Chromatography studies on bio-affinity of nine ligands of a1-adrenoceptor to a1D subtypes overexpressed in cell membrane

Copyright by Science in China Press 2004 The a1-AR is present in many tissues including heart, blood vessels, liver, brain, kidney, prostate and spleen. In these tissues, the a1-AR mediates a variety of physiological effects such as neurotransmission, vasoconstriction, cardiacinotropy, chronotropy and glycogenolysis[1]. In 1986, Morrow and Greese pro-posed that a1-AR should be subclassified into two subtypes. Later this hypothesis was proved by Q.D Han in 1987. He not only verified a1-A…     

The complete mitochondrial genomes sequences of Asio flammeus and Asio otus and comparative analysis

Mitochondrial DNA (mtDNA), as a model sys-tem, has been extensively used for molecular phy-logenetic and evolutionary analysis[1]. With the ad-vances in DNA sequencing technology, more andmore researchers prefer to use complete mitochondrialgenome for phylogenetic analysis[2—4]. Since the com-plete sequencing of human mtDNA in 1981 (Andersonet al., 1981)[5], 342 vertebrate mitochondrial genomeshave so far been sequenced. Up to now the completesequences of 29 avian mitochondrial genomes h…

The angiotensin Ⅱ type 1 receptor and receptor-associated proteins

INTRODUCTIONThe renin-angiotensin system (RAS) is consid-ered to be the major regulator of blood pressure)electrolyte balance and renal, neuronal as well as en-docrine functions related to cardiovascular control.The RAS is the key factor in most cases essential hy-pertension, as indicated by successes in treatment ofhypertensive patients with various angiotensin I con-verting enzyme (ACE) inhibitors and receptor block-ers. Renin was a central subject of intense investigation because of…
