Abstract: Disclosed are a data processing and analysis method of gene expression data for identifying endogenous reference genes and a composition for the quantitative analysis of gene expression, comprising a pair of primers and/or probes useful in the amplification of the identified endogenous reference genes. Introduced with the concepts of “Zero's proportion’ and CV, the me allows different datasets to be integrally analyzed, thereby searching for novel reference genes. By the method, 2,087 genes are first found as housekeeping genes which are expressed in most tissues, and the usefulness thereof in the relative quantification of different target genes is determined by analyzing their expression stability. Out of the 2,087 genes, 13 genes are found to show higher expression stability with lower expression levels across a wide range of samples than traditional reference genes such as GAPDH and ACTB, and therefore are suitable for the normalization of universal genes having relatively low expression levels.

Abstract: Provided are an apparatus and method for reducing a PAPR with less computation complexity without distortion using a selected mapping scheme (SLM) in an OFDM system. The method includes: generating a plurality of OFDM signal sequences by performing an inverse fast Fourier transform (IFFT) operation on input symbol sequences, which are probabilistically independent and have identical information; linearly combining the plurality of OFDM signal sequences by using complex numbers; and generating different OFDM signal sequences based on the linear combination. Accordingly, the number of phase sequences can be increased without almost increasing a computation amount of SLM.

Abstract: Disclosed are novel ?-galactosylceramide derivatives, pharmaceutically acceptable salts thereof, preparation methods thereof, and pharmaceutical compositions for use in an immune adjuvant containing the same as an active ingredient. The derivatives, in which the amide moiety of ?-GalCer is bioisosterically replaced with a triazole moiety, direct cytokine secretion toward IL-4 rather than IFN-? and thus can be used as a therapeutic for autoimmune diseases regulated by IL-4, such as type 1 diabetes and multiple sclerosis.

Abstract: The present invention relates to an angiogenesis inhibitor comprising meteorin as an active ingredient that is highly expressed in astrocytes of the brain and retina in the late embryonic stage and after the birth of a mouse. It is in particular highly detected in astrocyte endfeet surrounding blood vessels and promotes the expression of thrombospondin-1/-2 (TSP-1/-2) via autocrine pathway and thus inhibits angiogenesis. The meteorin of the present invention can be effectively used for pharmaceutical compositions and health foods that prevent vascular diseases by inhibiting angiogenesis.
