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,

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 ...

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

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 ...

PRG Science & Technology Co., Ltd. (PRG S&T) is developing Progerinin (SLC-D011) for the treatment of the rare aging diseases Hutchinson-Gilford Progeria Syndrome (HGPS) and Werner Syndrome (WS).. Progerin, an abnormal splice variant of the inner nuclear membrane protein lamin A is implicated in the pathology of HGPS and WS. It is believed that the extremely strong binding between lamin A and progerin is responsible for the nuclear abnormality phenotype observed in HGPS. WS is caused by functional defect of WRN, RecQ4L DNA helicase and rapid accumulation of progerin in WRN deficient condition is thought to be the cause of premature aging in WS. PRG S&T has shown that Progerinin binds specifically to progerin reduces its expression in both HGPS and WS cells, Progerinin further prevents progerin-lamin A in HGPS cells. In a progeria mouse model (LmnaG609G/G609G), treatment with Progerinin via intraperitoneal (i.p) injection (20 mg/kg, twice per week) could increase the body weight and extend the ...

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. ...

The aging process can be accelerated by numerous cellular and molecular variables. Progeroid syndromes are one such example. The phenotypes of Hutchinson-Gilford Progeria Syndrome (HGPS) and Restrictive Dermopathy (RD) are both caused by an irregular pathway of the processing of prelamin A to mature lamin A, an integral component of the nuclear lamina. In wild-type cells, prelamin A undergoes farnesylation followed by cleavage that is carried out by the enzyme Zmpste24. A 50 amino acid deletion in the LMNA gene found in HGPS patients eliminates the cleavage site in prelamin A, causing an accumulation of farnesylated prelamin A. The buildup of this protein, known as progerin/LA∆50, occurs at the nuclear rim. In RD, nonfarnesylated and farnesylated prelamin A build up due to a deficiency in the Zmpste24 cleaving enzyme. In both syndromes, however, the accumulation of the different forms of prelamin A causes nuclear shape abnormalities and leads to phenotypes resembling premature aging. Currently, there

Hutchinson-Gilford progeria syndrome (HGPS) is a genetic disorder displaying features reminiscent of premature senescence caused by germline mutations in the LMNA gene encoding lamin A and C, essential components of the nuclear lamina. By studying a family with homozygous LMNA mutation (K542N), we showed that HGPS can also be caused by mutations affecting both isoforms, lamin A and C. Here, we aimed to elucidate the molecular mechanisms underlying the pathogenesis in both, lamin A- (sporadic) and lamin A and C-related (hereditary) HGPS. For this, we performed detailed molecular studies on primary fibroblasts of hetero- and homozygous LMNA K542N mutation carriers, accompanied with clinical examinations related to the molecular findings. By assessing global gene expression we found substantial overlap in altered transcription profiles (13.7%; 90/657) in sporadic and hereditary HGPS, with 83.3% (75/90) concordant and 16.7% (15/90) discordant transcriptional changes. Among the concordant ones we ...

Hutchinson-Gilford progeria syndrome (HGPS) is caused by a point mutation in the LMNA gene that activates a cryptic donor splice site and yields a truncated form of prelamin A called progerin. Small amounts of progerin are also produced during normal aging. Studies with mouse models of HGPS have allowed the recent development of the first therapeutic approaches for this disease. However, none of these earlier works have addressed the aberrant and pathogenic LMNA splicing observed in HGPS patients because of the lack of an appropriate mouse model. Here, we report a genetically modified mouse strain that carries the HGPS mutation. These mice accumulate progerin, present histological and transcriptional alterations characteristic of progeroid models, and phenocopy the main clinical manifestations of human HGPS, including shortened life span and bone and cardiovascular aberrations. Using this animal model, we have developed an antisense morpholino-based therapy that prevents the pathogenic Lmna ...

The segmental premature aging disease Hutchinson-Gilford Progeria (HGPS) is caused by a truncated and farnesylated form of Lamin A. In a mouse model for HGPS, a similar Lamin A variant causes the proliferative arrest and death of postnatal, but not embryonic, fibroblasts. Arrest is due to an inability to produce a functional extracellular matrix (ECM), because growth on normal ECM rescues proliferation. The defects are associated with inhibition of canonical Wnt signaling, due to reduced nuclear localization and transcriptional activity of Lef1, but not Tcf4, in both mouse and human progeric cells. Defective Wnt signaling, affecting ECM synthesis, may be critical to the etiology of HGPS because mice exhibit skeletal defects and apoptosis in major blood vessels proximal to the heart. These results establish a functional link between the nuclear envelope/lamina and the cell surface/ECM and may provide insights into the role of Wnt signaling and the ECM in aging ...

As noted earlier, some progeroid syndromes in humans are caused by missense mutations in lamin A, for example R644C and E578V (8). R644C and E578V fibroblasts did not have an accumulation of prelamin A (data not shown) but nevertheless contained misshapen nuclei, presumably because of the structurally and functionally abnormal lamin A. We predicted that a FTI might be effective in improving nuclear shape in the R644C and E578V fibroblasts because the FTI would prevent the biogenesis of mature lamin A and because the nonfarnesylated prelamin A would be located largely in the nucleoplasm. Indeed, the frequency of misshapen nuclei in R644C fibroblasts was reduced with a FTI (P = 0.0003 and P = 0.002 in two independent experiments) (Fig. 6D ). Similarly, the frequency of misshapen nuclei in E578V fibroblasts was reduced by the FTI treatment (P , 0.0001 in two independent experiments) (Fig. 6D ).. The missense mutations that we examined, R644C and E578V, are located in the carboxyl terminus of lamin ...

Alterations of nuclear architecture affect nuclear function. In particular, mutations in the LMNA gene encoding the nuclear proteins A-type lamins lead to a variety of changes of nuclear structure and chromatin modifications. Over 300 mutations in the LMNA gene have been associated with degenerative disorders, broadly termed laminopathies. These include muscular dystrophies, neuropathies, lypodystrophies, and premature aging syndromes. Hutchinson Gilford Progeria Syndrome is the most devastating lamin-related disease, with kids exhibiting phenotypes of premature aging and dying at adolescence from severe cardiovascular complications. Despite recent advances in the identification of pathways altered in HGPS, a clear cause or efficient therapy has not been found yet. One or our projects aims to determine whether genomic instability contributes to the pathophysiology of premature aging laminopathies, and characterize the molecular mechanisms involved. Our goal is to find therapeutic strategies that ...

Alteration in the immune system is one of the most profound aspects of aging. Progressive changes in the number of B lymphocyte progenitors during aging have been reported but the underlying mechanisms are still elusive. A heterozygous G608G mutation in the LMNA gene leads to a deletion of 50 amino acids in lamin A protein, termed progerin, and is the predominant cause of Hutchinson-Gilford progeria syndrome (HGPS). Lack of Zmpste24, a metalloproteinase responsible for prelamin A processing, leads to progeroid features resembling HGPS. Therefore Zmpste24-deficient mice provide an ideal mouse model to study the impact of lamin A and (premature) aging on the aging-related decline of B lymphopoiesis. Analysis of bone marrow (BM) nucleated cells revealed a decline of early B cell progenitors in Zmpste24−/− mice. BM transplantation in a congenic strain completely rescued the defects in B lymphopoiesis, indicating that the decline in B cell progenitors in Zmpste24−/− mice is attributable to defective

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. ...

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 ...

Hutchinson‐Gilford progeria syndrome (HGPS, or just plain progeria) is perhaps the best known of the rare but striking accelerated aging conditions caused by genetic mutation. These are not in fact accelerated aging, despite the apparent outcome, but rather DNA repair deficiencies. The water is always muddy when talking about damage and aging, however. Aging is just an accumulation of damage, and progeria is perhaps best thought of as an ordinarily fairly unimportant aspect of aging run amok to create a great deal of damage and dysfunction in cells and tissues.. Over the past decade or so researchers have come to a good understanding of the cause and mechanisms of progeria. An otherwise minor mutation in the LMNA gene leads to the generation of broken forms of a vital cellular structural protein, lamin A, and things go downhill from there: a progeria patients cells are greatly malformed and perform poorly at the most crucial of their tasks. Interestingly, dysfunctional forms of this protein ...

Lamins are type V intermediate filaments and represent the major constituent of the nuclear lamina. Mutations in the laminA/C gene as well as in other nuclear envelope associated proteins lead to a series of human genetic disorders, so-called laminopathies. The most prominent laminopathy is the Hutchinson-Gilford progeria syndrome (HGPS). HGPS patients appear prematurely aged developing aging-related conditions such as osteoporosis, loss of subcutaneous fat and cardiovaskular disease already during childhood. Many of the HGPS patients contain a single point mutation in the lamin A/C gene wh ...

Hutchinson-Gilford progeria syndrome is an extremely rare developmental autosomal dominant condition, characterized by premature and accelerated aging (~7 times the normal rate)[65] beginning at childhood. It affects 1 in ~4 million newborns; over 130 cases have been reported in the literature since the first described case in 1886.[66] The mean age of diagnosis is ~3 years and the mean age of death is ~13 years. The cause of death is usually myocardial infarction, caused by the severe hardening of the arteries (arteriosclerosis).[67] There is currently no treatment available.[68]. Individuals with HGPS typically appear normal at birth, but their growth is severely retarded, resulting in short stature, a very low body weight and delayed tooth eruption. Their facial/cranial proportions and facial features are abnormal, characterized by larger-than-normal eyes, a thin, beaked nose, thin lips, small chin and jaw (micrognathia), protruding ears, scalp hair, eyebrows, and lashes, hair loss, large ...

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 ...

Scientists have discovered a drug they believe can reverse the effects of premature aging and could extend human life by over a decade. Rapamycin was created from a chemical found in the soil on Easter Island, which is one of the most remote places on Earth and 2,000 miles off the coast of Chile. The drug, which has been nicknamed the forever young drug, was used in experiments on children suffering from Hutchinson-Gilford Progeria Syndrome (HGPS). HGPS is a rare condition in which aging is hyper-accelerate and sufferers die of old age at around 12 years. HGPS causes a protein called progerin to build up in every cell of the body, causing them to age prematurely. Rapamycin cleaned the cells of progerin, which swept away the defects and left healthy cells. Researchers are expected to start looking at whether the drug could be used more widely, after similarities between HGPS and the normal aging process were uncovered. The drug is already used to suppress the immune system in organ ...

Researchers at the Centro Nacional de Investigaciones Cardiovasculares (CNIC) and the Universidad de Oviedo have discovered a new molecular mechanism involved in the premature development of atherosclerosis in mice with Hutchinson-Gilford progeria syndrome (HGPS). Moreover, the results, published in EMBO Molecular Medicine, identify a potential therapeutic target for this severe genetic disease, which is characterized by the premature onset of cardiovascular disease and early death, usually from a heart attack or stroke, between the ages of 6 and 20 years.. Progeria is very rare genetic disease caused by a mutation in the LMNA gene. The disease affects an estimated 400 people worldwide. HGPS patients show accelerated aging linked to a high risk of cardiovascular disease. In the words of study leader Vicente Andrés, studying this disease brings us closer to a possible treatment for disease victims and can provide important information about normal physiological aging and the factors that ...

The nuclear lamina is an intermediate filament network that underlies the inner nuclear membrane and ensures that the nuclear functions are able to undergo normal processes. The transport between the cytoplasm and the nucleus, the role of maintaining chromatin, and therefore the epigenetic profile of the cell are also regulated by the nuclear lamina as well as DNA replication and DNA repair. Mutations in the gene that encodes the nuclear lamina protein, lamin A, cause more than 18 tissue-specific diseases including Hutchinson-Gilford progeria syndrome (HGPS), which is manifested with tissue-specific mechanisms of ageing. Children affected by HGPS die of myocardial infarction or stroke by the time they are 16 years old and their vasculature is characterized by stiff calcified arteries and the loss of VSMCs. Since lamin A is made from a precursor protein, prelamin A, HGPS affected children have the mutation that deletes key amino acid sequences that are required for the final posttranslational ...

Hematopoietic stem cells (HSCs) residing in the bone marrow (BM) accumulate during aging but are functionally impaired. However, the role of HSC-intrinsic and -extrinsic aging mechanisms remains debated. Megakaryocytes promote quiescence of neighboring HSCs. Nonetheless, whether megakaryocyte-HSC interactions change during pathological/natural aging is unclear. Premature aging in Hutchinson-Gilford progeria syndrome recapitulates physiological aging features, but whether these arise from altered stem or niche cells is unknown. Here, we show that the BM microenvironment promotes myelopoiesis in premature/physiological aging. During physiological aging, HSC-supporting niches decrease near bone but expand further from bone. Increased BM noradrenergic innervation promotes β2-adrenergic-receptor(AR)-interleukin-6-dependent megakaryopoiesis. Reduced β3-AR-Nos1 activity correlates with decreased endosteal niches and megakaryocyte apposition to sinusoids. However, chronic treatment of progeroid mice with β3

A specific mutation in the LMNA gene has been found in most patients with Hutchinson-Gilford progeria syndrome, which is a condition that causes the dramatic, rapid appearance of aging beginning in childhood. This mutation changes a single DNA building block (nucleotide) in the gene. Specifically, the mutation replaces the nucleotide cytosine with the nucleotide thymine at position 1824 (written as C1824T). This mutation is also sometimes noted as Gly608Gly or G608G, which refers to the position in the lamin A protein affected by the mutation. Although the C1824T mutation is not predicted to change an amino acid, it alters the way the genes instructions are used to make a protein. The C1824T mutation leads to an abnormal version of the lamin A protein called progerin, which is missing 50 amino acids near one end. The location of this mutation does not affect the production of lamin C. Other mutations in the LMNA gene have been identified in a small number of people with the features of ...

The nuclear lamina consists of a two-dimensional matrix of proteins located next to the inner nuclear membrane. The lamin family of proteins make up the matrix and are highly conserved in evolution. During mitosis, the lamina matrix is reversibly disassembled as the lamin proteins are phosphorylated. Lamin proteins are thought to be involved in nuclear stability, chromatin structure and gene expression. Vertebrate lamins consist of two types, A and B. Alternative splicing results in multiple transcript variants. Mutations in this gene lead to several diseases: Emery-Dreifuss muscular dystrophy, familial partial lipodystrophy, limb girdle muscular dystrophy, dilated cardiomyopathy, Charcot-Marie-Tooth disease, and Hutchinson-Gilford progeria syndrome.

Five (26%) LMNA mutation carriers with an enlarged and dysfunctional left ventricle were older (67 ± 8 vs. 39 ± 14 years) and had a higher pro-B-type natriuretic peptide level (median 333 ng/l [25th to 75th percentiles: 62 to 1,943] vs. median 66 ng/l [25th to 75th percentiles: 29 to 107]) than LMNA mutation carriers with normal LV dimension and function (both p , 0.05). In all LMNA mutation carriers, PRA and catecholamine levels were within normal range, whereas the plasma aldosterone level was close to the upper normal limit (median 140 pg/ml [25th to 75th percentiles: 75 to 170], reference values: 20 to 180 pg/ml). Eight LMNA mutation carriers (42%) showed myocardial LGE with a patchy (n = 3) or mid wall (n = 5) pattern. In LMNA mutation carriers, LGE was more frequently detected in carriers with LV dysfunction (4 of 5 patients, 80%) compared with those with normal LV dimension and function (4 of 14 [29%], p , 0.05). Myocardial LGE was more common in carriers with first-degree ...

Could a component of red wine be helpful? Two studies published recently point to a possible role of resveratrol in progeria. While the biochemistry is complex, basically researchers found that resveratrol improves the binding of A-type lamins with a factor called SIRT1 (sirtuin1), and that resveratrol also can slow down loss of body weight, improve bone mineral density and structure, and significantly extend the lives of mice. The drug rapamycin (also known as sirolimus), an immunosuppressant typically given to organ transplant patients to prevent organ rejection, has demonstrated an ability to reduce levels of progerin in an in vitro study conducted by experts at the National Human Genome Research Institute. Experts observed that rapamycin enhanced the destruction of progerin in progeria cells as well as reduced the formation of certain progerin aggregates, among other benefits. These findings led the authors to note that rapamycin treatment could provide clinical benefit for children with ...

Laminopathies Meetings at the Kings College Bush House in London! The 9th UK Nuclear Envelope Meeting -3rd International Meeting on Laminopathies Joint Conference will take place in London on September 2-5 2019. A Satellite Meeting of the European Network for Laminopathies will take place on September 3-5.

LMNA-related disorders are caused by mutations in the LMNA gene, which encodes for the nuclear envelope proteins, lamin A and C, via alternative splicing. Laminopathies are associated with a wide range of disease phenotypes, including neuromuscular, cardiac, metabolic disorders and premature aging syndromes. The most frequent diseases associated with mutations in the LMNA gene are characterized by skeletal and cardiac muscle involvement. This review will focus on genetics and clinical features of laminopathies affecting primarily skeletal muscle. Although only symptomatic treatment is available for these patients, many achievements have been made in clarifying the pathogenesis and improving the management of these diseases.

The Bingley Bullet, Ian Hutchinson, took a sensational win on the Milwaukee Yamaha in the Macau Grand Prix in China yesterday to mark a fairytale return to road racing following serious injury. 34 year old Hutchinson overtook Michael Rutter (SMT Honda) on the fourth lap of the 3.8 mile Guia circuit and opened a two second gap that he maintained until the race was brought to a premature end on the 11th of 15 laps because of a crash involving Dean Harrison. Harrison was unhurt in the accident but his bike was lying in the track.

Governor Asa Hutchinson (R-AR) said Sunday on NBCs Meet the Press that President George W. Bushs comments comparing the January 6 Capitol protesters to the Islamic terrorists were words of wisdom.. During his speech at the 9/11 memorial service for Flight 93 in Pennsylvania, Bush said, There is little cultural overlap between violent extremists abroad and violent extremists at home. Then there is disdainful pluralism in their disdain for human life. In their determination to defile national symbols they are children of the same foul spirit and it is our continuing duty to confront them.. Anchor Chuck Todd said, Im curious what you thought of what former President Bush said during his speech in Shanksville, Pennsylvania. It touched a lot of people..

The conversion of mammalian prelamin A to mature lamin A proceeds through the removal of 18 amino acids from the carboxyl terminus. The initial step in this processing is the isoprenylation of a CAAX box cysteine. This proteolytic event is distinctive for prelamin A among the known prenylated mammalian proteins. Since the carboxyl terminus of prelamin A is removed during maturation, it is not obvious that this protein would undergo the two reactions subsequent to prenylation observed in other CAAX box proteins--the endoproteolytic removal of the carboxyl-terminal 3 amino acids and the subsequent methylation of the now carboxyl-terminal cysteine. To characterize the maturation of prelamin A further, we have developed a CHO-K1 cell line that possesses a dexamethasone-inducible human prelamin A against a genetic background of high mevalonate uptake. Utilizing this cell line in association with antibodies specific to the transgenic prelamin A, we have been able to demonstrate directly in vivo that ...

Joint inflammation causes meniscus degeneration and can exacerbate post-traumatic meniscus injuries by extracellular matrix degradation, cellular de-differentiation and cell death. The aim of this study was to examine whether anti-inflammatory interleukin-10 exerts protective effects in an in vitro model of TNF-α-induced meniscus degeneration. Meniscus tissue was harvested from the knees of adult cows. After 24 h of equilibrium explants were simultaneously treated with bovine TNF-α and IL-10. After an incubation time of 72 h cell death was measured histomorphometrically (nuclear blebbing, NB) and release of glycosaminoglycans (GAG, DMMB assay) and nitric oxide (NO, Griess-reagent) were analysed. Transcription levels (mRNA) of matrix degrading enzymes, collagen type X (COL10A1) and nitric oxide synthetase 2 (NOS2) were measured by quantitative real time PCR. TNF-α-dependent formation of the aggrecanase-specific aggrecan neoepitope NITEGE was visualised by immunostaining. Differences between groups

On summary judgment, the district court held that Mr. Hutchinson could not satisfy the requirements for standing under the Lanham Act set out by this court in Stanfield v. Osborne Industries, Inc., 52 F.3d 867 (10th Cir. 1995). On de novo review, see Wilson v. Glenwood Intermountain Properties, Inc., 98 F.3d 590, 593 (10th Cir. 1996), we reach the same conclusion. Further, we hold that the standing deficiencies implicate the limitations of Article III of the Constitution. Plaintiffs bear the burden of proving standing with the manner and degree of evidence required at the particular stage of the litigation. In response to a summary judgment motion, the nonmovant must present specific facts by affidavit or other evidence, which will be taken as true for purposes of the motion. Summary judgment is then proper if there is no genuine issue of material fact so that the moving party is entitled to judgment as a matter of law. Gilbert v.
