Longevity is impacted by growth hormone action during early postnatal period.

ABSTRACT: Life-long lack of growth hormone (GH) action can produce remarkable extension of longevity in mice. Here we report that GH treatment limited to a few weeks during development influences the lifespan of long-lived Ames dwarf and normal littermate control mice in a genotype and sex-specific manner. Studies in a separate cohort of Ames dwarf mice show that this short period of the GH exposure during early development produces persistent phenotypic, metabolic and molecular changes that are evident in late adult life. These effects may represent mechanisms responsible for reduced longevity of dwarf mice exposed to GH treatment early in life. Our data suggest that developmental programming of aging importantly contributes to (and perhaps explains) the well documented developmental origins of adult disease.

High nutrient intake during the early postnatal period accelerates skeletal muscle fiber growth and maturity in intrauterine growth-restricted pigs.

Project description:Background:Intrauterine growth-restricted (IUGR) neonates impair postnatal skeletal muscle growth. The aim of this study was to investigate whether high nutrient intake (HNI) during the suckling period could improve muscle growth and metabolic status of IUGR pigs. Methods:Twelve pairs of IUGR and normal birth weight (NBW) pigs (7 days old) were randomly assigned to adequate nutrient intake and HNI formula milk groups. Psoas major (PM) muscle sample was obtained after 21 days of rearing. Results:IUGR decreased cross-sectional areas (CSA) and myofiber numbers, activity of lactate dehydrogenase (LDH), and mRNA expression of insulin-like growth factor 1 (IGF-1), IGF-1 receptor (IGF-1R), mammalian target of rapamycin (mTOR), ribosomal protein s6 (RPS6), eukaryotic translation initiation factor 4E (eIF4E), protein expression of phosphorylated mTOR (P-mTOR), and phosphorylated protein kinase B (P-Akt) in the PM muscle of pigs. Irrespective of birth weight, HNI increased muscle weight and CSA, the concentration of RNA, and ratio of RNA to DNA, as well as ratio of LDH to ?-hydroxy-acyl-CoA-dehydrogenase in the PM muscle of pigs. Furthermore, HNI increased percentages of MyHC IIb, mRNA expression of IGF-1, IGF-1R, Akt, mTOR, RPS6, and eIF4E, as well as protein expression of P-mTOR, P-Akt, P-RPS6, and P-eIF4E in the PM muscle of pigs. Conclusion:The present findings suggest that high nutrient intake during the suckling period could improve skeletal muscle growth and maturity, which is associated with increasing the expression of protein deposition-related genes and accelerating the development of glycolytic-type myofiber in pigs.

Spinal manifestations of CLN1 disease start during the early postnatal period.

Project description:AimTo understand the progression of CLN1 disease and develop effective therapies we need to characterize early sites of pathology. Therefore, we performed a comprehensive evaluation of the nature and timing of early CLN1 disease pathology in the spinal cord, which appears especially vulnerable, and how this may affect behaviour.MethodsWe measured the spinal volume and neuronal number, and quantified glial activation, lymphocyte infiltration and oligodendrocyte maturation, as well as cytokine profile analysis during the early stages of pathology in Ppt1-deficient (Ppt1-/- ) mouse spinal cords. We then performed quantitative gait analysis and open-field behaviour tests to investigate the behavioural correlates during this period.ResultsWe detected significant microglial activation in Ppt1-/- spinal cords at 1 month. This was followed by astrocytosis, selective interneuron loss, altered spinal volumes and oligodendrocyte maturation at 2 months, before significant storage material accumulation and lymphocyte infiltration at 3 months. The same time course was apparent for inflammatory cytokine expression that was altered as early as one month. There was a transient early period at 2 months when Ppt1-/- mice had a significantly altered gait that resembles the presentation in children with CLN1 disease. This occurred before an anticipated decline in overall locomotor performance across all ages.ConclusionThese data reveal disease onset 2 months (25% of life-span) earlier than expected, while spinal maturation is still ongoing. Our multi-disciplinary data provide new insights into the spatio-temporal staging of CLN1 pathogenesis during ongoing postnatal maturation, and highlight the need to deliver therapies during the presymptomatic period.

Serum protein electrophoretic pattern in piglets during the early postnatal period.

Project description:The pattern of serum proteins, the typical features of the electrophoretogram in newborn piglets and during their postnatal development is not completely described. Therefore, the aim of this study was to characterize the changes in serum protein electrophoretic pattern and features of the electrophoretograms during the early postnatal period. Significant changes during the monitored period were found in all evaluated parameters (P < 0.001). The most marked changes were observed mainly in the period before weaning. The concentrations of total proteins, albumin and γ-globulins were before colostrum intake low, γ-globulins represented the smallest proportion of protein fractions. The proportion of α1-globulins was after birth a dominant protein fraction. Significant increase of total proteins, α2-, β- and γ-globulins and decrease of α1-globulins was found 2 days after colostrum intake. The albumin and A/G values increased after birth gradually until weaning. After weaning a significant changes were found in absolute concentrations of total protein and albumin, and in relative values of β-globulin fractions. Presented results showed marked developmental alterations in the serum protein pattern in piglets along with the age. The study also brings new knowledge in the field of description of typical features of electrophoretograms in the observed period of piglet's life.

Microglia response to allergic airway inflammation during early postnatal period in mice

Project description:We examined how allergic inflammation in early postnatal period influences microglia using a short- and long-term airway allergy model. Male mice (C57BL/6) were immunized by intraperitoneal injection with aluminum hydroxide and ovalbumin (OVA) or phosphate-buffered saline (PBS) (control) at postnatal days (P) 3, 7, and 11, followed by intranasal challenge with OVA or PBS solution twice a week until P30 or P70. Microglia from whole brain were isolated from PBS- and OVA-treated mice by gating on CD11b+CD45int cells with flowcytometry at P30 and P70 respectively. Results suggest the dysregulation of microglial genes related to synaptic pruning and clearance, aging, and corticosteroid pathway and distinction between short- and long- term allergen challenge.

Neonatal and maternal serum creatinine levels during the early postnatal period in preterm and term infants.

Project description:We investigated the relationship of neonatal and maternal serum creatinine (nSCr and mSCr, respectively) with various maternal/infant characteristics at different gestational ages (GA). We reviewed medical records of neonates admitted to NICU. We collected data on birth weight, GA, Apgar scores, medications, etc. Spearman's test was used to analyze the correlation between serum creatinine and continuous variables, and the Mann-Whitney U and Kruskal-Wallis tests for continuous variables between groups. The changes in nSCr, mSCr, and nSCr/mSCr ratio because of gestational age and the points in gestational changes in trends were estimated using joinpoint trend analysis. From 614 neonate and mother pairs, we found that nSCr was significantly correlated with GA. However, mSCr at >28 wks decreased with GA. The nSCr/mSCr ratio was correlated with GA. In infants born <29 weeks, pregnancy-induced hypertension (PIH) (p = 0.000, β = 0.20) and mSCr (p = 0.000, β = 0.73) were significantly associated with nSCr. In term infants, maternal magnesium administration (p = 0.000, β = 0.25), respiratory distress syndrome (p = 0.013, β = 0.16), PIH (p = 0.005, β = 0.19), and mSCr (p = 0.000, β = 0.33) were significantly associated with nSCr. nSCr reflected mSCr at all gestational ages. The correlation between nSCr and mSCr in preterm infants (p = 0.000, β = 0.74) was stronger than in term infants (p = 0.000, β = 0.34).

Early life growth hormone treatment shortens longevity and decreases cellular stress resistance in long-lived mutant mice.

Project description:Hypopituitary Ames dwarf mice were injected either with growth hormone (GH) or thyroxine for a 6-wk period to see whether this intervention would reverse their long life span or the resistance of their cells to lethal stresses. Ames dwarf mice survived 987 ± 24 d (median), longer than nonmutant control mice (664 ± 48), but GH-injected dwarf mice did not differ from controls (707 ± 9). Fibroblast cells from Ames dwarf mice were more resistant to cadmium than cells from nonmutant controls (LD(50) values of 9.98 ± 1.7 and 3.9 ± 0.8, respectively), but GH injections into Ames dwarf mice restored the normal level of cadmium resistance (LD(50)=5.8 ± 0.9). Similar restoration of normal resistance was observed for fibroblasts exposed to paraquat, methyl methanesulfonate, and rotenone (P<0.05 in each case for contrast of GH-treated vs. untreated dwarf mice; P<0.05 for dwarf vs. nonmutant control mice.) T4 injections into Ames dwarf mice, in contrast, did not restore normal life span. We conclude that the remarkable life-span extension of Ames dwarf mice, and the stress resistance of cells from these mice, depends on low levels of GH exposure in juvenile and very young adult mice.

The hormonal action of IGF1 in postnatal mouse growth.

Project description:The mammalian insulin-like growth factor 1 (IGF1), which is a member of a major growth-promoting signaling system, is produced by many tissues and functions throughout embryonic and postnatal development in an autocrine/paracrine fashion. In addition to this local action, IGF1 secreted by the liver and circulating in the plasma presumably acts systemically as a classical hormone. However, an endocrine role of IGF1 in growth control was disputed on the basis of the results of a conditional, liver-specific Igf1 gene knockout in mice, which reduced significantly the level of serum IGF1, but did not affect average body weight. Because alternate interpretations of these negative data were tenable, we addressed genetically the question of hormonal IGF1 action by using a positive experimental strategy based on the features of the cre/loxP recombination system. Thus, we generated bitransgenic mice carrying in an Igf1 null background a dormant Igf1 cDNA placed downstream of a transcriptional "stop" DNA sequence flanked by loxP sites (floxed) and also a cre transgene driven by a liver-specific promoter. The Igf1 cDNA, which was inserted by knock-in into the mutated and inactive Igf1 locus itself to ensure proper transcriptional regulation, was conditionally expressed from cognate promoters exclusively in the liver after Cre-mediated excision of the floxed block. Our genetic study demonstrated that the endocrine IGF1 plays a very significant role in mouse growth, as its action contributes approximately30% of the adult body size and sustains postnatal development, including the reproductive functions of both mouse sexes.

Genistein exposure during the early postnatal period favors the development of obesity in female, but not male rats.

Project description:Genistein (Gen), the primary isoflavone in soy, has been shown to adversely affect various endocrine-mediated endpoints in rodents and humans. Soy formula intake by human infants has been associated with early age at menarche and decreased female-typical behavior in girls. Adipose deposition and expansion are also hormonally regulated and Gen has been shown to alter these processes. However, little is known about the impact of early-life soy intake on metabolic homeostasis in adulthood. The current study examined the impact of early-life Gen exposure on adulthood body composition (by magnetic resonance imaging) and the molecular signals mediating adipose expansion. From postnatal day (PND) 1 to 22, rat pups were daily orally dosed with 50mg/kg Gen to mimic blood Gen levels in human infants fed soy formula. Female but not male Gen-exposed rats had increased fat/lean mass ratio, fat mass, adipocyte size and number, and decreased muscle fiber perimeter. PND22 Gen-exposed females, but not males, had increased expression of adipogenic factors, including CCAAT/enhancer binding protein alpha (Cebpα), CCAAT/enhancer binding protein beta (Cebpβ), and peroxisome proliferator-activated receptor gamma (Pparγ). Furthermore, Wingless-related MMTV integration site 10b (Wnt10b), a critical regulator of adipogenic cell fate determination, was hypermethylated and had decreased expression in adipose of PND22 Gen-exposed females. These data suggest that developmental Gen exposure in rats has gender-specific effects on adiposity that closely parallel the effects of a postweaning high-fat diet and underscore the importance of considering timing of exposure and gender when establishing safety recommendations for early-life dietary Gen intake.
