Kinesin family member 20A (KIF20A), a microtubule-dependent motor protein, shows dysregulated expression across cancers, yet its tumor-type specific functions and value as an anticancer target remain insufficiently clarified. This study integrates multi-omics data from multiple cancer resources to assess KIF20A alterations, pathway involvement, clinical relevance, and immunotherapy potential. Functional experiments in kidney renal clear cell carcinoma (KIRC) demonstrate that KIF20A inhibition suppresses proliferation, migration, invasion, and tumor growth in vivo.

Its expression is dysregulated in various cancers and is closely related to tumor metastasis and patient prognosis. However, its speciﬁc functions indifferent tumor types and the potential as an anticancer target have not been fully elucidated, and a systematic pan-cancer analysis is lacking. Methods: This study integrated multiple cancer database resources and systematically analyzed the multi-omics alterations of KIF20A in different cancers using R software, including gene expression, genomic variation, methylation status, biological pathways, and clinical value. In addition, we evaluated the regulatory role and immunotherapy potential of KIF20A in the tumor microenvironment through various bioinformatics algorithms. Finally, we explored the impact of KIF20A on the biological behaviors of Kidney Renal Clear Cell Carcinoma (KIRC) cells through in vitro and in vivo experiments. Results: KIF20A is localized in the nucleus and participates in the cell cycle process, serving as a core gene for tumor cell growth. It undergoes copy number alterations in various tumors, and its high expression is closely associated with clinical progression, poor prognosis, and activation of classical oncogenic pathways in multiple cancers . Mechanistically, aberrant epigenetic modiﬁcations and mutations in hallmark pathways are signiﬁcant reasons for the dysregulated expression of KIF20A. Furthermore, the expression of KIF20A correlates with immune cell inﬁltration and the expression of immune checkpoint molecules, impacting the efﬁcacy of immunotherapy in various cancers. In vitro experiments have conﬁrmed that interfering with KIF20A expression can effectively inhibit the proliferation, migration, and invasion of KIRC cells. Furthermore, in vivo experimental results indicate that interfering with KIF20A can inhibit tumor growth in nude mice. Frontiers in Immunology 01 [frontiersin.org](frontiersi

FAQs

What is KIF20A and why is it important in cancer?

KIF20A is a microtubule-dependent motor protein involved in cell division and organelle transport. Its expression is dysregulated in multiple cancers and is linked to tumor metastasis and prognosis.

How was KIF20A analyzed in this study?

The study integrated multiple cancer database resources and performed multi-omics analyses of KIF20A, including gene expression, genomic variation, methylation, pathways, and clinical value, using R-based bioinformatics and algorithms.

What biological effects does KIF20A inhibition have in KIRC?

In vitro, interfering with KIF20A suppresses KIRC cell proliferation, migration, and invasion. In vivo, KIF20A interference inhibits tumor growth in nude mice.
