Deregulation of the cell cycle underlies the aberrant cell proliferation that characterizes cancer and loss of cell cycle checkpoint control promotes genetic instability. During the past two decades, cancer genetics has shown that hyperactivating mutations in growth signalling networks, coupled to loss of function of tumour suppressor proteins Learn how the cell cycle regulates cell growth, division, and DNA replication, and how errors in the cycle can lead to cancer. Find out how chemotherapy, radiation, and targeted therapies affect the cell cycle and treat cancer cells.
The cell cycle and cancer Biology Diagrams
Superficially, the connection between the cell cycle and cancer is obvious: cell cycle machinery controls cell proliferation, and cancer is a disease of inappropriate cell proliferation. Fundamentally, all cancers permit the existence of too many cells. However, this cell number excess is linked in a vicious cycle with a reduction in Cancer is a group of diseases in which cells divide continuously and excessively. Cell division is tightly regulated by multiple evolutionarily conserved cell cycle control mechanisms, to ensure the production of two genetically identical cells. Cell cycle checkpoints operate as DNA surveillance mec โฆ Cancer is the result of unchecked cell division caused by a breakdown of the mechanisms that regulate the cell cycle. The loss of control begins with a change in the DNA sequence of a gene that codes for one of the regulatory molecules.
In this article we will discuss about the Cell Cycle and Cancer:- 1. Introduction to Cell Cycle 2. Regulation of the Cell Cycle 3. Regulators 4. Growth Factors and the D-Type Cyclins 5. Inhibitors 6. Involvement of Oncogenes and Anti-oncogenes. Contents: Introduction to Cell Cycle Regulation of the Cell Cycle Regulators of Cell Cycle Progression Growth Factors and the D-Type Cyclins Inhibitors Most cells in the body go through a cycle of life in which their genetic information is retained, fixed, and passed down to daughter cells through a highly coordinated and regulated process. However, during this cell cycle, there are many situations where mistakes are made by the cycle or by a regulating system that causes the cell to proliferate uncontrollably, leading to cancer.
