Visualization of DNA Replication in the Vertebrate Model System DT40 using the DNA Fiber Technique
Published on: October 27, 2011
Summary
Cancer may arise from mobile genetic elements acting as replicons, potentially reverting eukaryotic replication to a prokaryotic state. These elements might transform fixed origins, driving a form of "re-evolution" in cancer development.
Area of Science:
- Genetics
- Molecular Biology
- Cancer Research
Background:
- Movable genetic elements are implicated in various cellular processes.
- Understanding the role of genetic elements in cancer is crucial for developing new therapies.
Purpose of the Study:
- To investigate the potential role of movable genetic elements as replicons or replicative origins in cancer.
- To explore the hypothesis that cancer involves a reversion from eukaryotic to prokaryotic replication mechanisms.
Main Methods:
- The study is based on theoretical assumptions and existing evidence regarding genetic elements.
- Analysis of potential interactions between mobile Alu-origins and fixed chromosomal origins.
Main Results:
- Mobile Alu-origins are proposed as candidates for precursors of chromosomal insertions.
- These elements may interact with and modify fixed chromosomal origins, leading to "procaryotic-like" replication.
Conclusions:
- Cancer is hypothesized to result from a rapid "re-evolution" of replication units from eukaryotic to prokaryotic forms.
- Movable genetic elements play a key role in this proposed cancer mechanism.

02:31Chromosome Replication
Before a cell can divide, it must accurately replicate all of its chromosomes, including the DNA and its associated histone and non-histone proteins. This process begins at numerous origins of replication during the S phase of the cell cycle in each of a cell’s chromosomes simultaneously. Certain nucleotides can act as origins of replication, but these sequences are not well defined - especially in complex, multi-cellular, eukaryotic species. The length of DNA that spans an origin of...
02:38S-Cdk Initiates DNA Replication
The cell cycle is a series of events leading to DNA duplication followed by the division of cell content to form two daughter cells. The cell cycle progresses in four stages—the cell increases in size (gap 1 or G1-phase), duplicates its DNA (synthesis or S-phase), prepares to divide (gap 2 or G2-phase), and divides (mitosis or M-phase).
Two states at the origin of replication
In eukaryotes, the initiation of replication occurs at many sites on the chromosomes, called the origins of replication.

02:21Cancers Originate from Somatic Mutations in a Single Cell
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...
01:51Mechanisms of Retrovirus-induced Cancers
Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...
