Key Protein Can Help Cells Or Cause Cancer
Date: 13.7.2009
A Purdue University scientist has discovered a key process in **cell growth** that can lead to the formation of **tumors**.
Xiaoqi Liu, an assistant professor of biochemistry, found that an overabundance of the polo-like kinase 1, or Plk1, molecule during cell growth, as well as a shortage of the **p53 molecule**, will lead to tumor formation. Studies in Liu's laboratory showed that the Plk1 molecule indirectly attacks p53 in a process called ubiquitination.
