TranscriptomicsSingle Cell RNA-sequencing of Pancreatic Circulating Tumor Cells
Circulating Tumor Cells (CTCs) are shed from primary tumors into the bloodstream, mediating the hematogenous spread of cancer to distant organs. Using a pancreatic cancer mouse model, we applied a microfluidic device to isolate CTCs independently of tumor epitopes, subjecting these to single cell RN...

TranscriptomicsRNA sequencing of circulating tumour cells implicates WNT signaling in pancreatic cancer metastasis (human data)
Circulating tumour cells (CTCs) shed into blood from primary cancers include putative precursors that initiate distal metastases. While these cells are extraordinarily rare, they may identify cellular pathways contributing to the blood-borne dissemination of cancer. Here, we adapted a microfluidic d...

TranscriptomicsIsolation and Molecular Characterization of Circulating Melanoma Cells
Melanoma is an invasive malignancy with a high frequency of blood-borne metastases, but circulating tumor cells (CTCs) have not been readily isolated. We adapted microfluidic CTC capture to a tamoxifen-driven B-RAF/PTEN mouse melanoma model. CTCs were detected in all tumor-bearing mice, rapidly decl...

TranscriptomicsWTX interacts with the transcriptional regulator TRIM28 to mediate cellular differentiation
WTX encodes a tumor suppressor implicated in Wilms tumor and in mesenchymal differentiation, with distinct functions in the cytoplasm, at the plasma membrane and in the nucleus. Here we report that the transcriptional corepressor TRIM28 is the major binding partner for nuclear WTX. The WTX-TRIM28 in...

TranscriptomicsCirculating Tumor Cell Clusters are Oligoclonal Precursors of Breast Cancer Metastasis
Clusters of circulating tumor cells (CTC-clusters) are present in the blood of patients with cancer but their contribution to metastasis is not well defined. Here, we first use mouse models to demonstrate that breast cancer cells injected intravascularly as clusters are more prone to survive and col...

TranscriptomicsRNA-Seq of Single Prostate CTCs Implicates Non-Canonical Wnt Signaling in Antiandrogen Resistance
Prostate cancer is initially responsive to androgen deprivation, but the effectiveness of androgen receptor (AR) inhibitors in recurrent disease is variable. Biopsy of bone metastases is challenging, hence sampling circulating tumor cells (CTCs) may reveal drug resistance mechanisms. We established ...

TranscriptomicsHuman Pancreatic CTCs Express the ECM Protein SPARC
Circulating Tumor Cells (CTCs) are shed from primary tumors into the bloodstream, mediating the hematogenous spread of cancer to distant organs. To determine the relevance of ECM protein expression to human disease, CTCs were isolated from the blood of metastatic PDAC patients and subjected to singl...

TranscriptomicsPericentromeric satellite repeat expansions through RNA-derived DNA intermediates in cancer
Aberrant transcription of the HSATII pericentromeric satellite repeat is present in a wide variety of epithelial cancers. We observed that HSATII expression is induced in colon cancer cells cultured as xenografts or under non-adherent conditions in vitro, but it is rapidly lost in standard 2D cultur...
