The effect of acute ethanol administration on pentylenetetrazole-induced c-fos expression in rat brain was studied. Pentylenetetrazole induced the rapid and transient expression of c-fos mRNA in rat brain. Maximal induction at a dose of 30 mg/kg was detected within 30 min and persisted for 60 min. Thereafter c-fos gene expression decreased to control levels by 180 min. No increase in c-fos mRNA was evident at doses of pentylenetetrazole less than or equal to 20 mg/kg, whereas maximal elevation was seen at 30 to 40 mg/kg. This action was inhibited by acute ethanol treatment (blood alcohol level greater than or equal to 100 mg/dl). Acute ethanol treatment alone had no effect on c-fos gene expression.

D010433 Pentylenetetrazole A pharmaceutical agent that displays activity as a central nervous system and respiratory stimulant. It is considered a non-competitive GAMMA-AMINOBUTYRIC ACID antagonist. Pentylenetetrazole has been used experimentally to study seizure phenomenon and to identify pharmaceuticals that may control seizure susceptibility.

D011518 Proto-Oncogene Proteins Products of proto-oncogenes. Normally they do not have oncogenic or transforming properties, but are involved in the regulation or differentiation of cell growth. They often have protein kinase activity.

D011519 Proto-Oncogenes Normal cellular genes homologous to viral oncogenes. The products of proto-oncogenes are important regulators of biological processes and appear to be involved in the events that serve to maintain the ordered procession through the cell cycle. Proto-oncogenes have names of the form c-onc. Proto-Oncogene,Proto Oncogene,Proto Oncogenes

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
