EJect of Various Lipolytic Hormones on Cyclic AMP Levels in Isolated Fat CellsLipolytic hormones other than epinephrine were capable of stimulating the adenyl cyclase system in isolated fat cells Table I ; . Among these were ACTH, glucagon, thyroidstimulating hormone, luteinizing hormone, and, as would be and the synthetic catecholamine expected, norepinephrine isoproterenol. Agents which were tested but were without significant effect on cyclic AMP levels in isolated fat cells incubated with 1 mu caffeine included prolactin 5 pg per ml ; , Pitressin 1 unit per ml ; , and Pitocin 1 unit per ml ; . Time Course of E$ect of Epinephrine on Cyclic AMP Levels in Isolated Fat Cells-The response of isolated fat cells incubated with 1 m caffeine and 5.5 epinephrine is very rapid Fig. 3 ; . The cyclic AMP level was increased by 30 set, and continued to increase until 6 mm, after which it fell slowly. The level of cyclic AMP was fairly well maintained between 10 and 20 min, and 10 minutes was adopted as the standard incubation time for reasons of convenience and reproducibility. Effect of Increasing Epinephrine and ACTH Concentrations on Cyclic AMP Accumulation by Isolated Fat Cells-Cyclic AMP.

Two of the four brothers developed high-responding inhibitors Table 2 ; . This mutation is located in the A2-domain and has not been reported to the HAMSTeRS database. The mutation affects the donor splice site of exon 13, since the first nucleotide of the glycine codon GGT is the last nucleotide of exon 13. The donor splice score is reduced from 8.1 to 4.2, thus almost abolishing the splice site and causing a severe hemophilia A phenotype, similar to that caused by a serine substitution at the same location reported in the HAMSTeRS database. The S534P and N684D mutations have previously been identified, but not associated with inhibitors.20, 23 Among the remaining missense mutations found in the MIBS families without inhibitors, two mutations were novel, and only R2304C has previously been associated with inhibitors27-29 Table 3.
ITS2 SEQUENCE VARIABILITY OF CYTAUXZOON FELIS IN INFECTED DOMESTIC CATS. H. Moore, D. S. Peterson, K. S. Latimer, and B. E. LeRoy. Department of Pathology and Department of Infectious Diseases, College of Veterinary Medicine, University of Georgia, Athens, GA. Cytauxzoonosis is an emerging, tickborne, hemoprotozoal disease of domestic and exotic cats. The rapid onset of severe illness and high mortality commonly associated with this disease in domestic cats suggest that they likely serve as dead-end hosts. However, recent case studies of infected cats with more moderate clinical signs and improved survival suggest the existence of a less virulent strain of Cytauxzoon felis. We hypothesized that genetic analysis might identify distinct populations of C. felis among infected domestic cats and that this genetic variation may impact disease severity or clinical outcome. Given the fact that the ribosomal internal transcribed spacer ITS ; region is a useful marker for differentiating very closely related species of many pathogens, we assessed genotypic variability by comparing nucleotide sequences of the ITS2 region of C. felis from infected domestic cats. Our initial studies found no significant nucleotide polymorphisms within this region of the parasite's genome. These findings suggest that genetic variation within the ITS2 region of C. felis may not correlate with an observed change in virulence. Further study of the C. felis genome may identify other regions that more closely link genetic variability of the parasite and clinical outcome in parasitized domestic cats and posture.

Density of 0.25 g cc was obtained Fig. 1 ; . The extrusion process was also found to be very stable Table 1 ; . Though the decrease in density was marginal, the average cell size of the compatibilized foamed blend was found to be about 900 m versus about 1500 m for the uncompatibilized foamed blend Fig. 2 ; . The use of the reactive coagent to enhance compatibility had a great effect on both density 0.17 g cc ; and cell size 180 m ; as shown in Figs. 1 and 2. The peak melting temperatures of PET and PP and the % crystallinity of PET were not significantly affected by the addition of compatibilizer as shown in Table 2. However, when the compatibilizer or compatibilizer coagent combination was used, the crystallization peak temperatures of PET and PP were shifted to much lower values. This is presumably the result of enhanced interactions between the blend components delaying their ability to crystallize. These results are in agreement with DSC data reported earlier on PET PP and PET PP-g-AA unfoamed blends 5 and pram.

Region of the phosphoenolpyruvate carboxykinase mRNA 39 ; . The precise mechanism of action of the glucocorticoid-responsive stabilizing element on the phosphoenolpyruvate carboxykinase mRNA has not yet been established, but it is postulated to regulate the polyadenosine tail, a 102-nucleotide stretch of alternating purines and pyrimidines, or an AUUUA motif 39 ; . To determine the effects of glucocorticoids on placental HSD11B2 gene transcription, we transfected trophoblast cells with a luciferase reporter gene construct driven by the HSD11B2 promoter. Our preliminary findings demonstrate that glucocorticoid treatment increases HSD11B2 promoter activity, suggesting that the glucocorticoid-induced increase in placental 11 -HSD2 mRNA is mediated by a dual mechanism involving both an enhanced rate of HSD11B2 gene transcription and increased mRNA stability. It is well established that activated GRs modulate gene transcription by either directly binding to glucocorticoid-response elements GREs ; in target genes or indirectly through interactions with other transcription factors 44 ; . Despite the apparent lack of a GRE consensus sequence within the 4.5-kb HSD11B2 promoter TFSEARCH, version 1.3 ; , it remains possible that activated GRs may interact with a GRE-like sequence in the HSD11B2 promoter to increase gene transcription. Alternately, glucocorticoids may increase the rate of HSD11B2 gene transcription indirectly through protein-protein interactions, with factors such as Sp1 and or Sp3 that have been identified previously as the two critical transcription factors involved in regulating HSD11B2 promoter activity in JEG-3 cells 45, 46 ; . It is noteworthy that a GR-mediated gene transcriptional effect that occurs independently of de novo protein synthesis operating through mechanisms other than traditional GREs has been reported previously 47 ; . Obviously, additional studies will be required to elucidate the precise molecular mechanisms underlying the glucocorticoid-induced upregulation of HSD11B2 gene transcription. Placental 11 -HSD2 expression increases with advancing gestation 13, 14 ; , and this increase coincides with increased circulating glucocorticoid levels in pregnant women 5, 6 ; . In the present study, we provide the first evidence that glucocorticoids increase the expression of 11 -HSD2 in cultured human trophoblast cells. If this occurs in the human placenta in vivo, our findings would suggest that the elevated glucocorticoid levels in maternal circulation may be responsible for increasing the expression of placental 11 -HSD2 across gestation. In humans, single and multiple courses of antenatal glucocorticoid treatment do not appear to be associated with reduced birth weight, contrary to what is seen in several animal models, including mice, rats, and sheep 18 ; . For instance, a single course of maternal glucocorticoid administration in sheep results in 15% reduction in birth weight, with severe growth restriction after multiple courses 48, 49 ; . Although the reasons for the apparent species differences in fetal response to maternal glucocorticoid treatment are unknown, it is tempting to speculate that these differences may be explained partially by the opposite effects of glucocorticoids on placental 11 -HSD2 in humans and sheep. It is conceivable that in humans the glucocorticoid-induced increase in placental 11 -HSD2 could limit fetal exposure to maternally derived glucocorticoid via the placenta. Thus, the auto-regulation of placental 11 -HSD2 by glucocorticoids and pramlintide.
