A reciprocal repression between ZEB1 and members of the miR-200 family promotes EMT and invasion in cancer cells

EMBO Reports, 2008
The embryonic programme ‘epithelial–mesenchymal transition’ (EMT) is thought to promote malignant tumour progression. The transcriptional repressor zinc‐finger E‐box binding homeobox 1 (ZEB1) is a crucial inducer of EMT in various human tumours, and was ...

Quantum Gravity and Turning Points in the Semiclassical Approximation [PDF]

, 1996
The wavefunctional in quantum gravity gives an amplitude for 3-geometries and matter fields. The four-space is usually recovered in a semiclassical approximation where the gravity variables are taken to oscillate rapidly compared to matter variables ...

Landscape of transcription in human cells

Nature, 2012
Eukaryotic cells make many types of primary and processed RNAs that are found either in specific subcellular compartments or throughout the cells. A complete catalogue of these RNAs is not yet available and their characteristic subcellular localizations ...

Self-bound models of compact stars and recent mass-radius measurements

, 2011
The exact composition of a specific class of compact stars, historically referred to as "neutron stars", is still quite unknown. Possibilities ranging from hadronic to quark degrees of freedom, including self-bound versions of the latter have been ...

A Quality Improvement Initiative to Standardize Pneumocystis jirovecii Pneumonia Prophylaxis in Pediatric Patients With Solid Tumors

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Pediatric patients with extracranial solid tumors (ST) receiving chemotherapy are at an increased risk for Pneumocystis jirovecii pneumonia (PJP). However, evidence guiding prophylaxis practices in this population is limited. A PJP‐related fatality at our institution highlighted inconsistent prescribing approaches and concerns about
