Targeting the cell-cycle machinery for cancer therapy

Area of Science:

• Oncology
• Molecular Biology
• Cell Biology

Background:

• The cell cycle is crucial for genomic stability during cell proliferation.
• Dysregulation of cell cycle checkpoints and proteogenomic oscillations can lead to oncogenic transformation.
• The cell cycle is a key target in precision oncology due to its role in cancer development.

Purpose of the Study:

• To review emerging mechanistic insights into cell cycle dysregulation in tumorigenesis.
• To highlight novel therapeutic strategies targeting cell cycle machinery.
• To discuss the role of proteomic and post-translational dynamics in cancer therapy.

Main Methods:

• Review of recent advances in cell cycle research.
• Analysis of proteomic and post-translational modifications in cell cycle regulation.
• Exploration of emerging therapeutic strategies like targeted protein degradation and synthetic lethality.

Main Results:

• Aberrant cell cycle phase transitions, orchestrated by proteomic and post-translational dynamics, are disrupted in cancers.
• Targeting CDK4/6 is a cornerstone therapy, but resistance is a significant challenge.
• Emerging strategies and biomarker-driven approaches enhance therapeutic efficacy against cell cycle vulnerabilities.

Conclusions:

• Understanding cell cycle aberrations provides critical insights into tumorigenesis.
• Novel therapeutics targeting cell cycle machinery hold promise for effective cancer treatment.
• Precision medicine approaches exploiting cell cycle vulnerabilities are transforming cancer therapy.
