KRAS mutation is associated with elevated myeloblastin activity in human lung adenocarcinoma


Wiedl, T; Collaud, S; Hillinger, S; Arni, S; Burgess, C; Kroll, W; Schraml, P; Soltermann, A; Moch, H; Weder, W (2012). KRAS mutation is associated with elevated myeloblastin activity in human lung adenocarcinoma. Cancer Genomics & Proteomics, 9(1):51-54.

Abstract

Lung cancer is the leading cause of all cancer deaths worldwide with suboptimal prognosis and treatment options. Therefore this study aimed to identify molecular characteristics with a predictive clinical utility which at the same time might represent novel therapeutic targets for human lung adenocarcinoma. Within this study mutations of v-Ki-RAS2 Kirsten rat sarcoma viral oncogene homolog (KRAS), a gene frequently mutated in lung adenocarcinoma, and their association with enzymatic activities, as assessed by activity-based proteomics, of members of the serine hydrolase (SH) superfamily, a large class of enzymes that have previously been linked to cancer was investigated. The results revealed that the activity of myeloblastin was significantly altered in the lung adenocarcinoma biopsies harboring a KRAS gene mutation. In conclusion myeloblastin is a potential therapeutic target for human lung adenocarcinoma, indicating that the combination of activity-based proteomics with mutational analysis is a valid approach for the discovery of novel biomarkers.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
