Abstract:
Despite the development of targeted therapies and novel inhibitors, cancer remains an undefeated disease. Resistance mechanisms arise quickly and alternative treatment options are urgently required, which may be partially met by drug combinations. Protein kinases as signaling switchboards are frequently deregulated in cancer and signify vulnerable nodes and potential therapeutic targets. We here focus on the cell cycle kinase CDK6 and on the MAPK pathway and on their interplay. We also provide an overview on clinical studies examining the effects of combinational treatments currently explored for several cancer types.
Insights
Cancer treatment requires new strategies due to resistance. Combining targeted therapies, like those inhibiting cyclin-dependent kinase 6 (CDK6) and the MAPK pathway, shows promise for overcoming this challenge.
Area of Science:
- Oncology
- Molecular Biology
- Pharmacology
Background:
- Cancer remains a significant global health challenge, often developing resistance to existing targeted therapies and inhibitors.
- Protein kinases are crucial signaling regulators frequently dysregulated in cancer, representing key therapeutic targets.
- The urgent need for alternative treatment options necessitates exploring novel therapeutic strategies, including drug combinations.
Purpose of the Study:
- To investigate the interplay between the cell cycle kinase CDK6 and the MAPK pathway in cancer.
- To provide an overview of clinical studies evaluating combination treatments involving CDK6 and MAPK pathway inhibitors.
- To highlight the potential of drug combinations as a strategy to overcome cancer resistance.
Main Methods:
- Literature review of preclinical and clinical studies.
- Analysis of the roles of CDK6 and the MAPK pathway in cancer signaling.
- Synthesis of data from clinical trials investigating combination therapies.
Main Results:
- CDK6 and the MAPK pathway are frequently implicated in cancer development and progression.
- Combinational targeting of CDK6 and MAPK pathway components demonstrates potential in preclinical models.
- Clinical studies are exploring various combinations for diverse cancer types, with preliminary data suggesting efficacy.
Conclusions:
- Targeting CDK6 and the MAPK pathway, particularly in combination, offers a promising avenue for overcoming cancer treatment resistance.
- Further clinical investigation is warranted to optimize drug combinations and establish their role in cancer therapy.
- Drug combinations represent a vital strategy to address the limitations of monotherapies in combating cancer.

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.
