But as you said, as an individual eats a high - fat diet or is exposed to other types of environmental exposures, the ability of the liver to adapt involves turning on and turning off certain liver genes to control the liver's activity, and that's mediated through these epigenetic mechanisms that modify the activity of established liver genes.

Other medical sequencing projects will use DNA sequencing to: discover new genes that are involved in common diseases; identify the genes responsible for dozens of relatively rare, single - gene (autosomal Mendelian) diseases; sequence all of the genes on the X chromosome from affected individuals to identify those involved in sex - linked diseases; and survey the range of variants in genes known to contribute to certain common diseases.

This involves a feedback loop where BZR1 directly represses certain boundary identity genes (e.g., CUC and LOF) and others (e.g., LOB) function to keep BR from accumulating in the boundaries through direct activation of BAS1 (Neff et al., 1999; Bell et al., 2012).
