CDC6 exhibits oncogenic characteristics and plays a significant role in tumor grading and prognosis prediction. Analysis of The Cancer Genome Atlas (TCGA) data shows that the CDC6 gene is significantly overexpressed in 97.22% (70\/72) of paired clinical samples in ccRCC tissues compared to adjacent normal tissues. Consistent with this, elevated CDC6 protein levels were observed across all four paired tumor tissues examined. Functional experiments further confirm that CDC6 expression levels directly influence cellular proliferation, as its knockdown suppresses cell viability by ~60% in CCK-8 assays (p &lt; 0.001) and reduces EdU incorporation by ~50%. Mechanistically, in tumor tissues, CDC6 transcription is epigenetically regulated by histone acetylation and methylation, which in turn modulates downstream effectors, e.g., the exosome complex protein EXOSC5. Our findings indicate that in ccRCC, increased histone H3K4 trimethylation near the CDC6 transcriptional start site enhances its expression. The methyltransferase SETD1A may act as a potential upstream regulator mediating the transcriptional activation of CDC6, thereby driving tumor progression through the regulation of EXOSC5. We have further investigated the relationship between the CDC6-associated gene network and tumor development and clarified the diagnostic and prognostic relevance of the SETD1A\u2013CDC6\u2013EXOSC5 axis in ccRCC. The outcomes of this research are expected to provide novel insights into the pathogenesis of renal cell carcinoma and establish a theoretical foundation for new diagnostic strategies.<\/jats:p>","DOI":"10.3390\/ijms27135657","type":"journal-article","created":{"date-parts":[[2026,6,24]],"date-time":"2026-06-24T03:09:17Z","timestamp":1782270557000},"page":"5657","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["H3K4me3 and H3K27ac Promote ccRCC Proliferation Through the CDC6-EXOSC5 Axis"],"prefix":"10.3390","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-0846-4432","authenticated-orcid":false,"given":"Peng","family":"Cui","sequence":"first","affiliation":[{"name":"Precision Medicine Institute, Peking University Shenzhen Hospital, Shenzhen 518036, China"},{"name":"Intervention and Cell Therapy Center, Peking University Shenzhen Hospital, Shenzhen 518036, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan","family":"Luo","sequence":"additional","affiliation":[{"name":"Precision Medicine Institute, Peking University Shenzhen Hospital, Shenzhen 518036, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ping","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Hematology, Peking University Shenzhen Hospital, Shenzhen 518036, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiongye","family":"Dong","sequence":"additional","affiliation":[{"name":"Precision Medicine Institute, Peking University Shenzhen Hospital, Shenzhen 518036, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiangling","family":"Chen","sequence":"additional","affiliation":[{"name":"Precision Medicine Institute, Peking University Shenzhen Hospital, Shenzhen 518036, China"},{"name":"Department of Urology, Peking University Shenzhen Hospital, Shenzhen 518036, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,6,23]]},"reference":[{"key":"ref_1","first-page":"17","article-title":"Cancer statistics, 2023","volume":"73","author":"Siegel","year":"2023","journal-title":"CA Cancer J.
