Intraductal patient-derived xenografts of estrogen receptor α-positive breast cancer recapitulate the histopathological spectrum and metastatic potential of human lesions

Cathrin Brisken, Georgios Sflomos, Ayyakkannu Ayyanan, Laura Battista, Maryse Fiche, Valentina Scabia, Patrik Aouad, Valérian Charles Robert Dormoy

Estrogen receptor α-positive (ER-positive) or 'luminal' breast cancers were notoriously difficult to establish as patient-derived xenografts (PDXs). We and others recently demonstrated that the microenvironment is critical for ER-positive tumor cells; when ...

Time-Dependent Diffusion MRI in Cancer: Tissue Modeling and Applications

Olivier Benoit Thomas Reynaud

In diffusion weighted imaging (DWI), the apparent diffusion coefficient (ADC) has been recognized as a useful and sensitive surrogate for cell density, paving the way for non-invasive tumor staging, and characterization of treatment efficacy in cancer. How ...

Label-free nanoplasmonic sensing of tumor-associate autoantibodies for early diagnosis of colorectal cancer

Maria Soler Aznar

Colorectal cancer is treatable and curable when detected at early stages. However there is a lack of less invasive and more specific screening and diagnosis methods which would facilitate its prompt identification. Blood circulating autoantibodies which ar ...

Acidic tumor microenvironment abrogates the efficacy of mTORC1 inhibitors

Anne Planche, Tania Santoro

Background: Blocking the mechanistic target of rapamycin complex-1 (mTORC1) with chemical inhibitors such as rapamycin has shown limited clinical efficacy in cancer. The tumor microenvironment is characterized by an acidic pH which interferes with cancer t ...

A Cross-Species Analysis in Pancreatic Neuroendocrine Tumors Reveals Molecular Subtypes with Distinctive Clinical, Metastatic, Developmental, and Metabolic Characteristics

Douglas Hanahan, Anguraj Sadanandam, Stephan Wullschleger, Ismaël Wafy

Seeking to assess the representative and instructive value of an engineered mouse model of pancreatic neuroendocrine tumors (PanNET) for its cognate human cancer, we profiled and compared mRNA and miRNA transcriptomes of tumors from both. Mouse PanNET tumo ...

Gene expression mapping of histone deacetylases and co-factors, and correlation with survival time and 1H-HRMAS metabolomic profile in human gliomas

Johan Auwerx

Primary brain tumors are presently classified based on imaging and histopathological techniques, which remains unsatisfaying. We profiled here by quantitative real time PCR (qRT-PCR) the transcripts of eighteen histone deacetylases (HDACs) and a subset of ...

The biology of personalized cancer medicine: facing individual complexities underlying hallmark capabilities

Michele De Palma, Douglas Hanahan

It is a time of great promise and expectation for the applications of knowledge about mechanisms of cancer toward more effective and enduring therapies for human disease. Conceptualizations such as the hallmarks of cancer are providing an organizing princi ...

Protein-binding microarray technology and ChIP-sequencing for the identification of novel targets of the human tumor suppressor AP2[alpha]

Jan Kerschgens

The mis-regulation of gene transcription in the living cell can be the cause of complex human diseases like cancer. One challenge of the post-genomic era of biomedical research is the development of in vitro techniques for the rapid and cost-effective anal ...

Cutaneous melanoma in genetically modified animals

Friedrich Beermann

Cutaneous melanomas are tumors originating from skin melanocytes which are present in hair follicles, and interfollicular epidermal and dermal layers. Experimental work in model systems involves in silico, in vitro and in vivo analyses. Such models allow t ...

Lymphatic function, lymphangiogenesis, and cancer metastasis

Melody Swartz

The lymphatic system serves as the primary route for the metastasis of many cancers and the extent of lymph node involvement is the most important indicator of tumor aggressiveness. Despite the apparent importance of the lymphatic vessels for tumor dissemi ...
