Abstract: Methods of alleviating the symptoms of hemoglobinopathies, including, but not limited to, sickle cell disease, ?-thalassemia, and hemoglobin H disease are provided. In some embodiments, the methods comprise administering an inhibitor selected from an ERK inhibitor, a MEK inhibitor, and a Raf inhibitor. Methods of inhibiting adhesion of sickle red blood cells to endothelial cells are also provided.

Abstract: We provide IDH1 gene-defective cell lines (e.g., IDH1R132H heterozygous and IDH1R132H homozygous) derived from dissociated human astrocytoma samples. The cells can be used alone or in combination with each other or other cell types as a tool for determining the impact of IDH1R132H on cellular biology, tumorigenesis, and metabolic profiles. The cell lines may be used to test and identify therapeutic targets and to screen for molecular therapeutic agents.

Abstract: The present invention relates, in general, to human immunodeficiency virus (HIV), and, in particular, to a method of inducing neutralizing antibodies against HIV, to a method of inducing antibodies protective against HIV and to compounds and compositions suitable for use in such methods.

Abstract: Methods of detecting G protein-coupled receptor (GPCR) activity in vitro and in vivo are provided. In one embodiment, the method includes providing at least one cell that expresses a GPCR and a plurality of conjugated proteins. Each of the plurality of conjugated proteins is formed by conjugating an arrestin protein and a detectable molecule. The plurality of conjugated proteins are substantially evenly distributed in the cytoplasm of the at least one cell. A first image of the at least one cell is obtained by detecting an amount of energy emitted from the detectable molecules and storing a value relative to the amount of energy. The at least one cell is treated with an agonist. A second image of the at least one cell is obtained. The first image and the second image are compared to detect the localization of at least some of the plurality of conjugated proteins at endocytic vesicles and/or endosomes.
