TranscriptomicsHigh-resolution aCGH analyses of copy number alterations in HER2-amplified breast cancer
HER2 gene amplification and protein overexpression (HER2+) define a clinically challenging subgroup of breast cancer with variable prognosis and response to therapy. Although gene expression profiling has identified an ERBB2 molecular subtype of breast cancer, it is clear that HER2+ tumors reside in...

TranscriptomicsIdentification of new microRNAs in paired normal and tumor breast tissue suggests a dual role for the ERBB2/Her2 gene
To comprehensively characterize microRNA (miRNA) expression in breast cancer, we performed the first extensive next-generation sequencing expression analysis of this disease. We sequenced small RNA from tumors with paired samples of normal and tumor-adjacent breast tissue. Our results indicate that ...

TranscriptomicsIdentification of subtypes in HER2-positive breast cancer reveals a gene signature prognostic of outcome
Purpose HER2 gene amplification or protein overexpression (HER2+) defines a clinically challenging subgroup of breast cancer with variable prognosis and response to therapy. We aimed to investigate the heterogeneous biological appearance and clinical behavior of HER2+ tumors using molecular profilin...

TranscriptomicsThe retinoblastoma gene is targeted for rearrangements in BRCA1-deficient basal-like breast cancer.
Breast tumors from BRCA1 germ line mutation carriers typically exhibit features of the basal-like molecular subtype. However, the specific genes recurrently mutated as a consequence of BRCA1 dysfunction have not been fully elucidated. In this study, we utilized gene expression profiling to molecular...

TranscriptomicsCo-targeting of the PI3K pathway improves the response of BRCA1 deficient breast cancer cells to PARP1 inhibition
Although pre-clinical and clinical studies on PARP1 inhibitors, alone and in combination with DNA-damaging agents, show promising results, further ways to improve and broaden the scope of application of this therapeutic approach are warranted. To this end, we have investigated the possibility of imp...

TranscriptomicsGenomic Subtypes of Breast Cancer Identified by Array Comparative Genomic Hybridization
Breast cancer is a profoundly heterogeneous disease with respect to biological and clinical behavior. Gene expression profiling has been used to dissect this complexity and stratify tumors into intrinsic gene expression subtypes associated with distinct biology, patient outcome and different genomic...
