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)

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. ....

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 ...
It is recognized that the immune system, comprising both innate (nonspecific) and acquired (specific) components, is an intricate defence system that is highly conserved across vertebrate species, and has, from an evolutionary perspective, undergone strong pressures to maximize survival to allow procreation. The significant improvements in human survival and lifespan to well beyond childbearing ages have been totally "unpredicted" by evolution. As a consequence, human immune systems are exposed to considerable additional antigenic exposure outside the forces of natural selection. It is in this situation that immunity begins to exert negative effects on human ageing (antagonistic pleiotropy), leading to gradual systemic failures. Research into age-related changes of the immune system is gathering pace as its importance within the context of multiple pathologies in ageing populations is realized. As part of this advance, [researchers] described the phenomenon of "inflammaging" at the turn 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 ...

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.
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 ...

Hutchinson-Gilford progeria syndrome (HGPS) is an extremely rare genetic disorder wherein symptoms resembling aspects of aging are manifested at a very early age. It is a genetic condition that occurs due to a de novo mutation in the LMNA gene encoding for the nuclear structural protein lamin A. The lamin family of proteins are thought to be involved in nuclear stability, chromatin structure and gene expression and this leads to heavy effects on the regulation and functionality of the cell machinery. The functional role of the large-conductance calcium-activated potassium channels (BKCa) is still unclear, but has been recently described a strong relationship with their membrane expression, progerin nuclear levels and the ageing process. In this study, we found that: i) the outward potassium membrane current amplitude and the fluorescence intensity of the BKCa channel probe showed higher values in human dermal fibroblast obtained from patients affected by HGPS if

Progeria ( /proʊˈdʒɪəriə/)[1], also called Hutchinson-Gilford progeria syndrome[2][3] and HGPS progeria syndrome[3] is a very rare genetic disorder. Children born with progeria show symptoms which are like aging.[4] This can include skin wrinkles and grey hair or baldness.[1] Progeria is one of several progeroid syndromes.[5] The word progeria comes from the Greek words "pro" (πρό), meaning "before" or "premature", and "gēras" (γῆρας), meaning "old age".[6] It is very rare, only 1 child in every 8 million live births.[7] People with progeria usually only live to their mid teens to early twenties.[8][9] It is a genetic condition that occurs as a new mutation. It is rarely inherited, as people with the condition do not usually live long enough to have children. Scientists are studying progeria because it might reveal clues about the normal process of aging.[10][11][12] Progeria was first described in 1886 by Jonathan Hutchinson.[13] It was also described independently in 1897 by ...

Semwal, Yogesh Murti Institute of Pharmaceutical Research, GLA University, Mathura-281406, Uttar Pradesh, India ABSTRACT Hutchinson-Gilford Progeria Syndrome (HGPS) is an extremely rare genetic disorder characterized by premature aging, involving aberrant splicing of the LMNA gene, resulting in the production of a disease-causing mutant lamin A protein called progerin. Clinical manifestations are evident by the first or second year of life and include the physical characteristics usually associated with the elderly. Because neither parent carries or expresses the mutation, each case is believed to represent a sporadic, new mutation that happens most notably in a single sperm or egg immediately prior to conception. ...
