Two signaling pathways essential to normal human development - the Wnt/Wingless (Wnt) and epidermal growth factor receptor (EGFR) pathways - interact in ways that can promote tumor cell invasion and metastasis, researchers from The University of Texas M. D. Anderson Cancer Center report in the Nov. 25 issue of Molecular Cell. http://www.physorg.com/news178377136.html Medicine & Health Wed, 25 Nov 2009 13:30:02 EST news178377136 Scientists have developed a new approach for surveying phosphorylation, a process that is regulated by critical cell signaling pathways and regulates several key cellular signaling events. The research, published by Cell Press in the April 10th issue of the journal Molecular Cell, describes the regulation of a previously uncharacterized protein and demonstrates that it plays an important role in cancer cell invasion. http://www.physorg.com/news158502443.html Medicine & Health Thu, 09 Apr 2009 13:27:55 EST news158502443 The human papillomavirus (HPV) allows infected cervical and head and neck cancer cells to maintain internal molecular conditions that make the cancers resistant to therapy and more likely to grow and spread, resulting in a poor prognosis for patients, researchers with UCLA's Jonsson Cancer Center found. http://www.physorg.com/news144947268.html Medicine & Health Mon, 03 Nov 2008 15:07:48 EST news144947268 (PhysOrg.com) -- After spending years developing a computational model to help illuminate cell signaling pathways, a team of MIT researchers decided to see what would happen if they "broke" the model. http://www.physorg.com/news143380362.html Biology Thu, 16 Oct 2008 12:52:42 EST news143380362 New research suggests that the identification and examination of key cell signaling events required for initiation and progression of cancer might be best accomplished at the single cell level. The research, published by Cell Press in the October issue of the journal Cancer Cell, provides new insight that may lead to better diagnosis and treatment of some complex cancers. http://www.physorg.com/news142518188.html Medicine & Health Mon, 06 Oct 2008 13:23:08 EST news142518188
