target genes and activation of signaling pathways, thereby influencing the malignant phenotype of tumors.

Discussion: The diverse molecular mechanisms of VPS9D1-AS1 highlight its significant role in the development and progression of various cancers. Its ability to act as a signal, scaffold, guide, and decoy suggests that it can influence multiple aspects of tumor biology, including proliferation, invasion, and metastasis.

Conclusion: VPS9D1-AS1 plays a significant role in the development and progression of various cancers through its diverse molecular mechanisms. Further research on VPS9D1-AS1 may provide valuable insights, which may facilitate the development of new diagnostic and therapeutic strategies for cancer.
