... Answer: These results can be explained by gene conversion. The gene conversion took place in a limited region of the chromosome (within the pdx-1 gene), but it did not affect the flanking genes (pyr-1 and col-4) located on either side of the pdx-1 gene. In the asci containing two pdx-1 alleles and s ...

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.
