The Rep proteins of adeno-associated virus type 2 (AAV) are known to bind to Rep recognition sequences (RRSs) in the AAV inverted terminal repeats (ITRs), the AAV p5 promoter, and the preferred AAV integration site in human chromosome 19, called AAVS1.

We used the 16-mer core sequences of the RRSs in the AAV ITRs and AAVS1 separately as query sequences and identified 18 new RRSs in or flanking the genes coding for the following: tyrosine kinase activator protein 1 (TKA-1); colony stimulating factor-1; insulin-like growth factor binding protein 2 (IGFBP-2); histone H2B.1; basement membrane heparan sulfate proteoglycan, also known as perlecan; the AF-9 gene product, which is involved in the chromosomal translocation t (9:11)(p22:q23); the betaB subunit of the hormone known as inhibin; interleukin-2 enhancer binding factor; an endoplasmic reticulum-Golgi intermediate compartment resident protein called p63; a global transcription activator (hSNF2L); the beta-actin repair domain; a retinoic acid-inducible factor, also known as midkine; a breast tumor autoantigen; a growth-arrest- and DNA-damage-inducible protein called gadd45; the cyclin-dependent kinase inhibitor called KIP2, which inhibits several G1 cyclin-cyclin-dependent kinase complexes; and the hereditary breast and ovarian cancer gene (BRCA1).

Studies of knockout mice have largely defined the essential roles of the insulin-like growth factors (IGF-I and IGF-II), insulin and their receptors in embryonic and fetal growth, and have provided compelling evidence that increased IGF-II gene expression and/or abundance can stimulate excessive fetal somatic growth.

TH also decreased expression of brain-derived neurotrophic factor, its receptor trkB, and the receptor for TRH.
|
18 |
11796486
|
These, in addition to two other genes, neuronatin and PB cadherin, which were up- and down-regulated, respectively, showed a more rapid response to TH than the cell cycle regulators and may represent direct targets of TH.

ZAC, LIT1 (KCNQ1OT1) and p57KIP2 (CDKN1C) are in an imprinted gene network that may play a role in Beckwith-Wiedemann syndrome.
|
59 |
15888726
|
ZAC is an imprinted gene expressed from the paternal allele of chromosome 6q24 within a region known to harbor a tumor suppressor gene for several types of neoplasia. p57(KIP2) (CDKN1C) is a maternally expressed gene located on chromosome 11p15.5 which encodes a cyclin-dependent kinase inhibitor that may also act as a tumor suppressor gene.
|
60 |
15888726

Expression and functional analysis of genes deregulated in mouse placental overgrowth models: Car2 and Ncam1.
|
79 |
16247769
|
Different causes, such as maternal diabetes, cloning by nuclear transfer, interspecific hybridization, and deletion of some genes such as Esx1, Ipl, or Cdkn1c, may underlie placental overgrowth.
|
80 |
16247769
|
In the present study, we focused on two genes, Car2 and Ncam1, which both exhibited increased expression in interspecies and cloned hyperplastic placentas.
|
81 |
16247769
|
Apart from a detailed expression analysis of both genes during normal murine placentation, we also assessed morphology of placentas that were null for Car2 or Ncam1.
|
82 |
16247769
|
Finally, we attempted to rescue placental hyperplasia in a congenic model of IHPD by decreasing transcript levels of Car2 or Ncam1.
|
83 |
16247769
|
Contrary to expectations, homozygous deletion of either Car2 or Ncam1 did not result in placental phenotypes.
|
84 |
16247769
|
However, expression analysis of Car3 and Ncam2, which can take over the function of Car2 and Ncam1, respectively, indicated a possible rescue mechanism, as Car3 and Ncam2 were expressed in spongiotrophoblast of Car2 and Ncam1 mutant placentas.
|
85 |
16247769
|
On the other hand, downregulation of either Car2 or Ncam1 did not rescue any of the placental phenotypes of AT24 placentas, a congenic model for interspecies hybrid placentas.
|
86 |
16247769
|
This strongly suggested that altered expression of Car2 and Ncam1 is a downstream event in placental hyperplasia.
|

Previously, the exact opposite epigenetic alteration (gain of DNA methylation) had been detected at the domain's 'imprinting control region' (ICR) in patients with Beckwith-Wiedemann Syndrome (BWS), a complex disorder of fetal overgrowth.
|
88 |
17130470
|
We next attempted to drive beta-cell replication in p21-null mice by crossing them with rat insulin II promoter-murine PL-1 (islet-targeted placental lactogen transgenic) mice.
|
89 |
17130470
|
A G(1/S) proteome scan demonstrated that p21(cip1) loss was not associated with compensatory increases in other cell cycle inhibitors (pRb, p107, p130, p16, p19, and p27), although mild increases in p57 were apparent.
|
90 |
17130470
|
In summary, isolated p21(cip1) loss, as for pRb, p53, p18, and p27 and other inhibitors, results in normal beta-cell development and function, either because it is not essential or because its function is subserved or complimented by another protein.

Several genes in this imprinted cluster encode proteins involved in growth regulation, e.g. the paternally expressed IGF2 and the maternally expressed cell-cycle regulator cyclin dependent kinase inhibitor, CDKN1C.

We showed that further epigenetic defects did not occur in the groups of SRS with LOM of ICR1 or mUPD7, and that these subentities do not belong to the diseases with a general hypomethylation defect, such as TNDM and BWS.

Analysis of the IGF2/H19 imprinting control region uncovers new genetic defects, including mutations of OCT-binding sequences, in patients with 11p15 fetal growth disorders.
|
105 |
20007505
|
The imprinted expression of the IGF2 and H19 genes is controlled by the imprinting control region 1 (ICR1) located at chromosome 11p15.5.

106 |
20007505
|
DNA methylation defects involving the ICR1 H19/IGF2 domain result in two growth disorders with opposite phenotypes: an overgrowth disorder, the Beckwith-Wiedemann syndrome (maternal ICR1 gain of methylation in 10% of BWS cases) and a growth retardation disorder, the Silver-Russell syndrome (paternal ICR1 loss of methylation in 60% of SRS cases).
|
107 |
20007505
|
Although a few deletions removing part of ICR1 have been described in some familial BWS cases, little information is available regarding the mechanism of ICR1 DNA methylation defects.
|
108 |
20007505
|
We investigated the CTCF gene and the ICR1 domain in 21 BWS patients with ICR1 gain of methylation and 16 SRS patients with ICR1 loss of methylation.
|
109 |
20007505
|
We identified four constitutional ICR1 genetic defects in BWS patients, including a familial case.
|
110 |
20007505
|
Our data extends the spectrum of constitutive genetic ICR1 abnormalities and suggests that extensive and accurate analysis of ICR1 is required for appropriate genetic counseling in BWS patients with ICR1 gain of methylation.

113 |
20738330

Whereas TNDM patients with MLH show clinical symptoms different from carriers with isolated 6q24 aberrations, MLH carriers diagnosed as BWS or SRS present only the syndrome-specific features.

However, several patients with transient neonatal diabetes mellitus (TNDM), Silver-Russell syndrome (SRS) and Beckwith-Wiedemann syndrome (BWS) exhibiting multilocus hypomethylation (MLH) have meanwhile been described.
|
123 |
20738330
|
Whereas TNDM patients with MLH show clinical symptoms different from carriers with isolated 6q24 aberrations, MLH carriers diagnosed as BWS or SRS present only the syndrome-specific features.
|
124 |
20738330
|
Interestingly, SRS and BWS patients with nearly identical MLH patterns in leukocytes have been identified.
|
125 |

|
Despite mutation screening of several factors involved in establishment and maintenance of methylation marks including ZFP57, MBD3, DNMT1 and DNMT3L the molecular clue for the ICR1/ICR2 hypomethylation in our patients remained unclear.

Here, we generated germline transgenic zebrafish with overexpression of pituitary tumor transforming gene (PTTG/securin) targeted to the adenohypophyseal proopiomelanocortin (POMC) lineage, which recapitulated early features pathognomonic of corticotroph adenomas, including corticotroph expansion and partial glucocorticoid resistance.
|
127 |

|
Molecular analyses in vitro and in vivo showed that R-roscovitine suppresses ACTH expression, induces corticotroph tumor cell senescence and cell cycle exit by up-regulating p27, p21 and p57, and downregulates cyclin E expression.

The imprinted 11p15 region is organized in two domains, each of them under the control of its own imprinting control region (ICR1 for the IGF2/H19 domain and ICR2 for the KCNQ1OT1/CDKN1C domain).
|
129 |
21780245
|
Disruption of 11p15 imprinting results in two fetal growth disorders with opposite phenotypes: the Beckwith-Wiedemann (BWS) and the Silver-Russell (SRS) syndromes.
|
130 |
21780245
|
Various 11p15 genetic and epigenetic defects have been demonstrated in BWS and SRS.
|
131 |
21780245
|
To investigate whether cryptic copy number variations (CNVs) involving only part of one of the two imprinted domains account for 11p15 isolated DNA methylation defects, we designed a single nucleotide polymorphism array covering the whole 11p15 imprinted region and genotyped 185 SRS or BWS cases with loss or gain of DNA methylation at either ICR1 or ICR2.
|
132 |
21780245
|
We describe herein novel small gain and loss CNVs in six BWS or SRS patients, including maternally inherited cis-duplications involving only part of one of the two imprinted domains.
|
133 |
21780245
|
We also show that ICR2 deletions do not account for BWS with ICR2 loss of methylation and that uniparental isodisomy involving only one of the two imprinted domains is not a mechanism for SRS or BWS.

No evidence for pathogenic variants or maternal effect of ZFP57 as the cause of Beckwith-Wiedemann Syndrome.
|
135 |
21863059
|
Beckwith-Wiedemann syndrome (BWS) is an overgrowth syndrome, which, in 50-60% of sporadic cases, is caused by hypomethylation of KCNQ1OT1 differentially methylated region (DMR) at chromosome 11p15.5.
|
136 |
21863059
|
Recently, recessive mutations of the ZFP57 gene were reported in patients with transient neonatal diabetes mellitus type 1, showing hypomethylation at multiple imprinted loci, including KCNQ1OT1 DMR in some.
|
137 |
21863059
|
The aim of our study was to determine whether ZFP57 alterations were a genetic cause of the hypomethylation at KCNQ1OT1 DMR in patients with BWS.
|
138 |
21863059
|
We sequenced ZFP57 in 27 BWS probands and in 23 available mothers to test for a maternal effect.
|
139 |
21863059
|
We identified three novel, presumably benign sequence variants in ZFP57; thus, we found no evidence for ZFP57 alterations as a major cause in sporadic BWS cases.

Studies of rare human imprinting disorders such as familial hydatidiform mole, Beckwith-Wiedemann syndrome and familial transient neonatal diabetes mellitus have enabled the identification of genetic (e.g., mutations in KHDC3L [C6ORF221], NLRP2 [NALP2], NLRP7 [NALP7] and ZFP57) and environmental (assisted reproductive technologies) factors that can disturb the normal trans mechanisms for imprinting establishment and/or maintenance.
