Abstract:
The cell cycle is the cascade of events that allows a growing cell to duplicate all its components and split into two daughter cells. Cell cycle progression is mediated by the activation of a highly conserved family of protein kinases, the cyclin-dependent kinases (CDKs). CDKs are also regulated by related proteins called cdk inhibitors grouped into two families: the INK4 inhibitors (p16, p15, p19, and p18) and the Cip/Kip inhibitors (p21, p27, and p53). Several studies report the importance of cell-cycle proteins in the pathogenesis and the prognosis of lung cancer. This paper will review the most recent data from the literature about the regulation of cell cycle. Finally, based essentially on the data generated in our laboratory, the expression, the diagnostic, and prognostic significance of cell-cycle molecules in lung cancer will be examined.
Insights
This review examines cell cycle regulation by cyclin-dependent kinases (CDKs) and inhibitors, focusing on their role in lung cancer pathogenesis and prognosis.
Area of Science:
- Molecular Biology
- Cell Biology
- Oncology
Background:
- The cell cycle is a fundamental biological process essential for cell growth and division.
- Cyclin-dependent kinases (CDKs) and their inhibitors (CDKIs) are key regulators of cell cycle progression.
- Dysregulation of cell cycle proteins is implicated in various cancers, including lung cancer.
Purpose of the Study:
- To review recent literature on cell cycle regulation mechanisms.
- To examine the expression, diagnostic, and prognostic significance of cell-cycle molecules in lung cancer.
Main Methods:
- Literature review of cell cycle regulation.
- Analysis of laboratory data on cell-cycle molecules in lung cancer.
Main Results:
- Cell cycle progression is tightly controlled by CDK and CDKI families.
- Altered expression of cell cycle proteins is observed in lung cancer.
- Specific cell cycle molecules show potential as diagnostic and prognostic markers for lung cancer.
Conclusions:
- Understanding cell cycle regulation is crucial for cancer research.
- Cell cycle proteins hold significant potential as biomarkers in lung cancer diagnosis and prognosis.

When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
