Imprinting disorders

Nature Reviews Disease Primers, 2023
Imprinting disorders (ImpDis) are congenital conditions that are characterized by disturbances of genomic imprinting. The most common individual ImpDis are Prader-Willi syndrome, Angelman syndrome and Beckwith-Wiedemann syndrome. Individual ImpDis have similar clinical features, such as growth disturbances and developmental delay, but the disorders are

Molecularly imprinted beads by surface imprinting

Analytical and Bioanalytical Chemistry, 2007
Molecular imprinting is a state-of-the-art technique for imparting molecular recognition properties to a synthetic polymeric matrix. Conventionally, the technique is easily carried out using bulk imprinting, where molecularly imprinted polymers (MIPs) are prepared in large chunks and post-treatment processes like grinding and sieving are then required.

Genomic Imprinting: Imprinting with and without methylation

Current Biology, 1994
Methyltransferase-deficient mice reveal that DNA methylation is required for the somatic-cell maintenance of parental imprinting, which alters the expression of a gene according to the parent from which it was inherited.

Imprinting

The International Journal of Developmental Biology, 1998
Imprinting provides a fascinating mechanism of control of gene expression so that the maternal and paternal alleles of some genes are unequally expressed. Imprinting is most likely established during gametogenesis by a mechanism not completely clear, though DNA methylation probably plays a certain role.

Imprinting: A Reassessment

Science, 1965
Chicks exposed to a moving model during their critical period for imprinting will subsequently demonstrate a preference for that model if it is stationary. In preference tests with moving models, other preferences appear to over-ride the effects of the imprinting experience.

Imprinting in neuron

Neuroscience Research, 2006
Although most imprinted genes display parent-origin-specific gene expression in tissues where they are transcribed, some genes are imprinted in a tissue-specific manner. Genes that show brain-specific imprinting or brain-specific lack of imprinting present a unique opportunity to study the process of imprinting during tissue differentiation.

In Brief: Genomic imprinting and imprinting diseases

The Journal of Pathology, 2014
AbstractGenomic imprinting is an epigenetic process by which the male and the female germline confer different DNA methylation marks and histone modifications onto specific gene regions, so that one allele of an imprinted gene is active and the other one is silent.

Imprinting and disease

Seminars in Cell & Developmental Biology, 2003
Deregulation of imprinted genes has been observed in a number of human diseases such as Beckwith-Wiedemann syndrome, Prader-Willi/Angelman syndromes and cancer. Imprinting diseases are characterised by complex patterns of mutations and associated phenotypes affecting pre- and postnatal growth and neurological functions.

Impressions of imprints

Trends in Genetics, 1994
tWmCOME CRC INSTITLrIE, TENNIS COURT ROAD, CAMBPdDGE, UK 0321QR. Parental (genomic) imprinting means that a subset of autosomal loci are expressed in a parent-of-origin- dependent manner. Importandy, such patterns of gene expression do not conform to classical Mendelian in- heritance and have potentially far- reaching implications for genetics ...
