Stromal communication with cancer cells can influence treatment response. We show that stromal and breast cancer (BrCa) cells utilize paracrine and juxtacrine signaling to drive chemotherapy and radiation resistance. Upon heterotypic interaction, exosomes are transferred from stromal to BrCa cells. RNA within exosomes, which are largely noncoding(More)
Tumour metastasis suppressors are inhibitors of metastasis but their mechanisms of action are generally not understood. We previously showed that the suppressor Raf kinase inhibitory protein (RKIP) inhibits breast tumour metastasis in part via let-7. Here, we demonstrate an integrated approach combining statistical analysis of breast tumour gene expression(More)
BACKGROUND Changes in epithelial cell interactions have been implicated in carcinogenesis, tumour invasion and metastasis. AIM To screen for altered expression of epithelial adhesion genes in lung cancer development. METHODS Gene expression profiles were assessed with cDNA expression arrays in eight non-small cell lung cancer (NSCLC) and eight normal(More)
Cigarette smoking is the main risk factor for the development of squamous cell lung carcinoma (SCC). However, the smoking-related molecular changes in SCC have not been studied. Gene expression studies in both histologically normal bronchial epithelium and SCC epithelial samples identified genes differentially expressed between current and ex-smokers.(More)
About 50% of patients presenting with resectable lung cancer develop distant metastases within 5 years. Genomic markers predicting metastatic behaviour of squamous cell lung carcinoma (SCC) are currently underexposed. We analyzed a cohort of patients with primary SCC using array-based comparative genomic hybridization (aCGH) to identify which genomic(More)
Large-scale sequencing studies are rapidly identifying putative oncogenic mutations in human tumors. However, discrimination between passenger and driver events in tumorigenesis remains challenging and requires in vivo validation studies in reliable animal models of human cancer. In this study, we describe a novel strategy for in vivo validation of(More)
The epidemiological relationship between squamous cell lung cancer (SCC) and chronic obstructive pulmonary disease (COPD), both smoking-related diseases, suggests that they have also a genetic basis. We compared 35 SCC patients with and without COPD with whole-genome gene expression profiles of laser microdissected tissue. Validation of differential(More)
Laser microdissection microscopy has become a rising tool to assess gene expression profiles of pure cell populations. Given the low yield of RNA, a second round of amplification is usually mandatory to yield sufficient amplified-RNA for microarray approaches. Since amplification induces truncation of RNA molecules, we studied the impact of a second round(More)
Thank you for submitting your manuscript for consideration by the EMBO Journal. It has now been seen by two referees whose comments are enclosed. As you will see, both referees express interest in your work and are broadly in favour of publication, pending satisfactory revision. Both referees request a number of additional experiments, as well as various(More)
To improve current angiogenic gene therapy with a vascular endothelial growth factor (VEGF)-encoding plasmid (Baumgartner et al. Circulation 1998; 97: 1114–23 [1]; Kusumanto et al. Fifth Annual Meeting of the American Society of Gene Therapy, Boston, 2002, Abstr. 621 [2]), we have generated a combination plasmid, encoding the VEGF gene and the thymidine(More)
