Insights

New cancer drugs targeting cell cycle kinases (Cdk) and chromatin deacetylases (HDAC) show promising clinical efficacy. These mechanism-based therapies offer potential improvements over traditional chemotherapy.

Area of Science:

  • Oncology
  • Molecular Biology
  • Pharmacology

Background:

  • Tumour cells exhibit uncontrolled proliferation.
  • Recent discoveries link cell cycle regulation with chromatin and gene expression.
  • Existing chemotherapeutics have limitations.

Purpose of the Study:

  • To explore novel therapeutic strategies for cancer.
  • To investigate the role of Cdk and HDAC inhibitors in cancer treatment.

Main Methods:

  • Review of recent advances in cell cycle and chromatin control research.
  • Analysis of small-molecule drugs targeting cyclin-dependent kinases (Cdk) and histone deacetylases (HDAC).
  • Examination of emerging clinical data on Cdk and HDAC inhibitors.

Main Results:

  • Small-molecule inhibitors targeting Cdk and HDAC are in clinical studies.
  • These targeted therapies demonstrate emerging clinical efficacy.
  • Mechanism-based approaches integrate cell growth, division, and gene expression control.

Conclusions:

Inhibition of Cdk Activity02:34

Inhibition of Cdk Activity

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

What is the Cell Cycle?

The cell cycle refers to the sequence of events occurring throughout a typical cell’s life. In eukaryotic cells, the somatic cell cycle has two stages: the interphase and the mitotic phase. During interphase, the cell grows, performs its basic metabolic functions, copies its DNA, and prepares for mitotic cell division. Then, during mitosis and cytokinesis, the cell divides its nuclear and cytoplasmic materials, respectively. This generates two daughter cells that are identical to the original...

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
