The classical (two-round) hypothesis of vertebrate genome duplication proposes two successive whole-genome duplication(s) (polyploidizations) predating the origin of fishes, a view now being seriously challenged. As the debate largely concerns the relative merits of the 'big-bang mode' theory (large-scale duplication) and the 'continuous mode' theory(More)
We used the yeast genome sequences of gene families, microarray profiles and regulatory motif data to test the current wisdom that there is a strong correlation between regulatory motif structure and gene expression profile. Our results suggest that duplicate genes tend to be co-expressed but the correlation between motif content and expression similarity(More)
Despite only approximately 1% difference in genomic DNA sequence, humans and chimpanzees differ considerably in mental and linguistic capabilities, and in susceptibility to some diseases. A recent comparison of gene expression in human and great apes cast some light on the genetic basis of these differences, but more rigorous study is required. Our(More)
BACKGROUND Ichthyophthirius multifiliis, commonly known as Ich, is a highly pathogenic ciliate responsible for 'white spot', a disease causing significant economic losses to the global aquaculture industry. Options for disease control are extremely limited, and Ich's obligate parasitic lifestyle makes experimental studies challenging. Unlike most(More)
Myb domain proteins contain a conserved DNA-binding domain composed of one to four conserved repeat motifs. In animals, Myb proteins are encoded by a small gene family and commonly contain three repeat motifs (R1R2R3); whereas, plant Myb proteins are encoded by a very large and diverse gene family in which a motif containing two repeats (R2R3) is the most(More)
Streptomycetes are filamentous soil-dwelling bacteria. They are best known as the producers of a great variety of natural products such as antibiotics, antifungals, antiparasitics, and anticancer agents and the decomposers of organic substances for carbon recycling. They are also model organisms for the studies of gene regulatory networks, morphological(More)
The combination of cell biology and toxicology (CBTo) demonstrates the potential effects of elements in cellular structures, organelles, functioning properties, metabolic circles, signaling pathways, or interactions with the mi-croenvironment. These elements not only include chemicals and drugs, but one should also consider food, water, and even the air we(More)
Jak (Janus kinase) is a nonreceptor tyrosine kinase, which plays important roles in signal transduction pathways. The unique feature of Jak is that, in addition to a fully functional tyrosine kinase domain (JH1), Jak possesses a pseudokinase domain (JH2). Although JH2 lost its catalytic function, experimental evidence has shown that this domain may have(More)
