Mitogens and the Cell Cycle

8.3K
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...

Molecular Factors Affecting Cell Division

4.0K
Several external and internal factors influence the initiation and inhibition of cell division. For instance, the death of nearby cells or the release of human growth hormone (hGH) promotes cell division. In contrast, lack of hGH or crowding of cells can inhibit cell division.
Several proteins function as internal regulators to ensure each cell cycle stage is completed faithfully before proceeding to the next. Regulator molecules may act directly or influence the activity or production of other...

Negative Regulator Molecules

38.8K
Positive regulators allow a cell to advance through cell cycle checkpoints. Negative regulators have an equally important role as they terminate a cell’s progression through the cell cycle—or pause it—until the cell meets specific criteria.

Cells Coordinate Growth and Proliferation02:36

Cells Coordinate Growth and Proliferation

5.3K
Cell size is a significant factor impacting cellular design, function, and fitness. There exists some internal coordination by which cells double their masses before division, thus, achieving homeostasis. Coordination between cell growth and proliferation depends on the checkpoints in between cell cycle phases. Loss of coordination or failure in the checkpoint mechanism can drive the cell to uncontrolled growth and loss of cellular function. Like dividing cells that coordinate cellular growth,...

Summary

Researchers developed a new method to grow tumorous cells from the nematode Caenorhabditis elegans in vitro. They found that bacterial folates stimulate cell proliferation, separate from their vitamin functions.

Area of Science:

  • Developmental biology
  • Cell biology
  • Microbiology

Background:

  • Tumorous cell proliferation is a complex process.
  • Caenorhabditis elegans is a model organism for studying development and disease.
  • Folates are essential vitamins with known biological roles.

Purpose of the Study:

  • To develop a novel in vitro method for culturing tumorous C. elegans germ cells.
  • To investigate signaling pathways that regulate cell proliferation in C. elegans.
  • To identify novel roles for bacterial folates in cellular processes.

Main Methods:

  • Establishment of an in vitro proliferative cell line from tumorous C. elegans germ cells.
  • Utilizing a novel cell culture technique.
  • Investigating the effects of bacterial folates on cell proliferation.
