The CBX7 gene encodes a polycomb group protein that is known to be downregulated in many types of human cancers, although the role this carcinogenesis remains unclear. To shed light on issue, we generated mice null for Cbx7. Mouse embryonic fibroblasts derived from these had higher growth rate and reduced susceptibility senescence compared with their WT counterparts. This was associated upregulated expression multiple cell cycle components, including cyclin E, which play key lung humans....

When tumour tissue is unavailable, cell-free DNA (cfDNA)can serve as a surrogate for genetic analyses. Because mutated alleles in cfDNA are usually below 1%, next-generation sequencing (NGS)must be narrowed to target only clinically relevant genes. In this proof-of-concept study, we developed panel use ultra-deep identify such mutations cfDNA.Our ('SiRe') covers 568 six genes (EGFR, KRAS, NRAS, BRAF, cKIT and PDGFRα)involved non-small-cell lung cancer (NSCLC), gastrointestinal stromal...

Resistance to tyrosine kinase inhibitors (TKI) of EGF receptor (EGFR) is often related activation other signaling pathways and evolution through a mesenchymal phenotype.Because the Hedgehog (Hh) pathway has emerged as an important mediator epithelial-to-mesenchymal transition (EMT), we studied Hh in models EGFR-TKIs intrinsic or acquired resistance from both EGFR-mutated wild-type (WT) non-small cell lung cancer (NSCLC) lines.Activation was found EGFR-WT NSCLC line resistant EGFR-TKIs. In...

Abstract Purpose: BRAF mutations are grouped in activating RAS-independent signaling as monomers (class 1–V600E) or dimers 2–codons 597/601), and RAS-dependent with impaired kinase activity 3–codons 594/596). Although clinical, pathologic, molecular features of V600EBRAF-mutated metastatic colorectal cancer (mCRC) well known, limited data available from the two other classes. Experimental Design: Data 117 patients (92 class 1, 12 2, 13 3)-mutated mCRC were collected. A total 540 wt mCRCs...

Many advanced cases of cancer show central nervous system, pleural, or peritoneal involvement. In this study, we prospectively analyzed if cerebrospinal fluid (CSF), pleural effusion (PE), and/or ascites (ASC) can be used to detect driver mutations and guide treatment decisions. We collected 42 CSF, PE, ASC samples from non‐small‐cell lung melanoma patients. Cell‐free DNA (cfDNA) was purified quantified by PNA‐Q‐PCR next‐generation sequencing. All were evaluable; clinically relevant detected...
