12-Hydroxyeicosatetraenoic acid (12-HETE) is formed from arachidonic acid either by 12-lipoxygenase or by a cytochrome P450 monooxygenase. 12-Lipoxygenase is generally localized in the soluble cytosolic fraction, and the cytochrome P450 monooxygenase is a microsomal enzyme. In this study, 12-HETE biosynthesis and the regulation of 12-HETE biosynthesis by epidermal growth factor (EGF) in A431 ce...

Coral reefs, the most biodiverse habitats in ocean, are formed by anthozoan cnidarians, scleractinian corals. Recently, however, ongoing climate change has imperiled corals and coral reef environments changing drastically. Thus, convenient, high-density monitoring of is essential to understand changes communities. Environmental DNA (eDNA) metabarcoding potentially one effective means achieving ...

Author manuscript, published in "Molecular Phylogenetics and Evolution 28, 2 (2003) 261-75" Delsuc et al. Molecular systematics of armadillos 2 ABSTRACT The thirty living species of armadillos, anteaters and sloths (Mammalia: Xenarthra) represent one of the three major clades of placentals. Armadillos (Cingulata: Dasypodidae) are the earliest and most speciose xenarthran lineage with twenty-one...

Angiotensin II (Ang II) elicits an Ang II type 2 (AT2) receptor-mediated increase in delayed-rectifier K+ current (IK) in neurons cultured from newborn rat hypothalamus and brainstem. This effect involves a pertussis toxin (PTX)-sensitive Gi protein and is abolished by inhibition of serine and threonine phosphatase 2A (PP-2A). Here, we determined that Ang II stimulates [3H]arachidonic acid (AA)...

The adenovirus 12S and 13S E1A proteins have been shown to relieve repression mediated by the cellular transcription factor YY1. The 13S E1A protein not only relieves repression but also activates transcription through YY1 binding sites. In this study, using a variety of in vivo and in vitro assays, we demonstrate that both E1A proteins can bind to YY1, although the 13S E1A protein binds more e...
