... I injected DNA into mouse embryos, using a special reporting system to see if CTCF was active or not. Dependent upon whether the DNA contained a binding site for CTCF so that CTCF could bind and function, or contained no such binding site, different signals were expected. However, I could not observ ...

To investigate the function of the SpLox gene in the embryo, genespecific morpholino antisense oligonucleotides (MASO) were injected into fertilized eggs to silence the gene by blocking production of the protein, and the phenotype of the resultant embryos and larvae was analyzed. Control injected la ...

... Many computational methods have also been proposed to predict TFBSs [12-19]. These methods are mostly based on the idea that the binding of a TF is mediated by the recognition of its binding motif represented as a position specific scoring matrix (PSSM). PSSMs are usually discovered as those enrich ...

Epigenetics in learning and memory

While the cellular and molecular mechanisms of learning and memory have long been a central focus of neuroscience, it is only in recent years that attention has turned to the epigenetic mechanisms behind the dynamic changes in gene transcription responsible for memory formation and maintenance. Epigenetic gene regulation often involves the physical marking (chemical modification) of DNA or associated proteins to cause or allow long-lasting changes in gene activity. Epigenetic mechanisms such as DNA methylation and histone modifications (methylation, acetylation, and deacetylation) have been shown to play an important role in learning and memory.
