In our studies, we determined that clinical biological correlates are likely to be more accurate when different aspects of EGFR are evaluated in combination. We analyzed EGFR phosphorylation, expression and mutations in 60 primary head and neck tumors. We not only found that head and neck tumors with either truncated or activated EGFR tend to have higher tumor and nodal stage, but also discovered three EGFR truncations.Type: ApplicationFiled: May 5, 2011Publication date: August 15, 2013Inventors: Edward L.

Publication number: 20130210019Abstract: The present invention relates to a method for amplifying a template nucleic acid, wherein the method comprises amplifying said template nucleic acid using the helicase dependent amplification (HDA) reaction in the presence of a nicking endonuclease, and wherein said template nucleic acid comprises a sequence recognized by said nicking endonuclease or a sequence recognized by said nicking endonuclease is introduced into the template nucleic acid during the HDA reaction. The invention further pertains to a kit for amplifying a nucleic acid, comprising a nicking endonuclease, a helicase and a DNA polymerase.Type: ApplicationFiled: August 16, 2011Publication date: August 15, 2013Applicant: QIAGEN GMBHInventors: Christian Korfhage, Gerd Grosshauser, Thomas Rothmann, Ralf Himmelreich
