Summary
Cisplatin damages DNA, leading to cell cycle arrest in the G2 phase before cell death. This programmed cell death pathway may be shared by other anticancer drugs.
Area of Science:
- Molecular Biology
- Cell Biology
- Pharmacology
Background:
- The anticancer drug cisplatin interacts with DNA to induce cell death.
- Cell cycle progression influences sensitivity to cisplatin, but DNA synthesis inhibition is not the sole critical factor.
Purpose of the Study:
- To investigate the cell cycle effects and cell death mechanisms of cisplatin.
- To explore the potential shared pathways of cell death induced by various anticancer drugs.
Main Methods:
- Analysis of cell cycle progression in response to cisplatin.
- Observation of cellular morphological changes and DNA endonuclease activation.
- Comparison of cisplatin effects with other anticancer agents.
Main Results:
- Lethally damaged cells can arrest in the G2 phase for extended periods before death.
- Cisplatin-induced cell death exhibits features of apoptosis, including chromatin condensation and endonuclease activation.
- Phenotypic effects of cisplatin are similar to those of other anticancer drugs.
Conclusions:
- Cisplatin's mechanism involves DNA damage and subsequent G2 cell cycle arrest, preceding cell death.
- Cisplatin-induced cell death shares characteristics with apoptosis.
- A common signal transduction pathway may mediate cell death for multiple anticancer drugs.

02:36DNA Damage can Stall the Cell Cycle
In response to DNA damage, cells can pause the cell cycle to assess and repair the breaks. However, the cell must check the DNA at certain critical stages during the cell cycle. If the cell cycle pauses before DNA replication, the cells will contain twice the amount of DNA. On the other hand, if cells arrest after DNA replication but before mitosis, they will contain four times the normal amount of DNA. With a host of specialized proteins at their disposal,cells must use the right protein at...
01:30Overview of Cell Death
Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the 20th century...

01:17The Extrinsic Apoptotic Pathway
The extrinsic apoptotic pathway is initiated when extracellular death-inducing signals, such as specific cytokines, activate the death receptors expressed on the cell surface. The immune cells involved in this pathway are natural killer cells (NK cells) and cytotoxic T-lymphocytes. NK cells are critical in innate immune response, while cytotoxic T-lymphocytes are associated with adaptive immune response. These cells recognize specific receptors expressed on the altered cells and activate...
01:31The Intrinsic Apoptotic Pathway
Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...

01:22Cellular Injury V: Apoptosis and Autophagy
Cells respond to damage and stress through highly coordinated processes that decide whether they survive or undergo controlled self-destruction. Two major pathways involved in this regulation are apoptosis, a type of programmed cell death, and autophagy, a survival mechanism that helps cells adapt to adverse conditions.ApoptosisApoptosis removes aged or injured cells to maintain tissue balance. During this process, the cell shrinks, chromatin condenses and fragments, and membrane-bound...
