The annual salary for someone with the job title Physician Assistant-Medical may vary depending on a number of factors including industry, company size, location, years of experience and level of education.
Epigenetics Around the Web is a weekly roundup of the latest studies and news in the field of epigenetics presented by GLP sister site the Epigenetics Literacy Project. This week features a video by scientists from the Garvan Institute of Medical Research on how epigenetic changes lead to cancer and scientists devise a way to edit the epigenome. How epigenetic changes cause cancer. There is a classical view of cancer in which the disease arises via genetic mutations. These mutations cause changes in genes that can make the protein non-functional or over active. But as I pointed out in the December 2 Epigenetics Around the Web post, epigenetic changes can also cause similar changes in a cell. Hypermethylation of a gene important for DNA repair could inhibit the proteinâs activity.
There is plenty of evidence that demonstrates how epigenetic changes (and not changes in the DNA of a gene) have been passed on to the next generation. For example: 1  Drosophila melanogaster-the fruit fly has white eyes.2  Embryos develop in temperatures of 25 degrees Celsius.here are several epigenetic ways that a gene can be modified, that is having its expression altered without changes to its DNA. Two of the most widely studied are DNA methylation and histone modification. 1) DNA methylation-where methyl groups latch onto parts of a DNA sequence and can switch a gene on or off.
