Interestingly, transformation frequencies obtained with pAVA2 13-41 (Table 2) were about 50-100 times lower than with pAVA2 13-8. This indicates that replacement recombination is more efficient than Campbell-like i ...

Since the p53-binding domain is retained in Brca11700T, p53 may still bind to the mutant protein and, in the absence of the Brca1 C-terminal co-activation domain, become sequestered in an inactive complex. Lethality of Brca1D11/D11 embryos occur at 12.5–18.5 d.p.c. (19,22), thus showing that the Brc ...

Cancer epigenetics



Cancer epigenetics is the study of epigenetic modifications to the genome of cancer cells that do not involve a change in the nucleotide sequence. Epigenetic alterations are as important as genetic mutations in a cell’s transformation to cancer, and their manipulation holds great promise for cancer prevention, detection, and therapy. In different types of cancer, a variety of epigenetic mechanisms can be perturbed, such as silencing of tumor suppressor genes and activation of oncogenes by altered CpG island methylation patterns, histone modifications, and dysregulation of DNA binding proteins. Several medications which have epigenetic impact are now used in several of these diseases.
