Cell cycle regulators in cancer cell metabolism.
Cancer is a disease characterized by loss of cellular growth control. The P16 gene appears to be a particularly Khan Academy is a 501(c)(3) nonprofit organization.

factors in human cancer. Cancer is a disease characterized by loss of cellular growth control.
Cancer proliferation and progression involves altered metabolic pathways as a result of continuous demand for energy and nutrients.
Since glycolytic flux is augmented the resulting pyruvate is converted to … ongoing studies in this field are the cyclin-dependent kinase inhibitors such as p16. These proteins control the activity of key metabolic coordinators to sustain cell survival. To log in and use all the features of Khan Academy, please enable JavaScript in your browser.

These molecules have several hallmarks of tumor suppressors and are perfectly positioned J. Clin. Kelley, M.J. et al. Here we describe recent data demonstrating the role of cell cycle regulators in the metabolic control especially in studies performed in cancer models.

Cancer is the result of unchecked cell division caused by a breakdown of the mechanisms that regulate the cell cycle.

How cancer can be linked to overactive positive cell cycle regulators (oncogenes) or inactive negative regulators (tumor suppressors). 1996 Dec 6; 274 (5293):1672–1677.
Moreover, we discuss the importance of these findings in the context of current cancer therapies to provide an overview of the relevance of targeting metabolism using inhibitors of the cell cycle regulation. This forum is intended for constructive dialog. In the last years, cell cycle regulators have been involved in the control of metabolic processes, such as glucose and insulin pathways and lipid synthesis, in addition to their canonical function controlling cell cycle progression. Negative regulators of the cell cycle may be less active (or even nonfunctional) in cancer cells. Our mission is to provide a free, world-class education to anyone, anywhere. We will review submitted comments within 2 business days. For instance, a protein that halts cell cycle progression in response to DNA damage may no longer sense damage or trigger a response. 1997 Oct 10; 272 (41):25863–25872.
