Targeted deep sequencing of mucinous ovarian tumors reveals multiple overlapping RAS-pathway activating mutations in borderline and cancerous neoplasms.
Vancouver, Canada. In Bmc Cancer, 19 Jun 2015
RESULTS: We detected mutations in KRAS, TP53, CDKN2A, PIK3CA, PTEN, BRAF, FGFR2, STK11, CTNNB1, SRC, SMAD4, GNA11 and ERBB2.
Ultra-deep targeted sequencing of advanced oral squamous cell carcinoma identifies a mutation-based prognostic gene signature.
Taiwan. In Oncotarget, 25 May 2015
A mutation-based signature affecting ten genes (HRAS, BRAF, FGFR3, SMAD4, KIT, PTEN, NOTCH1, AKT1, CTNNB1, and PTPN11) was devised to predict DFS.
Pathogenesis of cholangiocarcinoma: From genetics to signalling pathways.
Singapore, Singapore. In Best Pract Res Clin Gastroenterol, 30 Apr 2015
A series of highly recurrent mutations in genes such as TP53, KRAS, SMAD4, BRAF, MLL3, ARID1A, PBRM1 and BAP1, which are known to be involved in cell cycle control, cell signalling pathways and chromatin dynamics, have led to investigations of their roles, through molecular to mouse modelling studies, in cholangiocarcinogenesis.
Whole genomes redefine the mutational landscape of pancreatic cancer.
Brisbane, Australia. In Nature, Mar 2015
Chromosomal rearrangements leading to gene disruption were prevalent, affecting genes known to be important in pancreatic cancer (TP53, SMAD4, CDKN2A, ARID1A and ROBO2) and new candidate drivers of pancreatic carcinogenesis (KDM6A and PREX2).
Novel targets in pancreatic cancer research.
Philadelphia, United States. In Semin Oncol, Feb 2015
For example, PDA is driven by key activating, gain-of-function mutations in proto-oncogenes (eg, K-Ras) along with loss of function of tumor suppressor genes (eg, p16, SMAD4).
SMAD4 and its role in pancreatic cancer.
Shanghai, China. In Tumour Biol, Jan 2015
SMAD4, as one of the Smads family of signal transducer from TGF-β, mediates pancreatic cell proliferation and apoptosis and is specifically inactivated in half of advanced pancreatic cancers.
Diagnosis and molecular aspects of solid-pseudopapillary neoplasms of the pancreas.
Paris, France. In Semin Diagn Pathol, Nov 2014
Distinctive molecular alterations such as the presence of CTNNB1 mutations are observed in nearly all cases, while mutations classically observed in ductal adenocarcinoma, such as KRAS, TP53, and SMAD4, are not observed in SPNs, reinforcing its distinct nature compared to all other pancreatic neoplasms.
