Purdue University scientists believe they have found an effective target for killing late-stage, metastatic prostate cancer cells. Xiaoqi Liu, an assistant professor of biochemistry and member of Purdue's Center for Cancer Research, and graduate student Shawn Liu are focusing on the function of a gene called Polo-like kinase (Plk1), a critical regulator of the cell cycle. Plk1 is also an oncogene, which tends to mutate and can cause cancer. The researchers found that later-stage...

A Purdue University researcher has discovered that the absence of certain proteins needed for proper cell duplication can lead to cancer. Xiaoqi Liu, an assistant professor of biochemistry, found that cytoplasmic linker protein-170, or CLIP-170, plays a major role in proper cell duplication and DNA distribution. When the protein is removed, cell duplicates lack entire copies of DNA and can become cancerous. Liu's findings were published in the early online version of the Journal of Biological...

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."This provides the mechanism for how p53 loses...


Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
