Physical and functional interaction between p53 and the Werner's syndrome protein. (1/201)

Werner's syndrome is a human autosomal recessive disorder leading to premature aging. The mutations responsible for this disorder have recently been localized to a gene (WRN) encoding a protein that possesses DNA helicase and exonuclease activities. Patients carrying WRN gene mutations exhibit an elevated rate of cancer, accompanied by increased genomic instability. The latter features are also characteristic of the loss of function of p53, a tumor suppressor that is very frequently inactivated in human cancer. Moreover, changes in the activity of p53 have been implicated in the onset of cellular replicative senescence. We report here that the WRN protein can form a specific physical interaction with p53. This interaction involves the carboxyl-terminal part of WRN and the extreme carboxyl terminus of p53, a region that plays an important role in regulating the functional state of p53. A small fraction of WRN can be found in complex with endogenous p53 in nontransfected cells. Overexpression of WRN leads to augmented p53-dependent transcriptional activity and induction of p21(Waf1) protein expression. These findings support the existence of a cross-talk between WRN and p53, which may be important for maintaining genomic integrity and for preventing the accumulation of aberrations that can give rise to premature senescence and cancer.  (+info)

Unique mutations in mitochondrial DNA of senescence-accelerated mouse (SAM) strains. (2/201)

Mitochondrial DNA (mtDNA) is exclusively inherited maternally and hence could offer a good method for tracing the lineage of mouse strains. We examined the mtDNA sequence of senescence-accelerated mouse (SAM) strains as well as other laboratory strains of inbred mice to deduce the ancestral strain of SAM. Four unique mutations were identified at bases 2256, 10,847, 11,181, and 13,053 in SAM strains. The mutations were not found in other mouse strains including AKR/J, one of the parental strains of SAM. Comparison of the mtDNA sequences also led to the consensus mtDNA sequence of laboratory strains of inbred mice. The seven laboratory strains of common inbred mice showed polymorphisms at base 9348, thymine repeat from base 9818, and adenine repeat from base 9821, and could be classified into five types by combination of the differences. Although we could not identify mouse strains with the same type of mtDNA as SAM in this study, the polymorphisms would provide a promising clue to ascertain the ancestral strain(s) of SAM. The polymorphism in mtDNA could be used to ascertain the genealogy of other mouse strains as well.  (+info)

Antioxidant systems in tissues of senescence accelerated mice. (3/201)

Significant decrease in the level of lipid antioxidants (measured from the kinetics of the induced chemiluminescence in brain homogenate) and of the hydrophilic antioxidant carnosine as well was observed in the brain of 14-16-month-old mice of SAMP1 line, which is characterized by accelerated accumulation of senile features, in comparison with the control line SAMR1. In the brain of SAMP1 animals the activity of cytosolic Cu/Zn-containing superoxide dismutase (SOD) was reduced, while the activity of membrane-bound Mn-SOD was at an extremely low level. The activity of glutathione-dependent enzymes (glutathione peroxidase, glutathione reductase, and glutathione transferase) did not differ in the brain of SAMP1 and SAMR1 animals, and catalase activity was similarly low in both cases. At the same time, excess concentration of excitotoxic compounds, significantly exceeding that for the control line, was determined in the brain and blood of SAMP1 animals. The activity of glutathione enzymes in liver and heart as well as the activity of cytosolic Cu/Zn-SOD in liver did not differ in the two studied lines, while the activity of erythrocyte glutathione peroxidase was slightly increased, and the activity of liver catalase and erythrocyte Cu/Zn-SOD was significantly decreased for SAMP1 compared with SAMR1. The results demonstrate that the accelerated ageing of SAMP1 animals is connected to a significant extent with the decreased efficiency of the systems utilizing reactive oxygen species (ROS) in tissues.  (+info)

Association of human aging with a functional variant of klotho. (4/201)

Mice deficient in Klotho gene expression exhibit a syndrome resembling premature human aging. To determine whether variation in the human KLOTHO locus contributes to survival, we applied two newly characterized polymorphic microsatellite markers flanking the gene in a population-based association study. In a cohort chosen for its homogeneity, Bohemian Czechs, we demonstrated significant differences in selected marker allele frequencies between newborn and elderly individuals (P < 0.05). These results precipitated a search for functional variants of klotho. We identified an allele, termed KL-VS, containing six sequence variants in complete linkage disequilibrium, two of which result in amino acid substitutions F352V and C370S. Homozygous elderly individuals were underrepresented in three distinct populations: Bohemian Czechs, Baltimore Caucasians, and Baltimore African-Americans [combined odds ratio (OR) = 2.59, P < 0.0023]. In a transient transfection assay, secreted levels of klotho harboring V352 are reduced 6-fold, whereas extracellular levels of the S370 form are increased 2.9-fold. The V352/S370 double mutant exhibits an intermediate phenotype (1.6-fold increase), providing a rare example of intragenic complementation in cis by human single nucleotide polymorphisms. The remarkable conservation of F352 among homologous proteins suggests that it is functionally important. The corresponding substitution, F289V, in the closest human klotho paralog with a known substrate, cBGL1, completely eliminates its ability to cleave p-nitrophenyl-beta-D-glucoside. These results suggest that the KL-VS allele influences the trafficking and catalytic activity of klotho, and that variation in klotho function contributes to heterogeneity in the onset and severity of human age-related phenotypes.  (+info)

Life span and renal morphological characterization of the SAMP1//Ka mouse. (5/201)

The senescence-accelerated-mouse prone 1 (SAMP1) is considered to be a model of accelerated senility and it also develops severe kidney damage. The SAMP1//Ka mouse is a specific pathogen free (SPF) subline of SAMP1. The present study examined the life span of the SAMP1//Ka mouse and morphologically investigated the kidneys of this animal at 3, 4, 5, 9, 12, 15, 18 and 24 months of age. Males survived for an average of 25 months and females for 28 months. The median lifespan was 18 months for males and 20 for females. Focal cell infiltration and thickening of the basement membrane in the glomerular capsules or tubules appeared from 4 months of age. At 12 months old, glomerular lesions with expansion of the mesangial matrix and thickening of the basement membrane as well as scar lesions in the outer cortex appeared, and amyloid was deposited in the interstitium or glomeruli from 18 months of age. Morphometrically, although the area of the kidney sections was increased at 24 months of age, the diameter of the renal corpuscles, the number of nuclei of the proximal convoluted tubules and the percentage of renal corpuscles with a cuboidal glomerular capsule did not change with age. The results of the present study indicate that the life span of the SAMP1//Ka is increased and that their age-related renal changes differ from those of the original SAMP1.  (+info)

Premature aging in mice deficient in DNA repair and transcription. (6/201)

One of the factors postulated to drive the aging process is the accumulation of DNA damage. Here, we provide strong support for this hypothesis by describing studies of mice with a mutation in XPD, a gene encoding a DNA helicase that functions in both repair and transcription and that is mutated in the human disorder trichothiodystrophy (TTD). TTD mice were found to exhibit many symptoms of premature aging, including osteoporosis and kyphosis, osteosclerosis, early greying, cachexia, infertility, and reduced life-span. TTD mice carrying an additional mutation in XPA, which enhances the DNA repair defect, showed a greatly accelerated aging phenotype, which correlated with an increased cellular sensitivity to oxidative DNA damage. We hypothesize that aging in TTD mice is caused by unrepaired DNA damage that compromises transcription, leading to functional inactivation of critical genes and enhanced apoptosis.  (+info)

Ageing: repair and transcription keep us from premature ageing. (7/201)

Insufficient interleukin-2 production from splenic CD4+ T cells causes impaired cell proliferation and early apoptosis in SAMP1, a strain of senescence-accelerated mouse. (8/201)

We examined the proliferative and cytokine-producing activities of CD4+ T cells from young mice of the senescence-accelerated mouse strain SAMP1, which had shown markedly low T-dependent antibody-producing responses. When splenic T cells were cultured with concanavalin A (Con A), the percentage of CD4+ cells decreased earlier in SAMP1 than in C3H/He mice. At 40 hr of culture, the percentage of BrdU-labelled proliferating CD4+ cells increased strongly in C3H/He, but only slightly in SAMP1. When purified CD4+ T cells were cultured with Con A, the percentage of 5-bromo-2'-deoxyuridine (BrdU)-labelled cells peaked at around 48 hr of culture in both strains, but decreased significantly at 64 hr in SAMP1. The production of interleukin (IL)-2 but not IL-4 or interferon-gamma (IFN-gamma) was significantly lower in SAMP1 than in C3H/He at 48 hr of culture. IL-2 production was also markedly low in SAMP1, even under the stimulation of anti-CD3 with anti-CD28 antibodies. The frequency of cells producing IL-2 was significantly lower in SAMP1 than in C3H/He at 6-24 hr of culture with Con A. The percentage of annexin-positive and propidium iodide (PI)-negative apoptotic cells was significantly higher in SAMP1 than in C3H/He at 96 hr of culture. Exogenous IL-2 prevented the decrease in BrdU-labelled cells and the increase in apoptotic cells in the SAMP1 cell culture. These results indicate that SAMP1 CD4+ T cells cannot produce IL-2 at levels sufficient to support cell proliferation and survival. This may account for the weak T-dependent antibody response in SAMP1 mice.  (+info)

Mitochondria are small powerhouse organelles that have their own DNA, the mitochondrial DNA (mtDNA). For almost half a century, mitochondrial DNA mutations and oxidative stress have been asserted as major contributors to aging, as postulated in the mitochondrial theory of aging published in the 1970s. The theory has been tested on the mtDNA Mutator mice that have an inactive DNA repair mechanism. These mice accumulate mtDNA mutations and present with accelerated aging, which has led scientists to believe that mtDNA mutagenesis drives aging. However, despite rigorous studies by several groups, no one has been able to show that the Mutator mice would present elevated oxidative stress. The prematurely-ageing Mutator mice harbour a defective polymerase-gamma enzyme and present with pronounced mtDNA mutagenesis. Despite the existence of other mouse models with equivalent mtDNA mutagenic propensity, the Mutator mouse model is the only one manifesting accelerated aging. Furthermore, progeria is not a ...
As PS1 is an integral protein of the γ-secretase complex, its stoichiometry may play an important role in balanced processing of APP. A decrease in PS1 (Refolo et al., 1999) or inactivation by mutations (Sudoh et al., 1998) may be associated with increased Aβ42. We had previously noticed an increase in APP as well as Aβ1-42 with age in SAMP8 mice (Morley et al., 2000), suggesting that a decrease in PS1 may cause increased aberrantγ -secretase activity. Accumulation of Aβ is attributed to loss of memory, as reduction of APP expression reverses this loss (Kumar et al., 2000). Therefore, reduction in APP expression is one of the pharmaceutical approaches to counter age-dependent or neurodegenerative disorders like AD that involve memory loss. Being an essential component of γ-secretase, PS1 is another therapeutic target for reducing Aβ formation. As SAMP8 mice have been shown to exhibit memory loss at a relatively early age (Flood and Morley, 1998; Miyamoto, 1997), we have studied the ...

While the effects of inflammaging can seem quite daunting, there are a few things you can do to help protect yourself and perhaps even delay or negate inflammaging. Even if inflammaging has gotten to the point of disease, changes can be made to improve symptoms, many of which are within easy grasp. For example, both diet and exercise are known factors in the creation and elimination of a chronic inflammatory state. Adipose fat can increase inflammation, while maintaining a healthy weight and age appropriate diet can help to prevent it. Exercise, even light exercise for short periods, can also have a profound effect on inflammaging and other chronic inflammatory states. Even 60 minutes per week of moderate exercise can have a positive impact and increase longevity by 18%. The body has a method to help control runaway inflammation - the vagus nerve. The vagus nerve is the anti-inflammatory nerve of the body and controls part of the parasympathetic nervous system (the rest and digest system of ...
In 2000, Franceschi et al. coined the term inflammaging in order to refer to a low-grade pro-inflammatory status appearing during the aging process. They emphasized the role of macrophages as well as cellular stress and genetic factors in the generation of the inflammaging condition. In addition, they hypothesized that this inflammatory environment could predispose the organism to the development of several age-related diseases. During recent years, this scenario has been confirmed by a plethora of experimental evidence. ... Interestingly, the aging process is simultaneously accompanied by both the features accelerating inflammaging and the counteracting, so-called anti-inflammaging characteristics. It seems that the balance between these opposite forces controls the outcome of the aging process, either leading to frailty and degenerative diseases or a healthy old age and longevity. .... The aging process is associated with a decline in autophagic capacity which impairs cellular housekeeping, ...

Abstract: : Purpose: To determine the effect of orally administered genistein on the blue light damage of retina within the senescence-accelerated mouse(SAM)at 28 weeks of exposure Methods: The blue light exposure was set up according to Gottsch et al (Arch Ophthalmol 1993;111:126). Forty-eight SAM P8 mice were divided into four groups. Within each group, the mice were exposed to continuous blue light. One group received a normal, genistein-free diet, one a fatty diet, one a fat+genistein diet, and one a genistein-rich diet. The mice were treated in this fashion for 28 weeks, beginning 4 weeks after birth. The effect of genistein was evaluated using electron microscopy at this specific time. Results: After 28 weeks, using electron microscopy, P8 mice receiving constant blue light and a fatty diet showed a significant thickening of Bruchs membrane and an increase in RPE-deposits compared with the mice receiving the other diet groups. Those with the pure fat diet showed atrophy of the ...

Aging is the single most important prognostic factor associated with the development of many diseases including cancer (1). The results described here demonstrate that aging-associated increases in inflammation negatively impact the development and function of B progenitor cells, including reductions in key indicators of cell fitness. Importantly, using two different, naturally occurring molecules to reduce inflammation in old mice, we show that preventing aging-associated reductions in B progenitor fitness abrogates selection for NRASV12-initiated progenitors. These studies highlight how inflammation-induced alterations in the adaptive landscape in old age govern the selection of oncogenically initiated cells and, ultimately, leukemogenesis within hematopoietic progenitor cell populations (Figure 8D).. In recent years, there has been growing interest in identifying factors that regulate the aging process (8, 52, 53). We observed aging-associated increases in TNF-α, IL-6, and IL-1β levels in ...

Hutchinson-Gilford progeria syndrome (HGPS) is a rare human genetic disease that leads to a severe premature ageing phenotype, caused by mutations in the LMNA gene. The LMNA gene codes for lamin-A and lamin-C proteins, which are structural components of the nuclear lamina. HGPS is usually caused by a de novo C1824T mutation that leads to the accumulation of a dominant negative form of lamin-A called progerin. Progerin also accumulates physiologically in normal ageing cells as a rare splicing form of lamin-A transcripts. From this perspective, HGPS cells seem to be good candidates for the study of the physiological mechanisms of ageing. Progerin accumulation leads to faster cellular senescence, stem cell depletion and the progeroid phenotype. Tissues of mesodermic origin are especially affected by HGPS. HGPS patients usually have a bad quality of life and, with current treatments, their life expectancy does not exceed their second decade at best. Though progerin can be expressed in almost any tissue,
Aging affects all people and is a complex process involving both genetic and environmental factors in a way that is not yet completely understood. Studies of premature aging syndromes might be helpful to acquire further clues to understand the molecular mechanisms explaining how aging occurs. Hutchinson-Gilford progeria syndrome (HGPS or progeria) is a genetic disease causing segmental premature aging in children, with an approximated incidence of 1 in 20 million individuals. Children affected by progeria appear normal at birth, but they begin developing symptoms of disease within the first years of life. Symptoms of HGPS include severe growth retardation, scleroderma-like skin changes, bone and tooth abnormalities, and loss of hair and body fat. The children with progeria die prematurely at a median age of 14.6 years, due to complications from cardiovascular disease and atherosclerosis ...
textbf{BACKGROUND}$: Hutchinson-Gilford progeria syndrome (HGPS) is a fatal sporadic autosomal dominant premature ageing disease caused by single base mutations that optimise a cryptic splice site within exon 11 of the $\textit{LMNA}$ gene. The resultant disease-causing protein, progerin, acts as a dominant negative. Disease severity relies partly on progerin levels. $\textbf{METHODS AND RESULTS}$: We report a novel form of somatic mosaicism, where a child possessed two cell populations with different HGPS disease-producing mutations of the same nucleotide-one producing severe HGPS and one mild HGPS. The proband possessed an intermediate phenotype. The mosaicism was initially discovered when Sanger sequencing showed a c.1968+2T,A mutation in blood DNA and a c.1968+2T,C in DNA from cultured fibroblasts. Deep sequencing of DNA from the probands blood revealed 4.7% c.1968+2T,C mutation, and 41.3% c.1968+2T,A mutation. $\textbf{CONCLUSIONS}$: We hypothesise that the germline mutation was ...

Progeria is a rare genetic condition characterized by an appearance of accelerated aging in children. Its name is derived from the Greek and means prematurely old. The classic type is the Hutchinson-Gilford Progeria Syndrome which was first described in England in 1886 by Dr. Jonathan Hutchinson and again in 1886 and 1904 by Dr. Hastings Gilford.
The vascular pathology of HGPS has puzzled physicians and biomedical investigators for decades (8, 40, 41). Despite an absence of the typical risk factors for atherosclerosis, children with HGPS succumb to heart attacks or stroke, a consequence of occlusions in the coronary and cerebral arteries (52, 53). The arterial pathology in HGPS must be caused by progerin, but the underlying mechanisms have remained unclear. In the current studies, we investigated the vascular pathology in HGPS mice and developed three insights into pathogenesis. The first relates to why the aorta develops disease while other tissues are spared. We found that the aorta produces more progerin than any other tissue-more than the skin and bone (two tissues affected by HGPS) and ~15-fold more than the kidney (an unaffected tissue). Electron micrographs of aortic SMCs of HGPS mice revealed striking abnormalities-intranuclear membrane vesicles and vacuoles in the cytoplasm. The second insight is that mechanical forces influence ...
My laboratory is interested in why and how we age. Specifically, we focus on studying molecular mechanisms of Hutchinson-Gilford progeria syndrome (HGPS), a premature aging disease, and exploring the potential connections between HGPS and normal aging. Children with HGPS die at their early teens due to heart attack or stoke. Approximately 90% of the HGPS cases are causedby a de novo mutation at 1824 position of the lamin A gene (C1824T, G608G). This mutation does not affect the coded amino acid, but partially activates a cryptic splice donor site in the exon 11, leading to the production of a mutant lamin A mRNA that contains an internal deletion of 150 base pairs. This is then translated into a lamin A mutant protein missing 50 amino acids near the C-terminus, termed progerin. ...
1219 Disorazole C1 is a potent, cytotoxic natural product, with IC50 values of , 20 nM in a variety of cancer cell lines. The addition of disorazole C1 disrupted microtubules in cells as early as 24 h after treatment, causing multinucleation and disorganized microtubules at interphase and misaligned chromosomes at the metaphase plate during mitosis. A549 cells that survived a 7 day treatment of disorazole C1 displayed an enlarged, flattened morphology similar to senescent cells treated with doxorubicin. These surviving cells displayed the characteristic β-galactosidase staining at pH 6.0 seen in senescent cells and changes in cell cycle markers indicative of premature or hypermitogenic senescence. A549 cells treated with the IC50 concentration of disorazole C1 (2 nM) for 7 days had increased protein levels of cyclin D, p53 and cyclin-dependent kinase inhibitor p21 as detected by Western blot. This resulted in decreased phosphorylation of Rb (Ser780) and a decrease in total Rb protein levels. A ...
We previously reported that the dried peel powder of Citrus kawachiensis, one of the citrus products of Ehime, Japan, exerted anti-inflammatory effects in the brain of a lipopolysaccharide-injected systemic inflammation animal model. Inflammation is one of the main mechanisms underlying aging in the brain; therefore, we herein evaluated the anti-inflammatory and other effects of the dried peel powder of C. kawachiensis in the senescence-accelerated mouse-prone 8 (SAMP8) model. The C. kawachiensis treatment inhibited microglial activation in the hippocampus, the hyper-phosphorylation of tau at 231 of threonine in hippocampal neurons, and ameliorated the suppression of neurogenesis in the dentate gyrus of the hippocampus ...

A mutant protein responsible for Hutchinson-Gilford Progeria syndrome (HGPS) bars large proteins from entering the nucleus, according to a study in The Journal of Cell Biology.
2005). These secreted molecules affect nearby cells to provoke inflammatory responses, eventually producing aging-related chronic inflammation called inflammaging, one type of sterile persistent inflammation. Thus, long-term stimulation by SASP molecules induces various metabolic changes including cardiovascular changes (Franceschi and Campisi, 2014). Sometimes they lead to late-stage cancer (Campisi, 2013). Thus, blocking SASP production may be effective for achieving healthy aging. Many laboratories have been searching for agents to prevent the aging process itself. However, in our opinion, stopping cellular senescence may have other harmful effects on the body. Blocking cells to go into senescence cells means that they still have proliferating capacity, although they are old. This may deleteriously lead to cancer formation. In this respect, inhibition of SASP formation without affecting aging capacity (inhibition of inflammaging) seems to be a safe new target for healthy aging. To prove the ...

Progerias striking features resemble the aging process put on fast-forward and afflicted people rarely live beyond 13 years. Almost all of the patients die from complications of arteriosclerosis-the clogging or hardening of arteries or blood vessels caused by plaques-which leads to heart attack and stroke. Scientists are particularly interested in progeria in the hopes that it might reveal clues to the normal human aging process. However, the disease is exceedingly rare and only 64 children living with progeria are known making access to patients very difficult. Hutchinson-Gilford progeria is caused by a single point mutation in the gene encoding lamin A, which forms a protein scaffold on the inner edge of the nucleus that helps maintain chromatin structure and organize nuclear processes such as RNA and DNA synthesis. The mutation creates an alternative splice site that leads to the production of a truncated version of the protein known as progerin. Unlike the full-length protein, progerin does ...

  • To gain insight into the origin of cellular senescence and human aging, we analyzed the dependence of sister chromatid exchange (SCE) frequencies on location [i.e., genomic (G-SCE) vs. telomeric (T-SCE) DNA] in primary human fibroblasts deficient in WRN, BLM, or ERCC1-XPF. (
  • Premature cellular senescence may act as a powerful tumor-suppressor mechanism in telomerase-deficient cells with mutations that cause T-SCE levels to rise. (
  • Furthermore, T-SCE-driven premature cellular senescence may be a factor contributing to accelerated aging in Werner and Bloom syndromes, but not XFE progeroid syndrome. (
  • Defects in the spns1 (Sphingolipid Transporter 1 (putative))gene were found to lead to senescence in the developing embryos and premature ageing in adults. (
  • Furthermore, Cdc42 activation is sufficient to promote a premature cellular senescence phenotype that depends on p53. (
  • and premature senescence. (
  • Our results present an interesting possibility linking Cdc42 activity to genome maintenance, cellular senescence regulation, and mammalian aging. (
  • To demonstrate that myocardial senescence is promoted by loss of Pim leading to premature aging and aberrant mitochondrial function. (
  • A pilot study of premature ovarian senescence: I. Correlation of triple CGG repeats on FMR1 gene to ovarian reserve parameters FSH and AMH. (
  • Now researchers from the University of Pennsylvania have pinpointed a molecular link between DNA damage, cellular senescence and premature aging. (
  • One of the reasons senescence is believed to lead to the characteristic changes of aging is that it affects stem cells, which normally serve to replenish populations of healthy cells. (
  • Now that you understand that premature aging, we can apply the same principles to regular aging, which simply reflects loss of data integrity made possible by telomere attrition (both from replicative senescence and oxidation) and by poor DNA repair and transcription in general. (
  • Only 17.5 Gy induced lung fibrosis, senescence, and marks of accelerated aging according to the original study. (
  • This picture indicates that SIPS proceeds in cells that are actively fighting stress which facilitates premature senescence while failing to completely activate the orderly program of RS. (
  • Identification and understanding the differences between RS and SIPS senescence is critical for the development of anti-aging strategies that do not induce tumorigenesis. (
  • Exhaustion of adult stem cell pools as a result of deranged metabolic signaling, premature senescence as a response to oncogenic insults to the somatic genome, and other causes contribute to tissue degeneration with age. (
  • Molecular changes associated with age include telomere dysfunction, oxidative stress and deranged mitochondrial metabolism, inflammation, and cellular senescence, as well as altered signaling of sirtuins, insulin/insulin-like growth factor-1 (IGF-1), and the mammalian target of rapamycin (mTOR) pathway [ 3 , 4 , 5 ]. (
  • Increasing apoptosis (a natural programmed cell death) or premature replicative senescence can lead to premature aging. (
  • Further, it supports the idea that cellular senescence can cause or contribute to some aging phenotypes and diseases. (
  • Survival and morbidity of extremely premature infants based on obstetric assessment of gestational age. (
  • To provide current clinical information for obstetric decision-making and perinatal management, we present early morbidity and mortality data for extremely premature infants based on obstetric assessment of gestational age. (
  • We reviewed the records of 141 live-born infants with birth weights of 1600 g or lower born at a university hospital level III neonatal intensive care unit between January 1986 and April 1988, whose gestational ages estimated by antenatal obstetric evaluation were between 24-29 completed weeks. (
  • Rationale: Benefits of identifying risk factors for bronchopulmonary dysplasia in extremely premature infants include providing prognostic information, identifying infants likely to benefit from preventive strategies, and stratifying infants for clinical trial enrollment. (
  • To compare the neurologic and cognitive outcomes of 129 premature small for gestational age (SGA) infants with 300 premature appropriate for gestational age (AGA) infants through 6 years of age. (
  • Infants born at less than or equal to 37 weeks gestational age and less than or equal to 2500 g with birth weight 2 standard deviations or more below the mean birth weight for gestational age were categorized as SGA. (
  • Cognitive and neurologic outcomes of SGA and AGA prematures at 1, 2, 3, and 5 and/or 6 years of age were compared when the infants were stratified by gestational age in 2-week intervals or by birth weight in 500-g intervals. (
  • SGA infants had significantly poorer cognitive scores at each age when compared with AGA infants of similar gestational ages. (
  • Normal neurologic status was more likely at all assessments for the AGA than for SGA infants of comparable gestational age. (
  • Irrespective of degree of prematurity, SGA infants are at greater risk for neurodevelopmental impairment than are equally premature AGA infants. (
  • Ophthalmologists and parents need to be aware of the possibility of visual dysfunction already very early in life even in relatively older premature infants. (
  • Full term infants are usually hypermetropic, 1- 3 whereas premature babies, with or without previous retinopathy of prematurity (ROP), more often have myopia and astigmatism. (
  • 15- 25 The underlying mechanisms of myopia in premature infants are not well understood, and factors that may have a role, alone or in combination, include an increase in corneal curvature power, 26, 27 axial elongation, 28- 30 or decrease in anterior chamber depth, and higher refractive power of the lens. (
  • In addition, we evaluated the possible relation of birth weight (BW) and gestational age (GA) in premature infants with their refraction and keratometry findings. (
  • In both appropriate-for-gestational-age and small-for-gestational-age children, catch-up growth appears to be a statistical illusion created by charting growth of premature infants using chronological age rather than the more appropriate corrected age. (
  • Premature infants are at risk of developmental delay, and the actual developmental level corresponds to the degree of prematurity. (
  • Developmental delay in premature infants might be manifested as minor or major neurosensory deficit and impairment of intellectual or motor functions [6-8]. (
  • Early intervention in low-birth-weight premature infants. (
  • OBJECTIVE To evaluate the persistence of effects on health and development at age 5 years of the Infant Health and Development Program, an early childhood intervention that was provided to low-birth-weight (LBW) premature infants from neonatal discharge through age 3 years. (
  • If shortened or degraded, these end caps-called telomeres-make it harder for cells to regenerate, essentially making the body age faster while raising the risk for disease and early death. (
  • They took blood samples from more than 5,000 women aged 42 to 69 and measured the length of tiny pieces of DNA called telomeres. (
  • Although mouse models have provided insight into the role of telomeres in premature aging, they do not recapitulate all human symptoms. (
  • It is thought that aging occurs when the telomeres become too short for DNA replication and cell division to proceed normally. (
  • In addition, short telomeres have been linked to tissue damage, insulin resistance, and inflammation, as well as diseases generally thought to be affected by aging, such as diabetes and heart disease. (
  • You may notice that only four of the Progerias show accelerated telomere shortening, but since 10 of 11 involve DNA maintenance problems, I believe a Telomere theory of aging still applies insofar as telomeres are made of DNA and therefore a subset of DNA maintenance. (
  • Studies on normal aging have identified a molecular circuit in which the dysfunction of telomeres caused by cellular aging activates the TP53 gene. (
  • open source) showing that telomeres, sequences of DNA on the end of chromosomes taken as a marker of biological aging, are, on average, 356 base pairs shorter in study participants who slept for fewer than five hours per night than in those who slept for seven hours. (
  • It is notable, then, that the reduced longevity and fitness of mTR-/- mice were not manifest until the mouse telomeres had substantially shortened to lengths more typical of those found in aged human tissues. (
  • Metabolic dysfunction consistent with premature aging results from deletion of Pim kinases. (
  • From a clinical perspective, most DM symptoms are interpreted as a result of an accelerated aging (cataracts, muscular weakness and atrophy, cognitive decline, metabolic dysfunction, etc.), including an increased risk of developing tumors. (
  • From this point of view, DM1 could be described as a progeroid syndrome since a notable age-dependent dysfunction of all systems occurs. (
  • Satellite cell dysfunction seems to be a common feature of both age-dependent muscle degeneration (sarcopenia) and muscle wasting in DM and other muscle degenerative diseases. (
  • Dr. Kelesidis and his team will use the grant to investigate whether a novel mitochondrial antioxidant (MitoQ), and another potent antioxidant (4F) can help to stop the progression of T-Cell dysfunction associated with aging. (
  • With financial support from the Campbell Foundation, we will explore whether novel antioxidants improve dysfunction of immune cells that contribute to overall HIV-related aging" said Dr. Kelesidis. (
  • As an analogy of the mechanism in natural aging, we described a hypothetical mechanism of premature aging in WS: telomere dysfunction induced by WRN mutation causes multiple premature aging phenotypes of WS, including shortened cellular lifespan and inflammation induced by ROS, such as diabetes mellitus. (
  • This perspective review focused on a hypothetical cascade beginning with telomere dysfunction caused by WRN gene mutation leading to multi-phenotypes of premature aging and an abnormal profile of tumors. (
  • The study presents a new view on how mitochondrial dysfunction may contribute to aging by affecting cellular nucleotide pools and compromising nuclear genome maintenance and ultimately argues that the contribution of mitochondrial DNA mutations to aging remains to be defined. (
  • The mtDNA mutator mice have high levels of point mutations and linear deletions of mtDNA causing a progressive respiratory chain dysfunction and a premature aging phenotype. (
  • Hutchinson-Gilford progeria syndrome (HGPS) is a fatal disease characterized by premature aging in which young children fail to thrive and adolescents die from myocardial infarction or stroke. (
  • In Hutchinson-Gilford progeria, children as young as 1 to 2 start developing a host of dramatic symptoms, and they die at an average age of 14. (
  • Sam Berns, 15, who has the very rare premature-aging disease progeria, plays the drums in his high school's marching band. (
