Disease relevance of anf-A

 

High impact information on anf-A

 

Biological context of anf-A

  • The co-localization of dense binding sites for both peptides in the nucleus habenularis, hypophyseal pars nervosa and pars distalis supports the view that ANF and A II have opposite regulatory functions in these regions [5].
  • The osmotic stress of acclimation to 1.5% salt water increased renal but not adrenal ANF binding [6].
 

Anatomical context of anf-A

 

Associations of anf-A with chemical compounds

  • In addition, preincubation with ANF increased the number of oocytes that underwent progesterone-induced maturation [4].
  • Atrial natriuretic factor activates cyclic adenosine 3',5'-monophosphate phosphodiesterase in Xenopus laevis oocytes and potentiates progesterone-induced maturation via cyclic guanosine 5'-monophosphate accumulation [4].
  • These results suggest that ANF potentiates glibenclamide-sensitive K+ currents via the activation of receptor guanylate cyclase and consequent accumulation of cGMP in follicle-enclosed Xenopus oocytes [9].
  • K+ currents induced by the K+ channel opener Y-26763 were potentiated by ANF (0.5-50 nM) in a concentration-dependent manner [9].
  • Only ANF analogues with intact disulfide bridges (rANF(99-126), hANF(99-126), Atriopeptin II, frogANF(21)), and an extract of Xenopus laevis hearts significantly inhibited aldosterone release; the N-terminal (99-109) and the C-terminal ANF(116-126) fragments had no effects [8].
