Genomic analysis identifies association of Fusobacterium with colorectal carcinoma

…, J Tabernero, J Baselga, C Liu, RA Shivdasani… - Genome …, 2012 - genome.cshlp.org
The tumor microenvironment of colorectal carcinoma is a complex community of genomically
altered cancer cells, nonneoplastic cells, and a diverse collection of microorganisms. Each …

Absence of blood formation in mice lacking the T-cell leukaemia oncoprotein tal-1/SCL

RA Shivdasani, EL Mayer, SH Orkin - Nature, 1995 - nature.com
CHROMOSOMAL translocations associated with malignancies often result in deregulated
expression of genes encoding transcription factors 1 . In human T-cell leukaemias such …

SOX2 is an amplified lineage-survival oncogene in lung and esophageal squamous cell carcinomas

…, UR Jr, SK Marie, O Dahl, RA Shivdasani… - Nature …, 2009 - nature.com
Lineage-survival oncogenes are activated by somatic DNA alterations in cancers arising
from the cell lineages in which these genes play a role in normal development 1 , 2 . Here we …

[HTML][HTML] A lineage‐selective knockout establishes the critical role of transcription factor GATA‐1 in megakaryocyte growth and platelet development

RA Shivdasani, Y Fujiwara, MA McDevitt… - The EMBO journal, 1997 - embopress.org
Transcription factor GATA‐1 is essential for red blood cell maturation and, therefore, for survival
of developing mouse embryos. GATA‐1 is also expressed in megakaryocytes, mast cells…

Transcription factor NF-E2 is required for platelet formation independent of the actions of thrombopoeitin/MGDF in megakaryocyte development

RA Shivdasani, MF Rosenblatt, D Zucker-Franklin… - Cell, 1995 - cell.com
Despite the importance of blood platelets in health and disease, the mechanisms regulating
their formation within megakaryocytes are unknown. We generated mice lacking the …

[PDF][PDF] Small-molecule antagonists of the oncogenic Tcf/β-catenin protein complex

…, F Petersen, C Bruseo, AW Wood, RA Shivdasani - Cancer cell, 2004 - cell.com
Key molecular lesions in colorectal and other cancers cause β-catenin-dependent
transactivation of T cell factor (Tcf)-dependent genes. Disruption of this signal represents an …

Dynamic visualization of thrombopoiesis within bone marrow

…, DD Wagner, T Graf, JE Italiano Jr, RA Shivdasani… - Science, 2007 - science.org
Platelets are generated from megakaryocytes (MKs) in mammalian bone marrow (BM) by
mechanisms that remain poorly understood. Here we describe the use of multiphoton intravital …

CDK8 is a colorectal cancer oncogene that regulates β-catenin activity

…, DE Root, CS Fuchs, M Loda, RA Shivdasani… - Nature, 2008 - nature.com
Aberrant activation of the canonical WNT/β-catenin pathway occurs in almost all colorectal
cancers and contributes to their growth, invasion and survival 1 , 2 . Although dysregulated β-…

Blood platelets are assembled principally at the ends of proplatelet processes produced by differentiated megakaryocytes

JE Italiano Jr, P Lecine, RA Shivdasani… - The Journal of cell …, 1999 - rupress.org
Megakaryocytes release mature platelets in a complex process. Platelets are known to be
released from intermediate structures, designated proplatelets, which are long, tubelike …

Activation of ERBB2 signaling causes resistance to the EGFR-directed therapeutic antibody cetuximab

…, K Okuno, JA Engelman, RA Shivdasani… - Science translational …, 2011 - science.org
Cetuximab, an antibody directed against the epidermal growth factor receptor, is an effective
clinical therapy for patients with colorectal, head and neck, and non–small cell lung cancer, …
