Biological context of adenylic acid

• The molecular and structural phenotypes displayed by the double mutants support a model in which the ANP family of MAPKKKs positively regulates cell division and growth and may negatively regulate stress responses [21].
• Moreover, the extensive distribution of 125I-ANP binding sites in mammalian brain suggests that the possible roles of ANP/ANF-like peptides in brain are not restricted to the central regulation of cardiovascular parameters [22].
• ANP and BNP (300 ng) reduced pulmonary artery pressure during acute hypoxia-induced pulmonary vasoconstriction in +/+ mice, but this effect was attenuated in +/- and absent in -/- mice [23].
• The half life of [125I]ANP in the circulation of homozygotes lacking NPRC is two-thirds longer than in the wild type, although plasma levels of ANP and BNP in heterozygotes and homozygotes are close to the wild type [24].
• This includes the A- and B-type natriuretic peptide (ANP and BNP) genes, which encode peptide hormones with crucial roles in the regulation of blood volume and pressure [25].

Anatomical context of adenylic acid

• Examination of macrophages for ANP mRNA showed a similar response to LPS and zymosan, though only a three- to sixfold increase, confirming previous data [15].
• Moreover, EPC's and early erythroid cells also synthesize tRNA and a presumed Hb-mRNA which has been identified by its sedimentation rate at 9-12 s and its content of polyadenylic acid [26].

• The polyadenylic acid selected RNA also showed 8-fold or greater enhancement, showing marked elevation in the level of two major mRNAs, 5.7 and 4.0 kilobases, and two additional minor mRNAs, 2.3 and 1.2 kilobases, as compared with those of a normal human embryonic fibroblast cell line, MRC-5 [29].

Associations of adenylic acid with other chemical compounds

• This rise in glomerular capillary pressure, in turn, resulted from afferent arteriolar vasodilatation and concurrent efferent arteriolar vasoconstriction, findings that proved independent of both endogenous angiotensin II activity and ANP-induced reductions in renal perfusion pressure [30].
• Guanylate cyclase appears to represent a central member of a diverse family of proteins involved in cell signaling mechanisms including the protein kinases, a low Mr ANP receptor, and possibly adenylate cyclase (based on limited sequence identity with the yeast enzyme) [31].
