| pubmed-article:8014385 | pubmed:abstractText | The biochemical locus of the decrease of lipolytic responsiveness to catecholamines in the aging rat has not heretofore been completely identified. Although increased sensitivity to the inhibitory action of adenosine is the likely explanation for the decrease during maturation, the nature of the age effect during senescence has been unclear. In order to determine whether the proximal or distal portion of the lipolytic pathway is involved, we have studied the lipolytic effect of the distally acting cyclic AMP analogue, 8-(4-chlorophenylthioadenosine)3'5'-monophosphate (cyclic) (Cl-cAMP) on rat fat cells from both the epididymal and perirenal fat pads of mature (6 mo) and senescent (24 mo) Fischer 344 rats. Using an adenosine (N6-1-2-phenylisopropyl-adenosine; PIA) regulated system, the lipolytic response to epinephrine (glycerol release) was measured simultaneously with that to Cl-cAMP. The effects of age on lipolysis are greatly influenced by the anatomic site of origin of the fat cells. The epididymal cells of the old rats showed no decreased responsiveness to either epinephrine or Cl-cAMP. However, the perirenal cells of the old rats showed a grossly impaired maximal response to both epinephrine (60% decrease relative to young; p < .005) and Cl-cAMP (42% and 58% decrease in 2 sets of experiments; p < .05 and .04, respectively). Although decreased lipolytic response to epinephrine in epididymal cells was not seen in these studies, this has been clearly shown in earlier work, suggesting that diminished response to epinephrine is demonstrable only when the system is not already maximally inhibited by PIA.(ABSTRACT TRUNCATED AT 250 WORDS) | lld:pubmed |
