Background And Objective:
Cyclin-dependent protein kinases (CDKs) have been suggested as prospective therapeutic targets because they control processes vital to the survival and growth of cancer cells. However, research on the varied CDK expression profiles and prognostic factors in osteosarcoma is still lacking.
Methods:
The osteosarcoma microRNA (GSE65071) and gene expression profiles were retrieved from the Gene Expression Omnibus (GEO) database (GSE42352). A substantial variation in prognosis was discovered in CDKs using the TARGET database. Cytoscape was used to construct the miRNAs-CDKs network, and functional and pathway enrichment analyses were completed. It was looked at how immune checkpoint genes, m6A-related genes, and CDKs interact.
Results:
In patients with osteosarcoma compared to normal samples, CDK1-5, CDK18, CDK16, and CDK17 gene expression levels were considerably greater, whereas CDK7-9, CDK11B, CDK16, and CDK20 gene expression levels were significantly lower. Patients with osteosarcoma who had low CDK3 and 18 gene levels or high CDK6, 9 gene levels were predicted to have a favorable prognosis and a long-life expectancy. Immune checkpoint genes, m6A-related gene expression, and CDKs expression all showed some connection. Finally, a network of crucial CDKs and miRNAs was constructed.
Conclusion:
According to our research, CDK3, 6, 9, and 18 have been identified as possible therapeutic targets for osteosarcoma, and CDKs may have a role in controlling m6A mutations in tumor cells as well as immune checkpoint regulation.
Insights
Cyclin-dependent protein kinases (CDKs) show varied expression in osteosarcoma, with specific CDKs (3, 6, 9, 18) identified as potential therapeutic targets. These CDKs may influence immune checkpoints and m6A modifications in cancer.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Cyclin-dependent protein kinases (CDKs) are crucial for cancer cell survival and growth, making them promising therapeutic targets.
- Limited research exists on CDK expression profiles and prognostic significance in osteosarcoma.
Purpose of the Study:
- To investigate differential CDK expression in osteosarcoma.
- To identify prognostic biomarkers among CDKs for osteosarcoma patients.
- To explore the relationship between CDKs, microRNAs (miRNAs), immune checkpoints, and m6A-related genes in osteosarcoma.
Main Methods:
- Gene and microRNA expression data for osteosarcoma were analyzed using datasets from the Gene Expression Omnibus (GEO) and TARGET databases.
- A network of miRNAs and CDKs was constructed using Cytoscape.
- Functional and pathway enrichment analyses were performed.
- Interactions between CDKs, immune checkpoint genes, and m6A-related genes were examined.
Main Results:
- CDK1-5, 16-18, and 17 showed significantly higher expression in osteosarcoma compared to normal samples.
- CDK7-9, 11B, 16, and 20 exhibited significantly lower expression in osteosarcoma.
- Low expression of CDK3 and 18, or high expression of CDK6 and 9, correlated with a favorable prognosis and longer survival.
- A significant association was observed between CDK expression, immune checkpoint genes, and m6A-related genes.
Conclusions:
- CDK3, 6, 9, and 18 are identified as potential therapeutic targets for osteosarcoma.
- CDKs play a role in regulating m6A modifications and immune checkpoints in osteosarcoma cells.

M-Cdk Drives Transition Into Mitosis
Cyclin-dependent kinases, or Cdks, work in concert with cyclins to control cell cycle transitions. M-Cdk, a complex of Cdk1 bound to M cyclin, is a well-known example of this coordinated control that drives the transition from the G2 to the M phase.
