For instance, cancer cells gain the ability to migrate to other parts of the body, a process called metastasis, and to promote growth of new blood vessels, a process called angiogenesis (which gives tumor cells a source of oxygen and nutrients).
10 de sept. de 2021 · This Review discusses our current understanding of cell cycle regulation, the functions of cell cycle checkpoints and how disruption of these finely tuned mechanisms is associated with...
17 de jun. de 2003 · CELL CYCLE AND CANCER. In cancer, there are fundamental alterations in the genetic control of cell division, resulting in an unrestrained cell proliferation. Mutations mainly occur in two classes of genes: proto‐oncogenes and tumour suppressor genes.
1 de abr. de 1997 · By what molecular pathway does loss of cell cycle regulation in an organism lead to cancer? What genetic changes can cooperate to accomplish the cancer cell’s escape from the normal balance of cell growth?
14 de ago. de 2023 · Overall, the cell cycle has many regulatory steps that are crucial to maintaining homeostasis inside of the cells during the replication of DNA and the division of cells. Mutation inside specific genes can lead to the loss of balance inside the cells, thus resulting in cancer growth.
Checkpoints can delay cell cycle progression or, in response to irreparable DNA damage, induce cell cycle exit or cell death. Cancer-associated mutations that perturb cell cycle control allow continuous cell division chiefly by compromising the ability of cells to exit the cell cycle.
Abstract. Aberrancy in cell cycle progression is one of the fundamental mechanisms underlying tumorigenesis, making regulators of the cell cycle machinery rational anticancer therapeutic targets. A growing body of evidence indicates that the cell cycle regulatory pathway integrates into other hallmarks of cancer, including metabolism remodeling ...
