LCN2 is involved in various cellular functions, including transport of small hydrophobic molecules, protection of MMP9 from proteolytic degradation, and regulating innate immunity. LCN2 is elevated in multiple human cancers, frequently being associated with tumor size, stage, and invasiveness. Our previous studies have shown that LCN2 expression could be induced by 12-O-tetradecanoylphorbol-13-...
The nucleic acid-binding proteins of bovine leukemia virus (BLV) and feline leukemia virus (FeLV) were isolated in a high state of purity with chloroform-methanol extraction followed by reversed-phase liquid chromatography. Selective solubilization and purity of BLV p12 and FeLV p10 was confirmed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The compositions and molecular weight...
Quantitative determinations of the phosphorus distribution in the eggs of a variety of species by Tschernorutzki (l), Massing (2), and Needham and Needham (3) have indicated the probable presence of nucleoproteins in unfertilized ova. Unfortunately, however, the presence of vitellins in such cells renders the exact interpretation of such analyses somewhat difficult since, with current methods o...
BACKGROUND The packaging, expression, and maintenance of nuclear genomes using histone proteins is a ubiquitous and fundamental feature of eukaryotic cells, yet the phylum Dinoflagellata has apparently abandoned this model of nuclear organization. Their nuclei contain permanently condensed, liquid crystalline chromosomes that seemingly lack histone proteins, and contain remarkably large genomes...
The reversible interaction of a 9-aminoacridine derivative with the ribonucleic acid of yeast was reported in a preliminary paper (1). The present report is concerned with a study of the binding of 2-methoxy-6-chloro-9(l’-methyl-8’-diethylaminooctylamino)acridine (SN-12868)’ by the nucleoprotein and desoxypentose nucleic acid of beef spleen, and additional data are presented for the interaction...
Most experimental studies of epistasis in evolution have focused on adaptive changes-but adaptation accounts for only a portion of total evolutionary change. Are the patterns of epistasis during adaptation representative of evolution more broadly? We address this question by examining a pair of protein homologs, of which only one is subject to a well-defined pressure for adaptive change. Specif...
Factor B (Bf), an enzyme of the alternative pathway of complement activation, is one of four major histocompatibility complex (MHC) class III genes. To ascertain the genetic mechanism for tissue-specific constitutive and regulated expression of Bf, we sequenced the regulatory regions 5' of the gene from mice of different H-2 MHC haplotypes and assessed trans-acting factors, specific DNA binding...
