Strains of mice in which certain GENES of their GENOMES have been disrupted, or "knocked-out". To produce knockouts, using RECOMBINANT DNA technology, the normal DNA sequence of the gene being studied is altered to prevent synthesis of a normal gene product. Cloned cells in which this DNA alteration is successful are then injected into mouse EMBRYOS to produce chimeric mice. The chimeric mice are then bred to yield a strain in which all the cells of the mouse contain the disrupted gene. Knockout mice are used as EXPERIMENTAL ANIMAL MODELS for diseases (DISEASE MODELS, ANIMAL) and to clarify the functions of the genes.

The determination of the pattern of genes expressed at the level of GENETIC TRANSCRIPTION, under specific circumstances or in a specific cell.
The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

A federation of seven states on the southeast portion of the Arabian peninsula: Abu Dhabi, Ajman, Dubai, Fujairah, Ras al-Khaimah, Sharjah and Umm al-Qaiwain. In 1820 a treaty of peace was concluded between Great Britain and native rulers. During the 19th century the rulers agreed to suppression of the slave trade and restriction of foreign relations to Great Britain. The Trucial Council was established in 1952 and defense treaties with Great Britain terminated. In 1971 an independent six-member federation was formed, with Ras al-Khaimah joining the federation in 1972. (From Webster's New Geographical Dictionary, 1988, p1250)

p57(Kip2) is degraded through the proteasome in osteoblasts stimulated to proliferation by transforming growth factor beta1. (1/288)

Cyclin-dependent kinase inhibitory proteins are negative regulators of the cell cycle. Although all the cyclin-dependent kinase inhibitory proteins may be involved in cell cycle control during a differentiation process, only p57(Kip2) is shown to be essential for embryonic development. However, the role of p57 in the control of the cell cycle is poorly understood. Using osteoblasts derived from the calvaria of rat fetus, we show that p57 is accumulated in cells starved by low serum. Cyclin-dependent kinase 2 activity was suppressed in these cells with a significant amount bound to p57. Treatment of the cells with transforming growth factor beta1 dramatically reduced the amount of p57, resulting in an activation of cyclin-dependent kinase 2 activity and the stimulation of cell proliferation. The decrease in p57 was inhibited by treating the cells with proteasome inhibitors, Z-Leu-Leu-Leu-aldehyde or lactacystin, but not with Z-Leu-Leu-aldehyde, which is an inhibitor of calpain, indicating that p57 is degraded through the proteasome pathway. p57 was also shown to be ubiquitinated in vitro. Because transforming growth factor beta1 not only stimulates the growth but also inhibits the differentiation of the cells in this system, our results may suggest a possible involvement of p57 in the control of osteoblastic cell proliferation and differentiation.  (+info)

Analysis of germline CDKN1C (p57KIP2) mutations in familial and sporadic Beckwith-Wiedemann syndrome (BWS) provides a novel genotype-phenotype correlation. (2/288)

Beckwith-Wiedemann syndrome (BWS) is a human imprinting disorder with a variable phenotype. The major features are anterior abdominal wall defects including exomphalos (omphalocele), pre- and postnatal overgrowth, and macroglossia. Additional less frequent complications include specific developmental defects and a predisposition to embryonal tumours. BWS is genetically heterogeneous and epigenetic changes in the IGF2/H19 genes resulting in overexpression of IGF2 have been implicated in many cases. Recently germline mutations in the cyclin dependent kinase inhibitor gene CDKN1C (p57KIP2) have been reported in a variable minority of BWS patients. We have investigated a large series of familial and sporadic BWS patients for evidence of CDKN1C mutations by direct gene sequencing. A total of 70 patients with classical BWS were investigated; 54 were sporadic with no evidence of UPD and 16 were familial from seven kindreds. Novel germline CDKN1C mutations were identified in five probands, 3/7 (43%) familial cases and 2/54 (4%) sporadic cases. There was no association between germline CDKN1C mutations and IGF2 or H19 epigenotype abnormalities. The clinical phenotype of 13 BWS patients with germline CDKN1C mutations was compared to that of BWS patients with other defined types of molecular pathology. This showed a significantly higher frequency of exomphalos in the CDKN1C mutation cases (11/13) than in patients with an imprinting centre defect (associated with biallelic IGF2 expression and H19 silencing) (0/5, p<0.005) or patients with uniparental disomy (0/9, p<0.005). However, there was no association between germline CDKN1C mutations and risk of embryonal tumours. No CDKN1C mutations were identified in six non-BWS patients with overgrowth and Wilms tumour. These findings (1) show that germline CDKN1C mutations are a frequent cause of familial but not sporadic BWS, (2) suggest that CDKN1C mutations probably cause BWS independently of changes in IGF2/H19 imprinting, (3) provide evidence that aspects of the BWS phenotype may be correlated with the involvement of specific imprinted genes, and (4) link genotype-phenotype relationships in BWS and the results of murine experimental models of BWS.  (+info)

CDKN1C expression in Beckwith-Wiedemann syndrome patients with allele imbalance. (3/288)

In this study, we have examined CDKN1C expression in BWS patients with allele imbalance (AI) affecting the 11p15 region. Two of two informative patients with AI, attributable to mosaic paternal isodisomy, exhibited reduced levels of CDKN1C expression in the liver and kidney, respectively, relative to expression levels in the equivalent tissues in normal controls. Although overall expression was reduced, some expression from the paternally derived CDKN1C allele was evident, consistent with incomplete paternal imprinting of the gene. One patient showed evidence of maternal allele silencing in addition to AI. These findings show for the first time that CDKN1C expression is reduced in BWS patients with AI and suggest that CDKN1C haploinsufficiency contributes to the BWS phenotype in patients with mosaic paternal isodisomies of chromosome 11.  (+info)

TGF-beta1-mediated hypertrophy involves inhibiting pRB phosphorylation by blocking activation of cyclin E kinase. (4/288)

When renal epithelial cells are exposed to epidermal growth factor-transforming growth factor-beta1 (EGF-TGF-beta1) the typical EGF-mediated hyperplastic growth response is converted to a hypertrophic growth response. Hypertrophy in this setting involves cell entrance into G(1), but arrest of cell cycle progression at the G(1)/S interface. Late G(1) arrest is mediated by retaining retinoblastoma protein (pRB) in its active, hypophosphorylated state. The present studies examine the mechanism by which pRB is retained in its active state. The results demonstrate that TGF-beta1-mediated conversion of hyperplasia to hypertrophy involves preventing activation of cdk2/cyclin E kinase but has no effect on cdk4(6)/cyclin D kinase activity. Preventing activation of cyclin E kinase is associated with 1) decreased abundance of cdk2/cyclin E complexes and 2) retention of p57(Kip2) in formed cdk2/cyclin E complexes. The development of hypertrophy does not involve regulation of either cdk2, cyclin E, or cdc25A protein abundances, or the abundance of p27(Kip1) or p21 in formed complexes.  (+info)

Spatial and temporal expression of p57(KIP2) during murine lens development. (5/288)

The expression patterns of p57(KIP2), an important cyclin-dependent kinase inhibitor in the lens, is investigated. This study shows that the expression of p57 mRNA throughout lens morphogenesis and growth correlates with lens cell withdrawal from the cell cycle (shown by changing patterns of BrdU incorporation) and the onset of lens fibre differentiation (shown by beta-crystallin expression). p57 expression at the early stages of fibre differentiation make it a useful marker for the initiation of this process.  (+info)

p57KIP2 expression and loss of heterozygosity during immortal conversion of cultured human mammary epithelial cells. (6/288)

We have uncovered a novel role for the cyclin-dependent kinase inhibitor, p57KIP2, during the immortalization of cultured human mammary epithelial cells (HMECs). HMECs immortalized after chemical carcinogen exposure initially expressed little or no telomerase activity, and their telomeres continued to shorten with passage. Cell populations whose mean terminal restriction fragment (TRF) length declined to < or = 3 kb exhibited slow heterogeneous growth and contained many nonproliferative cells. These conditionally immortal HMEC cultures accumulated large quantities of p57 protein. With continued passage, the conditionally immortal cell populations very gradually converted to a fully immortal phenotype of good uniform growth, expression of high levels of telomerase activity, and stabilization of telomere length. The fully immortal HMECs that grew well did not accumulate p57 in G0 or during the cell cycle. DNA and RNA analysis of mass populations and individual subclones of conditionally immortal HMEC line 184A1 showed that continued growth of conditionally immortal cells with critically short telomeres was repeatedly accompanied by loss of the expressed p57 allele and transient expression of the allele imprinted previously. Conditionally immortal 184A1 with mean TRF > 3 kb, infected with retroviruses containing the p57 gene, exhibited premature slow heterogeneous growth. Conversely, exogenous expression of human telomerase reverse transcriptase (hTERT), the catalytic subunit of telomerase, in 184A1 with mean TRF > 3 kb prevented both the slow heterogeneous growth phase and accumulation of p57 in cycling populations. These data indicate that in HMECs that have overcome replicative senescence, p57 may provide an additional barrier against indefinite proliferation. Overcoming p57-mediated growth inhibition in these cells may be crucial for acquisition of the unlimited growth potential thought to be critical for malignant progression.  (+info)

A human p57(KIP2) transgene is not activated by passage through the maternal mouse germline. (7/288)

Genomic imprinting results in expression of some autosomal genes from one parental allele only. Human chromosome 11p15, and the syntenic region on mouse distal chromosome 7, contain several imprinted genes, including p57 (KIP2) ( CDKN1C ) and IGF2. These two genes, which are separated by >700 kb, are both implicated in the pathogenesis of Beckwith-Wiedemann syndrome. We have shown previously that an Igf2/H19 transgene is expressed appropriately and can imprint at ectopic chromosomal locations. To investigate the p57 (KIP2) region, we similarly tested the imprinting and function of a 38 kb human genomic fragment containing the p57 (KIP2) gene in transgenic mice. This transgene showed appropriate tissue-specific expression and transgene copy number-dependent expression at ectopic sites. However, the levels of expression are reminiscent of that found for the paternal allele in humans (10%). There was no change in expression levels when the transgene was inherited from the maternal germline. These results suggest that the cis -elements required for enhanced expression of the maternally inherited p57 (KIP2) allele lie at a distance from the gene. This finding has important implications for the role of this gene in the human disease, in particular with respect to the translocation breakpoints identified in some patients.  (+info)

Mechanism for inactivation of the KIP family cyclin-dependent kinase inhibitor genes in gastric cancer cells. (8/288)

The mechanism for inactivation of the KIP family cyclin-dependent kinase inhibitor (CDKI) genes, the p21, p27, and p57 genes, in gastric cancer cells was tested by treating the cells with either the DNA demethylation agent, 5-aza-2'-deoxycytidine or the histone deacetylase inhibitor, n-butyric acid or trichostatin A. RNA expression of the gene was determined by reverse transcription PCR. The p21 gene was activated only by histone deacetylase inhibitor. The p57 gene was activated by histone deacetylase inhibitors in all of the gastric cancer cell lines and by 5-aza-2'-deoxycytidine in five of eight gastric cell lines. However, the p27 gene was not inactivated in gastric cancer cell lines. The methylation status of the promoter of the p21 and p57 genes was also tested by digestion with the methylation-sensitive restriction enzymes and a subsequent PCR. The promoter of the p21 gene has no methylation. The promoter of the p57 gene is, however, methylated in five of eight gastric cancer cell lines as expected from the result of the treatment with 5-aza-2'-deoxycytidine. Formation of the inactive chromatin through histone deacetylation seems to be the general mechanism for inactivation of both the p21 and the p57 genes in gastric cancer cells. Hypermethylation of promoter region seems to be an alternative pathway for inactivation of the p57 gene.  (+info)

Beckwith-Wiedemann syndrome (BWS) is a well-studied human overgrowth disorder, associated with visceromegaly, exomphalos, and predisposition to Wilms tumor and other pediatric cancers. BWS is a clinical syndrome, not a single disorder. Phenotypic heterogeneity is prominent, and we now appreciate that this reflects an underlying molecular heterogeneity. The syndrome can be caused by various molecular defects, which lead to altered expression of certain imprinted genes on chromosome 11p15. Multiple studies have revealed striking epigenotype-phenotype correlations, in which exomphalos tracks with one type of imprinting defect, affecting the CDKN1C gene, while Wilms tumor predisposition tracks with a different imprinting defect, affecting the IGF2 and H19 genes. Here we review the clinical and molecular features of BWS and summarize the data from these recent investigations. We also review the fascinating association of BWS with twinning, and discuss preliminary studies suggesting an increased ...

Currently, quantitative Southern analysis using DNA methylation-sensitive restriction enzymes is used in molecular diagnosis of this syndrome. METHODS: We describe a rapid and highly quantitative test for assessing DNA methylation at 11p15 using sodium bisulfite treatment of genomic DNA coupled with quantitative TaqMan methylation-sensitive polymerase chain reaction. RESULTS: TaqMan MSP can assess DNA methylation at both differentially methylated region (DMR)1 and DMR2 at 11p15. In addition, by using TaqMan MSP we were able to determine the parent of origin of a duplication of 11p15 by quantification of ...
Despite its potential role as a tumor suppressor, p27 gene, a member of the Cip/Kip family of cyclin-dependent kinase inhibitor genes, has never been found mutated in human tumors. We investigated p27 protein expression in a series of 108 non-small cell lung cancers (57.4% stage 1, 16.7% stage 2, and 25.9% stage 3) to determine whether the lack or altered expression of this protein correlates with neoplastic transformation and/or progression. We performed immunohistochemistry and Western blot analysis of each specimen. We found that tumors expressing low to undetectable levels of p27 contained high p27 degradation activity. When we evaluated the outcome of the patients in relationship to p27 expression, we found p27 to be a prognostic factor correlating with the overall survival times (P = 0.0012).. The possibility of a simple assay, such as the immunohistochemical analysis of p27 expression on routinely formalin-fixed, paraffin-embedded specimens, has considerable value for the prognosis of ...

Beckwith-Wiedemann syndromeDefinitionBeckwith-Wiedemann syndrome (BWS) refers to a disorder of overgrowth. This condition is usually characterized by large body size (macrosomia), large tongue (macroglossia), enlarged internal organs (visceromegaly), the presence of an abdominal wall defect (umbilical hernia or omphalocele ), and low blood sugar in the newborn period (neonatal hypoglycemia). Source for information on Beckwith-Wiedemann Syndrome: Gale Encyclopedia of Genetic Disorders dictionary.
Cyclin-Dependent Kinase Inhibitor p27: A cyclin-dependent kinase inhibitor that coordinates the activation of CYCLIN and CYCLIN-DEPENDENT KINASES during the CELL CYCLE. It interacts with active CYCLIN D complexed to CYCLIN-DEPENDENT KINASE 4 in proliferating cells, while in arrested cells it binds and inhibits CYCLIN E complexed to CYCLIN-DEPENDENT KINASE 2.

The Beckwith-Wiedemann syndrome, originally described by Beckwith in 1963 and Wiedemann in 1964, included congenital anomalies such as macroglossia, exomphalos, postnatal somatic gigantism, severe hypoglycemia, abdominal wall defect, capillary nevus flameus and hemihypertrophy. Macroglossia is the most common manifestation of Beckwith-Wiedemann syndrome, with studies reporting between 82 and 95 percent of the cases. Macroglossia may cause the upper airway obstruction, deglutition difficulty, articulation interference and protrusion of dentoalveloar structures resulting in anterior open bite and a mandibular prognathism. We experienced a 5 month-old male with upper airway obstruction, deglutition difficulty and recurrent upper airway infection due to macroglossia associated with Beckwith-Wiedemann syndrome and significant improvement in respiration, feeding and oral competence at 14 months follow-up after rhomboid resection and primary closure of tongue. ...
We report on an 8-month-old girl with a novel unbalanced chromosomal rearrangement, consisting of a terminal deletion of 4p and a paternal duplication of terminal 11p. Each of these is associated with the well-known clinical phenotypes of Wolf-Hirschhorn syndrome (WHS) and Beckwith-Wiedemann syndrome (BWS), respectively. She presented for clinical evaluation of dysmorphic facial features, developmental delay, atrial septal defect (ASD), and left hydro-nephrosis. High-resolution cytogenetic analysis revealed a normal female karyotype, but subtelomeric fluorescence in situ hybridization (FISH) analysis revealed a der(4)t(4;11) (pter;pter). Both FISH and microarray CGH studies clearly demonstrated that the WHS critical regions 1 and 2 were deleted, and that the BWS imprinted domains (ID) 1 and 2 were duplicated on the der(4). Parental chromosome analysis revealed that the father carried a cryptic balanced t(4;11)(pter;pter). As expected, our patient manifests findings of both WHS (a growth ...
The combination of intrauterine growth restriction, metaphyseal dysplasia, adrenal hypoplasia congenita, and genital anomalies is commonly known by the acronym IMAGe. This rare syndrome has signs and symptoms that affect many parts of the body.. Most affected individuals grow slowly before birth (intrauterine growth restriction) and are small in infancy. They have skeletal abnormalities that often become apparent in early childhood, although these abnormalities are usually mild and can be difficult to recognize on x-rays. The most common bone changes are metaphyseal dysplasia and epiphyseal dysplasia; these are malformations of the ends of long bones in the arms and legs. Some affected individuals also have an abnormal side-to-side curvature of the spine (scoliosis) or thinning of the bones (osteoporosis).. Adrenal hypoplasia congenita is the most severe feature of IMAGe syndrome. The adrenal glands are a pair of small glands on top of each kidney. They produce a variety of hormones that ...
The cortactin oncoprotein is frequently overexpressed in head and neck squamous cell carcinoma (HNSCC), often due to amplification of the encoding gene (CTTN). While cortactin overexpression enhances invasive potential, recent research indicates that it also promotes cell proliferation, but how cortactin regulates the cell cycle machinery is unclear. In this article we report that stable short hairpin RNA-mediated cortactin knockdown in the 11q13-amplified cell line FaDu led to increased expression of the Cip/Kip cyclin-dependent kinase inhibitors (CDKIs) p21(WAF1/Cip1), p27(Kip1), and p57(Kip2) and inhibition of S-phase entry. These effects were associated with increased binding of p21(WAF1/Cip1) and p27(Kip1) to cyclin D1- and E1-containing complexes and decreased retinoblastoma protein phosphorylation. Cortactin regulated expression of p21(WAF1/Cip1) and p27(Kip1) at the transcriptional and posttranscriptional levels, respectively. The direct roles of p21(WAF1/Cip1), p27(Kip1), and p57(Kip2) ...
The major findings in this study are that the Kip/Cip and Ink CKIs differentially regulate cdk2 and cdk4 in VSMCs; this, in turn, leads to differences in the inhibition of VSMC proliferation in vitro and in vivo. The expression of p27Kip1 and p21Cip1 in VSMCs inactivated cdk2 and cdk4, whereas p16Ink4 inhibited only cdk4 activity. In vivo, p27Kip1 significantly inhibited intimal cell proliferation and the development of a neointima after vascular injury, whereas p16Ink4 expression did not lead to a reduction in cell proliferation or neointima formation.. This different pattern of CKI inactivation of the CDKs suggests varied biological roles for p27Kip1 and p21Cip1 compared with p16Ink4 in VSMCs. p27Kip1 was initially characterized as an inhibitor of cyclin E/cdk2 phosphorylation.10 11 p27Kip1 and p21Cip1 are upregulated in several animal models of wound repair. p27Kip1 is constitutively expressed in normal arteries, is downregulated after arterial injury, and is upregulated during the later ...
We identified two patients with chromosomal abnormalities including SHOX trisomy by karyotype, one 9q22.3 microdeletion syndrome by CMA, two cases of Beckwith-Wiedemann syndrome by targeted MS-MLPA analysis and nine cases with heterozygous pathogenic or likely pathogenic genetic variants by multigene analysis techniques (FBN1 = 3, NSD1 = 2, NFIX = 1, SUZ12 = 1, CHD8 = 1, MC4R = 1). Three of 20 patients analyzed by WES had their diagnosis established. Only one non-syndromic patient had a definitive diagnosis. The sequential genetic assessment diagnosed 14 out of 42 (33.3%) tall patients. ...
