Glossary

Neuropeptide Y (NPY):
This is a neurotransmitter. In the amygdala, it’s presence is experimentally shown to reduce stress and anxiety

Histone Acetyltransferase (HAT):
These proteins add acetyl groups to histones which causes the surrounding DNA to loosen up and be available for transcription.

Histone Deacetylase (HDAC):
These proteins remove acetyl groups from histones which causes the surrounding DNA to tighten up around the histone.

DNA Methyltransferase (DNMT):
This protein can add methyl groups to CpG islands in the DNA. This can block transcription factors from binding to a gene promoter region preventing its transcription

CpG Island:
A cytosine-phosphate-guanine island is a section of DNA with a large numb of Cytosine followed by guanine pairs. These are usually found at gene promoter regions.

CBP:
CREB-Binding protein is a transcription factor with intrinsic HAT activity. It is shown to promote the transcription of NPY in the amygdala
