Abstract: The present invention concerns methods useful in diagnosing, identifying and monitoring the progression of eosinophilic esophagitis through measurements of gene products induced by IL-13.

Abstract: Methods and compositions disclosed herein generally relates to methods of determining minimum hematopoietic stem cell (HSC) chimerism and gene dosage for correction of a hematopoietic disease; in particular, in in vivo models. The invention also relates to modified lentiviral expression vectors for increase a viral titer and various methods for increasing such titers as well as expression vectors capable of enhancing such titers. The invention also relates to CHS4 chromatin insulator-derived functional insulator sequences. The invention further relates to methods for genetic correction of diseases or reducing symptoms thereof, such as sickle cell anemia, a lysosomal storage disease. The invention further relates to a method of improving and/or correcting one or more central nervous system (CNS) abnormalities caused by one or more lysosomal storage disease.

Abstract: Gene expression in peripheral blood from individuals with Duchenne muscular dystrophy (DMD), compared to control individuals, demonstrated differential gene sets that could be used in a method to diagnose DMD, to evaluate effect of DMD therapy, and/or to evaluate propensity to DMD.

Abstract: The preferred embodiments generally relate to methods and compositions that affect the GTP-binding activity of members of the Rho family GTPases, preferably Rac (Rac1, Rac2 and/or Rac3), such compositions include compounds that modulate the GTP/GDP exchange activity, along with uses for the compounds including screening for compounds which recognize Rac GTPase, and methods of treating pathological conditions associated or related to a Rho family GTPase, including Rac. The preferred embodiments also relate to methods of using such compounds, or derivatives thereof, e.g., in therapeutics, diagnostics, and as research tools.

Abstract: A method to evaluate eosinophilic esophagitis based on information in an eosinophilic esophagitis transcriptome.
