Cancer Cells Retrace a Stepwise Differentiation Program during Malignant Progression

Douglas Hanahan, Krisztian Homicsko, Stephan Wullschleger, Mohammad Sadegh Saghafinia, Iacovos Michael, Giovanni Ciriello

Pancreatic neuroendocrine tumors (PanNET) comprise two molecular subtypes, relatively benign islet tumors (IT) and invasive, metastasis-like primary (MLP) tumors. Until now, the origin of aggressive MLP tumors has been obscure. Herein, using multi-omics ap ...

A miR-375/YAP axis regulates neuroendocrine differentiation and tumorigenesis in lung carcinoid cells

Mohammad Sadegh Saghafinia, Iacovos Michael

Lung carcinoids are variably aggressive and mechanistically understudied neuroendocrine neoplasms (NENs). Here, we identified and elucidated the function of a miR-375/yes-associated protein (YAP) axis in lung carcinoid (H727) cells. miR-375 and YAP are res ...

Synaptic proximity enables NMDAR signalling to promote brain metastasis

Graham Knott, Douglas Hanahan, Mohammad Sadegh Saghafinia, Iacovos Michael, Qiqun Zeng, Brian Donal McCabe, Wei Jiao, Giovanni Ciriello, Peng Zhang, Inti Zlobec

Metastasis-the disseminated growth of tumours in distant organs-underlies cancer mortality. Breast-to-brain metastasis (B2BM) is a common and disruptive form of cancer and is prevalent in the aggressive basal-like subtype, but is also found at varying freq ...

ALK7 Signaling Manifests a Homeostatic Tissue Barrier That Is Abrogated during Tumorigenesis and Metastasis

Nadine Fournier, Douglas Hanahan, Mohammad Sadegh Saghafinia, Iacovos Michael, Mélanie Louise Tichet

Herein, we report that the TGF beta superfamily receptor ALK7 is a suppressor of tumorigenesis and metastasis, as revealed by functional studies in mouse models of pancreatic neuroendocrine and lumina! breast cancer, complemented by experimental metastasis ...

A set of microRNAs coordinately controls tumorigenesis, invasion, and metastasis

Douglas Hanahan, Mohammad Sadegh Saghafinia, Iacovos Michael

MicroRNA-mediated gene regulation has been implicated in various diseases, including cancer. This study examined the role of microRNAs (miRNAs) during tumorigenesis and malignant progression of pancreatic neuroendocrine tumors (PanNETs) in a genetically en ...

Angiopoietin-1 deficiency increases tumor metastasis in mice

Iacovos Michael

Background: Angipoietin-1 activation of the tyrosine kinase receptor Tek expressed mainly on endothelial cells leads to survival and stabilization of endothelial cells. Studies have shown that Angiopoietin-1 counteracts permeability induced by a number of ...

Functional malignant cell heterogeneity in pancreatic neuroendocrine tumors revealed by targeting of PDGF-DD

Iacovos Michael

Intratumoral heterogeneity is an inherent feature of most human cancers and has profound implications for cancer therapy. As a result, there is an emergent need to explore previously unmapped mechanisms regulating distinct subpopulations of tumor cells and ...
