    Notes: Abstract The activities of two rat liver lysosomal enzymes, acid phosphatase and β-glucuronidase, undergo changes as a function of animal age. Acid phosphatase activity increases during maturation, but subsequently declines during senescence. β-glucuronidase remains unchanged during maturation, but increases during senescence such that old rats exhibit significantly higher activity than young animals. Acid phosphatase is unaffected by chronic phenobarbital administration, whereas β-glucuronidase is markedly stimulated in young and mature rats and to a lesser extent in senescent animals. The induced activities return to near control levels within two days after withdrawal of the drug, regardless of animal age. These data suggest (1) that these two hepatic lysosomal enzymes undergo different changes, and (2) that the inducibility of β-glucuronidase is diminished as a function of animal age.

    Notes: Abstract The hepatic drug-metabolizing capacities of rodents and humans undergo marked age-dependent declines, particularly between maturity and senescence. This decline probably results from distinct qualitative and quantitative changes in the microsomal mixed function oxidase system. Previous studies reported age-related reductions in the amount of smooth surfaced endoplasmic reticulum membrane and the specific activities of several constituent enzymes of this drug-metabolizing system. The present study has subjected one of these enzymes, NADPH cytochrome c (P-450) reductase, to an extensive analysis and some of these data are reported here. The microsomal membranes of young Fischer 344 male rats (3 months) yielded approximately twice the enzyme recovered from those of old animals (27 months). Furthermore, the specific activity of the purified enzyme isolated from young animals was two-fold higher than that obtained from senescent rats. The “old” enzyme also exhibited an increased thermostability profile in comparison to the “young” enzyme. These data provide the first evidence of possible molecular alterations responsible for the well-documented age-dependent decline in the functional capacity of the rat liver microsomal mixed function oxidase system.

    Topics: Biology
    Notes: Summary The trpE gene from Acinetobacter calcoaceticus encoding the anthranilate synthase component I was cloned, identified by deletion analysis and sequenced. It encodes a predicted polypeptide of 497 amino acids with a calculated molecular weight of 55323. Its primary structure shows 49% identical amino acids with the enzyme from Clostridium thermocellum, 45% with that of Thermus thermophilus and only 35% with that of Escherichia coli. The codon usage of the trpE genes encoding the most homologous enzymes differs greatly indicating selection for amino acid maintainance. The homologies are clustered in the C-terminal 200 amino acids of the sequences indicating that this part is important for enzymic activity.

    Notes: Abstract There is considerable evidence that the mucosal or secretory immune response in the gastrointestinal tract is compromised by aging. The generation of a mucosal immune response is an extremely complex process that involves antigenic stimulation of a specific subpopulation of immunologically competent cells in the Peyer's patches, differentiation and migration of these cells to the small intestinal lamina propria, initiation and regulation of local antibody production in the intestinal wall, and mucosal epithelial cell receptor-mediated transport of antibodies to the intestinal lumen. Available data suggest that gastrointestinal mucosal immunosenescence reflects deficits in: (1) the differentiation and/or migration (homing) of immunoglobulin A immunoblasts to the intestinal lamina propria, and (2) the initiation and/or regulation of local antibody production. The significant age-related increases in the incidence and severity of gastrointestinal infectious diseases, coupled with the potential for immunopharmacologic manipulation of the mucosal immune compartment, substantiate the merit of studies designed to resolve the etiology of mucosal immunodeficiency in the elderly.
