Abstract:
The present invention provides a novel class of detergents referred to herein as lipopeptide detergents. Lipopeptide detergents comprise an amphipathic alpha -helical peptide having a hydrophobic or neutral face and a hydrophilic face. To each end of this peptide is covalently linked an aliphatic hydrocarbon tail, these aliphatic tails being linked thereto such that they associate with the hydrophobic or neutral face of the peptide. Lipopeptide detergents can advantageously be used to stabilize membrane proteins in the absence of a phospholipid bilayer in a manner that preserves the native conformation and permits the subsequent crystallization thereof.
Abstract:
Novel ligands that bind to MUC1 are disclosed. The ligands were isolated using an improved phage display technique using MUC1 tandem repeat as a target. Uses of the ligand to detect, monitor or treat cancer as well as to prepare antibodies is also described.

Abstract:
An imager (10) and a reconstruction processor (12) generate an intensity image (14). A region containing a target volume is identified (20) and limited (24). A classifier (30) operates on the voxels in the limited volume with an enhancement filter to generate an enhanced image, such as an image whose voxel values represent a probability that each voxel is in the target volume. A segmentation processor (40) segments the enhanced image to identify the surface of the target volume to generate a segmented image which is displayed on a monitor (52) or used in a radiation therapy planning system (54).
Abstract:
Provided herein are methods, uses and compositions for treating a patient with cancer wherein the cancer is characterized by a PTEN gene mutation, hi particular embodiments, the methods comprise administering to the patient a composition comprising a therapeutically effective amount of a PLK4 antagonist, and identifying a patient that is likely to be responsive to PLK4 antagonist therapy, if PTEN gene mutation is present.
Abstract:

A pharmaceutical composition comprises a compound represented by Structural Formula (I) or a pharmaceutically acceptable salt thereof. A method of treating a subject having cancer comprises administering to the subject a therapeutically effective amount of a compound represented by Structural Formula (I) or a pharmaceutically acceptable salt thereof.
Abstract:
A method of detecting cellular damage within a subject comprises transmitting low frequency ultrasound (20MHz or below) into a selected site within the subject wherein the selected site has been exposed to a stress capable of causing cellular death at the selected site. At least a portion of ultrasound backscattered from the ultrasound transmitted into the selected site is received. The received backscattered ultrasound is compared to a control backscatter measurement. An increase or a decrease in intensity or spectral slope of the received backscattered ultrasound when compared to the control backscatter measurement indicates cellular death or damage at the selected site within the subject.
Abstract:
The present invention provides two chimeric anti-CD44 antibodies comprising specific animo acid sequence, derived from antibodies A3D8 and H90 and their use, in the preparation of a medicament for eradicating pathological stem cells in cancer therapy, and more specifically in acute myeloid leukaemia therapy.
Abstract:
The PTEN/PI3K signaling pathway regulates a vast array of fundamental cellular responses. We show that cardiomyocyte-specific inactivation of tumor suppressor PTEN results in hypertrophy, and unexpectedly, a dramatic decrease in cardiac contractility. Analysis of double mutant mice revealed that the cardiac hypertrophy and the contractility defects can be genetically uncoupled. PI3Kgamma mediates the alteration in cell size while PI3Kgamma acts as a negative regulator of cardiac contractility. Mechanistically, PI3Kgamma inhibits cAMP production and hypercontractility can be reverted by blocking cAMP function. These data show that PTEN has an important in vivo role in cardiomyocyte hypertrophy and GPCR signaling and identify a function for the PTEN-PI3Kgamma pathway in the modulation of heart muscle contractility.
