Mutation tracking in circulating tumor DNA predicts relapse in early breast cancer.
(AMER ASSOC ADVANCEMENT SCIENCE, 2015-08-26)
The identification of early-stage breast cancer patients at high risk of relapse would allow tailoring of adjuvant therapy approaches. We assessed whether analysis of circulating tumor DNA (ctDNA) in plasma can be used to ...
Combined Pan-RAF and MEK Inhibition Overcomes Multiple Resistance Mechanisms to Selective RAF Inhibitors.
(AMER ASSOC CANCER RESEARCH, 2015-12-01)
RAF and MEK inhibitors are effective in BRAF-mutant melanoma but not in BRAF-mutant colorectal cancer. To gain additional insights into this difference, we performed a genome-scale pooled shRNA enhancer screen in a ...
Efficient Genotyping of KRAS Mutant Non-Small Cell Lung Cancer Using a Multiplexed Droplet Digital PCR Approach.
(PUBLIC LIBRARY SCIENCE, 2015-09-28)
Droplet digital PCR (ddPCR) can be used to detect low frequency mutations in oncogene-driven lung cancer. The range of KRAS point mutations observed in NSCLC necessitates a multiplex approach to efficient mutation detection ...
Large-Scale Profiling of Kinase Dependencies in Cancer Cell Lines.
(CELL PRESS, 2016-03-15)
One approach to identifying cancer-specific vulnerabilities and therapeutic targets is to profile genetic dependencies in cancer cell lines. Here, we describe data from a series of siRNA screens that identify the kinase ...
Whole-exome sequencing reveals the mutational spectrum of testicular germ cell tumours.
(NATURE PUBLISHING GROUP, 2015-01-22)
Testicular germ cell tumours (TGCTs) are the most common cancer in young men. Here we perform whole-exome sequencing (WES) of 42 TGCTs to comprehensively study the cancer's mutational profile. The mutation rate is uniformly ...
Targeting molecular addictions in cancer.
(NATURE PUBLISHING GROUP, 2014-11-25)
Cancer cells depend on a finite number of critical signals for their survival. Oncogene addiction, that is, the acquired dependence of a cancer cell on the activity of a single oncogenic gene product, has been the basis ...
Identification of four novel susceptibility loci for oestrogen receptor negative breast cancer.
(NATURE PORTFOLIO, 2016-04-27)
Common variants in 94 loci have been associated with breast cancer including 15 loci with genome-wide significant associations (P<5 × 10(-8)) with oestrogen receptor (ER)-negative breast cancer and BRCA1-associated breast ...
Over-expression of the miR-483-3p overcomes the miR-145/TP53 pro-apoptotic loop in hepatocellular carcinoma.
(IMPACT JOURNALS LLC, 2016-05-24)
The miR-145-5p, which induces TP53-dependent apoptosis, is down-regulated in several tumors, including hepatocellular carcinomas (HCCs), but some HCCs show physiological expression of this miR. Here we demonstrate that in ...
DNA-Repair Defects and Olaparib in Metastatic Prostate Cancer.
(MASSACHUSETTS MEDICAL SOC, 2015-10-29)
BACKGROUND: Prostate cancer is a heterogeneous disease, but current treatments are not based on molecular stratification. We hypothesized that metastatic, castration-resistant prostate cancers with DNA-repair defects would ...
Oncogenic KRAS sensitizes premalignant, but not malignant cells, to Noxa-dependent apoptosis through the activation of the MEK/ERK pathway.
(IMPACT JOURNALS LLC, 2015-05-10)
KRAS is mutated in about 20-25% of all human cancers and especially in pancreatic, lung and colorectal tumors. Oncogenic KRAS stimulates several pro-survival pathways, but it also triggers the trans-activation of pro-apoptotic ...
