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.

Molecularly imprinted beads by surface imprinting
Analytical and Bioanalytical Chemistry, 2007Molecular 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, 1994Methyltransferase-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.

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.

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.

In Brief: Genomic imprinting and imprinting diseases
The Journal of Pathology, 2014AbstractGenomic 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.

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 ...

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.

Much laboratory research is based on the assumption that the learning of parental characteristics by young nidifugous birds is rooted on visual factors. Naturalistic observations of ground- and hole-nesting duck species, augmented by sound amplification equipment, indicate that hatchlings are exposed to the call of their mother for a relatively long ...

An experiment was performed to determine the effect on imprinting strength of forcing the following response during the critical period in chicks. Results of the procedures used indicate that although imprinting occurred with forced following, it was not as strong as it is when the following is voluntary.
