Abstract: Methods, software, and systems are provided for determining the probability of an overlap set of entities having an overlap size, where the overlap set is independently selected from two sets of non-identical entities. Applications of the invention to microarrays are provided. Probability distributions are provided for determining the probability that the size of an overlap gene set from two different microarrays occurs by chance. Microarray analysis for determining the size of a statistically significant overlap gene set given two different microarrays is described. Overlap set size probability determinations that account for the total number of genes in two different microarrays and not just the common genes are described.

Abstract: Methods of generating modified embryos and mammals by introduction of donor cells into an early stage embryo are provided, such that the resulting embryo and animal generated therefrom has a significant contribution to all tissues from the donor cells and is capable of transmitting the donor cell DNA.

Abstract: Formulations of an interleukin-1 (IL-1) antagonist are provided including a pre-lyophilized formulation, a reconstituted lyophilized formulation, and a stable liquid formulation. Preferably, the IL-1 antagonist is an IL-1 trap composed of a dimer of two fusion protein having an amino acid sequence selected from the group consisting of SEQ ID NO: 10.

Abstract: A fusion polypeptide comprising (A)x-M-(A?)y, wherein A and A? are each polypeptides capable of binding a target receptor. The fusion polypeptides of the invention form multimeric proteins which activate the target receptor. A and A? may be each be an antibody or fragment derived from an antibody specific for a target receptor, such as the same or different ScFv fragments, and/or a ligand or ligand fragment or derivative capable of binding the target protein, M is a multimerizing component, and X and Y are independently a number between 1-10.

Abstract: Compositions and methods for the inducible expression of genes in eukaryotic cells. Expression of a nucleotide sequence of interest is controlled by a regulatory fusion protein that consists of a transcription blocking domain and a ligand-binding domain. When the cognate ligand for the ligand-binding domain is present, transcription of the nucleotide sequence of interest is blocked. Upon removal of the cognate ligand, the nucleotide sequence of interest is transcribed. The method is useful for large scale production of a desired product in eukaryotic cells.

Abstract: Methods of treating, inhibiting, or ameliorating an autoinflammatory disorder, disease, or condition in a subject in need thereof, comprising administering to a subject in need a therapeutic amount of an interleukin 1 (IL-1) antagonist, wherein the autoinflammatory disorder, disease, or condition is treated, inhibited, or ameliorated. The IL-1 antagonist is a molecule capable of binding and inhibiting IL-1. The therapeutic methods are useful for treating a human adult or child suffering from Neonatal Onset Multisystem Inflammatory Disorder (NOMID/CINCA), Muckle-Wells Syndrome (MWS), Familial Cold Autoinflammatory Syndrome (FCAS), familial mediterranean fever (FMF), tumor necrosis factor receptor-associated periodic fever syndrome (TRAPS), or systemic onset juvenile idiopathic arthritis (Still's Disease).
