Abstract

Insights

Cell cycle G(1)/S checkpoint control is crucial for preventing neoplastic transformation. Failures in this decision-making process can lead to cancer, suggesting new therapeutic targets in cell cycle regulation.

Area of Science:

  • Molecular Biology
  • Cell Biology
  • Genetics

Background:

  • Cell cycle progression involves intricate epigenomic regulation.
  • The G(1) phase and G(1)/S checkpoint are critical for processing transcriptional information before DNA replication.
  • Dysregulation of these processes can lead to neoplastic transformation.

Purpose of the Study:

  • To explore the role of cell cycle phase G(1) and the G(1)/S checkpoint in transcriptional reorientation programs.
  • To investigate the link between cell cycle control and neoplastic transformation.
  • To identify potential new therapeutic strategies for cancer.

Main Methods:

  • Bibliographic database searches (PubMed, Central Medical Library Cologne) were conducted.
  • Keywords included cell cycle, epigenomics, DNA methylation, stem cells, and neoplastic transformation.
  • Literature review focused on G(1) phase, G(1)/S checkpoint, and their relation to gene expression and cancer.

Main Results:

  • Gene transcription and epigenomic surveillance are functionally linked, with G(1) phase processing information for the G(1)/S checkpoint.
  • Transcriptional instability during genomic reorientation can be inherited by daughter cells if the G(1)/S checkpoint fails.
  • Epigenomic deregulation of histone-modifying enzymes may activate oncogenic sequences, contributing to neoplastic transformation.

Conclusions:

  • Failure of the G(1)/S checkpoint decision-making for DNA replication is a significant factor in neoplastic transformation.
  • Further research into the dynamics of G(1) and G(1)/S phases offers potential for novel antineoplastic therapies.

DNA Damage Can Stall the Cell Cycle02:36

DNA 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...

The Cell Cycle Control System01:28

The Cell Cycle Control System

The cell cycle regulation directs how a cell proceeds from one phase to the next and begins mitosis. The cell cycle control system includes intracellular regulatory molecules and external triggers. They provide "stop" or "advance" signals and operate at specific cell cycle stages termed checkpoints to ensure that a particular process is completed before the cell advances to the next phase.
Cyclins and cyclin-dependent kinases (Cdks) are the primary cell cycle regulators and function at the cell...
The Cell Cycle Control System02:11

The Cell Cycle Control System

The cell cycle is an organized set of events that leads the cell to divide into two daughter cells, each containing chromosomes identical to the parent cell. It is the cell cycle that leads to the formation of an entire organism from a single-cell zygote. Besides, cell division also functions in the renewal or repair of tissues in adult multicellular eukaryotes. For example, in the bone marrow, the stem cells divide to form new blood cells. Although essential for several functions, cell...
S-Cdk Initiates DNA Replication02:38

S-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.
