Developmental changes in brain template active region chromatin. 1981

L Uphouse, and B Tedeschi, and H Brown

The percentage of brain or liver chromatin in the template-active region was examined in rats of varying ages. Prenatally, there was an increase in the percentage of brain template-active region chromatin which declined near birth. After birth, the percentage of brain template-active region chromatin again increased to 3-6 days of age and then declined to adult levels at about 15 days of age. Liver exhibited a similar gestational change in the percentage of template-active region chromatin, but there was no recovery from the birth decline during postnatal development. These findings are discussed in terms of their contribution to the understanding of age-dependent changes in brain transcription.

D001921 Brain The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM. Encephalon

D005865 Gestational Age The age of the conceptus, beginning from the time of FERTILIZATION. In clinical obstetrics, the gestational age is often estimated from the onset of the last MENSTRUATION which is about 2 weeks before OVULATION and fertilization. It is also estimated to begin from fertilization, estrus, coitus, or artificial insemination.
